AN ANALYSIS OF SURGICAL SITE INFECTION IN CLEAN GENERAL SURGICAL OPERATIONS IN PO WARDS
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 94
Abstract
BACKGROUND Surgical site infections represent a significant burden in terms of patient morbidity and mortality and cost to health services around the world. 1 Surgical site infection (SSI) is a potentially preventable complication. Hence, an observational study was done to determine possible modifiable risk factors, incidence rates and clinical patterns of surgical site infections (SSI) in our institution. MATERIALS AND METHODS This is an observational study on 650 patients who underwent various clean General Surgical operations from 01/01/2008 to 30/09/2009, who were analysed from 1st post-operative day to the day of suture removal for SSI in the post-operative wards. Study standards such as pre-operative shower, preoperative antibiotics, operating room environment, operating time for a particular surgery, post-op wound care and other sterility techniques were set similar for all patients who underwent the surgeries. The statistical significance of the risk factors studied is done by X2 test and the strength of association is determined by Odds Ratio. RESULTS The incidence rate of SSI was 6.2%, which is close to the acceptable rate (1% - 5%) for clean surgeries. Diabetes, anaemia, obesity and duration of surgery have a statistically significant correlation with the development of surgical site infections with odds ratio of each being 19.20, 7.33, 4.75 and 3.14 respectively. Increase in number of risk factors probably further increases the chance of SSI. Staphylococcus aureus was the commonest organism isolated; 76.2% were due to Gram positive organisms and rest 23.8% due to Gram negative organisms. CONCLUSION The incidence rate of SSI was within the acceptable limit for all clean surgeries. The strength of association of risk factors studieddiabetes, anaemia, obesity and duration of surgery is well established with the development of SSI. Increase in number of risk factors further compounds the chance of SSI. Staphylococcus aureus was the commonest organism isolated.
