Funded Projects

Neurostimulation techniques, such as transcranial direct current stimulation (tDCS), have been used as interventions for substance use disorders. This is a supplement to the currently NIDA-funded UG3 DA047793, “tDCS to Decrease Opioid Relapse,” which will measure behavioral and brain responses following tDCS stimulation delivered during tasks that use a particular brain network involved in cognitive control, and utilizing FMRI to assess the effects. This supplement allows the researchers to add an EEG measurement to the study, to get a complete picture of how tDCS might affect the function of key brain networks in ways that could be helpful for SUDs.

This supplement supports the goals of the current award, “An Evaluation of the National Zero Suicide Model Across Learning Healthcare Systems” (U01MH114087). Safety planning is a highly recommended practice within the Zero Suicide framework, but little is known about the effectiveness of the individual elements that can make up a safety plan, such as lethal means assessment, identification of supportive contacts, coping skills, warning signs, and sources of distraction. All of the documentation lives in text-based clinical narratives. This supplement will support development of new metrics using natural language processing to determine baseline rates, from which we can quantify the change in safety planning and lethal means assessment practice longitudinally after implementation of new safety planning templates using our Zero Suicide main award.

People who have anxiety and/or depression are particularly susceptible to misusing opioids to avoid negative emotional states. This project aims to develop and test a fully autonomous (no-human operator) cognitive behavioral therapy-based digital therapeutic for people with co-occurring opioid use disorder and anxiety or depression. The goal is to specifically target compulsive opioid use motivated by the relief of unpleasant emotions. The researchers will modify an existing digital therapeutic and test its efficacy in this patient population.

People with opioid use disorder (OUD) are at increased risk of depression and other mental health conditions, and a significant proportion of opioid-related deaths are likely suicides. Nearly 50% of patients who die by suicide make a healthcare visit in the month prior, most often to primary care. Yet systematic screening of patients with OUD for suicide risk is rarely done. Clinical decision support tools within the electronic health record can improve healthcare prevention measures and important clinical outcomes. This primary care-based clinic-randomized trial will integrate a clinical decision support tool for suicide risk prediction with a clinical decision support tool for the identification, diagnosis, and treatment of opioid use disorder. By integrating these two tools, the study will identify patients with opioid use disorder who have increased risk for suicide, ultimately increasing engagement in both OUD treatment and outpatient mental health care

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.

American Native (AN) communities experience high rates of trauma that compromise the mental health of parents and caregivers that in turn increases their children?s risk for suicide and substance use during adolescence and young adulthood. Without intervention, this intergenerational cycle may repeat. The goal of this study is to understand opioid use, suicide, and the social network characteristics of Fort Peck Assiniboine and Sioux parents and caregivers to determine how the social network of parents/adult caregivers are related to both risk for and protection from suicide and opioid use. This supplement will examine the effectiveness of a community health worker delivered, culturally tailored prevention intervention called Wa?Kan Ye?Zah on caregiver and child behavioral and mental health outcomes and assess the benefits of culturally enhancing the intervention for caregivers? well-being.

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.

As states make unprecedented changes to prescription opioid (PO) policies and cannabis laws, the independent and synergistic contributions that both types of measures have on opioid-prescribing practices and opioid overdoses, with and without benzodiazepines (BZDs), are not known. This study will pursue this aim in the U.S. population and Medicaid patients with chronic pain, aiming to: (1) examine whether nonmedical use of POs, BZDs, and heroin and opioid- and BZD-use disorders decreased following enactment of more restrictive PO policies and less restrictive cannabis laws in 2004–2019; and (2) test whether Medicaid patients are less likely to have claims for opioid prescribing, clinic visits for chronic pain, and opioid overdoses following enactment of more restrictive PO policies and less restrictive cannabis laws in 2001–2019. This study will provide findings about the types of policies that are most likely to end the opioid epidemic.

