This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Summary

This completed study tested whether community health workers (CHWs) and home blood pressure monitoring could help adults in rural South Africa control their high blood pressure. Over 770 participants were assigned to different levels of CHW support. The goal was to see if this approach could lower systolic blood pressure and increase the number of people with controlled BP (<140/90 mmHg). The study provides evidence for a scalable, low-cost strategy to manage hypertension in resource-limited settings.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Community health worker care model with home blood pressure monitoring
What this could lead to
If successful, this approach could provide a practical, low-cost way to manage high blood pressure in underserved rural areas, reducing heart disease and stroke risk.
What could go wrong
This is a completed implementation study, not a drug trial. The results may not apply to other regions or populations, and long-term sustainability of the program is uncertain.
