Postoperative dysglycemia in elective non-diabetic surgical patients: a prospective observational study.

Purpose: Elevated glycosylated hemoglobin (HbA1c) is often found in surgical patients with no history of diabetes. The purpose of this prospective observational study was to determine if elevated preoperative HbA1c is associated with postoperative hyperglycemia in non-diabetic surgical patients and to identify predictors of elevated HbA1c.

Methods: This study included 257 non-diabetic adults scheduled for inpatient surgery.
