Authored by Brian Rosman, Research Director of the Massachusetts-based Healthcare for All (HCFA), this paper outlines how HCFA evolved from advocating on access issues to including healthcare cost control in their portfolio. In addition to an overview, the paper offers a timeline of HCFA’s cost control work, providing a breakdown of how the organization built expertise, developed relationships with stakeholders, and ultimately worked to influence a 2012 MA healthcare cost control law.
