FOREWORD
The Ministry of Health, Community Development, Gender, Elderly and Children
(MoHCDGEC) is firmly committed to ensure safe, quality healthcare services to the
people of Tanzania and to provide protection from outbreaks of infectious diseases.
The infection prevention and control guidelines contained in this document are a
reflection of this commitment.
Also, Antimicrobial Resistance (AMR) in our Health Facilities has been increasing to
an alarming rate. This has made the MoHCDGEC to develop an AMR Action Plan
(2017-2022) to address the situation. Among the priority areas articulated in the
Action Plan is “Infection Prevention and Control in health care”. This means that the
revised guideline has come timely given its potential for contributing to the efforts to
control the spread of antimicrobial resistance in our healthcare settings. Therefore,
all Health Facilities need to implement the recommended practices and actions in
this guideline to ensure patient and staff safety as well as prevent spread of
antimicrobial resistant pathogens.
Implementation of this guideline is also pivotal in making Health Facilities capable of
handling threats from Viral Haemorrhagic Fevers (VHFs) such the Ebola Virus
Disease (EVD). This revised guideline has provided a specific chapter 26, which
provides guidance on the recommended IPC practices when handling suspected or
confirmed cases of VHFs.
The purpose of this document is to provide all healthcare providers with basic
infection prevention and control guidelines and safety precautions applicable in their
day-to-day activities.
The MoHCDGEC is dedicated to strengthen and support these practices and will
ensure proper implementation through increased budgetary allocations to meet the
requirements for improved infection prevention and control. Likewise, the combined
efforts of every healthcare worker will ultimately result in improved quality of care for
all patients and health personnel.

HOW TO USE THIS MANUAL
Infection prevention and control is multidisciplinary and requires compliance by all
levels of healthcare providers. Infection prevention deals primarily with preventing
the spread of infectious diseases through the air, blood or body fluids, faecal-oral
and food-borne. Such compliance is obligatory to prevent and control nosocomial
and other infections in healthcare settings as well as in the community. These
guidelines have been developed by the Ministry of Health, Community Development,
Gender, Elderly and Children (MoHCDGEC) of Tanzania to aid health workers to
understand and use evidence-based infection prevention practices.
viii
These guidelines are made up of five chapters (parts) as follows:
i. Part I: Background
ix
PART I: BACKGROUND
1.0. INTRODUCTION
Health care associated infections occur as results of health care in facilities or in the
community. Infections can take place in all types of health facilities and can be major
causes of death or morbidity in many facilities worldwide. At any one time, over 1.4
million people worldwide suffer from infectious complications of health care. Health
care workers may also be infected. These Health care associated infections cause
problems in healthcare settings globally.
Transmission of infection continues to be a major problem in Tanzania with the
burden of infectious disease very high, as reflected in the Tanzania HIV Impact
Survey (THIS), a household based national survey, which was conducted between
October 2016 and August 2017 to measure the status of Tanzania’s national HIV
response:
• Prevalence of HIV among adults, ages 15 to 64 years in Tanzania is 5.0 percent
(6.5 percent among females and 3.5 percent among males). This corresponds to
approximately 1.4 million people living with HIV (PLHIV) ages 15 to 64 years in
Tanzania;
• Annual incidence of HIV among adults aged 15 to 64 years in Tanzania is 0.29
percent (0.40 percent among females and 0.17 percent among males). This
corresponds to approximately 81,000 new cases of HIV annually among adults’
ages 15 to 64 years in Tanzania.
• A total of 65,902 cases of all forms were notified in 2016, which shows an
increase of 5.6% or 3507 cases compared to the year 2015. Among the cases
notified, new and relapse cases were 64,404 (95.5%) of which 27,655 (39%) were
bacteriological confirmed (TB programme, 2016)
Furthermore more, the world is facing threat of emerging and re-emerging infections
such as Ebola viruses as indicated by the World Health Organization as of year 2014,
around 10,000 people have been influenced with Ebola infection. The episode of
Ebola in African locale is courged with a high death rate.
Diarrhoeal diseases are the second leading cause of death in children under five
years old. These are both preventable and treatable. Each year diarrhoea kills
around 525 000 children under five. A significant proportion of diarrhoeal disease can
be prevented through safe drinking-water and adequate sanitation and hygiene.
Globally, there are nearly 1.7 billion cases of childhood diarrhoeal disease every year.
Diarrhoea is a leading cause of malnutrition in children under five years old
according to WHO, 2017.
The World Health Organisation recommends the emergence of life-threatening
infections such as severe acute respiratory syndrome (SARS) and viral
haemorrhagic fevers (e.g., Ebola and Marburg viral infections), Cholera, HIV and
1
AIDS as well as increase the magnitude of antimicrobial resistance highlight the
urgent need for efficient infection control practices in health care settings. Failure to
apply infection control measures favours the spread of pathogens, and health-care
settings can act as amplifiers of disease during outbreaks, with an impact on both
hospital and community health at large.

receiving healthcare services. Also, CDC healthcare-associated infection
(HAI) prevalence survey provides an updated estimate of the overall problem of HAIs
in U.S. hospitals. Based on a large sample of U.S. acute care hospitals, the survey
found that on any given day, about 1 in 25 hospital patients has at least one
healthcare-associated infection. There were an estimated 722,000 HAIs in U.S acute
care hospitals in 2011. About 75,000 hospital patients with HAIs died during their
hospitalizations. More than half of all HAIs occurred outside of the intensive care unit.
The direct and indirect costs of HAIs are estimated to total $97-147 billion annually.
1.1.3. Major types of HAIs
The four most common types of HAIs are related to invasive devices or surgical
procedures and include:
• Catheter-associated urinary tract infection (CAUTI)
• Central line-associated bloodstream infection (CLABSI)
• Surgical Site Infection (SSI)
• Ventilator-associated events (VAE)
A variety of organisms are responsible for many different types of HAIs. These
organisms causing HAIs include:
• Acinetobacter • Norovirus
• Burkholderia cepacia • Pseudomonas aeruginosa
• Clostridium difficile • Staphylococcus aureus
• Enterobacteriaceae (carbapenem- • Tuberculosis (TB)
resistance) • Vancomycin-
• Gram-negative bacteria intermediate Staphylococcus aureus
• Klebsiella • Vancomycin-
• Methicillin- resistant Staphylococcus aureus
resistant Staphylococcus aureus • Vancomycin-resistant Enterococci
(VRE)
The data mostly reflect reported cases and not the actual situation of the burden of
infectious disease in sub Saharan Africa, which may be much higher. Infectious
diseases, if not controlled, may lead to high rates of Healthcare Associated Infection
(those acquired in healthcare facilities). Infection prevention is therefore one of the
prerequisites for ensuring safe healthcare service delivery, as well as protecting the
population from outbreaks of infectious diseases.
2.0. RATIONALE
These guidelines for prevention and control of infectious diseases were updated due
the following reasons;
• Many healthcare providers have not had any updates of information related to
infection prevention despite the fact that over the past two decades many
changes have occurred due to the emergence of infections such as, Ebola,
HIV/AIDS and Influenza.
• Emerging and re-emerging of infectious diseases such as Viral Haemorrhagic
Fevers (VHF) and Influenza
• Availability of new scientific information that simplifies provision of safe and
effective prevention and control measures.
• An individual’s right to good health requires a safe healthcare environment for
both providers and clients.
• The HIV/AIDS epidemic has increased the risk for transmission of infections
of in the health care settings due to the various procedures conducted in
these facilities.
• There is increased awareness of how risky it is to work in healthcare facilities.
• Healthcare facilities are prone to infection transmission due to the following:
- Routine invasive procedures
4
- Exposure; infected or contaminated service providers may transmit
infectious agents among clients or one another
- Patients who are susceptible to infection because of compromised
immunity
- Patients who often have infections that can be easily transmitted to others
- Services that are sometimes provided in congested physical settings
Infection prevention and control is important for patients, clients, healthcare service
providers and communities as follows.
2.1.1. Patients /Clients
5
3.2. Objectives
1. To protect patients /clients from nosocomial infections
2. To protect health care workers from occupational infections
3. To protect communities from infectious diseases
4. To prevent the environment from pollution
6
PART II: FUNDAMENTALS OF INFECTION PREVENTION AND CONTROL
4.0. THE INFECTIOUS DISEASE TRANSMISSION CYCLE
Infectious bacteria, viruses and other microorganisms successfully survive and
spread infections wherever favourable conditions exist. Essential factors in the
transmission of disease producing microorganisms from person to person are
illustrated below.
7
4.1. Modes of Transmission
There are several ways in which diseases can be transmitted:
Direct
• Contact e.g. Haemorrhagic fever virus, enteric pathogens, MDR Bacteria,
HBV, HIV (blood)
• Droplet e.g. Influenza and Rubella viruses, Diphtheria
• Airborne e.g. TB, Chicken pox and Measles
Indirect
• Faecal oral - Common vehicle e.g. (food, water) e.g. Salmonella, Cholera or
diarrhoea
• Vector borne e.g. malaria, dengue fever
Standard Precautions
Standard precautions are simple set of effective practice guidelines (creating a
physical, mechanical and chemical barrier) to protect healthcare workers and
patients from infection with a range of pathogens including blood-borne pathogens.
The practices are used when caring for all patients regardless of their diagnosis.
4.1.1. Purposes of Practicing Standard Precautions
The purposes for practicing standard precautions are:
• To prevent and reduce the risk of transmitting microorganisms from known or
unknown sources of infection (e.g., patients, contaminated objects, used
needles and syringes, etc.) within the healthcare environment
• To prevent patients/clients from hospital acquired infections or health care
related infections.
• To protect health care workers (HCWs) from occupational infections
• To protect communities from acquiring infectious diseases
• To prevent environmental pollution
4.1.2. Principles of Practicing Standard Precautions Components
Every HCW should:
• Consider every person (patient/clients or staff) as potentially infectious and
susceptible to infection
• Use appropriate hand hygiene techniques including; routine hand washing,
hand antisepsis, antiseptic hand rub and surgical hand scrub
• Wear personal protective equipment which include: boots, aprons, gowns,
gloves, masks, protective eyewear and caps
• Appropriately handle sharps, patient care and resuscitation equipment and
appropriately manage patient placement and environmental cleaning.
• Not recap needles.
8
• Safely dispose of infectious waste materials to protect those who handle
them and prevent injury or spread to the community
• Promptly and carefully clean up spills of blood and other body fluids after the
spill event.
• Process instruments by cleaning, and sterilization or high-level disinfection
following recommended procedures
• Introduce cough etiquette to patients, caregivers and visitors with signs and
symptoms of respiratory illness, including cough, congestion, rhinorrhoea, or
increased production of respiratory secretions.
• Triage technique should be applied to isolate patients and clients with
respiratory problems.
9
instruments or other inanimate objects in the patient environment. Examples where
Contact Precautions apply include clients/patients/residents with
• Clostridium difficile
• Gastroenteritis
• Undiagnosed diarrhoea
• Scabies
• Pediculosis (Head Lice)
Patient Placement
• Preferred accommodation in acute care for Contact Precautions is a single
room with a dedicated toilet and patient sink.
• If single rooms are unavailable, clients / patients / residents may be cohorted
with other clients/patients/residents who are infected with the same
microorganism.
• Infection risk to other occupants of the room must be considered when
selecting roommates.
Personal Protective Equipment
• Where patients or residents are placed in isolation rooms, a disposable gown
and gloves must be worn on entering the patient’s isolation room.
• Gloves must be removed and hands cleaned on exit from the room.
• Wear gloves and gown/ apron only when there is bodily contact (i.e. HCW’s
clothing will have direct contact with the patient) or potentially contaminated
environmental surfaces or equipment in close proximity to the patient.
• Remove and discard gloves before removing gown / apron.
• Clean hands after removing each PPE.
• Where there is no bodily contact, hand hygiene is to be practised according
to 7 moments. Remove gown before leaving the patient-care environment
and perform hand hygiene immediately.
Environmental control
• Clients/patients/residents care items, bedside equipment and frequently
touched surfaces are to be cleaned daily.
• Clean the environmental surfaces with hospital-approved disinfectants
• Al surfaces should be decontaminated with a minimal dilution of sodium
hypochlorite disinfectant of 0.5% (or 5,000 parts per million available
chlorine); for MDRO patients in a cubicle, the environment is best cleaned
with sodium hypochlorite disinfectant with 2% available chlorine.
Patient - care equipment and linen
• Where possible, dedicate the use of non-critical patient-care equipment and
items such a stethoscope, sphygmomanometer or bedside commode to a
single client/patient/resident (or cohort of clients/patients/residents infected or
10
colonised with the pathogen) to avoid sharing between
clients/patients/residents.
• If use of common equipment or items is unavoidable, then adequately clean
and disinfect them before use on another client/patient/resident.
• Contaminated linen should be handled as little as possible to prevent gross
microbial contamination of the air.
• Linen from the clients/patients/residents’ isolation room should be handled as
per this guideline.
Clients/patients/residents transport
• Clients/patients/residents movement and transport from the room should be
limited unless for essential purposes.
• If clients/patients/residents need to be transported out of the room, inform the
receiving department of the need for Contact Precautions.
• Staff who accompany the client/patient/resident during the transportation are
to discard gown and gloves and perform hand hygiene before leaving the
room.
• They need not put on gown / apron and gloves during transportation. This is
to prevent environmental contamination that could occur through
contaminated gloves and gowns/apron.
• Clients/patients/residents who are respiratory dispersers should wear a
surgical mask en-route.
• Infection prevention and control precautions should be maintained to
minimise the risk of transmission of micro-organisms to other
clients/patients/residents and contamination of environmental surfaces or
other equipment.
• The linen trolley should be removed for washing after transfer of
clients/patients/residents.
• Clean or wipe trolley/ wheelchair with hospital-approved disinfectant.
Communication
• Infection Prevention and Control staff should inform clinical staff via e-mail or
phone call to update them on the Contact Precautions to be taken.
• The need for Contact Precautions can be identified using coloured stickers in
patient case sheets, ‘O slot’ vision outside the patient room, OT chit, and
electronic tagging to inform all HCPs on the precautions to be taken.
4.2.2. Droplet Transmission
Droplets are generated from the source person primarily during coughing, sneezing
and talking or during the performance of certain procedures such as resuscitation,
suctioning and bronchoscopy. Transmission occurs when droplets containing
microorganisms generated by the infected person are propelled a short distance
through the air and deposited on the host’s conjunctivae, nasal mucosa, or mouth.
11
For transmission to occur, the source and the susceptible host need to be within
approximately one meter (3 feet) of one another.
4.2.2.1. Droplet Precautions
Droplet Precautions when used in addition to Standard Precautions are intended to
prevent transmission of pathogens spread through close respiratory or mucous
membrane contact with respiratory secretions. Examples where Droplet Precautions
are indicated include patients with the following infectious agents:
• B. pertussis
• Influenza virus
• Adenovirus
• Rhinovirus
• N. meningitidis
• Goup A Streptococcus (for the first 24 hours of antimicrobial therapy).
Patient Placement
• A single patient room is preferred for patients who require Droplet
Precautions.
• When a single-patient room is not available, consultation with infection
prevention and control personnel is recommended to assess the various risks
associated with other patient placement options (e.g. cohorting, keeping the
patient with an existing roommate).
• Spatial separation of > 1 m and drawing the curtain between patient beds is
especially important for patients in multi-bed rooms with infections
transmitted by the droplet route.
• Droplet Precautions signage for the appropriate Personal Protective
Equipment to be worn should be place before entering patient room to guide
people on the precautions to be taken.
• Steps on appropriate PPE removal should also be displayed.
Personal Protective Equipment (PPE) / Hand Hygiene
• Healthcare personnel should wear a surgical mask for close contact with an
infectious patient; the mask is generally donned upon room entry.
• Patients on Droplet Precautions who must be transported outside of the room
should wear a mask if tolerated and follow Respiratory Hygiene/Cough
Etiquette.
• Staff should perform hand hygiene according to 7 moments of this guideline.
• After leaving the patient-care environment and removing the surgical mask,
staff must perform hand hygiene immediately.
Environmental Control
• Patient-care items, bedside equipment and frequently touched surfaces are
cleaned daily or as deemed necessary.
12
• Clean the environmental surfaces with hospital-approved disinfectants.
Patient - care equipment and linen
• Where possible, dedicate the use of non-critical patient-care equipment and
items such a stethoscope, sphygmomanometer or bedside commode to a
single patient (or cohort of patients infected or colonised with the pathogen)
to avoid sharing between patients.
• If use of common equipment or items is unavoidable, then adequately clean
and disinfect them before use on another patient.
• Contaminated linen should be handled as little as possible to prevent gross
microbial contamination of the air.
• All linen from the patient’s isolation room should be handled as per this
guideline.
Patient Transport
• Patient movement and transport from the room should be limited unless for
essential purposes.
• If a patient needs to be transported out of the room, inform the receiving
department of the need for Droplet Precautions.
• Staff involved in the patient’s transfer should wear appropriate PPE during
transportation.
• The patient should wear a surgical mask and follow Respiratory Hygiene
/Cough Etiquette in order to minimise the dispersal of droplet nuclei during
transportation.
• Infection prevention and control precautions should be maintained to
minimise the risk of transmission of microorganisms to other patients and
contamination of environmental surfaces or other equipment.
• The linen on the trolley should be removed for washing after transfer of
patient.
• Clean or wipe trolley/ wheelchair with hospital-approved disinfectant.
Communication
• Infection Prevention and Control staff should inform clinical staff via e-mail or
phone call to update them on Droplet Precautions to be taken.
• The need for Droplet Precautions can be identified using coloured stickers in
the patient case sheet, ‘O slot’ vision outside the patient room, OT chit, or
electronic tagging to inform all healthcare on the precautions to be taken.
14
• Aerosol-generating procedures associated with risk of pathogen transmission
(e.g. Intubation, bronchoscopy) should be performed using appropriate PPE
in an Air.
Personal Protective Equipment (PPE)
• Airborne Precautions are used in addition to Standard Precautions for
patients known or suspected of having airborne transmission illness.
• Wear approved N95 or higher-level respirators are used to prevent inhalation
of small particles that may contain infectious agents transmitted via the
airborne route.
• Healthcare personnel should wear a fit-tested an approved N95 or higher-
level respirator for respiratory protection before entering the room of a patient
who requires airborne precautions.
• Perform user-sealed check of N95 mask or respirator each time it is being
donned to minimise leakage around the face piece.
• Avoid touching or fiddling with the mask once the mask is properly applied.
• Change the respirator if wet or soiled. Remove N95 mask or respirator
correctly outside the patient room or in changing room and ensure that the
door of the patient room is closed.
• Discard respirator into appropriate waste bin and perform hand hygiene
immediately.
Environment Controls- Equipment /Consumables
• Dedicated use of non-critical patient-care equipment and items such a
stethoscope, sphygmomanometer and thermometer are recommended.
• If use of common equipment or items is unavoidable, ensure adequate
cleaning and decontamination of the equipment or items after and between
patient use.
• Contaminated linen should be handled as little as possible to prevent gross
microbial contamination of the air and is to be managed as per hospital
protocol.
Environment Controls- Dishware and eating utensils
• The combination of hot water and detergents used in dishwashers is
sufficient to decontaminate dishware (e.g., dishes, glasses, cups) and eating
utensils.
• Therefore, reusable dishware and utensils may be used for patients.
• Disposable dishes and eating utensils may be used if there are no adequate
resources for cleaning dishes and utensils.
Environment Cleaning
• Daily environmental and surface cleaning of the isolation room with hospital
approved disinfectant is recommended.
• Pay special attention to cleaning frequently touched surfaces.
15
Personnel Restriction
• Whenever possible, susceptible HCWs should not enter the rooms of patients
known or suspected to have Measles (rubella), Varicella (chickenpox),
disseminated Zoster, or Smallpox.
Visitors
• Visitors who are non-household contacts should be discouraged from visiting.
They should be counselled about their risk and taught how to use an N95
respirator appropriately if they do visit.
Patient Transport
• Patient movement and transport from the room should be limited unless for
essential purposes.
• If a patient needs to be transported out of the room, inform the receiving
department of the need for airborne precautions.
• Healthcare personnel should wear an N95 mask or respirator during
transportation of patients. Patients should wear a surgical mask if tolerable
and follow Respiratory Hygiene /Cough Etiquette in order to minimise the
dispersal of droplet nuclei during transportation.
Communication
• Display an airborne precaution sign outside the isolation room to alert and
guide HCWs on the wearing of appropriate PPE.
• Indicate on investigation or procedure request forms (e.g. Radiology,
Physiotherapy, operation etc.) that the patient is on airborne infection
isolation precautions to alert HCWs on the infection risk.
Notify the receiving department or health facility before transporting or transferring
the patient to allow adequate preparation of infection prevention and control
measures.
4.2.4. Common Vehicle Transmission
Common vehicle transmission applies to microorganisms transmitted by
contaminated items such as:
• Foods – e.g., Salmonella
• Water – e.g., Shigellosis
• Injections/ intravenous solutions – e.g., HIV, Hepatitis B
• Blood – e.g., Hepatitis B, C, HIV
• Equipment and devices – e.g., HIV, Hepatitis B
Measures for control
• Health education and promotion
• Food safety and food hygiene
16
— Clean food preparation areas and kitchenware with soap and safe water/
chlorine or acetic acid (vinegar) and let dry completely before reuse
— Wash hand before and after eating food
— Wash fruits and vegetables with chlorine 0.001%
— Observe food hygiene
— Cook food well, keep it covered, eat it hot, and peel fruits and vegetables.
— Be sure to cook seafood, especially shellfish, until it is very hot all the way
through.
— Avoid raw foods other than fruits and vegetables you have peeled
yourself.
— Clean up safely— in the kitchen
• Drink safe water
— Boil it or treat it with a 0.001% chlorine product or household bleach.
— If boiling, bring your water to a complete boil for at least 1 minute.
— To treat your water with chlorine, use one of the locally available
treatment products and follow the instructions.
— If a chlorine treatment product is not available, you can treat your water
with household bleach.
— Always store your treated water in a clean, covered container.
— Piped water sources, drinks sold in cups or bags, or ice may not be safe
and should be boiled or treated with chlorine
• Practice hand hygiene as detailed in this guideline
• Health facility onsite water treatment and safe storage
• For the blood borne infections observe precautionary measures
• Health facility environmental cleaning, waste management and safe last
office procedures
• Vaccinations
17
Measures for control
• Chemical control
- Manual space spraying of insecticides or indoor residual spraying
• Engineering control and barriers
— Screening of the health facilities
— Use of treated bed nets
• Environmental management
— Destruction of the breeding site in the health facilities areas
— Improve environmental cleanness
— Proper Waste management
— Proofing water storage containers
18
For patients who require both PE and airborne precautions (e.g., pulmonary or
laryngeal tuberculosis, acute varicella-zoster), use an anteroom to ensure proper air-
balance relative to the corridor and the PE room.
• Provide an independent exhaust of contaminated air to the outside.
• Place a HEPA filter in the exhaust duct if recirculated air.
• No carpeting in patient rooms or hallways.
• No upholstered furniture and furnishings. Use smooth and non-porous
surfaces and finishes that can be scrubbed or easily cleaned.
• No fresh or dried flowers or potted plants.
Personal Protective Equipment (PPE)
• Implement Standard Precautions for patients who are on protective
precautions.
• Gown, gloves and mask are NOT required for HCWs and visitors for routine
entry into the room.
• Practice good hand hygiene according to 7 moments for hand hygiene.
• Use appropriate PPE as indicated accordingly to standard precautions or for
suspect or proven infections for which transmission-based (contact, droplet,
airborne) precautions are required.
Equipment /Consumables
• Dedicate the use of non-critical patient-care equipment and items such a
stethoscope, sphygmomanometer and thermometer.
• If use of common equipment or items is unavoidable, ensure adequate
cleaning and decontaminating of the equipment or items after and between
patients used.
• Check opened and unopened wound-dressing supplies (e.g., adhesive
bandages, elastic adhesive tape) to detect mould contamination before using
on patients to prevent subsequent cutaneous transmission.
• Discard all bandages and wound dressings that are expired, have damaged
packaging, or are visually contaminated by construction debris or moisture.
Environment cleaning
• Avoid dusting methods that disperse dust.
• Daily wet-mopping of all horizontal surfaces including exhaust vent and
windows sill using cloths moistened with hospital approved detergent or
disinfectant.
• Prohibit exposures of patients to vacuum cleaning that could cause
aerosolization of fungal spores
• Use vacuum cleaner equipped with HEPA filters when vacuum cleaning is
necessary.
• Closed doors to patient rooms when vacuuming the corridors.
19
Personnel Restriction
• HCWs with diseases transmissible by air, droplet and direct contact (e.g.,
VZV, infectious gastroenteritis, HSV lesions of lips or fingers, and URIs)
should be restricted from patient contact and temporarily reassigned to other
duties.
• Health facilities should have a policy regarding the immunizations of HCWs
to prevent transmission of vaccine-preventable diseases to severely
immunocompromised patients.
• HCWs with blood borne viral infections (e.g., HIV, hepatitis B or C viruses)
need not be restricted from patient contact as long as they do not perform
high-risk procedures that could result in patient exposure to the HCW’s blood
or body fluids.
Visitors
• Restrict visitors with communicable infectious diseases (e.g., Upper
Respiratory Infections, flu-like illnesses and recent exposure to
communicable diseases) from visiting severely immunocompromised patients.
• All visitors must be able to understand and follow appropriate hand hygiene
before and after patient contact.
Patient transport
• Patient movement and transport from the room should be limited unless for
diagnostic or therapeutic procedures that cannot be done in the room.
• Should severely immunocompromised patients (e.g. HSCT) required to leave
the Protective Environment, they are advised to wear a high-efficiency
respirator (e.g. N95 mask) if tolerable to prevent inhalation of fungal spores
when there is construction, renovation or other dust-generating activities in
and around the healthcare facility.
• There is no recommendation for fit-testing of patients who are using
respirators.
• The use of masks or respirators by severely immunocompromised patients
when they are outside of the PE for prevention of environmental fungal
infections in the absence of construction or renovation has not been
evaluated.
• Minimize the length of time that patients who require a PE are outside their
rooms for essential purposes.
Communication
• Display a protective precaution signage outside the isolation room to alert
healthcare personnel. Notify receiving department or healthcare facility
before transporting or transferring patient to allow minimizing the length of
time patients is outside the PE.

