This study will assess the implementation of an evidence-based treatment in correctional settings by comparing the effectiveness of two medications used to treat opioid use disorder—extended-release buprenorphine (XR-B) vs. extended-release naltrexone (XR-NTX)—among adults currently incarcerated in U.S. jails and prisons at five distinct trial sites. This study will allow providers, correctional and public health authorities, payers, and policymakers’ timely and relevant data to assess the effectiveness of these medications as potentially useful re-entry treatment options. Findings from this study have implications for expanding public safety and limiting the societal costs of heroin, fentanyl, and prescription opioid addictions.

The Appalachian Node of NIDA Clinical Trials Network (CTN) will address clinical research questions that arise from Central Appalachia, an epicenter of the current opioid epidemic. Its rural geography, culture of independence, strained economy, and lack of access to substance use treatment have all contributed to the epidemic. The three aims of the node are to (1) conduct multi-site trials that address the current opioid crisis, with an emphasis on conducting studies among rural and other underserved populations; (2) propose studies to test innovative uses of existing resources to implement evidence-based practices that will extend state-of-the-art care into resource-poor regions, both rural and urban; and (3) disseminate CTN findings to regional payers and policymakers, practitioners, and the community. Proposed studies built on the work of node investigators include “Serious Bacterial Infections Related to Injection Drug Use: Quality Metrics and Intervention” and “Pharmacist-Assisted Buprenorphine Treatment,” among others.

People who inject drugs often have posttraumatic stress disorder (PTSD). Co-occurring PTSD puts these individuals at increased risk of illicit opioid use, opioid use disorder, overdose, HIV, and hepatitis C virus infection. This project will adapt, with input from the community, an evidence-based PTSD treatment program for people with both opioid use disorder and PTSD who are participating in a syringe service program. The treatment will then be tested in multiple syringe service programs to determine its potential for improving outcomes for these individuals who are often marginalized in traditional care.

Stigma is a key barrier to retention in medication-based treatment for opioid use disorder, particularly among low-income, minority individuals. Stigma that exists at multiple levels contributes to poor retention in care, including internalized and anticipated stigma at the individual level, as well as enacted stigma at the health care provider- and community levels. There is an urgent need to develop and evaluate innovative strategies to reduce stigma at these multiple levels among low-income, racial/ethnic minority individuals to improve engagement in care. One of the most promising strategies to reduce multiple intersecting stigmas simultaneously and improve engagement in care for low-income, minority individuals is through the use of peer recovery coaches (PRCs). PRCs, individuals who have gone through the recovery process themselves and are typically state-certified, have been shown to be more acceptable for engaging and retaining low-income, racial/ethnic minority patients in treatment compared to other health workers. However, scarce research has formally evaluated the effects of PRCs on stigma. This study will test how a PRC model can reduce multiple intersecting stigmas among low-income, racial/ethnic minority individuals to improve retention in methadone treatment.

Polysubstance use, especially use of both opioids and stimulants, is compounding the already devastating effects of the opioid crisis in underserved rural areas. This project builds on a previously established treatment model for opioid use disorder that uses telehealth and mobile treatment units, which seeks to engage people in activities they enjoy, to help them avoid negative behaviors such as drug use. This research will evaluate the effectiveness of a behavioral treatment approach delivered by peer recovery support specialists in rural areas and using mobile treatment units. The project will measure the intervention’s effect on treatment retention and polysubstance use – as well as evaluate the intervention’s feasibility, acceptability, adoption, and economic value.

As part of an ongoing teleECHO learning collaborative (LC),this study will expand clinical research training in evidence-based quality improvementmethods that were central to delivering and sustaining science-based medication-assisted treatment for opioid use disorder (MOUD) within the Vermont Hub-and-Spoke Model (HSM) with fidelity. Participating primary care practices will be trained in the (1) use of astudy-developedtoolkit of research and evaluationquality improvementmethodsintended to expand provider knowledge and performance in the delivery of evidence-based MOUD, (2) systematic tracking of standardized outcome metrics, and (3) sharing of these standardized data with other LC membersso that practices can use this empirical information to refine their care model over time. The study will measure changes in providers’ knowledge about best practices for MOUD, their comfort in caring for OUD patients with MOUD and their performance on all the standardized outcome metrics.

