Abstract

This paper presents a simulation model of the operations in the Emergency Department (ED) and Medical Telemetry (Med Tele) Units at Rush North Shore Medical Center. The model allows management to see the operations of both units as well as how the processes of each unit impact the other. Due to the large amount of variability that can take place within these units, Rush North Shore Medical Center along with Cap Gemini Ernst & Young sought the use of simulation to help evaluate their operations and provide insight into possible areas for improvement. Rockwell Automation created a model which depicts the current operations and evaluates possible alternatives to reduce the length of stay in the ED and improve operations. Using simulation, the hospital was able to select two to three key changes, rather than creating more stress with ten or more changes, to get the same result.
