Abstract
OBJECTIVES: (a) To evaluate efficacy of a pictorial medication sheet to improve adherence in veterans with heart failure (HF) and cognitive impairment (CI); (b) to describe acceptance of the intervention. BACKGROUND: CI is prevalent in HF and is associated with worsened medication adherence. The Veteran's Administration has developed a medication image library; however, use of images to improve adherence has not been tested. METHODS: Thirty-six veterans with HF and CI were enrolled and provided pictorial medication sheets and an optional alarmed pillbox. Adherence pre-and post-intervention was determined by 30-day pill counts. Acceptance was assessed from interviews. RESULTS: Twenty-seven veterans (75%) completed the study. Overall medication adherence was poor, however there was significant improvement from pre-intervention (M = 79.74, SD = ±16.98) to post-intervention (M = 84.74, SD = ±10.00) adherence (t(26) = 2.16, p < .05, Cohen's d = .42). CONCLUSIONS: This pilot study provides preliminary evidence that medication images improve adherence with complex medication regimens. The intervention was well received by patients.
