Canada has long contended with harms arising from injection drug use. In response to epidemics of HIV infection and overdose in Vancouver in the mid-1990s, a range of actors advocated for the creation of supervised injection facilities (SIFs), and after several unsanctioned SIFs operated briefly and closed, Canada’s first sanctioned SIF opened in 2003. However, while a large body of evidence highlights the successes of this SIF in reducing the health and social harms associated with injection drug use, extraordinary efforts were needed to preserve it, and continued activism by local people who inject drugs (PWID) and healthcare providers was needed to promote further innovation and address gaps in SIF service delivery. A growing acceptance of SIFs and increasing concern about overdose have since prompted a rapid escalation in efforts to establish SIFs in cities across Canada. While much progress has been made in that regard, there is a pressing need to create a more enabling environment for SIFs through amendment of federal legislation. Further innovation in SIF programming should also be encouraged through the creation of SIFs that accommodate assisted injecting, the inhalation of drugs. As well, peer-run, mobile, and hospital-based SIFs also constitute next steps needed to optimize the impact of this form of harm reduction intervention.

Needle-syringe programs (NSP) have been effective in reducing HIV and hepatitis C (HCV) infection among people who inject drugs (PWID). Achieving sustainable reductions in these blood-borne infections requires addressing structural factors so PWID can legally access NSP services. Systematic literature searches collected information on NSP coverage and changes in HIV or HCV infection prevalence or incidence at the population level. Included studies had to document biomarkers (HIV or HCV) coupled with structural-level NSP, defined by a minimum 50 % coverage of PWID and distribution of 10 or more needles/syringe per PWID per year. Fifteen studies reported structural-level NSP and changes in HIV or HCV infection prevalence/incidence. Nine reported decreases in HIV prevalence, six in HCV infection prevalence, and three reported decreases in HIV incidence. The results support NSP as a structural-level intervention to reduce population-level infection and implementation of NSP for prevention and treatment of HIV and HCV infection.

An HIV outbreak in rural Indiana provides a cautionary tale. An aggressive, multipronged strategy is needed to prevent similar outbreaks, and it requires permanently lifting the ban on using federal funds to support needle-exchange programs. Many observers were surprised when Indiana Governor Mike Pence issued an executive order on March 26, 2015, declaring a public health emergency after a rapidly escalating outbreak of human immunodeficiency virus (HIV) was identified in Scott County, a rural region on the Kentucky border. 1 Others, however, had seen it coming. Over the years, a growing number of young people in Scott County — like those in surrounding counties and states — had begun abusing opiates such as oxymorphone, an opioid analgesic prescribed by local medical providers, until a more tamper-resistant formulation and policy reform began limiting its abuse.

Background In 2018–2019, Canada introduced a Prison Needle Exchange Program (PNEP) across nine federal facilities to mitigate the harms associated with drug injection among incarcerated people. However, program uptake has been limited. We explored the barriers and facilitators to improving PNEP services among key stakeholders in prison. Methods Stakeholders in nine federal prisons with active PNEP participated in focus groups using nominal group technique to achieve rapid consensus. Responses were generated, rank-ordered, and prioritized by each stakeholder group (correctional officers, healthcare workers, and people in prison). We identified the highest-ranking responses to questions about barriers and solutions to PNEP uptake and described them using the five levels of the Socioecological Model: individual, interpersonal, organizational, system, and structural/policy. Results Between September 2023 and February 2024, 34 focus groups were conducted with 215 participants ( n  = 51 correctional officers (24%); n  = 67 healthcare workers (31%); n  = 97 people in prison (45%)). Key barriers identified were lack of confidentiality and privacy across all levels and fear of repercussions from drug use and fear of being targeted at the individual-interpersonal levels. Preferred solutions included comprehensive education across all levels, and establishment of supervised/safe injection sites and external program management, potentially involving peers, at the structural level. Conclusions Several multi-level modifiable barriers to improving PNEP uptake in Canadian federal prisons were shared among key stakeholders. Structural changes to PNEP delivery, including supervised/safe injecting sites and peer-led programs, were proposed as solution-driven enablers to increasing PNEP uptake among incarcerated people who inject drugs. These data will inform Canadian efforts to expand PNEP provision.

Background In Baltimore, MD, as in many cities throughout the USA, overdose rates are on the rise due to both the increase of prescription opioid abuse and that of fentanyl and other synthetic opioids in the drug market. Supervised injection facilities (SIFs) are a widely implemented public health intervention throughout the world, with 97 existing in 11 countries worldwide. Research has documented the public health, social, and economic benefits of SIFs, yet none exist in the USA. The purpose of this study is to model the health and financial costs and benefits of a hypothetical SIF in Baltimore. Methods We estimate the benefits by utilizing local health data and data on the impact of existing SIFs in models for six outcomes: prevented human immunodeficiency virus transmission, Hepatitis C virus transmission, skin and soft-tissue infection, overdose mortality, and overdose-related medical care and increased medication-assisted treatment for opioid dependence. Results We predict that for an annual cost of $1.8 million, a single SIF would generate $7.8 million in savings, preventing 3.7 HIV infections, 21 Hepatitis C infections, 374 days in the hospital for skin and soft-tissue infection, 5.9 overdose deaths, 108 overdose-related ambulance calls, 78 emergency room visits, and 27 hospitalizations, while bringing 121 additional people into treatment. Conclusions We conclude that a SIF would be both extremely cost-effective and a significant public health and economic benefit to Baltimore City.

