Summary

This trial tests whether a 'learning health system'—a structured partnership between juvenile justice agencies and community mental health centers—can improve the full continuum of substance use care for youth involved in the justice system. The approach uses local data to identify gaps and implement tailored solutions. The study will measure outcomes like treatment initiation, engagement, substance use-related health visits, and recidivism among youth aged 11-22 in rural Indiana counties.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Learning Health System (a system-level intervention to improve collaboration between juvenile justice and behavioral healthcare agencies)
What this could lead to
If successful, this could create a scalable model to connect justice-involved youth with substance use treatment, potentially reducing addiction and repeat offenses.
What could go wrong
This is a large, complex system-level intervention that may be difficult to implement consistently across counties. Results depend on real-world collaboration and data sharing, which can be challenging.
