Introduction: Surgical site infections are the third most common hospital associated infection, accounting for 14-16 per cent of all infections in hospitalized patients. External risk factors fo SSI include the type and duration of operation, surgeon’s skill, the quality of preoperative skin preparation, adequacy and timing of antimicrobial prophylaxis, insertion of foreign material or implants, inadequate sterilisation of surgical instruments. Materials and Methods: This prospective study was conducted in Surgery department of tertiary care hospital of Gujarat among 140 patients underwent non-traumatic abdominal surgeries. The records was scrutinized such patients files, operating theatre records, anaesthetic chart records, laboratory reports, theatre master record book. All factors related to SSI were recorded in the data collection sheet. Results: Surgical site infection rate was 17.1%. SSI rate was more in of emergency surgeries (29.3 %,) as compared to elective surgeries (8.5%). The rate of SSIs increased with increase in time of surgery as 4.6% in less than 1 hour and 60.0% more than 2 hours respectively. SSI rate was high in dirty wounds (32.6 %) and contaminated wounds (27.3 %). The postoperative hospital stay was very less for patients without SSI (4.21 ± 2.32 days) as compared to patients with SSI (13.64 ± 5.43 days, < 0.05).
