Chung GC, et al. - By performing this cross-sectional examination of the 2017 National Health Interview Survey (NHIS) in the United States, researchers estimated the rate of as well as risk factors related to cost-related medication nonadherence among older adults. The participants aged 65 years or older (n = 5,701 unweighted) in the 2017 wave of the NHIS. In 2017, cost-related medication nonadherence was reported by 408 (6.8%) of 5901 older adults, who represent 2.7 million older adults nationally. They found that 44.2% of those with cost-related medication nonadherence asked their physician for lower-cost medications. Alternative therapies were adapted by 11.5%, and 5.3% purchased prescription drugs outside the United States to save money. Younger age, female gender, lower socioeconomic levels (eg, low income and uninsured), mental distress, functional limitations, multimorbidities, and obesity were all identified as correlates independently related to a higher probability of cost-related medication nonadherence. Findings revealed an increasingly common incidence of cost-related medication nonadherence among older adults. Many risk factors identified in this study were potentially modifiable. In order to attenuate this issue in older adults, there may be a requirement of interventions, such as medication therapy management.
