"People knew they could come here to get help": an ethnographic study of assisted injection practices at a peer-run 'unsanctioned' supervised drug consumption room in a Canadian setting

The effect of Montreal's supervised consumption sites on injection-related infections among people who inject drugs: An interrupted time series

BACKGROUND

Between June and November 2017, four supervised consumption sites (SCS) began operating in Montreal, Quebec. Earlier studies on SCS focused on examining their effects on blood-borne viral infections and overdose mortality. Our objective was to examine the effect of Montreal's SCS on the incidence, health service use and outcomes of injection-related infections (IRI) in people who inject drugs.

METHODS

We used Quebec's provincial administrative health data to identify people who inject drugs in Montreal and calculated the incidence of IRI in this population between December 2014 and December 2019. We conducted a retrospective, population-based interrupted time series to estimate the effect of Montreal's four SCS on the monthly incidence rates of IRI-related hospitalizations, emergency department (ED) visits, physician visits, and mortality. We also examined the effects of SCS on average length of IRI-related hospitalizations and incidence of hospitalizations involving surgery.

RESULTS

The average age of Montreal's people who inject drugs was 41.84 years, and 66.41% were male. After the implementation of SCS, there was a positive level change in the incidence of hospitalizations (0.97; 95% confidence interval [CI]: 0.26, 1.68) for IRI. There was also a significant post-intervention decline in hospitalization trends (-0.05; 95% CI: -0.08, -0.02), with modest trend changes in ED visits (-0.02; 95% CI: -0.05, 0.02). However, post-intervention changes in level (0.72; 95% CI: -3.85, 5.29) and trend (0.06; 95% CI: -0.23, 0.34) for physician visits remained limited. SCS had no effect on the average length of hospitalizations, but there was a decreasing post-intervention trend in hospitalizations involving surgery (-0.03; 95% CI: -0.06, 0.00).

CONCLUSION

Following the opening of the SCS, there was a moderate decline in the rate of hospitalizations to treat IRI, but the impact of the sites on the rate of physician visits remained limited. These findings suggest that SCS may mitigate the incidence of more serious and complicated IRI over time.

Using nominal group technique with people who are incarcerated in Canadian federal prisons to identify barriers and solutions to improving Prison Needle Exchange Program uptake

BACKGROUND

Prison needle exchange programs (PNEPs) are a critical component for harm reduction in prisons. Little is known about the PNEP access barriers for people who are incarcerated, but the low uptake in the Canadian program highlights these constraints. We aimed to identify the barriers and potential solutions for increasing PNEP coverage in the nine Canadian federal prisons where they operate.

METHODS

Eighteen focus groups were conducted in nine prisons using nominal group technique (NGT) with two stakeholders: peer advocates and people who use or identified as potential users of the PNEP. NGT uses a round-robin technique followed by generating a list of barriers to PNEP enrolment within their prison. Participants then allocated votes to rank the highest priority barriers, followed by an identical process to generate solutions to address the top three barriers. Interview transcripts describing participant narratives during this process were de-identified and coded to generated themes. Barriers and solutions receiving >10 % of votes within respective participant groups, alongside associated narratives, are discussed more fully.

RESULTS

Fear of repercussions due to drug use, lack of confidentiality, and fear of being targeted and sanctioned by correctional authorities were perceived by both stakeholder groups as the top barriers inhibiting PNEP enrolment. Stigma (peer advocates) and the application process for the program (PNEP users) were also ranked as a priority. Proposed solutions included education and external oversight of PNEP (i.e., not via correctional officers) by both groups. Peer advocates regarded improving participant confidentiality and a supervised/safe injection site as potential enablers for program participation, while PNEP users identified wrap-around services as likely to improve access.

CONCLUSION

Barriers to increasing PNEP coverage in Canadian federal prisons proposed by participants highlight the importance of trust and perceived repercussions surrounding program participation. These barriers and proposed solutions highlight a need for changes in implementation to PNEP delivery if the potential health benefits of PNEPs are to be realised.

Overdose prevention centres as spaces of safety, trust and inclusion: A causal pathway based on a realist review

ISSUES

Overdose prevention centres (OPC) are non-residential spaces where people can use illicit drugs (that they have obtained elsewhere) in the presence of staff who can intervene to prevent and manage any overdoses that occur. Many reviews of OPCs exist but they do not explain how OPCs work.

APPROACH

We carried out a realist review, using the RAMESES reporting standards. We systematically searched for and then thematically analysed 391 documents that provide information on the contexts, mechanisms and outcomes of OPCs.

KEY FINDINGS

Our retroductive analysis identified a causal pathway that highlights the feeling of safety - and the immediate outcome of not dying - as conditions of possibility for the people who use OPCs to build trust and experience social inclusion. The combination of safety, trust and social inclusion that is triggered by OPCs can - depending on the contexts in which they operate - generate other positive outcomes, which may include less risky drug use practices, reductions in blood borne viruses and injection-related infections and wounds, and access to housing. These outcomes are contingent on relevant contexts, including political and legal environments, which differ for women and people from racialised minorities.

