BackgroundIn an effort to reduce surgical site infection (SSI) rates, a large number of infection control practices (ICPs), including operating room attire policies, have been recommended. However, few have proven benefits and many are costly, time-consuming, and detrimental to provider morale. The goal of this multi-institution study was to determine which ICPs are associated with lower postoperative SSI rates.Study DesignTwenty American College of Surgeons NSQIP and Texas Alliance for Surgical Quality-affiliated hospitals completed this Quality Improvement Assessment Board-approved study. Surgeon champions at each hospital ranked current surgery, anesthesia, and nursing adherence to 38 separate ICPs in 6 categories (attire, preoperative, intraoperative, preoperative, intraoperative, antibiotics, postoperative, and reporting) on 4-point scales for general surgery cases. These data were compared with the risk-adjusted general surgery SSI odds ratios contained in the July 2016 American College of Surgeons NSQIP hospital-level, risk-adjusted reports. Compliance rates were compared between the 7 best (median SSI odds ratio, 0.64; range, 0.56 to 0.70) and 7 worst (median SSI odds ratio, 1.16; range, 0.94 to 1.65) performers using ANOVA.ResultsNearly all hospitals reported maximal adherence to hair removal with clippers (Surgical Care Improvement Project measure Inf-6) and to best-practice prophylactic antibiotic metrics (Surgical Care Improvement Project measure Inf-1-3). Variable adherence was identified across many ICPs and more frequent compliance with 8 ICPs correlated with lower SSI odds ratios, including preoperative shower; skin preparation technique; using clean instruments, gowns, and gloves for wound closure and dressing changes; and transparent internal reporting of SSI data. Operating room attire ICPs, including coverage of nonscrubbed provider head and arm hair, did not correlate with SSI rates.ConclusionsThis analysis suggests that the subset of ICPs that focus on perioperative patient skin and wound hygiene and transparent display of SSI data, not operating room attire policies, correlated with SSI rates. Implementation of this subset of evidence-based ICPs may improve SSI rates at lower-performing hospitals.Copyright © 2017 American College of Surgeons. Published by Elsevier Inc.
