Using computer simulation to model the expansion needs of the ambulatory emergency care unit at Derriford Hospital

Abstract

Ambulatory emergency care (AEC) units can treat a wide variety of patients referred from the emergency department (ED) and acute general practitioners, helping to ease ED pressures and reduce unnecessary hospital admissions. We developed a simulation model to assess the potential benefi ts of expanding the size and opening times of the AEC unit at Derriford Hospital in Plymouth, both separately and in combination. The model predicted that an expanded size of AEC unit could help to improve the effectiveness of the unit, but not as much as extending the opening hours of the unit, which was predicted to result in a signifi cant impact on the number of patients that can be seen and treated in the AEC unit. The hospital used the evidence generated by the model to support a business to case to extend opening hours of the AEC unit, and open the AEC unit at the weekend.

Using Discrete-Event Simulation to Balance Staff Allocation and Patient Flow between Clinic and Surgery

“…Chalk [11] studied staffing patterns in an ambulatory emergency center (sometimes called "urgent care clinic" in the U.S., to indicate a lower level of care required than a traditional emergency room). Arrival patterns were identified from historic data, and throughput rate as a function of staff availability was calculated.…”

“…[13] study alternative strategies in the medical record department and Easter et al [14] examine the physical design of an emergency department. [15], [16], [17], [18] and [19] also research the emergency department. Regarding resource allocation, Qureshi et al [20] study the ratio of staff to patients.…”
