Background : Despite advances in operative techniques, better understanding of pathogenesis of wound infection, postoperative surgical site infections continue to be a major source of morbidity and mortality for patient undergoing operative procedures. The patterns of infection in surgical pa-tients varied among hospitals due to characteristics of the patients and type of operation performed. To make the infection surveillance and control programs effective, it is essential to understand the epidemiology of surgical infection in individual hospital.
Objectives :
1. To document the rates of surgical site infections stratified by risk
2. To identify the common causative pathogens
3. To identified the risk factors for surgical site infection
Material & Methods : A prospective study was employed and included 4,437 major opera- tions performed in 4,193 patients admitted to Songklanagarind Hospital. The period of the study was between September 1998 and March 2000. The hospital which the study was conducted is the 650- bed university hospital serving as medical school and tertiary care hospital. The study included the patients of the department of general surgery, neurosurgery, plastic surgery, urosurgery, pediatric surgery, and orthopedic surgery. Pertinent data were collected by two infection control nurses. Diag-nosis of hospital acquired infection were done by using CDC criteria.
Results : There were 506 hospital acquired infections recorded including 192 surgical site infections. The most common pathogen responsible for surgical site infection was Staphylococcus aureus. The independent risk factors for surgical site infection were :- duration of operation, ASA class, and degree of wound contamination.
