Comparative Study Effectiveness of Clinical Decision-Making Processes Required by Public Health Systems Study

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

California counties are in the process of implementing a Centers for Medicare and Medicaid Services Medicaid 1115 Substance Use Disorder (SUD) demonstration. The demonstration requires that patients be assigned to addiction treatment settings and levels of care systematically, using comprehensive biopsychosocial assessments and guided by the American Society of Addiction Medicine (ASAM) patient placement criteria. RTI International, a nonprofit research institute, and University of California Los Angeles (UCLA) Integrated Substance Abuse Programs have been awarded a contract from the Patient Centered Outcomes Research Institute (PCORI) to study the effects of the ASAM implementation in California. The California 1115 SUD demonstration provides a unique opportunity to learn about the benefits and challenges resulting from system-wide implementation of ASAM criteria. The study will involve surveying patients in counties that are using the ASAM criteria and in counties that have not yet adopted the ASAM criteria. Medicaid patients receiving addiction treatment will be offered the opportunity participate in the study and to be surveyed about their experiences in treatment. The study will also analyze data from the California Outcomes Management System (CalOMS) and conduct interviews with providers, patients, and policymakers in the state. The results of the study will help inform California's efforts to continually improve its addiction treatment systems to better meet the needs of it communities. This study will also produce important and useful information to patients seeking treatment for addiction, and their providers, SUD system administrators, and payers.
