Factors Associated with HIV Testing Among People Who Inject Drugs: Findings from a Multistate Study at the Start of the COVID-19 Pandemic.

Few studies have examined HIV testing among people who inject drugs (PWID) during the COVID-19 pandemic. This study examines factors associated with PWID who have been recently (past six months) tested for HIV during the COVID-19 pandemic. PWID were recruited between August 2020 and January 2021 from 22 drug treatment and harm reduction programs in nine states and the District of Columbia. We used logistic regression to identify correlates of recent HIV testing among PWID (n = 289). Most (52.9%) PWID reported having been recently tested for HIV. Factors associated with recent HIV testing included: having attended college [adjusted odds ratio (aOR) 2.32, 95% confidence interval (95% CI) 1.32-4.10], weekly hunger (aOR 2.08, 95% CI 1.20-3.60), crystal methamphetamine injection (aOR 2.04, 95% CI 1.05-3.97), and non-metropolitan residence (aOR 0.33, 95% CI 0.13, 0.88). Findings suggest HIV testing initiatives should be expanded during times of crisis, such as global pandemics.

Factors associated with receptive injection equipment sharing among people who inject drugs: findings from a multistate study at the start of the COVID-19 pandemic.

BACKGROUND: Receptive injection equipment sharing (i.e., injecting with syringes, cookers, rinse water previously used by another person) plays a central role in the transmission of infectious diseases (e.g., HIV, viral hepatitis) among people who inject drugs. Better understanding these behaviors in the context of COVID-19 may afford insights about potential intervention opportunities in future health crises. OBJECTIVE: This study examines factors associated with receptive injection equipment sharing among people who inject drugs in the context of COVID-19. METHODS: From August 2020 to January 2021, people who inject drugs were recruited from 22 substance use disorder treatment programs and harm reduction service providers in nine states and the District of Columbia to complete a survey that ascertained how the COVID-19 pandemic affected substance use behaviors. We used logistic regression to identify factors associated with people who inject drugs having recently engaged in receptive injection equipment sharing. RESULTS: One in four people who inject drugs in our sample reported having engaged in receptive injection equipment sharing in the past month. Factors associated with greater odds of receptive injection equipment sharing included: having a high school education or equivalent (adjusted odds ratio [aOR] = 2.14, 95% confidence interval [95% CI] 1.24, 3.69), experiencing hunger at least weekly (aOR = 1.89, 95% CI 1.01, 3.56), and number of drugs injected (aOR = 1.15, 95% CI 1.02, 1.30). Older age (aOR = 0.97, 95% CI 0.94, 1.00) and living in a non-metropolitan area (aOR = 0.43, 95% CI 0.18, 1.02) were marginally associated with decreased odds of receptive injection equipment sharing. CONCLUSIONS: Receptive injection equipment sharing was relatively common among our sample during the early months of the COVID-19 pandemic. Our findings contribute to existing literature that examines receptive injection equipment sharing by demonstrating that this behavior was associated with factors identified in similar research that occurred before COVID. Eliminating high-risk injection practices among people who inject drugs requires investments in low-threshold and evidence-based services that ensure persons have access to sterile injection equipment.

Increased solitary drug use during COVID-19: An unintended consequence of social distancing.

BACKGROUND: During the COVID-19 pandemic, overdose rates substantially increased in the United States. One possible contributor to this phenomenon may be solitary drug use resulting from social distancing efforts to prevent COVID-19 transmission. METHODS: We surveyed 458 people who use drugs (PWUD) who were recruited from harm reduction and drug treatment providers located in nine states and the District of Columbia. We assessed if solitary drug use had increased since the start of COVID-19. Associations between increased solitary drug use and sociodemographic characteristics, drug use characteristics, and COVID-19 prevention behaviors were examined using multiple logistic regression. RESULTS: Half the sample identified as men (52.7%), White (49.7%), and single (49.3%). The average age was 43.2 (SD:11.8) years. Two-thirds (66.8%) recently injected drugs. 44% reported increased solitary drug use since COVID-19. Significant correlates of increased solitary drug use included being single (adjusted Odds Ratio [aOR]=1.99, 95% Confidence Interval [CI]: 1.33, 2.98), increasing drug use (aOR=2.74, 95% CI: 1.72, 4.37), using more in private locations (aOR=1.91, 95% CI: 1.34, 2.72), and social distancing behaviors (aOR=1.31, 95% CI: 1.11, 1.54). Experiencing homelessness (aOR=0.45, 95% CI: 0.31, 0.65) and identifying as a sexual minority (aOR=0.53, 95% CI: 0.31, 0.93) were associated with being less likely to increase solitary drug use. CONCLUSIONS: Solitary drug use increased during the COVID-19 pandemic. Increases in solitary drug use, in the context of a drug market increasingly permeated by fentanyl, indicates an urgent need for comprehensive harm reduction interventions to reduce overdose mortality.

