| Abstract: | We explored whether there were large differences in operating room (OR) times for two common procedures performed by multiple surgeons at each of several hospitals thousands of miles apart. Mean OR time, “wheels in” to “wheels out,” for ten consecutive cases of each of laparoscopic cholecystectomy and lung lobectomy were obtained for each of ten hospitals in eight countries from their OR logs. After log transformation, the OR times were analyzed by analysis of variance. Mean OR times differed significantly among hospitals (P = 0.006, laparoscopic cholecystectomy; P < 0.001, lung lobectomy). The second longest average OR time was 50% longer than the second shortest average OR time for both laparoscopic cholecystectomy and lung lobectomy. Differences in OR times among the hospitals we studied were large enough to affect the productivity of OR nurses and anesthesia providers. Thus, international benchmarking studies to understand differences in OR times worldwide may be beneficial. Franklin-Dexter@Ulowa.edu; www.FranklinDexter.net Financial disclosure. F.
