777-P: Predictors of Selection of a GLP1RA vs. SGLT2i in People with Type 2 Diabetes and Atherosclerotic Cardiovascular Disease

Introduction: In people with T2D and preexisting ASCVD, either SGLT2i or GLP1RA are indicated by treatment guidelines to reduce MACE. We evaluated predictors of prescription of SGLT2i vs GLP1RA in a population eligible for either. Methods: An electronic health record (EHR) based registry was created to identify people with T2D and ASCVD who were indicated either a GLP1RA or SGLT2i for cardiorenal protection within a large, academic health system. Data pertaining to demographics, lab and imaging results, ICD9/10 diagnoses, prescriptions, provider and clinic characteristics were extracted. Eligible encounters occurred in a primary care, endocrinology, cardiology, or nephrology clinic between January 1, 2019 and August 23, 2023. For each eligible encounter where a drug was prescribed, the first treatment type (GLP1RA or SGLT2i) was determined based on medication history. We estimated a logistic regression using stepwise variable selection to identify a best-predicting model and forced the variables of age, sex, and race into the model. Results: A total of 315 patients with T2D and ASCVD were eligible for either treatment and were prescribed one of these medications: 142 were prescribed a GLP1RA and 173 were prescribed SGLT2i. Lower BMI was associated with use of SGLT2i (OR = 0.91, 95% CI 0.87-0.96), as was being an established patient (OR 2.32, 95% CI 1.14-4.72). Compared to treatment in a primary care setting, treatment in a cardiology clinic was strongly associated with prescription of SGLT2i (OR = 7.77, 95% CI 3.18-19.04), whereas treatment in endocrinology clinic was strongly associated with prescription of a GLP1RA (OR = 0.35, 95% CI 0.18-0.68). Area under the receiver operating characteristic curve for the model was 0.82. Conclusion: In a real-world dataset from a large academic center, the selection of guideline directed therapy for patients with T2D and ASCVD was strongly determined by the provider’s specialty, highlighting an important opportunity for education.
