COVID-19 vaccination and HIV transmission among persons who inject drugs during the first two years of the COVID-19 pandemic in New York City.

BACKGROUND: To examine COVID-19 vaccination and HIV transmission among persons who inject drugs (PWID) during the COVID-19 pandemic (2020-2022) in New York City (NYC). METHODS: Two hundred and seventy five PWID were recruited from October 2021 to September 2022. A structured questionnaire was used to measure demographics, drug use behaviors, overdose experiences, substance use treatment history, COVID-19 infection, vaccination, and attitudes. Serum samples were collected for HIV, HCV, and SARS-CoV-2 (COVID-19) antibody testing. RESULTS: Participants were: 71% male, the mean age was 49 (SD 11), 81% reported at least one COVID-19 immunization, 76% were fully vaccinated and 64% of the unvaccinated had antibodies for COVID-19. Self-reported injection risk behaviors were very low. HIV seroprevalence was 7%. Eighty-nine percent of the HIV seropositive respondents reported knowing they were HIV seropositive and being on antiretroviral therapy prior to the COVID-19 pandemic. There were two likely seroconversions in 518.83 person-years at risk from the March 2020 start of the pandemic to the times of interviews, for an estimated incidence rate of 0.39/100 person-years, 95% Poisson CI 0.05-1.39/100 person-years. CONCLUSIONS: There is concern that the COVID-19 pandemic disruptions to HIV prevention services and the psychological stress of the pandemic may lead to increased risk behavior and increased HIV transmission. These data indicate adaptive/resilient behaviors in both obtaining COVID-19 vaccination and maintaining a low rate of HIV transmission among this sample of PWID during the first two years of the COVID-19 pandemic in NYC.

Intersecting substance use treatment and harm reduction services: exploring the characteristics and service needs of a community-based sample of people who use drugs.

BACKGROUND: Substance use treatment and harm reduction services are essential components of comprehensive strategies for reducing the harms of drug use and overdose. However, these services have been historically siloed, and there is a need to better understand how programs that serve people who use drugs (PWUD) are integrating these services. In this study, we compared treatment and harm reduction services offered by a multistate sample of substance use service providers and assessed how well they align with characteristics and needs of clients they serve early in the COVID-19 pandemic. METHODS: We recruited a convenience sample of programs that deliver harm reduction and/or treatment services in ten US states. Program directors participated in a survey assessing the services offered at their program. We also recruited clients of these programs to participate in a survey assessing a range of sociodemographic and health characteristics, substance use behaviors, and health service utilization. We then cross-compared client characteristics and behaviors relative to services being offered through these programs. RESULTS: We collected and analyzed data from 511 clients attending 18 programs that we classified as either offering treatment with medications for opioid use disorder (MOUD) (N = 6), syringe service programs (SSP) (N = 8), or offering both MOUD and SSP (N = 4). All programs delivered a range of treatment and harm reduction services, with MOUD & SSP programs delivering the greatest breadth of services. There were discrepancies between services provided and characteristics and behaviors reported by clients: 80% of clients of programs that offered MOUD without SSP actively used drugs and 50% injected drugs; 40% of clients of programs that offered SSP without MOUD sought drug treatment services. Approximately half of clients were unemployed and unstably housed, but few programs offered direct social services. CONCLUSIONS: In many ways, existing programs are not meeting the service needs of PWUD. Investing in innovative models that empower clients and integrate a range of accessible and flexible treatment, harm reduction and social services can pave the way for a more effective and equitable service system that considers the long-term health of PWUD.

Modeling HIV transmission among persons who inject drugs (PWID) at the "End of the HIV Epidemic" and during the COVID-19 pandemic.

BACKGROUND: We explore injecting risk and HIV incidence among PWID in New York City (NYC), from 2012 to 2019, when incidence was extremely low, <0.1/100 person-years at risk, and during disruption of prevention services due to the COVID-19 pandemic. METHODS: We developed an Agent-Based model (ABM) to simulate sharing injecting equipment and measure HIV incidence in NYC. The model was adapted from a previous ABM model developed to compare HIV transmission with "high" versus "low" dead space syringes. Data for applying the model to NYC during the period of very low HIV incidence was taken from the "Risk Factors" study, a long-running study of participants entering substance use treatment in NYC. Injecting risk behavior had not been eliminated in this population, with approximately 15 % reported recent syringe sharing. Data for possible transmission during COVID-19 disruption was taken from previous HIV outbreaks and early studies of the pandemic in NYC. RESULTS: The modeled incidence rates fell within the 95 % confidence bounds of all of the empirically observed incidence rates, without any additional calibration of the model. Potential COVID-19 disruptions increased the probability of an outbreak from 0.03 to 0.25. CONCLUSIONS: The primary factors in the very low HIV incidence were the extremely small numbers of PWID likely to transmit HIV and that most sharing occurs within small, relatively stable, mostly seroconcordant groups. Containing an HIV outbreak among PWID during a continuing pandemic would be quite difficult. Pre-pandemic levels of HIV prevention services should be restored as quickly as feasible.

HIV Care Continuum Services for People Who Inject Drugs in Kazakhstan During COVID-19: A Qualitative Study of Service Provider Perspectives.

