The Substance Abuse and Mental Health Services Administration Buprenorphine Practitioner Locator Misrepresents Access to Buprenorphine
Abstract: Aims: To compare county-level differences in the number of buprenorphine prescribers listed in the publicly available Substance Abuse and Mental Health Services Administration (SAMHSA) Buprenorphine Practitioner Locator and in the Drug Enforcement Administration’s (DEA) Controlled Substance Act (CSA) database and to determine if disparities in access exist in poorer areas with more non-white residents. Design: Cross-sectional study Setting: TexasMeasurements: County-level counts of buprenorphine prescribers were calculated from both the publicly available SAMHSA buprenorphine practitioner locator list and the DEA CSA database. These were then used to estimate the number of providers per 100,000 residents in each county. Regional variation in access to buprenorphine was compared descriptively across the state using poverty data from the US Census and county-level demography from the Texas Demographic Center. Results: This study found 68.8% more X-waivered providers on the DEA CSA database (n=2,622) with at least one provider reported in 125 of 144 counties in the state (49.2%) compared to the SAMHSA Buprenorphine Practitioner Locator (n=1,553) with at least one provider reported in 103 counties (40.5%). This difference was magnified in Texas Public Health Region 11. This is the poorest region of the state (23.7% of residents below the federal poverty line) and contains the most non-white residents 87.4% vs 54.9% (SD: 13.6%). This region had the lowest number of buprenorphine prescribers with 3.8 providers per 100,000 on the DEA CSA database and 2.5 providers per 100,000 in the SAMHSA Buprenorphine Practitioner Locator.Conclusions: The lack of a complete, public registry of buprenorphine prescribers makes it difficult for patients to identify a convenient buprenorphine prescriber and for referring physicians to help their patients access care. This may be especially true in poorer and more diverse areas with fewer buprenorphine prescribers.
