Routinely available perioperative variables and EHR-captured postoperative adverse-event indicators after adult abdominal surgery: A retrospective cohort study using MOVER EPIC

Background

Perioperative electronic health record (EHR) datasets are increasingly used to study postoperative morbidity, although database-recorded adverse-event indicators may not correspond to standardized complication endpoints. We characterized these indicators after adult abdominal surgery in MOVER EPIC and examined associations with routinely available perioperative variables.