CONCLUSIONS

OPCs can enable people who live with structural violence and vulnerability to develop feelings of safety and trust that help them stay alive and to build longer term trajectories of social inclusion, with potential to improve other aspects of their health and living conditions.

"It's Like A Partnership": Exploring the Primary Care Experiences and Patient-Defined Goals of People Who Use Drugs

BACKGROUND

Primary care is an important yet underutilized resource in addressing the overdose crisis. Previous studies have identified important aspects of primary care for people who use drugs (PWUD) and have found patient involvement in healthcare decisions and goal-setting to be especially critical. However, there has been limited research describing the primary care goals of PWUD. In harm reduction settings, where it is imperative that PWUD set their own goals, this research gap becomes especially relevant.

OBJECTIVE

To explore how PWUD navigate primary care with a focus on understanding their primary care goals.

DESIGN

A qualitative study using semi-structured interviews.

PARTICIPANTS

PWUD currently engaged in primary care at the Respectful and Equitable Access to Comprehensive Healthcare (REACH) Program, a harm reduction-based primary care program in New York City.

APPROACH

Between June 2022 and August 2022, we conducted 17 semi-structured interviews. Informed by phenomenology, transcripts were coded using both inductive and deductive codes and themes were developed using thematic analysis approaches.

KEY RESULTS

Phenomenological analysis identified four core components that, together, created an experience that participants described as "a partnership" between patient and provider: (1) patient-provider collaboration around patient-defined healthcare goals; (2) support provided by harm reduction-based approaches to primary care anchored in incrementalism and flexibility; (3) care teams' ability to address healthcare system fragmentation; and (4) the creation of social connections through primary care. This holistic partnership fostered positive primary care experiences and supported participants' self-defined care goals, thereby facilitating meaningful care outcomes.

CONCLUSIONS

To best meet the primary care goals of PWUD, these findings underscore the importance of primary care providers and programs facilitating such partnerships through organizational-level support anchored in harm reduction. Future research should explore how these experiences in primary care affect patient health outcomes, ultimately shaping best practices in the provision of high-quality primary care for PWUD.

"Everybody is impacted. Everybody's hurting": Grief, loss and the emotional impacts of overdose on harm reduction workers

BACKGROUND

The emotional impacts of witnessing and responding to overdose and overdose-related deaths have been largely overlooked during the drug toxicity overdose crisis in North America. Scarce research has analyzed these impacts on the health and well-being of harm reduction workers, and the broader determinants of harm reduction work. Our study investigates the experiences and impacts of witnessing and responding to frequent and escalating rates of overdose on harm reduction workers in Toronto, Canada.

METHODS

Using semi-structured interviews, 11 harm reduction workers recruited from harm reduction programs with supervised consumption services in Toronto, Canada, explored experiences with and reactions to overdose in both their professional and personal lives. They also provided insights on supports necessary to help people cope with overdose-related loss. We used thematic analysis to develop an initial coding framework, subsequent iterations of codes and emergent themes.

RESULTS

Results revealed that harm reductions workers experienced physical, emotional, and social effects from overdose-related loss and grief. While some effects were due to the toll of overdose response and grief from overdose-related losses, they were exacerbated by the lack of political response to the scale of the drug toxicity overdose crisis and the broader socio-economic-political environment of chronic underfunding for harm reduction services. Harm reduction workers described the lack of appropriate workplace supports for trauma from repeated overdose response and overdose-related loss, alongside non-standard work arrangements that resulted in a lack of adequate compensation or access to benefits.

CONCLUSIONS

Our study highlights opportunities for organizational practices that better support harm reduction workers, including formal emotional supports and community-based supportive care services. Improvement to the socio-economic-political determinants of work such as adequate compensation and access to full benefit packages are also needed in the harm reduction sector for all workers.

Characterizing Use of Supervised Consumption Services among Street-involved Youth and Young Adults in the Context of an Overdose Crisis

In response to an increase in overdose deaths, there was a rapid scale-up of supervised consumption services (SCS), including federally sanctioned SCS and low-barrier SCS known as overdose prevention sites (OPS), in Vancouver, Canada, beginning in December 2016. However, little is known about the use of such services among adolescents and young adults (AYA) in this context. We therefore sought to characterize factors associated with the use of federally sanctioned SCS and OPS among street-involved AYA who inject drugs in Vancouver during an overdose crisis. From December 2016 to March 2020, data were collected from a prospective cohort of street-involved AYA aged 14 to 26 at baseline. Using multivariable generalized estimating equation analyses, we identified factors associated with recent use of federally sanctioned SCS and OPS, respectively. Among 298 AYA who inject drugs, 172 (57.8%) and 149 (50.0%) reported using federally sanctioned SCS and OPS during the study period, respectively. In multivariable analyses, public injecting, negative police interactions, and residing or spending time ≥ weekly in the Downtown Eastside neighborhood were all positively associated with the use of federally sanctioned SCS and OPS, respectively. Additionally, ≥ daily unregulated opioid use and residential eviction were positively associated with federally sanctioned SCS use, while requiring help injecting was inversely associated. Self-identified female or non-binary gender was also positively associated with OPS use (all p < 0.05). Both federally sanctioned SCS and OPS successfully engaged AYA at heightened risk of adverse health outcomes. However, the lack of accommodation of AYA who require manual assistance with injecting at federally sanctioned SCS may be inhibiting service engagement.

