Cost-related medication nonadherence in adults with hypertension in the USA: implications for healthcare quality.

This study investigates cost-related medication non-adherence (CRN) among U.S. adults with hypertension, comparing those aged 18–64 years to seniors aged 65 and older, using data from the National Health Interview Survey (2019–2022). Findings indicate that younger adults, particularly uninsured individuals and women aged 18–64, are more likely to experience CRN than seniors, although seniors with certain insurance types, high cholesterol, or who currently smoke also face increased CRN risk. The study highlights that financial hardship, insurance status, comorbidities, and smoking are significant factors associated with CRN. To address these challenges, the authors recommend multi-faceted strategies including prescribing generic medications, connecting patients to assistance programs, and policy reforms aimed at reducing out-of-pocket costs to improve medication adherence and health outcomes in hypertensive populations.
