The use of simulation to reduce the length of stay in an emergency department

Simulating patient flow through an Emergency Department using process-driven discrete event simulation

“…McGuire studied [10] the use of simulation to test process improvement alternatives for reducing the length of stay for ED patients. Another study [15] shows the use of ED simulation studies to perform 'what-if' analysis regarding the effect of process change and staff level change on patients' length of stay. A recent study by Hoot et al [7] has used discrete event simulation in forecasting imminent crowding in the emergency department based on changes in waiting room counts.…”

“…This simulation took past and present patient-level data as input and produced future patient-level data as output. Many of these studies [4,15] used Arena [5], a commercial simulation tool, to obtain their results. Arena is an object-based, hierarchical modeling tool that is used in a wide range of applications.…”

Interacting hospital departments and uncertain patient flows : theoretical models and applications

“…The model described in [4] uses discrete event simulation for a surgical ED which includes a regularcare unit, a semi-intensive care unit, and an intensive care unit (ICU). In addition to the wards, the models in [23,49,132,170] consider the relationship between the ED and DI or the LAB.…”

Simulation analysis of resident and attending physician teaching methods at Kosair Children's Hospital.

“…Jersey. In particular, Samaha, et al (2003) wanted to determine if increasing the department from 10,000 square feet to 25,000 square feet, implementing bedside registration for all patients, or creating a fast-track center would decrease the length of stay. They were able to determine that the fast-track center was the best method to decrease the patient length of stay.…”
