Abstract

Introduction: Nearly half of American adults (47%) have hypertension (HTN), and non-Hispanic Black patients are disproportionately represented among those diagnosed (56% versus 48% for White, 46% for Asian, and 39% Hispanic adults). Models of care to reduce blood pressure for the Black patient population are not consistently implemented, in large part due to systemic and structural barriers to care. Hypothesis: The purpose of this study was to improve access to and use of digital education, skills for self-measured blood pressure (SMBP) monitoring, use of the electronic health record (EHR) patient portal, and blood pressure from baseline to 3 months in a cohort of Black Americans. Methods: A pre-post intervention design was used to evaluate the team-based, nurse-led intervention. Patients received coaching on HTN goals, screening for social determinants of health (SDOH), medication review, self-paced portal-based videos, and teach-back for BP cuff use. Post-implementation blood pressure (BP) and self-management (knowledge, cuff-use, patient portal use, and attendance at follow-up) were measured using the HELM tool, Chronic Care Model (CCM) and American Heart Association (AHA) HTN toolkit. 12-month follow-up is ongoing. Results: Black participants (n=80) averaged 59 (SD 10) years of age; most were female (n=58, 73%), employed (n=59, 75%), non-smokers (n=66, 84%), with average BMI 34.5 (SD8). From 0-3-months, views of portal-pushed videos increased to 69%, knowledge scores improved pre- (M = 67.9, SD = 16.7 to post (M = 75.2, SD = 17.4), and mean systolic BP was significantly reduced by 20.3mmHg (95%CI 16.11, 24.44). Average systolic BP pre was 152.13 (SD = 16.87) and post was 131.85 (SD = 13.13), t (79) = 9.71, p< .001. Sustainability at 12-months is ongoing. Conclusions: A team-based, nurse-led model improves patient engagement, adoption of portal-prescribed education, skills for SMBP, EHR-reported BP, and visit follow-up for Black patients with uncontrolled BP.
