Audit of antibiotic prophylaxis and adherence of surgeons to standard guidelines in common abdominal surgical procedures

Abstract

Background: Prophylactic use of antibiotics before surgery is evidence-based practice for prevention of surgical site infections (SSIs). Aims: To investigate adherence to and surgeons’ perception of antibiotic prophylaxis guidelines. Methods: A two-phase, cross-sectional prospective study conducted in two teaching hospitals. Phase 1: 6-month audit of prescriptions to investigate adherence rate to evidence-based guidelines. The important information was collected from medical charts through a predesigned proforma. Phase 2: self-administration questionnaire was used to investigate the surgeons’ perception. Descriptive statistics, independent-sample Kruskal–Wallis test and multivariate linear regression analysis were performed using SPSS version 21.0. Results: A total of 866 eligible surgical cases (acute appendectomy; n = 418; 48.2%), laparoscopic cholecystectomy (n = 278; 32.1%) and inguinal hernia (n = 170; 19.7%) were investigated. Surgical antibiotic prophylaxis was prescribed in 97.5% of procedures. Out of these, 9.5% adhered to guidelines with respect to correct choice, 40% for timing, and 100% for dose and route (optimal value 100%). Most patients received ceftriaxone (n = 503; 59.5%) as prophylactic antibiotic. The questionnaire (good internal consistency; α ≥ 0.7) was filled out by 200 surgeons. More than half (69%) of participants thought that antibiotics were overused. Most surgeons perceive that poor adherence to treatment guidelines is due to poor awareness, underestimation of infection, lack of consensus, and disagreement with guidelines recommendations. Conclusions: Surgeons have positive perception that antibiotics should be used according to guidelines recommendations. However, we found poor treatment adherence to antibiotic prophylaxis guidelines.
