We investigated the effectiveness of dedicated orthopedic operating rooms (OR) on minimizing time spent on perioperative processes to increase OR throughput in total knee and hip arthroplasty procedures. The use of a dedicated orthopedic unit that included 6 ORs with staff allocated only for those ORs was compared to the use of a traditional staffing model. After matching to simulate randomization, each group consisted of 422 procedures. The dedicated orthopedic unit improved average anesthesia controlled time by 4 minutes (P<.001), operative time by 7 minutes (P=.004) and turnover time by 8 minutes (P<.001). An overall improvement of 19 minutes per procedure using the dedicated unit was observed. Utilizing a dedicated orthopedic unit can save time without increasing adverse events.
