Background: Surgical site infections (SSIs) are a significant cause of postoperative morbidity, prolonged hospital stay, and increased healthcare costs worldwide. Identifying incidence and risk factors in tertiary care settings helps improve preventive strategies.
Objective: To determine the incidence and risk factors associated with SSIs among patients undergoing surgery in a tertiary hospital.
Methods: This prospective observational study included 120 patients undergoing elective or emergency surgeries over a 12-month period. Demographic data, comorbidities, perioperative factors, and postoperative outcomes were recorded. SSI was defined according to CDC criteria. Risk factors were analyzed using univariate and multivariate logistic regression.
Results: The overall SSI incidence was 18.3% (22/120). Emergency surgeries (OR 3.2, 95% CI 1.2-8.5), diabetes mellitus (OR 2.8, 95% CI 1.1-7.2), prolonged operative duration >120 minutes (OR 4.1, 95% CI 1.5-11.2), and ASA score ≥3 (OR 3.5, 95% CI 1.3-9.4) were significant independent risk factors. Gram-negative bacteria, predominantly Escherichia coli and Klebsiella species, were the most common pathogens.
Conclusion: SSIs remain a notable complication in tertiary hospitals. Awareness of modifiable risk factors, proper perioperative management, and infection control protocols can significantly reduce SSI incidence.
