Medications for addiction treatment (MAT) are the standard of care for treating opioid use disorder (OUD) and reducing overdose deaths, yet demand for MAT providers has outstripped supply in the USA. Public policy and graduate medical education (GME) leaders have called for increased focus on addiction medicine training for resident physicians to mitigate this provider gap. We sought to characterize the current state of OUD training at the GME level by reviewing published literature on GME educational interventions designed to enhance the care of patients with OUD. We identified 31 articles describing 29 unique interventions. The majority of these articles detailed specific, reproducible interventions with outcomes, and tended to focus on training resident physicians in behavioral approaches to treat OUD, rather than MAT. Fewer than half of interventions involved direct patient care. MAT training is under-represented within the current landscape of educational interventions, despite MAT being the standard of care for OUD.
