Research

The Hopkins Center to Eliminate Cardiovascular Health Disparities is conducting three primary research studies as part of its initial five-year award.

Project ReDCHiP (Reducing Disparities and Controlling Hypertension in Primary Care)

  • Design: Pragmatic trial to study health-system and clinic-level factors that affect implementation, quality improvement and reduction in disparities
  • Settings: Six (6) community-based practices in Baltimore, Maryland
  • Interventions:
    • Blood pressure (BP) measurement training for clinicians and staff
    • Patient care management targeting dietary strategies and medication adherence
    • Clinician education using health information technology to deliver audit/feedback and patient-centered communication skills training
    • Outcomes: implementation rates, guideline-concordant care, racial disparities in blood pressure control, sustainability

The Achieving Blood Pressure Control Together (ACT) Study

  • Design: Randomized controlled trial
  • Study participants: 265 African-American patients with uncontrolled hypertension
  • Setting: Urban community primary care practice
  • Interventions:
    • Hypertension self-management and problem solving training for patients
    • Training in shared decision-making for patients and their family members
    • Community health worker support
  • Outcomes: Blood pressure control at one year, costs, sustainability

Five Plus Nuts and Beans Study

  • Design: Three-arm randomized trial of:
    • Printed Dietary Approaches to Stop Hypertension (DASH) diet advice (only)
    • Dietitian-delivered DASH advice tailored to neighborhood
    • Written DASH advice plus a dietary supplement containing potassium, magnesium, vitamins C and D, and fish oil
  • Participants/Setting: 180 African-American adults with controlled hypertension on medications, seen in community practices
  • Outcomes: Change in 24-hour ambulatory blood pressure at 8 weeks, glucose, insulin, uric acid, costs
