The Implementation of an Acute Pain Service for Patients Undergoing Open Ventral Hernia Repair with Mesh and Abdominal Wall Reconstruction

Introduction In this retrospective cohort single-institutional study, we report the outcomes of implementing a standardized protocol of multimodal pain management with thoracic epidural analgesia via the acute pain service (APS) for patients undergoing ventral hernia repair with mesh placement and abdominal wall reconstruction. Methods The primary outcome evaluated was postoperative 72-h opioid consumption, measured in intravenous morphine equivalents (MEQ). Secondary outcomes included hospital length of stay (LOS) among other outcomes. The two cohorts were the APS versus non-APS group, in which the former cohort had an APS providing epidural and multimodal analgesia and the latter utilized pain management per surgical team, which mostly consisted of opioid therapy. Using1:1 propensity-score-matched cohorts, Wilcoxon signed-rank test was used to calculate the differences in outcomes. A p
