Abstract

Backround - surgical site infections (SSIs) are associated with increased morbidity and mortality as they can cause delay in recovery, increase length of stay, increase health care costs .This study was conducted to find out the prevalence of surgical site infection among various emergency and elective post surgical cases at a Medical College. Methodology - The study was conducted in the Department of Microbiology, Medical College, Calicut for a period of one year from July 2007 to June 2008. The total number of surgeries done during the one year period in three surgical units were 1902. One hundred and two cases of clinically suspected postoperative wound infection from the above cases was studied in detail. The study included 27 ‘clean’, 32 ‘clean-contaminated’ , 13 ‘contaminated’ and 30 ‘dirty’ cases. Two swabs were collected from each site. One swab was used for direct smear examination after Gram staining and second swab was subjected to culture and antibiotic sensitivity testing by standard microbiological techniques. Results - The incidence of postoperative wound infection was 5.36%. Among one hundred and two clinically suspected cases studied, bacteriologically proven surgical site infection was identified in thirty six patients. The prevalence of infection being 35% (36/102).Lowest infection rate was seen in clean(18.5%) surgery followed by clean-contaminated(37.5%), contaminated(38.5%) and dirty surgeries(47%). MRSA (Methicillin resistant Staphylococcus aureus) and multidrug resistant gram negative bacilli were predominant isolate. Conclusion -. The prevalence of infection being 35% ).Lowest infection rate was seen in clean surgery(18.5%) followed by clean-contaminated(27.5%), contaminated(37.5%) and dirty surgeries(47%). MRSA (Methicillin resistant Staphylococcus aureus) and multidrug resistant gram negative bacilli were predominant isolate.
