Due to the high maintenance costs, it is critical to make full use of operating rooms (ORs). Operative duration is an important factor that guides research on surgery scheduling. Clinical effects, for example, surgery type, rationally influences operative duration. In this study, we also investigate whether the planning and scheduling decisions in ORs influence the operative duration.
For our study, we collected and reviewed data on 2,451 thoracic operations from a large hospital in China. The study was conducted over a period of 34 months. Linear and nonlinear regression models were used to detect the effects on the duration of the operations. We have also examined interactions between the factors.
Operative duration decreased with the number of operations a surgeon performed in a day ( < 0.001). It was also found that operative duration decreased with the number of operations allocated to an OR, as long as there were not more than four surgeries per day ( < 0.001). It was also found that operative duration decreased with the number of operations allocated to an OR, as long as there were not more than four surgeries per day ( < 0.001). It was also found that operative duration decreased with the number of operations allocated to an OR, as long as there were not more than four surgeries per day (.
Operative duration was affected not only due to clinical effects but also some nonclinical effects. Scheduling decisions significantly influenced operative duration.
由于维护成本高，充分利用手术室至关重要。手术持续时间是指导手术安排研究的一个重要因素。临床效果，例如手术类型，合理地影响手术持续时间。在本研究中，我们还研究了手术室中的规划和调度决策是否会影响手术持续时间。
在这项研究中，我们从中国一家大型医院收集并回顾了 2451 例胸部手术的数据。该研究持续了 34 个月。使用线性和非线性回归模型来检测对手术持续时间的影响。我们还检查了因素之间的相互作用。
手术持续时间随着外科医生每天完成的手术数量的增加而减少（<0.001）。我们还发现，只要每天的手术不超过 4 台，手术持续时间就会随着分配给手术室的手术数量的增加而减少（<0.001）。只要每天的手术不超过 4 台，手术持续时间就会随着分配给手术室的手术数量的增加而减少（<0.001）。只要每天的手术不超过 4 台，手术持续时间就会随着分配给手术室的手术数量的增加而减少（<0.001）。
手术持续时间不仅受到临床效果的影响，还受到一些非临床效果的影响。调度决策对手术持续时间有显著影响。