INTRODUCTION: The coronavirus disease (COVID-19) pandemic and resulting lockdowns have disrupted health care service delivery globally. This includes disruptions in harm reduction and HIV service delivery for people who inject drugs (PWID), a population at high risk for not only COVID-19 but also poor HIV and drug-treatment access. However, little is known about these issues in Kazakhstan. We examined harm reduction provider experiences with delivering services and regulatory changes during the COVID-19 pandemic. METHODS: We conducted in-depth interviews with 24 nurses, social workers, and doctors serving both HIV-positive and HIV-negative PWID at 13 needle and syringe programs (NSPs) and 4 AIDS Centers (HIV treatments centers) in Kazakhstan from May to August 2020. Participants were asked how the COVID-19 pandemic had impacted their PWID clients' risks, their organizational environment, and the services offered to PWID over the prior 3-6 months. Thematic content analysis was used to elicit findings. FINDINGS: The COVID-19 pandemic considerably impacted NSP and AIDS Center operations. Participants perceived high risks of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection for themselves and their clients, as well as pandemic-related increases in substance use and HIV risks for clients. Organizations instituted several policy and regulatory changes to adapt to the pandemic, most notably tasking NSPs with delivering HIV medications; these changes necessitated new roles and responsibilities for many providers. Despite this stressful changing environment and increased service demands, participants still shared examples of persistence and resilience as they worked to meet client needs during these challenging times. DISCUSSION: NSPs in Kazakhstan are well-positioned to reach key populations with crucial information and flexible services during the COVID-19 pandemic. However, they need recognition as essential organizations and additional equipment and staff support to protect staff and clients, maintain pandemic-related regulatory changes, and address additional challenges such as overdose prevention among clients.

A qualitative study exploring the impact of the COVID-19 pandemic on People Who Inject Drugs (PWID) and drug service provision in the UK: PWID and service provider perspectives.

BACKGROUND: People Who Inject Drugs (PWID) are subject to distinct socio-structural inequalities that can expose them to high risks of COVID-19 transmission and related health and social complications. In response to COVID-19 mitigation strategies, these vulnerabilities are being experienced in the context of adapted drug treatment service provision, including reduced in-person support and increased regulatory flexibility in opioid substitution therapy (OST) guidelines. This study aimed to explore the longer-term impact of the pandemic on the health and wellbeing of PWID in the UK, including provider and client experiences of treatment changes. METHODS: Interviews were conducted with 19 PWID and 17 drug treatment providers between May and September 2021, recruited from drug and homelessness charities providing treatment services and healthcare in the UK. Data were analysed using reflexive thematic analysis. RESULTS: Most participants expressed ongoing fears of COVID-19 transmission, although socio-structural inequalities limited the contexts in which physical distancing could be practised. In addition, virus mitigation strategies altered the risk environment for PWID, resulting in ongoing physical (e.g. changing drug use patterns, including transitions to crack cocaine, benzodiazepine and pregabalin use) and socio-economic harms (e.g. limited opportunities for sex work engagement and income generation). Finally, whilst clients reported some favourable experiences from service adaptations prompted by COVID-19, including increased regulatory flexibility in OST guidelines, there was continued scepticism and caution among providers toward sustaining any treatment changes beyond the pandemic period. CONCLUSIONS: Whilst our findings emphasize the importance of accessible harm reduction measures attending to changing indices of drug-related harm during this period, there is a need for additional structural supports to ensure pre-existing disparities and harms impacting PWID are not exacerbated further by the conditions of the pandemic. In addition, any sustained policy and service delivery adaptations prompted by COVID-19 will require further attention if they are to be acceptable to both service users and providers.

The Second Heart Program-A multidisciplinary team supporting people who inject drugs with infective endocarditis: Protocol of a feasibility study.

INTRODUCTION: Infective endocarditis (IE) is a severe and highly prevalent infection among people who inject drugs (PWID). While short-term (30-day) outcomes are similar between PWID and non-PWID, the long-term outcomes among PWID after IE are poor, with 1-year mortality rates in excess of 25%. Novel clinical interventions are needed to address the unique needs of PWID with IE, including increasing access to substance use treatment and addressing structural barriers and social determinants of health. METHODS AND ANALYSIS: PWID with IE will be connected to a multidisciplinary team that will transition with them from hospital to the community. The six components of the Second Heart Team are: (1) peer support worker with lived experience, (2) systems navigator, (3) addiction medicine physician, (4) primary care physician, (5) infectious diseases specialist, (6) cardiovascular surgeon. A convergent mixed-methods study design will be used to test the feasibility of this intervention. We will concurrently collect quantitative and qualitative data and 'mix' at the interpretation stage of the study to answer our research questions. ETHICS AND DISSEMINATION: This study has been approved by the Hamilton Integrated Research Ethics Board (Project No. 7012). Results will be presented at national and international conferences and submitted for publication in a scientific journal.

The impact of COVID-19 restrictions on needle and syringe programme provision and coverage in England.

BACKGROUND: The restrictions introduced in response to COVID-19 present many challenges, particularly for vulnerable and marginalised populations. These include maintaining access to Needle and Syringe Programmes (NSPs) to reduce the harms associated with injecting drugs. NSPs effectiveness is coverage dependent, but lockdowns and social distancing limit NSP access and availability. The impact on NSP provision in England is explored using enhanced monitoring data. METHOD: Data collected through an established comprehensive regional monitoring system from five four-week periods, centred on the implementation of restrictions in the UK in mid-March 2020, are examined. Weekly averages are compared to allow for public holidays and weekly variation in activity. RESULTS: The restrictions resulted in the number of NSP clients decreasing by 36%, visits by 36%, and needles distributed by 29%. NSP coverage for those injecting psychoactive drugs halved, declining from 14 needles per-week during the 4-weeks to 15th March 2020 to 7 needles per-week by mid-April, and coverage has remained at this level since then. CONCLUSIONS: Though it is currently unclear if there has been a decline in injecting, the decline in NSP coverage is so marked that it almost certainly reflects decreased utilisation among those in need, indicating increased equipment reuse and risk.
