We examined the incidence of infection with methicillin-resistant Staphylococcus aureus (MRSA) in patients admitted to the Leicester Royal Infirmary Trauma Unit between January 2004 and June 2006. The influence of MRSA status at the time of their admission was examined, together with age, gender and diagnosis, using multi-variant analysis. Of 2473 patients, 79 (3.2%) were MRSA carriers at the time of admission and 2394 (96.8%) were MRSA-negative. Those carrying MRSA at the time of admission were more likely to develop surgical site infection with MRSA (7 of 79 patients, 8.8%) than non-MRSA carriers (54 of 2394 patients, 2.2%, p < 0.001). Further analysis showed that hip fracture and increasing age were also risk factors with a linear increase in relative risk of 1.8% per year. MRSA carriage at admission, age and the pathology are all associated with an increased rate of developing MRSA wound infection. Identification of such risk factors at admission helps to target health-care resources, such the use of glycopeptide antibiotics at induction and the 'building-in' of increased vigilance for wound infection pre-operatively.

Background: This study aims at determining the risk factors and incidence of surgical site infections. Methods: The material for the present study was obtained from patient’s undergone surgery in Department of General Surgery, SPMC and PBM Hospital, Bikaner, Rajasthan from 1st Jan 2019 to 31th December, 2019. Surgical site were considered to be infected according to the definition by NNIS. The wounds were classified according to the wound contamination class system proposed by U.S. National Research Council. Results: A study of 400 operated cases was carried out of which 39 were diagnosed to be having surgical site infection as per the CDC criteria. Thus the incidence of SSI in this study is 9.75%. Conclusion: Incidence of surgical site infection was more in emergency surgery case as compare to elective. Keywords: SSI, Emergency, Elective
