INTRODUCTION: Surgical site infection (SSI) is third most commonly reported Nosocomial infection accounting for 5 to 34% globally. It is a major cause of postoperative morbidity and is the commonest and most troublesome complication of wound healing. There are many factors that influence healing of surgical wound and determine the potential for infection. It includes patients related or procedure related variables that affects a patient’s risk of developing SSI. Some of the risk factors are increasing age, smoking, tobacco chewing, high glycaemic index, nutritional status, BMI, duration of pre operative hospital stay and sterilization of surgical field etc. Some of this factors are non modifiable for example age but others can be improved to increase a positive outcome. This study was conducted to assess the relationship between one of the risk factor that is basal metabolic rate with surgical site infection. OBECTIVES: To assess the rate and relation of Surgical Site Infection (SSI) with Body Mass Index (BMI) . MATERIAL and Methods: It is a prospective observational study conducted at Ajmal Khan Tibbiya College in collaboration with Department of microbiology Jawahar Lal Nehru AMU, on 200 patients who underwent elective abdominal surgeries as per inclusion and exclusion criteria. Patients were stratified into 4 categories according to BMI : Class I(<18.5), Class II (18.5-24.9),Class III (25-29.9)and Class IV(>30). SSI assessed as per criteria established by CDC and WHO and then relation between BMI and SSI was established.The chi square has been applied and the results were analyzed statistically RESULTS: Total 200 different elective surgeries were analysed, out of which maximum patients with SSI were found in category III. Among 200 patients 26 patients were lie in category III.A trend of increasing risk of SSI when BMI increased from normal to obese was observed. CONCLUSION: This study demonstrated that there is increase in SSI with increase BMI. Thus we concluded that by reducing weight we can prevent surgical site infection which leads to decrease hospital stay and ultimately it is more cost effective.
