Examining the relationship between adherence and the number of cardiometabolic medications: Findings for patients with type 2 diabetes within a Tribal health care system

To our knowledge, this is the first study demonstrating the association between a higher number of cardiometabolic medications and better adherence in American Indian adults diagnosed with T2D whose medications were provided without cost to the patients. Medication cost is a well-known medication adherence barrier. Future studies should further examine factors associated with nonadherence in this population, such as younger age and fewer medications.
