What is the purpose of this trial?

This trial explores new methods to connect individuals with opioid addiction to treatment providers. It aims to enhance the process of identifying those who need medication for opioid use disorder (MOUD) and facilitate their access to care, particularly for those involved with the justice system. The trial compares two approaches: one that fosters collaboration between different agencies and another that employs traditional top-down methods. Individuals with a history of opioid use or those at risk who are being released to certain communities may be suitable candidates. As an unphased trial, this study provides a unique opportunity to contribute to innovative solutions for opioid addiction treatment.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that the TCU Opioid-Treatment Linkage Model (O-TLM) protocol is safe?

Research shows that specific safety information for the TCU Opioid-Treatment Linkage Model (O-TLM) is not yet available. This new method is still under testing and aims to improve the connection of individuals with opioid addiction to treatment.

This trial differs from typical drug trials, which usually test a new drug's safety. Instead, it evaluates how effectively this model can be applied in real-life situations, aiming to enhance public health and safety for those involved with the justice system.

Although direct safety data is lacking, the model focuses on improving current practices and teamwork, generally indicating a low risk for participants. If the trial involved a new medication, more specific safety information would likely be available. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the TCU Opioid-Treatment Linkage Model (O-TLM) because it offers a fresh approach to tackling opioid addiction by linking criminal justice and community health systems. Unlike traditional methods that rely on top-down directives, the Horizontal implementation approach emphasizes collaboration and stakeholder involvement to refine practices and overcome barriers. Additionally, the Vertical implementation approach uses a structured, hierarchical strategy to drive change through policy and regulatory shifts. These innovative approaches aim to create more effective, integrated systems for addressing opioid addiction, potentially leading to better patient outcomes and systemic improvements.

What evidence suggests that the TCU Opioid-Treatment Linkage Model is effective for opioid addiction?

Research has shown that the TCU Opioid-Treatment Linkage Model (O-TLM) aids people with opioid addiction by connecting them to treatment and recovery resources. This trial will compare two different implementation approaches of the O-TLM. The Horizontal implementation approach involves facilitated collaboration between the criminal justice system and community health services, which has improved access to care. The Vertical implementation approach uses a hierarchical structure and top-down regulatory changes to drive system change. Both approaches aim to reduce stigma and improve coordination among providers, enhancing public health and safety. This trial evaluates how these approaches can effectively help individuals receive the assistance they need. ^{1 2 3 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• TCU Opioid-Treatment Linkage Model (O-TLM)

Trial Overview

The TCU JCOIN project tests the Opioid-Treatment Linkage Model (O-TLM), aiming to improve screening, linkage to treatment providers, reduce stigma, and enhance public health and safety outcomes among justice-involved individuals.

How Is the Trial Designed?

Group I: Horizontal implementation approach Experimental Treatment 1 Intervention

The Horizontal implementation approach of the O-TLM intervention is accompanied by facilitated collaboration between Criminal Justice and Community Behavioral Health systems. Direct involvement of stakeholders with differing perspectives and buy-in from agency leadership and policymakers are key elements. The Horizontal approach involves first developing a prototype (including how to modify existing practices, overcome implementation barriers, and manage roles and responsibilities) that are tested and refined before being rolled out systematically to other units within an agency.

Group II: Vertical implementation approach Active Control 1 Intervention

The Vertical implementation approach of the O-TLM intervention relies on the traditional criminal justice system's typical use of a hierarchical structure and the use of a top-down implementation approach (i.e., administrative orders) for directing change. Top-down regulatory and policy changes are viewed as vital levers for driving system change.

Published Research Related to This Trial

A study involving 468 Medicaid-enrolled individuals found that a mobile engagement unit significantly increased access to outpatient substance use treatment services and methadone maintenance for those with opioid use disorder (OUD).

Participants transported by the mobile unit showed a 23 percentage point increase in outpatient treatment utilization and a 32 percentage point increase in methadone maintenance compared to those who accessed treatment through traditional referral routes, indicating the effectiveness of mobile units in connecting underserved populations to necessary care.

A study involving 570 participants in a 24-week trial found that using an individualized treatment rule to assign either extended-release naltrexone (XR-NTX) or buprenorphine-naloxone (BUP-NX) could reduce the risk of relapse in opioid use disorder (OUD) by 12% compared to random assignment.

The findings suggest that a simple treatment strategy, such as assigning XR-NTX to homeless individuals and BUP-NX to those with stable housing, could effectively prevent relapses, with a number-needed-to-treat of 14 to prevent one relapse.