"Notice of major cleaning": A qualitative study of the negative impact of encampment sweeps on the ontological security of unhoused people who use drugs

BACKGROUND

Unhoused people who use drugs in the United States are at risk for a variety of negative health outcomes. As the crisis of houselessness continues to impact major urban areas, a wave of punitive policies has been enacted to remove visible unhoused people from public spaces. There is reason to believe that harsh policies of encampment displacement will have negative immediate and downstream impacts on this community.

METHODS

Participant observation was conducted weekly or bi-weekly at unhoused encampments in Los Angeles County, USA over the course of two years (2021, 2022). Data were generated through the lens of ontological security theory via in-field jottings and comprehensive field notes. Formal, semi-structured qualitative interviews were conducted with 30 unhoused people who use drugs recruited primarily through peer-referral sampling at these same venues. Data were coded and analyzed thematically using the Template Analysis approach. Field notes were used to triangulate and further contextualize thematic analysis of interview data.

RESULTS

Encampment sweeps impacted nearly all participants and occurred multiple times at every visited field site. They were observed to occur both with and without the presence of police, but always resulted in the loss of the personal property of encampment residents. Sweeps occurred across seasons, hazardous weather, and without offers of alternative shelter. Participants described sweeps as impacting all aspects of their ontological security, including dismantling material and social constancy, disrupting routines of daily life and resource management, increasing feelings of surveillance, and potentially creating negative identity formation.

CONCLUSIONS

In both ethnographic observation and participant interviews, encampment sweeps were noted to be physically, psychologically, and socially destructive. Sweeps left participants feeling anger, loss, and hopelessness while further driving the societal marginalization of unhoused people who use drugs. Sweeps should be discontinued as they harm the capacity of unhoused people to improve their well-being.

Social and structural determinants of injection drug use-associated bacterial and fungal infections: A qualitative systematic review and thematic synthesis

BACKGROUND AND AIMS

Injection drug use-associated bacterial and fungal infections are increasingly common, and social contexts shape individuals' injecting practices and treatment experiences. We sought to synthesize qualitative studies of social-structural factors influencing incidence and treatment of injecting-related infections.

METHODS

We searched PubMed, EMBASE, Scopus, CINAHL and PsycINFO from 1 January 2000 to 18 February 2021. Informed by Rhodes' 'risk environment' framework, we performed thematic synthesis in three stages: (1) line-by-line coding; (2) organizing codes into descriptive themes, reflecting interpretations of study authors; and (3) consolidating descriptive themes into conceptual categories to identify higher-order analytical themes.

RESULTS

We screened 4841 abstracts and included 26 qualitative studies on experiences of injecting-related bacterial and fungal infections. We identified six descriptive themes organized into two analytical themes. The first analytical theme, social production of risk, considered macro-environmental influences. Four descriptive themes highlighted pathways through which this occurs: (1) unregulated drug supply, leading to poor drug quality and solubility; (2) unsafe spaces, influenced by policing practices and insecure housing; (3) health-care policies and practices, leading to negative experiences that discourage access to care; and (4) restrictions on harm reduction programmes, including structural barriers to effective service provision. The second analytical theme, practices of care among people who use drugs, addressed protective strategies that people employ within infection risk environments. Associated descriptive themes were: (5) mutual care, including assisted-injecting and sharing sterile equipment; and (6) self-care, including vein health and self-treatment. Within constraining risk environments, some protective strategies for bacterial infections precipitated other health risks (e.g. HIV transmission).

CONCLUSIONS

Injecting-related bacterial and fungal infections are shaped by modifiable social-structural factors, including poor quality unregulated drugs, criminalization and policing enforcement, insufficient housing, limited harm reduction services and harmful health-care practices. People who inject drugs navigate these barriers while attempting to protect themselves and their community.

"We just don't have the space for it": Geographies of survival and spatial triage in overdose prevention sites

