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.

Chronic pain may be linked to poorer outcomes in those using medication-assisted treatments (MAT) to treat opioid use disorders (OUD). Psychosocial interventions for pain have been effective in patients with chronic pain and substance use disorders, but these interventions have not been thoroughly examined in the OUD population receiving MAT. The study team previously refined and adapted a psychosocial pain management intervention (PPMI) to be delivered by telephone for patients with OUD receiving MAT. The current study will understand the potential applicability of this intervention to other high-risk groups, such as veterans, study the longer-term impact of PPMI, and gather data to inform the implementation of PPMI in MAT patients. This work will provide a robust test of the PPMI intervention to help enhance MAT outcomes in a larger and more representative group of participants while also paving the way for future implementation of interventions to improve MAT retention.

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.

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.

Although approximately 80% of people with opioid use disorder smoke cigarettes, tobacco use is rarely addressed in treatment of opioid use disorder. Moreover, smoking cessation interventions that are effective in the general population have been minimally effective among people with opioid use disorder. This project will integrate into methadone treatment programs the Mindfulness-Oriented Recovery Enhancement intervention and motivational interviewing to address use of tobacco and other drugs. This research will determine the value of this intervention compared to attending a support group or receiving motivational interviewing. The project will also examine use of tobacco, opioids, and other drugs, and whether people begin treatment. The research will also study implementation barriers and facilitators to the mindfulness-based approach as well as strategies to enhance its adoption into clinical practice.

Research is needed to better understand how to make life-saving harm reduction services more accessible to populations that are hard to reach. This project will identify the physical and psychological factors that make harm reduction services most effective. The findings will then be used to inform the development, implementation, and testing of an innovative strategy consisting of several internet- and smartphone-based tools designed to improve access to harm reduction services for people who are hard to reach. 

Harm reduction supplies include fentanyl test strips that allow people who use drugs to identify whether the substance(s) they plan to take contain fentanyl and sterile syringes that help to prevent the spread of infectious diseases among people who inject drugs. One potential way to increase access to harm reduction supplies is mail delivery. This project will describe state-level policies that deter the use of mail-based delivery of harm reduction services, examine characteristics of people who use mail-based harm reduction services, and assess individual preferences related to mail-based harm reduction services.

Access to harm reduction services are often limited in rural areas. Secondary distribution is a potentially promising strategy for rural areas that involves people sharing harm reduction supplies such as naloxone or fentanyl test strips with other people who use drugs that do not come into contact with harm reduction service providers. This project aims to examine drug use and use of harm reduction services among people in rural communities, as well as highlight factors that make people more or less likely to use secondary distribution approaches.

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.

While some people who use drugs do not carry or use naloxone, others respond to multiple overdoses over short periods of time. This project aims to identify characteristics and experiences of these individuals, known as “overdose responders,” toward better understanding barriers to naloxone use. The research will also test interventions to support the well-being of responders and to increase the number of community members ready and willing to give naloxone to reverse overdose. 

Opioid Use Disorder (OUD) prevalence has reached unprecedented levels among adolescents and emerging adults. Recovery Support Services (RSS) for persons with SUDs typically focus on the individual client after acute care. But for youth, developmental theory underscores the primacy of family-level risk and protective factors, and family-based interventions have the strongest empirical support. Yet there is a lack of research, clinical resources, and generalizable metrics focused on family-based RSS for youth with OUD. This study will establish a sustainable research network to develop and evaluate innovative family-based RSS across the youth OUD services cascade. The overall goal is to conduct research to strategies to promote family integration in youth OUD services, increase service engagement, and build supportive family environments for youth recovery. The specific goals focus on 1) innovations in family RSS interventions and metrics to assist youth OUD providers with integrating families in OUD services and, 2) innovations in measurement of direct-to-family RSS for families of youth with OUD. If successful, this study will systematically build a research and technical assistance infrastructure designed to develop and evaluate innovative family-based RSS for youth with OUD that span all phases of the services cascade: screening and referral, treatment initiation, treatment delivery, and continuing care.

The opioid epidemic in the United States is associated with alarming rates of overdose and overdose deaths. Medication Assisted Treatment (MAT), in combination with psychosocial intervention, is the most effective treatment for OUD; however, many individuals are unable to access treatment, are not sufficiently retained in treatment, or experience barriers that prohibit their participation in treatment. A multipronged approach is needed that includes 1) development of integrated networks of care, both formal and informal, to better address the needs of individuals with OUDs and 2) measures of the efficacy of these integrated networks for addressing the needs of individuals with OUD. This project will build a learning collaborative to address gaps in knowledge about the delivery, sustainability, and assessment of recovery service for individuals on MAT. The collaborative will foster collaboration and communication between stakeholders and with the larger community of research and providers interested in improving the delivery of OUD recovery support services. This community-academic partnership will address the lack of evidence regarding effective recovery support services.

The opioid crisis has been particularly devastating to adolescents and young adults between 16 and 25 years old. Recovery support services in community settings can help these individuals who take medications for opioid use disorder find a path to recovery. This project will develop a network of advanced researchers, recovery support specialists, adolescents and young adults in recovery, and other key community stakeholders to help rapidly advance the science of recovery support services. This research will focus in particular on continuing care services specialized for adolescents and young adults who currently take or who have taken medications for opioid use disorder.
