Traceability of disinfection in the patient record with an alcohol-based antiseptic agent was a protective factor against the occurrence of SSIs (OR = 0.48, 95% CI [0.24-0.97]).</p><p><strong>Conclusion: </strong>This multimodal study identified significant non-compliance regarding the wearing of caps, masks, and jewellery, as well as patient skin preparation. Obese and diabetic patients, as well as those receiving prophylactic antibiotics other than cefazolin, are particularly at risk for SSIs. Delving deeply into the reasons why professionals disregard recommendations related to operating room attire and antisepsis could be highly beneficial for the prevention of SSIs.</p>","PeriodicalId":7950,"journal":{"name":"Antimicrobial Resistance and Infection Control","volume":"14 1","pages":"118"},"PeriodicalIF":4.4,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12512889/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145273507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
