The Association of Intraoperative Anesthesia Handovers of Anesthesia Care With Adverse Postoperative Outcomes: A Retrospective Multicentric Cohort Study
Main finding · HLOSResult — go to the resultAdjusted model estimate (MEadj) 1.02 95% CI 1.02–1.03Authors' conclusion
Intraoperative handover of anesthesia care is associated with a small but measurable increase in HLOS and increased 30-day unplanned readmission, particularly in major surgical cases.
