Abstract

This is a historic cohort study on surgical site infection occurred in 3,543 operations in orthopaedic patients. The surgical interventions were registered in the database of the Nosocomial Infection Control System of a Public General Hospital in Minas Gerais. Its objectives were to determine the incidence rate of surgery site infection, to verify the association between surgical site infection and some risk factors, to identify the prevalent microorganisms as well as the time for the infection's symptoms manifestation. The incidence rate of surgical site infection was 1.8%. The potential surgery wound infection, the patient's clinical condition (ASA), the surgery duration and the type of procedure were the variables statistically associated with SSI. After surgery the average time to the manifestation of infection was 96 days. The prevalent microorganism was Staphylococcus aureus
