The "Check, Monitor, Control Hypertension" Study is a 24-month Randomized Trial in Houston Targeting African Americans Aged 55+. It Combines Pharmacist Counseling and CHW Support to Improve Blood Pressure Control in Hypertension Management.

Hypertension (high blood pressure) is a major health concern in the United States, especially among African Americans, who experience higher rates of uncontrolled blood pressure and related complications like heart disease and stroke. This study aims to improve blood pressure control in older African American adults through a community-based approach that combines pharmacist-led counseling and Community Health Worker (CHW) support.

The study will enroll 480 African American adults aged 55 and older living in the Greater Houston area who have a history of hypertension. Participants will be randomly assigned to one of two groups: Pharmacist-only intervention - Participants receive medication therapy management and education on blood pressure monitoring and lifestyle changes; Pharmacist + CHW intervention - In addition to pharmacist counseling, participants receive personalized support from a CHW to overcome barriers like transportation and food insecurity, plus eight group health workshops each year. Both groups will receive a digital blood pressure monitor and guidance on checking blood pressure at home.

This matters because African Americans face unique challenges in managing hypertension, including contextual factors and limited access to care. By combining medical expertise with community-based support, this study hopes to empower participants to take control of their health and improve hypertension outcomes.
