Estimate elective operating-room case capacity from staffed rooms, scheduled hours, average procedure time, turnover time, working days, and a practical utilization factor. The calculator shows daily and monthly case capacity, room cycles, and time reserved as operational buffer. It is designed for scenario planning and does not replace specialty-level block scheduling or clinical case review.
The main result is the estimated number of cases per month at the selected practical factor. The unadjusted cycles-per-room figure is a mathematical ceiling based on average duration.
Case duration varies by specialty and complexity. Emergencies, cancellations, anesthesia time definitions, recovery constraints, staffing, equipment, and block allocation are not inferred.
For 8 rooms, 10 scheduled hours/day, 110 procedure minutes, 30 turnover minutes, 22 days, and an 85% factor:
Use the time interval that actually blocks the operating room and apply that definition consistently.
It is added to procedure time to form one complete room cycle per case.
It reserves time for variability and interruptions that an average-duration ceiling does not capture.
Only for a rough blended scenario; specialty-level calculations are more reliable when durations differ.
Only if you lower the practical factor or scheduled hours to reflect that reserve explicitly.
