OBJECTIVES: To examine the extent to which strategies adopted by homebound older adults to reduce or restrict out-of-pocket prescription medication cost persist over time. METHODS: Multivariate logistic regression models were employed to examine the magnitude and correlates – sample characteristics, drug coverage, consistent use of behaviors to cope with out-of-pocket drug expense, and increased difficulty paying for medications – for continued use of strategies to reduce or restrict medication cost in 177 randomly recruited homebound older adults who completed two in-home assessments (baseline and 1-year follow-up). RESULTS: At 1-year assessment, 19% of participants used ≥1 behavior that restricted medication use (11% at both assessments); 24% (18% at both assessments) used ≥1 strategy to reduce out-of-pocket medication cost, and 17% perceived great difficulty paying for drugs (10% at both assessments). Restricting medication use at 1 year was more likely among elders who had reduced out-of-pocket medication cost (OR = 5.3, 95% CI: 1.2-22.4) or restricted medication use (OR = 10.7, 95% CI: 3.0-37.6) at baseline or reported great difficulty paying for medications (OR = 11.9, 95% CI: 3.6-39.9) at 1 year. Perception of great difficulty paying for medications at 1 year was associated with consistently having to choose between purchasing food and drugs, having no drug coverage, or using the largest number of unique medications. CONCLUSION: Efforts are needed to identify older individuals at risk for medication self-restriction and develop strategies for minimizing cost-related behaviors, especially those that persist over time, that may threaten adherence to medication regimens.
