[Evaluation of surgical antibiotic prophylaxis in a Tunisian University Hospital].

Antibiotic prophylaxis (ATBP) is one of the specific measures for the prevention of surgical site infections, whose impact has been quantified in clean or clean-contaminated surgery. Our study aims to evaluate the conformity of ATBP practices and the adherence to the prescribing protocols adopted in our Hospital. We conducted a clinical audit retrospective observational study, evaluating antibiotic prophylaxis practices in our Hospital in the month of March 2015. The primary study endpoint was the overall compliance of the observed practices with the 5 major criteria defined by the French National Authority for Health (FNAH). We followed the guidelines of the French Society of Anesthesia and Intensive Care published in 2010. The study included 150 patients who had undergone surgery in the Department of General Surgery, Orthopaedics and Urology. The overall compliance rate was 33.3%. The compliance with each of the 5 major criteria defined by the FNAH was 74% for the indication; 84% for the time between injection and incision; 60% for the choice of ATB; 89.3% for the dose of the first injection and 72% for the duration of ATBP. The compliance was variable depending on the Department; better compliance was reported in the Department of Urology, in scheduled surgery and when the prescriber was an anesthetist-resuscitator. A global strategy including organization, education and restriction, could lead to a real improvement in the rate of compliance with ATBP practices. Successive audits should be carried out regularly in order to evaluate the impact of the undertaken actions.
