Interprofessional collaboration between social workers and community health workers to address health and mental health in the United States: A systematised review.

Collaboration between social workers (SW) and community health workers (CHW) plays an essential role in addressing health inequities in the United States (US). However, little is known about the current state of CHW/SW collaboration. The objectives of this review were to identify (a) the nature, goals and setting of CHWs and SW collaboration; (b) the patient outcomes utilised to measure intervention efficacy. The literature search was conducted in December 2020 using six databases. The inclusion criteria were (1) interventions that included CHWs and SWs; (2) US-based; (3) published between 2000-2020; (4) peer-reviewed journal articles; (5) examining health or mental health outcomes. Search results identified 281 articles, and 15 were included in the final analysis. Settings that utilised SW/CHW collaboration included outpatient clinics (n = 10); community organisations (n = 4) or hospital (n = 1). CHW and SW interventions focused on disease prevention (n = 8), chronic care (n = 4) and mental health (n = 3). Health outcomes were the most evaluated (n = 13), and significant improvement of at least one health outcome was reported in those studies. Mental health outcomes (n = 3) were also significantly improved, while social determinants of health (n = 2) were least common and descriptive only. This is the first review of SW and CHW collaboration. Clarity regarding SW and CHW roles and scopes of practice are needed to understand better SW/CHW collaboration and its impacts on community health outcomes and improve the process of collaboration. SW and CHW collaboration may increase clients' access to preventive care, mental health and address health inequities.
