Medication-assisted treatment access enhancement initiatives
Medication-assisted treatment (MAT) for opioid dependence provides medications to individuals diagnosed with opioid use disorder, usually with counseling and behavioral therapies. As of August 2017, the U.S. Food and Drug Administration (FDA) has approved methadone, buprenorphine, and extended-release injectable naltrexone for MAT. Methadone is only dispensed through Opioid Treatment Programs (OTPs) certified by the Substance Abuse and Mental Health Services Administration (SAMHSA); buprenorphine is distributed through OTPs and prescribers who complete mandatory training. Naltrexone can be prescribed by any provider authorized to dispense medications1. As of 2014, only 28% of people in treatment for heroin use received MAT2. Limited appointment availability and lack of prescribing physicians are often barriers to MAT3, 4; efforts to enhance access include expanding availability and capacity to provide MAT5, 6.

Our evidence rating is based on the likelihood of achieving these outcomes:
Reduced substance abuse
Increased substance use disorder treatment
Reduced overdose deaths
What does the research say about effectiveness?
Enhancing access to medication-assisted treatment (MAT) for opioid use disorder is a suggested strategy to increase use of treatment and reduce unmet treatment needs, particularly for individuals with low incomes, individuals in rural areas, and in the criminal justice system as well as to decrease the frequency and amount of opioid misuse and reduce opioid overdose1, 7, 8, 9.
Medications used in MAT, particularly methadone and buprenorphine, increase treatment retention, reduce opioid abuse and overdose deaths, and reduce related health and social problems such as crime and HIV when used as part of a structured maintenance treatment program with appropriate dosing and clinical oversight7, 10, 11, 12, 13, 14, 15. Such medications may also improve treatment retention and birth outcomes for opioid-dependent pregnant women1, 16. Using extended-release naltrexone, MAT may decrease opioid relapse among opioid-dependent adults in the criminal justice system17. In some cases, counseling and behavioral therapy may increase the effectiveness of MAT7, 12, 13.
Available evidence suggests that Medicaid coverage for buprenorphine appears to be associated with increases in its use in facilities that offer addiction treatment services18. Methadone maintenance use among Medicaid-enrolled adults in opioid addiction therapy is higher in states that allow reimbursement for MAT19. An assessment of a Baltimore-based effort to fund physicians’ MAT training and prescription licensing suggests increasing access to MAT is associated with decreases in opioid overdose deaths20. However, additional evidence is needed to determine the effects of initiatives that enhance access to MAT on the use of treatment and health outcomes.
How could this strategy impact health disparities? This strategy is rated likely to decrease disparities.
Implementation Examples
As of May 2023, the Substance Use-Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act (SUPPORT Act) requires all states to provide Medicaid coverage of FDA-approved drugs to treat opioid use disorder (i.e., methadone, buprenorphine, and naltrexone), along with related behavioral therapies and counseling21.
As of March 2022, Maine, Maryland, Michigan, Rhode Island, Vermont, and Wisconsin implement the Medicaid health home models for opioid dependence treatment, with funding from the Centers for Medicare & Medicaid Services22, 23.
In September 2022, the Health Resources and Services Administration (HRSA) issued grants to support efforts to establish new access points to medication-assisted treatment (MAT), enhance the MAT workforce recruitment and training, and build community infrastructure for MAT service provision in rural communities including tribal communities24. Beginning in 2022, the Substance Abuse and Mental Health Services Administration (SAMHSA) has committed up to $1.43 billion to support state and local efforts to increase access to MAT and recovery support services through the two-year State Opioid Response grant program25.
Vermont’s Hub and Spoke model is an example of community effort to build a workforce and create integrated treatment across settings26.
