Adherence to guidelines of antibiotic prophylactic use in surgery: a prospective cohort study in North West Bank, Palestine

Background: Surgical site infection is a major contributor to increased mortality and health care costs globally which can be reduced by appropriate antibiotic prophylactic use. In Palestine, there is no published data about preoperative antibiotic use. This study aims to find the pattern of antimicrobial prophylaxis use by evaluating time of the first dose, antibiotic selection and duration after surgery in three governmental hospitals in North West Bank/Palestine during 2011. Methods: After approval of Institutional Review Board, a prospective cohort study included a total of 400 abdominal, orthopedic, and gynecological operations which were performed during study period. Trained clinical pharmacists observed selected 301 operations and followed the patient's files for the three intended study parameters. Compliance of prophylactic antibiotic administration was evaluated according to published guidelines of the American Society for Hospital Pharmacist. Data were analyzed using SPSS version 16 applying descriptive methods. Relationship between guideline compliance and selected operation factors such as type of surgery, patient care unit, and hospital shift, in addition to provider's age, gender, experience, and specialization were examined applying chi square test. The statistically significant factors with p < 0.01 were further analyzed using logistic regression model. Results: Overall compliance for the studied parameters was very low (2%); only 59.8% received their first dose in appropriate time, 18.5% had appropriate antibiotic selection, and 31.8% of patients received antibiotic in appropriate duration. The OBGYN department had much better compliance regarding timing and duration of antibiotic use (P < 0.001), however the proper antibiotic selection was best adhered to for the abdominal surgeries (OR = 3.64, P = 0.002). Male providers were statistically significantly much less adherent to the timing of antibiotic dose (OR = 0.28, p < 0.001), but better adherent in antibiotic selection (OR = 0.191, p = 0.028). Anesthetic technicians showed higher compliance than nurses in timing and duration of antibiotic use. Conclusions: Lack of guidelines explains the low adherence to appropriate surgical antibiotic prophylaxis in Palestine, with high rate of broad spectrum antibiotic use, long duration and inappropriate time of first dose. We recommend adopting guidelines for prophylaxis and training all health care providers accordingly.
