Abstract

Disruption to the circadian clock has impacts on health and wellbeing, including impaired immune function and wound healing. It is plausible that the timing of surgical procedures could impact the body's response to trauma and susceptibility to infections. Using the Health Quality & Safety Commission data on surgical site infections (SSI) we sought to investigate any possible time of day effects on the incidents of recorded infections. All recorded data from June 2017 to July 2021 were extracted for cardiac and orthopaedic operations in New Zealand. The incidence of SSI was calculated for each 4-hour bin of time across the day. There was a total of 87,034 cases in the analysis, of which 1,327 (1.5%) had an infection. Univariately, there was a significant time of day effect, with operations after 8 pm being 3.91 times more likely to have an infection (p<0.001), and operations between 4 pm and 8 pm being 0.71 times more likely (p=0.03) to have an infection compared to operations conducted between 12 pm and 4 pm. However, when age, acuity and American Society of Anesthesiologists score were included in the model, there were no differences in the rate of infection by time of day. This preliminary work suggests that surgical time of day does not significantly impact incidence of surgical infection when other variables are controlled for. However, this work has not considered other factors that may also be important. We plan to link the SSI data with the National Minimum Dataset to investigate these other factors and conduct a more comprehensive analysis.

手术时间和手术部位感染的影响。
生物钟紊乱会影响健康和福祉,包括免疫功能受损和伤口愈合。手术的时机可能会影响身体对创伤的反应和对感染的易感性,这似乎是合理的。使用卫生质量和安全委员会关于手术部位感染(SSI)的数据,我们试图调查一天中任何可能的时间对记录感染事件的影响。2017年6月至2021年7月的所有记录数据均用于新西兰的心脏和骨科手术。计算一天中每4小时的SSI发生率。共分析87034例,其中1327例(1.5%)发生感染。单就时间而言,有显著的影响,晚上8点之后的手术感染的可能性是3.91倍
