Facility-Level Variation in Cardiac Stress Test Use Among Patients With Diabetes: Findings From the Veterans Affairs National Database

摘要

Cardiac stress testing in patients with diabetes mellitus (DM) is a topic of much debate (1,2). The clinical heterogeneity and varied interpretation of atypical symptoms in this population may lead to significant variation in cardiac stress testing with downstream implications in health care expenditure. We evaluated facility-level variation in cardiac stress test use among patients with DM across the Veterans Affairs (VA) health care system.
