Objective:
To analyze the contribution of nonprocedural operating room (OR) times to transurethral resection of bladder tumor (TURBT) operative efficiency.
Methods:
Over a 24-month period, all nonprocedural OR times from TURBT surgeries performed at a single institution were prospectively collected. Nonprocedural times included: in-room to anesthesia release time, anesthesia release to cut time, and close to wheels out time. Procedural OR time was cut to close time. We also analyzed the impact of time of day on TURBT efficiency (morning vs afternoon). Comparisons between groups were made using the Wilcoxon rank sum test for continuous variables.
Results:
We identified 777 consecutive TURBT procedures from 2019 to 2020. The median total OR time was 63 minutes (interquartile range: 50-81 minutes). The nonprocedural time occupied a median of 49.4% of the total operating time (interquartile range: 38.9%-60.4%). Median anesthesia release to cut time was slower when 1 TURBT was performed a day compared to 2 or more (13 minutes vs 12 minutes, P = .04). Median close to wheels out time was faster when there was 1 TURBT in a day (7 minutes vs 8 minutes, P = .02). Median in-room to anesthesia release time was faster in the morning than it was in the afternoon (10 minutes vs 11 minutes, P = .02).
Conclusion:
Nonprocedural times made up roughly half of the total TURBT operating time and should be considered in OR efficiency analyses. TURBT OR efficiency may be related to the number of TURBTs performed in a day as well as the time of day of TURBT start.
