Description

UCL School of Management is delighted to welcome Ohad perry, Northwestern, to host a research seminar discussing ‘Queueing Models for Patient-flow Dynamics in Internal Wards’.

Abstract 

Hospital queues have unique features, which are not captured by standard queueing assumptions, necessitating the development of specialized models. In this talk, I will present a queueing model for patient-flow dynamics in large Inpatient Wards (IWs), and its implementation in Northwestern Memorial Hospital (NMH), which is a large academic hospital in Chicago. That queueing model is designed to take into account the most salient features of queues associated with large IWs, including the need for a physician’s approval to discharge patients, and subsequent discharge delays. The study begins by characterizing the maximum achievable patient throughput, and proceeds by introducing a deterministic (fluid) approximation for the non-stationary patient-flow dynamics. I will then demonstrate the effectiveness of the model by comparing its predictions to data from NMH and an Israeli hospital, and present a toolbox we developed for hospitals’ use. Time permitting, I will introduce our work with the Labor-and-Delivery Unit at NMH.
