Medication opioid use disorder (MOUD) treatment is the first-line approach to the treatment of opioid use disorder (OUD). This analysis seeks to identify “critical access” MOUD facilities that ensure geographic access for MOUD patients. We use locational data from two public-use data sources: SAMHSA’s Behavioral Health Treatment Services Locator and DATA 2000 waiver buprenorphine providers. We identify the closest MOUDs to each ZIP Code Tabulation Area (ZCTA)’s geographic centroid. We then construct a difference-in-distance metric by computing the difference in this distance measure between closest and second-closest MOUD, multiplied by ZCTA population, ranking MOUDs by difference-distance scores. These data allow us to identify the top 100 “critical access” MOUD units across the continental U.S.
