Why the study?

Latinos have disproportionately higher rates of uncontrolled hypertension and poor medication adherence, with limited data and no translation of adherence interventions in community-based primary care.

Does a culturally tailored, practice-based adherence intervention improve medication adherence in Latino patients with uncontrolled hypertension?

Population

148 Latino patients with uncontrolled hypertension and non-adherence to antihypertensive medications

Comparison

Culturally tailored, practice-based adherence intervention vs usual care

Design

Randomized controlled trial with open-label design

Follow-up

6 months

Key result

A culturally tailored, practice-based adherence intervention is being evaluated to determine its effect on medication adherence among 148 Latino patients with uncontrolled hypertension.

Structured PICO

Does a culturally tailored, practice-based adherence intervention improve medication adherence in Latino patients with uncontrolled hypertension?

P
Population
148 Latino adults with uncontrolled hypertension and non-adherence to antihypertensive medications, planned to be followed for 6 months.
I
Intervention
Culturally tailored, practice-based adherence intervention delivered by bilingual Health Coaches using an EMR-embedded script. Includes 9 patient-centered counseling sessions (6 biweekly for the first 3 months, then 3 monthly for the remaining 3 months) based on brief motivational interviewing.
C
Comparator
Usual care (standard hypertension treatment recommendations as determined by primary care providers).
O
Outcome
Rate of medication adherence at 6 months, assessed using electronic drug monitoring devices (EMD).surrogate

This study protocol outlines a randomized controlled trial to evaluate whether a culturally tailored, EMR-integrated health coach intervention improves medication adherence and blood pressure control among Latino patients with uncontrolled hypertension.

Limitations

  • Patient recruitment challenges including high refusal rates and competing priorities
  • Technical difficulties with the initial wireless electronic monitoring devices
  • Time constraints of patients to receive counseling calls during work hours
  • Inability of Health Coaches to comply with audiotaping counseling sessions due to time constraints

Cite This Study

Schoenthaler et al. (2015) conducted an RCT in Uncontrolled hypertension (n=148). Culturally tailored adherence intervention vs. Usual care was evaluated on Rate of medication adherence at 6 months. A culturally tailored, practice-based adherence intervention is being evaluated to determine its effect on medication adherence among 148 Latino patients with uncontrolled hypertension.
