The fourth wave of the US opioid epidemic and its implications for the rural US: A federal perspective

Opioid use disorder (OUD) is a substantial public health problem. Buprenorphine is an effective medication-assisted treatment (MAT) for OUD, but access is difficult for patients, especially in rural locations. To improve access, the Comprehensive Addiction and Recovery Act of 2016 extended the ability to get a Drug Enforcement Administration (DEA) waiver to prescribe buprenorphine to treat OUD to nurse practitioners (NPs) and physician assistants (PAs). This study summarizes the geographic distribution of waivered physicians, NPs, and PAs at the end of 2017 and compares it to the distribution of waivered physicians 5 years earlier.
