Objectives: Surgical site infection (SSI) is a major nosocomial infection in surgical patients. Despite the advances in techniques and knowledge to prevent infection, SSI remains a significant source of postoperative morbidity and mortality. The aim of this study was to assess the incidence and the risk factors of SSI for patients who underwent colorectal surgery, to analyze the prolonged hospital stay and to provide basic date for SSI surveillance.
Methods: We performed a retrospective review of 174 patients who underwent colorectal surgery between 2011 and 2012 in
National Health Insurance Corporation Ilsan Hospital. We evaluated the association of SSI with patient factors, comorbidities, intraoperative factors and prophylactic antibiotics. The impact of SSI on the postoperative hospital stay was evaluated.
Results: The overall incidence of SSI was 7.5%. The duration of the operation (p=0.019) and sex (p=0.018) had a statistically significant association with an increased risk of SSI. Age, American Society of Anesthesiology score, body mass index, diabetes were not associated with SSI. Prophylactic antibiotics were administrated in one hour before incision in 79.3% patients, and not associated with SSI. Postoperative hospital stays were significantly increase in patients with SSI (p<0.01).
Conclusion: The duration of the operation and sex seem to affect SSI following colorectal surgery. SSI results in an increased length of hospital stay. This result suggests that hospitals need to create strategies to reduce SSI through effective infection surveillance and prospective study with more patients will be necessary for risk factors of SSI.
