The cost-effectiveness of peer education on medication adherence in the elderly with hypertension: a randomized controlled trial
Abstract
Abstract Background Peer education is an effective approach for promoting medication adherence in hypertensive patients, but there is limited evidence on its cost-effectiveness analysis. This study aimed to evaluate the cost -effectiveness of peer education for improving medication adherence in the elderly with hypertension. Methods This randomized clinical trial involved 74 elderly individuals with hypertension who were referred to health centers affiliated to Mashhad University of Medical Sciences in 2019. Educational content was presented over six sessions across six weeks by a peer in the intervention group, and a health center nurse in the control group. Data was collected before the intervention, immediately after intervention, and at 3 and 6 weeks post-intervention using the Morisky Medication Adherence Scale. Data analysis was performed by SPSS (Ver. 23) with both descriptive and statistical test. Cost-effectiveness analysis of the educational methods measured the impact on medication adherence scores for each group. Results The medication adherence score was 7.33 ± 0.41 and 6.37 ± 0.76 at 6 weeks post educational sessions in the intervention and control groups, respectively. There was a significant difference in mean score of medication adherence at the end of the intervention, as well as at 3 and 6 weeks post-intervention between the groups (p < 0.001). Additionally, the results indicated that peer education approach was more cost-effective than routine education. Conclusions Peer education programs promote medication adherence in elderly with hypertension and are more cost-effective than routine education in health centers. Healthcare managers can improve medication adherence and reduce costs with employing peers to educate older individuals with hypertension.
