Funded Projects

Although medication-based treatment for opioid use disorder (OUD) can effectively reduce overdose risk and improve health outcomes, most people discontinue treatment too soon. Peer support specialists, who are individuals with direct experience with a substance use disorder, can offer social support to help individuals with OUD overcome barriers to treatment and recovery. This project will develop, deliver, and evaluate an innovative peer support specialist intervention to help individuals begin and stay in a treatment program. The research will focus on rural populations and underserved communities, using a dynamic modeling framework to prioritize at-risk communities for treatment offered through mobile health clinics.

Significant racial, ethnic, socioeconomic, and geographic disparities affect access to opioid use disorder (OUD) treatment and have thus contributed to the opioid overdose crisis. Patient navigator interventions after hospitalization can improve access to treatment, but challenges prevent full adoption of these strategies. These include lack of coordination across institutions, inadequate data sharing, workforce shortages, and lack of awareness, especially in resource-limited communities. This project aims to develop a hospital system-wide patient navigation protocol that can be scaled up to address OUD treatment linkage and continuity after hospitalization.

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.

People who work in harm reduction settings aiming to keep people with substance use disorders safe from overdose and other negative health outcomes are exposed to high rates of lifetime and occupational stress and trauma. Their work conditions can have adverse effects on patient care and also on their own well-being, such as unmet mental health needs, burnout, and relapse. This project will adapt the Stress First Aid intervention for harm reduction workers. The research will test the impact of this intervention on social support, burnout, secondary traumatic stress, use of mental health care, engagement, and turnover. The long-term goal of this work is to implement a sustainable and effective national occupational stress intervention for harm reduction workers to strengthen their important role in helping individuals get treatment and avoid overdose.

An increasing number of Americans use multiple drugs at the same time, and overdose deaths from stimulants have increased. However, there are no available treatments for stimulant use disorder. This project aims to develop new treatment (SBS-518) for cocaine use disorder. Previous research using animal models showed that SBS-518 decreases stimulant self-administration without being rewarding itself. The research will continue the development of SBS-518 toward testing in human research participants.

The sodium channel NaV1.8 is a promising target for the development of effective, non-addictive pain medications. Recent evidence from clinical studies indicates that medications that target NaV1.8 are effective at managing postoperative, neuropathic, and inflammatory pain, but with side effects and prohibitively high cost. This project will test the safety and compatibility in the body of an NaV1.8-targeted molecule, toward developing an effective, non-addictive, once daily oral medication for the treatment of acute postsurgical pain and chronic neuropathic. 

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.

Difficulty breathing is a hallmark symptom of an opioid-related overdose and can result in permanent brain injury or death within minutes. This project will develop a community-deployable Automated External Respiration System device that can restore and sustain breathing in people experiencing opioid-induced respiratory depression. The device stimulates the phrenic nerve in the chest that controls breathing until other medical interventions are available or the patient recovers. The research will develop and validate the automated external respiration system for testing in human research participants and ultimately aims to develop a system usable in a community setting.

Endometriosis is a gynecologic disorder characterized by severe pelvic pain, affecting 10% of reproductive aged women and adolescents worldwide. These individuals are at an increased risk for chronic opioid use, dependence, and overdose. Adolescents and young adults in particular are understudied in endometriosis research. This project will conduct a longitudinal study of adolescent endometriosis. The research will identify novel biomarkers and biological pathways involved in the transition of acute to chronic pain. The research aims to improve non-surgical endometriosis diagnosis, risk, and treatment. 

Current practices and culture in treatment programs for opioid use disorder, including treatment with methadone, may contribute to treatment interruption and relapse risk. This project will develop and test a staff-level intervention for opioid treatment programs to increase methadone treatment retention and decrease in-treatment overdose and patient- and staff-reported posttraumatic stress symptoms. The intervention includes components to address trauma in patients and staff as well as separate supervisory structures for counselors/case managers and medical providers.

Oregon ranks last in the United States for access to substance use services, having passed a novel ballot measure bringing unprecedented funding levels to expand services and decriminalize possession of personal amounts of substances. This project will develop and evaluate a strategy to inform development of the policy. Cross-sector participants (e.g., community service providers, law enforcement, advocates) will co-design protocols for linking and distributing substance use service data through reports, simulations, and dashboards. This research will test the usability of the developed products and their impact of DDS on service gaps, evidence-based decision-making, quality of evidence-based services, service recipient outcomes, and cross-sector collaboration. The research will also help state decision makers implement strategies for other substance use policies.

The International Classification of Diseases 10th revision codes are insufficient to accurately identify individuals who use opioids and stimulants together. This project will search already collected electronic health record data using a computer program to identify people with polysubstance use and determine what health care they receive. The research will improve understanding of polysubstance use in a region of Los Angeles, California, with very high rates of overdoses involving fentanyl and stimulants.
