The goal of this hybrid type III study incorporating a cluster-randomized trial is to assess the effect of a community health worker-led hypertension prevention and control program (CHPC) on the implementation outcomes and clinical outcomes among patient with hypertension in central Nepal. The main questions it aims to answer are: 1\. What is the level of implementation outcomes, including reach, adoption, implementation fidelity, and maintenance of the CHPC implementation strategy at the patient, provider, and health system levels? 2: What is the effectiveness of the CHPC implementation strategy compared to facility-based intervention on systolic BP via a cluster randomized controlled trial. 3: What is the implementation cost and cost-effectiveness of the CHPC implementation strategy? Participants will receive counseling and blood pressure monitoring services at their home every four months for a year by a community health worker. Researchers will compare if there is a significant difference in systolic blood pressure between those who receive this intervention and those who do not receive the intervention in the same community.
