Leveraging Technology to Address Unhealthy Drug Use in Primary Care Settings

This study will develop a clinical decision support tool that assists primary care providers in carrying out substance use interventions, and then compare (in Phase 2) two clinical scenarios, screening only (SO) vs. SUSIT, (on dose of substance use brief intervention received) and changes in drug use at 3 and 6 months, among primary care patients. Investigators will develop the Clinical Decision Support (CDS) component and then test the full SUSIT approach, using mixed methods to assess its acceptability and adoption, and gathering preliminary data on its efficacy for reducing unhealthy drug use. CDS development is concurrent with the SO phase to avoid losing valuable time, but will be conducted at a secondary study site to avoid contaminating the SO condition.
