Operating Room Utilization Rate Calculation
Calculate the operating room utilization rate based on used hours and capacity hours. Formula, interpretation, and scientific basis.
Operating room utilization rate
204,5%
Generally considered efficient at 70–85%; very high values indicate delays and loss of flexibility, while low values indicate idle capacity.

Scientific and theoretical basis
Operating room utilization rate (operating room utilization) is a critical operational indicator that shows how efficiently the operating room capacity is being used.
Formula and Logic
Utilization Rate (%) = Used Hours / (Number of Rooms × Daily Hours × Number of Days) × 100
The denominator represents the total operating room hours that can be offered during the period; the numerator represents the actual surgical time used.
How is it interpreted?
The operating room is one of the most expensive resources in the hospital. In the literature, the range of 70–85% is considered efficient and sustainable for most institutions. Very high rates can lead to delays and loss of flexibility for emergency cases, while low rates can result in significant cost losses.
Considerations
The definition of "used hours" (whether it is incision-closure or room entry-exit) must be consistent. Scheduling efficiency and turnover times directly affect the outcome.
Sık Sorulan Sorular
How is the operating room utilization rate calculated?
The used surgical hours are divided by the total operating room capacity hours (rooms × daily hours × days) and multiplied by 100.
What is the ideal operating room utilization rate?
The range of 70–85% is often considered efficient; very high rates may lead to loss of flexibility.
