AN EPIDEMIOLOGICAL RETROSPECTIVE ANALYSIS OF THE MICROBIAL FLORA AMONG INFECTED SURGICAL WOUND CASES IN LOCAL SECONDARY & TERTIARY CARE HOSPITALS.

Abstract

Introduction : According to the CDC, one-to-three cases out of 100 surgeries get infected. There is considerable variation in each class according to the type of surgery being performed. The incidence of infection varies from surgeon to surgeon, from hospital to hospital, from one surgical procedure to another and, most importantly, from one patient to another. The aim of this study was to identify the most common microorganism documented in post-operative wound sepsis in surgery wards of local tertiary hospitals situated in Chhattisgarh. Methods: This Retrospective & Analytical study involved Prior Consent from Hospital Authorities / Medical Superintendents of the Randomly selected Private Tertiary care hospitals to see the records of the patients from Medical Records Department ( MRD) The study included 100 randomly selected case sheets / records of the patients suffering from SSIs in the various surgical wards in local tertiary care centres . Patients of both sex, age > 14 years, who had surgical wound pus discharge, with serous or seropurulent discharge and with signs of sepsis present concurrently were included. Results : Out of the 100 selected case sheets / records of patient’s samples processed, In 91% of records it was found that it yielded aerobic bacterial growth . Monomicrobial growth was seen in 92 samples while 8 samples showed polymicrobial growth. The mean age of the patients was 45.7 years (range 14 to 79 years) and the peak incidence of SSI was observed in age group > 50 years (55%). Among the 100 records / cases, bacterial isolates, S. aureus (52%) and E. coli (24.%) were the commonest organisms. Conclusion: . The information obtained from this study allows a better understanding of the microbial etiology of SSIs in local hospitals which may have epidemiological and therapeutic implications. Using the results of this study, an initiative for establishing improved hospital antimicrobial policy and antimicrobial prescribing guidelines can be undertaken.
