MI-BP - An mHealth Protocol to Improve Blood Pressure Control in African Americans with Hypertension
ABSTRACT
Background:
African Americans shoulder significant disparities related to hypertension (HTN), compared to whites, and HTN is a serious public health problem in the city of Detroit, MI, where the population is more than 80% African American. Connectivity through smartphones, use of home blood pressure (BP) monitoring, and newly-developed mobile health (mHealth) interventions can facilitate behavioral changes and may improve long-term self-care for chronic conditions, but implementation of a combined approach utilizing these methods has not been tested among African American patients with uncontrolled HTN. Because African Americans are more likely than other racial or ethnic subgroups to utilize the emergency department (ED) for ambulatory care, this presents an opportunity to intervene on a population that is otherwise difficult to reach.
Objective:
MI-BP aims to reduce health disparities related to HTN in our community by employing a user-centered intervention focused on self-BP monitoring, physical activity, reduced sodium intake, and medication adherence. We seek to test the efficacy of MI-BP (Michigan-Blood Pressure), a mHealth application for HTN self-management, on BP control (primary aim), as well physical activity, sodium intake, and medication adherence (secondary aim) in African Americans with HTN. This study also seeks to evaluate the cost-effectiveness of MI-BP when compared to usual care methods.
Methods:
This is a one-year randomized control trial (RCT) that will recruit individuals who have uncontrolled HTN from two ED’s in the city of Detroit, with a planned sample size of 396 randomized participants. Once a participant is deemed eligible, all study procedures and subsequent follow-up visits (8 total) are conducted at the Wayne State University (WSU) Clinical Research Service Center (CRSC).
Results:
The recruitment period for the study began in January 2018, and data collection is expected to conclude in May 2020.
Conclusions:
As the first of its kind conducted in an ED setting, MI-BP was designed to document the efficacy and acceptability of a multicomponent mHealth approach to help African Americans with uncontrolled BP modify their lifestyle to better manage their HTN. We expect to lay the foundation to sustainably reduce HTN-related health disparities through better integration of multiple behavior self-monitoring, and improve outcomes for those who traditionally rely on the ED for chronic disease care.