5.0. WORKERS HEALTH AND SAFETY IN THE CONTEXT OF INFECTION
PREVENTION AND CONTROL
Health care workers are exposed to a number of hazards in the health facility, which
include blood and other body fluids, sharp objects, in the course of their routine work.
Consequently, they are at risk of infection with blood borne viruses including Human
Immunodeficiency Virus (HIV), Hepatitis B virus (HBV) and Hepatitis C Virus (HCV).
The risk of infection to HCWs depends on the nature and frequency of exposure.
For more details on health facility risks to workers refers (Refer National Guidelines
for Workers Health and Safety in the Health Care Facility Guidelines).
21
• Good environmental cleanliness, waste management and facility design and
layout [Engineering control]
• Standard and transmission-based IPC precautions, including safeguard and
appropriate use of personal protective equipment [PPE control].
• Improved water, sanitation and hygiene infrastructure and services
[Engineering control]
• A system for surveillance of key process and outcome indicators of IPC
performance, and dissemination of results [Administrative control]
• Systems to communicate with staff, patients and carers (e.g. to provide
information about HAI and IPC policies), and surveys to assess the systems’
efficacy. [Administrative control]
• improved work environment that consider need for differential-pressure
isolation rooms (e.g. negative-pressure rooms with anterooms) to isolate
patients with infectious diseases, including airborne respiratory infections
[Engineering control]
• Maintain the health and wellbeing of HCWs and patients in healthcare
facilities, including providing training on workplace improvement, recreational
areas, eat places, workers benefit and compensation right [Administrative
control]
• An IPC program should form part of a risk management system to identify,
assess, mitigate and communicate potential communicable disease threats
to patients and staff. [Administrative control]
• Workplace health and safety programs should identify all threats to staff
health—including infectious diseases—and take measures to eliminate or
mitigate risk [Elimination]
• Implementation of Standard Precaution [Engineering control &
Substitution]
• Immunization of all health workers, against Hepatitis B, Tetanus and other
immunizable diseases [Administrative control]
— Routinely immunization of health workers against infection with HBV is an
effective way to protect them.
— Conduct Pre-vaccination serological testing
— Measure level of antibody levels between two to six months after the last
dose
— Maintain register of healthcare workers received vaccination.
— Refer infected workers for appropriate care and treatment
— Liaise with Occupational Health and Safety focal person for workers
benefits and compensation
• Provision of post exposure prophylaxis [Administrative control]
- Clear policy guidelines and procedures posted in visible places
22
— Orient healthcare workers on PEP procedure
— Design a mechanism for exposure reporting procedures as per PEP
guidelines
— Conduct a thorough Assessment of exposure risk
· Type and severity of exposure
· Blood-borne infection status of source person
— Provide an appropriate treatment, follow-up, and counselling of workers
after exposure
— Confidentiality of exposed and source person
— Management of exposures training of healthcare personnel
— Rapid access to clinical care
· Post-exposure prophylaxis (PEP)
· Testing of source patients/exposed persons
Successful implementation of these strategies requires an effective quality
improvement or infection prevention, occupational health and safety, WASH and
HCWM with support from the health setting management team (Refer National
Guidelines for workers health and safety in the healthcare facility Guidelines)
23
6.0. HAND HYGIENE
Hand Hygiene is the most important and effective procedure to prevent and control
the spread of hospital associated infections (HAIs). It is the responsibility of all
HCWs to carry this out at the right moment during patient care. Effective hand
hygiene kills or removes transient bacteria on the skin via any of the following two
methods:
• Use of a 70 to 90% Alcohol-Based Hand Rub (ABHR) is the preferred
method (when hands are not visibly soiled) for cleaning hands. Using easily-
accessible ABHR in health care settings takes less time than traditional hand
washing and has been shown to be more effective than washing with soap
(even using an antimicrobial soap) and water when hands are not visibly
soiled.
• Hand washing with liquid soap and running water must be performed when
hands are visibly soiled. The effectiveness of alcohol is inhibited by the
presence of organic material. The mechanical action of washing, rinsing and
drying is the most important contributor to the removal of transient bacteria
that might be present. If hands are visibly soiled and running water is not
available, use a moistened towelette to remove the visible soil, followed by
ABHR.
Hand hygiene includes care of hands, nails, skin, use of lotions and surgical scrub.
Failure to perform appropriate hand hygiene is considered to be a leading cause of
nosocomial (hospital-acquired) infections and the spread of multi-resistant
microorganisms and has been recognized as a significant contributor to outbreaks of
disease (Boyce and Pittet 2002).
Hand hygiene can be done by
• Hand washing with liquid soap
• Hand washing with antiseptic agent
• Surgical hand hygiene
• Antiseptic hand rub using a waterless, alcohol-based antiseptic agent
24
Every HCW should consider the following moment before hand washing
• Immediately on arrival at work and before leaving work
• Before and after using the toilet
• Before and after each patient contact
• Before and after donning and doffing gloves before preparing, handling,
serving or eating food, and feeding a patient
• Before and after any clinical procedure
• Whenever there is a chance of contamination such as;
— Touching blood, body fluids, secretions, excretions, and exudates from
wounds
— Contact with items known or considered likely to be contaminated with
blood, body fluids, secretions, or excretions (e.g., bedpans, urinals,
wound dressings) whether or not gloves are worn
— Attending to children’s needs (after changing diaper or toilet, feeding and
breastfeeding) after personal body functions such as using the toilet,
wiping or blowing one’s nose
— Between all procedures done on the same patient where soiling of hands
is likely, to avoid cross-contamination of body sites.
• Ensure all patients and family members are educated in proper hand washing.
25
• Turn on tap.
• Wet hands thoroughly under running water at least 4 inches above the wrist.
• Soap hands adequately.
• Vigorously rub together all surfaces of lathered hands.
• Rub hands vigorously back and front, in between fingers up to and including
the wrist, followed by thorough rinsing under running water. This should be
for 10 – 15 seconds.
• Dry hands from tip of fingers to wrist with paper towel. If paper towels are not
available, shake off excess water and allow hands to air-dry.
• Use the same paper towel to turn off tap if tap not elbow controlled.
26
Important Notes
• Immediate re-contamination of the hands by touching sink fixtures may be
avoided by using paper towel to turn off taps.
• When running tap water is not available, use a bucket with a tap that can be
turned on to wet hands, off to lather hands and turned on again for rinsing.
Design of the taps/sinks and the right purchase of the taps, e.g., elbow, is
desirable.
• If a bucket with a tap is not available, a bucket/basin and pitcher can be
used to create a running stream of water. A helper can pour water from the
pitcher over the hands being washed.
• Hand washing should not be repeated in the same container of water.
• Hands should be dried with paper towels/sterile towels per procedure.
• Kills or inhibits the growth of most transient and resident micro-organisms but
does not remove micro-organisms or dirty.
• can be used when hand washing with soap and running water is not possible,
as long as hands are not visibly soiled with dirty, blood, or other organic
material
• Standard Operating Procedure for performing antiseptic hand rub is same as
normal hand washing.
The use of an antiseptic hand rub is more effective in killing transient and resident
flora than hand washing with antimicrobial agents or plain soap and water. It is quick
27
and convenient to perform and gives a greater initial reduction in hand flora (Girou et
al., 2002). Antiseptic hand rubs also contain a small amount of an emollient such as
glycerine, propylene glycol or sorbitol that protects and softens skin.
To be effective, an adequate amount of hand rub solution should be used. For
example, by increasing the amount of hand rub from 1 mL to 5 mL per application
(about 1 teaspoonful), the effectiveness is increased significantly (Larson, 1988).
**Note: Since antiseptic hand rubs do not remove soil or organic matter, if hands are
visibly soiled or contaminated with blood or body fluids, hand washing with soap and
water should be done first.
28
cooled; shake the flask gently to mix the content.
**Note: Only pharmacopoeia quality reagents should be used (e.g. The International
Pharmacopoeia) and not technical grade products.
29
6.1.4. Surgical Hand Hygiene
This procedure involves hand washing with water and soap, and hand rubbing with
alcohol-based hand rub and friction. The purposes of surgical hand hygiene are;
• To prevent wound contamination by microorganisms from hands and arms of
surgeons and assistants
• To prevent the growth of microorganisms (rubbing with antiseptic before
beginning surgical procedures)
30
6.2. Skin Care
It is important to note the following.
• Frequent hand washing and gloving can irritate skin.
• Hand washing cannot reduce the bacterial counts of personnel with
dermatitis.
• Staff responsible for processing instruments and who have open sores or
cuts on their hands or forearms should not clean instruments until the lesions
are healed unless covered with waterproof dressings.
• Healthcare providers with dermatitis carry high numbers of microorganisms
and may be at increased risk of exposure to blood-borne pathogens. Intact
skin is a major defence against infection.
• Lotion can ease the dryness resulting from frequent hand washing. It can
also help prevent dermatitis from frequent glove use.
• Do not use personal hand creams at work as it may counteract the antiseptic
properties in the antiseptic preparation.
• Hand cream containing oil should be avoided as they may cause latex gloves
to split.
• Provide alternative hand hygiene products for HCWs with confirmed allergies
or adverse reactions to standard products used in the health-care setting.

6.4. Hand Hygiene Strategy
All health facilities should allocate resources to plan and implement an ongoing
program on promoting excellent hand hygiene practices by staff, patients and visitors.
A self-assessment on current hand hygiene activities is recommended using a
standard Hygiene Self-Assessment Framework. This strategy includes the following:
6.4.1. Build Hand Hygiene Culture
Building Hand Hygiene culture is a vital component in Hand Hygiene Improvement
Strategy for all health-care facilities. It refers to ensuring that the health-care facility
has the necessary infrastructure in place to allow HCWs to practice hand hygiene.
Compliance with hand hygiene is only possible if the health facility setting ensures
an adequate infrastructure and if a reliable and permanent supply of hand hygiene
products at the right time and location is provided.
6.4.2. Training / Education
All HCWs require training and education on the importance of hand hygiene, the
indication on the 7 Moments of hand hygiene and the correct steps of hand hygiene.
Clear and standardized message need to be conveyed to all HCWs to ensure
consistency in hand hygiene. In addition, this is also to encourage behavioural and
cultural change.
6.4.3. Evaluation and feedback
Evaluation and repeated monitoring of a range of indicators indicating hand hygiene
practices and infrastructure including knowledge and perception of the problem of
healthcare-associated infection and the importance of hand hygiene is an important
aspect in improving hand hygiene. Continuous monitoring of any implementation that
had been introduced is essential to assess the effectiveness of the strategy in
improving hand hygiene in the institution.
6.4.4. Reminders in the workplace
Reminders are important to remind and prompt all HCWs on the importance of hand
hygiene and the 7 Moments to hand hygiene. Patients and visitors are also informed
of the standard of care that they should expect from their healthcare workers with
regards to hand hygiene through these reminders. Reminders can be visual such as
posters or audio such as via public announcements. Other initiatives can be in the
form of patient educational leaflets, badges etc.
6.4.5. Health Facility Hand Hygiene Policy
This refers to creating an environment and perceptions that facilitate awareness
about patient safety issues while guaranteeing consideration of hand hygiene
improvement as a high priority at all levels:
35
Table 3. Proposed Strategies to Improve Hand washing Techniques and
Compliance
Obstacle Strategy
Lack of knowledge • Education with supportive literature, videotaped
instructions, hand washing demonstrations;
frequent involvement of personnel in education
and feedback on infection rates
Lack of motivation • Direct observation and feedback on a regular
basis, role models; involvement of staff in
studies; application of new technologies
• Programmes on hand hygiene for patients and
families
Unavailability of • Hand washing facilities conveniently located
handwashing facilities throughout the healthcare facility
• Available running water
• Hand washing facilities in or adjacent to rooms
where healthcare procedures are performed •
Accessible, adequate supplies of soap and
disposable towels
• Waterless antiseptic agents readily available in
wall-mounted dispensers, or in small containers
for mobile care such as home care and for
emergency responders
Non-acceptance of hand • Availability of hand washing products that have
washing a high products level of acceptability to staff,
with appropriateness, cost, supply, etc. being
taken into consideration
Dermatitis • Lotions to prevent skin dryness
• Lotion supplies in small non-refillable containers
• Compatibility between lotion and antiseptic
products and effect on glove integrity
• Lotions approved by the Infection Prevention
and Control Committee
36
7.0. PERSONAL PROTECTIVE EQUIPMENT
Protective barriers, now commonly referred to as personal protective equipment
(PPE), have been used for many years to protect patients from microorganisms
present on staff working in healthcare settings. More recently, with the emergence of
AIDS, viral Hepatitis, VHF, and the resurgence of tuberculosis in our country, use of
PPE now has become important for protecting staff as well. As a consequence,
hospital administrators, supervisors and HCWs need to be aware not only of the
benefits and limitations of specific PPE, but also of the actual role PPE play in
preventing infection so that they can use them effectively and efficiently.
37
• Utility gloves are used for decontamination of large equipment, cleaning of
floors, walls, healthcare facility furniture such as beds, etc.
• Gloves shall be changed between care activities and procedures with the
same patient after contact with materials that may contain high
concentrations of microorganisms.
• Gloves shall be removed before moving to another patient or after completion
of specific task.
• Hands shall be washed and dried immediately after removing gloves.
• With the exception of utility gloves other gloves shall not be washed,
decontaminated and reused.
• Gloves shall not be worn while walking in corridors and traveling in elevators,
unless in special circumstances, e.g., transporting laboratory specimens.
Double Gloving
The transmission of HBV and HCV from surgeon to patient and vice versa has
occurred in the absence of breaks in technique and with apparently intact gloves
(Davis, 2001a). Even the best quality, new latex rubber surgical gloves may leak up
to 4% of the time. Moreover, latex gloves, especially when exposed to fat in wounds,
gradually become weaker and lose their integrity.
Although double gloving is of little benefit in preventing blood exposure if needle
sticks or other injuries occur, it may decrease the risk of blood-hand contact. For
example, one recent study showed that surgeons wearing single gloves had a blood-
hand contact rate of 14% while surgeons wearing double gloves had only a rate 5%
(Tokars et al., 1995; Tokars et al., 1992).
Based on this study, the following are reasonable guidelines for when to wear
double gloves:
• when the procedure involves coming into contact with a large amount of
blood or other body fluids (e.g., vaginal deliveries and caesarean sections)
• for orthopaedic procedures in which sharp bone fragments, wire sutures and
other sharps are likely to be encountered
Elbow Length Gloves for Obstetrical Procedures
Blood contact with the skin and mucous membranes of providers occurs in 25% of
vaginal deliveries and 35% of caesarean sections (Davis, 2001). Where the hand
and forearm need to be inserted into the vagina (manual removal of a retained
placenta) or deep into the uterus to deliver the infant’s head (caesarean section),
elbow-length, so-called “gauntlet” gloves/ gynaecological gloves help protect the
provider from significant blood and amniotic fluid contamination.

7.1.2. Scrub Suites and Gowns
Scrub suits or cover gowns are worn over, or instead of, street clothes. The main
use of cover gowns is to protect the HPs’ clothing. A scrub suit usually consists of
drawstring pants and a shirt. A V-neck shirt must not be cut so low as to slide off the
wearer’s shoulders or expose men’s chest hair.
Surgical gowns were first used to protect patients from microorganisms present on
the abdomen and arms of the HCW during surgery. Surgical gowns made of fluid
resistant materials do play a role in keeping blood and other body fluids off the skin
of personnel, particularly in operating, delivery and emergency rooms.
Lightweight cloth gowns offer little protection and do not provide an effective barrier
because moisture can easily pass through them, allowing contamination. Jeans
material (denim) or canvas, on the other hand, is too dense for steam penetration
(i.e., cannot be sterilized), is difficult to wash and takes too long to dry. The HCW can
wear a plastic or rubber apron underneath the gown to prevent contact of the skin
with blood and body fluids. If large spills occur, the best things to do is shower or
bathe as soon after completing the procedure as possible.
Standard Operating Procedures for Gowns
1. The unnecessary use of gowns is not recommended.
2. Gowns shall be used for protective isolation.
3. Gowns shall not be worn outside the area for which they are intended.
4. Long gowns shall be worn to protect uncovered skin and to prevent soiling of
clothing during procedures and patient care activities likely to generate
splashes or sprays of blood, body fluids, secretions, or excretions. Plastic
aprons are recommended where splashes are likely to occur.
5. Clinical coats and scrub suits should remain in the working place; taking them
home increases the risk of infection to the home environment.
7.1.3. Masks
Masks should be large enough to cover the nose, lower face, jaw and all facial hair
(to contain it). They are worn in an attempt to contain moisture droplets expelled as
HPs or surgical staff speak, cough or sneeze (droplet precautions), as well as to
prevent accidental splashes of blood or other contaminated body fluids from entering
the HCW’s nose or mouth. Unless the masks are made of fluid-resistant materials,
however, they are not effective in preventing either very well.
Respirators are specialized types of masks, called particulate respirators (such as
N-95), which are recommended for situations in which filtering inhaled air is
considered important (e.g., for the care of a person on airborne precautions). They
contain multiple layers of filter material and fit the face tightly so that no air leaks
around the mask when the HCW breathes.
39

(WHO) 2004.)
41
Standard Operating Procedures for Footwear
1. Rubber or leather boots are recommended because they protect better; they
should be kept clean and free of contamination from blood or other fluid spills.
2. Shoe covers are unnecessary if clean, closed-toe, sturdy shoes are available
for use only in surgical areas.
7.1.7. Apron
The apron is made of rubber or plastic to provide a waterproof barrier along the front
of the health worker’s body.
Figure 7. Hood
7.1.9. Drapes
Surgical drapes (sterile) made of cloth can be placed around a prepared surgical
incision to create a work area. Although this area is often called the “sterile field,” it is
NOT sterile. Cloth drapes allow moisture to soak through and can help to spread
organisms from skin, even after surgical cleansing with an antiseptic agent, into the
incision. Thus, neither sterile gloved hands nor sterile or high-level disinfected
instruments and other items should touch drapes once they are in place. Using towel
drapes to create a work area around the incision limits the amount of skin that needs
to be cleaned and reminds the surgical team not to touch the patient.
Remember:
• Once a sterile drape touches the patient’s skin, it is no longer sterile.
• Sterile cloth drapes do not replace good aseptic technique.
42
7.2. General Procedure for Donning PPE
Steps of donning PPE can vary depending on the procedure to be performed;
donning for theatre, isolation, and etc.
• Always perform hand hygiene before donning PPE
• If wearing a gown, don the gown first and fasten in back accordingly
• If wearing a facemask or respirator:
— Secure ties or elastic band at the back of the head and/or neck
— Fit flexible band to nose bridge
— Fit snug to face and below chin
• If wearing goggles or face shield, put it on face and adjust to fit
• If wearing gloves in combination with other PPE, don gloves last

8.0. ANTISEPTICS AND DISINFECTANTS
8.1. Antiseptics
Antiseptic chemicals that are applied to the skin or other living tissues to inhibit or
kill microorganisms (both transient and resident) thereby reducing the total bacterial
count.
Antisepsis
Process of reducing the number of microorganisms on the skin, mucous membranes
or other body tissues by applying an antimicrobial antiseptic agent.
Note: Antiseptics should not be used on inanimate objects such as instruments
and surfaces; they do not have same killing power as disinfectants. Although
antiseptics are sometimes used as disinfectants (e.g., Savlon or Dettol) for
processing instruments and other inanimate object; they are not designed for this
use. They do not have the same killing power as chemical disinfectants (e.g.,
glutaraldehydes, hypochlorite and per oxides) and should not be used for this.
purpose (Rutala, 1996).
Antiseptic Agents
• Liquid soap
• Antiseptics, which include 0.5% chlorhexidine with or without glycerol, and
povidone-iodine. These reduce both transient and resident flora on the hands.
• They also reduce the risk of infections in high-risk situations, such as:
— Heavy microbial contamination
— Before performing invasive procedures, (e.g., the placement and care of
intravascular devices and indwelling urinary catheters)
— Before contact with patients who have immune defects, damage to the
integumentary system (e.g., burns, wounds) and percutaneous implanted
devices
— Before and after direct contact with patients who have antimicrobial
resistant organisms.
45
• Iodine (3%); aqueous iodine and alcohol-containing (tincture of iodine)
products
• Iodophors (7.5–10%), various other concentrations (e.g., Betadine® )
• Chloroxylenol (Para-chloro-metaxylenol or PCMX) (0.5–3.75%), various other
concentrations (e.g., Dettol® )
• Ortho-phthalaldehyde (OPA)
• Triclosan (0.2-2%)
46
Table 5 The most frequently used Antiseptics, their microbiologic activities, potential use and effectiveness
47
8.3. When to Use Antiseptics
Use antiseptics
• before a clinical procedure involving skin, cervical, or vaginal preparation
• for surgical scrub
• for handwashing in high-risk situations, e.g., before, during and after
performing invasive procedures, touching a new-born or an
immunosuppressed patient
48
selecting an antiseptic solution.
Step 3: If the skin or external genital area is visibly soiled, gently wash it with soap
and clean water and dry the area before applying the antiseptic.
Step 4: Using dry, high-level disinfected forceps and new cotton or gauze squares
and antiseptic, thoroughly cleanse the skin. Work from the operative site
outward for several centimetres. (A circular motion from the centre out helps
to prevent recontamination of the operative site with local skin bacteria.)
Step 5: Allow the antiseptic enough time to be effective before beginning the
procedure. For example, when an iodophor is used, allow 2 minutes or wait
until the skin is visibly dry before proceeding, because the active agent (free
iodine) is only released slowly.
8.4.2. Instructions for Cervical or Vaginal Preparation
For cervical and vaginal antisepsis, prior to inserting a uterine elevator for mini
laparotomy or doing an endometrial biopsy, select an aqueous (water-based)
antiseptic, such as an iodophor (povidone-iodine) or 2-4% chlorhexidine gluconate
(e.g., Savlon if properly prepared). Do not use alcohols or alcohol-containing
preparations.
Step 1: Ask the patient about allergic reactions (e.g., to iodine preparations) before
selecting an antiseptic
Step 2: If the external genital area is visibly soiled, gently wash it with soap and clean
water and dry the area before applying the antiseptic.
Step 3: After inserting the speculum, apply antiseptic solution liberally to the cervix
and vagina (two times).
Step 4: If an iodophor is used, allow time (2 minutes) before proceeding.
49
• Establish a routine schedule for preparing new solutions and cleaning
reusable containers. (Solution is at increased risk of becoming contaminated).
“Do not “top off” antiseptic dispensers.
• Wash re-usable containers thoroughly with soap and clean water, and drip
dry before refilling.
8.6. Disinfectants
Disinfectants are chemicals that kill or inhibit all microorganisms except bacteria
endospores on inanimate objects.
8.6.1. Types of disinfectants
Table 6. Type of disinfectants
High-level disinfectants
• These are substances that kill all bacteria, viruses, fungi, and mycobacterium
tuberculosis. Some high-level disinfectants are also chemical sterilant and,
given sufficient time, will destroy bacterial endospores.
• Examples of disinfectants:
— sporicidin 2%
— chlorhexidine 4%, centrimide 5%
— hydrogen peroxide 6%
— chlorine 0.5%
Intermediate-level disinfectants
• Kill bacteria and most viruses
• Examples are: alcohols:
— isopropyl 60-70%
50
— ethanol 70-90%
— methylated spirit 60-90%
— iodines and iodophor 10% solutions
— povidone - iodine 2.5%
— formaldehyde 8%
**Note: Recommended for use on blood and other potentially infectious materials.
Small, non-lipid viruses, (e.g., enteroviruses) may be resistant. Used for some non-
critical items or devices, or on environmental surfaces.
Low-level disinfectants
• Kill some bacteria and some viruses and fungi, but do not kill tuberculosis-
causing microorganisms and bacterial endospores.
• Examples are:
— Hydrogen peroxide 3%
— Phenolics 1-2%
— Dettol
— Lysol 5%
— Carbolic acid 5%
51
— higher temperatures increase the killing power of most disinfectants
whereas lower temperatures slow the killing power
• Rough surfaces (having crevices, lumen, hinges) need a longer time for
disinfection
8.6.3. Choosing a Disinfection Method
Disinfectants chosen should be:
• Bactericidal not bacteriostatic
• Active against a wide range of microorganisms
• Not readily inactivated by organic matter (i.e. stable when in contact)
• Rapid activity
• Non-toxic
• Non-corrosive
• Non-damaging to equipment/substances treated
• Cost-effective and available
8.6.4. Guide to Use of Disinfectants (instructions)
• Check expiry date of the solution. The date should be clearly marked on the
container.
• Follow the manufacturer’s instructions AND ensure that the correct (optimum)
dilution is used.
• Disinfectant containers must be thoroughly cleaned or sterilized before refill
between uses. NEVER TOP UP!!
• Disinfectants must not be used to sterilize instruments or equipment (unless
specified in the disinfectant policy, e.g., endoscopes).
• Disinfectants should be supplied, preferably ready for use from the pharmacy
(new stocks to be supplied on receipt of empty containers). Do not discard
empty containers or use them to store other solutions. Chemicals can be
harmful when used in the wrong situations.
• Open containers of disinfectant should not be tolerated in any healthcare
environment.
• There is a serious risk of contamination with multiple antibiotic-resistant
bacteria such as Pseudomonas spp and spores.
• When disinfectants are indicated for use on surfaces, WIPE. (Do not wash,
bathe or flood-wash).
• Always thoroughly decontaminate, then clean articles before disinfection, i.e.,
remove any substance such as dirt and biological materials.
• The health facility pharmacy should ensure that:
- the containers are thoroughly cleansed, washed and dried
52
— the containers are clearly labelled with the type of contents, the in-use
dilution and the expiry date
— none of the disinfectants are exposed to inactivating substances, i.e., cork,
rubber caps or incompatible detergents
**Note: Disinfectants should be diluted by knowledgeable personnel in manageable
quantities, e.g., 5 litres or less. This will reduce waste. Partially filled containers must
not be left on the wards (prevent hoarding).
53
9.0. HEALTH CARE WASTE
The aim is to provide technical guidance on safe health care waste management
and to ensure compliance with HCWM regulations, standards, procedures and
specifications in order to protect public health and safeguard the environment.
9.1. Healthcare Waste Classification
Healthcare waste is classified mainly into two categories which are - Hazardous and
Non-hazardous waste.
9.1.1. Non-hazardous Waste
Non-hazardous waste is waste that has not been in contact with infectious agents,
hazardous chemicals or radioactive substances and does not pose a sharps hazard.
A significant proportion (about 85%) of all waste from health-care facilities is non-
hazardous waste and is usually similar in characteristics to municipal solid waste.
More than half of all non-hazardous waste from healthcare facility is paper,
cardboard and plastics, while the rest comprises discarded food, metal, glass,
textiles, plastics and wood.
9.1.2. Hazardous Health Care Waste
Hazardous waste is a waste that poses potential threat to public health and the
environment. They can be in the form of solid, liquid or gaseous. Hazardous waste is
classified into the following;
Infectious waste: is material suspected to contain pathogens (bacteria, viruses,
parasites or fungi) in sufficient concentration or quantity to cause disease in
susceptible hosts. This category includes: Waste contaminated with blood or other
body fluids;
highly infectious waste: Means all waste materials containing, blood, fluids with
viable biological agents from infected person or artificially cultivated in significant
elevated numbers; Waste from infected patients in isolation wards, cultures and
stocks; dishes, devices used to transfer, inoculate and mix cultures of infectious
agents. In case of notifiable highly infectious diseases ie. Viral Haemorrhagic fever,
such waste materials should follow extra treatment procedure.
Sharps: These are items that could cause cuts or puncture wounds and infections.
Sharps include needles, hypodermic needles, scalpels and other blades, knives,
infusion sets, saws, broken glass and pipettes. Whether or not they are infected, such
items are usually considered hazardous health-care waste and should be treated as if
they were potentially infected.
Pathological waste; These wastes consists of tissues, organs, body parts, blood,
body fluids and other waste from surgery and autopsies. It also includes human
foetuses and infected animal carcasses.
Pharmaceutical waste; These include expired, unused, spilt and contaminated
54
pharmaceutical products, prescribed and proprietary drugs, vaccines and blood sera
that are no longer required, and, due to their chemical or biological nature, need to
be disposed of carefully. The category also includes discarded items heavily
contaminated during the handling of pharmaceuticals, such as bottles, vials and
boxes containing pharmaceutical residues, gloves, masks and connecting tubes.
Genotoxic waste; These include certain cytostatic drugs, vomit, urine or faeces from
patients treated with cytostatic drugs, chemicals and radioactive material.
Chemical waste: These consist of discarded solid, liquid and gaseous chemicals; for
example, from diagnostic and experimental work and from cleaning and disinfecting
procedures. Chemical waste from health care is considered to be hazardous if it has
at least one of the following properties: toxic (harmful); corrosive (e.g. acids of pH <2
and bases of pH >12); flammable; reactive (explosive, water reactive, shock sensitive)
and oxidizing.
Wastes from materials with high heavy-metal contents represent a subcategory of
hazardous chemical waste and are usually highly toxic. Mercury and cadmium are
examples of highly toxic yet common substance in health-care facilities. Mercury
wastes are typically generated by spillage from broken clinical equipment
(thermometers and aneroid blood pressure equipment) and dental amalgam while
cadmium waste comes mainly from discarded batteries
Radioactive waste: These are materials contaminated with radionuclides. They are
produced as a result of procedures such as in vitro analysis of body tissue and fluid,
in vivo organ imaging and tumour localization, and various investigative and
therapeutic practices, which include liquids, gas and solids contaminated with
radionuclides whose ionizing radiations have genotoxic effects. The ionizing
radiations of interest in medicine include X-and y-rays as well as cx- and B- particles.
An important difference between these types of radiations is that X-rays tubes only
when generating equipment is switched on whereas y-rays, cx- and B- particles emit
radiations continuously. The type of radioactive material used n HCFs results in low
level radioactive waste and concerns mainly therapeutic and imaging investigation
activities where Cobalt 60 Co, Technetium 99mTc, iodine 1311 and iridium 192Ir are
most commonly used;
55
Recycling
• Healthcare facilities should use separate color coded containers placed at the
source of waste generation for recyclable materials.
• Healthcare facilities should practice effective waste segregation at the point
of generation to facilitate recycling of recyclable materials.
• All recyclable healthcare waste must be properly treated before taken out of
the healthcare facilities
Companied interested with recycling of medical materials must register for the
business by the Environmental Health Registration Board.
Re-use
• Surgical equipment and other items which are designed for reuse and are
sensitive to heat shall be sterilized by approved procedures.
• Operating and waste treatment costs should be reviewed periodically to
evaluate any fluctuations. Data shall be collected to allow comparisons
between HCF and to establish benchmarks.
56
Table 7. Colour cording
57
• All bin liners and /or containers of waste must be marked to identify the
unit/ward where the waste was generated
• Spare trolleys/wheeled bins shall be available in case of breakdowns and
maintenance
• The trolleys/ wheeled bins shall be cleaned and disinfected after every use.
• All waste bag seals should be in place and intact at the end of transportation.
• There should be separate, secured, storage rooms to maintain segregation
of:
— Radioactive waste
— Waste containing mercury
58
processes for the treatment of hazardous health-care waste that include thermal,
chemical, irradiation, biological and mechanical. The choice of treatment system
depends on local conditions and involves consideration of:
• Available resources including technical expertise
• Waste characteristics and volume
• Technical requirements for installation, operation and maintenance of the
treatment system
• Safety and environmental factors
• Cost considerations
With respect to special waste which include waste containing radioactive materials
and mercury shall require special treatment methods and receive special
supervision with technical expertise. Radioactive waste materials should be
managed under the supervision and recommendation by the Tanzania Atomic
Energy Commission. Mercury containing medical devices should be stored and
collected centrally for further disposal using internationally acceptable disposal
option.
59
Non-hazardous waste
• Non – hazardous waste shall be disposed off in public designated disposal
sites.
• In case there is no public disposal site the authority shall establish a
designated disposal site for non-hazardous that meet public health and
environmental requirement.
• Open burning is strictly not allowed for all types of waste
• The designated disposal site should be secured for unauthorised access and
fenced.
Hazardous waste disposal options
Hazardous waste must be treated before final disposal. The Ministry recommend the
following disposal option for various types of hazardous waste:
Pathological waste disposal:
• Every healthcare facility should have a standard designated placenta pit
within the facility premises.
• Other pathological waste must be treated, incinerated or buried.
• In case of human remain must be cremated or buried in public cemetery
Disposal of hazardous ash:
Fly ash and bottom ash from incineration is generally considered to be hazardous,
because of the possibility of having heavy metal content and containing dioxins and
furans.
• Hazardous ashes should be disposed of in sites centralized designed for
hazardous wastes,
• In the absence of designated disposal sites, the HCF should construct a
standard ash pit within or offsite the facility premises.
Sharp waste disposal
Even after sterilization, sharp waste may still pose physical risks. The HCF should do
the following;
• Sterilized sharp waste can be disposed of in safe sharp pits on the health
care facility premises or encapsulated by mixing waste with immobilizing
material like cement before disposal.
• In case recycling opportunity exist, sharp waste should be sterilized and
taken for recycling with licenced companies.
• Sharps can be incinerated where such high technology incinerator exist and
needles smelted and ash disposed of by burial method.
Disposal options in emergency situations
• The authority should take appropriate healthcare waste management
practices in line with the type of waste generated.
60
• Appropriate disposal options and procedures must be followed including
interim minimal disposal practices.
• Open dumping of boxes/bagged waste should be avoided.
Liquid waste management
There should be adequate, accessible and appropriate toilets for patients, staff,
caretakers and people with special needs. Wastewater produced should be treated
and disposed-off safely to protect workers and the environment.
• For the facilities with Onsite sanitation if involve the emptying of the sock
away pit the content should be treated in the sedimentation ponds
• For the facilities connected to sewerage system, the liquid waste from health
care facilities should be treated before discharged into sewerage or receiving
body.
• Note that sludge and sewage from health-care facilities generated by a basic
wastewater-management system should never be used for agricultural or
aquaculture purposes. Effluents should have met the required BOD
standards
• Liquid pharmaceuticals in vials (but not cytotoxic materials) can be crushed in
a closed bucket, mixed with sawdust, and the solid mass incinerated or
encapsulated.
Special waste classes
Chemical Wastes Containing Heavy Metals (mercury,), UPOPs, pharmaceutical
and cosmetic waste, radioactive waste, e- waste See HCWM guidelines for this
management and disposal
• Pharmaceutical waste and chemical waste should be stored until a safe
disposal option has been identified. (refer guideline from pharmaceutical
disposal)
61
10.0. WASH IN HEALTHCARE FACILITIES
WASH services provide for water availability and quality, presence of sanitation
facilities and availability of soap and water for handwashing. Adequate water,
sanitation and hygiene are essential components of providing basic health services.
The provision of WASH in health care facilities serves to prevent infections and
spread of disease, protect staff and patients, and uphold the dignity of vulnerable
populations including pregnant women and the disabled. Many health care facilities
in low resource settings have no WASH services, severely compromising the ability
to provide safe and people-centered care and presenting serious health risks to both
health care providers and those seeking treatment.

