OBJECTIVE To investigate whether diabetes affects perioperative complications or mortality and to gauge its impact on medical expenditures for noncardiac surgeries. RESEARCH DESIGN AND METHODSdWith the use of reimbursement claims from the Taiwan National Health Insurance system, we performed a population-based cohort study of patients with and without diabetes undergoing noncardiac surgeries. Outcomes of postoperative complications, mortality, hospital stay, and medical expenditures were compared between patients with and without diabetes. RESULTSdDiabetes increased 30-day postoperative mortality (odds ratio 1.84 [95%CI 1.46- 2.32]), particularly among patients with type 1 diabetes or uncontrolled diabetes and patients with preoperative diabetes-related comorbidities, such as eye involvement, peripheral circulatory disorders, ketoacidosis, renal manifestations, and coma. Compared with nondiabetic control patients, coexisting medical conditions, such as renal dialysis (5.17 [3.68-7.28]), liver cirrhosis (3.59 [2.19-5.88]), stroke (2.87 [1.95-4.22]), mental disorders (2.35 [1.71-3.24]), ischemic heart disease (2.08 [1.45-2.99]), chronic obstructive pulmonary disease (1.96 [1.29- 2.97]), and hyperlipidemia (1.94 [1.01-3.76]) were associated with mortality for patients with diabetes undergoing noncardiac surgery. Patients with diabetes faced a higher risk of postoperative acute renal failure (3.59 [2.88-4.48]) and acute myocardial infarction (3.65 [2.43-5.49]). Furthermore, diabetes was associated with prolonged hospital stay (2.30 [2.16-2.44]) and increased medical expenditures (1.32 [1.25-1.40]). CONCLUSIONSdDiabetes increases postoperative 30-day mortality, complications, and medical expenditures in patients undergoing in-hospital noncardiac surgeries.
