How the model works
The model converts patient volume into hourly demand, estimates workload from average ESI, and applies the selected patient/staff experience workload threshold to calculate staffing. ED and freestanding ED shifts are modeled as 8 hours. Urgent care volume is divided between two 6-hour periods; the calculator assigns no urgent-care night staffing.
Physician staffing recommendations are shown to one decimal place. A fractional physician can be covered through overlapping shifts rather than requiring the same number of physicians for the entire shift.
Nonphysician practitioners (PAs and NPs) may substitute for physicians in urgent care centers. In emergency departments, they may supplement physician staffing, provided their number does not exceed the number of physicians.
