This toolkit from the American Society of Addiction Medicine (ASAM) provides a framework for organizing addiction treatment systems and a foundation for improving the quality of care for substance use disorder (SUD) treatment. The toolkit outlines the ASAM criteria, which offers evidence based guidelines for patient placement, continued stay, and transfer of patients with addictive, substance related and co occurring conditions. Its goal is to aid states in integrating the ASAM criteria into SUD treatment.
