Use of an Innovative Mobile Health Intervention to Improve Hypertension Among African-Americans

Not Applicable

Completed

• Conditions: High Blood Pressure
• Interventions: Behavioral: FAITH! App-enhanced Hypertension Intervention

• Registration Number: NCT04554147
• Lead Sponsor: Mayo Clinic

Brief Summary

The project objective is to test the feasibility of delivering health education and self-management support to African-American patients with uncontrolled hypertension (HTN) through a culturally-tailored smartphone application (app)-enhanced intervention within federally qualified health centers.

Detailed Description

The Fostering African-American Improvement in Total Health (FAITH!) Program at Mayo Clinic, a community-based cardiovascular (CV) health promotion initiative for African-Americans (AAs) will collaborate with the Minnesota Department of Health (MDH) Cardiovascular Health Unit and two federally qualified health centers (FQHCs) (NorthPoint Health \& Wellness Center, Minneapolis, MN; Open Cities Health Center, St. Paul, MN) to integrate an innovative mobile health (mHealth) intervention (FAITH! HTN App) into clinical and community settings with the aim of improving blood pressure (BP) control.

The project objective is to test the feasibility of delivering health education and self-management support to African-American patients with uncontrolled hypertension (HTN) through a culturally-tailored smartphone application (app)-enhanced intervention within federally qualified health centers. This initiative is a component of a Centers for Disease Control and Prevention (CDC) effort to support state/local public health strategies to prevent and manage cardiovascular disease (CVD) in under-resourced populations disproportionately affected by CVD risk factors, such as HTN. Insights from the FAITH! Community Steering Committee (CSC) will also provide guidance to ensure project patient-centeredness. The investigators will incorporate strategies grounded in theoretical frameworks to ensure soundness of our intervention while tailoring it to meet the preferences and needs of an under-resourced population with multi-level barriers to HTN management.

Specific Aim 1:To assess app feasibility through participant intervention engagement (app education module completion, self-monitoring) and intervention satisfaction.

Specific Aim 2: To assess preliminary efficacy of the app by evaluating improvement in patient BP control (immediate, 3 months and 6 months post-intervention), CV health knowledge (via app self-assessments), and BP self-management (medication adherence).

Hypothesis:

The study hypothesis is that an app-based intervention will be feasible and demonstrate preliminary efficacy in improving uncontrolled HTN and health education among AA patients from baseline to post-intervention (immediate, 3 months and 6 months post-intervention).

Arm && Interventions

Group	Intervention	Description
FAITH! App-enhanced Hypertension Intervention	FAITH! App-enhanced Hypertension Intervention	FAITH! HTN App: The program promotes HTN self-management through a 10-week education module series on HTN. Participants will follow each module weekly and use a wireless home BP monitor for self-tracking which syncs to the app. The app includes module quizzes, a BP tracking dashboard and a moderated sharing board to foster discussion on HTN management. Patient-Provider-CHW ICM. The patient-provider-CHW triad works together for personalized, collaborative goal setting. The patient will complete app modules, self-monitor BP, and engage with a sharing board integrating HTN topics. At weekly virtual visits (telephone or video), the CHW will record patient BPs, assist with addressing social determinants of health (SDOH) identified by the patient (eg, local community resources), and review HTN modules. The CHW will upload clinical/SDOH data to the patient electronic medical record (EMR) for FQHC care providers to review. This cycle will be completed weekly over the 10-week intervention.

Primary Outcome Measures

Name	Time	Method
HTN Self-Care Measures - Participant HTN self-care activities using the H-SCALE (Hypertension Self-Care Activity Level Effects)	6 months post-intervention	The 31-item instrument assess 6 HTN behavioral self-care activities recommended for optimal HTN management
Blood pressure (systolic and diastolic, mmHg)	6 months post intervention	Change from baseline blood pressure.
Intervention Feasibility Measures - Participant Engagement with Self-Monitoring	Time Frame: 6 months post-intervention	Participant engagement with weekly blood pressure tracking measured by number of times participant engaged with the blood pressure feature

Secondary Outcome Measures

Name	Time	Method
Preliminary Efficacy of Intervention - CV Health Knowledge as measured by module assessment scores	Immediate post intervention	Change in percentage correct scores (pre- and post- self-assessments) for each education module by patient and as a conglomerate (mean) for all patients.
Self Efficacy for Medication Adherence as measured by the MASES scale (medication adherence self-efficacy scale)	Immediate post-intervention	Change from baseline score. The 13-item instrument assesses patients' confidence in their ability to take their BP medications in a variety of situations.
Preliminary Efficacy of Intervention - BP Self-Management: Self-efficacy for HTN management	Immediate post-intervention	Change from baseline score. Self-efficacy to change health behaviors to manage HTN as measured by a 5-item instrument.
Social Determinants of Health (SDOH, PRAPARE (Protocol for Responding to and Addressing Patient Assets, Risks, and Experiences) tool)	Immediate post-intervention	Change from baseline PRAPARE score. The PRAPARE assessment tool will be used to calculate a tally risk score indicating the cumulative number of SDOH risks a patient faces (including 15 SDOH domains).
