Differences in surgical site infection rates by state according to state-mandated operating room air changes per hour.
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.
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.
