​The Health Systems Node is made up of research scientists and staff at research departments embedded within integrated HSN health systems and the VA, dedicated to public domain substance use disorder research. The health care delivery systems represent diverse structures, and typically include an integrated delivery system, the ability to define patient populations, and access to electronic medical and administrative records. The HSN is led by multiple Principal Investigator (Drs. Campbell, Weisner and Bradley). Current member organizations and research expertise are:
