MANAGING INFECTION RISK INCIDENT TO SURGICAL PROCEDURES IN HEALTH CARE.

FIELD OF THE INVENTION The present invention relates to methods of managing the risk, occurrence, or both ci 10 the risk and occurrence of surgical site infection incident to various surgical procedures.

00 0 The invention also relates to devices for managing such risks, including software-encoded c-I and network delivered devices.

BACKGROUND OF THE INVENTION Over the past number of decades, health care environments have witnessed a nearly forty percent rise in nosocomial infections arising from the delivery of surgical procedures.

This increase persists despite advances in medicine and a reduction in the number and size of hospitals. Many factors are believed to contribute to the infection rise, including the prevalence of larger intensive care units. fewer nurses, the increased severity of patient illness, the increased numbers of immunocompromised patients, and the scarcity of infection control practitioners.

Surgical site infections ("SSIs") repres~nt the third most frequengly reported nosocomial infection, accounting for between 14 and 16 percent of all nosocoinial infections among hospitalized patients. Among surgical patients, SSIs are the most common nosocomial infections accounting for 38 percent of such infections in this population.

The cost of a SSL to a surgical patient can be significant. The incidence of such an infection can result in extended lengths of stay, increased use of antibiotics, added pain, and longer recovery periods. Nosocomial infections also lead directly to 19,000 deaths each year and are a contributing factor to more than 80,000 additional deaths.annually.

SSIs also represent additional costs to the health care system; under the majority of managed care contracts, healthcare systems are not reimbursed for the additional costs of 00

O

S nosocomial infections. Nosocomial infections cost health care systems $4.5 billion per year. On average, a single SSI outbreak costs $3152 and causes an additional 7.3 days of hospital stay.

IO Most importantly, nosocomial infections are usually preventable. With over 27 million surgical procedures performed in the U.S. each year, reducing the risk of SSIs 0 becomes a matter of saving lives. There exists, therefore, a need for an effective and easily It administerable method of managing the risk of nosocomial infections in a health care delivery facility.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT The present invention provides methods and systems for managing the risk and/or occurrence of surgical site infection. In their most essential respect, the methods and systems comprise utilization of a map of health care delivery practices appurtenant to a surgical procedure, or a so-called perioperative process map. These maps can span practices delivered preoperatively, intraoperatively and post-operatively, or can be concentrated on only one or several of the stages of delivery of a surgical procedure. The perioperative maps, once envisioned, can be used in a healthcare environment to 00 effectively manage, and in some embodiments control, the delivery of practices to reduce the risk and occurrence of surgical site infection. In so doing, the methods of the invention tb also impact the ability of a healthcare provider to manage other desired outcomes, including cost reduction, cost control, patient satisfaction, employee health, and employee ID 5 welfare.

According to the invention, a perioperative process map is constructed for a surgical procedure of interest by identifying a plurality of stages for that surgical procedure. Depending on the scope of the desired process map, the stages may include one or more of a preoperative stage, an intraoperative stage, and a postoperative stage.

00 C) 10 Each stage of the procedure includes one or more points-of-care. These points-of-care ci typically comprise one or a plurality of health care practices that are delivered in relatively close proximity to one another either in time or in location. For example, a pre-operative point-of-care may include multiple preoperative activities, including administration of antibiotics, hair removal, etc., while a postoperative point-of-care may include instrument reprocessings; and mechanics of environmental cleaning. While sound health care managrement requires that some delivery activities customarily take place in a given general order, it will be understood that each health care provider may incorporate different activities into its delivery practices, may bundle them differently into different points-of-care, and may place different activities in different sequential relation. For purposes of the present invention, however, a point-of-care for a given health care provider (and for a given surgical procedure) will include olie or more closely related activities drawn together either because of their close relationship to one another in time or in place, or by their commnon purpose pre-surgical patient preparation).

A point-of-care itself, combined with the activities within it, will present one or more measurable sources of infection risk. These sources may be attributable to a fixed environment. For example, the layout and ventilation of a particular surgical suite may present unique (and somewhat unalterable) sources of infection risk, while the relative proximity of the location of the administration of preoperative care to the location of a surgical suite may pose other unique risks. Other sources of risk may be more variable (and more controllable). For example, the time allowed to elapse between the 00 administration of pre-operative regimes and the administration of the surgical procedure.

may be a parameter subject to control.

;The methods and systems of the invention provide a mechanism to align the otherwise disconnected collection. of activities necessary for the performance of a surgical procedure, categorize them according to their shared infection risk, and manage them 0 pursuant to a common protocol for infection risk management.

Figure 1 illustrates a generic perioperative process map according to the invention.

