Adapting and Implementing a Chronic Disease Self-Management Program for Primary Care Patients with Opioid Use Disorder and Serious Mental Illness Cross-Cutting Research Training the Next Generation of Researchers in HEAL NIDA UNIVERSITY OF UTAH SIANTZ, ELIZABETH Salt Lake City, UT 2023
NOFO Title: Career Development Awards in Implementation Science for Substance Use Prevention and Treatment (K01 - Clinical Trial Required) 
NOFO Number: PAS-22-206
Summary:

Many people with opioid use disorder (OUD) also have a serious mental illness and other chronic conditions, which can be difficult for individuals and primary care providers to manage. A chronic disease self-management program is an established health care model in which peers help to educate patients about their condition(s) and build problem-solving skills to manage their health. Such programs have been effective in other populations and settings, but they have not been adapted for primary care patients who have OUD and SMI. This project will adapt and test a chronic disease self-management program for this population to understand its feasibility, acceptability, impact, and how best to put such programs into place widely in primary care settings.

Workforce and System Change to Treat Adolescent Opioid Use Disorder Within Integrated Pediatric Primary Care Translation of Research to Practice for the Treatment of Opioid Addiction Optimizing the Quality, Reach, and Impact of Addiction Services NIDA INDIANA UNIV-PURDUE UNIV AT INDIANAPOLIS HULVERSHORN, LESLIE A (contact); AALSMA, MATTHEW; ADAMS, ZACHARY WILLIAM Indianapolis, IN 2023
NOFO Title: HEAL Initiative: Translating Research to Practice to End the Overdose Crisis (R61/R33 Clinical Trial Optional)
NOFO Number: RFA-DA-23-053
Summary:

The overdose crisis has expanded rapidly among adolescent populations in recent years, largely due to illicit substances containing lethal amounts of the highly potent synthetic opioid fentanyl. However, a provider shortage limits access to effective treatment for adolescents with opioid use disorder and other substance use disorders (SUD). Although primary care is a promising setting for expanding delivery of SUD treatment to adolescents, many primary care providers lack the training, resources, and support systems to deliver these services confidently and effectively. This project will leverage a large-scale rollout of integrated behavioral health care in a statewide health system. The research will test whether embedding behavioral health specialists into primary care visits, introducing case management and electronic clinical decision support tools, and reducing stigma will increase delivery of SUD treatment to adolescents.

Promoting Retention in Opioid Treatment among Women Experiencing Intimate Partner Violence: A Novel Stepped Care Model Targeting PTSD Translation of Research to Practice for the Treatment of Opioid Addiction Optimizing the Quality, Reach, and Impact of Addiction Services NIDA YALE UNIVERSITY SULLIVAN, TAMI P (contact); EDELMAN, E JENNIFER; JOHNSON, DAWN M New Haven, CT 2023
NOFO Title: HEAL Initiative: Translating Research to Practice to End the Overdose Crisis (R61/R33 Clinical Trial Optional)
NOFO Number: RFA-DA-23-053
Summary:

Women with opioid use disorder (OUD) are disproportionately impacted by physical, sexual, and psychological intimate partner violence and posttraumatic stress disorder (PTSD). Yet, treatment approaches that address all these conditions together in OUD treatment settings are lacking. To address this gap, this project will evaluate delivery of two evidence-based interventions to address PTSD (Present-Centered Therapy+ and Helping to Overcome PTSD through Empowerment) for women seeking OUD treatment who have experienced intimate partner violence. It will also determine if integrated treatment can help retain the women in medication treatment for OUD.

NOFO Title: HEAL Initiative: Development and Validation of Non-Rodent Mammalian Models of Pain (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-22-070
Summary:

Cerebral palsy (CP), the leading cause of childhood disabilities in the United States, refers to a group of neurological disorders that appear in infancy or early childhood and permanently affect body movement and muscle coordination. The experience of pain is one of the most common, poorly understood, and inadequately treated conditions in CP, impairing health and quality of life for both patients and caregivers. To understand why pain and motor dysfunction occur together, a model that accurately replicates both is needed. This project will validate an established, rabbit model of CP motor dysfunction for use in studying and developing effective treatments for CP-associated pain.

