Utility Function Based Patient Prioritization in the Emergency

 

Gül E. Okudan Kremer, The Pennsylvania State University

 

 

Abstract

 

With the increased awareness of productivity problems in healthcare operations, many researchers have proposed the implementation of tools and methods developed in other fields to benefit healthcare delivery. Accordingly, in this talk we present an application of a decision making methodology, the multi-attribute utility analysis, to healthcare. The sample problem presented as part of the application involves patient prioritization in an emergency department (ED), where several patients require immediate attention and they all have the same acuity level. Utility theory is selected for this application to appropriately account for the uncertainty in the decision problem. Further, integration of the decision-making system with RFID technology is discussed to bring dynamicity to the decision-making approach.

 

In order to recognize who is most in need of care, most EDs utilize a triage system to sort patients by severity of illness or injury. The triage is a dynamic process in decision-making, where patients are prioritized according to their medical condition and chance of survival on arrival at the ED. This system inevitably results in waiting periods, especially for those with less acute problems. Due to under-staffing in many EDs, triage assessment can be done only once for most patients. This is a serious concern since patients’ conditions change over time, and not having current information will result in less than optimum care. Accordingly, we are experimenting with dynamic vitals monitoring, and thereby providing dynamicity to the usage of MAUT for the prioritization. Currently, we are collecting data from three hospitals: Hershey Medical Center, Mount Nittany Medical Center, and Williamsport Susquehanna Hospital. During the talk, challenges and opportunities of working with healthcare institutions will also be covered.
