Improving Access to Evidence-Based Medical Treatment for Opioid Use Disorder: Strategies to Address Key Barriers Within the Treatment System

| Even though evidence-based treatment for opioid use disorders (OUD) is eff ective, almost four in fi ve Americans with OUD do not receive any form of treatment. The gap in access to evidencebased care, including treatment with medications for OUD, stems in part from barriers to change within the health care system. This paper includes nine key barriers that prevent access to evidence-based care, including stigma; inadequate clinical training; a dearth of addiction specialists; lack of integration of MOUD provision in practice; regulatory, statutory, and data sharing restrictions; and fi nancial barriers. Action from a number of actors is urgently needed to address this crisis.
