Leveraging Technology to Address Unhealthy Drug Use in Primary Care Settings

Leveraging Technology to Address Unhealthy Drug Use in Primary Care: Effectiveness of the Substance Use Screening and Intervention Tool (SUSIT)

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.

This study has 3 specific aims:

Aim 1 is to develop clinical decision support that assists primary care providers in carrying out a brief intervention.

Aim 2 is to assess the impact of the SUSIT on dose of substance use brief intervention received by patients.

Aim 3 is to gather preliminary evidence on the efficacy of the SUSIT approach for reducing moderate-risk drug use.

Inclusion Criteria:

• Substance use screening results (collected using the tablet-based screening tool) indicating current moderate risk drug use, based on a substance specific involvement score (SSIS) indicating current (past 3 months) use of at least one drug with a moderate risk level (SSIS 4-26), in the absence of any high-risk drug or alcohol use (SSIS 27+);
• Presenting for visit with a participating PCP

Exclusion Criteria:

• Prior participation in the study (i.e. participation in the SO study phase would preclude participation in the SUSIT phase);
• Attending a formal addiction treatment program (not including informal treatment such as Alcoholics Anonymous, Narcotics Anonymous), in the past 3 months;
• Pregnant (based on self-report).
