Incidence of surgical site infection in colon surgery according to RENAVE methodology: Prospective study 2017–2019

Abstract

BackgroundNavarra Hospital Complex has renovated its healthcare-associated infections surveillance and control methods meeting the requirements of the Spanish National Epidemiologic Surveillance Network. Surgical site infections are one of the most relevant adverse outcomes, being the colon surgery one of the mandatory monitored procedures. This system will ease, not only the yearly estimation of the hospital surgical infection rates, but also its comparison at national and European levels. Methods416 patients underwent surgery between 2017 and 2019. Clinical variables were gathered during the patient hospitalization and up to 30 days from surgery, stratifying the cases by their NHSN (National Health Safety Network) surgical infection risk index. A univariant descriptive analysis was performed and outcome indicators were estimated. ResultsThe cumulative incidence was 10.6%, with 44 cases. The rates were higher among the high-risk subgroups: 25.0% and 42.9%, respectively, for NSHN index categories 2 and 3. ConclusionsThe incidence was similar to the ones found in other studies carried out in analogous conditions. However, the methodologic variability makes it difficult to compare results.
