Accountable Care Organizations

Accountable Care Organization Case Study

IHA is committed to the successful development of accountable care organizations (ACOs) as an effective integrated health care strategy and led a multi-year project to study the impact of ACOs on clinical quality, cost, patient experience, disparities, and vulnerable populations.  The case study, funded by the Robert Wood Johnson Foundation®, was conducted in collaboration with researchers at the University of California at Berkeley, School of Public Health.

The ACO case study focused on five California provider organizations implementing ACOs in the commercial, Medicare, and/or Medi-Cal market. The research team conducted interviews to obtain a comprehensive and multi-layered organizational view of the impact of ACO contracts and operations across all aspects of each organization.
