Racial and Ethnic Disparities in Medication Adherence Among Medicare Advantage Enrollees With Diabetes

This retrospective cohort study of MA enrollees with diabetes found racial and ethnic disparities in diabetes medication adherence. Disparities in adherence to insulin or SGLT2 inhibitors and/or GLP-1 RAs were partially mitigated by Medicaid and prescription drug subsidies but less so by plan-level factors. The findings suggest that additional insurance- and community-level strategies are needed to improve medication adherence among disadvantaged patients and communities.
