Chronic Disease and Health Outcomes of Older Adults with Opioid Use
Funded by: National Institute on Drug Abuse
Project dates: May 2018 - April 2025
Principal Investigator: Han, Benjamin

Older adults over 50 have high rates of substance use that will place increasing demands on the substance use treatment system. This study will use a mixed methods approach to:

  • Describe the prevalence and risk factors for high utilization of acute healthcare, high medical costs, multiple chronic conditions, and mortality among older adults with opioid use disorder
  • Examine staff and patient attitudes, acceptance, and barriers regarding the integration of geriatric models of care into opioid treatment programs
  • Develop and pilot test for feasibility, a geriatric-based care model for geriatric conditions and chronic disease management
