Check it, change it: a community-based intervention to improve blood pressure control.

BACKGROUND: Despite the widespread availability of effective and affordable therapies, hypertension remains this country's most significant modifiable cardiovascular risk factor. Approximately 30% to 50% of individuals with hypertension currently fail to reach guideline-recommended target blood pressure (BP) goals. Although multiple interventions have been proposed to affect better hypertension control, the integration of multiple elements in a community-based program has not been evaluated to date. METHODS AND RESULTS: We created a broadly inclusive community-based initiative to control hypertension called Check It, Change It: The Durham Blood Pressure Challenge (CICI). We enrolled ≈2000 participants with hypertension in 8 ambulatory clinics across Durham County, NC. The CICI program engaged individuals by providing them with tools for self-monitoring and tied this information to their caregivers via a web-based portal (the American Heart Association's Heart360, a remote BP monitoring system). Additionally, the CICI facilitated clinical intervention of high-risk individuals using physician assistants and community health coaches. The primary outcome will be a change in BP during the 6 months postenrollment in the program, which will be compared with concurrent and historical control populations of nonparticipants. CONCLUSIONS: We think that this integrated and tiered approach will lead to improved BP control within 6 months. If successful, the CICI program has the potential to enhance community-level BP control.
