Key PointsQuestionAre levels of preoperative hemoglobin A1c or early postoperative glucose more useful at predicting postoperative complications and readmission following gastrointestinal surgery? FindingsThis retrospective observational cohort study of 23 094 operations at 117 Veterans Affairs medical centers found that peak postoperative glucose levels of less than 250 mg/dL were significantly associated with increased 30-day readmissions. By contrast, preoperative hemoglobin A1c of more than 6.5% was significantly associated with decreased 30-day readmissions. MeaningIncreased glycemic monitoring and the early treatment of hyperglycemia to maintain peak blood glucose levels of less than 250 mg/dL during the early postoperative period may minimize a patient’s risk of developing complications and being readmitted after undergoing gastrointestinal surgery.