A stakeholder-driven framework for measuring potential change in the health risks of people who inject drugs (PWID) during the COVID-19 pandemic.

BACKGROUND: People who inject drugs (PWID) have likely borne disproportionate health consequences of the COVID-19 pandemic. PWID experienced both interruptions and changes to drug supply and delivery modes of harm reduction, treatment, and other medical services, leading to potentially increased risks for HIV, hepatitis C virus (HCV), and overdose. Given surveillance and research disruptions, proximal, indirect indicators of infectious diseases and overdose should be developed for timely measurement of health effects of the pandemic on PWID. METHODS: We used group concept mapping and a systems thinking approach to produce an expert stakeholder-generated, multi-level framework for monitoring changes in PWID health outcomes potentially attributable to COVID-19 in the U.S. This socio-ecological measurement framework elucidates proximal and distal contributors to infectious disease and overdose outcomes, many of which can be measured using existing data sources. RESULTS: The framework includes multi-level components including policy considerations, drug supply/distribution systems, the service delivery landscape, network factors, and individual characteristics such as mental and general health status and service utilization. These components are generally mediated by substance use and sexual behavioral factors to cause changes in incidence of HIV, HCV, sexually transmitted infections, wound/skin infections, and overdose. CONCLUSION: This measurement framework is intended to increase the quality and timeliness of research on the impacts of COVID-19 in the context of the current pandemic and future crises. Next steps include a ranking process to narrow the drivers of change in health risks to a concise set of indicators that adequately represent framework components, can be written as measurable indicators, and are quantifiable using existing data sources, as well as a publicly available web-based platform for summary data contributions.

Evaluating the impact of naloxone dispensation at public health vending machines in Clark County, Nevada.

INTRODUCTION: Implementing public health vending machines (PHVMs) is an evidence-based strategy for mitigating substance use-associated morbidity and mortality via the dispensation of essential supplies to people who use drugs, including overdose prevention resources. PHVMs have been implemented throughout the world; however, their implementation in the United States (US) is a recent phenomenon. In 2017, Trac-B Exchange (a syringe services program in Clark County, Nevada) installed three PHVMs. In 2019, naloxone dispensation was launched at PHVMs in Clark County. The purpose of this research is to examine the extent to which naloxone dispensation at PHVMs was associated with changes in opioid-involved overdose fatalities. METHODS: Monthly counts of opioid-involved overdose fatalities among Clark County residents that occurred from January 2015 to December 2020 were used to build an autoregressive integrated moving averages (ARIMA) model to measure the impact of naloxone dispensation at PHVMs. We forecasted the number of expected opioid-involved overdose fatalities had naloxone dispensation at PHVMs not occurred and compared to observed monthly counts. Interrupted time series analyses (ITSA) were used to evaluate the step (i.e. the immediate impact of naloxone dispensation at PHVMs on opioid-involved overdose fatalities) and slope change (i.e. changes in trend and directionality of monthly counts of opioid-involved overdose fatalities following naloxone dispensation at PHVMs). RESULTS: During the 12-months immediately following naloxone dispensation at PHVMs, our model forecasted 270 opioid-involved overdose fatalities, but death certificate data indicated only 229 occurred, suggesting an aversion of 41 deaths. ITSA identified a significant negative step change in opioid-involved overdose fatalities at the time naloxone dispensation at PHVMs was launched (B = -8.52, p = .0022) and a significant increasing slope change (B = 1.01, p<.0001). Forecasts that extended into the COVID-19 pandemic suggested worsening trends in overdose fatalities. CONCLUSION: Naloxone dispensation at PHVMs was associated with immediate reductions in opioid-involved overdose fatalities. Key MessagesNaloxone dispensation at PHVMs was associated with immediate reductions in opioid-involved overdose fatalities.Communities should consider implementing public health vending machines in efforts to prevent opioid-involved overdose fatalities.The COVID-19 pandemic worsened the overdose crisis.

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.

Exploring the impact of the COVID-19 pandemic on syringe services programs in rural Kentucky.

