1643-P: Prevalence of Diabetes Medication Regimens in PCORnet, the National Patient-Centered Clinical Research Network

Abstract

Background: Understanding the long-term cardiovascular safety of type 2 diabetes (T2D) medications is a high-priority research area. We used electronic medical record (EMR) data in the National Patient Centered Clinical Research Network (PCORnet) to characterize “real-world” use of T2D medications. Methods and Results: We identified a retrospective cohort of patients with T2D using a validated computable phenotype. We queried 4 unique PCORnet sites for data regarding T2D medication use in the 90 days before and after cohort entry. We described patient demographics, comorbidities, non-T2D medication use, and clinical variables in the 730 days prior to cohort entry. We identified 49,654 patients with T2D across the 4 sites (range: 2,276-20,322). Use of T2D medications, characterized by pharmacologic class, and selected characteristics are presented in Table. Among patients prescribed a single class of T2D medication, metformin was the most common (52.5%). Among patients prescribed multiple classes of T2D agents, the most common combination was metformin and sulfonylureas (49%). Conclusions: Across 4 PCORnet sites, metformin-based regimens were very prevalent, and approximately 10% of regimens included newer agents. PCORnet will be a valuable resource for future observational studies of T2D medications and long-term cardiovascular outcomes in “real-world” populations. Disclosure K.N.