This study explores the role of Overdose Prevention Sites (OPS) within the geographies of survival of vulnerably housed people who use drugs (PWUD) in Vancouver, British Columbia (BC), Canada. In BC, OPS are low-barrier spaces where people may use drugs under monitoring of trained staff. OPS have been established by people who use drugs, activists, and allied organizations as an emergency measure to prevent overdose deaths. However, OPS have other important uses for PWUD who are vulnerably housed and rely on public spaces for survival. Drawing on two years (2018-2020) of ethnographic fieldwork and interviews with fifty-five people who work at and/or use OPS, we explore how OPS operators negotiated multiple and at times competing uses of service space for everyday survival. Data analysis was guided by critical urban theory to explore the place of OPS within PWUD's geographies of survival, with attention to how different uses of space were negotiated within the context of an illicit drug poisoning crisis and urban control practices that displace and exclude unhoused and vulnerably housed PWUD from the city. We find that OPS accommodated other important potential uses of space for unhoused and vulnerably housed PWUD who relied on public space for survival and were routinely displaced by revanchist urban control strategies. Low-barrier approaches and facility enhancements to OPS improved program accessibility and enabled PWUD to use the sites more broadly to meet survival needs including for mutual-aid, sheltering, and income-generation. However, these secondary uses of OPS presented multiple operational challenges as service volumes increased. We observed processes of 'spatial triage' emerge within sites to manage these challenges, which we characterise as a pragmatic set of rules, procedures, and spatial practices that constrained broader uses of OPS within PWUD's geographies of survival. While spatial triage offered a pragmatic way of prioritizing service delivery to address the most acute survival threats of overdose fatality, these practices had unintended and inequitable impacts on service access. Our findings indicate the need for complementary structural changes as part of overdose responses to reduce the need for spatial triage (i.e., safe, affordable housing and drug decriminalisation) and service innovations to mitigate potential harms (e.g., Expanded drop-in and chill spaces, temporary storage spaces for service user).

Community partner perspectives on the implementation of a novel safer supply program in Canada: a qualitative study of the MySafe Project

BACKGROUND

The adulteration of the illicit drug supply with fentanyl and its analogues is driving the ongoing overdose crisis in North America. While various harm reduction interventions address overdose-related risks, there is growing interest in safer supply programs, including the MySafe Project which utilizes a biometric dispensing machine that provides pharmaceutical opioid alternatives to the toxic drug supply. However, the experiences and perspectives of professional community partners on program implementation remain unexplored. This study aims to examine professional community partner perspectives on the feasibility, as well as barriers and facilitators to the implementation of the MySafe program.

METHODS

Semi-structured qualitative interviews were conducted with 17 professional community partners involved in program implementation across four pilot locations in Canada. Thematic analysis of interviews focused on perspectives on safer supply, barriers and facilitators faced during program implementation, and recommendations to inform future scale-up of low-barrier safer supply models across Canada.

RESULTS

Participants identified a variety of barriers, including the dependence on clinician buy-in, coupled with regulatory and logistical constraints. In addition, some participants perceived hydromorphone to be an inadequate substitute to the increasingly toxic street opioid supply. Lastly, technical difficulties were described as barriers to service uptake and delivery. Conversely, having political and community buy-in, availability of wrap-around services, and collaborative communication from the MySafe team served as facilitators to program implementation. Though community partners preferred establishing MySafe machines into existing community organizations, they also discussed benefits of housing-based MySafe programs. The potential role of this program in mid-sized to rural cities was also emphasized.

CONCLUSIONS

To address the overdose crisis, there is an urgent need to implement and evaluate novel solutions that address supply drivers of crisis. Community partner-informed research plays an integral role in ensuring program acceptability and proper implementation. Our findings identify current gaps and facilitators underlying the efficacy of one such model, together with future directions for improvement. Participant recommendations included a diversification of medications offered and types of locations for MySafe programs, a streamlined national approach to prescribing guidelines coupled with more robust training for healthcare professionals, and an emphasis on service delivery within an integrated services model. Our findings underscore a potential gap between the goals of healthcare providers in ensuring comprehensive care and the necessity for low-barrier models such as MySafe that can function both within and outside of integrated service models.

Women who use drugs: engagement in practices of harm reduction care

BACKGROUND

Harm reduction services that employ or are operated by people who use drugs are an effective means of mitigating overdose risks and other drug-related harms. However, stereotypes portraying people who use criminalized drugs as incapable caregivers persist. This is especially true for women who use drugs, and to a greater extent racialized women, who are characterized as having diverged from traditional ideals of womanhood as a result of drug-user stigma and the intersections of gender- and class-based and racist stereotypes. In an effort to identify and understand how women who use drugs practise care through harm reduction, we explored the experiences of women accessing a low-threshold supervised consumption site exclusively for women (transgender and non-binary inclusive) in Vancouver, Canada.

METHODS

Data were drawn from research conducted from May 2017 to June 2018 exploring women's experiences accessing the supervised consumption site during an overdose crisis. Data included forty-five semistructured interviews with women recruited from the site, analysed thematically to explore practices of care through harm reduction.

FINDINGS

Participants reported engaging in both formal and informal care. Acts of care included interventions that both aligned with and deviated from conventional understandings of care practices, including overdose reversal and education, overdose supervision/care, and assisted injection.

CONCLUSION

The boundary between formal and informal harm reduction care is fluid. Women who use drugs engage in harm reduction across these borders with acts of care that align with or fill the gaps in current harm reduction services in order to meet the needs of drug-using communities, challenging negative stereotypes of women who use drugs. However, these caregiving practices can increase risks to care providers' physical, mental, and emotional health and wellness. Increased financial, social, and institutional supports, including safer supply, assisted injection, and community resources, are needed to better support women as they continue to engage in harm reduction care.