drying than other methods of hand hygiene since they dry hand more quickly and
remove bacteria and are less likely to lead to cross contamination. Paper towels also
offer the advantages of not needing electrical power where they are installed. In
order to make effective use of paper towels HCFs will have to do the following:
• Provide paper towel dispenser in all areas where hand washing facilities are
available
• Towel dispensers should be mounted such that access to them is free and
splashing or dripping onto adjacent wall and floor surfaces is minimized.
• Provide single‐use paper to turn off faucets so as to avoid hand
recontamination.
• Paper towels should be provided for use on the exit door hardware
• Waste bins for used towels should be located near the exit door.
• Avoid use of hot‐air dryers in any health care facility areas as warm air
currents dry hands slowly and can be used by only one individual at a time.
This results in queues and the temptation to dry hands on clothing.
• Provide lidded, lined, foot pedal‐operated waste bins, with waste bags, in
close proximity to each hand washing sink.
• Ensure that paper waste receptacles are a corrosion free material and wide
mouth design. Space should be allowed for the placement of waste bins in
close proximity to the hand.
69
10.3.4. Hand hygiene sink usage
The following precautions should be taken in order to ensure proper use of hand
hygiene sinks:
• Hand hygiene sinks should not be dedicated to any other purpose as each
sink will be used for a specified purpose
• Hand washing sinks should be cleaned on a regular basis
• Hand washing sinks should be regularly inspected to ensure they are
maintained in good condition.
• Paper towels and liquid soap should be provided at each hand washing sink.
• A current hand washing guide should be posted at each hand washing sink in
order promote correct washing methods.
10.3.5. Recommended hand washing facilities for HFs
Tables 12 and 13 provide the WHO recommended numbers of hand washing
facilities and their locations within the HF.1

• Linen and clean linen should be transported in different trolleys, bins, bags or
other transport means, including vans or other motor vehicles. If this is not
practicable, then trolleys, bins, bags or other transport means that were used
to transport soiled linen should be thoroughly cleaned/rinsed and
decontaminated with hospital-approved disinfectant and dried before being
used for transporting cleaned linen.
• Bags containing soiled linen should be handled carefully to avoid damage
and the release of possible contaminated aerosols into the air.
• In addition, workers should not carry wet, soiled linen close to their bodies
even if they are wearing a plastic or rubber apron.
10.6.3. Unloading and storage of soiled linen at laundry premises
• Sharps objects and other items such as incontinence wear should not be
inadvertently discarded into laundry bags
• Soiled linen when unloaded shall be stored in an area separated by a barrier
wall, from that where cleaned linen is stored or dispatched.
• Soiled linen shall be processed for washing within 24 hours.
— Linen must be handled with care to prevent contamination of your uniform
/clothes, equipment and environment. Segregate as follows:
Table 18. Segregation of linen
SAFE HANDLING OF USED LINEN
Which bag would you use for this?
Bag colour Linen type
YELLOW For infectious linen
Highly infectious linen: Fouled (soiled with blood or body
RED fluids) infectious, isolation and cytotoxic (attach a cytotoxic
label)
BLACK Non-infectious linen i.e. kitchen linen
• Sorting of soiled linen for washing is one of the most important operations in
the linen process.
• Sorting shall be according to soil quantity and nature of the linen and
segregation according to Highly infectious, Infectious and non- infectious
• Check if the process of inspecting and removing foreign, and, in some cases
dangerous, objects (e.g., sharps or broken glass), from soiled linen before
washing.
• This step is extremely important because soiled linen from the operating
room or clinic occasionally contains sharps (e.g., scalpels, sharp-tipped
scissors, hypodermic and suture needles and towel clips).
88
10.6.4. Laundering the linen
Pre- Washing of Linen
Linen which is heavily soiled with blood or other body fluids, or other fluids must be
rinsed with clean water dissected with appropriate dissecting before placing to the
machine
Thermal disinfection
• Soiled linen that is to be thermally disinfected shall be washed so that the
temperature of the load is maintained at a minimum of 70°C for not less than
25 minutes or 90°C for 10 minutes ( WHO, 2002).
• It is known that 60°C for 30 minutes kills HIV, 70°C for 10 minutes kills
vegetative microorganisms and 98°C for 2 minutes kills the Hepatitis B virus.
• If the thermal stability of the soiled linen is such that temperatures above
71°C are permissible, the time for disinfection may be appropriately reduced.
• The loads used in the machines should be as specified by the manufacturers’
recommendations. The proper function of the machines such as the time and
temperature of cycles should be checked regularly with calibrated
instruments.
• Any sensing elements should be placed so that they measure the actual
wash temperature (i.e., the temperature of the water in contact with the load).
• As it will take time for heat to penetrate the load, an allowance for mixing time
and load level shall be made to ensure that the load is maintained at the
correct temperature for the minimum time period.
• For low loading 4 minutes shall be allowed, and for high loading 8 minutes.
The minimum time/temperature combinations are therefore—
— 70°C maintained for not less than 25 minutes; minimum cycle time 14
minutes for low loading or 18 minutes for high loading; or
— 71°C maintained for not less than 3 minutes; minimum cycle time 7
minutes for low loading or 11 minutes for high loading.
• Steam or Gas may be used as heating elements.
Chemical disinfection
• Soiled linen that is heat sensitive and cannot be thermally disinfected shall be
washed using a wash cycle and appropriate chemicals registered with the
Tanzania Food and Drug Administration
• Wash used linen (sheets, cotton blankets) in hot water (70°C to 80°C) for 3
minutes and detergent, rinse and dry preferably in a dryer or in the sun.
• Heavy-duty washers/dryers are recommended for the hospital laundry.
Radioactive and radiation contaminated Linen
• Linen contaminated with radiation or any radioactive material shall be handled,
stored, transported, or otherwise disposed of in accordance with the laws,
89
standards and implementing rules and regulations according Tanzania Atomic
Energy Commission (TAEC )
• Some textile items (e.g., surgical drapes and reusable gowns) must be
sterilized before use and therefore require steam autoclaving after laundering.
• Use hygienically clean linen (i.e., laundered but not sterilized) in Neonatal
Intensive Care units.
• Burn unit linen need not be sterilized (unless specified by institution-specific
policy) but should at least be hygienically clean.
Hand Washing Linen
Step 1: Decontaminate linen in 0.05 chlorine solutions for 20 minutes to aid
cleaning and bactericidal action. This should be done after rinsing to
remove the blood, faeces, and vomitus
Step 2: Use warm water, Wash heavily soiled linen separately from non-soiled
linen
Step 3: Wash the entire item in water with liquid soap to remove all soils, even if
not visible. Add soap (a mild acid agent) to prevent yellowing of linen, if
desirable.
Step 4: Check the item for cleanliness. Rewash if it is dirty or stained.
Step 5: Rinse the item with clean water.
Detergent for hand washing linen
• Alkali – for soil removal and suspension
• Liquid surfactant or detergent – for removal of soil and prevents re- soilage
• Chlorine bleach/peroxide bleach – for disinfection and whitening
• Neutralizer – for souring/neutralizing after bleaching
• Fabric softener (optional)
The recommended wash cycle is as follows:
• Pre-wash
— Wetting (flushing)
— Pre-wash 1 (alkali)
— Prewash 2 (rinsing)
• Main wash (using detergent or surfactant) with minimum temperature and
wash time (see thermal requirements)
Rinsing cycle:
— Rinse 1 (with bleach)
— Rinse 2 (water)
— Rinse 3 (neutralizer and/or fabric softener)
• Water Extraction
• Separation
90
• Drying
• Tumble drying is preferred over other methods
Please note: Decontamination prior to washing is not necessary, unless linen is
heavily soiled and will be hand washed (note: repeat soaking of linen in chlorine,
even dilute solutions, will cause the fabric to deteriorate more quickly). The washing
process should have a disinfection cycle in which the temperature in the load is
either maintained at 65oC for at least ten minutes or 71oC for at least 3 minutes.
10.6.5. Storage of Clean Linen
It is highly recommended that healthcare facilities shall maintain at least 3 parts
stock level: 1 set in use, 1 set in the laundry, 1 set as reserve stock. Cleaned linen
should be stored in a clean, dry place in a manner that—
• is distinctly separated from soiled linen;
• Prevents contamination (e.g. by aerosols, dust, moisture and vermin); and
allows stock rotation, so that the oldest stock may be used first.
• Laundered linen should be stored on non-porous, clean shelves and, if
necessary, wrapped in a protective covering.
• Unused linen shall be reprocessed after 3 months.
• Packing and delivery
Depending on the size of the delivery and the nature of the items to be delivered,
cleaned linen which is to be returned to the client should be packed (either loose or
tied in bundles) into clean trolleys, bins, baskets and covered to prevent soilage; or
clean bags and securely fastened.
• Clean linen should be stored in closed cupboards, dedicated covered trolleys
or designated covered storage areas with:
• good ventilation
• adequate lighting
• Washed linen is placed in clean containers or on clean surfaces.
• Carts, marked trolleys or other leak proof containers are cleaned before taking
clean linen back to the wards.
• Clean linen is covered or wrapped during transportation.
91

Manager’s responsibilities
Managers need to be aware that the Food Safety Act and the regulations relating to
food safety legislation apply to all NHS premises and sites where food services are
provided. They apply to all areas where food or dinks are supplied by the Trust for
consumption by patients, staff and visitors. The standards of food hygiene require the
need to reflect the nature and activities of the food handling activities carried out in
the area.
Guidelines for kitchen services
• HCF kitchens should be well designed with good drainage system, ventilation,
easy to clean and should conform to standards and procedures for running
food premises;
• All windows should be screened to control flies and other insects;
• The food store should be clean and free from vectors;
• There should be a separate changing room for male and female kitchen staff;
• There should be adequate hand washing facilities with running water and
liquid soap;
• Food handlers should be screened after every six months (medical
examination, pre and regular);
• There should be smoke chimney to control air pollution;
• There should be adequate waste bins.
Where kitchen services are outsourced, there is a need for close supervision by
designated health officer. Conditions for outsourcing kitchen services should
97
necessarily include appropriate business registration and license, TFDA registration,
and acceptable environmental cleanliness of the business premises.

12.0. MORTUARY HYGIENE
Mortuary hygiene includes general cleaning and laundering, disinfection of essential
post-mortem/autopsy equipment, functioning refrigerators, availability of formalin,
appropriate personal protective equipment, vaccination, accidental exposure to blood
or body fluids and Healthcare waste management and washing facilities
99
• Chemical disinfection should be used only for items for which sterilization
and thermal disinfection are not suitable for example, items unable to be
immersed in water (thermal) or unable to withstand high-pressure gradients
(sterilization);
• Sufficient and appropriate disinfectant should be 0.5% chlorine solution for
routine mortuary work, embalming and post-mortems, then removed and
rinsed with distilled water before being dried and stored;
• Chemical disinfectant solutions should be discarded immediately after use;
• The container should have a close-fitting lid.
12.1.2. Other essential aspects in maintaining mortuary hygiene
In addition to the above guidelines other critical hygiene practices which each HCF
should ensure are properly addressed in the mortuary environment are outlined in
Table 19.

**NB: Preparation for deceased depends much on the cause of death
12.5.4. Assisting the Family at Household Level to Prepare the Body for Burial
• Assist family to follow personal hygienic measures when handling dead body:
– Avoid direct contact with blood or body fluids from the dead body;
– Put on gloves;
– Make sure any wound, cuts and abrasions are covered with bandages or
dressing;
– Observe hand hygiene;
– Make sure the body is clean and dry;
• Assist the family to prepare dead body for burial:
– Preparation of a deceased for a burial depend on the needs, personal life,
culture and religion of the of the deceased;
– During preparation the deceased should be treated with dignity and
respect;
– Regardless of what type of disposition that the family choose; bathing and
disinfecting the body is important;
• This is done not only for the safety of the funeral home staff, family and
friends, but also for dignity and respect of the deceased:
• A human body starts to change immediately after death occurs and bathing
and disinfecting are necessary:
109
– Prepare the body safely;
– Be aware of the family’s cultural practices and religious beliefs;
– Help the family understand why some practices cannot be done because
they place the family or others at risk for exposure;
– Counsel the family about why special steps need to be taken to protect
the family and community from illness;
– Identify a family member who has influence with the rest of the family and
who can make sure family members avoid dangerous practices such as
washing or touching the body without gloves;
– After bathing consider clothing and other mementos such as jewellery and
glasses;
– Options will vary depending on religious beliefs;
• Simple garments or particular outfits:
• May use clothes previously worn by the individual:
• When it comes to jewellery and mementos, such as wedding rings, glasses,
tie clips, etc. can be removed before the final disposition takes place:
• These items can be for temporary viewing purposes or they can be left with
the individual indefinitely:
• The final step is preparing the body for private or public viewing:
• Environmental control:
– Advise the family to buy disinfectant such as house hold sodium hypo
chloride (Jik);
– Assist the family on disposing all used materials;
– Make sure that all linen contaminated with blood or body fluids are soaked
in a fresh prepared household bleach for 30 minutes before washing.
12.5.5. Educating Relatives on Self-Protection when Contacting an Infectious
Deceased
Diseases that can be transmitted as a result of improper handling of an infectious
deceased:
• Hepatitis B;
• Hepatitis C;
• Cholera;
• Ebola;
• Anthrax;
• Meningococcal meningitis;
• Rift Valley Fever;
• Yellow fever.
Categories of Deceased Based on the Risk of Infection
There are two categories infectious deceased namely:
110
• Infectious deceased are those who died due to one of the following diseases;
– Human Immunodeficiency Virus infection (HIV);
– Hepatitis C;
– Meningococcal meningitis;
– Severe Acute Respiratory Syndrome (SARS);
– Avian influenza;
– Cholera;
– Rabies.
• Highly infectious deceased are those who died due to one of the following
diseases
– Anthrax;
– Plague;
– Ebola;
– Viral haemorrhagic fevers;
– Rift valley fever;
– The risks of infection can occur at any stage of handling and disposal of
human remains, this includes:
· Initial collection of remains;
· Transport of remains from initial collection point;
· Storage of remains prior to burial or cremation;
· Hygienic preparation or laying out;
· Post-mortem examination;
· Embalming;
· Laundering, cleaning instruments and disposal of waste used by a
deceased;
· Exhumation.
Methods of Protecting Self and Contacts of Infectious Deceased
• Adopt all safety standards for the handling of deceased because not all
cases of infection will have been identified before death;
• Adhering to standard precautions is the single most important element in
preventing the spread of infection from the deceased individual;
• Standard precautions include hand hygiene, wearing of personal protective
equipment, and careful handling of sharp instruments;
• For infectious deceased: use gloves, water resistant gown/ plastic apron, and
surgical mask. Use goggles or face shield to protect eyes, if there may be
splashes;
111
• For Very infectious deceased: Use water resistant gown/ plastic apron,
surgical mask, eye protection (goggles or face shield), double gloves, shoe
covers / boots;
• The deceased from the health facility must be transported in a sealed coffin;
• During ritual/religious preparation discourage viewing, touching and
preparation of the body by the family;
• Burial should take place as soon as possible to minimize the risk of
spreading the infection;
• Dispose the contaminated valueless material used by deceased by burning,
burying or throw in pit latrine;
• Disinfect valuable materials;
• Wash hands immediately after handling deceased or his/her belonging;
• Avoid direct contact with blood or body fluids from the deceased;
• Make sure any wounds, cuts and abrasions, are covered with waterproof
bandages or dressings;
• Do not smoke, drink or eat during handling of deceased;
• Do not touch the eyes, mouth or nose after handling infectious deceased;
• Avoid sharps injury, both in the course of examination of deceased and
afterwards in dealing with waste disposal and decontamination.
Educating Contacts on Self Protection when Contacting an Infectious
Deceased
Assess relatives’ emotions to decide their readiness to receive education
• Identify a family member who has influence with the rest of the family and
who can make sure family members avoid dangerous practices such as
washing or touching the body;
• Counsel the family about why special steps need to be taken to protect the
family and community from illness;
• Make sure the community leaders understand the importance of hand-
washing, decontamination of surfaces, careful laundering of clothes, bedding,
and other home infection prevention and control measures;
• Educate the relatives on protecting themselves from infectious dead body
and you will concentrate on the following:
– Hand washing immediately after handling dead body or his/her belonging;
– Use of gloves and plastic aprons;
– Importance of transporting dead body in a sealed coffin;
– Discourage viewing, touching and preparation of the body by the
family/mourners;
– Avoid contact with the blood and body fluids;
112
– Burial should take place as soon as possible to minimize the risk of
spreading the infection;
– Disposal of contaminated valueless material used by deceased by burning,
burying or throw in pit latrine;
– Disinfecting valuable materials.
• Accidental exposure to blood or body fluids
– In case of percutaneous injury or mucocutaneous exposure to blood or
body fluids of the dead body, the injured or exposed areas should be
washed with copious amount of water;
– All incidents of percutaneous or mucocutaneous exposure should be
reported to the supervisor;
– The injured person should immediately seek medical advice for proper
wound care and post-exposure management;
113
13.0. POST-EXPOSURE PROPHYLAXIS
Post-exposure prophylaxis is generally understood to mean the medical response to
prevent the transmission of blood-borne pathogens, including HIV, after exposure to
blood and other body fluids (WHO 2007). For more details refers the PEP guidelines.
Occupational Non-Occupational
Health care workers Victims of sexual assault
People who share needles or sharps (e.g.,
intravenous drug users, females who have
Emergency rescuers
undergone genital mutilation, and males who have
undergone unsafe circumcision procedures)
Waste disposal workers Individuals who have consensual sex
Law enforcement
Victims of human bites
personnel
117
13.2. Risk Classification associated with different types of Non-Occupational
Exposures to Blood and other Body Fluids
For non-occupational exposures, such as injuries or accidents that involve contact of
blood and other body fluids to skin, the risk categorization is similar to that for
occupational exposures, as presented in Table 23. However, for other types of non-
occupational exposures, the table below summarizes the risk classification.
Table 23. Risk Classification Associated with Different Types of Non-
Occupational Exposures
Risk Classification Types of Exposures
High-Risk Exposures • Unsafe receptive and inserted vaginal or anal
(Non-occupational post- intercourse
exposure prophylaxis • Rape or assault involving multiple perpetrators
should be recommended) • Rape or assault involving anal penetration
• Rape or assault in which there is obvious trauma to
the genital areas
• Rape or assault in which one of the perpetrators is
known to be HIV-positive
• Sharing of needles in intravenous drug users (who
never shared needles)
• Condom spillage or breakage during consensual
sex
• Rape or assault with no obvious trauma to genital
areas
• Injuries with exposure to blood or other potentially
• Infected fluids from a source person known to have
symptomatic HIV infection, AIDS, high viral load,
unknown HIV status (including needle sticks with a
hollow-bore needle, human bites, accidents), or is
in a window period.
• Injury in which source person has drug-resistant
HIV strain
Low-Risk Exposures • Oral-vaginal contact (receptive or insertive)
(Non-occupational post- • Oral-anal contact (receptive or insertive)
exposure prophylaxis • Receptive penile-oral contact with or without
should be recommended) ejaculation
• Insertive penile-oral contact with or without
ejaculation
• Rape or assault involving vaginal or mouth
• penetration (with no obvious injuries/trauma)
• Bite from a person with visible bleeding in the
mouth that causes bleeding in the exposed person
118
Risk Classification Types of Exposures
• Injuries resulting from trauma cases involving mass
• casualties--when there is significant cross-
contamination with blood and other body fluids (e.g.
motor traffic accidents)
• Injury in which source has asymptomatic HIV
infection or known low viral load (< 15000 RNA
copies/mL), in the absence of other risks (e.g., high
risks)
• Below is a list of factors that increase risk for the
above exposure events:
• Source person is known to be HIV-infected with
high viral load
• Source person is in a window period
• An oral mucosa that is not intact (e.g., oral lesions,
gingivitis, wounds)
• Oral mucosa is not intact (e.g., oral lesions,
gingivitis, wounds) --for oral sex exposure
• Lack of male circumcision, Cervical ectopy
• Blood exposure--it is important to note that blood
exposure can be minimal and therefore not
recognized by exposed person. If the exposed
person reports frank blood exposure, PEP would
be indicated
• Presence of genital ulcer disease or other STIs
• Lack of condom use
No Risk • Kissing
(Non-occupational post- • Oral-to-oral contact without mucosal damage
exposure prophylaxis not (mouth- to-mouth resuscitation)
warranted) • Human bites not involving blood
• Exposure to solid-bore needles or sharps not in
recent contact with blood
• Mutual masturbation without skin breakdown or
blood exposure
120
14.0. INFECTION PREVENTION AND CONTROL PRACTICE IN THE
OPERATING DEPARTMENT
The following guidelines are recommended for operating department staff when
invasive procedures are carried out, thereby protecting both patients and staff. Every
procedure carried out in the operating department should be assessed in terms of
blood or body fluid loss, and precautions taken accordingly.
Operating room
Operating theatre is a room specifically for use by the anaesthesia and surgical
teams and must be not used for other purpose.
Operating room requires:
• Good lighting and ventilation;
• Dedicated equipment for procedures;
• Equipment to monitor patients as required procedure;
• Drugs and other consumable for routine and emergence use.
Ensure that standard operating procedures are established for the correct use of the
Operating Room (OR) and all staff is trained to follow them: ·
• Keep all doors to the OR closed, except as needed for the passage of
equipment, personnel and the patient; ·
• Store some sutures and extra equipment in the OR to decrease the need for
people to enter and leave the OR during a case; ·
• Keep to a minimum the number of people allowed to enter the OR, especially
after an operation has started; ·
• Keep OR uncluttered and easy to clean; · Between cases, clean and disinfect
the table and instrument surfaces; ·
• At the end of each day, clean the OR: start at the top and continue to the floor,
including all furniture, overhead equipment and lights, use a liquid
disinfectant at a dilution recommended by the manufacturer;
• Sterilize all surgical instruments and supplies after use and store them
protected and ready for the next use.
121
and exits. There should be no thoroughfare through the Operating Theatre.
14.1.1. Walls and Ceiling
It is recommended that all surface materials should be hard, nonporous, fire resistant,
waterproof, stain proof, seamless and easy to clean. In addition, the corners of the
walls and the floor should be coved (round) and smooth for easy cleaning. Washable
epoxy resin paint for the walls is ideal, because it lasts a long time and can withstand
a daily washing programme. Cheaper paint has a tendency to break off and may fall
in an open surgical wound.
Tiles are generally not recommended as these are difficult to clean and collect dust
easily.
The walls and ceiling often are used to mount essential devices and equipment to
reduce crowding of the floor area therefore the walls must be solid and robust
enough to carry the weight of equipment. The ceiling may be used for mounting an
operating microscope, or an electrosurgical unit in addition to the operating light.
The walls must be fitted with outlets for oxygen, other medical gases and vacuum,
and where possible, an anaesthetic gas scavenging system should be fitted at floor
level. There is also a need to fit multiple electric outlets on the walls.
14.1.2. Floors
Floors should be smooth, continuous without cracks and breaks, made of materials
that will reduce static and should not endanger the safety of personnel.
The surface of the floor shall provide a path of moderate electrical conductivity
between all persons and equipment making contact with the floor to prevent the
accumulation of dangerous electrostatic charges.
The floor covering should be specified, such as continuous thick and tough vinyl, and
the manufacturer’s guidelines for cleaning and maintaining the floor must be
available in the cleaning policy.
The floor covering should be curved up the wall to 2.5 cm, thus ensuring that edges
are coved and easier to clean than right angled floors.
The floor surface must be suitably hard, nonporous and appropriate for frequent
cleaning and there should be no cracks. The floors should have a nonslip surface, to
prevent staff from slipping and injuring themselves. When floors are being cleaned, a
warning sign “wet floor” should be put up to warn the personnel.
14.1.3. Doors
Ideally, sliding or swing doors (self-closing) should be used in the Operating Theatre.
Sliding doors are recommended which must remain closed at all times, particularly
during an operation because the microbial count in the air rises every time doors
swing open from either direction.
122
There must be a clear glass viewing window in the door to prevent frequent opening
and closing of the door. The doors of the Operating Theatre will require baffle plates
to balance the airflows.
14.1.4. Lighting
Most Operating Theatre lights are white fluorescent because they cast minimal
shadow. Lighting should be evenly distributed throughout the room. The anaesthetist
must also have sufficient light.
The overhead operating light must:
• Be near daylight in colour and free of shadow;
• Give contrast to the depth and relationship of all anatomic structures. The
light may be equipped with an intensity control mechanism. The surgeon may
ask for more light when needed therefore a reserve light should be available
(e.g. a mobile operation light);
• Provide the diameter light pattern of a focus appropriate for the size of the
incision. These are adjusted with controls mounted on the light fixture;
• Be freely adjustable to any position or angle. Most overhead operating lights
are ceiling mounted on mobile fixtures. It can be positioned so that light is
directed into a single incision or two concurrent operative sites. e) Be spark-
proof where anaesthetic gases are used;
• Produce minimum heat to prevent injury to exposed tissues, to ensure the
comfort of the sterile team, and to minimize airborne micro-organisms;
• Be easily cleaned. Tracks recessed within the ceiling virtually eliminate dust
accumulation. Suspension-mounted tracks (booms) or a centrally mounted
fixture must have smooth surfaces easily accessible for cleaning.
A source of light from a circuit separate from the usual supply must be available for
use in case of power failure. In case one of the bulbs is not working, it should be
replaced as soon as possible, to provide sufficient lighting at all times during an
operation. NO oil, for example liquid paraffin, should be put on the operating light.
14.1.5. Ventilation
The ventilating system in the Operating Theatre must be mechanical ventilation,
supplied from an independent air handling unit (AHU) which ensures a controlled,
filtered, clean air supply. Air changes and circulation provide fresh air and prevent
accumulation of anaesthetic gases in the room.
Different modes of ventilation in Operating Theatre
There are usually two types of Operating Theatres. The Conventional Operating
Theatre is where 20-24 Air Change Rate (ACH) are delivered via mechanical
ventilation ducted into the room and removed via an exhaust system. This is the
more common type of ventilation available for conventional OTs for general surgery.
123
The second type of Operating Theatre is the ultra-clean or laminar flow Operating
Theatre. Here, 80% of extremely clean air is re-circulated via a canopy above the
operating area, and this unidirectional airflow can be up to 300 m/s (meters per
second) forming a curtain of air. This type of Operating Theatre is used for ultra-
clean operations like implant surgery.
Wall mounted or floor standing air conditioners are not considered appropriate for
providing clean air in a sterile environment, they only cool the air and are strongly
discouraged.
Fans are also strictly discouraged.
The filters clog up easily with dust which comes in directly from the outside and need
frequent changing. They do not remove stale air from the Operating Theatre which
increases the risk of infection.
14.1.6. Air flows
In the Operating Theatre there should always be positive pressure which enters the
Operating Theatre suite in the preparation or layup room, to ensure safety of the
surgical instruments when the trolleys are being laid up for surgical procedures. The
Layup and Operating Theatres should have the highest positive air pressure which
flows outwards to the scrub areas, and sub sterile rooms.
Positive pressure forces air out of the room. Air-conditioning units may be a source
of micro-organisms that pass through the filters. These must be changed at regular
intervals to prevent this and the ducts must be cleaned regularly according to the
manufacturer’s recommendations.
If air conditioners must be used, the position of the air-conditioning units should be
determined in consultation with the hospital engineers, surgeons, infection
prevention and control persons and other relevant cadres. Wall mounted air
conditioners (which do not regulate the contamination of the delivered air) should be
replaced by conventional airflow systems.
Temperature and Humidity
The temperature should be maintained at 21 +/- 3 degrees Celsius inside the OT all
the time with corresponding relative humidity between 50 to 60%. Appropriate
devices to monitor and display these conditions inside the OT may be installed.
Moisture provides a relatively conductive medium, allowing static to leak to earth as
fast as it is generated. Sparks form more readily with low humidity and fires are a
potential hazard.
Gas Scavenging System for Anaesthetic Explosive Gases
In most countries an anaesthetic gas scavenging system is put in place to avoid
major explosions. Since most anaesthetic gases are heavy they sink to the bottom
and there is a danger of fire or explosion should a spark be produced. The latter can
124
happen if the humidity is below 45% or with diathermy machines.
14.2.1. Unrestricted Area (a point through which staff, patients, and materials
enter the surgical unit)
Unrestricted areas need no special traffic flow. This area is the entrance from the
main corridor and is isolated from other areas of the surgical unit. This is the point
through which staff, patients and materials enter the surgical unit.
Post or display signs in each area to clearly indicate the appropriate environmental
control and surgical attire. Is equired.to have clear instructions to internal and
external customers.
14.2.2. Transition zone (where staff put on surgical attire)
This area consists primarily of dressing rooms and lockers. It is where staff put on
surgical attire that allows them to move from unrestricted to semi restricted or
restricted areas in the surgical unit. Only authorized staff should enter this area.
14.2.3. Semi-restricted area
A peripheral area of the surgical unit that includes preoperative and recovery rooms,
storage space for sterile and HLD items, and corridors leading to the restricted area.
Semi- restricted areas should allow only authorized staff and patients. Activities (e.g.,
instrument processing and storage) for the operating room occur here:
125
• Set and display rules and protocols of procedural area;
• Limit traffic to authorized staff and patients at all times;
• Have a work area for processing of clean instruments. Have storage space
for clean and sterile or high-level disinfected;
• supplies with enclosed shelves to minimize dust and debris collecting on
stored items;
• Note: Flip-flops or sandals should not be worn as they provide no protection
from dropped sharps;
• Have doors limiting access to the restricted area of the surgical unit;
• Staff should wear clean closed shoes that will protect their feet from fluids
and dropped items also should wear surgical attire and a cap;
• Everybody who enters into the semi-restricted area should wear surgical
attire.
14.2.4. Restricted area (the operating room and scrub sinks)
Restricted areas should allow authorized staff and patients only.
• This area consists of the operating room(s) and scrub sink areas;
• Limit traffic to authorized staff and patients at all times;
• Keep the door closed at all times, except during movement of staff, patients,
supplies and equipment;
• Scrubbed staff must wear full surgical attire and cover head and facial hair
with a cap and mask;
• Staff should wear clean, closed shoes that will protect their feet from fluids
and dropped items;
• Masks are required when sterile supplies are open and scrubbed staff are
operating.
• Patients entering the surgical unit should wear clean gowns or be covered
with clean linen, and have their hair covered;
• Patients do not need to wear masks during transport (unless they require
airborne precautions).
126
• Footwear should be antistatic and washable, and should be worn only in the
theatre department if possible. Shoes should be fully enclosed to provide
protection from spillages and accidentally dropped equipment. Each staff
member is responsible for cleaning their own shoes;
• Hair should be completely covered by a disposable or washable hat, this
should be donned before scrubs to prevent contamination of clean scrubs by
staff hair;
• Jewellery cannot only harbour bacteria, but also be a hazard in theatres;
• Plain wedding bands are permitted, although it is recommended that they are
removed before hand antisepsis (scrubbing) wherever possible;
• Earrings should not be worn, as they could potentially fall into a wound;
• Fingernails should be kept clean, short and free from nail polish;
• Short nails are less likely to puncture gloves or harm a patient during
transfer;
• False nails should not be worn as these have been shown to harbour micro-
organisms, even after hand washing, and can inhibit effective hand washing;
• Theatre staff with open cuts, wounds or skin breaks should cover these with
a waterproof dressing;
• If staff have ongoing skin conditions such as eczema or similar, an
Occupational Health Department referral should be considered before
participation in exposure prone procedures;
• Personal hygiene must be of a high standard;
• All visitors to the theatre department must report to reception staff or the
theatre co-ordinator prior to entering any restricted area;
• All people entering the theatre (staff and non-staff) will be required to comply
to the dress code of the theatre;
• All theatre clothes including hats and masks must be removed prior to
leaving the theatre department, and shoes changed if visibly stained.
• Theatre attires should not be worn in unrestricted areas.
14.3.1. Hand Preparation & Attire for Scrub Staff
127
• Soap and water alone are not considered to be acceptable for surgical hand
antisepsis, as soap has no anti-microbial properties;
• Soap can be used if staff also use an alcohol solution or gel afterwards;
• Hand washing should take place for a minimum of 2 minutes;
• Scrub brushes are not recommended for use on the skin as they can lead to
skin damage and an increase in skin cell shedding;
• Hands should be held higher than elbows, so that the water drains away from
the hands, and should be rinsed from fingertips to elbows using water flow
only;
• Vigorous shaking of the hands to dispel water should be avoided;
• Splashing of surgical attire should be avoided as wet clothing can
compromise the protection offered by a gown;
• Unless proceeding directly from one case to the next, hand antisepsis should
be the same as for the initial scrub;
• Alcohol hand rub gels can be used between cases, when following one case
directly with another, unless hands are visibly soiled;
• Double gloving is recommended for both staff and patient safety for every
procedure, especially if staff are involved with procedures which involve
sawing, drilling or wiring;
• Surgical gowns are supplied in different sizing options and resilience to liquid
strike through;
• Other PPE should be worn as indicated by the risk of body fluid splashes.
These might include masks with or without visors/goggles to protect the
wearers face from splashes etc.;
• Lead aprons should be worn for all procedures where the use of X-ray is
anticipated;
• Goggles are provided when procedures include the use of lasers and should
be worn to protect the eyes.
128
• To prevent disruption of airflows and minimize the risk of cross infection staff
must restrict their movement in and out of each theatre environment;
• Any visitors to the theatre department must report to reception staff or the
theatre co-ordinator/in charge prior to entering any semi-restricted or
restricted area. They must dress surgical attire;
• To maximise the ventilation, all doors should remain closed when not in use
as this helps to maintain the air pressure, temperature and humidity for that
theatre;
• If it is necessary to visit another theatre, staff must remove PPE and wash
hands before leaving the theatre.
129
• Theatre bacterial & fungal sterility check should be done at least quarterly;
• Theatre environment and equipment should be cleaned with detergent
and disinfected.
• If chlorine solution is used then this needs to be rinsed off equipment
afterwards. Chlorine is unsuitable for some surfaces depending on its
component, therefore, health personnel should check manufacturers’
guidelines;
• Alcohol hand rub gel should not be used to decontaminate hands if there is
visible body fluid or contaminants. Staff must wash hands using soap and
water and apply alcohol hand rub gel in addition.
14.5.1. Cleaning & Use of Endoscopes
• After use of all endoscopes should be flushed through with one litre of water
to ensure there is no blockage to hamper sterilisation. These are then
dismantled, soaked in OPA 0.3% solution for 12minutes or according to the
manufacturer’s guideline.
14.5.2. Before surgical procedures
Prepare the following containers or bucket:
• Place a clean, covered container filled with clean water or enzymatic
detergent or non-chlorine disinfectant for cleaning of used instruments;
• A container of 0.5% chlorine for surface use;
• A container of 0.05% chlorine for linen for soaking infected linen.
Use other locally available and approved disinfectant decontamination of instruments
and other items.
Prepare three standard colour coded waste bin or leak proof plastic bag:
• One waste bin for storage of contaminated waste items (cotton gauze, old
dressings);
• Second bin for none contaminated (food remains, papers, water bottle);
• Third bin for highly contaminated waste (Placenta, blood and body tissues);
• Place a puncture-resistant container or safety box for the safe disposal of
sharps (e.g., suture needles, hypodermic needles and syringes, and
disposable scalpel blades) at the point of use but without contaminating the
sterile field;
• Place a leak proof, covered waste container for soiled linen away from sterile
items;
• Organize all items in theatre according to the working flow well labelled easy
to see, take and return (practice of 5S-KAIZEN-TQM approach);
130
• Organize tables, Mayo and ring stands side by side in an area away from the
traffic patterns and at least 45 cm (18 inches) from walls, cabinets and other
non-sterile surfaces;
• Place a clean sheet, a lift sheet and arm board cover on the operating room
bed;
• Check and set up suction, oxygen and anaesthesia equipment;
• Place supplies and packages that are ready to open on the tables, not on the
floor;
• Mayo stand and other non-sterile surfaces that are to be used during the
procedure should be covered with a sterile draper.
14.5.3. During surgical procedures
• Limit the number of staff entering the operating room only to those necessary
to perform the procedure and to patients;
• Make the surgical team self-sufficient so that outside help is not required;
• Keep the doors closed at all times, except during movement of staff, patients,
supplies and equipment;
• Keep the number of people and their movement to a minimum; the numbers
of microorganisms increase with activity;
• Keep talking to a minimum in the sterile field;
• Scrubbed staff should wear full surgical attire, including:
– Sterile surgical gowns on top of the scrub suit;
– A clean surgical cap that covers the head;
– Clean boots that protect the feet from fluids or dropped items;
– Wear surgical gloves, protective eye wear and mask covering the mouth,
nose and any facial hair;
– Wear face shield and plastic or goggles, plastic or rubber apron;
– Scrubbed staff should keep their arms and hands within the operative
field at all times and touch only sterile items or areas;
• Non-scrubbed staff should:
– Stay at the periphery of the operating room;
– Keep their distance from sterile areas;
– Not lean or reach over the operative field.

