Background

Surgical Site Infections (SSIs) remain among the most common healthcare-associated infections worldwide. SSIs contribute significantly to postoperative morbidity, mortality, prolonged hospital stays, increased healthcare costs, and reduced patient quality of life. Understanding the risk factors associated with SSIs and implementing effective prevention strategies are essential for improving surgical outcomes.

Objective

To identify risk factors associated with surgical site infections and evaluate preventive measures that reduce SSI incidence among surgical patients.

Methods

A prospective observational study was conducted among 600 patients undergoing elective and emergency surgical procedures at tertiary healthcare institutions. Patient demographics, comorbidities, surgical characteristics, perioperative practices, and postoperative outcomes were recorded. Surgical site infections were diagnosed according to standardized clinical and microbiological criteria. Statistical analyses included descriptive statistics, chi-square tests, and multivariate logistic regression.

Results

The overall SSI incidence was 9.5%. Diabetes mellitus, obesity, prolonged operative duration, emergency surgery, smoking, and inappropriate antibiotic prophylaxis were identified as significant risk factors (p < 0.05). Adherence to infection prevention bundles significantly reduced SSI occurrence. The most commonly isolated organisms were Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa.

Conclusion

Surgical site infections remain a substantial postoperative complication. Comprehensive infection prevention strategies including proper antibiotic prophylaxis, perioperative glycemic control, surgical asepsis, and adherence to evidence-based protocols can significantly reduce SSI rates and improve patient outcomes.