Pathways connecting socioeconomic marginalization and overdose: A qualitative narrative synthesis

PURPOSE

This qualitative narrative synthesis sought to identify pathways connecting socioeconomic marginalization (SEM) and overdose for people who use drugs.

METHODS

We included studies with qualitative examination of SEM and fatal and non-fatal overdose published in English between 2000 and 2021. Studies were systematically identified and screened by searching MEDLINE (Ovid), Embase (Ovid), PsycINFO (EBSCOhost), CINAHL (EBSCOhost), Google Scholar, Cochrane Central Registry of Controlled Trials (CENTRAL), and Cochrane Drug and Alcohol Group (CDAG) Specialized Registry, citations, and contacting experts. Risk of bias and quality assessments were performed using the Critical Appraisal Skills Programme checklist and the Confidence in the Evidence from Reviews of Qualitative Research approach. Data were synthesized using a thematic synthesis approach.

RESULTS

The primary search strategy found 5909 articles that met the initial screening criteria. The review and screening process led to a final dataset of 27 qualitative articles. The four key findings of this narrative synthesis revealed aspects of SEM which shaped drug poisoning risk for people who use drugs: (1) resource insufficiency, labor market exclusion and deindustrialization, (2) homelessness and housing, (3) policing, criminalization, and interactions with emergency services, and (4) gendered and racialized dimensions of inequality. Findings led to creating a typology that includes material, behavioral, psychological, social, and environmental pathways that contain multiple mechanisms connecting SEM to overdose. This review revealed reciprocal connections between overdose and SEM via institutional pathways with reinforcing mechanisms, and interrelationships present within and between pathways. Quality assessments indicated moderate confidence in three of four findings (Findings 2,3, and 4 above) and high confidence in one finding (Finding 1).

CONCLUSION

SEM is strongly linked to drug poisoning, and the mechanisms establishing these connections can be classified within four pathways. The interconnectedness of these mechanisms can lead to intensification of overdose risk and reinforcement of SEM itself.

Association between interrupted access to sex work community services during the COVID-19 pandemic and changes in sex workers' occupational conditions: findings from a community-based cohort study in Vancouver, Canada

OBJECTIVES

Globally, criminalisation has shaped sex workers' structural exclusion from occupational protections, and this exclusion has been exacerbated during the COVID-19 pandemic. While community organisations aim to bridge this gap through providing health and safety resources for sex workers, many were forced to scale back services when Canadian provinces declared a state of emergency at the pandemic onset. As little empirical research has examined the impacts of sex work community services interruptions amid COVID-19, our objectives were to (1) examine the correlates of interrupted access to community services and (2) model the independent association between interrupted access to community services and changes in working conditions (ie, self-reported increases in workplace violence or fear of violence), among sex workers during the COVID-19 pandemic.

DESIGN, SETTING AND PARTICIPANTS

As part of an ongoing community-based cohort of sex workers in Vancouver, Canada (An Evaluation of Sex Workers Health Access, 2010-present), 183 participants completed COVID-19 questionnaires between April 2020 and April 2021.

ANALYSIS

Cross-sectional analysis used bivariate and multivariable logistic regression with explanatory and confounder modelling approaches.

RESULTS

18.6% of participants (n=34) reported interrupted access to community services (closure/reduction in drop-in hours, reduced access to spaces offering sex worker supports and/or reduced access/contact with outreach services). In multivariable analysis, sex workers who had difficulty maintaining social supports during COVID-19 (adjusted OR, AOR 2.29, 95% CI 0.95 to 5.56) and who experienced recent non-fatal overdose (AOR 2.71, 95% CI 0.82 to 8.98) faced marginally increased odds of service interruptions. In multivariable confounder analysis, interrupted access to community services during COVID-19 was independently associated with changes in working conditions (ie, self-reported increases in workplace violence or fear of violence; AOR 4.00, 95% CI 1.01 to 15.90).

CONCLUSIONS

Findings highlight concerning implications of community service interruptions for sex workers' labour conditions. Sustainable funding to community organisations is urgently needed to uphold sex workers' occupational safety amid COVID-19 and beyond.

A scoping review of qualitative research on barriers and facilitators to the use of supervised consumption services

A substantial body of evidence demonstrates that supervised consumption services (SCS) mitigate a variety of drug-related harms, including decreasing overdose deaths, infectious disease transmission, and connecting people who use drugs (PWUD) to various health and social services. Research on SCS has predominantly been quantitative, though qualitative research on these services has increased substantially over the last decade. Qualitative methods provide a framework for developing a richer and more nuanced understanding of meanings and contexts associated with drug use, health service implementation, and experience. We present findings from a scoping review of qualitative studies on experiences of PWUD with SCS published between 1997 and 2022. In total, forty-two papers were included in this analysis. Four primary themes emerged from our analysis: 1) Influence of SCS on health and wellbeing among PWUD, 2) the physical environment of SCS can be both a facilitator and barrier to use, 3) social resources can shape and reshape the context within which PWUD benefit from SCS, and 4) various intersecting forces at play both support and harm PWUD in relation to their experiences with SCS. We discuss the primary facilitators and barriers of SCS use and conclude with suggestions to inform future qualitative research, SCS implementation, and PWUD-centered approaches to drug policy.