132
• Remove waste, soiled linen, soiled instruments and equipment, and leak
proof, covered waste container. (Be sure that these items do not renter the
restricted area.)
**Note: Never store instruments and other items in the operating room. Controls
movements of staff and the use of surgical attire which might increase chance of
infection as one move from unrestricted to restricted areas. Staff with respiratory or
skin infections or uncovered open sores should never be allowed to work in any area
of the surgical unit unless they can use appropriate protective gear. Display a
signboard in Swahili to limit the entry of unauthorized persons might work in some
facilities.
• Cleaning of all theatre furniture and equipment should take place at the end
of each operation list;
• Operating tables should be thoroughly cleaned and should be raised to their
full height to enable bases be thoroughly cleaned, then lowered again
afterwards.
14.6.2. Pre-planned Annual Cleaning & Maintenance (PPM)
• The operating room and accompanying rooms, i.e. anaesthetic room, prep
area etc. should be kept free of unnecessary equipment & clutter to facilitate
cleaning;
• Theatres should be free of visible dust;
• Storage of sterile equipment & consumables should be above waist level;
133
• Ventilation grilles should not be obstructed or occluded;
• Storage of consumables, supplies etc should be kept to a minimum in theatre,
and stock should be rotated to ensure there is no build- up of dust or bio-
burden;
• Theatres should be kept in a good state of repair. Any chipped paintwork,
continuous tiling or defects in floors or fabrics should be reported and dealt
with promptly.
14.6.4. Eating & Drinking by Staff in the theatre environment
• All food and drink should be consumed in appropriate areas only e.g. staff
coffee room.
• Hands should be washed with soap and water before returning to the theatre.
134
PART III: PROCESSES IN INFECTION PREVENTION AND CONTROL
136
16.0. CENTRAL STERILIZATION SUPPLY DEPARTMENT (CSSD)
The CSSD is the area where instruments and equipment are processed, and where
staff should be specially trained in handling, processing and storing instruments,
equipment and other clean, sterile or high-level disinfected items.
Structure of a central sterile services department/unit
The CSSD may be laid out in various configurations, depending on the size of the
population it serves, the number of operations it has to support, and the distance
from the service delivery to the point of use. It is advisable to choose the most
effective and appropriate layout based level of health facility, workload, staffing and
financial resources, but the basic functioning and integrity of the department must
not be compromised.
Advantages of CSSD:
• Efficiency: staff of all levels, knowledge and experience are maximized, thus
improving productivity;
• Economy: the initial outlay for capital equipment is high, but the processing
can be used optimally and improve cost effectiveness;
• Safety: can be upgraded and modernized, which will improve patient safety;
• Validation: this allows processing systems to be standardized, resulting in
improved Quality Assurance programme.
**NOTE: Ideally, CSSDs should be divided into areas that are physically separated with a
clear unidirectional movement.
workflow from dirty to clean.
137
There should be physical barriers, such as walls or double-door (pass-through)
sterilizers between the packing and the sterile storage area. There should be no
crossover of staff or devices unless specifically indicated, such as returning devices
that have not been properly cleaned. The space shall be designed to ensure a one-
way movement of staff and devices from contaminated to clean areas to minimize
the bioburden and particulate contamination.
Basic criteria are:
• Entrance and corridors (public areas);
• Gowning points for staff to don PPE prior to entering work areas;
• Dirty area receiving of used medical devices (dirty area);
• Inspection, assembly and packing [IAP] (clean);
• Sterilization area (sterilizers);
• Sterile store (cooling and short-term storage);
• Administration and staff rest and changing areas (essential to be away from
work areas);
• Storage for devices, chemicals and packaging stores (raw material and SSD
products);
Smaller specialized sterilization units
Smaller units may be decentralized and could be located in operating theatres,
endoscopy units or diagnostic departments. A theatre sterile services unit (TSSU) is
no longer accepted practice unless there are specific reasons, such as remotely
located operating theatre suites with limited devices, surgical trays, processing
equipment and resources, including transportation. However, if such smaller units do
exist, these must be well controlled with complete systems of validation in place as in
larger SSDs.
Layout of smaller sterilization units
138
The CSSD is considered a semi-restricted area, so all the recommendations for
traffic patterns and surgical attire described above should be followed. A CSSD
consists of four areas:
1. The “dirty” receiving/clean-up area;
2. The “clean” work area;
3. The cleaning equipment storage area;
4. The sterile or high-level disinfected storage area.
The function and equipment requirements for the four areas of a typical CSSD are
summarized below
1. “Dirty” Receiving/Clean-up Area
In this area soiled items are received, disassembled and washed, rinsed and dried.
The “dirty” receiving/clean-up area should have:
• A receiving counter;
• Two sinks if possible (one for cleaning and one for rinsing) with a clean
water supply;
• A clean equipment counter for drying.
2. “Clean” Work Area
In the clean work area, cleaned items are:
• Inspected for flaws or damage;
• Packaged (if indicated), and either sterilized or high-level disinfected;
• Sent for storage as packaged or air dried and placed in a sterile or high-
level disinfected container.
The clean work area should have:
• A large work table;
• Shelves for holding clean and packaged items;
• A high-pressure steam sterilizer, a dry-heat oven, a steamer or a boiler.
3. Cleaning Equipment Storage Area:
Store clean equipment in this area on shelves (preferably enclosed) for storing clean
equipment; have an office desk for record keeping. CSSD staff should enter the
through this area.
4. Sterile or High-Level Disinfected Storage Area:
• Store sterilized packs and covered sterile or high-level disinfected containers
in this area. This area should be separated from the central sterile supply area.
Limit access to the storage area and/or store items in closed cabinets or
shelves.
• Enclosed shelves or cabinets are preferred as they protect packs and
containers from dust and debris. Open shelves are acceptable if the area has
limited access, and housekeeping and ventilation practices are controlled.
139
• Keep the storage area clean, dry, dust-free and lint-free by following a regular
housekeeping schedule.
• Packs and containers with sterile or high-level disinfected items should be
stored 20 to 25 cm (8 to 10 inches) off the floor, 45 to 50 cm (18 to 20 inches)
from the ceiling and 15 to 20 cm (6 to 8 inches) from an outside wall
• Do not use cardboard boxes for storage (Cardboard boxes shed dust and
debris and may harbour insects).
Date and rotate the supplies (first in, first out). This process serves as a reminder
that the package is susceptible to contamination and conserves storage space, but it
does not guarantee sterility.
Packs will remain sterile as long as the integrity of the package is maintained.
Sterile or high-level disinfected containers remain so until they are opened.
• Dispense sterile and high-level disinfected articles from this area.
**NOTE: Medical devices processed outside the CSSD cannot be controlled and are
considered unsafe unless these processes are under the supervision of highly-trained staff
of a similar caliber to those in the CSSD.
140
16.3. Handling and Transporting Instruments and Other Items before Use
• Keep clean and high-level disinfected or sterile instruments and other items
separate from soiled equipment and waste items. Do not transport or store
these items together.
• Transport high-level disinfected and sterile instruments and other items to the
procedure or operating room in a closed container with a cover to prevent
contamination.
• Remove supplies from all shipping cartons and boxes before bringing such
supplies into the procedure room, the operating room or the clean work area
of the CSSD.
• (Shipping boxes shed dust and harbour insects that may contaminate these
areas).
• Transport soiled supplies and instruments to the receiving/clean-up area of
the CSSD in leak-proof, covered waste containers.
• Transport contaminated waste to the disposal site in leak-proof, covered
waste containers.
141
17.0. PROCESSING INSTRUMENTS AND EQUIPMENTS
Health worker need to consider the following issues to prevent the risk of transferring
infection from instruments and equipment, which depends on the following factors:
• The presence of micro-organisms, the number and virulence of these
organisms;
• The type of procedure that has been performed (invasive or non-invasive),
and
• The body site where the instrument that has been used (penetrating the
mucosal or skin tissue or used on intact skin).
143
High-Level Disinfection Boil or steam:
• Boil or steam lead on for 20 minutes
• Chemical: soak in 0.3% ortho-phthalaldehyde (Cidex OPA) for 12 minutes
144
**Note: When bleach powder is used: the resulting chlorine solution is likely to be
cloudy (milky)

• For dry powders, read x grams per liter (example: Calcium hypochlorite – 7.1
grams mixed with 1 liter water).
• Use boiled water when preparing a 0.1% chlorine solution for HLD because
tap water contains microscopic organic matter that inactivates chlorine.
• Sodium dichloroisocyanurate
• Chloramine releases chlorine at a slower rate than does hypochlorite. Before
using the solution be sure the tablet is completely dissolved
Adapted from World Health Organization, 1989.
WHO Recommendations
Soaking of instruments in 0.5% chlorine solution or any other disinfectant
before cleaning is not recommended for the following reasons:
• It may damage/corrode the metallic instruments
• The disinfectant may be inactivated by blood and body fluids, which could
become a source of microbial contamination and formation of biofilm
• Transportation of contaminated items soaked in chemical disinfectant to the
decontamination area may pose a risk to health-care workers and result in
inappropriate handling and accidental damage
• May contribute to the development of antimicrobial resistance to disinfectants

• Water-soluble lubricant is recommended (Karl Zsort or Olympus instrument
oil);
• Never use steel wool or abrasive powders on stainless steel instruments;
• Never label surgical instruments with masking tape;
• Staining/spotting of instruments can be caused by moisture or water;
• When instruments do stain in spite of all good care taken they can be cleaned
by using a commercially available rust and stain remover.
New instruments
• All new instruments are supplied without lubrication. It is recommended that
all be carefully washed and dried and any moving part lubricated;
• Whenever cleaning, regardless of method, keep ratchets unlocked and box
joints open;
• When instruments are no longer new, avoid as far as possible contact
between stainless steel instruments and any of the following substances:
barium chloride, aluminium chloride, bromide and iodine containing
compounds.
Manual cleaning of soiled instruments and equipment
• When an operation is in progress do not drop instruments into a holding
solution of disinfectant. If the instruments are not cleaned first, disinfectants
such as chlorine act as fixatives of any organic material present, making it
difficult to remove;
• Instruments should not be soaked in saline, as they will become pitted;
• Dilute detergent properly as per supplier’s directions;
• Completely dismantle all items and leave instruments open;
• Use warm water, detergent and a hard brush to completely remove the blood,
tissue, food and other residue, paying special attention to small teeth of
instruments and joints;
• Finally rinse with clean water to remove traces of detergent;
• Dry properly. Failure to remove water from trapped areas will cause corrosion;
• Consider the item contaminated when packaging is torn, damaged, wet,
dropped on the floor and when the expiry date has passed.
147
**Note: Sterilization kills all microorganisms, including bacterial endospores; it is
preferable to HLD for instruments and other items that will come in contact with the
bloodstream or tissues under the skin. If sterilization is not available, HLD is the only
acceptable alternative.
HLD can be performed by:
• Boiling;
• Soaking in chemicals;
• Steaming.
17.5.1. High-Level Disinfection by boiling
Step 1: Clean all items to be boiled:
• Open all hinged items and disassemble those with sliding or multiple parts;
• Completely submerge all items in the water in the pot or boiler;
• Place any bowls and containers upright, not upside-down, and fill with water.
Step 2: Cover the pot or close the lid on the boiler and bring the water to a gentle,
rolling boil.
Step 3: When the water comes to a rolling boil, start timing for 20 minutes;
• Use a timer to make sure to record the time that boiling begins;
• From this point on, do not add or remove any water and do not add any items
to the post or boiler.
Step 4: Lower the heat to keep the water at a gentle, rolling boil.
**Note: If the water boils too vigorously, it will evaporate, and the items may
become damaged if they bounce around the container and hit the sidewalls
and other items being boiled. Lower heat also saves fuel or electricity.
Step 5: After 20 minutes, remove the items using dry, HLD pickups (lifters, cheatle
forceps). Place the items on an HLD tray or in an HLD container away from
insects and dust.
Step 6: Allow to air-dry before use or storage
Step 7: Use items immediately or keep them in a covered, sterile or HLD container
for up to one week.
**Note: Never leave boiled items in water that has stopped boiling; they can
become contaminated as the water cools down.
148
17.5.2. High-Level Disinfection by Steaming
After instruments and other items have been decontaminated and thoroughly
cleaned, they are ready for HLD by steaming.
Step 1: Place instruments, plastic MVA cannulas and other items in one of the
steamer pans with holes in the bottom. To make removal from the pan easier,
do not overfill the pan.
Step 2: Repeat this process until up to three steamer pans have been filled. Stack
the filled steamer pans on top of a bottom pan containing water for boiling. A
second empty pan without holes should be placed on the counter next to the
heat source.
Step 3: Place a lid on the top pan and bring the water to a full rolling boil. (When
water only simmers, very little steam is formed and the temperature may not
get high enough to kill microorganisms).
Step 4: When steam begins to come out between the pans and the lid, start the timer
or note the time on a clock and record the time in the HLD log.
Step 5: Steam items for 20 minutes.
Step 6: Remove the top steamer pan and put the lid on the pan that was below it (the
pan now on top). Gently shake excess water from the pan just removed.
Step 7: Put the pan just removed onto the empty pan. Repeat until all pans are
restacked on this empty pan and the top pan is covered with the lid. (This
step allows the items to cool and dry without becoming contaminated).
Step 8: Allow items to air dry in the steamer pans (1 to 2 hours) before using.
Step 9: Using a high-level disinfected forceps, transfer the dry items to a dry, high-
level disinfected container with a tight-fitting cover. Instruments and other
items can also be stored in the stacked and covered steamer pans as long
as a bottom pan (no holes) is used.
Note: Both boiling and steaming share some advantages and disadvantages
over chemical high-level disinfection, which is the only other method of HLD.
17.5.3. High-Level Disinfection by Chemicals
Step 1: Clean, and thoroughly dry all instruments and other items to be processed.
Water from wet items will dilute the chemical solution, thereby reducing its
effectiveness.
Step 2: When using OPA solution: Prepare the 0.3% solution according to the
manufacturer’s instructions. Ideally, an indicator strip should be used each
time the solution is used to determine if the solution is still effective. After
preparing the solution, place in a clean container with a lid. Mark the
container with the date the solution was prepared and the date it expires. If
using unboiled water, as described. Fresh solution should be made each day
149
or more often if the solution becomes cloudy. Put the solution in a clean
container with a lid.
**Note: Use chlorine solution with boiled water and not tap water
Step 3: Open all hinged items and disassemble those with sliding or multiple parts.
The solution must contact all surfaces in order for HLD to be achieved.
Completely submerge all items in the solution. All parts of the items should
be under the surface of the solution. Place any bowls and containers upright,
not upside-down, and fill with the solution.
Step 4: Cover the container and allow the items to soak for 20 minutes. Do not add
or remove any instruments or other items once timing has begun.
Step 5: Remove the items from the solution using dry, HLD pickups (lifters, cheatle
forceps).
Step 6: Rinse thoroughly with sterile or boiled water to remove the residue that
chemicals leave on items. This residue is toxic to skin and tissue.
Step 7: Place the items on an HLD tray or in an HLD container and allow to air dry
before use or storage. Use items immediately or keep in a covered, dry HLD
container and use within one week.
17.6. Sterilization
Sterilization protects patients by eliminating all micro-organisms (bacteria, viruses,
fungi, and parasites), including bacterial endospores, from instruments and other
items. Sterilization is recommended for instruments and other items that will come in
contact with the bloodstream or tissues under the skin, as well as on draped and
some surgical attire. Sterilization can be performed using:
• dry heat (oven)
• high pressure steam (autoclaving)
• soaking in chemicals (cold sterilization)
Heat (autoclaving/steam and dry heat) is the most effective method of sterilization
and reliable if monitored carefully. It is also cheaper than chemical methods. It
should be considered first for all medical equipment that can withstand heat.
Chemicals are the alternative where heat cannot be used, e.g., ethylene oxide and
glutaraldehyde.
150
17.6.1. Sterilization by Dry Heat
Time/Temperature:
• 1 hour at 170 degrees C (340 degrees F);
• 2 hours at 160 degrees C (320 degrees F);
• 21/2 hours at 150 degrees C (300 degrees F);
• 3 hours at 140 degrees C (285 degrees F).

