Abstract
Community health workers (CHWs), or promotores de salud, have long played a role in health promotion, but the COVID-19 pandemic has brought renewed attention to the functions, sustainability, and financing of CHW models. ¡Andale! ¿Que Esperas? was a 12-month (June 2021-May 2022) campaign that expanded the CHW workforce to increase COVID-19 vaccination rates in structurally vulnerable, Latinx communities across California. This mixed-methods evaluation aims to elucidate (1) the role of CHWs in COVID-19 response, recovery, and rebuilding and (2) the importance, needs, and perils of CHW models in the COVID-19 era and beyond. CHWs facilitated 159,074 vaccinations and vaccine appointments by countering mis/disinformation, addressing mental health and social needs, building digital competencies, and meeting people where they are, all of which expanded access and instilled confidence in the COVID-19 vaccine. CHWs' success in engaging the community lies in their shared lived experience as well as their accessibility and recognition in the community, enabling their role in both immediate response and long-term recovery. Funding instability imperils the advances made by CHWs, and efforts are needed to institutionalize the CHW workforce with sustainable funding models. While Medicaid reimbursement models exist in some states, these models are often limited to healthcare services, overlooking a critical function of the CHW model: building community resilience and mobilizing the community for social change.
