Why the study?
Surgical site infections are a major public health problem worldwide that increase morbidity, mortality, and hospital stay, prompting this study to determine SSI incidence, bacteriological profiles, and resistance patterns in a tertiary care centre.
Gram negative bacilli, particularly Klebsiella pneumoniae, and MRSA are the predominant pathogens responsible for surgical site infections in this tertiary care setting, highlighting the need for targeted infection control and antibiotic prophylaxis.
May inform local SSI surveillance; leaves open whether pathogen-specific prophylaxis reduces incidence.
BACKGROUND postoperative surgical infections occurring in an operative site are termed Site Infections (SSIs). SSI is a common form of nosocomial infection and a common complication associated with surgery. They are responsible for cost, length of hospital stay, morbidity and mortality. Surgical site is a major public health problem worldwide. We wanted to determine the of SSI rates, bacteriological profile, and the resistant pattern in a tertiary centre. prospective study was conducted in a tertiary care centre in Bangalore in the of Microbiology over a period of 6 months. 180 patients with surgical infections were studied. Wound swabs and pus samples were collected and as per standard microbiological techniques. Antimicrobial testing was using Vitek 2K automated method. MRSA, ESBL types of resistance among isolates were detected and characterized as per CLSI guidelines. 1734 patients, 180 (10.3%) patients developed surgical site infections (SSI). SSIs were more frequent in the age group of 36 - 45 years. Males were likely to get SSIs. Diabetes mellitus was the commonest comorbid condition in SSI cases. Pre-operative waiting period beyond 7 days, not receiving antibiotics, dirty and contaminated surgeries were the other factors for SSIs. Gram negative bacilli were the predominant isolates SSIs. Klebsiella pneumoniae was the most frequent isolate followed by E. coli. (Methicillin Resistant Staphylococcus aureus) was the predominant isolate Gram positive bacteria. These strains demonstrated extensive antibiotic to the drugs tested. postoperative wound infections relies on adequate asepsis, efforts to the duration of surgery without compromising the patient’s safety and outcome. Implementation of an effective infection control programme judicious use of antibiotic prophylaxis reduces the incidence of SSIs in the .
