Measure how fully a hospital’s staffed bed capacity is used over a selected period. Enter staffed beds, occupied bed-days, days in the period, and planned downtime to compare demand with effective capacity. The calculator shows utilization, average daily census, unused bed-days, and the extra occupied bed-days that would reach a chosen planning target without treating that target as a universal clinical standard.
Utilization describes use of effective staffed capacity, while average daily census describes the average occupied beds. A higher percentage is not automatically better: sustained high utilization can reduce flexibility for peaks, isolation needs, and admission timing.
The entered planning target is user supplied. This tool does not prescribe a safe occupancy threshold or account for bed type, isolation capability, staffing by shift, or demand variation.
With 40 staffed beds, 900 occupied bed-days over 30 days, and 2% unavailable capacity:
Use your reporting definition consistently, typically one occupied staffed bed for one census day.
Use staffed beds that were actually available for assignment during the period.
It can if the inputs are inconsistent or temporary overflow capacity is missing. Reconcile bed definitions and the reporting period.
No. The target is editable because appropriate planning levels depend on demand variability, unit type, and local policy.
Represent planned or average unavailable capacity with the downtime input, or reduce the staffed-bed count if beds were closed for the entire period.
| Measure | Formula | Use |
|---|---|---|
| Bed-days | Beds × days | Total time capacity |
| ADC | Occupied bed-days ÷ days | Average census |
| Utilization | Use ÷ effective capacity | Capacity loading |
