Applying the RE-AIM framework to evaluate an educational model to “close the gap” and improve health equity in uncontrolled hypertension

Abstract

ObjectivesTo use the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework to evaluate an educational model addressing self-management of uncontrolled hypertension. MethodsWe used a pre-post single cohort design to identify minoritized patients with uncontrolled hypertension (systolic > 160 mmHg and/or diastolic > 100 mmHg). Trained Ambassadors provided telephone outreach, skill-based blood pressure (BP) monitoring, and goal-setting for 4 months. Follow-up occurred at 7 months. We evaluated the initiative using the RE-AIM framework and quantitative analysis for process and outcome measures post-intervention. ResultsAmong Black patients (n = 345), the average age was 55.4 years (8.7), half identified as male (n = 173, 50.1 %); many were uninsured (n = 159, 46.1 %). Engagement in calls occurred for 67.8 % (n = 234) of the cohort; monitor distribution was 22.9 % (n = 79); and goal setting occurred for 64 patients. BP improved for 40 % of the cohort (mean pre: 168/98 mmHg, mean post: 150/89 mmHg; p < 0.0001) and 40 % of patients’ last known BP was < 140/90. ConclusionsRE-AIM evaluation of the Closing the Gap initiative suggests that the model is associated with BP reduction in high-risk Black patients. Practice ImplicationsAn educational model for patient-centered hypertension management in low-income populations is feasible and addresses self-monitoring barriers.
