BACKGROUND: Optimizing surgical trays to improve operating room efficiency and reduce costs in instrument processing is an under-appreciated strategy for cost containment. This study aimed to assess the economic impact of instrument tray optimization in total joint arthroplasty.
METHODS: Thirty-five randomly selected elective primary total knee arthroplasty and total hip arthroplasty performed by 4 fellowship-trained surgeons were analyzed. Type and number of instruments used as well as timing of different steps in the sterilization process were recorded by an independent observer. Using Lean methodology, surgeons identified redundant or underutilized instruments and agreed upon the fewest number needed for each tray. Instrument utilization rates and processing time were analyzed before and after tray modifications. Annual cost savings were calculated based on a processing factor of $0.59-$11.52 per instrument.
RESULTS: Only 45.5% of instruments opened for total knee arthroplasty were utilized. After optimization, 28 of 87 (32.2%) instruments were removed and the remainder could be stored in one tray. Mean set-up time decreased from 20.7 to 14.2 minutes, while 40-75 minutes were saved during the sterilization process. For total hip arthroplasty, only 36.0% of instruments were utilized. Using Lean methods, 46 of 112 (41.1%) instruments were removed and tray count was reduced to 2 trays. Mean set-up time decreased from 27.9 to 18.6 minutes, while 45-150 minutes were saved during processing. Average annual savings amounted to $281,298.05.
CONCLUSION: Lean methodology can be used to eliminate redundant or underutilized instruments in total joint arthroplasty, improving surgical efficiency and generating substantial cost savings.