People who use opioids, as well as those who take medications approved by the U.S. Food and Drug Administration for opioid use disorder (OUD), report significant problems with sleep and biological rhythms. This project will explore the activity of a novel group of photosensitive neurons in the retinas, a potential source for sleep disturbances in these individuals. The research could lead to new treatment strategies and responses, but also may identify a non-invasive, circadian biomarker to predict recovery and relapse in people with OUD.

Data from 2015 show that American Indian/Alaska Natives (AI/AN) have the highest rates of diagnosis for opioid use disorders (OUD) and deaths from drug overdose; yet, there are no prevention programs addressing opioid misuse among urban AI/AN young adults that integrate culturally-appropriate strategies with evidence-based treatment. This project proposes to address that gap and help prevent OUD in Older Adolescents and Young Adults (ages 16-30) by developing and implementing a culturally-centered intervention to address opioid misuse among urban AI/AN emerging adults in California. The study will examine outcomes at 3-, 6-, and 12- months, and explore potential mechanisms of change for decreases in opioid and alcohol and other drug use outcomes through mediation analyses, including changes in social networks and cultural connectedness. Results from this study could significantly advance scientific knowledge and clinical practice for AI/AN emerging adults.

There is a great deal of research aimed at better understanding transitions in alcohol and other drug (AOD) use patterns from early to late adolescence and from late adolescence to emerging adulthood. However, no studies to date have (a) assessments of AOD use from ages 10 to 24 across all developmental periods (middle school, high school, and emerging adulthood); (b) a large sample with substantial racial and ethnic diversity, particularly among Hispanic and Asian youth; (c) in-depth coverage of 10 areas of functioning across three key domains; (d) subjective and objective neighborhood data; or (e) the capacity to examine developmental trajectories for more than one substance. The current proposal is a continuation of previous projects that assessed AOD use across nine waves of data from age 10 to age 19. The proposed study capitalizes on the longitudinal data on protective and risk factors we have collected since age 10 in an ethnically diverse cohort by continuing to annually assess these youth in order to capture important transitions to emerging adulthood (through age 24). By advancing the epidemiology of alcohol use during adolescence and emerging adulthood, our findings can affect prevention and intervention programming for young people and address critical issues of public health policy.

Repetitive drug use forms powerful memories associating drug-evoked experiences with its proximal environmental cues. Memories are major obstacles for successfully treating addiction, since even after a prolonged period of abstinence, reexposure to such cues often triggers craving that promotes relapse. A polysynaptic pathway from the paraventricular nucleus of the thalamus (PVT) to the lateral hypothalamus (LH) has been shown to play a role in the maintenance of the opioid-associated memories. Hypocretin (Hcrt) neurons in the LH strongly innervate the PVT, required for maintaining wakefulness and involved in drug seeking. These factors may link sleep disorders in opioid addicts with their long-lasting drug-associated memories. This study will (1) determine whether Hcrt neurons in the LH are the major target; (2) examine whether manipulating the LH (Hcrt)-PVT pathway can effectively prevent relapse; and (3) test whether sleep intervention could be an effective strategy to prevent relapse.

Quality implementation of evidence-based programs (EBPs) in community settings for youth is critical for reducing the burden of alcohol, tobacco and other drug (ATOD) use and its consequences. EBPs delivered in schools are an efficient way to reach large populations of young people, including those underserved by other settings, and reduce and prevent ATOD use. Yet youth rarely receive EBPs as intended in community settings, including schools. This training and research plan will prepare the investigator to become an independent scholar in the implementation of theories and frameworks to better understand factors related to program delivery—approaches to enhancing ATOD programs for youth in community settings. More specifically, the training will allow him to expand the application of Consolidated Framework for Implementation Research (CFIR) to inform approaches to enhancing effective EBP delivery. The proposed training and research plan extends current implementation research to focus applying implementation theories, frameworks and strategies in other community settings (schools) and on economic evaluation of implementation strategies. The results are expected to improve current efforts to deliver EBPs in diverse community settings and aid in applying evidence-based implementation strategies in the school context to ultimately reduce and prevent ATOD use among youth.
