Drs. Posen, Keller, Elmes, Messmer, Gastala, and Neeb reported no potential conflict of interest relevant to this article. Dr. Jarrett is a consultant to Trevena, developer of an investigative agent, TRV734, for medication-assisted treatment of opioid use disorder. She receives research funding from the US Health Resources and Services Administration; the Illinois Department of Human Services; the Substance Abuse and Mental Health Services Administration of the US Department of Health and Human Services; the Gordon and Betty Moore Foundation; and the Coleman Foundation.
Efforts are in place to identify areas at greatest need of OUD-related medical services, such as heat maps that identify areas of increased utilization of emergency medical services for opioid overdose. State-run programs have been implemented to increase access, such as the Illinois Helpline (https://helplineil.org) that provides support and resources for patients, friends, family, and providers.
Novel solutions
Key strategies to increase access to care and slow the opioid epidemic include low-threshold prescribing of MOUD and mobile OTPs.41
Low-threshold MOUD prescribing models. Adoption of one of these models in a medical practice that provides MAR might increase absolute enrollment. A low-threshold prescribing model involves42:
same-day treatment
leniency with respect to abstinence periods and a concomitant substance use disorder
enhanced accessibility to MOUD through nontraditional medical settings.
Do not use oral naltrexone to treat OUD; this route of administration has limited supporting evidence.
Low-threshold prescribing is flexible in regard to patients’ needs and bypasses many of the barriers discussed in this article. Impressive multicenter success has been achieved by the CA Bridge program in California (https://cabridge.org), including an increase in recognition of OUD, treatment initiations, and outpatient engagement.25
The cost-effectiveness of low-threshold MOUD prescribing programs remains to be determined.
Mobile OTPs. In July 2021, the DEA authorized a mobile component to existing OTP registrants that is permitted to dispense methadone and buprenorphine. Mobile units are physically separate from the OTP but have similar functions, depending on available space. Services that cannot be provided on the mobile unit of an OTP must be available at its brick-and-mortar location.7 Logistically, OTP registrants no longer need a separate registration to implement a mobile unit, thus expanding care to patients in underserved or remote areas who often encounter barriers to access.43
Conclusion
Understanding the distinct clinical and accessibility benefits and limitations among available MOUD is essential for prescribing clinicians. Accessing treatment is limited by federal regulation, stigma, and the existence of health care deserts that limit access to necessary care for patients with OUD. Newer harm-reduction models, such as low-threshold prescribing and mobile OTPs, represent progress, but many patients remain untreated.
