421-P: Documentation of Heart Failure in Outpatients with Type 2 Diabetes and Evidence of Volume Overload: A Report from the Diabetes Collaborative Registry (DCR)

Background: Heart failure (HF) is one of the most common and morbid complications of T2D. Prompt recognition of early signs of HF may avert HF hospitalization and may also impact T2D meds (e.g., TZDs or possibly SGLT2i). We determined the rate and factors associated with HF diagnosis in T2D patients with evidence of volume overload requiring loop diuretics. Methods: DCR is a U.S. registry of outpatient T2D patients from 3074 cardiology, endocrinology, and primary care providers. Among T2D patients receiving loop diuretics, we examined the rate of documentation of HF. We excluded patients with chronic liver disease, as they may have a non-HF indication for loop diuretics. Results: Among 931,361 adults with T2D, 215,957 (23%) were on a loop diuretic of whom 110,809 (51%) had documentation of HF. Patients seen by cardiologists and PCPs were more likely have HF documented vs. endocrinologists (52% and 50% vs. 22%; p