(Re)situating expertise in community-based overdose response: Insights from an ethnographic study of overdose prevention sites (OPS) in Vancouver, Canada

Overdose Prevention Sites (OPS) are low-barrier services where people may use illicit drugs under the monitoring of staff trained to provide life-saving care in the event of an overdose. In British Columbia (BC), Canada, OPS have been rapidly scaled-up as a community-based response to the overdose crisis and are staffed primarily by community members who are also people who use drugs (PWUD). While it is known that PWUD perform vital roles in OPS and other community-based overdose interventions, the expertise and expert knowledge of PWUD in this work remains under-theorised. This study draws on 20 months of ethnographic fieldwork in Vancouver, BC (July 2018 to March 2020), to explore how OPS responders who are PWUD developed and enacted expertise in overdose response. Ethnographic fieldwork focused on four OPS located in Vancouver's Downtown Eastside (DTES) and Downtown South neighbourhoods. Methods included 100 hours of observation in the sites and surrounding areas, three site-specific focus groups with OPS responders (n=20), and semi-structured interviews with OPS responders (n=14) and service users (n=23). Data was analysed with the aim of characterizing the knowledge underpinning responders' expertise, and the arrangements which allow for the formation and enactment of expertise. We found that OPS responders' expertise was grounded in experiential knowledge acquired through their positionality as PWUD and members of a broader community of activists engaged in mutual aid. Responders became skilled in overdose response through frequent practice and drew on their experiential and embodied knowledge of overdose to provide care that was both technically proficient and responsive to the broader needs of PWUD (e.g. protection from criminalization and stigmatizing treatment). Responders emphasized that the spatial arrangements of OPS supported the development of expertise by facilitating more specialized and comprehensive overdose care. OPS became sites of collective expertise around overdose management as responder teams developed shared understandings of overdose management, including processes for managing uncertainty, delegating team responsibilities, and sharing decision-making. This research re-situates theoretical understandings of expertise in community-based overdose response with implications for overdose prevention interventions. Findings underscore the experiential and embodied expertise of PWUD as community-based responders; the importance of supportive environments and team-based approaches for overdose response; and the benefits of community-driven training that extends beyond technical skills of overdose identification and naloxone administration.

Moving towards a continuum of safer supply options for people who use drugs: A qualitative study exploring national perspectives on safer supply among professional stakeholders in Canada

BACKGROUND

Novel public health interventions are needed to address the toxic drug supply and meet the needs of people who use drugs amidst the overdose crisis. Safer supply - low-barrier distribution of pharmaceutical grade substances - has been implemented in some jurisdictions to provide safer alternatives to the unregulated drug supply, yet no studies to date have explored professional stakeholder perspectives on this approach.

METHODS

We used purposive sampling to recruit professional stakeholders (n = 17) from four locations in British Columbia, Ontario, and Nova Scotia, including program managers, executive directors, political and health authority representatives, and healthcare providers involved in the design, implementation, and/or operation of safer supply programs in their communities. Semi-structured, one-to-one interviews were conducted, and interview data were coded and analyzed using thematic analyses.

RESULTS

Participants defined safer supply as low-barrier access to substances of known quality and quantity, offered on a continuum from prescribed to a legal, regulated supply, and focused on upholding autonomy and liberation of people who use drugs. Stakeholders expressed support for safer supply but explained that current iterations do not meet the needs of all people who use drugs and that implementation is limited by a lack of willing prescribers, stigma towards people who use drugs, and precarity of harm reduction programs to political ideology. Stakeholders expressed strong support for wider-reaching approaches such as decriminalization, legalization, and regulation of substances as a way to fully realize a continuum of safer supply, directly address the overdose crisis and toxic drug supply, and ensure equity of access nationally.

CONCLUSION

The results of this study highlight the need for innovative strategies to address the overdose crisis and that safer supply has the potential to benefit certain people who use drugs. A one-size-fits-all approach is not sufficient and the perspectives of professional stakeholders should be considered alongside those of people who use drugs when designing and implementing future safer supply.

The association of gender with receptive and distributive needle sharing among individuals who inject drugs

Background

Injection drug use and needle sharing remains a public health concern due to the associated risk of HIV, HCV and skin and soft tissue infections. Studies have shown gendered differences in the risk environment of injection drug use, but data are currently limited to smaller urban cohorts.

Methods

To assess the relationship between gender and needle sharing, we analyzed publicly available data from the 2010–2019 National Survey on Drug Use and Health (NSDUH) datasets. Chi-square tests were conducted for descriptive analyses and multivariable logistic regression models were built adjusting for survey year, age, HIV status, and needle source.

Results

Among the entire sample, 19.8% reported receptive needle sharing, 18.8% reported distributive sharing of their last needle, and 37.0% reported reuse of their own needle during last injection. In comparison with men, women had 34% increased odds (OR 1.34, 95% CI 1.11–1.55) of receptive needle sharing and 67% increased odds (OR 1.67, 95% CI 1.41–1.98) of distributive needle sharing. Reuse of one's own needle did not differ by gender.

