As more organizations forge clinical-community partnerships and join multi-sector collaboratives to address social determinants of health, we’re seeing healthcare, social service, and public health stakeholders use different words, terms, and definitions. This lack of clarity and precision in communication is muddying the waters, making it harder for partners to move upstream rapidly and effectively. In this webinar, national leaders in the upstream movement share lessons from the frontlines of implementation and policy. They highlight ways stakeholders in multi-sector collaboratives and clinical-community partnerships can better communicate about social determinants of health and health equity.
