A recent study published in BMC Public Health highlights the effectiveness and cost-efficiency of peer education in improving medication adherence among elderly patients with hypertension. The research, conducted at health centers affiliated with Mashhad University of Medical Sciences in Iran, suggests that engaging peers in the education process can lead to better health outcomes and more efficient use of healthcare resources.
Study Design and Methodology
The randomized clinical trial involved 74 elderly individuals (60 years and older) with grade 2 or higher hypertension who were undergoing treatment with antihypertensive drugs. Participants were divided into intervention and control groups. The intervention group received 45-minute training sessions once a week for six weeks, led by a peer who had well-controlled blood pressure and demonstrated strong communication skills. The peer educator delivered content based on the Ministry of Health's standard educational package for blood pressure control. The control group received similar education from a health center nurse.
Medication adherence was measured using the Morisky Medication Adherence Scale (MMAS-8) before the intervention, immediately after, and at 3- and 6-week follow-ups. The direct costs of implementing the training sessions were also calculated for both groups to determine cost-effectiveness.
Key Findings
The study found that peer-led education significantly improved medication adherence compared to traditional nurse-led education. The cost-effectiveness analysis further revealed that peer education was a more efficient method for enhancing medication adherence in this population. The average cost-effectiveness ratio (ACER) was used to determine the cost per unit improvement in medication adherence score.
Implications for Hypertension Management
These findings suggest that peer education is a valuable strategy for hypertension management in elderly patients. By leveraging the experiences and communication skills of peers, healthcare providers can enhance patient engagement and improve adherence to medication regimens. This approach not only leads to better clinical outcomes but also offers economic benefits by optimizing resource allocation.
Ethical Considerations and Trial Registration
The study was approved by the Research Vice-Chancellor and the Ethics Committee of the University of Medical Sciences with the code IR.MUMS.REC.1397.086 and registered in the Clinical Trials Center of Iran with the code (IRCT20180519039710N1). All participants provided informed consent, and the confidentiality of their information was assured.
