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.

The project will apply natural language processing to a rich repository of suicide and other clinical electronic health record and vital statistics to detect opioid problem-related encounters in order to (1) explore the relation between suicide risk and opioid misuse and (2) test whether a Zero Suicide model?s intervention effect is moderated by opioid misuse and whether it can also help to reduce opioid-related harm. First, the team will extract opioid-related EHR data using a combination of diagnostic codes and natural language processing, validated by structured manual chart review using a standardized procedure. Next, they will analyze the interplay between suicide risk and opioid problems in encounters and patients within the repository. Third, they will assess the effect of Zero Suicide implementation on prospective fatal and non-fatal suicidal behavior in patients with an opioid problem and examine whether the implementation had an effect on the incidence of opioid-related outcomes, including intentional overdose.

Increasing primary care clinician intention and behavior to obtain waivers to prescribe buprenorphine for treatment of opioid use disorder and increase use of the Opioid Wizard, a clinical decision support tool, has potential for patient benefit. This supplement will provide support to evaluate a training tool as an intervention to reduce stigma in primary care clinics by integrating a stigma reduction training component into the Opioid Wizard training at multiple sites of the NIDA Clinical Trial Network. Primary care providers will be randomized to novel stigma reduction training, grounded in stigma science, or an attention-control training to determine whether stigma reduction training reduces provider stigma, increases intention to apply for a waiver to prescribe buprenorphine, and ultimately increase the likelihood that providers use Opioid Wizard. The proposed supplement will utilize the randomized controlled trial design embedded in the larger multisite trial to evaluate the Opioid Wizard tool to help primary care clinicians identify, diagnose, and treat patients with opioid use disorder while evaluating the effect of the stigma reduction training.

Due to the opioid misuse epidemic across the nation, more infants are being exposed to narcotics during fetal life and developing neonatal opioid withdrawal syndrome (NOWS) in the neonatal period. Critical gaps remain in our knowledge with respect to best practices for identifying and managing infants with NOWS and no large-scale studies have been published on treatments undertaken and later outcomes of infants with NOWS. To address these gaps in knowledge, the Advancing Clinical Trials in Neonatal Opioid Withdrawal Syndrome (ACT NOW) study will evaluate treatment options and improve clinical care of infants with NAS/NOWS. This collaborative effort will conduct two trials: 1) Eating, Sleeping, Consoling for Neonatal Withdrawal (ESC-NOW): a Function-Based Assessment and Management Approach (ESC Study); and 2) Pragmatic, Randomized, Blinded Trial to Shorten Pharmacologic Treatment of Newborns With Neonatal Opioid Withdrawal Syndrome (NOWS) (Weaning Study).

One novel approach to address the opioid crisis is predicting the likelihood of retention in treatment for opioid use disorder (OUD) by assessing someone?s risk of early departure from treatment. Current methods rely on providers intuition to identify when an individual is at risk of leaving treatment early in order to intervene. This intervention, when it happens, often comes too late. Mobile health (mHealth) and Machine Learning (ML) predictive analytics offer a new opportunity to personalize OUD treatment, improve retention in OUD care, and mitigate the risk of relapse and overdose episodes. Project Motivate will combine physiological and behavioral data from disparate sources in order to predict when an individual is at risk of early departure from OUD treatment. If successful, results of the study will save lives, and lower medical costs, municipal emergency response costs, recidivism, workplace accidents, lost workplace productivity and costs to families.

The United States is in the middle of two intertwined epidemics. Suicide and overdose deaths are at record levels. Opioid use disorder and mental illness are major contributors to both, with the highest death rates seen in people with co-occurring disorders (COD). This competitive revision tests whether enhancements to the collaborative care (CC) model adapted for co-occurring disorders improves retention in medication treatment and decreases suicide and overdose risk. The three additional components include: (1) education of family members about addiction and medication treatment; (2) training for family members to administer naloxone and on how to reduce opioid risk behaviors, and (3) implementation of Caring Contacts, a suicide prevention intervention. This study will examine patient and family member attitudes toward overdose education and naloxone in the population with COD; examine and then intervene with family members around patients? use of medication; and test in the COD population the effectiveness of universal suicide and overdose prevention programs.

