Tailored Approaches to Improve Medication Adherence

September 25, 2019 updated by: NYU Langone Health
The purpose of this study is to to culturally tailor a technology-based individualized adherence intervention for Black and Latino patients with uncontrolled HTN or T2DM, who are non-adherent to their medications, and determine its acceptability.

Conditions

Detailed Description

Using a randomized controlled trial design, this study will compare the efficacy of a tailored adherence intervention (TAI) to a single patient education (PE) session, on medication adherence among 40 high-risk Black and Latino patients with uncontrolled hypertension (HTN) who are non-adherent to their prescribed antihypertensive medications. Patients randomized to the PE group will receive a single tablet delivered patient education session at the baseline visit. Patients randomized to the TAI group will complete a tailoring survey at the baseline visit to identify the most salient adherence barriers to the individual, which will be used to create an individualized adherence profile. Following completion of the tailoring survey, patients will collaborate with the RA to identify the most suitable mix of intervention strategies for improving medication adherence (i.e., reminder aids, motivational interviewing, case management) that are matched to the barriers outlined on patients' individualized adherence profiles.

Health education videos on topics unrelated to medication adherence, hypertension or type 2 diabetes
Health education videos on topics unrelated to medication adherence, hypertension or type 2 diabetes
EXPERIMENTAL: Tailored Adherence Intervention
Tablet-based tailored adherence intervention matched to patients' most salient adherence barriers
Patients randomized to the TAI group will complete a tailoring survey at the baseline visit to identify the most salient adherence barriers to the individual, which will be used to create an individualized adherence profile. Following completion of the tailoring survey, patients will collaborate with the RA to identify the most suitable mix of intervention strategies for improving medication adherence (i.e., reminder aids, motivational interviewing, case management) that are matched to the barriers outlined on patients' individualized adherence profiles.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Feasibility of Retaining Study Participants Through the 3 Month Trial
Time Frame: 3 months
Feasibility is assessed as the absolute number of patients that are retained in the study once they are consented and enrolled at baseline.
3 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Mean Systolic and Diastolic Blood Pressure at 3 Months
Time Frame: baseline and 3 months
Change in mean systolic and diastolic blood pressure readings from baseline to 3 months. Systolic and diastolic blood pressure are measured in mmHg using a validated automated blood pressure monitor. The average of three readings was used as the blood pressure measurements for the baseline and 3 month study visit.
baseline and 3 months
Change From Baseline in HbA1c at 3 Months
Time Frame: baseline and 3 months
Change in HbA1c from baseline to 3 months using a validated point-of-care device (Afinion AS100 Analyzer) at baseline and 3 months.
baseline and 3 months
Change From Baseline in Self-reported Medication Adherence at 3 Months
Time Frame: Baseline and 3 months
Medication adherence will be assessed by self-report using the validated 8-item Morisky Medication Adherence Scale. Scores range from 0-8, with higher scores indicative of better medication adherence.
Baseline and 3 months