BACKGROUND: The coronavirus pandemic (COVID-19) exacerbated risks for adverse health consequences among people who inject drugs by reducing access to sterile injection equipment, HIV testing, and syringe services programs (SSPs). Several decades of research demonstrate the public health benefits of SSP implementation; however, existing evidence primarily reflects studies conducted in metropolitan areas and before the COVID-19 pandemic. OBJECTIVES: We aim to explore how the COVID-19 pandemic affected SSP operations in rural Kentucky counties. METHODS: In late 2020, we conducted eighteen in-depth, semi-structured interviews with persons (10 women, 8 men) involved in SSP implementation in rural Kentucky counties. The interview guide broadly explored the barriers and facilitators to SSP implementation in rural communities; participants were also asked to describe how COVID-19 affected SSP operations. RESULTS: Participants emphasized the need to continue providing SSP-related services throughout the pandemic. COVID-19 mitigation strategies (e.g., masking, social distancing, pre-packing sterile injection equipment) limited relationship building between staff and clients and, more broadly, the pandemic adversely affected overall program expansion, momentum building, and coalition building. However, participants offered multiple examples of innovative solutions to the myriad of obstacles the pandemic presented. CONCLUSION: The COVID-19 pandemic impacted SSP operations throughout rural Kentucky. Despite challenges, participants reported that providing SSP services remained paramount. Diverse adaptative strategies were employed to ensure continuation of essential SSP services, demonstrating the commitment and ingenuity of program staff. Given that SSPs are essential for preventing adverse injection drug use-associated health consequences, further resources should be invested in SSP operations to ensure service delivery is not negatively affected by co-occurring crises.

Experiences with substance use disorder treatment during the COVID-19 pandemic: Findings from a multistate survey.

BACKGROUND: Drug overdoses surged during the COVID-19 pandemic, underscoring the need for expanded and accessible substance use disorder (SUD) treatment. Relatively little is known about the experiences of patients receiving treatment during the pandemic. METHODS: We worked with 21 harm reduction and drug treatment programs in nine states and the District of Columbia from August 2020 to January 2021. Programs distributed study recruitment cards to clients. Clients responded to the survey by calling a study hotline and providing a unique study identification number. Our survey included detailed questions about use of SUD treatment prior to and since the COVID-19 pandemic. We identified settings where individuals received treatment and, for those treated for opioid use disorder, we examined use of medications for opioid use disorder. Individuals also reported whether they had received telehealth treatment and pandemic related treatment changes (e.g., more take-home methadone). We calculated p-values for differences pre and since COVID-19. RESULTS: We interviewed 587 individuals of whom 316 (53.8%) were in drug treatment both before and during the COVID-19 pandemic. Individuals in treatment reported substantial reductions in in-person service use since the start of the pandemic, including a 27 percentage point reduction (p<.001) in group counseling sessions and 28 percentage point reduction in mutual aid group participation (p<.001). By contrast, individuals reported a 21 percentage point increase in receipt of overdose education (p<.001). Most people receiving medications for opioid use disorder reported taking methadone and had high continuity of treatment (86.1% received methadone pre-COVID and 87.1% since-COVID, p=.71). Almost all reported taking advantage of new policy changes such as counseling by video/phone, increased take-home medication, or fewer urine drug screens. Overall, respondents reported relatively high satisfaction with their treatment and with telehealth adaptations (e.g., 80.2% reported "I'm able to get all the treatment that I need"). CONCLUSIONS: Accommodations to treatment made under the federal public health emergency appear to have sustained access to treatment in the early months of the pandemic. Since these changes are set to expire after the official public health emergency declaration, further action is needed to meet the ongoing need.

Practical implications of naloxone knowledge among suburban people who use opioids.

BACKGROUND: Naloxone distribution programs have been a cornerstone of the public health response to the overdose crisis in the USA. Yet people who use opioids (PWUO) continue to face a number of barriers accessing naloxone, including not knowing where it is available. METHODS: We used data from 173 PWUO from Anne Arundel County, Maryland, which is located between Baltimore City and Washington, DC. We assessed the prevalence of recently (past 6 months) receiving naloxone and currently having naloxone, the type(s) of the naloxone kits received, and the perceived ease/difficultly of accessing naloxone. We also assessed participants knowledge of where naloxone was available in the community. RESULTS: One third (35.7%) of participants had recently received naloxone. Most who had received naloxone received two doses (72.1%), nasal naloxone (86.9%), and education about naloxone use (72.1%). Most currently had naloxone in their possession (either on their person or at home; 78.7%). One third (34.4%) believed naloxone was difficult to obtain in their community. Only half (56.7%) knew of multiple locations where they could get naloxone. The health department was the most commonly identified naloxone source (58.0%). Identifying multiple sources of naloxone was associated with being more likely to perceive that naloxone is easy to access. DISCUSSION: Our results suggest that additional public health efforts are needed to make PWUO aware of the range of sources of naloxone in their communities in order to ensure easy and continued naloxone access to PWUO.
