In Emergency Department (ED) settings, improving productivity, reducing patient waiting time, and increasing
patient safety are important aspects. Decision making (DM) strategies and techniques are crucial to ameliorate
relevant performance measures for these aspects. One critical DM process in EDs is the triage. The information
gathered in triage might be uncertain due to many reasons, e.g., patient subjectivity and no relevant information
available at this stage (e.g., X-rays). Accordingly, in this paper, we present a triage algorithm that uses Fuzzy
Analytic Hierarchy Process (FAHP) along with the Multi-attribute Utility Theory (MAUT) to sort the patients. The
FAHP takes into account the changing relative importance of the vital signs based on the primary complaint; thus,
the status score reflects the severity due to the complaint and the vital sign levels. Three other attributes along with the status score help define the level of criticality: patient’s age, gender and pain level. MAUT is used to aggregate the variables to arrive at a prioritization. We present the application of the proposed methodology using a clinical data set with actual patient information. Our results show multi-faceted improvements achieved through the use of the proposed method in comparison to the triage algorithm currently in place.