18.0. HOUSEKEEPING
Housekeeping refers to the general cleaning of hospitals and clinics, including the
floors, walls, and certain types of equipment, furniture and other surface Health care
environments are important reservoirs for infectious microorganism and are critical to
address. Targeted prevention effort can reduce the rate of some HAI by 70%.
Healthcare personnel play a critical role in targeted prevention efforts.
Microbe Survival
Survival of select pathogen on environmental surfaces
Pathogen Survival Time
Bacteria
C. difficile ≥ 1 year
MRSA 7 days – 7 months
VRE 5 days – 4 months
Viruses
Hepatitis B ≥ 1 month
Norovirus 8 hours – 7 days
Kramer A, et al. BMC Infect Dis. 2006;6:130.
Housekeeping refers to the general cleaning of hospitals and clinics, including the
floors, walls, and certain types of equipment, furniture and other surfaces. Cleaning
entails the removal of dust, soil, and microbial contaminants on environmental
surfaces since they are the potential source of healthcare associated infection.
Effective and efficient cleaning methods and schedules are, therefore, necessary to
maintain a clean and healthy environment in healthcare settings.
The purposes of general housekeeping are to:
• To reduce the number of micro-organisms that may come into contact with the
health workers, clients or members of the community who visit the facility;
• To reduces the risk of incidence through prevention of accidents such as falls
and so on;
• To ensures a pleasant atmosphere for both health workers and patients/clients.
In high-risk areas where heavy contamination is expected, such as toilets and
latrines, or for blood or body fluid spills, collect all blood or body fluid spill, then wipe
with 0.5% chlorine solution. 1% phenol should be added to the cleaning solution
(SEARO 1988). Using a disinfectant in addition to soap and water is also
recommended in other high-risk areas such as operating rooms, pre- and
postoperative recovery areas and intensive care units (ICUs).
153
If the purpose of housekeeping as stated above is to be achieved, it is important that
housekeeping staff be trained to perform their assigned tasks and are supervised on
a regular basis.
As part of their training, it is important that housekeeping staff:
18.1. Definitions
Housekeeping
• Housekeeping Is an art of maintaining healthcare facility and management of
duties involved in the running of a household, such
as cleaning, cooking, home maintenance and laundry.
Cleaning
• This is the process which removes foreign materials (such as soil, blood, body
fluids and micro-organisms) from an object. Usually running water and soap
are applied;
• Accumulation of dust, soil, and microbial contaminants on environmental
surfaces is both aesthetically displeasing and a potential source of hospital
acquired infection infections;
• Effective cleaning methods and schedules are, therefore, necessary to
maintain a clean and healthy environment in healthcare settings.
Cleaning solution
• Any combination of soap (or detergent) and water, with or without a chemical
disinfectant, used to wash or wipe down environment surfaces such as floors,
chairs, benches, walls and ceilings.
Disinfectants
• Chemicals that destroy or inactivate microorganisms. Disinfectants are
classified as low-, intermediate- or high-level depending on their ability to kill
or immobilize some (low- or intermediate-level) or all (high-level)
microorganisms (but not all spores).
• Phenols, chlorine or chlorine-containing compounds and QUATs are classes
of disinfectants frequently used to clean non-critical surfaces such as floors,
walls and furniture.
Disinfectant cleaning solution
• Disinfectant cleaning solution is products that are a combination of a
detergent (soap) and a chemical disinfectant. Not all detergents and
154
disinfectants are compatible. Several combinations are available commercially
or can be prepared, such as alkaline detergents with chlorine compounds,
alkaline detergents with quaternary ammonium compounds (QUATs) or other
nonionic surfactants, and acid detergents with iodophors.
Environmental controls
• Environmental controls are standards specifying procedures to be followed for
the routine care, cleaning and disinfection of environmental surfaces, beds,
bedrails, bedside equipment and other frequently touched surfaces.
Sanitizers
• Sanitizers include chemicals that reduce the number of bacterial contaminants
to safe levels on inanimate objects based on public health requirements (i.e.,
a chemical that kills 99.999% of the specific test bacteria in 30 seconds under
the conditions of the test).
Soaps and detergents (terms used interchangeably)
• These are cleaning products (, liquid, leaflet or powder) that lower surface
tension, thereby helping remove dirt, debris and transient microorganisms
from hands. Plain soaps require friction (scrubbing) to mechanically remove
microorganisms; antiseptic (antimicrobial) soaps kill or inhibit the growth of
most microorganisms.
General Principles for Cleaning Hospitals, Clinics and other Healthcare
• Scrubbing (frictional cleaning) is the best way to physically remove dirt, debris
and microorganisms.
• Cleaning is required prior to any disinfection process because dirt, debris and
other materials can decrease the effectiveness of many chemical disinfectants.
• Cleaning products should be selected on the basis of their use, efficacy, safety
and cost.
• Cleaning should always progress from the least soiled areas to the most soiled
areas and from high to low areas, so that the dirtiest areas and debris that falls
on the floor will be cleaned up last.
• Dry sweeping, mopping and dusting should be avoided to prevent dust, debris
and microorganisms from getting into the air and landing on clean surfaces.
Airborne fungal spores are especially important as they can cause fatal
infections in immunosuppressed patients (Arnow et al., 1991).
• Mixing (dilution) instructions should be followed when using disinfectants.
(Too much or too little water may reduce the effectiveness of disinfectants).
• Cleaning methods and written cleaning schedules should be based on the type
of surface, amount and type of soil present and the purpose of the area.
• Routine cleaning is necessary to maintain a standard of cleanliness.
155
• Schedules and procedures should be consistent and posted
157
Wet mopping is the most common and preferred method to clean floors.
• Single-bucket (basin) technique: One bucket of cleaning solution is used. The
solution must be changed when dirty. (The killing power of the cleaning
product decreases with the increased load of soil an organic material present);
• Double-bucket technique: Two different buckets are used, one containing a
cleaning solution and the other containing rinse water.
• The mop is always rinsed and wrung out before it is dipped into the cleaning
solution.
• The double-bucket technique extends the life of the cleaning solution (fewer
changes are required), saving both labour and material costs;
• Triple-bucket technique: The third bucket is used for wringing out the mop
before rinsing, which extends the life of the rinse water.
Flooding followed by wet vacuuming is recommended in the surgical suite, if possible.
This process eliminates mopping, thus minimizing the spread of microorganisms,
and increases the contact time of disinfectants with the surface to be cleaned. But it
is necessary to leave the floor wet for several minutes. (Flooding is best done at
night or at times when foot traffic is minimal).
Dusting is most commonly used for cleaning walls, ceiling, doors, windows,
furniture and other environmental surfaces.
• Clean cloth or mops are wetted with cleaning solution contained in a basin or
bucket;
158
• The double-bucket system minimizes the contamination of the cleaning
solution;
• Dry dusting should be avoided, and dust cloths and mops should never be
shaken to avoid the spread of microorganisms;
• Dusting should be performed in a systematic way, using a starting point as a
reference to ensure that all surfaces have been reached.
**Note: When doing high dusting (ceiling tiles and walls), check for stains that may
indicate possible leaks. (Leaks should be repaired as soon as possible because
moist ceiling tiles provide a reservoir for fungal growth).
Principles for Cleaning:
• Scrubbing is the best way to remove dirt and micro-organisms, hence always
use it;
• It is important to always wear gloves while cleaning, especially heavily
contaminated areas such as toilets and areas with blood and body fluids
spills;
• Use a damp cloth for walls and floors;
• Dry sweeping should be avoided as the particles spread dust, debris and
micro-organisms;
• Use separate equipment like cloths and brushes for cleaning high risk
environment and others for low risk environment;
• Change cleaning solutions when absolutely dirty;
• Clean and dry the mops, dusters, cloths and other cleaning equipment after
cleaning is over;
• When washing walls, wash from top to bottom and when cleaning surfaces
clean from less dirty to very dirty areas;
• When using disinfectants, follow the manufacturer’s instructions about diluting
the chemicals, their storage and disposal.

PART IV: PREVENTING INFECTIONS IN SPECIAL SETTINGS
19.0. PREVENTING NOSOCOMIAL INFECTIONS
Nosocomial infections, or hospital-acquired infections, are those that a patient
develops within 24 hours of admission in a hospital, or infections that a patient is
incubating at the time he or she comes to the hospital. Healthcare Associated
Infection are a significant problem throughout the world and are increasing (Alvarado
2000). Although the exact data for the transmission of Healthcare Associated
Infection in Tanzanian health facilities are yet to be determined, these infections are
important contributors to morbidity and mortality. Healthcare Associated Infection are
an important focus of infection prevention in all countries, but especially in
developing countries.
The most important Healthcare Associated Infection are:
• Maternal and new-born infections;
• Infections following surgery;
• Infections related to intravascular interventions;
• Urinary tract infections;
• Pneumonia;
• Infectious diarrhoea.
The organisms causing most Healthcare Associated Infection usually come from the
patient’s own body (endogenous flora). They also can come from contact with staff
(cross-contamination), contaminated instruments and needles, and the environment
(exogeneous flora). Key contributing factors are:
• Inadequate standards and practices for operating blood transfusion services;
• Increasing use of invasive medical devices (e.g., mechanical ventilators,
urinary catheters and central intravenous lines) without proper training or
laboratory support use of contaminated intravenous fluids, especially in
hospitals making their own IV solutions;
• Antibiotic resistance due to overuse of broad spectrum antibiotics;
• Unsafe and frequently unnecessary injections;
• Increasing numbers of people in healthcare facilities, overcrowding in wards
sharing beds;
• More frequent impaired immunity (age, illness and treatments);
• New microorganisms, such as HIV, SARS and Ebola.
164
death (Ponce-de-Leon, 1991). The impact of Healthcare Associated Infection takes
on even more significance in resource-poor countries, especially those affected most
by HIV/AIDS; recent findings strongly suggest that unsafe medical care may be an
important factor in transmitting HIV (Gisselquist et al., 2002).
Healthcare Associated Infection increase the cost of healthcare in the countries least
able to afford it through increased:
• Length of hospitalization;
• Treatment with expensive medications (e.g., antiretroviral drugs for HIV/AIDS
and antibiotics);
• Use of other services (e.g., laboratory tests, X-rays and transfusions).
167
• The medical staff should follow the standard prevention principles during the
diagnosis. They must wear surgical masks when contacting each patient and
implementing strict hand hygiene measures. When contacting a suspected or
confirmed patient, the medical staff must wear medical protective masks;
• The medical staff must be aware of the epidemiology and clinical features of
human infection with influenza A (H7N9) virus and are able to take immediate
isolation measures for the suspected or confirmed patients and timely report
every case. After a patient is transferred out, terminal disinfection should be
performed according to the Technical Specifications for Implementing
Disinfection in Hospitals;
• Medical staff must put on or take off protective equipment correctly as
required when entering or leaving a fever clinic;
• The patients’ caregivers and patients (if their conditions allow) must wear
surgical masks.
Emergency
• Triage system must be established. A contingency plan covering the transfer-
out and rescue of the critically ill patients should be established and updated,
and then strictly implemented;
• A specific isolation zone should be established to allow the in-site isolation
and management of the suspected/confirmed patients;
• The medical staff must carry out personal protection and hospital environment
management in strict accordance with the standard prevention principles;
• The diagnosis and treatment zones must have good ventilation conditions and
be cleaned and disinfected regularly.
General wards
• Contingency isolation rooms should be available in the general wards for the
isolation and management of the suspected/confirmed cases, and relevant
working policies and workflow should be established. Sufficient disinfection
facilities and personal protective equipment for managing acute respiratory
infections should be available in these rooms;
• When a suspected or confirmed case is found in the ward, the relevant
contingency plans and workflow must be initiated immediately to provide
timely and effective isolation and secure for the patient;
• The suspected or confirmed patient should be managed and cared by a
special team of medical staff. Medical staff who are not directly involved in the
management should be restricted from entering the ward. If condition allows,
the patients should be treated in negative pressure rooms or transferred to a
special hospital with appropriate isolation or treatment capabilities.
168
• After a patient is transferred out, terminal disinfection should be performed
according to the Technical Specifications for Implementing Disinfection in
Hospitals.
Special wards for patients with suspected or confirmed human infection with
influenza A (H7N9) virus:
• The building layout and workflow design should meet the relevant
requirements of the Best Medical Management Practices for Isolation;
• All the suspected or confirmed patients should be immediately isolated, and
the suspects and cases should be placed in separated rooms. The suspects
should be isolated in a single room. The etiologically confirmed patients with
the same disease type can be placed in the same room;
• According to the transmission pathways of influenza A (H7N9) virus, contact
or droplet precautions should be taken in addition to the standard preventive
measures. These measures may include:
– Medical staff must put on or take off protective equipment correctly
according to the Best Medical Management Practices for Isolation when
entering or leaving an isolation ward;
– In principle, the patients’ activities should be restricted within the isolation
wards. If a patient needs to leave the isolation ward or isolation zone,
he/she must take appropriate protective measures (e.g., wearing a
surgical mask) to avoid cross-infection;
– Stethoscope, thermometer, blood pressure monitors, and other medical
devices for the suspects and cases must be used in a patient-specific
manner. If the medical devices are not used in a patient-specific manner,
they must be thoroughly cleaned and disinfected;
– The visiting policies must be strictly implemented. In principle, no
caregiver is allowed.
Protection of medical staff
• The medical staff should take contact and droplet precautions based on the
transmission pathways of the infection in accordance with the standard
protection principles;
• The personal protective equipment used by the medical staff meet the
relevant criteria issued by the Chinese government;
• The medical staff must timely perform hand hygiene before and after each
contact with the patients in accordance with the Standard for Hand Hygiene
for Healthcare Workers;
• The medical staff must take appropriate protective measures according to the
level of risk for infection:
169
– The medical staff must wear non-sterile gloves when contacting blood,
other body fluids, secretions, excretions, and vomit of the patients and the
contaminated items and wash their hands after taking off the gloves;
– When there is a risk of spraying/splattering of blood, other body fluids,
excretions or secretions, the medical staff must wear surgical masks (or
respirators), goggles, and gowns;
– When performing endotracheal intubation for the suspects or cases, the
medical staff must wear medical protective masks, goggles, and gowns;
– The individual protective equipment such as surgical masks, medical
protective masks, goggles, and gowns that have been contaminated by
the patients’ blood, other body fluids, and/or secretions must be timely
changed;
– The individual protective equipment should be properly put on or taken off.
After taking off the gloves or gowns, the medical staff must wash or
disinfect hands immediately;
– The medical staff must be protected from being accidently stabbed by
sharps;
– The used medical equipment and instrument must be properly cleaned
and disinfected according to the Technical Specifications for Implementing
Disinfection in Hospitals.
Patient management
• The suspects and cases must be timely isolated, and be specifically guided to
enter the isolation wards via the assigned route;
• If the condition allows, the patients must wear surgical masks. The patients
should be instructed to cover nose and mouth with a tissue when coughing or
sneezing. After contacting respiratory secretions, the patients must wash
hands with regular detergent or disinfect hands with hand disinfectant;
• After a patient is discharged or transferred out, terminal disinfection should be
performed according to the Technical Specifications for Implementing
Disinfection in Hospitals;
• The corpses of deceased patients must be timely handled. The corpse should
be bounded with a double-layer fabric, wrapped into a double-layer plastic bag,
and then sent directly by a special vehicle to a designated place for cremation.
If cremation is not feasible due to ethnic or religious concerns, the corpses
should be buried deep as required after having been handled as described
above. Contact Precautions:
• Contact precautions reduce the risk of transmission of organisms from an
infected or colonized patient through direct or indirect contact. They are
indicated for patients infected or colonized with enteric pathogens. Examples
include herpes simplex and haemorrhagic fever virus (Ebola) and multi-drug
(antibiotic) resistant bacteria;
170
• Use in addition to Standard Precautions for a patient known or suspected to
be infected or colonized with microorganisms transmitted by direct contact
with the patient or indirect contact with environmental surfaces or patient care
items.
171
20.0. PREVENTING MATERNAL AND NEWBORN INFECTIONS
Pregnant women in developing countries are at a much higher risk for acquiring
Healthcare Associated Infection following delivery than their counterparts in
developed countries. The rate of postoperative infection after Caesarean Section is
high (15 – 60%). With the emergence of HIV, up to 12% of pregnant women have
been found to be HIV sero positive. As a result pregnant women in developing
countries are at a higher risk for acquiring Healthcare Associated Infection following
delivery.
Other than maternal tetanus toxoid immunization during pregnancy, and treatment to
prevent congenital syphilis, few other preventive measures to protect the foetus and
new-born are routinely available. For example, with the exception of prenatal HIV
testing and antiretroviral treatment in a few countries, screening and treatment for
infectious diseases (e.g., gonorrhoea and Chlamydia) are not available because of
the cost and lack of laboratory capability.
20.1. Definitions
Endometritis
• Acute postpartum infection of the lining (endometrium) of the uterus with
extension into the smooth muscle wall (myometrium). Clinical features include
fever, usually developing on the first or second postpartum day, uterine
tenderness, lower abdominal pain and foul-smelling vaginal discharge (lochia).
Episiotomy
• Surgical cut made in the perineum just prior to delivery. The purpose is to
facilitate delivery of the presenting part and minimize the risk of injury to the
perineal area.
Intra-amniotic infection syndrome (IAIS) also referred to as amnionitis
orchorioamnionitis
• Acute detectable infection in the uterus and its contents (foetus, placenta and
amniotic fluid) during pregnancy. It is usually related to colonization of the
uterine cavity with organisms present in the cervix and vagina after prolonged
ruptured membranes and obstructed labour.
Invasive group B streptococcal sepsis
• Newborn infection characterized by bacteremia, pneumonia, meningitis and
death in up to 25% of infants with the infection. It occurs most commonly
following IAIS.
HealthCare Associated infection in newborns
• Infection occurring after birth but excluding those infections known to have
been transmitted across the placenta such as congenital syphilis,
172
cytomegalovirus, rubella, varicella (chicken pox) and the protozoan parasite,
Toxoplasmosis gondii.
HealthCare Associated infection in obstetrical patients
• Infection that is neither present nor incubating at the time the patient is
admitted to the hospital. Most urinary tract infections and endometritis are
nosocomial even though the causative organism may be endogenous (i.e.,
present in the maternal lower genital tract prior to delivery).
Septic pelvic thrombophlebitis
• Thrombosis (blockage) of the deep pelvic veins due to inflammation and blood
clots. Predisposing factors include caesarean section after prolonged labour,
premature rupture of membranes, difficult delivery (forceps or vacuum
extraction), anaemia and malnutrition.
20.2. Epidemiology
20.2.1. Maternal Infections
Caesarean section is the most important factor contributing to both the frequency
and severity of postpartum infection. Patients who have cesarean sections are at
least 10 times more likely to become infected than patients who deliver vaginally
(Minkoff and Schwarz, 1980).
Predisposing factors for wound infection; Intra-partum factors (factors during
delivery)
• Women who:
– Have bacterial vaginosis (Gardnerella vaginalis) isolated from the
endometrium.
– Have a Caesarean Section during the second stage of labour
• Maternal factors
– Diabetes mellitus
– Malnutrition
– Immunodeficiency
– Anaemia
– Infection of the foetal membranes (chorioamnionitis) diagnosed prior to
delivery (Mead 1993).
• Other obstetrical infections including:
– Nosocomial urinary tract infections
– Episiotomy infections
– Nosocomial pneumonia
– Septicemia
– Breast infection (mastitis) in postpartum nursing women
173
20.2.2. Foetal and Newborn Infections
Foetal and newborn infections are classified based on whether they were acquired in
utero (transplacentally), during passage through the birth canal (vertical
transmission) or in the neonatal period (i.e., during the first 28 days following birth).
Strictly speaking, only newborn infections acquired during passage through the birth
canal or in the neonatal period are considered nosocomial. Determining whether an
infection is nosocomial or was present or incubating prior to admission to the hospital
is extremely difficult – and often not useful.
20.3. Microbiology
20.3.1. Causes of Maternal Infections
Most postpartum infections are caused by endogenous flora – microorganisms that
are normally present in the genital tract but usually cause no disease until labour,
delivery or postpartum. Nearly 30 types bacteria have been identified as being
present in the lower genital tract (vulva, vagina and cervix) at any time (Faro 1990).
While some of these, including several fungi, are considered nonpathogenic under
most circumstances at least 20, including E. coli, Staphylococcus aureus, Proteus
mirabilis and Klebsiella pneumoniae, are pathogenic.
20.3.2. Colonization and Infection in Newborns
Most infants are delivered from a sterile environment inside the uterus. During and
after birth, however, they are rapidly exposed to numerous microorganisms that
colonize their skin, nasopharynx and gastrointestinal tract. Sick newborns, subjected
to multiple invasive procedures (e.g., endotracheal tubes or umbilical artery
catheters) may be colonized at multiple sites with numerous other organisms,
particularly gram-negative bacteria.
The skin of the newborn is a major initial site of bacterial colonization, particularly for
S. aureus, which is most often acquired from within the nursery rather than from the
mother.
Any break or cut in the skin provides an opportunity for infection to develop with this
pathogenic organism. Therefore, to minimize the risk of infection in the newborn
period, all sites must be cared for using aseptic technique.
Although severe infection in a full term infant is uncommon, when it occurs it often is
secondary to group B. streptococci, E. coli, Listeria monocytogenes, Citrobacter
diversus, salmonella, chlamydia, herpes simplex virus (HSV) or enteroviruses. All of
these organisms can be transmitted to other infants in the nursery on the hands of
hospital staff unless Standard Precautions are strictly followed, especially those for
handwashing (or use of antiseptic hand rub) and gloves.
174
20.4. Preventing Foetal and Newborn Infectious Diseases
Prevention against most foetal and newborn infectious diseases has been achieved
through improved maternal immunization, antenatal treatment of maternal conditions
and prophylactic use of medications, e.g., postnatal eye drops to prevent
conjunctivitis and, recently, the use of antiretroviral drugs to prevent mother-to-child
transmission of HIV.
Reducing the Risk of Maternal and Newborn Infections
To minimize the risk of exposure to HIV and other blood-borne viruses during labor,
childbirth and resuscitation of the baby, strict use of Standard Precautions, especially
hand washing and use of gloves, face shields and plastic or rubber aprons, is
mandatory.
Factors Increasing the Risk of Infection during Labor and Vaginal Childbirth
Vaginal deliveries are associated with a number of factors that increase a woman’s
risk of endometritis or urinary tract infection. These include:
• Prolonged ruptured membranes (more than 18 hours)
• Trauma to the birth canal (episiotomy, vaginal or perineal lacerations and
urethral tears)
• Manual removal of the placenta due to retained placenta or placental
fragments
• Prolonged labour
20.4.1. Decreasing the Risk of Infection during Vaginal Childbirth
Steps that can be taken to decrease the risk of maternal infection before and during
childbirth include:
Step 1: Make sure the following items are available:
• Two pairs of surgical gloves
• Pair of clean gloves for washing the perineum
• Basin of clean warm water, soap, a face cloth and clean dry towel
• Plastic or rubber apron and face shield (or a mask and goggles)
• Waterless, alcohol-based antiseptic hand rub or antiseptic solution (e.g., 2%
• Chlorhexidine gluconate or 10% povidone-iodine)
• High-level disinfected or sterile blunt scissors (Mayo)
• High-level disinfected or sterile cord clamp or cloth to tie off the cord
• Injectable oxytocin (with or without egormetrine)
• Sterile syringe and needle
• Sterile urinary catheter
• Package of gauze squares
175
• Clean basin for the placenta
• Clean drape or cloth for wrapping the baby
• Second Clean drape or cloth for wrapping the baby
• Clean perineal pads
• Light source (a flashlight or lamp) if needed
• Puncture-resistant sharps container (within arm’s reach if possible)
• Plastic bag or a leak-proof, covered waste container for disposal of
contaminated waste items.
Prior to Childbirth
Step 2: Wear protective equipment including a plastic or rubber apron and face
shield (or a mask and goggles) because splashing of blood and blood-tinged
amniotic fluid can be expected.
Step 3: Once the patient is positioned for childbirth, put examination gloves on both
hands and wash the perineal area (vulva, perineum, and anal region) with
soap and clean water.
• use a downward and backward motion when washing the perineal area so
that fecal organisms will not be introduced into the vagina
• clean the anal area last and place the washcloth or towel in a plastic container
• shaving perineal (pubic) hair prior to delivery is discouraged since it increases
the risk of infection (Landry and Kilpatrick, 1997)
Step 4: Immerse both gloved hands in 0.5% chlorine solution, remove gloves by
inverting, and place them in the plastic bag or leak-proof, covered waste
container.
Step 5: Thoroughly wash hands, especially between the fingers, and forearm up to
the elbows with soap and clean water and dry with a clean, dry towel or air
dry.
Step 6: Put sterile (or HLD) surgical gloves on both hands.
During Childbirth
If resuscitation of the infant is required, use a Dee Le mucus trap or mechanical
suction if available to avoid backflow of newborn secretions.
If manual removal of the placenta is required, use elbow length gloves if available,
or improvise by using a second pair of fingerless surgical gloves, which should be
used to avoid contaminating the forearm with blood.
176
After Childbirth
Step 7: Before removing gloves, put the placenta in the clean basin and place all
waste items (e.g., blood-stained gauze) in the plastic bag or leak-proof,
covered waste container.
Step 8: If an episiotomy or vaginal or perineal tears require surgical repair, use
forceps to hold suture needle and then place sharps (suture needles) in the
puncture-resistant sharps container.
177
20.6. Postpartum Care of the Mother following Caesarean Section
Minimizing the risk of nosocomial infection in mothers during the postpartum period
includes the following:
• Ensure urine is flowing and the urine collection system is intact;
• Follow the “Tips for Preventing Infections”;
• Remove the catheter as soon as possible within 24 hours.
178
21.0. PREVENTING SURGICAL SITE INFECTIONS
Despite improvements in operating room practices, instrument sterilization methods,
better surgical technique and the best efforts of infection prevention practitioners,
surgical site infections (SSIs) remain a major cause of Healthcare Associated
Infection and rates are increasing globally (Alvarado 2000).
To reduce the risk of nosocomial SSIs in developing countries, a systematic but
realistic approach must be applied with awareness that this risk is influenced by
characteristics of the patient, the operation, the healthcare staff and the hospital.
Among surgical patients, SSIs are the most common nosocomial infection,
accounting for about a third of all such infections. On average, having an SSI
increases a patient’s hospital stay by 7-10 days, with organ/space and deep
incisional SSIs accounting for the longest stays and highest costs.
Exogenous sources of SSI pathogens are occasionally responsible. These include
the following;
• Organisms from members of the surgical team (e.g., hands, nose or other
body parts);
• Contaminated surfaces in the operating room, even the air;
• Contaminated instruments, surgical gloves or other items used in the surgery.
• Exogenous organisms are primarily aerobic staphylococci or streptococci
species (with the exception of tetanus endospores).
21.1. Definitions
Surgical Site infections (SSI): Either an incisional or organ/space infection
occurring within 30 days after an operation or within 1 year if an implant is present.
Superficial SSI: involves only the incised body wall.
Organ/Space SSI: Any part of the body other than the incised body wall parts that
were opened or handled during an operation.
179
Class III – Contaminated
Open, fresh accidental wound or an operation with a major break(s) in aseptic
technique (e.g., open cardiac massage) or gross spillage from the GI tract. Also
included are incisions in which acute, non-purulent inflammation is found;
Class IV – Dirty or infected
Old wounds with dead tissue and those that involve existing clinical infection or a
perforated bowel, suggesting that the pathogens causing the postoperative infection
were present in the wound before the surgery.
21.3. Pathogenesis
By the end of an operation, bacteria and other microorganisms contaminate all
surgical wounds, but only a small number of patients actually develop a clinical
infection. Infection does not develop in most patients because their defence
mechanisms effectively eliminate the contaminating organisms at the surgical site.
Whether a potential infection occurs depends on several factors. The most important
include the following:
• Number of bacteria entering the wound;
• Type and virulence (ability to cause infection) of the bacteria;
• Host defence mechanisms (e.g., effectiveness of inflammatory response and
status of the immune system);
• External factors, such as being in the hospital several days before surgery or
the operation lasting more than 4 hours.
180
accompanied by decreased defence mechanisms, poor nutrition and anaemia.
**Note: When possible, the effects of conditions that might complicate surgical
recovery should be corrected or stabilized preoperatively.
Remember: Wash hands or use an antiseptic hand rub, before putting on gloves
and after taking them off to avoid exposure to blood and other potentially infected
body fluids and to decrease the risk of cross contamination.
182
22.0. PREVENTING INFECTIONS RELATED TO USE OF INTRAVASCULAR
DEVICES
The use of intravascular devices, both venous and arterial, to deliver sterile fluids,
medications and nutritional products, as well as for central monitoring of blood
pressure and other hemodynamic functions, has dramatically increased during the
past decade, creating a large population at risk for local and systemic blood stream
infections.
Intravascular devices inserted into the venous or arterial bloodstream bypass the
normal skin defence mechanism, and provide a way for microorganisms to enter the
bloodstream from:
• the device at the time of insertion;
• subsequent contamination of the device or attachments (e.g., tubing
connected to the blood monitoring apparatus or the fluids being administered);
• pathogens on the skin surrounding the insertion site;
22.1. Microbiology
Both gram-negative bacteria and staphylococci are primary causes of catheter-
related infection; however, with the advent of the HIV/AIDS epidemic, infections with
fungi are increasingly being reported (Jarvis and Hughes, 1993). Some
microorganisms, especially coagulase-negative Staphylococcus aureus and
pseudomonas and acinetobacter species, adhere to the fibrin film that forms on the
inside of catheters within days after insertion. As a consequence, infection with these
organisms is quite common, especially if the infection occurs within 10 days of
insertion (Raad et al., 1993). For devices left in place longer than 30 days (e.g.,
tunnelled CVCs), bloodstream infections are more likely due to the contamination of
the hub of the catheter, especially if frequent handling of the hub occurs (Schaberg,
Culver and Gaynes, 1991).
22.1.1. Risk Factors
Individual related factors:
• Burns;
• Surgical wounds;
• Malnutrition;
• Immuno compromises (by HIV/AIDS or chronic corticosteroid treatment).
Person-to-person contact-related factors:
• Cross-contamination with other infected areas of the patient’s body either by
the patient or on the hands of the health worker;
• Cross-contamination from another patient via the hands of the health worker;
183
• Cross-contamination from the patient when the health worker comes in
contact with the patient’s blood during insertion, care of the insertion site or
removal of the catheter;
• Poor insertion or dressing change technique.
Device-related factors:
Before insertion:
• Cracks in infusion bottles;
• Punctures in plastic containers;
• Contaminated infusion fluid or additives;
• Leaky IV administration sets with multiple connections;
• Non-sterile preparation of intravenous infusion fluid.
• During use:
• Multiple changes of IV fluid containers while using the same IV administration
set;
• Multiple injections and irrigations of the system;
• Central venous pressure measurement apparatus.
• Wash hands thoroughly with soap and running water before touching any of
the IV set components;
• Examination gloves should be put on just before touching the insertion site or
the hub of the needle or catheter;
• Wash hands with soap and running water after removing gloves.
22.2.2. Site Care and Dressings:
• If the site for inserting the catheter is dirty, wash it with soap and clean water
and dry it before applying the skin antiseptic;
• If using povidone-iodine (PVI) as the antiseptic agent, allow it to dry after
applying or wait at least 2 minutes before insertion;
• Transparent, adherent dressings allow inspection of the site;
• Dressings can be left in place for up to 72 hours if they are kept dry. (They
should be changed immediately if they get wet, soiled or loose);
• Gauze and tape dressings need to be changed if an inspection of the site is
necessary;
• The catheter or needle site should be gently palpated daily for tenderness;
184
• The insertion site should be inspected if the patient develops tenderness or
fever without an obvious cause (CDC and HICPAC 1996).
• For adults, hand veins are preferred over arm veins, and arm veins over leg
and foot veins. (Needles and catheters inserted in leg and foot veins are more
likely to cause inflammation at the insertion site, or phlebitis);
• Changing sites at 72 – 96 hours will reduce phlebitis and local infection.
“Cannulas” are preferred over steel needles because they are less apt to
perforate the vein with movement;
• If only short-term (less than 48 hours) IV infusion is planned, straight or
butterfly needles are less irritating than plastic catheters and have lower rates
of infection;
• Because straight and butterfly needles frequently infiltrate, they should not be
used with solutions that could cause tissue necrosis.
22.3.2. Central Venous Catheters
Site Care and Dressings:
• If the site for inserting the catheter is dirty, wash it with soap and clean water
and dry it before applying the skin antiseptic;
• Use 2% chlorhexidine gluconate, 10% PVI or 60 – 90% alcohol for skin
preparation;
• Insertion should be done using full barrier precautions (sterile gloves, gown,
mask and site drape) in a procedure area, not at the bedside.
22.3.3. Changing Fluids and Infusion Sets
185
22.4. Insertion, Maintenance and Removal of Peripheral Venous Lines
22.4.1. Insertion Procedure for Establishing an Intravenous (IV) Line
Step 1: Make sure all items are available:
• IV solution bag or bottle;
• Straight or butterfly needle or plastic catheter (steel needle inserter covered
with soft plastic tubing that is left in place after the needle is withdrawn);
• Antiseptic solution (e.g., 2% chlorhexidine, 60 – 90% alcohol or 10%;
• povidone–iodine) and sterile or clean gauze squares (2 x 2 or cotton swabs);
• Surgical tape or transparent dressing;
• Clean tourniquet;
• Clean arm board;
• Towel to place under patient’s hand or forearm;
• IV pole (drip stand);
• Clean pair of single-use examination gloves;
• Basin of clean warm water, soap, face cloth and clean dry towel;
• Plastic bag or leak-proof, covered waste container for disposal of
contaminated items.
Step 2: Explain the procedure to the patient;
Step 3: Prior to starting the procedure, identify the best vein(s) for inserting IV needle
or plastic catheter;
Step 4: If the venepuncture site is dirty, first wash it with soap and clean water and
dry with a clean cloth before applying a skin antiseptic;
Step 5: Wash hands with soap and clean water and dry with a clean dry towel;
Step 6: Check the IV solution (bottle or plastic bag) to be sure it is the correct
infusion;
Step 7: Open the infusion set and assemble the parts using aseptic technique (e.g.,
don’t touch the ends of tubing);
Step 8: Insert the infusion set into solution bottle or bag;
• Remove the protective cover from the solution bottle or bag without touching
the opening.
• Remove the protective cap covering the insertion spike without touching the
spike and insert the spike into the stopper of the IV bottle or opening of the IV
bag.
Step 9: Fill the infusion tubing.
• Compress the drip chamber and release.
186
• Remove the protective cover of the IV tubing and release the roller clamp to
allow fluid to fill the tubing; close the roller clamp and replace the protective
cover. (Check to be sure tubing is clear of air bubbles.)
Step 10: Put clean examination gloves on both hands.
Step 11: Cleanse insertion site with antiseptic solution using a circular motion
outward from the insertion site. (If using povidone-iodine, allow it to dry,
about 2 minutes, because it releases free iodine, the active antiseptic agent,
slowly).
Step 12: Insert the needle or catheter with the bevel up using the dominant hand.
Look for blood return in the tubing and carefully advance the needle or
butterfly until the hub rests at the veinpuncture site. (With catheters, after
getting blood return, advance the needle about 1 cm (1/2 inch), withdraw the
inner insertion needle and then advance the plastic catheter to the hub.)
Step 13: While stabilizing the needle or catheter, release the tourniquet and roller
clamp to permit a rate of flow sufficient to keep the IV line open.
Step 14: Secure the needle or catheter by placing a narrow piece of tape (1 cm or
1/2 inch) under the hub with the adhesive side up and cross tape it over the
hub. Then place a second piece of narrow tape directly across the hub of the
needle or catheter.
Step 15: Place a sterile gauze square (2 x 2) over the veinpuncture site and secure it
with two pieces of tape. (Alternatively, place a transparent dressing over the
venepuncture site.)
Step 16: Prior to removing gloves, place any blood-contaminated waste items (cotton
or gauze squares) in a plastic bag or leak-proof, covered waste container.
Step 17: Remove gloves by inverting and place them in a plastic bag or waste
container.
Step 18: Wash hands or use antiseptic hand rub as above.
Step 19: Secure the wrist or forearm to the arm board by applying two strips of tape
directly across wrist or forearm. (To minimize discomfort when removing the
arm board, attach a shorter piece of tape to the longer piece, adhesive side
to adhesive side, that will cover the wrist or arm.)
Step 20: Adjust the flow rate to the correct number of drips per minute.
22.4.2. Maintenance of IV Lines
Step 1: Check the line every 8 hours for phlebitis or evidence of infection;
Step 2: Change the infusion site at 72-96 hours, when practical, to reduce the risk of
phlebitis and local infection;
Step 3: The infusion (administration) sets (including the piggybacks) should be
changed whenever they are damaged and at 72 hours routinely;
187
Step 4: If the tubing becomes disconnected, wipe the hub of the needle or the plastic
catheter with 60 – 90% alcohol and connect to a new infusion set;
Step 5: Mark the site on the plaster with time and date of insertion of the I.V. line and
make sure the site is dry.
22.4.3. Removal Procedure
Step 1: Make sure all items are available:
• Clean pair of examination gloves;
• Antiseptic solution (2% chlorhexidene gluconate, 60-90% alcohol or 10%
povidone-iodine);
• Gauze squares (2x2) and surgical tape or a sterile, wide (1 inch) band aid;
• Puncture-resistant sharps container within arm’s reach if a straight or butterfly
needle was used;
• Plastic bag or leak-proof, covered waste container for disposing of the
contaminated items;
Step 2: Wash hands with soap and running water.
Step 3: Stop the infusion by closing the roller clamp.
Step 4: Put clean examination gloves on both hands.
Step 5: Remove the dressing and discard it in a plastic bag or leak-proof, covered
waste container.
Step 6: Check the patient’s hand or wrist for phlebitis or evidence of an infection (an
area of swelling, redness, warmth and tenderness of the skin around the site
where the intravascular catheter comes out of the skin, the exit site). If
phlebitis is associated with other signs of infection, such as fever or pus
coming from the exit site, it is classified as a clinical exit site infection.
Step 7: Carefully remove the needle or the plastic catheter with one hand and with
the other hand cover the insertion site with a sterile gauze square (2x2).
Step 8: Press firmly for about a minute, or alternatively place two pieces of narrow
tape, about 1cm or 1/2-inch-wide, directly across the gauze square. Or
alternatively, after pressing on the gauze square, remove it and cover the
insertion site with a sterile band-aid.
Step 9: Prior to removing gloves, discard the needle or plastic catheter in a sharps
container and place the IV tubing and any blood-contaminated waste items
(cotton/gauze square) in a plastic bag or leak-proof covered waste container.
Step 10: Remove gloves by inverting and place them either in a plastic bag or a leak-
proof, covered waste container.
Step 11: Wash hands with soap and running water.
188
22.5. Injection Safety - Best Practices
A safe injection does not harm the client or patient, does not expose the healthcare
provider to any avoidable risk and does not result in any waste that is dangerous for
other people.
Eliminating unnecessary injections is the highest priority towards preventing injection
associated infections. When injections are medically indicated they should be
administered safely. The following best practices are measures that have been
determined through scientific evidence or expert consensus to effectively protect
patients, healthcare providers and communities.
22.5.1. Use Sterile Injection Equipment
• Use a sterile syringe and needle for each injection and to reconstitute each
unit of medication;
• Use new, quality-controlled disposable syringes and needles;
• Inspect packaging for breaches in barrier integrity, and discard a needle or
syringe if the package has been punctured, torn or damaged by exposure to
moisture;
• Use single-use syringes and needles.
22.5.2. Prevent Contamination of Injection Equipment and Medication
• Prepare each injection in a clean designated area where blood or body fluid
contamination is unlikely;
• Use single dose vials rather than multi-dose vials;
• If multi-dose vials must be used, always pierce the septum with a sterile
needle. Avoid leaving a needle in place in the stopper of the vial;
• Select pop-open ampoules rather than ampoules that require the use of a
metal file to open them;
• If using an ampoule that requires a metal file to open, protect fingers with a
clean barrier (e.g., small gauze pad) when opening the ampoule;
• Inspect medications for visible contamination or breaches of integrity (e.g.,
cracks, leaks); if any are found, discard the medication;
• Discard a needle that has touched any non-sterile surface.
22.5.3. Prevent Needle-Stick Injuries to Healthcare Providers

