Abstract

Background: Air changes per hour (ACH) in operating rooms (ORs) are energy intensive, and optimal air change settings are not known.

Objectives: We sought to explore whether there is a relationship between surgical site infections (SSIs) across states based on their state-mandated ACHs.

Design: Ecological, descriptive, cross-sectional study of publicly reported SSI data in the United States.

Methods: Wilcoxon test was used to investigate differences between SSI rates for specific surgery types between ACH mandate levels (15 and 20 ACH). Uni- and multivariable Poisson models at the state level were fitted to estimate differences in SSI rates for each surgery type.

Results: OR ACH mandates and SSIs were positively correlated for C-sections and spinal fusion; negatively correlated for colon and laminectomy surgery.

Conclusion: For most surgery types, there is no correlation between state-mandated OR ACH. Further studies are needed to determine what changes to mandates can be made safely and effectively.

根据国家规定的手术室每小时换气次数，各州手术部位感染率的差异。

背景：手术室（or）的每小时换气次数（ACH）是能源密集型的，最佳换气设置尚不清楚。目的：我们试图探讨是否存在的关系，手术部位感染（ssi）跨州基于其国家规定的ACHs。设计：对美国公开报道的SSI数据进行生态、描述性、横断面研究。方法：采用Wilcoxon检验调查不同ACH授权水平（15和20 ACH）的特定手术类型SSI率的差异。拟合州一级的单变量和多变量泊松模型来估计每种手术类型的SSI率差异。结果：剖宫产和脊柱融合术中OR ACH指令与ssi呈正相关；与结肠和椎板切除术负相关。结论：对于大多数手术类型，国家规定的OR与ACH没有相关性。需要进一步研究，以确定可以安全有效地对任务作出哪些改变。

期刊介绍： Antimicrobial Resistance and Infection Control is a global forum for all those working on the prevention, diagnostic and treatment of health-care associated infections and antimicrobial resistance development in all health-care settings. The journal covers a broad spectrum of preeminent practices and best available data to the top interventional and translational research, and innovative developments in the field of infection control.