Very little research has been conducted on better understanding of phenotypic characterization of individuals with OUD (beyond DSM-5 diagnoses) and how these features predict illness severity, treatment retention or outcomes. The primary objective of the deep phenotyping study is to provide a comprehensive phenotypic characterization (e.g., domains of negative affect, reward salience, cognitive control, mental health) of a heterogeneous sample of individuals (n = 1,000) who currently meet one or more DSM-5 diagnostic criteria for OUD and are in treatment for OUD. In a subset of this sample (n = 100), the investigators conduct digital phenotyping to examine the utility of ecological momentary assessment (EMA), digital sensing and social media to predict retention, medication adherence and opioid use outcomes in patients receiving buprenorphine for OUD. It is anticipated that this foundational study will inform the feasibility and utility of such assessments that can be successfully embedded into imminent and future CTN and other OUD clinical trials.

Compared to people with stable housing, individuals experiencing homelessness are more likely to use both fentanyl and stimulants and experience drug-related harms. This project will examine fentanyl-stimulant polysubstance use patterns and how they evolve over time in response to changes to housing status. It will also assess use of overdose prevention and substance use disorder treatment interventions in homeless individuals who use both fentanyl and stimulants, including how polysubstance use patterns shape their risk of overdose over time. This research will also interact with community stakeholders toward translating the findings into future research, policy, and program recommendations.

Safe and stable housing is widely considered to be critical to recovery from alcohol and drug use disorders. Therefore, providing dedicated safe and substance-free housing options for individuals in recovery (recovery housing) may be an essential component of a comprehensive response to the current opioid crisis. However, there is limited evidence about effective recovery housing practices for individuals choosing treatment with medications for opioid use disorders as part of their path to recovery. This project will enhance the infrastructure necessary to study the effectiveness of recovery housing for these individuals. It will develop a national multi-stakeholder network, host webinars for researchers and recovery housing providers, and support mentored pilot studies for new researchers seeking to study recovery housing.

Although methadone is an effective treatment for opioid use disorder, many individuals drop out of treatment, putting them at risk of relapse and overdose. One of the factors associated with poor retention in methadone treatment is concurrent cocaine use. There is currently no effective medical treatment for cocaine use disorder. However, contingency management, in which individuals receive tangible rewards for desired behaviors such as abstinence, has been shown to be effective for cocaine use. This project will test the value of a digital therapy app, DynamiCare Health Contingency Management, in methadone treatment programs to promote treatment for polysubstance use.

The number of drug overdoses in New York continues to rise. In response, the New York State Office of Addiction Services and Supports (OASAS) is promoting approaches that embrace person-centered care, evidence-based practices, equitable treatment, and harm-reduction principles. In this project, researchers will partner with OASAS to build a quality measurement and management research center that provides performance feedback to support and encourage leadership and staff of treatment clinics to improve practice. The center will also publicize quality measures to ensure public accountability.

Among the more than half-million adults entering addiction treatment for prescription opioid abuse every year, 50%-60% report co-morbid chronic pain, and 80% report that pain triggers relapse. Individualized/self-stigma among adults with substance abuse has been shown to lead to delayed recovery, increased relapse and reduced treatment-related attendance. Stigma may induce significant burden on patients with OUD and chronic pain and there may be unique characteristics of stigma for this population due to the overlap between medical treatment and substance abuse. Multiple sources of stigma may be imposed including internalized/self-stigma as well as intragroup/peer-to-peer (?horizontal?) stigma whereby peers impose stigma upon each other based on the type and severity of past drug use. Furthermore, stigma could be ?vertical? in that stigma may be enacted by health care providers or by treatment center staff. However, there is notably a lack of research and related assessment tools to measure these multidimensional facets of stigma, particularly in patients with OUD and chronic pain. The investigators will utilize a mixed-methods approach to evaluate internalized/self-stigma, anticipated/expected stigma and enacted stigma using existing standardized surveys, and to describe horizontal and vertical stigma in individuals with OUD and pain at multiple sites. In addition, the investigators will integrate the quantitative and qualitative information to help inform modifications to the psychotherapy component (I-STOP) of the parent award intervention, which would then also target multidimensional stigma in patients with OUD and chronic pain.
