Operating room (OR) scheduling is one of the most important tasks for hospital managers in terms of improving efficiency in hospitals. In this study, scheduling policies for elective and emergency procedures that minimize the total expected cost of OR operations are investigated. A simulation optimization approach is used to develop schedules and evaluate the operational impact of reserving capacity for emergency patients in an OR system. In order to mitigate the possible negative effects of unused capacity should a lower than expected number of emergency cases arrive, assigning any unused capacity to standby patients is examined. This study looks at the effect of hospital size in terms of the number of surgeries performed, mean surgery duration, and the variability in surgery duration on scheduling policy based on empirical data from three hospitals. Specifically, we investigate the best policies in terms of OR efficiency with and without reserved capacity for emergency arrivals and different probabilities for standby patient availability.

用于手术室调度的预留容量策略

就提高医院效率而言,手术室(OR)调度是医院经理最重要的任务之一。在本研究中,研究了用于选修和应急程序的调度策略,该策略将OR操作的总预期成本降至最低。模拟优化方法用于制定时间表并评估在OR系统中为急诊患者预留容量的操作影响。为了减轻未使用容量的可能的负面影响(如果到达的紧急情况数量少于预期),将检查将任何未使用容量分配给待命患者。这项研究从手术数量,平均手术时间,根据三家医院的经验数据,制定手术计划时的手术时间差异。具体来说,我们会根据OR效率研究最佳策略,无论是否具有为紧急情况到达预留的容量,以及为待命患者提供服务的可能性都是不同的。
