Optimization of the emergency department in hospitals using simulation and experimental design: Case study

摘要

This case study aims at evaluating the impact of different scenario policies drawn from a hospital emergency department committee of experts, using the Delphi method and a literature review, on the Emergency Department (ED) performance. The purpose is to improve Length of Stay (LOS) of patients. Simulation and a Design of Experiment (DOE) were used in order to assess the LOS sensitivities to the selected improving scenarios: Fast Tracking, addition of stretchers for patients under observation, improvement of the waiting times for a consultation with a specialist, improvement of the waiting times for admission, and improvement of the treatment times for patients under observation.