Conclusions

In this nationally representative sample, we found that women are more likely in comparison with men to share needles both through receptive and distributive means. Expansion of interventions, including syringe service programs, to increase access to sterile injection equipment is of great importance.

Implementation and sustainability of safe consumption sites: a qualitative systematic review and thematic synthesis

BACKGROUND

Safe consumption sites (SCSs) serve diverse populations of people who use drugs (PWUD) and public health objectives. SCS implementation began in the 1980s, and today, there are at least 200 known SCSs operating in over twelve countries. While a growing literature supports their effectiveness as a harm reduction strategy, there is limited information on contextual factors that may support or hinder SCS implementation and sustainability. We aimed to fill this gap in knowledge by reviewing existing qualitative studies on SCSs.

METHODS

We conducted a systematic review and thematic synthesis of qualitative studies. We identified all peer-reviewed, English-language qualitative studies on SCSs containing original data in PubMed, Web of Science, Google Scholar, and Science Direct as of September 23, 2019. Two authors independently screened, abstracted, and coded content relating to SCS implementation and sustainment aligned with the Exploration, Preparation, Implementation, Sustainment (EPIS) implementation science framework.

RESULTS

After removing duplicates, we identified 765 unique records, of which ten qualitative studies met inclusion criteria for our synthesis. Across these ten studies, 236 total interviews were conducted. Overall, studies described how SCSs can (1) keep drug use out of public view while fostering a sense of inclusion for participants, (2) support sustainment by enhancing external communities' acceptability of SCSs, and (3) encourage PWUD utilization. Most studies also described how involving PWUD and peer workers (i.e., those with lived experience) in SCS operation supported implementation and sustainability.

DISCUSSION

Our thematic synthesis of qualitative literature identified engagement of PWUD and additional factors that appear to support SCS planning and operations and are critical to implementation success. However, the existing qualitative literature largely lacked perspectives of SCS staff and other community members who might be able to provide additional insight into factors influencing the implementation and sustainability of this promising public health intervention.

Requiring help injecting among people who inject drugs in Toronto, Canada: Characterising the need to address sociodemographic disparities and substance-use specific patterns

INTRODUCTION

Those requiring help injecting are at an elevated risk of injection-related injury and blood-borne infections and are thus a priority group for harm reduction programs. As supervised consumption services (SCS) are scaled-up across Canada, information on those who require help injecting is necessary to inform equitable service uptake. We characterised the sociodemographic, structural and drug use correlates of needing help injecting among a cohort of people who inject drugs in Toronto, Canada.

METHODS

A cross-sectional baseline survey was administered between November 2018 and March 2020. Unadjusted and multivariable logistic regression models examined associations with requiring help injecting in the past 6 months. A gender-stratified sub-analysis described characteristics of receiving help among those requiring it.

RESULTS

Of 701 participants (31.0% cisgender women), 294 (41.9%) needed recent help injecting. In unadjusted analyses, being a racialised, non-Indigenous person (odds ratio [OR] 1.79, 95% confidence interval [CI] 1.13-2.86) or a cisgender woman (OR 1.72, 95% CI 1.24-2.39) were associated with needing help. In multivariable analyses, requiring assistance was associated with needing frequent help preparing drugs (adjusted OR [AOR] 9.52, 95% CI 4.78-21.28), fewer years since first injection (AOR for 1 year increase: 0.97, 95% CI 0.95-0.99) and injecting stimulants. Among those who required help, cisgender women reported needing assistance more often than cisgender men (P = 0.009).

DISCUSSION AND CONCLUSIONS

Over two-fifths of the sample required help injecting; requiring assistance was associated with sociodemographic indicators and substance use-specific patterns. Findings highlight the need to scale-up educational resources for those who receive or provide help injecting, as well as SCS that accommodate onsite injection assistance.

Establishment and Enforcement of Operational Rules at an Unsanctioned Safe Drug Consumption Site in the United States, 2014-2020

Objectives. To examine how operational rules are established and enforced at an unsanctioned safe consumption site (SCS) operating in the United States. Methods. We conducted 44 qualitative interviews with people who use drugs, staff members, and volunteers at an unsanctioned SCS and analyzed them using an inductive thematic approach. Results. Rule-making processes were largely driven by concerns raised by service users rather than driven by external pressures, and iterated rapidly in response to changing needs. The unsanctioned nature of the site produced an environment where bottom-up rule-making was critical to generating a shared sense of ownership of the site and where enforcement was necessarily fluid. Conclusions. Removing external restrictions on operational rules for SCSs results in a flexible set of rules that are highly responsive to the social and public health needs of people who use drugs. Legislation and regulations of SCSs should aim to place as few hard limits on operating conditions as possible to maximize involvement of and responsiveness to people who use drugs.

