A STUDY ON SURGICAL SITE INFECTION SURVEILLANCE

Abstract

We started surgical site infection (SSI) surveillance from December 2003, and studied risk factors of SSI. A total of 1085 patients who had undergone surgery in our hospital were enrolled in the study. Operative emergency, wound contamination, preoperative condition (ASA score and nutrition), operation time, blood loss, and body mass index (BMI) were analyzed. The factors that caused significantly frequent SSI were emergency operation, wound contamination, high ASA scores, low nutrition, operation time, and blood loss. By multivariate studies, emergency operation, wound contamination, ASA score, and operation time influenced SSI significantly. We surveyed 16 patients who were treated for perforated appendicitis and studied the relation between antibiotic sensitivity for cultured bacterium and SSI. The cases of negative antibiotic sensitivity caused a significantly high rate of SSI. In our study, emergency operation, wound contamination, ASA score and operation time were found to be risk factors of SSI, and in contaminated operations, antibiotic sensitivity affected the incidence of SSI.
