Calculate emergency department treatment-room utilization from daily visits, average room-occupied time, staffed rooms, and operating hours. The tool compares used room-hours with staffed room-hours and shows average occupied rooms, spare room-hours, and the visit volume corresponding to a user-entered planning target. It measures space loading only; staffing, acuity, boarding, and demand peaks still need separate review.
The result is the share of staffed room-time consumed by the entered daily workload. Average occupied rooms helps translate the percentage back into a physical-space measure.
A daily average can hide severe hourly congestion. This tool does not prescribe a safe utilization target and does not model room type, isolation, cleaning variation, boarding, or staffing constraints.
For 95 visits/day, 165 occupied minutes per visit, 16 staffed rooms, and 24 operating hours:
Include cleaning or turnover minutes if the room cannot accept another patient during that time.
Yes when they continue to occupy a treatment room; use the full blocked time in your workload data.
A result above 100% means the inputs describe more room-hours than the stated staffed capacity and should be reconciled.
No. It is a user-entered comparison point, not a clinical or regulatory standard.
It converts total room-hours into an intuitive average, though it still does not show peak simultaneous occupancy.
| Measure | Formula | Unit |
|---|---|---|
| Used time | Visits × room time | Room-hours/day |
| Available time | Rooms × operating hours | Room-hours/day |
| Average occupied rooms | Used hours ÷ operating hours | Rooms |
