Abstract

BACKGROUND: Uncontrolled hypertension is a significant public health problem in the U.S. with about one half of people able to keep blood pressure (BP) under control. Uncontrolled hypertension leads to increased risk of stroke, heart attack, and death. Furthermore, the social and economic costs of poor hypertension control are staggering. People living with hypertension can benefit from additional educational outreach and support.

METHODS: This randomized trial conducted at two Community Health Centers (CHCs) in Massachusetts assessed the effect of community health workers (CHWs) assisting patients with hypertension. In addition to the support provided by CHWs, the study uses video narratives from patients who have worked to control their BP through diet, exercise, and better medication adherence. Participants enrolled in the study were randomly assigned to immediate intervention (I) by CHWs or a delayed intervention (DI) (4 to 6months later). Each participant was asked to meet with the CHW 5 times (twice in person and three times telephonically). Study outcomes include systolic and diastolic BP, diet, exercise, and body mass index.

CONCLUSION: CHWs working directly with patients, using multiple approaches to support patient self-management, can be effective agents to support change in chronic illness management. Moreover, having culturally appropriate tools, such as narratives available through videos, can be an important, cost effective aid to CHWs. Recruitment and intervention delivery within a busy CHC environment required adaptation of the study design and protocols for staff supervision, data collection and intervention delivery and lessons learned are presented.
