This study will determine the feasibility of a multifaceted approach to recruitment of normal and high-risk pregnant women and their children. Three inter-related tasks will support this comprehensive feasibility study. First, an interdisciplinary summit will occur early in the study focused on how best to mitigate risks and maximize benefits to children and families recruited in a future cohort. Second, the feasibility of a multi-faceted recruitment strategy will be assessed. Third, select pregnancy and birth assessments will be collected from recruited participants in this feasibility study while leveraging data across early childhood from existing resources, to inform Phase II study planning. This Phase I of the FL-DECADE study will provide valuable planning and feasibility data to be used for the national efforts to build a large, prospective cohort.

This proposal aims to test the impact of an empirically derived implementation strategy—under real-world conditions and across multiple child service systems—on successful adoption and sustainment of two evidence-based programs that address adolescent substance abuse: Treatment Foster Care Oregon (TFCO; formerly Multidimensional Treatment Foster Care) and Multidimensional Family Therapy (MDFT). The overarching goal of this proposal is to evaluate whether the integration of implementation fidelity (fidelity to the implementation process) with intervention fidelity (fidelity to the clinical intervention) can increase the probability that a new organizational site not only successfully adopts a program but develops the infrastructure to ensure it can sustain. This study will (a) evaluate the effect of stages of implementation completion coaching strategy (SIC-CS) on outcomes of program adoption and sustainment, (b) extend the SIC to include measurement of sustainment, and (c) examine cost and resource patterns most likely to yield sustainable programs.

Use of both opioids and stimulants is increasing, but little is known about how polysubstance use evolves over time and how it influences overdose risk. This project will use data from two groups at high risk for overdose: i) participants in the AIDS Linked to the IntraVenous Experience (ALIVE) study who inject drugs and ii)  participants in the new Stimulant Opioid Non-Injection Cohort (SONIC) study. This research will identify drug use patterns and their association with treatment and overdose over time – toward informing overdose prevention efforts and interventions to improve the U.S. opioid crisis.

Effective treatment for OUD has been shown to improve patient outcomes and reduce health care costs; however, evidence of this effect in primary care settings is severely limited. The health economic findings from this study will supplement the parent PROUD trial’s results regarding clinical effectiveness and implementation outcomes and provide critical contextual information for health systems and other health care stakeholders. The study will evaluate the economic viability of the PROUD collaborative care model for OUD—that is, from the perspective of the health care sector, to what extent do the downstream cost savings associated with improved patient outcomes offset the additional costs of the PROUD intervention? The specific aims are to (1) estimate the start-up and ongoing management costs of the PROUD intervention, (2) assess costs associated with health care utilization for patients who receive primary care treatment in PROUD and usual care clinics and have been identified with recognized OUDs before clinic randomization, and (3) estimate the economic value of the PROUD intervention, measured as net monetary benefit (NMB, incremental benefit minus incremental cost), from the health care sector perspective.

A more than 5-fold increase in the incidence of neonatal abstinence syndrome has been reported since 2000. Preliminary studies show that prenatal opioid exposure is associated with increased risk of impaired neurodevelopment. Five institutions (Duke University, Arkansas Children’s Research Institute, Cincinnati Children’s Hospital, University of Illinois at Urbana–Champaign, and University of North Carolina at Chapel Hill) have formed a consortium to develop strategies for the Phase II HEALthy Brain and Child Development Study. Research teams will develop instruments and strategies (recruitment/retention protocols, assessment batteries, and novel tools); conduct pilot studies (fetal and postnatal imaging, advanced imaging harmonization and quality control, assessment administration, biosampling) to evaluate instruments; and analyze available data, including imaging, behavioral, cognitive, and maternal data from studies on early brain development, to guide the Phase II study design. Upon completion, the consortium aims to conduct the Phase II study.

Although there are effective prevention and treatment programs and services to address opioid misuse, opioid use disorder (OUD), and overdose, gaps remain between those needing and those receiving prevention and treatment, in part because of a need to better understand how to make these programs and services most effective at a local level. The National Institutes of Health (NIH) and the Substance Abuse and Mental Health Services Administration (SAMHSA) launched the HEALing Communities Study to generate evidence about how tools for preventing and treating opioid misuse and OUD are most effective at the local level. This multisite implementation research study will test the impact of an integrated set of evidence-based practices across health care, behavioral health, justice, and other community-based settings. The goal of the study is to reduce opioid-related overdose deaths by 40 percent over three years. The University of Kentucky is partnering with academic institutions in three other states to study the impact of these efforts in 67 highly affected communities. The study will also look at the effectiveness of coordinated systems of care designed to increase the number of individuals receiving medication to treat OUD, increase the distribution of naloxone, and reduce high-risk opioid prescribing.

