Abstract
Context: Surgical Site Infections (SSI) has been responsible for the increasing cost, morbidity and mortality related to surgical operations. They continue to be a major problem even in hospitals with most modern facilities and standard protocols of preoperative preparation and antibiotic prophylaxis. Aim: The aim of this study to identify the aerobic bacteriological profile of Surgical Site Infections and its antibiogram, with special reference to Methicillin and Vancomycin resistance patterns of Staphylococcus aureus and Enterococci in this area. Settings and Design: This is a prospective study carried out in the Department of Microbiology for one and half year at Siddhartha Medical College/Government General Hospital, Vijayawada, Andhra Pradesh, India. Methods: Specimens were collected from those post operative wounds which were showing signs/symptoms of an infection during the stay of the patient’s in the hospital and also during their follow up visits to the outpatient department after their discharge from the hospital according to CDC guidelines. All the specimens collected were transported immediately to the laboratory for further processing according to standard protocols. Results: The prevalence of SSI is 8.94% (136 out of 1520 surgeries). Out of 136 clinically diagnosed SSIs, 113 organisms isolated. Out of 113 organisms, Staphylococcus aureus (28.31%) was the most predominant organism followed by Pseudomonas aeruginosa (17.69%). Among 32 strains of Staphylococcus aureus, 11(34.3%) MRSA and 1(3.12%) strain of VISA were detected. Conclusion: An effective national and state level antibiotic policy and draft guidelines should be introduced to preserve the effectiveness of antibiotics and for better patient management.