0 The delivery of a surgical procedure a coronary artery bypass graft) is segregated into 00 N number of stages. Stage 1 comprises N points-of-care 10, 20, 30 and 50. Within each 0 0 Point-of-Care N, there is identified N sources of risk 40. Stage 2 comprises a single pointof-care 60 within which there are N sources of risk 70. Similarly, Stage N comprises N points-of-care (80 and 100) comprising various sources of risk, including N sources of risk Figure 2 illustrates another, more specific, example of a perioperative process map according to the invention. Here, the delivery of a surgical procedure is divided into three stages, a preoperative stage 102, an intraoperative stage 104 and a postoperative stage 106.

The pre-operative stage comprises four points-of-care: preoperative assessment 110, operation scheduling 112, surgical patient preparation 114 and patient entry 116. Each of these points-of-care, in turn, comprise one or more activities that pose one or more 0 measurable sources of infection risk. Point-of-care 110 comprises a single source of risk 124. Point-of-care 114 (surgical patient preparation) comprises multiple sources of risk 128. In a similar fashion, the second stage, intraoperative care 104, comprises a point-ofcare 118 (surgery) within which there are seven sources of risk 132. Lastly, postoperative stage 106 comprises two points-of-care. Point-of-care 120 (patient exit) comprises five sources of risk 143 and Point-of-care 122 (patient follow-up) comprises two such measurable risk sources 136. It will be understood that the map of Figure 1 represents and exemplifies the general structure of the perioperative process maps of the invention as applied to one possible scenario in a health care provider's facility. The map provides a tool for. identifying measurable sources of infection risk (that is, those that are generally statistically significant and about which data can be gathered); and aligning those sources along a continuum to set forth, for an individual provider, a generally 00 sequential series of practices that when taken and managed together can be used to manage N and/or control the risk of infection.

tb Figure 3 provides a more detailed illustration of the application of a process map to one stage of a surgical procedure. Stage 300 comprises points-of-care 3 10 and 320. Pointof-care 3 10 comprises sources of risk 330, 340, 350 and 360, and source of risk 330, in turn, comprises practices 370, 380 and 390. Figure 3 thus illustrates the generalized process map as applied, in particular, to one significant source of infection risk. Here, r- prudent health care judgment is applied to identify three practices delivered in one of the 00 points-of-care that contribute to the subject source of risk. These practices are ones about S 10 which data can be generated to identify whether or not the practice or standard was complied with or to identify the relative quality of the delivery of that practice). A more complete perioperative process map would identify a continuum of such practices.

Figure 4 provides an illustration of the generalized map of Figure 3 to one exemplary health care facility. A surgical procedure having a Postoperative stage 400 comprises two points-of-care: Patient exit from the operating room 410 and patient surgical follow-up 420. The patient exit point-of-care has five sources of measurable infection risk: risks realized from instrument reprocessing (430), soiled linen handling and removal (440), environmental cleaning (450), wound management (460) and patient education (470). In the example of Figure 4, four practices are found to contribute to the risks attendant to wound management. These are: proper handwashing (462), administration of sterile dressings (464), dressing changing practices (4,66) and drain removal (468). These practices are felt to govern, in a meaningful and statistically significant way, the risks of infection for wound management in a particular hospital setting. This is not to imply that other practices storage practices of sterile dressing) 2475 are not necessary for proper wound management, nor that such other practices may be found to be significant in another hospital setting.

The methods of the invention are generally adopted after a thorough review of a given health care facility in which the map is to be employed, most typically a traditional hospital environment. This initial review employs a prudent and knowledgeable judgment to ascertain, for a subject facility and for a given surgical procedure, what practices are to be scrutinized and categorized. Typically practices are identified according to one or 00 several of the following characteristics: practices that contribute to or pose a significant risk of infection; practices that are readily measurable and controllable, practices that represent or contribute a significant cost for the health care provider; and practices that affect patient comfort and satisfaction. The practices that ultimately form the basis of the perioperative process map are reviewed for such characteristics and are selected S according to criteria unique to the desires of the intended user. One hospital may accord tn- different weight than another to cost control, or, within a single hospital environment, one C) surgical procedure may be subject to different cost considerations and constraints than 00 another.

Once the practices- are selected according to a desired set of criteria, the practices can be grouped according to their proximity with one another into points-of-care. For example, those practices that are delivered at or about the same time can be grouped together, as can those practices that are delivered in the same place or that are delivered for a common purpose or as a single regimen. Once grouped together, these practices are aligned into points-of-care and stages of care into a perioperative process map in a manner that affords a continuum of practices across one or multiple stages of care. In this way a perioperative process map can be constructed that includes all stages of surgical care, spanning from the time a surgical patient is identified as a candidate for surgery until that patient has fully recovered from the delivery of the surgical procedure and is no longer at risk for surgical site infection. This map may be referred to as a home-to-home map.

