The Drug and Alcohol Clinical Advisory Service: A model of telephone-delivered addiction specialist support.

DACAS is providing a multistate-level response to the challenges of accessing specialist addiction treatment, particularly for opioid agonist treatment and other opioid issues, with demonstrated uptake in regional and remote areas. This telephone-delivered service provides an opportunity to expand access to treatment for opioid use disorder and other substance use problems, particularly in areas with less equitable access to specialist addiction care.
