Programs that fill gaps in fractured health and social services in response to local needs can provide insight on enacting integrated care. Grassroots programs and the changing roles of paramedics within them were analyzed to explore how the health workforce, organizations and governance could support integrated care. In this study, five concepts were identified for fostering integrated care in local systems: single point-of-entry care pathways; flexible and mobile workforce; geographically-based cross-cutting organizations; permissive regulation; and assessing system-level value.
