For individuals with moderate to severe opioid use disorder (OUD), medication-assisted treatments (MATs) such as oral methadone and extended-release naltrexone (XR-NTX) are the gold standard in initiating and maintaining long-term recovery. Still, many patients struggle with persistent sleep disturbance and stress reactivity in the early stages of recovery, which drive relapse behaviors. This proposal constitutes a novel mechanistic approach to understanding the role of the orexin system in sleep disturbance and circadian rhythms of stress in OUD patients who are maintained on MATs and are early in recovery. This study will determine whether the FDA-approved sleep medication suvorexant (SUVO) improves sleep continuity and decreases diurnal measures of stress, and whether improvement of sleep/stress processes translates to improved OUD treatment outcomes. Its findings will fill critical gaps in our understanding of the role of the orexin system in sleep disturbance and circadian rhythms of stress that impact OUD recovery.

The opioid overdose epidemic is increasingly affecting urban, poor and predominantly minority populations in the U.S., including Washington, D.C., as indicated by rapidly increasing overdoses clustered in medically underserved, economically disadvantaged, largely African American areas of the District and many of the nation’s other largest cities. This study seeks to (1) develop, implement and conduct a preliminary evaluation of an integrated, community-based collaborative care model, employing peer recovery coaches and telepsychiatry services, to improve utilization and effectiveness of MOUD in Federally Qualified Health Centers (FQHCs) and (2) use a community-based participatory research approach to develop, implement and conduct a preliminary evaluation of outreach, engagement and recovery support interventions in nontraditional community settings (e.g., grassroots community groups, churches or religious organizations, soup kitchens, black barber shops or nail or hair salons).

Knee osteoarthritis is one of the leading causes of chronic pain and disability worldwide, affecting more than 30% of older adults. Rates of this condition have more than doubled in the past 70 years and continue to grow sharply, given increases in life expectancy and body mass index among the U.S. population. This project supports a scientist from a group underrepresented in biomedicine to expand ongoing clinical research comparing various non-medication-based treatments for knee osteoarthritis.

To enhance availability of cognitive behavioral therapy for chronic pain (CBT-CP), this study will 1) refine strategies to identify and recruit patients, finalize intervention procedures, and ensure data infrastructure and quality; 2) determine the effectiveness of online and telephonic CBT-CP on patients and pain severity and secondary outcomes, including depression, sleep, quality of life, and pain-related health care utilization, from the electronic health record; and 3) assess the cost and incremental cost-effectiveness of online and telephonic CBT-CP compared with usual care. Eligible participants will be randomized to one of two painTRAINER interventions or usual care. Interventions will be eight weekly 45-minute sessions of the online program or telehealth-style phone coaching by trained behavioral health specialists. Self-reported pain severity and secondary outcomes will be assessed at baseline and at three, six, and 12 months.

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.

Participants in many clinical trials do not represent the U.S. population. Racial/ethnic minorities are often underrepresented, as are people with lower socioeconomic status and lower education levels, who face additional barriers, such as lack of transportation or childcare. Thus, both recruitment and retention of such populations is challenging, particularly for complementary and integrative health trials. This project proposes to enhance diversity, inclusion, and retention of participants in an ongoing study by creating a patient and caregiver Diversity, Recruitment, and Retention Advisory Board as well as adding a recruitment and retention specialist to coordinate the advisory board and implement necessary activities. The project will also provide evidence-based recruitment tools and will conduct structured interviews with patients who choose not to participate in a study as well as those who are at risk of dropping out to enhance understanding of the barriers and factors contributing to trial recruitment, loss to follow-up, and successful completion.

Acupuncture has been found to be effective in treating chronic lower back pain (cLBP) in adults. Yet trials have rarely included older adults, who have more comorbidities and may respond differently from typical trial participants. To fill this gap, the study team will conduct a three-arm trial of 828 adults ?65 years of age with cLBP to evaluate acupuncture versus usual care. They will compare a standard 12-week course of acupuncture with an enhanced course of acupuncture (12-week standard course, plus 12-week maintenance course) to usual medical care for cLBP. If successful, this pragmatic RCT will offer clear guidance about the value of acupuncture for improving functional status and reducing pain intensity and pain interference for older adults with cLBP.

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.

This study seeks to address the priority of the optimal duration of buprenorphine treatment to reduce the risk of relapse, overdose and mortality outcomes using observational data. Answering this question with a randomized trial raises ethical concerns. Observational studies with large datasets can address these important questions relatively quickly. At the same time, observational studies pose their own methodologic challenges related to confounding, misclassification of exposure and outcome, and informative loss to follow-up. This study will identify and quantify the potential for these sources of bias and then conduct analyses to address the questions of interest (risk of relapse, overdose and mortality).

The opioid crisis continues its highly negative impact, with more than 49,000 opioid-related overdose deaths in 2017. In 2016, the Centers for Disease Control and Prevention (CDC) issued guidelines for opioid prescribing that included opioid dosing and risk mitigation strategies, and health systems implemented similar initiatives even earlier. This has resulted in a quickly changing and more conservative prescribing environment. National data indicate the number of prescriptions has fallen between 2013 and 2016. Registries and electronic health record (EHR) data are increasingly cited as valuable resources to address critical research questions on opioid use with high efficiency. To our knowledge, no investigators have established an EHR-based prescription opioid registry across several diverse health systems with common data algorithms with the flexibility to address multiple questions. The goal of the proposed research is to develop a prescription opioid registry across 10 diverse health systems with harmonized EHR data from years 2012-2018 and leverage it to answer several key “next-step” research questions in response to the opioid crisis. The registry will include medications prescribed for treatment of OUD, including buprenorphine products.
