Overview

Addresses adherence gap in African Americans with hypertension; pilot RCTs will clarify feasibility before larger trials.

Study Design

Type

RCT (n=120)

Randomization

Block-randomized with a 1:1 ratio

Yes

Structured PICO

Does the BPMED text message system improve medication adherence and reduce blood pressure in African Americans with uncontrolled hypertension?

P
Population
A study protocol for two pilot randomized controlled trials aiming to enroll approximately 120 African American adults with uncontrolled hypertension to evaluate a 1-month text messaging intervention.
I
Intervention
BPMED text message system (automated text message medication reminders at times chosen by participant, plus 2 educational messages per week) for 1 month
C
Comparator
Usual care
O
Outcome
Medication adherence, medication adherence self-efficacy, and reduction in systolic and diastolic blood pressure from baseline to 1-month follow-up

This study protocol describes the development and planned evaluation of a text messaging intervention to improve medication adherence and blood pressure control among African Americans with uncontrolled hypertension.

Limitations

  • Reliance on a short-term 1-month follow-up
  • Dependence on small sample sizes
  • Lack of health care provider feedback in the design of BPMED
  • Lack of rigorous objective measures of medication adherence such as electronic pill bottles

Cite This Study

Buis et al. (2015) conducted an RCT in Uncontrolled hypertension (n=120). BPMED text message system vs. Usual care was evaluated on Medication adherence (measured by MMAS, pill counts, and self-report). The BPMED text messaging intervention was developed and is being evaluated in two pilot randomized controlled trials to determine its feasibility, acceptability, and preliminary efficacy for improving medication adherence in African Americans with uncontrolled hypertension.
