Sodium-glucose co-transport protein-2 inhibitors (SGLT2is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) have been shown to reduce cardiovascular events in high-risk patients with type 2 diabetes mellitus (T2DM). We examined real-world use of these agents at a US academic medical center in the state of Mississippi. Prescriptions, provider specialty, and insurance status of users of SGLT2is and GLP-1RAs in patients with T2DM, and T2DM and cardiovascular disease (CVD) seen from 1 January 2013 to 30 June 2019 were obtained by electronic health records review. We identified 21,173 patients with T2DM and CVD. Overall, 306 (1.4%) and 349 (1.6%) patients received a SGLT2i and GLP-1RA, respectively. After the US Food and Drug Administration (FDA) expanded empagliflozin and liraglutide indications, a mean difference of 19.2 and 12.7 greater quarterly new prescriptions was noted, while no such rise in canagliflozin was observed. Primary care physicians (PCP's) accounted for 53.4% SGLT2i prescriptions, endocrinology for 30.3%, and cardiology for 6.0%. PCP's accounted for 45.1% GLP-1RA prescriptions, endocrinology for 45.0%, and cardiology for 1.4%. Prescription patterns did not largely differ by patient insurance status. In conclusion, prescription of evidence-based therapies to improve CVD outcomes in high-risk patients with T2DM remains very low after several years of evidence generation. Low uptake was evident across insurance types. Modest increases in use were observed after regulatory expansions in labeling, however cardiologists rarely engaged in prescription, underscoring the need for widespread implementation strategies across healthcare systems.
