Surveillance for surgical site infections developed during hospital stay & after discharge: A multicentric study

Background & objectives: Surgical site infections (SSIs) are among the most prevalent healthcare-associated infections (HCAIs). They cause significant morbidity, leading to excess health expenditures and increased length of hospital stay. Despite a high population burden, data on post-discharge SSIs is lacking from low-and middle-income countries (LMICs). There is no existing surveillance system of SSIs in India that covers the post-discharge period. Therefore, we proposed a multicentric analysis to estimate the proportion and identify the risk factors associated with SSIs occurring during hospital stay and after discharge. Methods: SSI Surveillance was conducted in three hospitals in different parts of India according to the Centers for Disease Control and Prevention (CDC) guidelines (30 days-6 months). An indigenous database was developed for data entry and analysis. Logistic regression analysis was performed to test for an association between SSI and potential risk factors. Results: A total of 161 out of 3090 patients acquired SSI, resulting in a 5.2 per cent SSI incidence. Debridement surgery, which was carried out with either an amputation, open reduction internal fixation surgery (ORIF), or closed reduction internal fixation (CRIF) surgery, had the highest SSI rate (54.2%). Clean, polluted wound class and surgeries lasting longer than 120 minutes were substantially linked to an increased risk of SSI. Interpretation & conclusions: Post-discharge surveillance helped with the detection of 66 per cent of SSI cases. Combination surgeries were seen to increase the risk of SSIs in patients.
