This study, funded as part of the Robert Wood Johnson Foundation’s Systems for Action research program, evaluates the effectiveness of California’s CalAIM Medicaid Waiver program in integrating social service and public health organizations into Medicaid coordinated systems of care for individuals with complex health and social needs. CalAIM is designed to dismantle forms of structural racism by investing nearly $2 Billion in helping Medicaid health plans and medical providers forge stronger alliances with local social service organizations and public health agencies in addressing the complex health and social needs of Medicaid beneficiaries, including paying for nonmedical services needed by these beneficiaries.