23.0. PREVENTING NOSOCOMIAL PNEUMONIA
Pneumonia is a complex infection that is often difficult to distinguish from other lung
diseases, especially adult respiratory distress syndrome, bronchitis, emphysema and
congestive heart failure. Most commonly accepted criteria for nosocomial pneumonia
include fever, cough, decreased breath sounds or dullness in a specific area of the
lungs and production of purulent (infected) sputum in combination with X-ray
evidence suggestive of an infection.
Nosocomial pneumonia is the infection most likely to be fatal and is the most
expensive to treat.
Most nosocomial pneumonias occur by aspiration of bacteria growing in the back of
the throat (oropharynx) or stomach. Intubation and mechanical ventilation greatly
increase the risk of infection because they:
• Block the normal body defence mechanisms – coughing, sneezing and the
gag reflex;
• Prevent the washing action of the hair (cilia) and mucus-secreting cells lining
the upper respiratory system provide a direct pathway for microorganisms to
get into the lungs;
• Other procedures that may increase the risk of infection include oxygen
therapy, intermittent positive pressure breathing (IPPB) treatment and
endotracheal suctioning.
Most nosocomial pneumonias occur after surgery, especially if mechanical ventilation
is needed postoperatively, and most reported cases of nosocomial pneumonia are
due to bacteria. The combination of severe illness, the presence of multiple invasive
devices (IVs, urinary catheters and mechanical ventilators) and frequent contact with
the hands of personnel often leads to cross-contamination.
193
24.0. PREVENTING URINARY TRACT INFECTIONS
Urinary Tract infections (UTIs) are the most common type of nosocomial infections,
accounting for 40% of all infections in hospitals per year (Burke and Zavasky, 1999).
In addition, several studies have reported that about 80% of nosocomial UTIs occur
following instrumentation, primarily catheterization (Asher, Oliver and Fry, 1986).
Because nearly 10% of all hospitalized patients are catheterized, preventing UTIs is
a major factor in decreasing nosocomial infections.
Organisms attacking any portion of the urinary system cause urinary tract infections:
the kidneys (pyelonephritis), bladder (cystitis), prostate (prostatitis), urethra urethritis)
or urine (bacteriuria). Once bacteria infect any site, all other areas are at risk.
24.1. Microbiology
Most nosocomial UTIs are caused by gram-negative coliform bacteria, particularly
Escherichia coli, pseudomonas species, and organisms from the Enterobacter group.
Collectively they account for more than 80% of culture-positive UTIs (Haley et al.,
1985).
While the most common organism is E. coli, infections with fungi, such as the
candida species, have increased with the advent of HIV/AIDS and widespread use of
broad-spectrum antibiotics.
Factors that can lead to bacteriuria and UTIs include:
• Passage of organisms from the urine bag to the bladder (retrograde
contamination) that occurs in patients with indwelling catheters (i.e., those left
in place for several days or weeks);
• Ability of some organisms to grow on the outside or inside of the tubing and
even in the urine itself.
• The first way (backward flow of urine in the catheter) is the more common
infection in men.
• The second (organisms migrating into the bladder along the outside of
the catheter) is more common in women in part because of their shorter
urethra. As a consequence, women are more likely to develop a UTI from
organisms located in the vagina (Garibaldi et al., 1980).
Placement of an indwelling catheter should be performed only when other methods
of emptying the bladder are not effective, and it is particularly important to limit the
duration as much as possible.
Other methods for management of urinary tract problems include: intermittent
catheterization using a sterile straight catheter, condom catheters for male patients,
adult diaper pads, bladder retraining and the use of drugs to stimulate urination. Loss
of control (incontinence) or inability to void (retention) may be managed better by
straight (in and out) catheterization several times daily rather than by putting in an
indwelling catheter.
195
• A sterile indwelling urinary catheter with a closed continuous drainage system,
or a high-level disinfected or sterile straight catheter and a clean urine
collection container;
• Sterile syringe filled with boiled or sterile water for blowing up the balloon of
an indwelling catheter;
• Pair of sterile gloves;
• Antiseptic solution (2% Chlorhexidene gluconate or 10% Povidone-Iodine);
• Sponge holding forceps with gauze squares (2x2) or large cotton applicators;
• Single-use packet of lubricant;
• Light source (flashlight or lamp) if needed;
• Basin of clean warm water, soap, a face cloth and paper towel;
• Plastic bag or leak-proof covered waste container for disposal of
contaminated items.
Step 2: Prior to starting the procedure:
• Have women separate their labia and gently wash the urethral area and inner
labia have men retract their foreskin and gently wash the head of the penis
and foreskin
Step 3: Wash hands with soap and clean water and dry with a clean dry paper towel.
Apply about 1 teaspoonful, of a waterless, alcohol-based antiseptic hand rub
to both hands and vigorously rub the hands and between the fingers until dry.
Step 4: Put surgical gloves on both hands.
Step 5: Use a small a catheter as consistent with good drainage.
Step 6: For health workers who are right-handed (dominant hand) stand on the
patient’s right side (and on the left side if left-handed).
Step 7: For women: separate and hold the labia apart with the non-dominant hand
and prep the urethral area two times with an antiseptic solution using either
cotton applicators or sponge forceps with gauze squares.
Step 8: For men: push the foreskin and hold the head of the penis with the non-
dominant hand; then prep the head of the penis and urethral opening two
times with an antiseptic solution, using cotton applicators or a sponge
forceps with gauze squares.
Step 9: If inserting a straight catheter, grasp the catheter about 5cm (2 inches) from
the catheter tip with the dominant hand and place the other end in the urine
collection container.
Step 10: For women, gently insert the catheter until urine flows. For children insert
only about 3cm (1.5inches).
Step 11: For men, gently insert the catheter about 18-22cm (7-9 inches) or until urine
flows. For children insert only about 5-8cm (2-3 inches).
196
Step 12: If inserting an indwelling catheter, push another 5cm (2inches) after urine
appears and connect to the urine collection tubing if not using a closed
system.
Step 13: For an indwelling catheter: inflate the balloon, pull out gently to feel
resistance and secure the indwelling catheter properly to the thigh or lower
abdomen.
Step 14: For straight (in and out) catheterization, allow the urine to slowly drain into
the collection container and then gently remove the catheter.
Step 15: Place soiled items, including the straight catheter if it is to be disposed of, in
a plastic bag or leak- proof, covered waste container.
Step 16: Alternatively, if a straight catheter is to be reused, place it in 0.5% chlorine
solution and soak it for 10 minutes for decontamination.
Step 17: Remove gloves by inverting and place them either in a plastic bag or waste
container.
Step 18: Wash hands or use an antiseptic hand rub as above.
Removal and or Replacement
Step 1: Make sure all items are available (as step 1 above if replacing an indwelling
catheter):
• Pair of examination gloves;
• Empty sterile syringe for removing the fluid from the catheter balloon;
• Sponge holding forceps with gauze square (2x2) or large cotton applicators;
• Plastic bag or leak-proof, covered waste container for disposal of
contaminated items.
Step 2: Have the patient wash the urethral area (women) or the head of the penis
(men) or do it for them wearing a pair of clean examination gloves.
Step 3: Wash hands with liquid soap and running water.
Step 4: Put clean single examination gloves on both hands.
Step 5: With the empty syringe, remove the water from the catheter balloon.
Step 6: For women, separate and hold the labia apart with the non-dominant hand,
then prepare the urethral area twice with antiseptic solution using cotton
applicators or a sponge forceps with gauze squares, and gently remove the
catheter.
Step 7: For men, push back the foreskin and hold the head of the penis with the non
dominant hand, then prepare the head of the penis and the area around the
catheter two times with an antiseptic solution, using cotton applicators or
sponge holding forceps with gauze squares and gently remove the catheter.
Step 8: If you are just removing the catheter, then follow steps 15, 17 and 18 of the
Insertion Procedure.
197
Step 9: If you are replacing the indwelling catheter, follow steps 4 through 18 of the
Insertion Procedure.
24.3.1. Tips for Preventing Infections in Catheterized Patients
198
25.0. INFECTION PREVENTION FOR HAEMODIALYSIS PATIENTS
Infections (including those affecting the bloodstream) are the second leading cause
of death among haemodialysis patients. Infections acquired in dialysis units can kill,
disable, hospitalize, and/or prolong illness in patients while disrupting lives and
increasing the cost of treatment.
Dialysis-related infections can occur in many body locations including the
bloodstream, bones, lungs, and skin. There are many reasons why patients receiving
dialysis have a high risk of infections, including the close distance of patients to each
other, the fast patient turn-over between dialysis sessions, and poor health of the
person receiving dialysis.
The immune system of patients with chronic kidney disease often does not work well,
which impairs their ability to fight infection. Some of the medicines may also affect
the immune system, which can increase the risk of getting an infection. Frequent
admissions to a hospital may also expose patients to infections such as central line-
associated bloodstream infections (CLABSI), Methicillin-Resistant Staphylococcus
Aureus (MRSA), and catheter-associated urinary tract infections (CAUTI).
• Clean fistula site with soap and water before every dialysis treatment;
• Clean hands with soap and water or waterless alcohol-based sanitizer before
you start your dialysis session and after you leave;
• If you have a catheter, wear a mask while the nurse is hooking you up to the
dialysis machine to prevent germs from your mouth from falling or spraying
onto the catheter;
• If you don’t have a permanent fistula, but will need dialysis for your lifetime,
discuss the early placement of a fistula with your doctor, before the need for
dialysis;
• Get the flu vaccine every year;
• Get the hepatitis B vaccine. If you or a loved one must visit a dialysis center to
receive hemodialysis (a method that removes waste from the blood when the
kidneys do not work properly), there are some important things you need to
know to prevent infections;
199
• Prevention and Management of HIV Infection. Routine testing of hemodialysis
patients for HIV infection for infection control purposes is not necessary or
recommended. However, patients with risk factors for HIV infection should be
tested so that, if infected, they can receive proper medical care and
counselling regarding preventing transmission of the virus. Infection control
precautions recommended for all haemodialysis patients are sufficient to
prevent HIV transmission between patients. HIV-infected patients do not have
to be isolated from other patients or dialyzed separately on dedicated
machines. In addition, they can participate in dialyzer reuse programs.
Because HIV is not transmitted efficiently through occupational exposures,
reprocessing dialyzers from HIV-positive patients should not place staff
members at increased risk for infection (CDC,2001);
• Patients infected with HTLV-III/LAV can be dialyzed by either haemodialysis or
peritoneal dialysis and do not need to be isolated from other patients. The
type of dialysis treatment (i.e., haemodialysis or peritoneal dialysis) should be
based on the needs of the patient;
• Clean your fistula site with soap and water before every dialysis treatment;
• Clean your hands with soap and water or waterless alcohol-based sanitizer
before you start your dialysis session and after you leave;
• If you have a catheter, wear a mask while the nurse is hooking you up to the
dialysis machine to prevent germs from your mouth from falling or spraying
onto the catheter;
• If you don’t have a permanent fistula, but will need dialysis for your lifetime,
discuss the early placement of a fistula with your doctor, before the need for
dialysis;
• Get the flu vaccine every year;
• Get the hepatitis B vaccine. The cornerstone of preventing HBV infection and
its sequelae is vaccination, which is recommended for all patients undergoing
chronic haemodialysis and the healthcare providers who care for them;
• In addition to Standard Precautions, isolation (separate room) for HBsAg
positive patients is standard of practice in haemodialysis facilities;
• Tetanus: a dose of dT which contain diphtheria toxoid (D) and tetanus toxoid
(T) in combination with other antigen should be given every 10 years; a single
dose of dT with acellular pertussis vaccine;
• Tetanus, Diphtheria, Pertussis (Tdap) can be substituted for those under 65
years of age. This assumes the patient has completed a primary series. If not,
this should be done;
• It is critical to ensure that screening for latent TB infection in patients with
renal failure occurs at a very early stage. CDC recommends (and CMS
requires) that all haemodialysis patients be screened for TB at baseline and
whenever exposure is suspected;
200
• If you will receive intravenous fluids, request that they do not use the bag for
other patients or set up the intravenous tubing until they are ready to
administer fluid to you;
• Notify a nurse or doctor if the area around the central line is painful or
inflamed, secreting (pus), or if the bandage becomes wet or unclean;
• Seek medical attention immediately if you develop symptoms such as fever,
uncommon fatigue, loss of appetite, nausea, vomiting, and/or changes in
mental activity. Sometimes patients on dialysis do not develop a fever when
they have an infection, so all symptoms are important;
What patients can ask:
• Ask for a hepatitis C blood test before starting dialysis treatment, and then on
a routine basis. Infection control techniques to prevent HCV transmission in
dialysis centers have been primarily centered on safe injection practices, use
of hand hygiene and adequate cleaning of environmental surfaces and
equipment between patients. Isolation of patients with HCV infection, as has
been done with patients with HBV infection, is not recommended by the CDC
or Kidney Disease Outcomes Quality Initiative (KDOQI);
• Before receiving an injection, ask if the needle and syringe have been newly
opened for you since syringes and needles must be used one time only;
• Ask doctors and nurses to explain why a central line is required, how long you
will need to have it in, and if you can use a fistula or graft for dialysis
treatment;
• Ask if the dialysis staff put a new external (transducer) filter on the dialysis
machine for every patient and replace the filter when it is soaked with blood.
This prevents blood from contaminating the inside of the dialysis machine and
prevents patient exposure to contaminants;
• Ask if the water used for dialysis is routinely tested for bacteria and if there is
a policy in case levels are higher than acceptable;
• Ask if your dialysis caregiver has received the flu vaccine this year;
What patients should observe:
• Check to see if dialysis staff have cleaned their hands before and after they
touch you or your dialysis machine;
• Make sure your nurse wears a mask during the initiation and discontinuation
of the treatment with a catheter;
• Observe if the dialysis staff cleans the skin of your fistula well with an
antiseptic before hooking you up to the dialysis machine;
• Observe if the chair, table, and machine are cleaned between each patient
use;
• What family members or other visitors can do:
201
• Wash hands or use an alcohol-based hand sanitizer before and after touching
you;
• Wear gloves and a clean cover gown to prevent contamination of clothing:
• Keep wounds covered with a bandage:
• Avoid sharing personal items and clothing;
• If you will receive intravenous fluids, request that they do not use the bag for
other patients or set up the intravenous tubing until they are ready to
administer fluid to you;
• Notify a nurse or doctor if the area around the central line is painful or
inflamed, secreting (pus), or if the bandage becomes wet or unclean;
• Seek medical attention immediately if you develop symptoms such as fever,
uncommon fatigue, loss of appetite, nausea, vomiting, and/or changes in
mental activity. Sometimes patients on dialysis do not develop a fever when
they have an infection, so all symptoms are important;
What family members or other visitors can do:
• Wash hands or use an alcohol-based hand sanitizer before and after touching
you;
• Wear gloves and a clean cover gown to prevent contamination of clothing;
• Keep wounds covered with a bandage;
• Avoid sharing personal items and clothing.
What HCWs should do:
There are certain products and principles which are recommended in order to
optimize environmental cleaning in healthcare settings, including HD facilities. These
include the following tasks which are typically performed by the dialysis nurse or
technician:
• Store cleaner/disinfectant separately from skin antiseptics/patient supplies
(separate shelves and below patient supplies to avoid potential
contamination);
• Perform hand hygiene before and after cleaning the patient station;
• Don gloves when using cleaner/disinfectants;
• Use one set of cleaning cloths or disposable germicidal wipes for each patient
station;
• Use microfiber cloths and mops if possible (more effective cleaning products
than regular cotton cleaning cloths);
• Clean all frequently touched or “high touch” surfaces in the “patient zone”
between patient treatments (chair, armrests, counters, drawer/cupboard
handles, exterior surface of the HD machine)—please note that some of these
202
high touch surfaces may be right outside the patient zone (e.g., computer
stations), and must also be cleaned between patient treatments;
• Clean the top of an object first and work down to avoid soiling surfaces just
cleaned. If using cleaning cloths instead of disposable germicidal wipes:
• When using a disinfectant cleaner, wet the surface, use friction to clean, and
allow to air dry;
• Fold the cleaning cloth in a series of squares to provide a number of potential
cleaning surfaces. A wadded cloth does not clean efficiently;
• Replace cloth as needed. More than one cloth may be required for a patient
station;
• Never use the same cleaning cloth for more than one patient unit;
• Never re-dip used cloth into clean disinfectant solution;
• Additional cleaning functions, typically performed by housekeeping staff in
haemodialysis facilities, should include at the end of the day:
– Wet mop the floor;
– Clean patient/staff bathrooms and restock paper products/hand hygiene
supplies;
– Check and refill all hand hygiene product dispensers in nursing stations
and at patient stations (soap, paper towels, lotion, alcohol-based hand
sanitizer);
– On a routine basis, walls and high dusting should be performed;
– Cleaning and disinfection of these surfaces (patient zone/high touch
surfaces) should be performed between all patient treatments, no matter;
– Key principles related to equipment cleaning/disinfection that should be
adhered to in order to reduce the risk of cross-contamination in
haemodialysis settings follow;
– Items taken into an individual haemodialysis patient station should be
disposed of after use, dedicated for use on a single patient, or cleaned
and disinfected before being taken to a common clean area or used on
another patient;
• Non-disposable items that cannot be comprehensively cleaned and
disinfected (e.g., adhesive tape, cloth covered blood pressure cuff s) should
be dedicated for use on a single patient;
• External venous and arterial pressure transducer filters/protectors should be
changed after each patient treatment, and should not be reused. Internal
transducer filters do not need to be changed routinely between patients;
• When reprocessing or disposing of dialyzers, dialyzer ports should be capped
and tubing clamped. The used dialyzer should be placed in a leak proof
container for transport from the patient station to the reprocessing area.
Gloves should be worn at a minimum. Gowns are required if there is any risk
of contamination of clothing;
203
• All equipment, including the front of the dialysis machine, should be
considered contaminated after a patient dialysis session;
• Non-disposable instruments (scissors, hemostats, clamps, etc.) which have no
contact with sterile tissue or mucous membranes may become contaminated
during the procedure. To facilitate thorough cleaning of the hinges and joints,
these instruments should be fi rst submerged and cleaned (e.g., with
enzymatic detergent, rinsed thoroughly, then soaked in an appropriate
disinfectant according manufacturer’s instructions— typically low level
disinfectant unless visibly contaminated with blood—then tuberculocidal
disinfectant);
• The alternative would be to send the instruments to the Sterile Processing
Department, if available, for reprocessing. Wiping with a cloth saturated with
disinfectant may not be adequate to thoroughly clean hinged or jointed
instruments;
• Interior Disinfection of Dialysis Machine;
• Disinfection of the internal pathways of the dialysis machine between patient
uses is not required. Dialysis machines are engineered so that the pathways
segregate blood and dialysate;
• The exception is if a blood leak event occurs. In the event of a blood leak
outside of the blood pathway, the CDC recommends internal disinfection
before the dialysis machine is used on a successive patient;
NB; consult the Haemodialysis guidelines for detail

