BackgroundThe objective of this study is to assess the possible association between intraoperative anesthesia team handovers and increased 90‐day major complications following HPB surgery.MethodsThis is a single‐center retrospective cohort study of patients who underwent HPB surgery. Anesthesiologist handover (AH) occurred when a complete transfer of care to a receiving anesthesiologist. total anesthesia team handovers (TH) occurred when both anesthesiologist and supervised provider transferred care. The primary outcome was 90‐day major complications, defined as an ACCORDION score of ≥ 3.ResultsNinety‐day major complications occurred in 35 (21.6%) of TH and 96 (21.9%) of AH patients. With adjustment of other covariates, no significant association was found between AH (OR, 1.358, 95% CI, 0.935–1.973, p = 0.1079) or TH (OR, 1.157, 95% CI, 0.706–1.894, p = 0.5633) and 90‐day major complications.ConclusionsIn a high‐volume HPB center, anesthesia team handovers were not associated with an increased risk of patients having a major complication within 90 days after HPB surgery.
