External Validation of the Ventral Hernia Risk Score for Prediction of Surgical Site Infections

摘要

Background: Previously, we reported that the Ventral Hernia Risk Score (VHRS) was more accurate in a Veterans Affairs (VA) population in predicting surgical site infection (SSI) after open ventral hernia repair (VHR) compared with other models such as the Ventral Hernia Working Group (VHWG) model. The VHRS was developed using single-center data and stratifies SSI risk into five groups based on concomitant hernia repair, skin flaps created, American Society of Anesthesiologists (ASA) score >= 3, body mass index >= 40 kg/m(2), and incision class 4. The purpose of this study was to validate the VHRS for other hospitals.
