AbstractIn this article, a computer simulation study to improve the quality of care at the emergency department at a community hospital in Lexington, Kentucky, is presented. The simulation model is capable of evaluating the quality of care in terms of length of stay, waiting times, and patient elopement and has been validated by being compared with the data collected in the emergency department. Sensitivity analyses have been carried out to investigate the impact of workforce and diagnosis equipment on quality performance. The results suggest that, to ensure better clinical outcome, more nurses are needed; in addition, an additional computed tomography scanner is recommended. The model also shows that implementing team nursing policy (for 2 nurses) could lead to significant improvement in the emergency department's quality of care. Such a model provides a quantitative tool for continuous improvement and flow control in the emergency department and is also applicable to other departments in the hospital.Copyright © 2012 Emergency Nurses Association.
