Objective: We studied whether care management is a pragmatic solution for improving population blood pressure (BP) control and addressing BP disparities between Blacks and Whites in routine clinical environments. Design: Quasi-experimental, observational study. Setting and Participants: 3,964 uncontrolled hypertensive patients receiving primary care within the last year from one of six Baltimore clinics were identified as eligible. Intervention: Three in-person sessions over three months with registered dietitians and pharmacists who addressed medication titration, patient adherence to healthy behaviors and medication, and disparitiesrelated barriers. Main Measures: We assessed the population impact of care management using the RE-AIM framework. To evaluate effectiveness in improving BP, we used unadjusted, adjusted, and propensity-score matched differences-in-differences models to compare those who completed all sessions with partial completers and non-participants. Results: Of all eligible patients, 5% participated in care management. Of 629 patients who entered care management, 245 (39%) completed all three sessions. Those completing all sessions on average reached BP control (mean BP 137/78) and experienced 9 mm Hg systolic blood pressure (P
