The proposed study, "Check, Monitor, Control Hypertension in Older African American Adults," is a randomized clinical trial designed to improve blood pressure control among African American adults aged 55 years and older in the Greater Houston area. Hypertension disproportionately affects African Americans, contributing to higher rates of cardiovascular disease and stroke. This project aims to improve clinical and behavioral outcomes through a 24-month intervention combining pharmacist-led counseling and Community Health Worker (CHW) support.
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. Timeline \& Safety Recruitment begins: January 2026 Intervention duration: 24 months Primary completion date: May 2030 The study poses minimal risk, mainly mild discomfort from blood pressure checks. Privacy will be protected using HIPAA-compliant systems, and participation is voluntary.