26.0. VIRAL HAEMORRHAGIC FEVERS
Ebola and Marburg Viral Haemorrhagic Fevers (VHFs) are zoonotic diseases that
can cause a severe and life-threatening viral diseases including haemorrhagic
syndrome in humans. They have been widely reported in parts of Africa, South
America, the Middle East and Eastern Europe. Among an estimated 2.5 billion
people at risk globally, about 60% reside in Sub- Saharan Africa. The East and
Central Africa states of Sudan, Uganda and Democratic Republic of Congo, which
neighbour Tanzania, have reported cases since 1976. Given its geographical location,
level of sanitation, and high mobility of people, Tanzania will continue to have these
threats of Ebola and Marburg disease outbreaks.
26.1. Prevention and control
Good outbreak control relies on applying a package of interventions, namely case
management, surveillance and contact tracing, a good laboratory service, safe
burials and social mobilisation. Community engagement is key to successfully
controlling outbreaks. Raising awareness of risk factors for Ebola infection and
protective measures (including vaccination) that individuals can take is an effective
way to reduce human transmission. Risk reduction messaging should focus on
several factors:
Reducing the risk of wildlife-to-human transmission from contact with infected
fruit bats or monkeys/apes and the consumption of their raw meat. Animals should
be handled with gloves and other appropriate protective clothing. Animal products
(blood and meat) should be thoroughly cooked before consumption.
Reducing the risk of human-to-human transmission from direct or close contact
with people with Ebola symptoms, particularly with their bodily fluids. Gloves and
appropriate personal protective equipment should be worn when taking care of ill
patients at home. Regular hand washing is required after visiting patients in hospital,
as well as after taking care of patients at home.
Reducing the risk of possible sexual transmission, based on further analysis of
ongoing research and consideration by the WHO Advisory Group on the Ebola Virus
Disease Response, WHO recommends that male survivors of Ebola virus disease
practice safe sex and hygiene for 12 months from onset of symptoms or until their
semen tests negative twice for Ebola virus. Contact with body fluids should be
avoided and washing with soap and water is recommended. WHO does not
recommend isolation of male or female convalescent patients whose blood has been
tested negative for Ebola virus.
Outbreak containment measures, including prompt and dignified safe burial of the
dead, identifying people who may have been in contact with someone infected with
Ebola and monitoring their health for 21 days, the importance of separating the
healthy from the sick to prevent further spread, and the importance of good hygiene
and maintaining a clean environment.
205
Controlling infection in health-care settings
Health-care workers should always take standard precautions when caring for
patients, regardless of their presumed diagnosis. These include basic hand hygiene,
respiratory hygiene, use of personal protective equipment (to block splashes or other
contact with infected materials), safe injection practices and safe burial practices.
Health-care workers caring for patients with suspected or confirmed Ebola virus
should apply extra infection control measures to prevent contact with the patient’s
blood and body fluids and contaminated surfaces or materials such as clothing and
bedding. When in close contact (within 1 metre) of patients with EBV, health-care
workers should wear face protection (a face shield or a medical mask and goggles),
a clean, non-sterile long-sleeved gown, and gloves (sterile gloves for some
procedures).
Laboratory workers are also at risk. Samples taken from humans and animals for
investigation of Ebola infection should be handled by trained staff and processed in
suitably equipped laboratories.
WHO response
WHO aims to prevent Ebola outbreaks by maintaining surveillance for Ebola virus
disease and supporting at-risk countries to developed preparedness plans. The
document provides overall guidance for control of Ebola and Marburg virus
outbreaks:
Ebola and Marburg virus disease epidemics: preparedness, alert, control, and
evaluation
When an outbreak is detected WHO responds by supporting surveillance,
community engagement, case management, laboratory services, contact tracing,
infection control, logistical support and training and assistance with safe burial
practices.
WHO has developed detailed advice on Ebola infection prevention and control:
Infection prevention and control guidance for care of patients with suspected or
confirmed Filovirus haemorrhagic fever in health-care settings, with focus on Ebola
206
• Identify a VHF Coordinator to oversee and coordinate activities associated
with VHF Isolation Precautions;
• Use appropriate hand hygiene techniques including hand washing, hand
antisepsis and antiseptic hand rub;
• Wear Personal Protective Equipment (PPE) including gloves, masks, goggles,
caps, gowns, boots and aprons;
• Appropriately handle sharps, patient care and resuscitation equipment, linen,
and appropriately manage patient placement and patient environmental
cleaning;
• Safely dispose of infectious waste materials to protect those who handle them
and prevent injury or spread to the community;
• Process instruments by cleaning and then either sterilization or high-level
disinfection (HLD) using recommended procedures.
207
• A changing room for other health facility staff to use near their work area;
• A family entrance, if necessary;
• Restrict patient access to health facility staff trained to use VHF Isolation
Precautions;
• Establish a barrier between the VHF patient and uninfected patients, other
health facility staff, and visitors;
• A security barrier around the entire isolation area;
• Counsel family members about patient care;
Make sure the selected site has:
• An isolated toilet: If a toilet is not next to the patient's room, select and isolate
a toilet near the isolation area. Use it to receive the patient’s disinfected waste
and other liquid waste;
• If a toilet is not available, prepare a latrine for disposal of the patient’s and
other liquid waste;
• Adequate ventilation: The isolation room should have adequate ventilation
because chlorine disinfectants will be used. To prevent airborne or droplet
transmission of infectious agents, avoid rooms with air conditioning;
• Screened windows: If windows are left open for cooling, screen them to
prevent transmission of mosquito- and other insect-borne diseases.
Wear Protective Clothing: the protective clothing that should be worn when VHF is
present in the health facility and select appropriate items when recommended
clothing is not available.
All who attend VHF cases as described below should wear Protective Clothing:
• All doctors, nurses, and health care workers who provide direct patient care to
suspected VHF patients;
• All support staff who clean the isolation room, handle contaminated supplies
and equipment, launder reusable supplies, and collect and dispose of
infectious waste from VHF patients;
• All laboratory staff who handle patient specimens and body fluids from
suspected VHF cases;
• Laboratory support staff who clean and disinfect laboratory equipment used to
test VHF specimens;
• Burial teams who remove bodies of deceased VHF patients and prepare them
for burial;
• Family members who care for VHF patients.
208
When a VHF case is suspected in the health facility, the following protective
clothing should be worn in the isolation area:
• A scrub suit or inner layer of clothing (old shirt and trousers brought from
home);
• A pair of thin gloves;
• Rubber boots or overshoes;
• A gown or outer layer of clothing (surgical or disposable gown with long
sleeves and cuffs);
• A plastic apron worn over both layers of clothes;
• A second pair of thin or thick gloves. Wearing a second pair of gloves provides
an added measure of safety during patient care and when handling
contaminated supplies;
• A HEPA-filter (high-efficiency particulate air respirator) or other biosafety mask
(or surgical mask if HEPA-filter or other biosafety mask is not available);
• Head covering;
• Clear eyeglasses or non-fogging goggles.
209
• Put on one glove at a time. If the scrub suit or set of old clothes has long
sleeves, place the edge of each glove under the cuff;
• When only one pair of gloves is worn, place the edge of the glove over the
cuff or gown.
Put on the outer gown.
• Pick up the gown from the inside. Place arms through the armholes. Tie the
gown in back. Or, ask another health care worker to tie the gown.
Put on the plastic or rubber apron.
Put on the second pair of gloves:
• Place the edge of the second pair of gloves over the cuff of the gown;
• If using plastic bags, place the second layer of plastic bags over the first.
Close ends of the bags with plastic tape or elastic bands;
• Health facility staff who do cleaning, laundering, disinfecting, waste disposal
or handling the body should wear thick/utility gloves as the second pair of
gloves.
Put on the mask.
• Tie it at the back of the neck and towards the top of the head.
Put on a head cover.
Put on the protective eyewear.
• Attach the eyeglasses or goggles behind the head with string or cord to
prevent the eyewear from falling off when working with patients in the isolation
ward.
Remember! Make sure the mask, head cover and eyewear fit comfortably. Once
gloved hands have touched a patient, do not touch the mask, head cover and
eyewear
26.6. How to Put Off (Doffing) the PPE
The steps for removing protective clothing include disinfection with bleach solutions
and washing hands with soap and water. Outer gloves and boots are likely to have
the most contact with infectious body fluids during patient care or while conducting
other duties in the isolation unit.
Before leaving the patient’s room:
• Disinfect the outer pair of gloves;
– Wash the gloved hands in soap and water;
– Dip the gloved hands in 0.5% bleach solution for 1 minute.
• Disinfect the apron;
– Spray or wipe it with 0.5% bleach solution.
210
• Disinfect the boots.
– Use a sprayer containing 0.5% bleach/chlorine solution to spray boots OR
– Hold the foot over a pan or basin and ask another health worker to pour
0.5% bleach solution over the boots OR
– Step into a shallow pan containing 0.5% bleach solution and wipe boots
on a bleach-drenched cloth.
**Note: The soles of rubber boots are difficult to clean because they are
textured. Disinfect them carefully and make sure to reach all surfaces of the
textured soles.
After leaving the patient’s room:
• Remove the outer pair of gloves.
– If two pairs of gloves are worn:
– Pull the edge of the glove back over the gloved hand so that the glove
turns inside out as it is being pulled back.
• Remove the apron and outer gown.
– Put the apron in a laundry container or hang it for reuse (if it will be
reused).
– Remove the outer gown. Hang it on a hook for reuse. Make sure it is hung
inside out.
– If the gown needs laundering, place it in the laundry container.
• Disinfect the gloved hands
– After contact with apron and outer gown:
– Rinse the gloved hands in 0.5% bleach solution. Then wash them in soap
and water;
– Dry the gloved hands with a one-use towel.
• Remove the eyewear, head cover and mask.
– If eyewear is heavily soiled, wash the eyeglasses in soapy water and wipe
them clean. Store them in a drawer or shelf with the clean supply of
eyeglasses;
– Remove the head cover and, if unsoiled, store it with the cleaned eyewear.
If it is soiled, discard it in the bucket for disposal of contaminated waste;
– Remove the mask and hang it on a hook or store it for reuse;
– A HEPA-filter or other biosafety mask can be reused by the same health
care worker as long as it is not soiled.
• Remove the boots.
– Place a towel that has been soaked in 0.5% bleach solution on the floor
for health facility staff to stand on when removing boots;
– Use a boot remover to take off the rubber boots. Avoid touching the boots
with bare or gloved hands;
211
– Store boots safely until next use. For example, store them in a plastic
sack or on a covered shelf.
• Remove the inner pair of gloves.
– Remove the first glove with the other gloved hand. Pull the edge of the
first glove back over the gloved hand so that the glove turns inside out as
it is being pulled back;
– Place the inside-out glove in the palm of the gloved hand;
– Reach inside the glove to a clean area. Pull the glove back over the hand
so that only the inside of the glove is exposed and covers the glove held
in the palm;
– Discard the gloves in a bucket for disposal of contaminated waste;
– Wash un gloved hands with soap and water.
• Remove inner layer of clothes and dress in street clothes.
– If the inner layer is not soiled, store the clothing for reuse;
– If soiled, place the clothing in the laundry container;
– If personal shower facilities are available, shower before dressing in street
clothes;
– If skin has contact with soiled material, follow guidelines for accidental
exposure;
– Put on street clothes;
– Wash hands with soap and clean water before leaving the changing room.
212
The standard ambulance escort
• If the ambulance escort is part of the RRT:
– A driver;
– A nurse;
– 2 bearers.
• If the ambulance escort is NOT part of the RRT:
– Same as above plus an infection prevention and control expert
Transport in ambulance of an EVD suspected case in 8 steps
• Mobilisation of the RRT and ambulance escort once an EVD suspected case
alert is received
• Preparing vehicles and equipment before dispatch
• Arrival at the EVD suspected case alert location
• Removal of the EVD suspected case
• Disinfection and doffing of the PPE ambulance team (except the nurse
accompanying the patient)
• Departure of the ambulance
• Arrival of the ambulance at the Ebola Treatment Center
• Waste management and disinfection of the ambulance.
Disinfect Reusable Supplies and Equipment at the VHF isolation
VHF Isolation Precautions during patient care and when disinfecting and cleaning
contaminated surfaces, supplies and equipment. What to Disinfect: Disinfection kills
almost all bacteria, fungi, viruses, and protozoa. It reduces the number of
microorganisms to make equipment and surfaces safer for use. When VHF is
suspected in the health facility, all medical, nursing, laboratory and cleaning staff
should disinfect:
• Hands and skin after contact with a VHF patient or infectious body fluids;
• Gloved hands after contact with each VHF patient or after contact with
infectious body fluids (when gloves cannot be changed);
• Thermometers, stethoscopes and other medical instruments after use with
each VHF patient;
• Spills of infectious body fluids on the walls and floors;
• Patient excreta and containers contaminated by patient excreta;
• Reusable supplies such as protective clothing and patient bedding;
• Used needles and syringes.
213
Prepare Bleach Solutions
In a central place in the health facility, prepare solutions:
• 2% bleach solution is a strong solution used to disinfect excreta and bodies;
• It is also used to prepare the 0.5% for decontamination of table tops,
mattresses and
• 0.05% bleach solution hand washing and birthing. 0.05% bleach solution is
also used to disinfect:
– Surfaces;
– Medical equipment;
– Patient bedding;
– Reusable protective clothing before it is laundered.
It is also recommended for:
• Rinsing gloves between contacts with each patient;
• Rinsing gloves, apron, and boots before leaving the patient’s room;
• Disinfecting contaminated waste for disposal.
Bleach solutions must be prepared daily. They lose their strength after 24 hours.
Anytime the odour of chlorine is not present, discard the solution.
**Note: 0.5% bleach solution is caustic. Avoid direct contact with skin and eyes.
Prepare the bleach solutions in a well-ventilated area.
Disinfect Reusable Medical Instruments
In the isolation room, each time health care workers wash their hands between
patients, they should also disinfect thermometers and stethoscopes they have used
to examine the patient.
To disinfect thermometers and stethoscopes with alcohol:
214
To disinfect thermometers and stethoscopes with bleach solution:
• Place a covered container of 0.5% bleach solution in the isolation room.
Change the bleach solution each day;
• Use a clean cloth or paper towel and dip it in the bleach solution. Never dip a
soiled cloth back into the bleach solution. Use a cup or dipper to pour the
bleach solution on a soiled cloth;
• Wipe the thermometer with the cloth soaked in bleach solution. Or, soak the
thermometer for 10 minutes in the bleach solution. Let the thermometer air-
dry;
• Use a clean cloth or new paper towel and dip it in the bleach solution;
• Wipe the metal part of the stethoscope with 0.5% bleach solution. Let it air-
dry;
• Discard the cloth in the laundry container. Discard paper towels in the bucket
for waste to be burned.
Disinfect Bedpan or Waste Bucket:
• Cover the contents with 2% bleach. Empty the bedpan contents directly into
the isolated toilet or latrine;
• Clean the bedpan with soap and water to remove solid waste. Pour into toilet
or latrine. Rinse the bedpan in 0.5% bleach solution and return it to patient's
room.
• If a family member is responsible for carrying out this task, make sure the
family member wears protective clothing.
Disinfect Patient’s Utensils:
If families will assist with patient care, provide 0.05% bleach solution and soap and
water so the family member can wash the patient’s eating utensils. After washing the
utensils, rinse them in 0.05% bleach solution, and let them air-dry.
Disinfect Reusable Supplies and Equipment
Disinfect Spills of Infectious Body Fluids
Place a bucket containing 0.5% bleach solution in the isolation area.
To disinfect spills of infectious body fluids:
• Use absorbent materials to cover the spill;
• Collect the spill and then cover the area completely with 0.5% bleach solution
for 10 minutes. Take care to prevent drops or splashes of the contaminated
body fluid from reaching anyone when pouring bleach solution on the spill;
• Pour 2% of chlorine at the heavy spill;
• Remove the disinfected blood or spilled material with a cloth soaked with
0.05% bleach solution;
215
• Discard any waste in the container for collecting disposable infectious waste
or in the isolated latrine or toilet;
• Wash area as usual with soap and clean water.
To clean the walls or other surfaces:
Surfaces such as table tops, sinks, walls and floors are not generally involved in
disease transmission. However, in a VHF patient’s room, if walls are visibly soiled
with blood or other body fluids, clean them as follows:
• Use a sprayer or mop to wash the walls with 0. 5% bleach solution.
• Rinse the mop in a fresh supply of 0.5% bleach solution. (If using a sprayer,
apply the spray close to the surface to minimize splashing and aerosols.)
• Wash the wall as usual with soap and clean water to remove visible soil.
• Discard any waste in container for collecting infectious waste or in the isolated
latrine or toilet.
Disinfect Infectious Waste and Non-Reusable Supplies for Burning
Place a bucket or other container containing 0.5% bleach solution in the patient’s
room. Use it to collect infectious waste, contaminated items, and non-reusable
supplies that will be burned.
Clean and Disinfect Protective Clothing
Set aside a special part of the laundry or cleaning area for laundry from suspected
VHF patients. Make sure health facility staff who handle contaminated laundry wear
protective clothing, including thick gloves as the second pair of gloves:
• Transfer laundry as soon as possible to area set aside for VHF laundry;
• Carefully move the laundry to a bucket with fresh 0.05% bleach solution;
• Soak laundry in 0.05% bleach solution for 20 minutes. Be sure that all items
are completely soaked;
• Remove items from the bleach solution and place in soapy water;
• Soak overnight in soapy water;
• Scrub thoroughly to remove stains. Rinse and line-dry;
• Use a needle and thread to repair any holes or torn areas;
• The clean clothing is now ready for use. It can be ironed although this is not
necessary. (It is not necessary to wear protective clothing when ironing
cleaned clothing);
• Items that are very worn out should be discarded or used as cleaning rags.
Clean and Disinfect Boots
Place a sprayer or pan with 0.5% bleach solution at the exit of the patient's room.
Change the pan often. Steps for disinfecting boots
216
Clean and Disinfect Patient’s Bedding
For plastic sheeting:
• If the plastic sheeting becomes soiled during its use with the same patient,
remove liquid or solid waste with absorbent towels;
• Discard them in the container for collecting infectious waste for burning. Then,
wash the plastic sheeting with 0.5% bleach solution;
• Change the plastic sheeting between patients;
• If the plastic sheeting cannot be changed between patients, wash it with 1%
bleach solution after each patient.
For patient’s sheets:
• Remove sheets from bed. Put them in a container (plastic bag or bucket) in
the patient’s room;
• Take the container directly to the laundry area;
• Soak in 0.05% bleach solution for 20 minutes. Be sure all items are
completely soaked.
• Remove items from the bleach solution and place them in soapy water;
• Soak overnight;
• Scrub thoroughly to remove stains. Rinse and line-dry.
Mattresses
If a mattress is heavily soiled, remove it from the isolation area to the outdoors and
burn it. Make sure health facility staff wear protective clothing and gloves when
touching and carrying the soiled mattress.
If mattresses must be reused:
• Pour 0.5% bleach solution directly on the mattress. Let the solution soak
through completely to the other side;
• Flood the soiled area with soapy water and rinse with clean water;
• Let the mattress dry in the sun for several days;
• Turn the mattress often so it dries on both sides.
Mobilize the Community and Conduct Community Education
Provide guidance for involving the community in disease prevention and control
activities when VHF is suspected. It also describes how to choose a VHF
Coordinator.
When VHF is suspected:
• Make sure that the community knows about the VHF outbreak and how it is
transmitted;
217
• Involve the community in identifying the source of the epidemic and controlling
it;
• Reduce fear and rumours in the population;
• To develop community education in an urgent situation;
• Describe the extent of the current health problem;
• Identify and mobilize key community members who will plan and lead the
education efforts;
• Describe the target population and develop health messages;
• Plan and conduct activities to communicate messages;
• Conduct ongoing evaluation of the activities and make improvements as
needed.
Make Advanced Preparations to Use VHF Isolation Precautions
Use VHF Isolation Precautions. Advance preparations when a VHF is suspected, the
supplies. When advance preparations are not possible, VHF Isolation, Precautions
must be implemented in an emergency situation.
When a VHF case is suspected, VHF Isolation Precautions must begin immediately.
All efforts must be focused on meeting patients’ needs. There is no time to give initial
training in VHF Isolation Precautions.
Being prepared for an emergency can ultimately save lives. Health care workers will
know how to use VHF Isolation Precautions, and adequate supplies will already be
available. Disease prevention in the health facility setting will be more effective.
This section describes how to prepare for VHF Isolation Precautions.
Identify a VHF Coordinator to Oversee Preparations
Someone in the health facility may already serve as a coordinator for emergency
situations. This person can also serve as the VHF Coordinator. If the emergency
coordinator cannot assume the VHF activities, select a staff person with authority
who can serve as the VHF Coordinator. If the emergency coordinator cannot assume
the VHF activities, select a staff person with authority who can serve as VHF
Coordinator. The tasks of the coordinator:
• Oversee all the preparations for VHF Isolation Precautions;
• Serve as the focal point for information and leadership when a VHF case is
suspected;
• Inform all health facility staff about VHFs and the risks associated with them;
• Organize training in VHF Isolation Precautions for medical, nursing, and
laboratory staff who will work directly with VHF patients or infectious body
fluids;
218
• Assign responsibility to medical, laboratory, and cleaning staff for ensuring
that all the necessary precautions, treatment protocols and clean up
procedures are carried out within their areas;
• Hire or reassign and train additional cleaning staff for work with disinfection of
waste, clothing, and equipment;
• Make sure that teams are trained to prepare and transport bodies for burial;
• Routine handwashing practices should be part of the minimum level of
Standard Precautions used with all patients in the health facility;
• To reinforce consistent handwashing practices, regularly monitor the practices
and improve them as needed. For example:
– Has handwashing been identified as a routine practice in the health
facility?
– Do all staff wash their hands after contact with each patient, especially
new patients with fever?
– Are there reliable supplies of liquid soap and running water or buckets
with clean water available in areas where health workers should use
them?
– Are posters reminding health workers to wash their hands placed in areas
where health workers can see them?
When a VHF case is suspected, the health facility will immediately take steps to limit
its transmission. These include steps to:
• Create an isolation room for VHF patients;
• Limit contact with VHF patients to a small number of specially trained staff and,
in some areas, a family member who has received information and training in
VHF Isolation Precautions;
• Limit the use of invasive procedures as much as possible in treatment of VHF
patients;
• Use protective clothing for all staff who have contact with VHF patients or their
body fluids;
• Use safe disinfection and waste-disposal methods.
220
• Immerse the exposed site in 70% alcohol for 20 to 30 seconds, and wash with
soap and clean water;
• Flush the site in running water for 20 to 30 seconds;
• If needed, cover with a dressing;
• Report the incident to a supervisor or the physician-in-charge;
• The purpose of notifying the physician-in-charge is:
– To identify what caused the problem
– To take corrective action to solve the problem and prevent accidental
transmission
– To provide appropriate care for the possible case of VHF.
Remind the health facility staff that accidents do happen even when every precaution
to prevent them has been taken. Reassure health facility staff that reporting the
accidental exposure will have no negative consequences. Explain that reporting the
accidental exposure is essential for protecting themselves, their families, other health
workers and patients.
Accidental contact with infectious body fluids: An accidental contact can occur if
there is unprotected contact between infectious body fluids and broken skin or the
mouth, nose or eye.
For example, vomit may run under a glove, a patient might cough blood which runs
into the health care worker's eye, or coughed blood may run underneath a health
care worker's mask and get into the mouth. Treat any accidental contact as a
suspected contact with VHF. As soon as the contact occurs:
• Flush the area in the most appropriate manner with soap and clean water. If a
splash occurs in the eye, flush it with clean water;
• Leave the isolation area and remove the protective clothing as recommended;
• Take a shower and put on street clothes;
• Report the exposure to a supervisor or the physician-in-charge. Complete the
necessary forms.
Follow up accidental exposures:
• Monitor the condition of the health facility staff. Take a measured temperature
two times per day;
• If a fever occurs -- temperature is 38.5oC (101oF) or higher –the health facility
staff should not do patient care activities.
Treat as a suspected case of VHF if the health facility staff’s signs and symptoms
meet the case definition.
221
Isolation of the Patient
Isolating the VHF patient will:
• Restrict patient access to health facility staff trained to use VHF Isolation
Precautions;
• Establish a barrier between the VHF patient and uninfected patients, other
health facility staff, and visitors.
Select Site for the Isolation Area
Ideally, an isolation area should already be available to admit patients requiring
isolation. If an isolation area is not available or if advance preparations have not
been done, and VHF is suspected, immediately identify and set aside:
• A room with an adjoining toilet or latrine;
• A separate building or ward that can be used with VHF patients only
(especially if Ebola haemorrhagic fever is suspected, or if there is a large
number of patients);
• An area in a larger ward that is separate and far away from other patients in
the ward;
• An uncrowded corner of a large room or hall;
• Any area that can be separated from the rest of the health facility (TB rooms,
isolation ward for infectious diseases, private or semiprivate rooms).
Make sure the selected site has:
• An isolated toilet: If a toilet is not next to the patient's room, select and isolate
a toilet near the isolation area. Use it to receive the patient’s disinfected waste
and other liquid waste.
• If a toilet is not available, prepare a latrine for disposal of the patient’s and
other liquid waste.
• Adequate ventilation: The isolation room should have adequate ventilation
because chlorine disinfectants will be used. To prevent airborne or droplet
transmission of infectious agents, avoid rooms with air conditioning.
• Screened windows: If windows are left open for cooling, screen them to
prevent transmission of mosquito- and other insect-borne diseases.
• Restrict access. Tie a rope or line around the area outside the window to
restrict the area and prevent entry through the window.
• Make use of the available space and design of the health facility to arrange
the isolation area. The diagram below shows an example of arrangement for
an isolation area
222
Dispose of Waste Safely: step-by-step procedures for disposal of VHF-
contaminated waste and detailed instructions for building an incinerator from
available material. Direct, unprotected contact during disposal of infectious waste
can result in accidental transmission of VHF. For this reason, all contaminated waste
produced in the care of the VHF patient must be disposed of safely. All non-reusable
items should be destroyed in the isolation area so they cannot be used again.
Burning should be carried out at least daily.
What Needs Disposal
When VHF is suspected, disinfect and dispose of:
• Infectious blood and other body fluids such as urine, faeces, and vomitus;
• Disposable needles and syringes and disposable or non-reusable protective
clothing;
• Treatment materials and dressings;
223
• Non-reusable gloves;
• Laboratory supplies and biological samples;
• Used disinfectants.
Recommended Disposal Methods: Liquid waste, including patient excreta, can be
disposed of in an isolated latrine or toilet set aside for VHF cases. Burning is the
recommended method for disposal of other VHF-contaminated waste. A safe and
inexpensive disposal system can be made by using an incinerator or a pit for burning.
• A latrine or toilet that joins the patient's isolation room can be used to receive
the disinfected bedpan contents from the VHF patient. The latrine or toilet
should be isolated. Access should be restricted to health facility staff trained to
work in the VHF isolation area.
• Incinerators are containers with holes for ventilation to allow air to enter and
exit the container. This allows the fire to reach temperatures high enough to
completely destroy all biological materials. Use flammable fuel (such as diesel
fuel) to speed the burning process and keep the temperatures high.
• Incineration is recommended for disposal of:
– Needles and syringes;
– Used treatment materials and dressings;
– Non-reusable protective clothing;
– Laboratory supplies.
• When an incinerator is not available, burn waste in a pit.
• Use fuel to accelerate the burning and ensure that all waste is completely
destroyed.
• Use a pit to dispose of:
– Disinfected body fluids such as urine, faeces, and vomitus when no
designated latrine or toilet is available. Used disinfectants. If it is not
possible to dispose of used disinfectants in a latrine or toilet, burn the
used disinfectant together with flammable items (disposable gowns or
masks, for example). Burning with the flammable items will help keep the
temperature of the fire hot enough to boil off the liquids.
**Note: All staff who are likely to handle infectious material should know and use
VHF Isolation Precautions. Reinforce with all health facility staff the importance of
handling infectious waste safely.
Select a person with authority who will:
• Oversee all the disposal procedures, including preparation of the incinerator
and pit;
• Train and supervise the staff who carry out waste disposal;
• Make a schedule for collecting and burning disposable waste;
• Supervise the collection and burning to make sure it is carried out safely.
224
26.9. Use dignified Safe Burial Practices: how to prepare bodies of deceased
VHF patients safely for burial and how to prevent disease transmission through
contact with the deceased patient. There is risk of transmission in the health facility
when a VHF patient dies because the bodies and body fluids of deceased VHF
patients remain contagious for several days after death. Family and community
members are also at risk if burial practices involve touching and washing the body.
Prepare the Body Safely
Burial should take place as soon as possible after the body is prepared in the health
facility. Health facility staff should:
• Be aware of the family’s cultural practices and religious beliefs. Help the
family understand why some practices cannot be done because they place
the family or others at risk for exposure;
• Counsel the family about why special steps need to be taken to protect the
family and community from illness. If the body is prepared without giving
information and support to the family and the community, they may not want to
bring other family members to the health facility in the future. They may think
that if the patient dies, the body will not be returned to them;
• Identify a family member who has influence with the rest of the family and who
can make sure family members avoid dangerous practices such as washing
or touching the body.
To prepare the body in the health facility:
• Wear protective clothing as recommended for staff in the patient isolation area.
Use thick rubber gloves as the second pair (or outer layer) of gloves;
• Spray the body and the area around it with 0.5% bleach solution;
• Place the body in a “body bag” (mortuary sack) and close it securely. Spray
the body bag with 0.5% bleach solution;
• If body bags are not available, wrap the body in two thickness of cotton cloth
and soak with 0.5% bleach solution. Then wrap the body in plastic sheeting.
Seal the wrapping with plastic tape. Spray the body bag as in:
– Place the body in a coffin if one is available;
– Transport the body to the burial site as soon as possible;
– Assign a health officer or health facility staff person to accompany the
body to ensure that the safety precautions remain secure during the
journey.
Transport the Body Safely
VHF Isolation Precautions should remain in force when the body is being transported
to the burial site:
225
• Plan to take the shortest route possible for security purposes and to limit any
possibility of disease transmission through accidental contact;
• Any health facility staff who must touch or carry the body during transport
should wear the same protective clothing as is worn in the isolation area.
Note: The driver does not need to wear protective clothing if there is no
contact with the body;
• Take a closed container or sprayer with 1:10 bleach solution in the event of
any accidental contact with the body or infectious body fluids. Also use it to
clean up spills in the transport vehicle.
Prepare Burial Site
• The staff person who disinfects the vehicle must wear protective clothing;
• Rinse the interior of the vehicle where the body was carried with 0.5% bleach
solution.
• Let it soak for 10 minutes;
• Rinse well with clean water and let the vehicle air-dry. Be sure to rinse well
because the solution is corrosive to the vehicle.
226
27.0. PREVENTING NOSOCOMIAL DIARRHEA
Controlling the spread of nosocomial diarrhoea from contaminated food is an
ongoing concern in hospitals and nursing homes. Frequently this is due to poorly
trained food- handling staff using unsafe practices involving the storage, preparation
and handling of raw meat, chicken, fish, fresh eggs and vegetables.
27.1. Definitions
228
28.0. OUTBREAK MANAGEMENT FOR DIARRHOE CONDITIONS:
PREVENTION AND CONTROL OF CHOLERA OUTBREAKS
28.1. Diagnosis
The presence of V. cholerae in stools is confirmed through laboratory procedures.
However, a new rapid diagnostic test (RDT), now available, allows quick testing at
the patient's bedside. WHO is currently in the process of validating this RDT, to be
able to include it on the list of its pre-qualified products.
In the meantime, WHO suggests that all samples tested positive with the RDT are re-
tested using classic laboratory procedures for confirmation. Not all cases fitting the
WHO clinical case definition need to be tested. Once an outbreak is confirmed, a
clinical diagnosis using WHO standard case definition is sufficient1, accompanied by
sporadic testing at regular intervals.
28.2. Prevention
Measures for the prevention of cholera mostly consist of providing clean water and
proper sanitation to populations who do not yet have access to basic services.
Health education and good food hygiene are equally important. Communities should
be reminded of basic hygienic behaviours, including the necessity of systematic
hand-washing with soap after defecation and before handling food or eating, as well
as safe preparation and conservation of food. Appropriate media, such as radio,
television or newspapers should be involved in disseminating health education
messages. Community and religious leaders should also be associated to social
mobilization campaigns.
In addition, strengthening surveillance and early warning greatly helps in detecting
the first cases and put in place control measures. Conversely, routine treatment of a
community with antibiotics, or mass chemoprophylaxis, has no effect on the spread
of cholera, can have adverse effects by increasing antimicrobial resistance and
provides a false sense of security.
28.3. Control
Among people developing symptoms, 80% of episodes are of mild or moderate
severity. The remaining 10%-20% of cases develop severe watery diarrhoea with
signs of dehydration. Once an outbreak is detected, the usual intervention strategy
aims to reduce mortality - ideally below 1% - by ensuring access to treatment and
controlling the spread of disease. To achieve this, all partners involved should be
properly coordinated and those in charge of water and sanitation must be included in
the response strategy. Recommended control methods, including standardized case
management, have proven effective in reducing the case-fatality rate.
The main tools for cholera control are:
• Proper and timely case management in cholera treatment centres;
229
• Specific training for proper case management, including avoidance of
nosocomial infections;
• Sufficient pre-positioned medical supplies for case management (e.g.
diarrhoeal disease kits);
• Improved access to water, effective sanitation, proper waste management and
vector control;
• Enhanced hygiene and food safety practices;
• Improved communication and public information.
230
Careful and regular laboratory monitoring of the antibiotic sensitivity of circulating
strains is recommended in all settings, including during an outbreak, to guide
treatment. O1 and O139 Vibrio cholerae strains that are resistant to antibiotics such
as cyclines and quinolones have been isolated from all regions.
231
28.7. Cholera vaccines
There are two WHO prequalified oral cholera vaccines (OCV) currently available on
the market. These vaccines were proven safe, effective and well accepted and are
available for individuals aged one year and above. They are administered in two
doses given at least 7 days apart. Overall, more than 1.6 million doses of WHO
prequalified OCVs have been deployed in mass vaccination campaigns since 1997.
WHO official recommendations for the use of OCV have been issued, and state that:
• The OCV should always be used as an additional public health tool and
should not replace usually recommended control measures such as improved
water supplies, adequate sanitation and health education. It needs also to be
linked to strengthened surveillance and early warning;
• Pre-emptive vaccination campaigns with OCV should be used in areas where
the disease is endemic, including during humanitarian crises, as an additional
means for cholera prevention and control, but should not replace usually
recommended control measures such as improved water supply, adequate
sanitation, food safety, and health education. In such settings, vaccination
should be targeted at high-risk areas and high risk population groups, such as
displaced populations in camps with precarious living conditions, underserved
populations in resource poor settings, etc.;
• Mass vaccination campaigns may be organized on a reactive basis, as part of
the response to a cholera outbreak which has already commenced, to reduce
mortality and limit the spread of the disease. However, vaccination should not
disrupt the provision of other high-priority health interventions to control or
prevent cholera. Considering the lack of experience with implementing
reactive vaccination against cholera, the feasibility and impact of vaccination
in halting on-going outbreaks should be documented and results widely
disseminated.
The use of the parenteral cholera vaccine has never been recommended by WHO
due to its low protective efficacy and the high occurrence of severe adverse
reactions
232
• Routine treatment of a community with antibiotics, or mass chemoprophylaxis,
has no effect on the spread of cholera, can have adverse effects by increasing
antimicrobial resistance and provides a false sense of security;
• Restrictions in travel and trade between countries or between different regions
of a country;
• Set up a cordon sanitaire at borders, a measure that diverts resources,
hampers good cooperation spirit between institutions and countries instead of
uniting efforts.
Healthcare providers should take precautions to prevent the spread of cholera in
clinical settings:
• Chemoprophylaxis with antibiotics is not indicated for healthcare providers;
• Hand washing with soap and clean water should be done before and after
each patient contact;
• If no water and soap are available, use an alcohol-based hand cleaner (with at
least 70% alcohol);
• Several chlorine solutions can be used for disinfection (solution calculations
are based on using unscented household bleach with 5–6 % active chlorine):
– 2% Chlorine: made by mixing 3 parts water and 2 parts bleach used for
disinfecting vomit, faeces, and corpses
– 0.5% Chlorine: made by mixing 9 parts water and 1 part bleach used for
foot baths, cleaning floors, bedding, latrines
– 0.05% Chlorine: made by mixing 9 parts water and 1 part 0.5% chlorine
solution used for bathing soiled patients, handwashing, rinsing dishes,
laundry
233
• Availability of sanitary facilities (temporary);
• Provision for extension of CTC (basing on estimation given by epidemiologist).
Setting up a camp
Site management
There are different recommendations for different situations/circumstances:
In urban settings and refugee camps:
• CTC + several Oral Rehydration Points (ORPs)
Ideally the CTC should be located inside the existing hospital premises but
clearly separated and isolated from the other departments to avoid spread of
infection to non-cholera patients. If the hospital premises are not suitable,
another site must be found. In urban/camp settings, It is preferable to have
one single CTC and several ORPs rather than setting up multiple CTCs,
thereby increasing potential sources of infection. When affected areas are too
far from the CTC, access can become a problem. Ambulances can be
provided for referral, or a CTU may be established as an intermediate
structure. Use of taxis/buses should be discouraged given the high
contamination risk during the journey.
In rural settings:
• Establish Cholera Treatment Units (CTU)
The CTU should be located inside the health facility, or close to it. If this is not
possible, other existing structures may be used. CTUs may paralyses routine
health services as adequate case management is labor-intensive and other
health services may suffer from staff shortage. In areas that are far from any
treatment facility, it may be possible to decentralize the CTU to the level of the
affected villages.
• Oral rehydration Points (ORPs)
ORS points have two objectives: to treat patients, and to screen off and refer
severely dehydrated patients to CTC/CTU(s). They reduce pressure on
overburdened CTCs or CTUs. They can be decentralized to the community
level. The community health worker should receive quick training and regular
supplies, to be able to achieve given objectives.
Setting up a temporary cholera treatment camp
• In setting up a cholera camp, you can use an existing building or set up tents;
• It is important to consider safety of patients and ventilation as high
temperatures contribute to dehydration of the patients;
• The cholera camp should operate 24 hours a day independently of the other
health facilities and therefore the necessary staff has to be recruited;
234
• It should be supplied with the necessary medical material specifically for the
centre;
• An enclosure or other form of acceptable screen should be provided around
the cholera camp;
• The various workstations should be clearly labelled and directions provided;
• The CTC must be a “closed system” where contamination is introduced
through patients and must be destroyed inside the structure. Under no
circumstances should any contamination come out (through patients, water,
material, solid and liquid waste etc.).
General rules for a good design:
• Strict necessary movement for staff and patient;
• Each zone is a “closed box”;
Systematic disinfection between zones:
• Discipline and mutual control for the patient, attendant and staff on hygiene;
NOTE: Other details are in National Guidelines for Prevention and Control of
Cholera
235
29.0. HEALTH LABORATORY
Health laboratory personnel, especially the staff of microbiology, work with infectious
organisms and materials that do or may contain microorganisms. Some of these
organisms are pathogenic and potentially dangerous.
Avoidance of infection is thus an essential element of the professional expertise of
the workers. It is necessary to protect not only themselves but also to protect their
materials from possible cross-contamination that may invalidate their work by giving
false results. Health laboratory workers are also at risk of chemical, fire and radiation
hazards.
The World Health Organization has given guidance regarding hazards of infective
microorganisms by risk group, and thus laboratories are designated by level
according to their design features, construction and containment facilities (safety
precautions and equipment) as Basic Biosafety Level 1, Basic Biosafety Level 2,
Containment – Biosafety Level 3 and Maximum Containment – Biosafety Level 4.
Depending on the laboratory level, the health worker is referred to the WHO safety
guidelines (Biosafety Level (BSL) guidelines).
29.1. Definitions
Biological safety cabinets (BSCs) are devices that provide protection for personnel,
the agent being processed and the environment. They range in complexity from
Level I (general research cabinets for use with low- to moderate-risk
microorganisms) to Level III (totally enclosed cabinets with gas-tight construction that
provide maximum protection to workers and the environment).
Laboratory-acquired infections are Healthcare Associated Infection resulting from
the performance of laboratory activities by staff, regardless of how they occurred.
• Wear new examination gloves when handling blood, body fluids and/or
specimens containing pathogenic microorganisms, and do not touch
telephones, pens, lockers, etc., with gloves on;
• Eating, drinking or smoking is prohibited in the laboratory;
• Food should not be stored in refrigerators used for clinical or research
specimens;
237
• Mouth pipetting is prohibited; use proper mechanical devices (e.g., suction
bulbs);
• Do not open centrifuges while still in motion;
• Always cover the end of blood collection tubes with a cloth or paper towel, or
point them away from anyone’s face when opening;
• Decontaminate work surfaces daily or when contaminated, such as after spills
after being collected with 0.5% chlorine solution;
• Wear protective face shields or masks and goggles if splashes of blood, body
fluids, or fluids containing infectious agents are possible;
• Wear heavy-duty or utility gloves when cleaning laboratory glassware;
• Use puncture-resistant, leak-proof containers for sharps;
• Place infectious waste materials in appropriate plastic bags or containers;
• Wear a laboratory coat while in the laboratory and remove it when leaving the
laboratory (coats should not be worn in non-laboratory areas such as offices,
libraries canteens, etc.);
• Secure the lid of the specimen container tightly;
• Label the specimen clearly with name, date, time of collection and type of
specimen at the site of collection;
• The laboratory should be kept neat clean and free of materials that are not
pertinent to the work.
238
30.0. BLOOD BANKS AND TRANSFUSION SERVICES
Blood banks and transfusion services collect, process, store and provide human
blood intended for transfusion, perform pre-transfusion testing and, finally, infusion
into a patient. The transfusion service, in turn, is responsible for maintaining an
adequate supply of needed blood and blood products, blood-typing and cross
matching patients, and releasing the blood for transfusion. Once the blood is
collected, contamination can be avoided by:
• Maintaining appropriate storage conditions;
• Testing the blood unit without entering the closed collection system;
• Infusing or discarding the blood unit within a short period once the closed
system has been opened.
In this section, the guidelines for the safe provision of Blood Bank and transfusion
services are summarized from the perspective of:
• Screening the blood donor;
• Ensuring the safety of the donor;
• Testing to make sure the blood or blood product is safe for use;
• Protecting the patient receiving the transfusion; and
• Ensuring the safety of laboratory and clinical staff.
30.1. Definitions
Blood Bank. Facility or hospital unit that performs the collection, processing, storage
and distribution of human blood or blood products.
Clinically significant antibody. An antibody capable of producing an adverse
reaction to transfused blood or blood product obtained from a donor (allogenic
antibody) or recipient (autologous antibody).
Closed system for obtaining blood. System in which the blood is not exposed to
air or outside elements during collection and processing, including separation of
components (e.g., platelets) if required prior to transfusion. It is the safest way to
collect process and store blood.
Donor-Patient. Person whose blood is collected for possible transfusion to another
person (allogenic transfusion).
Donor-Recipient. Person whose own blood is collected for possible transfusion to
herself/himself (autologous transfusion).
Look-back system. Process of identifying persons who have received a blood
transfusion from donors who are subsequently found to have infections with HCV,
HIV (and often HBV), and notifying them if appropriate.
Recipient transfusion reaction. Adverse reaction to infusing blood or blood
239
products into a patient (recipient). It may occur at any time during the transfusion but
often happens shortly after starting it. The reaction may be mild or severe and is
rarely fatal.
Transfusion service. Facility or hospital unit that provides storage, pre-transfusion
testing and cross matching, and infusion of blood or blood products to intended
patients (recipients).
Unit of blood. Sterile plastic bag in which a fixed volume of blood is collected in a
suitable amount of anticoagulant. (The collection system should be a closed system,
usually consisting of a sterile hypodermic needle connected by tubing to a collection
bag that has one or two sterile ports for inserting a sterile blood administration set).
Urticarial reaction. Allergic reaction consisting of itching (pruritis), hives, skin rash
and/or similar allergic condition occurring during or following a transfusion blood
product.
240
30.3.3. Blood Storage and Transportation
Blood units must be stored in a refrigerator that can be maintained at temperatures
between 1-6oC (34-46oF). There must be a system to monitor temperatures
continuously and record them at least every 4 hours. In addition, the refrigerator
should have an alarm system that signals by sound before the blood reaches
unacceptable storage temperatures. Blood units exposed to a temperature above the
accepted level for an unknown period should be discarded. To do this:
• Wear examination or utility gloves and protective eyewear;
• Pour contents down a utility sink drain, into a flushable toilet or latrine;
• Place empty blood bags and tubing in a plastic bag or leak-proof, covered
waste container;
• Dispose of plastic bags or contents of the container according to hospital or
facility or facility waste management guidelines.
Blood units transported a short distance (e.g., from the blood bank or transfusion
service to the ward or operating room) require no special handling. Blood should not,
however, be allowed to reach temperatures outside the acceptable range.
241
31.0. PROGRAM MANAGEMENT ON INFECTION PREVENTION AND
CONTROL
Successful programs for preventing the spread of infectious diseases by any route
(body fluids, air, droplet or contact) in healthcare facilities are based on
understanding the scope of the problem, prioritizing activities and effectively using
available resources. Careful planning, implementing and monitoring of activities on a
regular basis are all essential.
HAIs and AMR are important public health concerns in Tanzania. There is conclusive
evidence to show that the establishment of a surveillance system for HAIs and AMR
is associated with reductions in infection rates.
242
Strategies for successful IPC programme
Promoting early detection of infections through surveillance and monitoring
• All levels of healthcare shall promote the use of existing guidelines, through
an awareness raising activities that fully engages patients and service users

