Impact of surgical checklists on the time of surgical processes: a cross-sectional study

ABSTRACT Objectives: to analyze the impact of the use of checklists on the mean time of the operative processes of patients undergoing hip and knee arthroplasties. Method: cross-sectional and analytical research conducted between November/2020 and March/2022 with retrospective consultation in a simple random sample of 291 medical records, distributed in three periods (2010/2013/2016). Descriptive and inferential statistics were used for data analysis; p=0.05 values indicated significance. Results: there was a reduction in the time of entry-exit from the operating room (p=0.002), surgery (p<0.001) and between the onset-anesthesia and the beginning-incision (p=0.021). There was no difference in time between patients with and without the use of checklists (p=0.05) in relation to the variables onset-anesthesia, onset-incision, time of anesthesia and surgery. Conclusion: the implementation of checklists potentially contributed to reduce the time of use of the operating room. The nonassociation of its use with the increase in the mean time of the processes in the operating room shows that its application does not interfere negatively in this indicator.

摘要
目的：分析核查清单使用对接受髋膝关节置换术（hip and knee arthroplasties）患者手术流程平均时长的影响。
方法：本研究为分析性横断面研究，于2020年11月至2022年3月间开展，对291份简单随机抽样的病历进行回顾性查阅，样本按2010年、2013年、2016年三个时间段分组。数据分析采用描述性统计与推断性统计方法，以p≤0.05作为统计学显著性检验标准。
结果：研究显示，患者进出手术室（operating room）时长（p=0.002）、手术总时长（p<0.001）以及麻醉诱导至切皮开始的间隔时长（p=0.021）均显著缩短。但在麻醉诱导时长、切皮时长、麻醉时长及手术时长方面，使用与未使用核查清单的患者组间无统计学差异（p=0.05）。
结论：核查清单的实施可有效缩短手术室使用时长。本研究未发现核查清单使用与手术室流程平均时长增加存在关联，表明其应用不会对该指标产生负面影响。
