Commonly reported end points for operating room (OR) and surgical scheduling performance are the percentages of estimated OR times whose absolute values differ from the actual OR times by ≥15%, or by various intervals from ≥5 to ≥60 minutes. We show that these metrics are invalid assessments of OR performance. Specifically, from 19 relevant articles, multiple OR management decisions that would increase OR efficiency or productivity would also increase the absolute percentage error of the estimated case durations. Instead, OR managers should check the mean bias of estimated OR times (ie, systematic underestimation or overestimation), a valid and reliable metric.
通常报告手术室 (OR) 和手术安排性能的终点是估计的 OR 时间百分比,其绝对值与实际 OR 时间相差≥15%,或相差各种间隔≥5 至≥60 分钟。我们表明,这些指标是对 OR 性能的无效评估。具体来说,从 19 篇相关文章中,多项可能提高 OR 效率或生产力的 OR 管理决策也会增加估计手术持续时间的绝对百分比误差。相反,OR 管理人员应该检查估计的 OR 时间的平均偏差(即系统低估或高估),这是一个有效和可靠的指标。
