Abstract：
Few studies have examined variability in OR utilization across weekdays. We conducted a retrospective analysis to determine OR utilization differences by day of the week and the source and financial effects of any variability. We extracted 55 months of data from a surgical data repository to calculate OR utilization, late starts, idle times, and delays for each weekday. Declines in OR utilization occurred as the week progressed and were attributed to compounding changes in late start, delay, and idle time. The average weekly cost for each OR associated with unused staffed minutes below a target OR utilization of 85% was $19,383, and the comparable lost weekly revenue was $60,256. Perioperative leaders should identify sources of OR utilization variability when developing strategies that enhance outcomes for patients, minimize costs, and maximize revenue.
摘要：
很少有研究检查了工作日OR利用率的变异性。我们进行了回顾性分析，以确定每周的OR利用率差异以及任何变异性的来源和财务影响。我们从手术数据存储库中提取了55个月的数据来计算OR利用率，起步较晚，空闲时间,和每个工作日的延迟。OR利用率随着一周的进展而下降，这归因于后期开始的复合变化，延迟,和空闲时间。与低于目标OR利用率85％的未使用人员分钟数相关的每个OR的平均每周成本为19,383美元，可比的每周收入损失为60,256美元。围手术期领导者在制定增强患者预后的策略时，应确定OR利用率变异性的来源。降低成本，并实现收入最大化。
