Key result
Telephone outreach and in-person education linked to lower BP and improved knowledge in severe hypertension.
Why the study?
Hypertension disproportionately affects marginalized communities, and Black Americans experience lower rates of blood pressure control than non-Hispanic Whites.
Does a telephone outreach and education intervention improve blood pressure control in underserved patients with severe hypertension?
Does a telephone outreach and education intervention improve blood pressure control in underserved patients with severe hypertension?
Telephone outreach combined with skill-based in-person education can effectively reduce blood pressure and improve health literacy in underserved populations with severe hypertension.
Supports hybrid outreach-education for underserved severe hypertension; extends evidence to real-world cohorts with low BP control rates.
Purpose: Hypertension (HTN) disproportionately affects marginalized communities due to persistent healthcare disparities and socioeconomic barriers. Less than half of patients with HTN achieve blood pressure (BP) control, with Black Americans on antihypertensive medication experiencing lower rates of BP control (34.9%) compared to non-Hispanic Whites (45.0%). This pilot study evaluates the effectiveness of a telephone outreach intervention designed to improve BP control through self-management in a historically underserved population. Major Findings: This single-cohort, pre-post intervention study was conducted at a Federally Qualified Health Center (FQHC). Patients with severe hypertension were identified and contacted by trained student ambassadors (SAs). These SAs provided hypertension-specific health education, health goal-setting, guidance for self-monitoring blood pressure, and referrals to address health-related social needs (HRSN). During in-person classes, patients were educated on BP self-monitoring and goal setting regarding healthy lifestyle practices. Results from this study showed a reduction in SBP and DBP among engaged patients and improved hypertension knowledge. Conclusion: These findings suggest that telephone outreach, when combined with skill-based in-person education, can improve hypertension control in Black American populations.
