Key result
Operative duration decreased with the number of operations a surgeon performed in a day (P<0.001) and with the number allocated to an operating room up to four per day (P<0.001).
Why the study?
Because operating room maintenance costs are high and operative duration guides surgery scheduling, this study investigated whether planning and scheduling decisions influence operative duration alongside clinical factors.
Population
2,451 thoracic operations from a large hospital in China

Scheduling decisions, such as the number of operations per surgeon and per operating room, significantly influence operative duration in thoracic surgery.
Wang et al. (2020) conducted an observational in Thoracic surgery (n=2,451). Planning and scheduling decisions (e.g., number of operations per surgeon/OR, sequencing) was evaluated on Operative duration (p=<0.001). Operative duration decreased with the number of operations a surgeon performed in a day (P<0.001) and with the number allocated to an operating room up to four per day (P<0.001).
