    Improving Patient Flow Through Axiomatic Design of Hospital Emergency Departments
    (Cranfield University Press, 2009-03-31) Peck, J.; Kim, S-G.; Rajkumar Roy; Essam Shehab
    In response to crowding in hospital emergency departments (ED), efforts have been made to increase patient flow through the Fast Track (FT). The use of FT, however, has not always been accompanied by an increase in the overall patient flow, sometimes leaving the FT underutilized. We find that this is mainly caused by the current practice of assigning patients to FT based only on the Emergency Severity Index. One index for two functional requirements results in a coupling between prioritizing of patients and encouraging the fast flow of them. By introducing a new index for patient flow, we could uncouple this design problem and significantly decrease the overall patient waiting time (~50%) compared to that of the existing use of FT.
