A Study to Evaluate the Best Ways to Implement a Community Health Worker-supported Telehealth Program for Managing High Blood Pressure in Kenya (COMPASS)

November 4, 2026 updated by: University of California, San Francisco

Community-based Implementation of Hypertension Screening and Telehealth Systems in Kenya

This study will compare two strategies involving community health workers and telehealth to help control high blood pressure among rural residents in Kenya: basic steps including training, developing protocols, and engaging leaders for supervision, compared to these steps plus additional support from healthcare worker champions and support from an outside facilitator. The program will be tested in 16 health centers and their surrounding catchment areas in Kenya to determine which approach works best.

Study Overview

Detailed Description

The study's goal is to examine the implementation and effectiveness of two strategies for integrating a community health worker (CHW)-facilitated hypertension telehealth intervention into routine care at primary health centers operated by Kenya's Ministry of Health (MoH). Investigators will conduct a type 2 hybrid implementation-effectiveness cluster randomized trial across 16 MoH primary health centers and surrounding communities in Homa Bay County to compare the impact of core and enhanced strategies on uptake of CHW telehealth and population-level hypertension control at 18 months. A waiver of consent will be obtained for the collection of data for the primary outcomes. CHWs, clinicians, implementation champions, practice facilitators, clinic directors, CHW supervisors and MOH leadership will take part in the implementation, in-depth interviews and surveys.