During the COVID-19 public health emergency, the Substance Use and Mental Health Services Administration relaxed regulations for take-home dosing of methadone, offering an opportunity to improve methadone treatment access and address racial and ethnic disparities. This project aims to address regulatory, legal liability, and financial concerns related to clinical practice changes in opioid treatment programs. The project will first review state administrative data and conduct qualitative interviews to inform the intervention approach. The project will then evaluate an opioid treatment program intervention involving take-home methadone and its effect on take-home dosing, retention in care, and health outcomes for Black/African American and Hispanic/Latino individuals who take methadone for opioid use disorder.

While the mu opioid receptor (MOR) antagonist naloxone has proven invaluable as an opioid overdose antidote, naloxone suffers from a very short duration of action (half-life is approximately 1 hour) and has been found to be less effective against newer, long-acting opioids, including fentanyl (half-life is approximately 7–10 hours). This leads to a highly lethal and increasingly prevalent phenomenon known as “renarcotization,” wherein an overdose patient revived with naloxone can re-enter an overdose state from residual fentanyl in the body. Thus, there is a critical need to develop a long-acting MOR antagonist formulation that can address renarcotization by providing multi-hour protection. The goal of this project is to reformulate naloxone using FDA-approved microencapsulation technology into a long-acting injectable (LAI) that can provide 12–24 hours of sustained antagonist activity in vivo. It will employ a proprietary Computational Drug Delivery™ software, called ADSR™, to perform in silico formulation optimization as well as to predict its in vitro dissolution and in vivo pharmacokinetic behavior.

Most opioid misuse begins during adolescence and young adulthood. Adolescence is the best time for prevention interventions in settings like school-based health centers (HCs), yet few programs focus on preventing initiation of opioid misuse. This study harnesses the power of video game interventions and incorporates components of effective substance use prevention programs to develop an evidence-informed intervention to prevent the initiation of opioid misuse in adolescents. In partnership with the national School-Based Health Alliance (SBHA), researchers will develop and test a new video game intervention, PlaySmart. It will build on our previous video game intervention that has demonstrated efficacy in improving attitudes and knowledge related to risk behaviors. The study will evaluate the game in a randomized controlled trial (RCT) in 10 school-based HCs and examine strategies for implementing PlaySmart in school-based HCs nationally. This research has considerable potential for wide implementation, reach, and impact on high-risk adolescents through school-based HCs.

According to SAMHSA’s 2017 National Survey on Drug Use and Health (NSDUH), 11.4 million persons in the U.S. report past-year opioid misuse; out of them, only 2.1 million individuals met criteria for an OUD. Very little is known about efficacious interventions for those who do not meet criteria for moderate/severe OUD (i.e., subthreshold OUD). The prevalence of subthreshold OUD in primary care settings is 5 percent to 10 percent, with higher rates (21 percent to 29 percent) among those receiving prescribed opioids. Although they are at high risk of developing moderate/severe OUD and/or dying from an overdose, little or no empirical evidence exists for pragmatic prevention interventions that can be adopted at integrated general medical settings. To study the efficacy of prevention interventions to arrest the progression from risky opioid use, researchers will test the efficacy of a STOP intervention in primary care settings. STOP adopts an early intervention approach, based on a collaborative care model to prevent progression to moderate/severe OUD, and consists of a practice-embedded nurse care manager who provides patient education and supports the primary care provider (PCP) in engaging, monitoring and guiding patients who have risky opioid use; brief advice delivered to patients by their PCP; and phone counseling of patients by behavioral health providers to motivate and support behavior change. Researchers will determine whether STOP reduces risky opioid use and examine the impact of STOP on progression to moderate/severe OUD, overdose risk behavior and overdose events in adults with risky use of illicit or prescription opioids.

Emergency department (ED)-initiated buprenorphine/naloxone (BUP) with referral for ongoing BUP is superior to referral alone in engaging patients with untreated opioid use disorder (OUD) in treatment at 30 days and is cost-effective. However, logistical barriers exist in translating research into practice. New BUP formulations such as the extended-release injectable BUP (CAM2038, XR-BUP) hold promise in addressing many of the barriers more effectively than sublingual buprenorphine (SL-BUP) by treating the patients’ symptoms for up to seven days. This study will recruit, train and provide resources to 30 ED sites throughout the U.S. using implementation facilitation strategies to address stigma and provide ED-initiated BUP for patients presenting with OUD who are not receiving medications for OUD. Once implementation is adequately achieved, the sites will conduct a randomized controlled trial (RCT) to compare the effectiveness of SL-BUP versus XR-BUP on ED patients’ engagement in formal addiction treatment seven days after their ED visit. In addition, in an ancillary component of the study, the use of XR-BUP will be assessed in ED patients with Clinical Opioid Withdrawal Scale (COWS) scores of 4-7.
