The widespread misuse of opioids has underscored the need to develop nonaddicting pain medications. Chronic pain is a major factor contributing to insomnia, and sleep disruption due to chronic pain causes patients to seek relief, exacerbating the drive for prescription opioids. In opioid use disorder, withdrawal from opiates induces insomnia, posing an additional challenge for successful abstinence. This study aims to determine whether treatment of opioid withdrawal-induced insomnia with nociceptin/orphanin FQ receptor (NOPR) agonists will mitigate the drive for opiate use. A major component of the arousal/withdrawal circuitries resides in the locus coeruleus (LC), which expresses MOPRs. The study will determine whether and how the NOPR system engages LC circuits to reduce arousal and insomnia-related phenotypes and assess the hypotheses that 1) the NOPR system is a component of the endogenous sleep/wake regulatory system and 2) NOPR agonists can act as therapeutic interventions to reduce opiate use.

This study will (1) test pharmacologic and behavioral strategies to improve OUD pharmacotherapy treatment retention and to improve outcomes among patients who have been successfully stabilized on OUD medications and want to stop medication and (2) identify predictors of successful outcome and develop a stage model of relapse risk.

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.

In 2018, new opiate prescribing limits (SB 273) were implemented across West Virginia to combat the opiate misuse epidemic. This study will utilize quantitative and qualitative measures to determine the effect of the recent opiate prescription laws in West Virginia, how a change in policy affects the opiate misuse epidemic, and how communities may apply this knowledge more broadly. The research team will: 1) collaborate with the West Virginia Board of Pharmacy to ascertain changes in opiate prescribing habits before and after the start of SB 273 using an interrupted time series methodology, and 2) achieve broad and deep understanding of how SB 273 has affected prescribing practices and experiences amongst primary care physicians, specialists (pan physicians, surgeons, emergency room physicians, etc.), and patients who currently or previously utilized opiate medications.

Low back pain (LBP) is a common and costly condition. Spinal manipulative therapy (SMT) is a common mind-body intervention for individuals with LBP. Studies that have supported SMT have generally found relatively small treatment effects. The prior work of this research team has identified two mechanisms explaining the therapeutic effects of SMT: a reduction in spinal stiffness and improved activation of the lumbar multifidus muscle. Our research team has also developed accurate, non-invasive methods to measure these effects and their response to SMT. Our overall goal is to optimize SMT treatment protocols for patients with LBP. In this project, we will use innovative methodology to efficiently evaluate the effects of various individual treatment components toward an overall effect. Results of this project will provide optimized SMT protocols that will be ready for application in future randomized controlled trials examining the efficacy and effectiveness of SMT.

The national public health opioid crisis has disproportionately burdened rural white populations and American Indian populations. To address this crisis, the Cherokee Nation and Emory University public health scientists will carry out an opioid prevention trial to be conducted in at-risk rural communities in the Cherokee Nation (in northeast Oklahoma) with populations of white and American Indian adolescents and young adults. The study will expand and integrate two established intervention approaches, consisting of community organizing and universal school-based brief intervention and referral to further enhance their effects in preventing and reducing opioid misuse. These interventions, called CMCA and CONNECT, were originally designed to target adolescent alcohol use, but showed significant beneficial effects on use of other drugs, including prescription drug misuse. The expanded, integrated interventions will be tested in a community-randomized trial with the goal of new systems for sustained implementation within existing structures of the Cherokee Nation.

In 2015–2016, there were over 2 million adults with an opioid use disorder (OUD); 62% had a co-occurring mental illness and 24% had a co-occurring serious mental illness. Despite the effectiveness of treatment, many individuals never receive it, and when treatment is provided, quality is low. This is a critical treatment gap in a vulnerable and stigmatized population. Collaborative care (CC) aims to address these gaps by improving access, quality, and outcomes in primary care patients with common mental health conditions. However, CC has never been tested with co-occurring disorders (COD). In the team’s CC model for COD (CC-COD), the CC team includes a behavioral health psychotherapist, medications for OUD, pharmacotherapy for depression and post-traumatic stress disorder (PTSD), motivational interviewing (MI), problem-solving therapy, and Seeking Safety. A multisite, randomized pragmatic trial will be conducted to adapt, harmonize, and then test whether CC-COD improves access, quality, and outcomes for patients with comorbid OUD and depression and/or PTSD.
