Clinical trial NCT01843751
Conditions: Opioid Dependence
Sponsor: University of Wisconsin, Madison
Start date: 2013-03-01; Completion date: 2016-02-01
Enrollment: 24 participants; Allocation: RANDOMIZED; Intervention model: PARALLEL

Brief summary:
The proposed work addresses critical health and public safety issues in the U.S. and in Wisconsin: the intersection of addiction and crime and the prevention of associated individual and public health complications. The results will provide justification for the expanded involvement of primary care in the treatment of substance-related disorders (opioid dependence in particular) and the prevention of their complications. As such, the project answers to federal calls for the expansion of substance abuse treatment into primary care settings and to objectives within the Alcohol and Drug Focus Area of Healthiest Wisconsin 2020.

Detailed description:
Addiction adversely affects individual and family well-being, public health, and public safety across the state of WI. Appropriate treatment can prevent myriad physical consequences of addiction, such as HIV, viral hepatitis, endocarditis, motor vehicle accidents and other trauma. Treatment to one addicted individual prevents 63 crimes per year-not including intimate partner and child abuse, which remain under-reported. An individual's contact with the WI criminal justice system constitutes a critical point for referral into supervised treatment to promote the recovery of the user and, hence, public health and safety. This project and related future work will help optimize prevention, intervention, and policy development targeting substance use, crime and related consequences. Specifically, the proposed work will 1) examine the impact of collaborative community treatment models involving generalist physician offices, specialist treatment facilities, and criminal justice, 2) examine HIV risk behaviors and their response to study conditions, and 3) disseminate results to state and national audiences to promote collaboration between criminal justice, specialist care, and generalist health care in reducing drug-related harms to individual and population health. There is a high prevalence of opiate dependence among the criminally involved. Buprenorphine/naloxone (Suboxone) is considered a well-investigated, highly effective medication-assisted treatment for opiate dependence, but it may only be supervised through the few specialist treatment facilities in the state, or by physicians who have historically been less likely to offer this service. The effectiveness of community physician treatment supervision has not been tested for those in the criminal justice system.

The proposed project seeks to test models to expand treatment access for substance dependent individuals. The project builds logically upon previous work by the PI. Substance dependent offenders are specifically chosen for investigation due to (1) the greater severity and prevalence of substance use problems and complications when compared to the more general adult substance-dependent population, (2) the impact of drug-related criminal behavior upon victims and upon the safety and well-being of our communities, and (3) the suitability of our team and community-based collaborators to conduct research with addicted offenders in order to promote individual recovery, public health, and public safety.

To contribute to knowledge regarding potential models for the expansion of treatment and supervision for substance dependent offenders, the current project and related future work will aim to:

1. Compare models of treatment involving (1) specialist-directed treatment followed by physician-office based treatment, and (2) physician-office-based treatment alone.
2. Determine if and to what degree a period of stabilization with specialist-directed treatment improves outcomes over physician-office-based treatment alone.
3. Clarify the optimal period of time for such a period of "specialist stabilization."

In this study, "stabilization" refers to a period of time at the front end of treatment during which the addicted offender participates in a more stringent set of supervisory conditions tied to their medication dispensing. This includes daily reporting for medication dosing and more frequent urine drug testing.

The primary study outcome will be time to commission of new crime. The primary outcome will be measured via the publicly available Wisconsin Circuit Court Consolidated Court Automation Program (CCAP) database. The Wisconsin Circuit Court Access website provides access to certain public records of the circuit courts of Wisconsin. The information displayed on the website is an exact copy of the case information entered into CCAP case management system by court staff in the counties where the case files are located. The court record summaries viewed are all public records under Wisconsin open records law and freely accessible to the public. The CCAP database will searched periodically for all enrolled study participants until data analysis has been complete.

Secondary outcomes include ongoing drug use as measured by urine drug testing, previously validated self-report measures; and treatment uptake and adherence. Secondary outcomes also include standardized measures of HIV risk behaviors, health services utilization, and cost benefit (societal perspective).

All subjects will be recruited via Journey Mental Health Center (formerly Mental Health Center of Dane County), which serves as the assessment unit for the Dane County Drug Treatment Court (DTC). This study will determine whether varying periods of initial stabilization in specialist treatment affects outcomes vs. physician-office treatment alone. The study will randomize 40 participants to one of 2 conditions characterized by the duration or lack of the "specialist stabilization period": 1) buprenorphine/naloxone via physician office (B-PO) x 10 months, or 2) buprenorphine/naloxone via specialist center (B-SC) x 3 months followed by B-PO x 7 months. Subjects will receive behavioral treatment and court supervision as usual. The primary outcome will be time to re-arrest/new crime. Secondary outcomes include ongoing drug use measured by 1) urine drug testing, and 2) validated self-report measures, treatment uptake and adherence, standardized measures of HIV risk behaviors, health services utilization, and cost benefit.

Arms: arm 1: Buprenorphine/naloxone via physician office (B-PO) x 10 months arm 2: Buprenorphine/naloxone via specialist center (B-SC) x 3 months followed by B-PO x 7 months. The specialist center in this trial will be a methadone clinic.
