Prevalence of surgical site infections in a tertiary care teaching hospital in Goa, India: a cross-sectional study

Abstract

Background: Surgical site infections (SSIs) are a major category of healthcare-associated infections (HAIs), particularly in surgical settings. They lead to extended hospital stays, increased morbidity, and financial burden. The study was conducted in the surgical wards of Goa medical college, a tertiary care hospital, to assess the prevalence of SSIs and identify the key bacterial pathogens and associated risk factors. Methods: A cross-sectional, prospective study design was employed, involving 378 patients aged over 18 years admitted for surgical procedures. Data collection included daily follow-up for signs of infection, identification of bacterial pathogens, and analysis of potential risk factors such as age, type of surgery, duration of postoperative drain, length of hospital stays, and wound classification. Statistical analyses were conducted using SPSS software, with significance set at p<0.05. Results: The study identified an SSI prevalence of 12.69% among the participants, with Pseudomonas being the most common causative agent. Significant risk factors included extended postoperative drain duration, longer hospital stays, emergency surgical procedures, and surgeries involving contaminated or clean-contaminated wounds. Patients with prolonged postoperative drains had a markedly higher incidence of SSIs (63.63%). Conclusions: The findings reveal a considerable burden of SSIs in the studied setting, with high infection rates in patients undergoing prolonged drain usage, emergency surgeries, and surgeries on contaminated wounds. Strengthening infection prevention measures, particularly in high-risk cases, and enforcing strict adherence to hygiene and sterilization practices are critical. Enhanced infection surveillance programs and targeted interventions could help reduce SSI rates, improve patient outcomes, and minimize healthcare costs.
