Implementation Evaluation of a Combination Intervention for Sustainable Blood Pressure Control in Rural KwaZulu-Natal, South Africa

The study aimed to determine whether home-based care improves outcomes over standard, clinic-based blood pressure management in rural South Africa.

The study compared three treatment strategies: 1) standard of care (SOC), clinic-based management of hypertension, 2) a community blood pressure monitor-based model, in which individuals received blood pressure cuffs to measure their blood pressure at home, and were monitored by nurses via community health workers (CHW) with treatment decisions made via nurses remotely via a mobile health-based clinical decision support tool, and 3) an enhanced community blood pressure monitor-based model that included home-based blood pressure cuffs that transmitted readings over cellular networks directly to clinic-based nurses (eCHW+).
