Correlates of Rural Naloxone Possession Among People Who Use Drugs
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 …
Modeling the impact of changing drug markets and structural determinants on HCV and/or HIV transmission among people who inject drugs in the United States
Associations of stigma, loneliness, and treatment self-regulation with HIV medication adherence among individuals with substance use disorder using a mobile health application
Introduction Medication adherence contributes to poor HIV outcomes, especially among people with HIV and Substance use disorder (SUD). Mobile health applications have been leveraged to improve behavioral health outcomes among this population. Our cross-sectional study examined the relationship between medication adherence with factors such as treatment self-regulation, isolation, and internalized stigma, among people with HIV and SUD using the Ad…
Medicaid Policy and Hepatitis C Treatment Among Rural People Who Use Drugs
BACKGROUND: Restrictive Medicaid policies regarding hepatitis C virus (HCV) treatment may exacerbate rural health care disparities for people who use drugs (PWUD). We assessed associations between Medicaid restrictions and HCV treatment among rural PWUD. METHODS: We compiled state-specific Medicaid treatment policies across 8 US rural sites in 10 states and merged these with participant survey data. We hypothesized that local restrictions regardi…
Travel history among persons infected with Sars-CoV-2 variants of concern in the United States, December 2020—February 2021
The first three SARS-CoV-2 phylogenetic lineages classified as variants of concern (VOCs) in the United States (U.S.) from December 15, 2020 to February 28, 2021, Alpha (B.1.1.7), Beta (B.1.351), and Gamma (P.1) lineages, were initially detected internationally. This investigation examined available travel history of coronavirus disease 2019 (COVID-19) cases reported in the U.S. in whom laboratory testing showed one of these initial VOCs. Travel …
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
MHealth and social mediation
The social mediation role of mobile technology is typified by mHealth apps designed to connect individuals to others and support substance use disorder (SUD) recovery. In this study, we examined the use and utility of one such app designed to support people living with HIV (PLWH) and SUD. Drawing on Ling’s emphasis on reciprocity and micro-coordination in mobile telephony as a social mediation technology, we gathered digital trace data from app l…
Performance of existing and novel surveillance case definitions for Covid-19 in household contacts of PCR-confirmed Covid-19
Existing COVID-19 case definitions appropriately screened in household contacts with COVID-19. Novel symptom combinations incorporating taste or smell dysfunction as a primary component improved accuracy. Case definitions tailored for children versus adults should be further explored
Potential Influences of the Covid-19 Pandemic on Drug Use and HIV Care Among People Living with HIV and Substance Use Disorders
“Service with open arms”
Effect of Patient Navigation on Transitions of HIV Care After Release from Prison
Avoidance, meaning and grief
Although the introduction of antiretroviral therapy has rendered HIV a chronic illness, inconsistent engagement in HIV care by key populations limits its public health impact. Poor engagement in care is especially prevalent among vulnerable populations with mental health and substance use disorders. Beyond structural and health system considerations, psychosocial factors may present challenges to sustained engagement. We conducted a qualitative s…
Implementing a Standardized Social Networks Testing Strategy in a Low HIV Prevalence Jurisdiction
Alternative HIV testing strategies are needed to engage individuals not reached by traditional clinical or non-clinical testing programs. A social networks recruitment strategy, in which people at risk for or living with HIV are enlisted and trained by community-based agencies to recruit individuals from their social, sexual, or drug-using networks for HIV testing, demonstrates higher positivity rates compared to other non-clinical recruitment st…
Re-entry experiences of Black men living with HIV/Aids after release from prison
The continuum of hepatitis C care for criminal justice involved adults in the DAA era
BACKGROUND: Incarcerated populations are disproportionately burdened by hepatitis C virus (HCV) infection. The introduction of highly-effective, direct-acting antiviral (DAA) treatment has potential to substantially reduce the burden of liver disease in this population, but accurate information about access to and utilization of this treatment is currently limited. The goals of this study were to characterize receipt of HCV care and treatment ser…
Manifestations of HIV stigma and their impact on retention in care for people transitioning from prisons to communities
BACKGROUND: While most people living with HIV who are incarcerated in United States receive appropriate HIV care while they are in prison, interruptions in antiretroviral therapy and virologic failure are extremely common after they are released. The purpose of this study was to describe whether and how HIV stigma influences continuity of care for people living with HIV while they transition from prison to community settings. METHODS: We conducte…
