Abstract
Objectives. This study estimated national prevalence rates of medication noncompliance due to cost and resulting health problems among adults with disabilities. Methods. Analyses involved 25 805 respondents to the Disability Follow-Back Survey, a supplement to the 1994 and 1995 National Health Interview Surveys. Results. Findings showed that about 1.3 million adults with disabilities did not take their medications as prescribed because of cost, and more than half reported health problems as a result. Severe disability, poor health, low income, lack of insurance, and a high number of prescriptions increased the odds of being noncompliant as a result of cost. Conclusions. Prescription noncompliance due to cost is a serious problem for many adults with chronic disease or disability. Most would not be helped by any of the current proposals to expand Medicare drug coverage.
