In total of 1139 patients surgical procedures were performed in the selected ward during the study period, of which 19 dropped out from the study; of the remaining 1120 patients 82 (7.3%) patients developed surgical site infection. Incidence of surgical site infections was higher in emergency procedures (13.1%) as compared to elective procedures (2.9%). Incidence related to clean, clean contaminated, contaminated and dirty procedures was 1.5%, 2.5%, 6.5% and 21.5% respectively. Age, wound class, electivity of procedure and diabetes were identified as the main contributing factors towards the development of surgical site infections.
