Dedicated orthopedic operating room unit improves operating room efficiency

J Arthroplasty. 2013 Aug;28(7):1066-1071.e2. doi: 10.1016/j.arth.2013.01.033. Epub 2013 Mar 27.


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.

Keywords: operating time; procedure time; throughput; total hip arthroplasty; total knee arthroplasty; turnover time.
