Region 10 Addiction Technology Transfer Center - The University of Washington Addiction, Drug, & Alcohol Institute (UW ADAI), a core Department of Psychiatry and Behavioral Sciences program, is applying for the 2024-29 funding cycle to administer the Northwest Addiction Technology Transfer Center (Northwest ATTC) in Health and Human Services Region 10 (HHS R10). Since its initial funding in 2017, the Northwest ATTC at UW ADAI has accelerated adoption and implementation of useful treatment and recovery practices via technical assistance (TA) among a workforce serving persons with substance use disorders (SUDs). Taken alongside regional contribution to SAMHSA’s Opioid Response Network, collective efforts by Dr. Hartzler’s experienced team will continue to involve collaboration across HHS R10 and a UW campus community nationally-renowned for advancing addiction research, policy, and clinical practice. We propose a comprehensive program of TA for the addiction workforce in HHS R10 states of Alaska, Idaho, Oregon, and Washington, over a five- year period. The program of TA is aligned with a conceptual framework established by SAMHSA for the TTCs to encompass: 1) basic TA, for which the intent is to promote awareness of a given practice; 2) targeted TA, for which the intent is to improve attitudes, knowledge, skill, for that practice by individual workforce members; and 3) intensive TA, for which the intent is to support a community or organization in instituting systems-level changes to enable and reinforce practice implementation by workforce they employ. Accordingly, proposed basic TA activities include, but are not limited to, a monthly webinar series of 60 presentations on a range of SUD-related topics, creation of online trainings such as a Harm Reduction for SUD Settings product. Proposed targeted TA activities include, but are not limited to, 20 annual training offerings on topics such as Clinical Supervision and Motivational Interviewing, Addiction Medicine Project ECHOs and learning collaboratives on topics like Reducing Sexual Risk and Pre-Exposure Prophylaxis, and recurrent State Stakeholder meetings to generate strategies to improve workforce recruitment and retention. And proposed intensive TA activities include, but are not limited to, annual sponsorship of a Tribal Clinical Supervision Immersion Program for those supervising workforce in indigenous communities, two multi-regional projects with ATTC Network partners to support implementation of caregiver-led Invitation to Change groups and to create a Management and Supervision Institute for Behavioral Health Leaders, and multiple annual projects to support health organizations in HHS R10 to implement a new practice or organizational process. In summary, the Northwest ATTC at UW ADAI proposes to offer a comprehensive program of TA, with projection to reach 1500 addiction workforce members per award year, over this five-year period to strengthen capacity of the HHS R10 addiction workforce across an SUD care continuum that spans prevention, harm reduction, treatment, and recovery. Estimated number of people to be served as a result of the award of this grant: 7500.
