OPERATING ROOM MANAGERS are hampered in their efforts to optimize OR efficiency by surgical procedures that last a longer or shorter time than scheduled. The lack of predictability is a result of inaccuracy in scheduling and variability in the duration of procedures. SCHEDULING SHORT PROCEDURES before long procedures theoretically limits this variability. MONTE CARLO SIMULATION of ORs scheduled with various combinations of short and long procedures supports this concept's validity. RESULTS INDICATE that scheduling short procedures first can improve on-time performance and decrease staff member overtime expense without reducing surgical throughput.
手术室经理在优化手术室效率的工作中受到阻碍，因为手术时间比预定时间长或短。缺乏可预测性是由于手术安排不准确和手术时间的可变性造成的。理论上，在长时间手术之前安排短时间手术可以限制这种可变性。对采用短时间和长时间手术各种组合安排的手术室进行蒙特卡洛模拟，支持了这一概念的有效性。结果表明，先安排短时间手术可以提高准时率，减少工作人员的加班费用，而不会降低手术量。
