Background: Surgical site infections (SSI) are one of the most common hospital-acquired infections worldwide. SSI are known to increase morbidity, mortality, length of stay in hospital as well as the cost of treatment to the patients. The incidence varies from 1% to 20% among developed countries to as high as 40% in developing world. Aims: To find the incidence and risk factors, bacteriological profile, and antibiogram for SSI in General Surgery department of a tertiary care hospital in Western Rajasthan. Methods: Culture and sensitivity of wounds of all the clinically suspected cases of SSI were taken. Bacterial identification and antimicrobial susceptibility were performed according to standard CLSI guidelines. Statistical analysis was done using Microsoft Excel, SPSS 13 software. Results: Among total 609 patients, 102 were clinically suspected SSI and 88 were culture positive. Incidence of SSI was 14.45%. The most common organism was Staphylococcus aureus followed by Klebsiella pneumoniae. Most of the Gram-positive isolates were resistant to penicillin and cephalosporin antibiotics and were moderately susceptible to fluoroquinolones and aminoglycosides. Gram-negative isolates were resistant to beta-lactam and beta-lactam/beta-lactamase inhibitor combination also but were susceptible to fluoroquinolones, aminoglycosides, and carbapenems. Conclusion: High incidence rate of SSI in our setup emphasizes the need of quality surgical care which takes into consideration all the three important factors, i.e. host, environmental, and microorganism characteristics before doing any surgery. Increasing resistance to commonly used antibiotics warrants the judicious use of antibiotics and establishment of antibiotic policy in the hospital.
