Understanding critical factors associated with integration of community health workers into health and hospital systems.

Community health worker (CHW) models have been shown to improve health behaviors and health outcomes and reduce cost, particularly among low-income underserved populations. Consequently, health systems are increasingly employing CHWs to provide health services in clinical environments. A growing body of the literature suggests that effective integration of CHWs within the healthcare system is important to achieve the desired outcomes, but the question of how to achieve effective integration is less clear. This study seeks to explore the integration of CHWs within a large state university health system to identify factors critical to the effective integration of CHWs into the clinical care environment. We conducted a qualitative descriptive multiple embedded case study of the University of Illinois at Chicago's Hospital and Health Science System (UI Health). The embedded subunits of analysis were teams within the UI Health System that currently employ CHWs to assist with the provision of clinical care or services to patients. Data were collected via semi-structured interviews and document review. In total, six sub-units were enrolled, and 17 interviews were conducted with CHWs (n = 9), and administrators or healthcare providers (n = 8). Fourteen factors related to effective CHW integration were identified and organized in four categories: individual, team, organization, and community. Findings suggest that in addition to commonly recognized elements of effective CHW models including training, supervision, and the presence of a champion, programs must consider the organizational context in which the program is positioned as well as the ways in which both CHWs and the organization engage with communities served. This research can serve as a roadmap for health systems that seek to integrate CHWs within healthcare services and can be used to promote best practice in CHW integration.