infection and implement strategies to reduce infection risk.
– Ensuring protective clothing, disinfectants and other barrier techniques
are available and are used correctly when required.
– Ensuring Laboratory cultures are obtained from designated sites in the
health care facility associated with significant infection risk when indicated.
– WIT and QIT to ensure the health facilities’ IPC plan has a quality
management and improvement program
– WIT and QIT to ensure adherence to Infection control and environmental
cleaning standards in the health facility.
– WIT and QIT to ensure cleaners receive in-service training on cleaning
and use of chemicals and solutions for disinfection.

252
32.0. INFECTION MONITORING
32.1. Surveillance
Surveillance is the monitoring of behaviour, activities, or other changing information
for the purpose of influencing, managing, directing, or protecting people. Surveillance
is used by governments for monitoring health conditions, intelligence gathering, and
prevention of crime, the protection of a process, person, group or object, or the
investigation of crime. It is also used by criminal organizations to plan and commit
crimes, such as robbery and kidnapping, by businesses to gather intelligence, and
by private investigators.
The area of surveillance is increasingly a topic of academic study, including through
research centres, books and peer-reviewed academic journal
Public health problems are diverse including infectious and non-infectious disease.
Surveillance system is a key tool to monitor the situation, identify the problem and
the cause of the problem, to have best interventions, and to evaluate the
effectiveness of the interventions.
The goal of surveillance can be variable depending on its purpose, however, its
general goal is to provide information that can be used for health action by
healthcare or public health personnel, government leaders, and the public to guide
public health policy and programs.
32.1.1. Surveillance of Healthcare Associated Infection
Definition of Surveillance
“The ongoing, systematic collection, analysis, and interpretation of health-related
data essential to planning, implementation, and evaluation of public health practice,
closely integrated with the timely dissemination of these data to those responsible for
prevention and control” (WHO).
Surveillance is also useful in monitoring the effectiveness of preventive and infection
control programs and is required for patient safety. Surveillance of healthcare
associated infections (HAIs) and feedback of the results to QIT is central to efforts to
improve performance.
Output from the surveillance program can be used in the following ways:
• Identify patients and their contacts for treatment and intervention;
• Detect epidemics, health problems, changes in health behaviours;
• Estimate magnitude and scope of health problems;
• Measure trends and characterize disease;
• Monitor changes in infectious and environmental agents;
• Assess effectiveness of programs and control measures;
• Develop hypotheses and stimulate research.
253
Therefore, having surveillance system is essential to control infections in the
healthcare facility setting, as well as in the community setting. Also, keeping good
quality of records and data of targeted disease or conditions is crucial to make
effective implementation practices.
Objectives
The overall aim of surveillance is to provide information that is required to inform
public health actions. The specific objectives and the associated actions are:
• Assessing the quality of healthcare services
– To inform QIT for action in respect of the control and prevention of HAIs
and AMR infections, and the occurrence of disease in the healthcare
setting
• Defining IPC priorities
– To inform policy and planning in respect of the current and likely future
impact of HAIs and AMR infections
• Evaluating IPC programmes
– To inform decisions regarding the status of existing IPC interventions
• Stimulating research
– To generate hypotheses and inform research methodologies
• Detecting outbreaks and exposure
How to start surveillance
• Assess the targeted healthcare population and identify for the outcome or
process of interest
– Outcomes: Healthcare-associated infections
– Processes: Patient care practices aimed at preventing HAI
• Select the outcome or process for surveillance:
– Examples of outcomes: HAI, infection or colonization with a specific
organism, pyrogenic reaction or vascular access infection in
haemodialysis patients, sharp injuries, etc.;
– Examples of processes: Central line insertion practices (CLIPs), surgical
care processes (e.g., preoperative antimicrobial prophylaxis), medication
errors, influenza vaccination rates, hepatitis B immunity rates, personnel
compliance with protocols, etc.;
– Examples of other events: Occurrence of reportable diseases and
conditions, communicable diseases in personnel, organisms or
syndromes indicative of bioterrorist events, etc.
• Determine observation time period
• Choose the surveillance methodology
• Monitor for the outcome or process using standardized definitions for all data
collected
254
• Collect appropriate denominator data, if rates are to be calculated
• Analyse surveillance data
• Report and use surveillance information in a timely manner
Healthcare programmes to prevent Healthcare Associated Infection and the
evidence-based implementation practice have been shown to reduce the occurrence
of HAIs and AMR. Surveillance is an essential element for revealing the current
prevalence of HAIs and AMR to identify potential risk factors and to implement
various preventive strategies.
Routine HAI surveillance in most in-patient healthcare facilities should be conducted
by IPC focal person in an active, patient-based, prospective, targeted manner that
yields risk-adjusted incidence rates.
How is Surveillance Performed?
There are several established components to an active, effective surveillance
system:
1. Planning
Because it is not feasible to monitor all types of infections at all times, choosing
which infections will be surveyed is based upon an initial assessment that will
establish the priorities for the surveillance system. An initial assessment will include:
• the types of patients/residents that are served by the health care setting
• the key medical interventions and procedures that are provided in the health
care setting
• the frequency of particular types of infections within a particular health care
setting
• the impact of the infection (including per cent case fatality and excess costs
associated with the infection)
• the preventability of the infection required mandatory reporting elements
(e.g., antibiotic-resistant organisms, ventilator-associated pneumonia).
2. Data Collection
Collection of infection data for surveillance purposes must be done using validated,
published definitions for HAIs. If the definitions that are used to categorize an
infection are not standardized, a health care setting’s infection rates cannot be
accurately compared to either their own historical infection rates or to external
benchmarks. In order to generate valid HAI rates, information must be collected on
those who are at risk of getting an HAI (denominator) and those who actually
develop an HAI (numerator). Electronic screening of patient records is an emerging
tool for identification of potential HAIs. These computerized systems of case finding
will reduce the time spent by Infection Control Professionals (ICPs) in case finding.
Long-term care homes will have a more limited range of information available for
255
case finding, relying on ongoing contact and feedback from those directly involved in
resident care.
Post-discharge surveillance for surgical site infection is becoming an increasingly
important component of a surveillance system in acute care, due to shorter hospital
stays following surgeries and an increasing proportion of surgeries taking place in
the outpatient setting. Innovative strategies that do not put undue burden on their
program resources are encouraged in hospitals to detect surgical site infections.
3. Data Analysis
The recommendation is to calculate incidence density rates in hospitals and long-
term care homes (i.e., the measurement of new cases of infection (incidence) during
a defined period of risk in the patient/resident population, e.g., length of stay in a
hospital or long-term care and control practices can be implemented to lower the risk
of HAI. Analysis and interpretation of infection data may be done with the facility’s
Infection Prevention and Control Committee or other advisory body to the Infection
Control Team.
HAI rates may be compared to both the facility’s own previous HAI rates and
benchmarks, or to external standards or benchmarks set by other health care
settings. When comparing HAI rates to those of other health care settings, it is
essential that the same case finding methods are used, the same case definitions
are applied and the same methods for risk stratification are employed.
Recommended practice is that a set of peer facilities that serve a similar case mix,
use the same case definitions and similar case finding methods be identified to serve
as a comparison group.
4. Communication of Results
Communication of surveillance data should take place on an ongoing, systematic
basis and be targeted to those with the ability to change infection prevention and
control practice. Communication may be targeted to:
• A health care setting’s Infection Prevention and Control Committee, which
provides an aggregate picture of all infections of interest in the hospital;
• A particular patient/resident care area or specialty care area, focused on the
risk of specific types of infections that are of importance to these groups;
• Patient/resident care staff following the identification of an emerging risk of
infection, to remind or notify of the required precautions in infection prevention
and control;
• Local public health unit when there is a reportable communicable disease
event. home). Where medical devices are inserted and/or surgical procedures
are performed, rates of device-associated or surgical site infection should also
be calculated on an ongoing basis. It may be useful in hospitals to stratify
rates of surgical site infections by standardized risk ratios/rates in order to
compare the rates to other hospitals.
256
An electronic spreadsheet/database and/or statistical analysis program should be
used in hospitals and long-term care homes to store data and calculate HAI rates, to
maximize infection prevention and control resources and reduce the potential for
errors associated with manual calculations.
5. Interpretation of Data
Surveillance data require interpretation to identify areas where improvements to
infection prevention outcomes to which the surveillance system contributes.
Evaluation should include how information produced by a surveillance system is
used to reduce the risk of health care-associated infection. Outcome evaluation
should take place at least annually and a realignment of surveillance objectives
undertaken when indicated.
The steps provided in this best practice guide will assist infection prevention and
control professionals to develop and implement their surveillance programs in a
manner that will permit comparisons with their peers and allow them to quickly detect
early increases in health care-associated infections that may indicate the presence
of an outbreak.
• Active surveillance:
– Health agencies contact health providers seeking reports;
– Ensures more complete reporting of conditions;
– Used in conjunction with specific epidemiologic investigation;
– Trained personnel, mainly IPC focal person, vigorously look for HAI;
– Information accumulated by using a variety of data sources within and
beyond the health facility;
257
• Passive surveillance:
– Diseases are reported by health care providers;
– Simple and inexpensive;
– Limited by incompleteness of reporting and variability of quality;
– Persons who do not have a primary surveillance role, such as ward
nurses or respiratory therapists, identify and report HAI.
B. Patient-based and laboratory-based
• Patient-based:
– Count HAI, assess risk factors, and monitor patient care procedures and
practices for adherence to infection control principles;
– Antimicrobial use and susceptibility patterns;
– Requires ward rounds and discussion with caregivers.
• Laboratory-based
– Detection is based solely on the findings of laboratory studies of clinical
specimens
C. Prospective and retrospective
• Prospective surveillance:
– Monitor patients during their hospitalization;
– For SSIs, also monitor during the post-discharge period;
• Retrospective surveillance;
– Identify infections via chart reviews after patient discharge.
D. Targeted and comprehensive
• Targeted:
– Objectives for surveillance are defined;
– Focus is on specific events, processes, organisms, and/or patient
populations.
• Comprehensive:
– Continuous monitoring of all patients for all events and/or processes;
– Highly personnel resource intensive if done manually.
How to collect data for surveillance
Surveillance data must be accurate and consistent for effective monitoring of trends
and outbreaks. The data collected as part of a surveillance system in a healthcare
setting can be used to identify patients or healthcare workers at high risk for HAIs
and AMR infections or practices associated with a high risk of infection.
Clinical review of medical records should include collecting basic demographic
information (e.g., name, age, date of birth, admission diagnosis), checking for fever,
new antibiotic use, and new cases of diarrhoea, clinical sepsis or the presence of an
inflamed surgical wound, drain or IV site.
258
Discussions with patients (or parents of newborns in this example) should focus on
their health, the health of other young children at home, general hygiene, food
handling and sanitation.
Discussions with staff working in the affected area should deal with ensuring that
recommended patient care activities are being performed both correctly and at the
appropriate times.
Laboratory information to be checked should include a review of positive cultures
and other diagnostic findings if available.
Pharmacy information to be checked prescribed and dispensed antimicrobial.

32.2. Antimicrobial Resistance
260
261
Four Core Actions to Fight Antimicrobial Resistance
1. Preventing Infections, Preventing the Spread of Resistance
Avoiding infections in the first place reduces the amount of antibiotics that have to be
used and reduces the likelihood that resistance will develop during therapy. There
are many ways that food preparation, handwashing, and using antibiotics as directed
and only when necessary. In addition, preventing infections also prevents the spread
of resistant bacteria.
2. Tracking
Gathering data on antibiotic-resistant infections, causes of infections and whether
there are particular reasons (risk factors) that caused some people to get a resistant
infection. With that information, experts can develop specific strategies to prevent
those infections and prevent the resistant bacteria from spreading.
3. Improving Antibiotic Prescribing/Stewardship
Perhaps the single most important action needed to greatly slow down the
development and spread of antibiotic-resistant infections is to change the way
antibiotics are used. Up to half of antibiotic use in humans and much of antibiotic use
in animals is unnecessary and inappropriate and makes everyone less safe.
Stopping even some of the inappropriate and unnecessary use of antibiotics in
people and animals would help greatly in slowing down the spread of resistant
bacteria. This commitment to always use antibiotics appropriately and safely—only
when they are needed to treat disease, and to choose the right antibiotics and to
administer them in the right way in every case—is known as antibiotic stewardship.
4. Developing new Drugs and Diagnostic Tests
Because antibiotic resistance occurs as part of a natural process in which bacteria
evolve, it can be slowed but not stopped. Therefore, we will always need new
antibiotics to keep up with resistant bacteria as well as new diagnostic tests to track
the development of resistance.
