On March 21, 2019, the Roundtable on Population Health Improvement of the National Academies of Sciences, Engineering, and Medicine (the National Academies) convened a 1-day workshop to explore the broad and multi-disciplinary nature of the population health workforce. The workshop was held at the Keck Center of the National Academies in Washington, DC, and organized by a planning committee made up of members of the Roundtable on Population Health Improvement and population health experts. The main objectives of the workshop were to explore the following three topics that resulted from the Statement of Task for the workshop: Facilitating a population health orientation/perspective among public health and health care leaders and professionals; Framing the work of personnel such as community health workers (CHWs), health navigators, and peer-to-peer chronic disease management educators within the context of population health; and leveraging the competencies of public- and private-sector workforces, such as education, transportation, and planning, that are working to include a “health in all policies,” community livability, or well-being orientation in their activities.
