Collaborative Care for Polysubstance Use in Primary Care Settings (Co-Care)
Study Details
Study Description
Brief Summary
The purpose of this trial is to test the efficacy of a collaborative care intervention to address opioid- and/or stimulant-involved polysubstance use in adult primary care patients with moderate to severe substance use disorders (SUD). The primary aims are to reduce days of opioid use (illicit or nonmedical opioid use), days of illicit stimulant use (cocaine, methamphetamine), and days of heavy alcohol use.

Outcome Measures
Primary Outcome Measures
- Total days of use of opioids, stimulants, and alcohol heavy drinking [Month 4-6]
Days of opioid use are defined as days with any use of heroin or synthetic opioids, or nonmedical use of prescription opioids. Nonmedical use includes using prescription opioids more than prescribed (e.g., taking two tablets when the prescription indicates a dose of one tablet) or taking pharmaceutical opioids that were not prescribed to the individual taking them. Days of stimulant use are defined as days with any use of cocaine or methamphetamine. Days of alcohol heavy drinking are defined as days with 5+ drinks/day for men, 4+ drinks/day for women. This outcome measure is collected using single item questions based on the Addiction Severity Index. Patient participants are asked to specify the number of days of use in the past 30 days (range is 0-30 days, value=0 for substances that were not used). The assessment is self-administered using a computerized form.

-
Initiated MOUD treatment (buprenorphine, methadone, or XR-NTX) within the 30 days prior to screening, per patient self-report. Because substance use may fall rapidly with the initiation of MOUD, patients who recently started MOUD may already be in the process of making changes to their substance use that are not attributable to the intervention.
-
- Initiation is defined as starting a new MOUD treatment episode, after not receiving MOUD treatment in the prior 30 days
-
Initiated a SUD treatment program within the 30 days prior to screening, per patient self-report. Because substance use may fall rapidly with the initiation of a treatment program, patients who recently initiated treatment may already be making changes to their substance use that are not attributable to the intervention.
