This is a paper that reviews many of the different program models that have integrated medications for opioid use disorder (MOUD) with primary care. There is a table that provides a good overview of practice-based and systems-based models along with linkages in both the academic and gray literature for each model.
This paper emphasizes that greater integration of MOUD in primary care settings is one way to expand access to effective treatment for opioid use disorder.
