Community Intervention to Reduce Cardiovascular Disease in Chicago (CIRCL-Chicago)
CIRCL-Chicago is a federally funded research program to improve high blood pressure (hypertension) control in the Chicago South Side community. In Chicago, the prevalence of high blood pressure is higher among Black than white residents, and that gap is widening.
The CIRCL-Chicago study will evaluate the effectiveness of a community-driven adaptation of the Kaiser hypertension bundle, a collection of interventions and strategies designed to increase blood pressure control rates. The bundle includes a high blood pressure registry (i.e., list of patients), education on blood pressure measurement and treatment, feedback on blood pressure control rates, regular follow-up visits for blood pressure measurement, medication recommendations, and links to community resources.
For this study, Northwestern has partnered with faith-based organizations (FBOs) and community health centers (CHCs) in the South Side of Chicago. This team-based approach will increase coordinated care between clinic and community settings to improve hypertension control for Chicago’s South Side residents.
