Opioid Use Disorder
Conditions
Brief summary
This is an observational, ancillary study intended to describe opioid use among opioid use disorder patients following their discharge into the community from inpatient detoxification and/or short-term residential treatment programs affiliated with parent study CTN-0051, which assessed the comparative effectiveness of extended release injectable naltrexone (XR-NTX, Vivitrol®), an opioid antagonist recently approved and indicated for the prevention of relapse to opioid dependence, versus buprenorphine-naloxone (BUP-NX, Suboxone®), a high affinity partial agonist indicated for maintenance treatment of opioid dependence, as pharmacotherapeutic aids to recovery.
Detailed description
Participant recruitment will begin after recruitment for CTN-0051 has been completed. Opioid use disorder patients will be recruited prior to leaving detoxification and/or short-term residential programs. Screening and baseline data (focused on demographics, diagnosis and service utilization) will be collected prior to discharge, and follow-up data (focused on opioid use) will be collected at weeks 1, 4 and 8 following discharge.
