Patterns of Felt Stigma Among Rural-Dwelling People Who Use Drugs
BACKGROUND: Stigma is a barrier to help-seeking in rural-dwelling people who use drugs. However, little is known about whether stigma is experienced in patterned ways, and what characteristics are associated with these patterns. METHODS: = 3048). We used three-step latent class analysis to classify participants by patterns of felt substance use stigma, then used multinomial logistic regression to explore demographic, health, and substance-related…
“Fentanyl Is the Name of the Game”
In Washington State, the dynamic drug policy around fentanyl has not only transformed policing but also the ways people who use drugs make sense of their own practices. Drawing on in-depth interviews with 20 people who use both opioids and methamphetamine, this article shows how legislative changes associated with the changing “moral panic” from methamphetamine to fentanyl have affected how people conceptualize the health and legal risks associat…
High Prevalence of Unhealthy Alcohol Use Among Persons with HIV, Viral Non-suppression and Any Alcohol Use in Mbarara, Uganda
Unhealthy alcohol use is associated with HIV viral non-suppression. It is unclear how common unhealthy alcohol use is among non-suppressed persons with HIV (PWH) who drink alcohol. We conducted chart reviews to recruit PWH in Uganda with recent viral non-suppression for a study on the efficacy of gabapentin for promoting viral suppression among those with unhealthy alcohol use. Of the 288 PWH screened, 87% self-reported unhealthy alcohol use on t…
Impact of Social Drivers of Health, Self-Efficacy, and Substance Use on Covid-19 Preventative Behaviors Among Persons Who Inject Drugs with Hepatitis C
Greater SDoH difficulties and lower self-efficacy were associated with greater inability to practice COVID-19 personal protective behaviors. Interventions to meet SDoH-related challenges and increase self-efficacy could help encourage practice of personal protective behaviors and economically reduce disease burden during health crises

BACKGROUND AND AIMS: The development of comprehensive strategies to understand emerging trends in substance use is necessary to design effective prevention and harm reduction strategies for people who use drugs (PWUD). Dried blood spots (DBS) can be used as a non-conventional drug testing approach that meets Food and Drug Administration (FDA) accuracy and precision guidelines. DESIGN, SETTING, AND PARTICIPANTS: From July 2021 to July 2022, 1,559 …
Formative qualitative research to guide implementation of the Collaborative Care Model in a low-barrier HIV clinic
Integrated behavioral healthcare interventions have increased access to care for people with behavioral health conditions in primary care settings. However, they have not been widely implemented in low-barrier HIV care settings where undertreated behavioral health needs remain high. We conducted a formative qualitative evaluation, using in-depth interviews with purposively selected stakeholders (n = 13) and patients (n = 16), to identify anticipa…
Prevalence and correlates of multiple injections per injection episode among people who inject drugs in rural U.S. communities
Barriers to accessing medications for opioid use disorder among rural individuals
Access barriers vary by MOUD type for rural individuals with OUD. Compared to sublingual buprenorphine, methadone access was hindered more by transportation difficulties, while injectable long-acting buprenorphine was hindered more by affordability and finding a doctor or program. These barriers highlight the need to de-regulate and expand locations for methadone access and prescribing, and to improve affordability and prescriber uptake of newer …

Priorities for HIV and chronic pain research
The Global Task Force on Chronic Pain in HIV published seven research priorities in the field of HIV-associated chronic pain in 2019: (1) causes; (2) management; (3) treatment individualization and integration with addiction treatment; (4) mental and social health factors; (5) prevalence; (6) treatment cost effectiveness; and (7) prevention. The current study used a web-based survey to determine whether the research topics were aligned with the p…
Self-reported and measured adherence to hepatitis C direct-acting antiviral therapy and sustained virologic response among people who inject drugs
Post-traumatic stress disorder and risky opioid use among persons living with HIV and chronic pain
Persons with HIV (PWH) experience chronic pain and Post-Traumatic Stress Disorder (PTSD) at higher rates than the general population, and more often receive opioid medications to treat chronic pain. A known association exists between PTSD and substance use disorders, but less is known about the relationship between PTSD and risky opioid use among PWH taking prescribed opioid medications. In this observational study of PWH on long-term opioid medi…
The Global Task Force for Chronic Pain in People with HIV (PWH)
Chronic pain is a common comorbidity in people with HIV (PWH), with prevalence estimates of 25-85%. Research in this area is growing, but significant gaps remain. A Global Task Force of HIV experts was organized to brainstorm a scientific agenda and identify measurement domains critical to advancing research in this field. Experts were identified through literature searches and snowball sampling. Two online questionnaires were developed by Task F…
Pilot study of tolerability and safety of opioid receptor antagonists as novel therapies for chronic pain among persons living with HIV with past year heavy drinking
Pain is common and associated with substance use among persons with HIV (PWH), yet limited management strategies exist. We assessed the feasibility, tolerability, and safety of low-dose naltrexone and standard dose nalmefene to treat chronic pain among PWH with past-year heavy alcohol use in a randomized, double-blinded, 2-arm study (planned enrollment 8 per arm). Participants were recruited in St. Petersburg, Russia between May and October 2018 …
Substance use disorder treatment and technology access among people who use drugs in rural areas of the United States
PURPOSE: To evaluate how technology access affected substance use disorder (SUD) treatment prior to COVID-19 for people who use drugs in rural areas. METHODS: The Rural Opioid Initiative (January 2018-March 2020) was a cross-sectional study of people with prior 30-day injection drug or nonprescribed opioid use from rural areas of 10 states. Using multivariable mixed-effect regression models, we examined associations between participant technology…

Drug and alcohol use among people living with HIV in care in the United States by geographic region
Substance use in the U.S. varies by geographic region. Opioid prescribing practices and marijuana, heroin, and methamphetamine availability are evolving differently across regions. We examined self-reported substance use among people living with HIV (PLWH) in care at seven sites from 2017-2019 to understand current regional substance use patterns. We calculated the percentage and standardized percentage of PLWH reporting current drug use and at-r…
Predictors of pain-related functional impairment among people living with HIV on long-term opioid therapy
People living with HIV (PLWH) have high levels of functional impairment due to pain, also called pain interference. Long-term opioid therapy (LTOT) is commonly prescribed for chronic pain among PLWH. We sought to better understand the predictors of pain interference, measured with the Brief Pain Inventory Interference subscale (BPI-I), among PLWH with chronic pain on LTOT. Using a prospective cohort of PLWH on LTOT we developed a model to identif…
