Objective: To identify factors responsible for the variation in real hospital costs and length of stay for patients with diabetes undergoing coronary angioplasty or coronary bypass surgery. Study design: Retrospective study of patients with diabetes and coronary artery disease treated at a single hospital. Patients and methods: The study population included 1809 patients with diabetes and multivessel (2-vessel or 3-vessel) coronary artery disease who underwent an initial coronary angioplasty or coronary bypass surgery between 1988 and 1996. After accounting for the extent and severity of the patient's coronary artery disease, a sequential model was used to assess if diabetic characteristics were independently associated with higher hospital resource utilization during revascularization. Results: Multivariate regression results indicated that for patients with diabetes who underwent coronary angioplasty, a baseline creatinine level of ≥2.0 mg/dL was associated with significantly higher hospital costs and longer length of stay. For patients with diabetes who underwent a coronary bypass surgery only, a baseline creatinine level of ≥2.5 mg/dL was associated with higher hospital costs and longer hospital length of stay.
