RESUMO
OBJECTIVE: To assess compliance with the antibiotic prophylaxis protocol for patients who underwent renal surgery and its effect on the incidence of surgical wound infection. MATERIAL AND METHODS: We performed a prospective cohort study and assessed the overall compliance and each aspect of the antibiotic prophylaxis (start, administration route, antibiotic of choice, duration and dosage) and reported the compliance rates. The qualitative variables were compared with the chi-squared test, and the quantitative variables were compared with Student's t-test. We studied the effect of antibiotic prophylaxis compliance on the incidence of surgical wound infection in renal surgery, with the relative risk. RESULTS: The study included 266 patients, with an overall compliance rate of 90.6%. The major cause of noncompliance (3.8%) was the start of the prophylaxis, and the incidence rate of surgical wound infections was 3.4%. We found no relationship between antibiotic prophylaxis noncompliance and surgical wound infections (RR=0.26; 95%CI: 0.1-1.2; P>.05). Laparoscopic surgery had a lower incidence of surgical wound infections than open surgery (RR=0.10; 95%CI: 0.01-0.79). CONCLUSIONS: The antibiotic prophylaxis compliance was high. The incidence of surgical site infection was low, and there was no relationship between the incidence of surgical site infection and antibiotic prophylaxis compliance. The incidence of infection was lower in laparoscopic surgery.
