Correlates of Rural Naloxone Possession Among People Who Use Drugs
Building standards of psychedelic care
Associations of hepatitis C virus (HCV) antibody positivity with opioid, stimulant, and polysubstance injection among people who inject drugs (PWID) in rural U.S. communities
HCV antibody positivity, indicating prior exposure, was highest among those who had recently injected opioids, alone or with stimulants. Additional nucleic acid testing is necessary to confirm active infection. More research is needed to determine the underlying causes of HCV antibody positivity by injection use
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 …
Oregon’s Emerging Psilocybin Services Workforce
New legal frameworks for supervised psychedelic services are emerging, with Oregon and Colorado implementing programs to train and license psilocybin facilitators. This study describes Oregon's early psilocybin facilitator workforce and assesses state-approved training programs. The Open Psychedelic Evaluation Nexus (OPEN) reviewed Oregon Health Authority-approved training programs and surveyed facilitators who had completed or were enrolled in t…
Personal Psychedelic Experience as a Training Qualification for Facilitators
Emerging legal frameworks in Oregon and Colorado license facilitators to support adults receiving psychedelic services. The current legal frameworks are silent regarding facilitators' personal experience with psychedelics. An e-Delphi process recruited 36 experts with at least 5 years' experience facilitating psilocybin experiences in ceremonial settings, indigenous practices, or clinical trials. Respondents completed in-depth, semi-structured qu…
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…
Correlates of Recent HIV Testing Among People Who Inject Drugs in Rural Areas
Stigma as a barrier to integrated substance use and HIV care in Vietnam
Integration of substance use disorder (SUD) treatment and HIV care can increase antiretroviral therapy coverage among people with opioid use disorder (OUD). However, implementation of integrated treatment models remains limited. Stigma towards people with OUD poses a barrier to initiation of, and adherence to, HIV treatment. We sought to understand the extent of stigma towards SUD and HIV among people with OUD in Vietnam, and the effect of stigma…

A hepatitis C elimination model in healthcare for the homeless organization
Experimental (Re)structuring
Amid the growth of addiction medicine randomized controlled trials (RCTs), scholars have begun examining participants' study experiences, highlighting facilitators and barriers to enrollment. However, this work can overlook the interplay between trial participation and social-structural dimensions among people with substance use disorders linked to the social nature of use, socioeconomic marginalization, and time demands of substance procurement …
Reducing overdose after release from incarceration (Roar)
HIV care continuum characteristics among people with opioid use disorder and HIV in Vietnam
While fewer than 90% of participants had received ART, 90% of those on ART had achieved HIV viral suppression at baseline, suggesting that interventions to improve uptake of ART in Vietnam are essential for achieving UNAIDS 90-90-90 goals in people who use heroin in Vietnam. Social determinants of health associated with ART and HIV viral suppression suggest that social support may be a key to facilitating both of these steps in the HIV care conti…
Effects of Naltrexone on Large-Scale Network Interactions in Methamphetamine Use Disorder
Naltrexone attenuates craving, and the subjective effects of methamphetamine and extended-release naltrexone (XR-NTX) reduces functional connectivity between regions of the striatum and limbic cortex. Naltrexone modulates neural activity at dopaminergic synapses; however, it is unclear whether naltrexone has an effect on large-scale brain networks. Functional networks interact to coordinate behavior, and as substance-use disorders are associated …
Emotional Communication in HIV Care
Which Clinician Questions Elicit Accurate Disclosure of Antiretroviral Non-adherence When Talking to Patients
Provider–Patient Communication About Adherence to Anti-retroviral Regimens Differs by Patient Race and Ethnicity
Implementing Rapid HIV Testing With or Without Risk-Reduction Counseling in Drug Treatment Centers
Objectives. We examined the effectiveness of risk reduction counseling and the role of on-site HIV testing in drug treatment. Methods. Between January and May 2009, we randomized 1281 HIV-negative (or status unknown) adults who reported no past-year HIV testing to (1) referral for off-site HIV testing, (2) HIV risk-reduction counseling with on-site rapid HIV testing, or (3) verbal information about testing only with on-site rapid HIV testing. Res…
Race, Relationships, and Trust in Providers among Black Patients with HIV/Aids
A trustful patient-provider relationship is a strong predictor of positive outcomes, including treatment adherence and viral suppression, among patients with HIV/AIDS. Understanding factors that inform this relationship is especially relevant for Black patients, who bear a disproportionate burden of HIV morbidity and mortality, and may face challenges associated with seeing providers of a racial/ethnic background that is different from their own.…

Measuring Medication
BACKGROUND: Medication measurement is crucial in assessing quality for chronic conditions yet agreement of alternate data sources remains uncertain. OBJECTIVES: To evaluate medication agreement between interviews, medical records, and pharmacy data; to assess data source contribution to attributing medication exposure; and to describe the impact of combining data sources on models that predict medication use. RESEARCH DESIGN: Prospective cohort s…
Racial and Gender Disparities in Receipt of Highly Active Antiretroviral Therapy Persist in a Multistate Sample of HIV Patients in 2001
BACKGROUND: National data from the mid-1990s demonstrated that many eligible patients did not receive highly active antiretroviral therapy (HAART) and that racial and gender disparities existed in HAART receipt. We examined whether demographic disparities in the use of HAART persist in 2001 and if outpatient care is associated with HAART utilization. METHODS: Demographic, clinical, and pharmacy utilization data were collected from 10 US HIV prima…
Hospital and Outpatient Health Services Utilization Among HIV-Infected Adults in Care 2000–2002
BACKGROUND: Rapid changes in HIV epidemiology and antiretroviral therapy may have resulted in recent changes in patterns of healthcare utilization. OBJECTIVE: The objective of this study was to examine sociodemographic and clinical correlates of inpatient and outpatient HIV-related health service utilization in a multistate sample of patients with HIV. DESIGN: Demographic, clinical, and resource utilization data were collected from medical record…
The impact of illicit drug use and substance abuse treatment on adherence to Haart
High levels of adherence to highly active antiretroviral therapy (HAART) are essential for virologic suppression and longer survival in patients with HIV. We examined the effects of substance abuse treatment, current versus former substance use, and hazardous/binge drinking on adherence to HAART. During 2003, 659 HIV patients on HAART in primary care were interviewed. Adherence was defined as > or =95% adherence to all antiretroviral medications.…
The Impact of Integrated HIV Care on Patient Health Outcomes
BACKGROUND: Control of viral replication through combination antiretroviral therapy (cART) improves patient health outcomes. Yet many HIV-infected patients have comorbidities that pose social and clinical barriers to achieving viral suppression. Integration of subspecialty services into HIV primary care may overcome such barriers. OBJECTIVE: To evaluate effect of integrated HIV care (IHC) on suppression of HIV replication. RESEARCH DESIGN: A retr…

Closing the Gap
BACKGROUND: Combination antiretroviral therapy (ART) has significantly increased survival among HIV-positive adults in the United States (U.S.) and Canada, but gains in life expectancy for this region have not been well characterized. We aim to estimate temporal changes in life expectancy among HIV-positive adults on ART from 2000-2007 in the U.S. and Canada. METHODS: Participants were from the North American AIDS Cohort Collaboration on Research…
The impact of depressive symptoms on patient–provider communication in HIV care
Persons with HIV who develop depression have worse medical adherence and outcomes. Poor patient-provider communication may play a role in these outcomes. This cross-sectional study evaluated the influence of patient depression on the quality of patient-provider communication. Patient-provider visits (n=406) at four HIV care sites were audio-recorded and coded with the Roter Interaction Analysis System (RIAS). Negative binomial and linear regressi…
