Trust Guideline for the use of the Modified Early Obstetric Warning Score
(MEOWS) in Detecting the Seriously Ill and Deteriorating Woman.
The Modified Early Obstetric Warning Score (MEOWS) has been designed to allow
early recognition of physical deterioration in parturiate women by monitoring their
physiological parameters.. A score >0 triggers the use of a ‘call out cascade’ giving
specific instructions regarding level of monitoring, referral for advice, review, and
immediate actions to be considered (See appendix 2).
Objective
This is to provide guidance for staff within the maternity services on recognising and
monitoring the obstetric patient using the MEOWS chart. The aim is to enable early
recognition of deterioration; advice on the level of monitoring required, facilitate better
communication within the multidisciplinary team and ensure prompt management of
any women whose condition is deteriorating.
Rationale
In the last two ‘Saving Mothers Lives’ reports substandard care was identified where
signs and symptoms were not recognised and acted upon. Both reports
recommended that a national Obstetric Early Warning Scoring system should be
introduced and used for all obstetric women, including those being cared for outside
the obstetric setting (CEMACH 2007, CMACE 2011).
Reduced or altered conscious level is not an early warning sign; it is a red flag
which indicates established illness (MBRRACE 2016)
The physiological changes of pregnancy may render the existing Early Warning
score (EWS) systems inappropriate, (Gopalan PD 2004) and no validated system for
use in the pregnant woman currently exists. Because of this, many maternity
hospitals have developed their own modified EWS system.

Appendix 1 shows the MEOWS adapted for use at the NNUH. These are adapted
from CEMACH 2007 which were studied in the validation study 2011 (Singh 2012).
However, to make consistency with rest of the hospital, a score rather than a
red/amber/green system is used.
The MEOWS is calculated by scoring the values of a full set of observations carried
out routinely by staff which include;
Temperature
Systolic blood pressure
Diastolic blood pressure
Heart rate
Respiratory rate
Level of consciousness using AVPU scale
+/- urine output
A - Alert Alert and conscious
V - Voice Responds to voice
P - Pain Responds to pain
U - No response to voice or pain
Unresponsive
It is the responsibility of the person carrying out the observations to alert the midwife
caring for the woman if the MEOWS score is 1 or more. If the MEOWS is 1-3, it is
then the responsibility of the midwife to decide if increased frequency of observations
or a medical review is needed. If the MEOWS ≥4, or 3 in any single parameter, the
midwife must initiate the call out cascade. This is explained in appendix 2.
Broad recommendations
All obstetric inpatients must have a full set of observations and a MEOWS
calculated at every transfer to a new area (for example on transfer from
Recovery to Blakeney ward). The MEOWS chart used in one area should be
transferred with the patient to the next area in order to help identify changes in
trends of observations.

Antenatal:
Delivery Suite:
All women should have a set of observations and MEOWS recorded on admission to
Delivery Suite or to Triage/MAU. Currently women who are in labour need not have
MEOWS repeated. Regular observations should still be documented on the
partogram as usual.
Recovery:
The theatre care plan will be used in Recovery. The MEOWS chart should be
initiated in recovery by the recovery practitioner prior to transfer to midwifery care.
The last set of observations taken in recovery should be recorded on both the theatre
care and the MEOWS chart.
Postnatal:
All women should have a full set of observations on admission to the postnatal ward
and should have this repeated a minimum of 12 hours apart. A MEOWS score
should be attributed to every set of observations.

The call out cascade (see appendix 2) sets out the action to be taken in response to
individual MEOWS. This should be followed to ensure the appropriate clinicians are
called and appropriate management and care is undertaken. All actions taken must
be clearly documented in the handheld records along with a plan of care.
