Abstract
OBJECTIVE: To assess changes in antidiabetes medication class prescriptions over time among patients with diabetic kidney disease (DKD), characteristics of patients prescribed these medications, and prescribers' specialty. RESEARCH DESIGN AND METHODS: We conducted a cohort study design using insurance claims data between 2013 and the first quarter of 2020 (2020Q1). Included are adult patients with DKD who initiated a new antidiabetes medication between 2013 and 2020Q1 (N = 160,489 patients). The primary outcome is the yearly and quarterly percent of medication initiation for each antidiabetes medication class over all antidiabetes medication initiations. RESULTS: For patients with DKD, sodium-glucose cotransporter 2 inhibitor (SGLT2i) and glucago-like peptide 1 receptor agonist (GLP-1RA) initiations steadily increased between 2013 and 2020Q1. Internists and endocrinologists were the most frequent prescriber specialties. Patients <65 years of age had a larger percentage of all initiations that were SGLT2i or GLP-1RA, 16% and 23%, respectively, in 2019, and patients >75 years of age had a smaller percentage of all initiations that were SGLT2i or GLP-1RA, 11% and 13%, in 2019. CONCLUSIONS: For patients with DKD, SGLT2i and GLP-1RA prescriptions have increased over time, likely reflecting evolving prescribing patterns in response to the results of recent clinical trials and new clinical guidelines.
