This brief is one of a series of findings briefs
documenting disparities in geographic access to health
services for ZIP code tabulation areas (ZCTAs) containing
a high proportion of minoritized racial/ethnic residents.
This report looks at spatial availability and travel
burden for substance use disorder care at the ZCTA level.
The median distance to the nearest methadone
treatment program across all rural ZCTAs was 27.7 miles.
The median distance to the nearest methadone treatment
program for urban ZCTAs was 8.0 miles.
Overall, rural ZCTAs were more distant from the
nearest buprenorphine provider than urban ZCTAs at a
median of 8.0 versus 4.2 miles respectively.
Access to buprenorphine providers appeared poorest
for top American Indian/Alaska Native (AI/AN) ZCTAs with
11.9% of rural and 10.6% of urban top AI/AN ZCTAs being
more than 30 miles from the nearest buprenorphine
provider. It is possible that residents of these ZCTAs
are served by Indian Health Service providers.