Buprenorphine has been shown to be is an effective method for treating Opioid Use Disorder (OUD). However, despite its success, treatment retention rates are notoriously low ? about half of those seeking treatment will have dropped out within the first 6 months. One factor known to negatively impact treatment adherence is stigma. This stigma derives from not only being viewed as individuals with OUD, but even as individuals seeking medications for OUD as these medications often include other forms of opioids. Additionally, individuals with OUD often suffer from other conditions, including psychiatric illness, leading them to live with multiple stigmatized identities. This study will develop tools to assess stigma associated with OUD, seeking medical treatment for OUD, and mental health. This knowledge will then be used to adapt the parent award?s mobile Health intervention intended to overcome stigma barriers and increase adherence to buprenorphine treatment for OUD.

Neonatal opioid withdrawal syndrome (NOWS) has emerged as a tragic by-product of the opioid epidemic. Newborns whose mothers used opioids while pregnant can experience symptoms of opioid withdrawal in the days following birth, such as tremors, irritability, seizures, sleep, digestive, and feeding problems. However, little is known about the effect of antenatal opioid exposure on longer-term infant development over time. To address this gap in understanding, the ACT NOW Longitudinal study is examining a crucial developmental period from birth to two years of life through a comprehensive battery of assessments, including MRI imaging, neurodevelopmental behavioral assessments, and family report measures. This longitudinal cohort study is projected to include a total of 375 infants, 250 who were exposed to opioids and 125 matched controls.

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.

Mortality and morbidity related to suicidal behavior and opioid use disorder (OUD) have increased significantly over the past decade. These two public health crises are intertwined at multiple levels. Medications for OUD, especially buprenorphine, have been shown to decrease opioid use and reduce the multiple negative consequences of OUD, including fatal and nonfatal overdose, criminal justice involvement, infectious complications, and misuse of other substances. In addition, small randomized trials of buprenorphine treatment in treatment-resistant depression (with or without co-occurring OUD) suggest that buprenorphine reduces depressive symptoms and suicidal ideation. This large study will evaluate the effects of starting buprenorphine treatment on self-harm and suicide attempt among people with opioid use disorder, including those with and without co-occurring mental health conditions or other known risk factors for suicidal behavior. Comprehensive health records data from four large health systems serving a combined member/patient population of approximately 11 million will be examined for the overall effect of buprenorphine treatment on subsequent self-harm or suicide attempt, including differences in effects between patient subgroups and specificity of effects to buprenorphine vs other medications.

Opioid use disorder (OUD) is a significant public health problem in the United States. Particularly troubling is the rapid evolution of an opioid epidemic within the past decade, characterized by a surge in unintentional overdose deaths involving synthetic opioids, such as fentanyl. The current standard of care for opioid overdose is reversal with opioid antagonist naloxone. Naloxone is effective at reversing overdose from prescription opioids and heroin, but less effective when combating fentanyl, due to fentanyl?s high potency. Therapeutic monoclonal antibodies (mAbs) against fentanyl could overcome this problem by specifically preventing the drug from entering the central nervous system, averting overdose and attenuating opioid-induced respiratory depression. This study will develop and design of laboratory protocols needed to establish a Good Manufacturing Practice (GMP) process, quality assurance protocol, and stability profile for a new human mAb against fentanyl. Subsequent production of current GMP material will enable Good Laboratory Practice (GLP) toxicology studies in rats and dogs and eventually a Phase I/IIa clinical trial. This material will also be used in final opioid-induced respiratory depression studies in mice and non-human primates to confirm therapeutic efficacy of final drug product. If successful, these activities will enable filing for an investigational new drug application for this mAb candidate with the FDA.
