Conditions

• Hypertension
• Blood Pressure

Interventions

BEHAVIORAL

Team-based Care Strategy for Hypertension Control

The core component of the intervention is a stepped-care protocol, based on the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) Clinical Practice Guideline for High Blood Pressure and the 2021 World Health Organization (WHO) Hypertension Guideline. Using a team-based care model, a physician-nurse-CHW team will work with patients to implement clinical guideline-based treatment in all intervention clinics. Team-based care components will include task sharing and shifting, health care team training, home BP monitoring, BP audit and feedback, and CHW-led health coaching on lifestyle modification and medication adherence.

BEHAVIORAL

Enhanced Usual Care

We will train the primary care physicians, nurses, and other clinic staff in performing standardized BP measurements. We will offer physician education on clinical guidelines for hypertension management and issue continuing medical education credits. Patient educational materials will be distributed. We will not conduct any other interventions in the enhanced usual care clinics.
