Partners in Health: A Conceptual Framework for the Role of Community Health Workers in Facilitating Patients' Adoption of Healthy Behaviors

We formulated a conceptual framework that begins to answer the national call to improve health care access, delivery, and quality by explaining the processes through which community health workers (CHWs) facilitate patients’ adoption of healthy behaviors. In September 2011 to January 2012, we conducted a qualitative study that triangulated multiple data sources: 26 in-depth interviews, training documents, and patient charts. CHWs served as partners in health to immigrant Filipinos with hypertension, leveraging their cultural congruence with intervention participants, employing interpersonal communication techniques to build trust and rapport, providing social support, and assisting with health behavior change. To drive the field forward, this work can be expanded with framework testing that may influence future CHW training and interventions.Community health workers (CHWs) are laypeople from within the communities where they work, who share common characteristics with their patients (e.g., ethnicity, culture, race, and language).1–4 CHWs have demonstrated effectiveness in an array of conditions, ranging from maternal and child health to chronic disease management.4–12 A systematic review of randomized controlled trials on CHW effectiveness determined that CHWs address health issues among various ethnic and racial groups, help improve use of early intervention services for children at risk for developmental delay, improve screening for breast and cervical cancer, and aid in improving dietary behaviors and blood pressure control.10CHWs have specific training in providing basic nutrition and health promotion services; they aim to improve health care access through a set of core skills,13,14 advocacy, outreach, and education.2,15,16 They function in multiple roles: bridging communication between patients and providers, providing health education and counseling, and monitoring health status.7,12 Thus, CHWs have a tremendous potential to influence and improve health outcomes.Although CHWs play integral roles in supporting patients’ individual health behaviors,17–23 the processes through which they are influential are poorly understood.21 Increasing use of this model in the United States, and recommendations in the Patient Protection and Affordable Care Act to integrate CHWs as part of health care teams,24 underscore the need to advance the knowledge base surrounding CHWs and to better understand mechanisms of this role. We developed a conceptual framework to explicate the processes through which CHWs facilitate the adoption of healthy behaviors among their patients.