We conducted a systematic review and meta-analysis of the impact of needle and syringe exchange programs (NSP) on both individual- and community-level needle-sharing behaviors and other HIV-related outcomes in low- and middle-income countries (LMIC). A search of five databases for peer-reviewed trial or quasi-experimental studies reported through July 2021 identified 42 interventions delivered in 35 studies, with a total of 56,751 participants meeting inclusion criteria. Random-effects meta-analysis showed a significant protective association between NSP exposure and needle-sharing behaviors at the individual-level (odds ratio [OR] = 0.25, 95% confidence interval [CI] = 0.16–0.39, 8 trials, n = 3947) and community-level (OR 0.39, CI 0.22–0.69, 12 trials, n = 6850), although with significant heterogeneity. When stratified by needle-sharing directionality, NSP exposure remained associated with reduced receptive sharing, but not distributive sharing. NSP exposure was also associated with reduced HIV incidence and increased HIV testing but there were no consistent associations with prevalence of bloodborne infections. Current evidence suggests positive impacts of NSPs in LMICs.

Amid an opioid epidemic and increasing HIV and hepatitis C virus (HCV) concerns, the Louisville Metro Department of Public Health and Wellness developed syringe exchange programming (SEP) to reduce HIV and HCV transmission, increase linkage to health care, and provide health education to clients in Louisville, Kentucky. We describe organizational, community, and policy factors contributing to SEP development. Approximately 8000 clients received SEP services from June 2015 to December 2016. Coalition building, timely advocacy, and media engagement are integral to successful SEP development and uptake.

To examine whether increasing investment in needle/syringe exchange programs (NSPs) in the US would be cost-effective for HIV prevention, we modeled HIV incidence in hypothetical cases with higher NSP syringe supply than current levels, and estimated number of infections averted, cost per infection averted, treatment costs saved, and financial return on investment. We modified Pinkerton’s model, which was an adaptation of Kaplan’s simplified needle circulation theory model, to compare different syringe supply levels, account for syringes from non-NSP sources, and reflect reduction in syringe sharing and contamination. With an annual $10 to $50 million funding increase, 194–816 HIV infections would be averted (cost per infection averted $51,601–$61,302). Contrasted with HIV treatment cost savings alone, the rate of financial return on investment would be 7.58–6.38. Main and sensitivity analyses strongly suggest that it would be cost-saving for the US to invest in syringe exchange expansion.

Objectives. We aimed to determine whether syringe exchange programs (SEPs) currently receive or anticipate pursuing federal funding and barriers to funding applications following the recent removal of the long-standing ban on using federal funds for SEPs. Methods. We conducted a telephone-administered cross-sectional survey of US SEPs. Descriptive statistics summarized responses; bivariate analyses examined differences in pursuing funding and experiencing barriers by program characteristics. Results. Of the 187 SEPs (92.1%) that responded, 90.9% were legally authorized. Three received federal funds and 116 intended to pursue federal funding. Perceived federal funding barriers were common and included availability and accessibility of funds, legal requirements such as written police support, resource capacity to apply and comply with funding regulations, local political and structural organization, and concern around altering program culture. Programs without legal authorization, health department affiliation, large distribution, or comprehensive planning reported more federal funding barriers. Conclusions. Policy implementation gaps appear to render federal support primarily symbolic. In practice, funding opportunities may not be available to all SEPs. Increased technical assistance and legal reform could improve access to federal funds, especially for SEPs with smaller capacity and tenuous local support.

Objectives. To estimate health outcomes of policies to mitigate the opioid epidemic. Methods. We used dynamic compartmental modeling of US adults, in various pain, opioid use, and opioid addiction health states, to project addiction-related deaths, life years, and quality-adjusted life years from 2016 to 2025 for 11 policy responses to the opioid epidemic. Results. Over 5 years, increasing naloxone availability, promoting needle exchange, expanding medication-assisted addiction treatment, and increasing psychosocial treatment increased life years and quality-adjusted life years and reduced deaths. Other policies reduced opioid prescription supply and related deaths but led some addicted prescription users to switch to heroin use, which increased heroin-related deaths. Over a longer horizon, some such policies may avert enough new addiction to outweigh the harms. No single policy is likely to substantially reduce deaths over 5 to 10 years. Conclusions. Policies focused on services for addicted people improve population health without harming any groups. Policies that reduce the prescription opioid supply may increase heroin use and reduce quality of life in the short term, but in the long term could generate positive health benefits. A portfolio of interventions will be needed for eventual mitigation.
