Cost-related non-adherence to asthma medications remains a challenge

Study design: Analyzing data from the National Health Interview Survey (2011-2022), researchers evaluated trends in cost-related non-adherence (CRN) to asthma medications among U.S. adults. The study included 30,793 adults with asthma, representing 8.1% (19.38 million) of the U.S. population.

Results: A declining trend in CRN over the years was observed, yet approximately one in six adults with asthma still reported non-adherence due to cost. Factors associated with CRN included demographics and comorbidities. Patients with CRN had a higher risk of asthma attacks (adjusted OR, 1.95) and ED visits (adjusted OR, 1.63) compared with those who adhered to their medication regimen.

Impact on clinical practice: Despite improvements, CRN to asthma medications remains a significant issue. Recognizing financial barriers and considering strategies to mitigate these challenges can improve asthma control and reduce adverse outcomes.
