Assessment of Surgical Site Infection in A Tertiary Care Set Up in Kolkata
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 12
Abstract
The common Health Care Associated Infection (HCAI) as per CDC updated 2007 is UTI (32%) followed by postoperative wound infections (22%), Nosocomial pneumonia (15%) and Nosocomial septicaemia (14%). Keeping these facts in mind, the present study aimed at the assessment of the surgical site infection in a tertiary care set up in eastern India. The study was conducted in the Department of Microbiology, in a tertiary care set up of Kolkata from January to December, 2016. The total number of elective and emergency surgeries done during the one-year period was 402 which included 373 elective (major) and rest, emergency cases. Twenty two cases were clinically suspected to be postoperative wound infection were studied as per standard microbiology guidelines. The commonest microorganism causing wound infection in the study was Staphylococcus aureus (11 out of 22 i.e., 50%) followed by Escherichia coli (6 out of 22 i.e., 27%). Pseudomonas aeruginosa (2 out of 22 i.e., 9%), Klebsiella pneumonia (2 out of 22 i.e., 9%)and Acinetobacter spp.(1 out of 22 i.e., 4.5%) were also isolated. No polymicrobial involvement was found. Amongst 11 isolated Staphylococcus, 6 were MRSA (Methicillin Resistant Staphylococcus aureus) (54.5%) and all the Staphylococcus isolates were sensitive to Vancomycin and Linezolid. All the Gram negative isolates were sensitive to polyene antibiotics. One Pseudomonas, one Klebsiella and the Acinetobacter isolates were carbapenemase producers. 8 out of 11 Staphylococcus isolates (72%), 4 out of 6 Escherichia coli isolates (66.7%), all Pseudomonas and Acinetobacter isolates were resistant to fluoroquinolones. 4 out of 11 Gram negative isolates were ESBL producers (36.3%)and 3 were Amp C beta lactamase producers (27.2%). Postoperative wound infection (surgical site infection) is an important aspect of Nosocomial infections which demands implementation of antibiotic stewardship and apt sterilization practices.
