背景资料:手术部位感染(SSI)监测是有效感染控制实践的核心组成部分,尽管其影响尚未大规模量化。目的:确定监测网络中SSI率的时间趋势。方法:SSI监测网络提供了SSI和手术数量的特定程序数据,按医院参与监测的年份分层,来记录参与的时间长度。合并和程序特定的随机效应泊松回归进行,以获得年率比(RR)与95%的置信区间(CI),并包括监测网络作为随机intercept.Findings:36邀请网络,17个网络从15个高收入国家在亚洲,澳大利亚和欧洲参加了这项研究。收集了17种外科手术(心血管、消化、妇产科、神经外科和骨科)的汇总数据,得到了关于5,831,737例手术和113,166例SSI的数据。总体SSI发生率随监测时间显著下降,在纳入的第9年(最终)监测年降低35%(RR:0.65; 95% CI:0.63-0.67)。有很大的变化在程序的具体趋势,但强烈的一致性下降,观察结直肠手术,疝修补术,剖腹产,髋关节假体,膝关节prosthes.Conclusion:在这个大型的,国际队列研究,合并SSI率与一个稳定的和可持续的下降后,加入SSI监测网络;因果关系是可能的,虽然未经证实。手术特异性趋势存在异质性。这些发现支持了监测在降低感染率方面的关键作用,并呼吁在高收入国家广泛实施以医院为基础的SSI监测。(C)2018年,卫生保健感染协会。由爱思唯尔有限公司出版。保留所有权利。
Background: Surveillance of surgical site infections (SSIs) is a core component of effective infection control practices, though its impact has not been quantified on a large scale.Aim: To determine the time-trend of SSI rates in surveillance networks.Methods: SSI surveillance networks provided procedure-specific data on numbers of SSIs and operations, stratified by hospitals' year of participation in the surveillance, to capture length of participation as an exposure. Pooled and procedure-specific random-effects Poisson regression was performed to obtain yearly rate ratios (RRs) with 95% confidence intervals (CIs), and including surveillance network as random intercept.Findings: Of 36 invited networks, 17 networks from 15 high-income countries across Asia, Australia and Europe participated in the study. Aggregated data on 17 surgical procedures (cardiovascular, digestive, gynaecological-obstetrical, neurosurgical, and orthopaedic) were collected, resulting in data concerning 5,831,737 operations and 113,166 SSIs. There was a significant decrease in overall SSI rates over surveillance time, resulting in a 35% reduction at the ninth (final) included year of surveillance (RR: 0.65; 95% CI: 0.63-0.67). There were large variations across procedure-specific trends, but strong consistent decreases were observed for colorectal surgery, herniorrhaphy, caesarean section, hip prosthesis, and knee prosthesis.Conclusion: In this large, international cohort study, pooled SSI rates were associated with a stable and sustainable decrease after joining an SSI surveillance network; a causal relationship is possible, although unproven. There was heterogeneity in procedure-specific trends. These findings support the pivotal role of surveillance in reducing infection rates and call for widespread implementation of hospital-based SSI surveillance in high-income countries.
