The Greater Intermountain Node

The Greater Intermountain Node (GIN) was founded in 2019 to expand the existing National Institute of Drug Abuse Clinical Trial Network (CTN) infrastructure by developing and testing innovative interventions for opioid use disorder, preventing overdose, expanding the settings for Network research, and bringing new research expertise of opioid addiction research to the Utah, regional, and national communities.


The Greater Intermountain Node (GIN) is housed within the Program for Addiction Research, Clinical Care, Knowledge, and Advocacy (PARCKA) at the University of Utah. The GIN brings particular expertise in three areas of opioid addiction research to the Utah, regional, and national communities:

  1. Research within non-addiction specialty health care settings.
  2. Addiction and opioid research within large health systems of care.
  3. Implementation science and approaches to bring addiction evidence based research to practice.

The GIN leverages robust institutional commitment and infrastructure, institutional centers focused on addiction-related research, and training programs with strong regional and national connections to clinicians, educators, other institutions and organizations, and community stakeholders.
