Background: While many patients are admitted to hospital for treatment of infections, some acquire infection during their stay in the hospital. These infections are called as nosocomial infections. Surgical site infection or post operative wound infection is one of them. It is defined as infection of previously sterile tissue incised to gain exposure for operating deeper spaces operatively exposed or organs manipulated by a surgeon. It is one of the feared complications of surgery as it increases morbidity as well as cost of medical care. Aims and Objectives: Study was conducted to find out incidence of surgical site infection rate in surgical ward, evaluate various factors contributing to infection and to identify causative pathogens and their antibiogram patterns. Material and Methods: All clean and clean contaminated operative cases admitted in surgery ward in study period of 18 months were included. Preoperative, operative and postoperative management protocols of the cases were recorded in detail. Results: A total of 1082 operated cases were studied among which 59 infected cases were found. Surgical Site Infection (SSI) rate was 5.45%. E. coli and Staphylococcus aureus were the commonest pathogen isolated from the infected wound. 50 % were Methicillin Resistant Staphylococcus Aureus (MRSA) among them and 50% of rd Enterobacteriaceae group were resistant to 3 generation Cephalosporins. Conclusion: Surgical site infection rate of a hospital can be reduced easily by following proper pre-operative protocol for the patients. Those patients with surgical site infection can be treated effectively by following the antibiotic policy as provided by the Department of Microbiology.
