About us

The Health Care Transformation Hub is bringing together the people, research and expertise to fundamentally improve our nation’s health system. We are focused on exploring how patient-centered care enables better experiences for patients and doctors, higher quality care, better health outcomes and lower health care costs – for everyone.

Our mission is to advance research and discussion about care delivery that is centered around keeping patients healthy and supporting them when they are not, in contrast to the current health system, which can be frustratingly siloed and inconsistent in its quality. Value-based care represents a version of this vision, and there is growing consensus around the promise of this care model.

Value-based care means:
  • Preventive and holistic care for patients, resulting in better health outcomes and lower costs.
  • Clinicians are empowered with the time, tools and insights needed to provide high-quality care.
  • A simpler, less expensive and more responsive health system for everyone.

We aim to support the move towards patient-centered care by leveraging peer-reviewed research, thought leadership and collaborative partnerships to empower health care providers, policymakers and other health care stakeholders with actionable insights.

Together, we can tackle some of the biggest challenges facing health care today with credible research that will inform the health system of tomorrow.
