CA Hub and Spoke System: MAT Expansion Project

On April 21, 2017, the Department of Health and Human Services (HHS) announced $485 million in 21st Century Cures Act-authorized funding for 50 states, the District of Columbia, and four territories to address opioid abuse. The amount allocated to California is $44,749,771 for the first year of the State Targeted Response (STR) to the Opioid Crisis Grant program administered by the Substance Abuse and Mental Health Services Administration (SAMHSA).

California’s project is named “Medication Assisted Treatment (MAT) Expansion.” The grant focuses on two projects: The California Hub and Spoke System (CA H&SS) and the Tribal MAT Project. The MAT Expansion Project is projected to serve 20,892 individuals with Opioid Use Disorders (OUD) over the two-year grant period. The goals of the project are to implement the Hub and Spoke model in various areas throughout California which will improve access to Narcotic Treatment Programs (NTPs) and Medication Units in counties with the highest overdose rates, and also increase the availability of buprenorphine statewide and increase MAT utilization. The Tribal MAT Project will create a project designed to meet the specific MAT needs of California’s American Indian and Native Alaskan tribal communities.

The goals of the MAT Expansion Project are as follows:

  1. Implement the California Hub and Spoke System (CA H&SS) in various areas throughout California.
    1. Improve access to MAT services in at least 30% of counties with the top ten highest overdose rates.
    2. Expand access to integrated MAT services in urban areas.
    3. Increase the access to NTP and/or MUs in underserved areas by three clinics.
  2. Increase the availability and utilization of buprenorphine statewide.
    1. In coordination with other statewide efforts, increase the total number of physicians and NPs waivered to prescribe buprenorphine.
    2. Increase the statewide average of the number of opioid users served by each waivered physician/NP.
    3. Increase the availability of counseling services for buprenorphine patients and a variety of support services for MDs in primary care settings.
  3. Improve MAT access for tribal communities (Tribal MAT Project).
    1. Increase the total number of tribal waivered prescribers certified,
    2. Provide expanded MAT services that include tribal values, culture and treatments.

The MAT Expansion Project will also fund prevention activities such as prevention specialists, provision of naloxone, coordination with local opioid coalitions, and training conducted by the University of California, Los Angeles (UCLA) and the California Society of Addiction Medicine (CSAM). In addition, the project will conduct a statewide needs assessment and create a strategic plan. The CA H&SS will also participate in a Learning Collaborative, which is a vehicle to create the connection that is needed to have an effective network with bi-directional patient movement and team care. UCLA will conduct an evaluation of project efforts, which will include the required federal performance measures in addition to other data elements.
