我们使用蒙特卡罗计算机模拟来确定手术或麻醉干预是否可以创造足够的新的开放手术室(OR)时间，以允许在正常工作时间内在OR病房完成额外的病例。我们使用了安排案件的规则，假设OR人员得到补偿，以便OR套件可以通过缩短案件持续时间来在正常安排的时间内完成额外的案件，从而在经济上获利。创建足够的新打开的OR时间以可靠地(大于或等于95%)安排另一个案例所需的每个案例的持续时间对于具有1-15个ORs和平均案例持续时间为1、2或3小时的OR套件分别减少30-39分钟、79-110分钟和105-206分钟。影响：计算机模拟显示，缩短病例持续时间不太可能创造足够的手术室时间来可靠地允许在工作时间内安排额外的病例完成。通过优化病例调度，而不是减少套房中所有病例的持续时间，可以最好地将其他病例添加到手术室套房时间表中。
We used Monte-Carlo computer simulation to determine whether surgical or anesthetic interventions to achieve small decreases in case duration may create enough new open operating room (OR) time to permit an additional case to be scheduled for completion in an OR suite during regular working hours. We used rules for scheduling of cases assuming that OR personnel are compensated so that the OR suite can profit financially from decreasing case duration to complete an additional case during regularly scheduled hours. The decreases in each case's duration required to create enough new open OR time to reliably (greater than or equal to 95%) schedule another case were 30-39 min, 79-110 min, and 105-206 min for OR suites with 1-15 ORs and mean case durations of 1, 2, or 3 h, respectively. Implications: Computer simulation shows decreasing case duration is unlikely to create sufficient operating room time to reliably permit an additional case to be scheduled for completion during working hours. Additional cases may best be added to the operating room suite schedule by optimizing case scheduling, not by decreasing the duration of all cases in the suite.
