Title: Using Hospital Admission Predictions at Triage for Improving Patient Length-of-Stay in Emergency Departments

Abstract: Long boarding times have long been recognized as one of the main reasons behind emergency department (ED) crowding. One of the suggestions made in the literature to reduce boarding times was to predict, at the time of triage, whether or not a patient will eventually be admitted to the hospital, and if the prediction turns out to be “admit,” start preparations for the patient’s transfer to the main hospital early in the ED visit. In this talk, we develop a methodology, using logistic regression, Markov decision processes, and queueing theory, that can be utilized for deciding when to request beds early for the patients and investigate the potential benefits of this methodology via a simulation model of an actual ED.
