- Brief Summary
MI-CARE is an innovative coordinated care team intervention to improve medication adherence and blood pressure derived from research findings that build on existing clinical practice. Designed with an eye toward sustainability, MI-CARE incorporates billable pharmacist and CHW services for patients with low medication adherence and high burdens of chronic illness and preventable consequences. MI-CARE offers interprofessional team care with comprehensive expertise and complementary skill sets that mitigate the silo effect of specialized medicine to deliver primary care to diverse, high-risk populations experiencing disparities in hypertension.
- Detailed Description
MI-CARE is a practice-based randomized controlled trial (RCT) to test the effectiveness of a comprehensive, individually- and culturally-tailored intervention for high-risk patients with hypertension, polypharmacy, and low adherence. MI-CARE leverages the specialized expertise of a clinical pharmacist together with a community health worker (CHW) who will serve as a cultural broker and patient navigator to address individual, clinical, social-cultural, and structural barriers to adherence.
This comprehensive and tailored, coordinated care intervention aims to improve medication adherence and hypertension outcomes among African-American, Latino, and Vietnamese immigrant patients. The proposed practice-based RCT is designed to meet the following specific aims:
Aim 1: Implement MI-CARE, an innovative, tailored adherence intervention delivered by a pharmacist and CHW team.
Aim 2: Determine the short- and long-term effectiveness of MI-CARE by assessing pre- to post-intervention changes in a) medication adherence (proximal outcome) and blood pressure (BP, distal outcome), and b) other comorbid health outcomes (e.g., HbA1c, BMI) using a randomized controlled trial.
Aim 3: Identify factors associated with MI-CARE effectiveness including a) tailored intervention features, b)medication beliefs, c) barriers to adherence, d) intervention dose, e) health literacy and f) cultural group.
The investigators will follow an intention-to-treat randomized design using a waitlist control with 230 African-American, and Latino patients with hypertension and low (\<85%) medication adherence. Data collection via pill count, self-report, electronic health record, and clinical measures will assess medication adherence, BP, and other factors at baseline (pre-intervention) and at 6 months post-intervention.

Group Intervention Description MI-CARE Intervention My Interprofessional Care team for Adherence and Research Engagement (MI-CARE) Pharmacist-community health worker team providing coordinated care tailored to high-risk patients with hypertension. MI-CARE intervention participants will meet with the pharmacist-CHW team for medication optimization and tailored case management. Pill counts will be completed to assess adherence and BP will be measured at each visit to guide antihypertensive medication optimization and provide feedback to participants about their adherence and BP control. Intervention visits will be followed by a booster one month later.
- Primary Outcome Measures
Name Time Method Self-reported medication adherence (survey) Month 6 Medication Adherence Report Scale-5 (MARS-5) with 5-point Likert scale will be used (Minimum Value: 1; Maximum Value 5); Range of score (cumulative): 5(worst) - 25(best)
Objectively measured medication adherence (pill count) Month 6 The investigators will use dosage information from the pill bottle and refill history to calculate percentage adherence (the number of pills taken / the number of pills that should have been taken x 100). All chronic oral medications in current use will be counted. Percent adherence rates for each medication will be calculated as well as the mean adherence averaged across all chronic oral medications.
Blood Pressure Month 6 Systolic and diastolic blood pressure measured by a calibrated, automated sphygmomanometer
- Secondary Outcome Measures
Name Time Method HgbA1c Month 6 Hemoglobin A1c for participants with concurrent diabetes will be collected from electronic health record
Weight Month 6 Participant's weight will be collected from electronic health record
Body Mass Index (BMI) Month 6 BMI calculated using participant's height and weight will be collected from electronic health record
Lipid Month 6 Lipid panel including low-density lipoprotein (LDL) cholesterol level will be collected from electronic health record
Statin use Month 6 Use of statin medication for participants with dyslipidemia or clinical atherosclerotic cardiovascular disease (or risk \>7.5%) will be collected from electronic health record
