Who could benefit from this research
✓Could help
Adults with hypertension who struggle to access or adhere to their prescribed medications and could benefit from peer support and HIT-enabled guidance.
✕Less likely to help
Patients with well-controlled blood pressure or those without access to peers or technology may see limited benefit.
What this research studies
The project aims to reduce missed doses and improve blood pressure control by combining door-to-door peer medication delivery with health information technology. It builds on a pilot in western Kenya and will study how well this blended approach works in real-world settings. Researchers will assess how peers, teleconsultations, and data analytics can streamline medicine access, support patient activation, and coordinate care and pharmacy activities. The study focuses on implementation strategies to overcome cost, access, and trust barriers that hinder adherence.
Why it matters
Potential benefit: If successful, patients with hypertension could experience better blood pressure control and fewer cardiovascular problems through easier access to medications and supportive technology.
How similar studies have gone: Preliminary data from a pilot suggests improved adherence and BP, but broader implementation results are still being tested.