Developing and Testing Innovative Care Pathways for Screening and Treatment of OUD/PTSD in Jails Translation of Research to Practice for the Treatment of Opioid Addiction Optimizing the Quality, Reach, and Impact of Addiction Services NIDA UNIVERSITY OF ARKANSAS FOR MEDICAL SCIENCES ZIELINSKI, MELISSA JEAN (contact); ZALLER, NICKOLAS D Little Rock, AR 2023
NOFO Title: HEAL Initiative: Translating Research to Practice to End the Overdose Crisis (R61/R33 Clinical Trial Optional)
NOFO Number: RFA-DA-23-053
Summary:

Many people in jail have both opioid use disorder (OUD) and posttraumatic stress disorder (PTSD). Among people with OUD released from jail, only few engage in treatment and medication therapy once they are back in the community, and opioid overdose is a leading cause of death in this population. This project will test whether identifying and initiating treatment of PTSD in people receiving OUD treatment in jail can increase these individuals’ likelihood of starting and staying in medication treatment after release and thus reduce overdose risk.

NOFO Title: HEAL Initiative: Discovery of Biomarkers and Biomarker Signatures to Facilitate Clinical Trials for Pain Therapeutics (UG3/UH3 Clinical Trial Optional)
NOFO Number: RFA-NS-22-050
Summary:

Cataract surgery is commonly performed in older adults; however, some patients subsequently experience chronic eye pain that is difficult to treat. One promising approach that is effective in some, but not all, patients uses the patient's own serum (a component of blood) as eye drops. This project seeks to identify markers that can help predict which patients will respond to serum treatment and monitor their progress. Using advanced technology and data analysis to evaluate patient histories, questionnaires, and different genetic and other molecular characteristics in the eyes and serum it aims to identify potential markers that can then be tested in a clinical study.

Optimizing Patient-Centered Opioid Tapering with Mindfulness-Oriented Recovery Enhancement (MORE) Clinical Research in Pain Management Reducing Opioid-Related Harms to Treat Chronic Pain (IMPOWR and MIRHIQL) NIDA UNIVERSITY OF UTAH GARLAND, ERIC LEE (contact); COOPERMAN, NINA Salt Lake City, UT 2023
NOFO Title: HEAL Initiative: Multilevel Interventions to Reduce Harm and Improve Quality of Life for Patients on Long Term Opioid Therapy (MIRHIQL) (R01 Clinical Trial Required)
NOFO Number: RFA-DA-23-041
Summary:

Decreasing opioid dosing faster than advised by clinical recommendations often leaves chronic pain unaddressed and may increase the risk of overdose and suicide compared to continuing long-term opioid treatment. This project will compare a patient-centered tapering protocol with or without MORE in primary care offices in New Jersey and Utah. The MORE approach integrates training in mindfulness, reappraisal, and savoring to alter behavior away from valuation of drug rewards and toward natural rewards. This research will also identify practices to use MORE in primary care settings.

NOFO Title: Notice of Special Interest (NOSI): HEAL Initiative: Biospecimen Collection in Pregnancy
NOFO Number: NOT-DA-23-005
Summary:

Opioid use during pregnancy is associated with adverse outcomes for pregnant individuals and offspring. The mechanisms through which these outcomes arise and the consequences of prenatal opioid exposure on child health and development remain largely unexplored. The HEALthy Brain and Child Development (HBCD) Study is a nationwide longitudinal prospective study of early child development that will assess a broad spectrum of biological, behavioral, social, and health factors among 7,500 pregnant women and their children from pregnancy to mid-childhood. This supplement will expand the biospecimen collection of the HBCD protocol at the University of North Carolina at Chapel Hill to include delivery specimens (placenta, cord tissue, and cord blood). This will provide an unprecedented resource-generating opportunity for the larger scientific community to comprehensively evaluate mechanisms that mediate the connection between substance use during pregnancy and adverse neonatal, infant, and/or maternal health outcomes and inform innovative preventive strategies.
