  • Background: Surgical site infection (SSI) is one of the most common healthcare-associated infections (HAIs). SSI following hepatobiliary surgery is not well described. This study aims to describe and assess factors associated with SSI following hepatobiliary surgery in Japan, using a Japanese national database for HAIs.

    Methods: Data on hepatobiliary surgeries performed between 2012 and 2014 were extracted from a national surveillance system for healthcare-associated infections, Japan Nosocomial Infections Surveillance (JANIS). Hepatobiliary surgery was divided into three types; pancreaticoduodenectomy (BILI-PD), liver resection (BILI-L) and others (BILI-O). Factors associated with SSI following three types of hepatobiliary surgery were assessed using multivariate logistic regression analysis.

    Results: The overall incidence of SSI following hepatobiliary surgery was 15.6% (2,873/18,398). Incidence of SSI following BILI-PD was 28.0%. It was significantly higher than that following BILI-L and BILI-O (8.8% and 15.5%, respectively). Among the four traditional risk factors included in the National Nosocomial Infections Surveillance (NNIS) modified risk index, American Society of Anesthesiologists (ASA) score were insignificant in predicting SSI in the final model for all of three types of surgery. Use of laparoscope was a protective risk factor in BILI-L and BILI-O, but not in BILI-PD. Additional risk factors were identified, including age in all types of hepatobiliary surgery and male gender in BILI-PD and BILI-O.

    Conclusion: Incidence of SSI and risk factors associated with SSI were significantly different among three types of hepatobiliary surgery. In order to accurately compare hospital performance regarding SSI following hepatobiliary surgery, dividing the operative procedure category in the surveillance system into three types is needed.
