Operational inefficiencies in the use of operating rooms (ORs) are hidden by traditional measures of OR utilization.
To better detect these inefficiencies, the authors defined two new terms, underutilization and overutilization, and illustrated how these measures might be used to evaluate the use of surgical subspecialty ORs.
The authors also described capacity planning (optimizing surgical subspecialty block time allotments) using a minimal cost analysis (MCA) model.
The authors evaluated post boc all surgeries performed over 6 yr at a large teaching hospital.
To prepare utilization estimates, surgical records were categorized relative to budgeted OR block time for each subspecialty.
Surgical cases beginning and ending during budgeted OR block time were categorized as budgeted utilization, budgeted time not used for surgery was underutilization, and cases beginning before/after budgeted block time were classified as overutilization.
Cases that overlapped budgeted and nonbudgeted OR block time were parsed and the portions were assigned appropriately.
Probability distributions were fitted to the historical patterns of surgical demand, and MCA block time budgets were estimated that minimized the costs of underutilization and overutilization for each subspecialty. (...)