The range of possible sources of risk and health care delivery practices subject to the construction of a perioperative process map is large and, as noted above, varies from one health care facility to another and from one surgical procedure to another. It is also important to note that the delivery of a given practice may alone pose a measurable source of infection risk. In such a case, a single practice may be both a source of infection risk and a practice for managing the risk the practice must be done in a manner that minimizes the risk it poses). Alternatively, there may be a single source of risk risk associated with linen handling) that is appropriately managed by multiple practices laundering, use of disposable linens, handling of soiled linens, etc.).

Table 1 below, shows some of the practices and sources of risk associated with a patient undergoing a surgical procedure.

Briefly, according to this aspect of the invention, one or more of the health care delivery practices and/or sources of risk are monitored with one or more compliance indicators. These compliance indicators typically will measure or mark the delivery of the subject practice or practices (or the management of the source or sources of risk) against an accepted standard. A compliance indicator may, for example, ask whether 00 0 or not a practice has been performed, or it may seek a qualified or quantified measure of C- the quality of the performed practice.

Figure 5 illustrates the operation of a perioperative process map according to the .0 invention that incorporates the use of compliance indicators. In Figure 5, Stage of care 500 comprises two points-of-care 510 and 520. Point-of-care 510 comprises in turn four sources of risk 530, 560, 570 and 580. Source of risk 530 is identified as having three practices 532, 542, and 552 that contribute to that risk. For each identified practice a compliance indicator is selected and measured (as indicated by steps 534, 544, and 554).

As noted above, this measurement may take the form of a simple indication that a practice was performed or may represent a selection against a pre-established quality scale a numeric scale from 1 to 10). From these measurements, reports 536, 546 and 556 may be generated. These reports may represent a simple compilation of measurement data. They may also involve or represent manipulation of the raw data, by formula or otherwise, to transform the data into a desired finished or near-finished form. These reports may then be used as inputs to data analyses 538, 548 and 558. Such data analyses can be used in any manner desired by the user. For example, the data compilations may be used simply to monitor compliance with the perioperative process map in real-time, to record historical trends in compliance, to correlate the compliance indicators with one or more indications of a desired outcome infection rate, cost control, or patient satisfaction), or as inputs to one or more feedback process control loops. The data compilations can also be used for multiple such uses.

-12- 00 Figure 6 illustrates one possible application of a system employing compliance N- indicator measurement to a postoperative stage of care. In Figure 6, Postoperative Stage tb 600 comprises two points-of-care 610 and 620, patent exit from OR and patient follow-up respectively. In turn, point-of-care 610 comprises five significant sources of risk, N- 5 instrument reprocessing 630, removal of soiled linen and attire 640, environmental cleaning 650, wound management 660 and patent education 690. Source 660 (wound management) comprises four practices: handwashing 662, dressing application timing 670, dressing application technique 675 and drain removal 680. According to the c-i illustrated embodiment, compliance of each practice is measured and recorded (as 00 S 10 indicated by reference numerals 664, 672, 677 and 682) from which reports are generated c-i (664, 672, 677 and 682) and the resulting data is analyzed (665, 673, 678 and 683) according to the needs and desires of the user.

The methods and systems of the invention can be, in part or in whole, encoded into software or hardware. Thus, devices can be constructed which embody the perioperative process maps of the invention. Such devices may find particular utility in managing and monitoring systems of the invention that employ one or more compliance indicators and/or one or more outcome indicators patient satisfaction, infection rate, etc.). Such software, when used, can be encoded by any known or useful method and can utilize any known or useful software language. Figure 7 shows one possible embodiment of encoded logic. Briefly, in such an embodiment, a practice is evaluated for the significance of the risk it poses. For those risks that are determined topose a significant inf(ection risk, one or more compliance indicators are measured and recorded. The recorded compliance data is analyzed and compared against a standard (or rule). For any practice not incompliance, data is flagge d and action must be taken (the nature of which may be determined by the user) to. clear the flag.

Software-encoded devices may be used as part of an effective risk management program. Such devices can be incorporated into other software regimes, including software that tracks and manages the flow of patients throughout a health care facility.

The software devices of the invention can also be used for remote monitoring of a health care facility, monitoring done for the health care facility by individuals located off- -13- 00 O site from the facility. Such devices could operate across a computer network or via the O2 internet.
