ABSTRACT
BACKGROUND:
After a Department of Health site visit, 2 teaching hospitals imposed strict regulations on operating room attire, including full coverage of ears and facial hair. We hypothesized that this intervention would reduce superficial surgical site infections (SSIs). STUDYDESIGN:
We compared NSQIP data from all patients undergoing operations in the 9 months before implementation (n = 3,077) to time-matched data 9 months post-implementation (n = 3,440). Univariate and multivariable analyses were used to examine patient, clinical, and operative factors associated with SSIs. Power analysis was performed using pre-intervention SSI rates.RESULTS:
Despite a shift toward more clean cases, there were more SSIs post-implementation (33 vs 30 [1%]; p = 0.95). There were no differences in length of stay, complications, or mortality between the 2 time periods. Overall, SSI increased with wound class 0.6%, 0.9%, 2.3%, and 3.8% in clean, clean-contaminated, contaminated, and infected cases, respectively. Limiting the review to clean or clean-contaminated cases, incisional SSIs increased from 0.7% (20 of 2,754) to 0.8% (24 of 3,115) (p = 0.85). A multivariable analysis showed that implementation of these policies was not associated with decreased SSIs (odds ratio 1.2; 95% CI 0.70 to 1.96; p = 0.56). The largest predictors of SSIs were preoperative infection, operative time >75th percentile, open wounds, and dirty/contaminated wounds. A hypothetical analysis revealed that a sample size of 485,154 patients would be required to demonstrate a 10% SSI reduction among patients with clean or clean-contaminated wounds.CONCLUSIONS:
Implementation of stringent operating room attire policies do not reduce SSI rates. A study to prove this principle further would be impractical to conduct.