Health impacts of a scale-up of supervised injection services in a Canadian setting: an interrupted time series analysis

BACKGROUND AND AIMS

In response to a dramatic rise in overdose deaths due to injection drug use, there was a rapid scale-up of low-threshold supervised injection services (SIS), termed 'overdose prevention sites' (OPS), in Vancouver, Canada in December 2016. We measured the potential impact of this intervention on SIS use and related health outcomes among people who inject drugs (PWID).

DESIGN

Segmented regression analyses of interrupted time series data from two community-recruited prospective cohorts of PWID from January 2015 to November 2018 were used to measure the impact of the OPS scale-up on changes in SIS use, public injection, syringe sharing and addiction treatment participation, controlling for pre-existing secular trends.

SETTING

Vancouver, Canada.

PARTICIPANTS

Of 745 PWID, 292 (39.7%) were women, 441 (59.6%) self-reported white ancestry and the median age was 47 years (interquartile range = 38, 53) at baseline.

MEASUREMENTS

Immediate (i.e. step level) and gradual (i.e. slope) changes in the monthly proportion of participants who self-reported past 6-month SIS use, public injection, syringe sharing and participation in any form of addiction treatment.

FINDINGS

Post OPS expansion, the monthly prevalence of SIS use immediately increased by an estimated 6.4% [95% confidence interval (CI) = 1.7, 11.2] and subsequently further increased by an estimated 0.7% (95% CI = 0.3, 1.1) per month. The monthly prevalence of addiction treatment participation immediately increased by an estimated 4.5% (95% CI = 0.5, 8.5) following the OPS expansion, while public injection and syringe sharing were estimated to immediately decrease by 5.5% (95% CI = 0.9, 10.0) and 2.5% (95% CI = 0.5, 4.6), respectively. Findings were inconclusive as to whether or not an association was present between the intervention and subsequent gradual changes in public injection, syringe sharing and addiction treatment participation.

CONCLUSIONS

Scaling-up overdose prevention sites in Vancouver, Canada in December 2016 was associated with immediate and continued gradual increases in supervised injection service engagement and immediate increases in related health benefits.

A Systematic Review of Gender-Based Violence Prevention and Response Interventions for HIV Key Populations: Female Sex Workers, Men Who Have Sex With Men, and People Who Inject Drugs

Gender-based violence (GBV) is that perpetrated based on sex, gender identity, or perceived adherence to socially defined gender norms. This human rights violation is disproportionately experienced by HIV key populations including female sex workers (FSW), people who inject drugs (PWID), and men who have sex with men (MSM). Consequently, addressing GBV is a global priority in HIV response. There is limited consensus about optimal interventions and little known about effectiveness. Our systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was registered in International Prospective Register of Systematic Reviews. Peer-reviewed and non-peer-reviewed literature were searched for articles that described a GBV prevention or response intervention specifically for key populations including FSW, PWID, and MSM. Results were organized by level(s) of implementation and pillars of a comprehensive GBV response: prevention, survivor support, and accountability/justice. Of 4,287 articles following removal of duplicates, 32 unique interventions (21 FSW, seven PWID, and nine MSM, not mutually exclusive) met inclusion criteria, representing 13 countries. Multisectoral interventions blended empowerment, advocacy, and crisis response with reductions in violence. Individual-level interventions included violence screening and response services. Violence-related safety promotion and risk reduction counseling within HIV risk reduction programming reduced violence. Quantitative evaluations were limited. Violence prevention and response interventions for FSW, PWID, and MSM span individual, community, and multisectoral levels with evidence of promising practices at each level. The strongest evidence supported addressing violence in the context of sexually transmitted infection/HIV risk reduction. As interventions continue to emerge, the rigor of accompanying evaluations must simultaneously advance to enable clarity on the health and safety impact of GBV prevention and response programming.

Assessing the feasibility, acceptability and accessibility of a peer-delivered intervention to reduce harm and improve the well-being of people who experience homelessness with problem substance use: the SHARPS study

BACKGROUND

For people experiencing homelessness and problem substance use, access to appropriate services can be challenging. There is evidence that the development of trusting relationships with non-judgemental staff can facilitate service engagement. Peer-delivered approaches show particular promise, but the evidence base is still developing.

METHODS

The study used mixed methods to assess the feasibility, acceptability and accessibility of a peer-delivered, relational intervention to reduce harms and improve health/well-being, quality of life and social functioning, for people experiencing homelessness and problem substance use. Four Peer Navigators were employed to support individuals (n = 68 total, intervention participants). They were based in outreach services and hostels in Scotland and England. Qualitative interviews were conducted with intervention participants, Peer Navigators and staff in services, and observations were conducted in all settings. Quantitative outcomes relating to participants' substance use, physical and mental health, and quality of the Peer Navigator relationship, were measured via a 'holistic health check' with six questionnaires completed at two time-points.

RESULTS

The intervention was found to be acceptable to, and feasible and accessible for, participants, Peer Navigators, and service staff. Participants reported improvements to service engagement, and feeling more equipped to access services independently. The lived experience of the Peer Navigators was highlighted as particularly helpful, enabling trusting, authentic, and meaningful relationships to be developed. Some challenges were experienced in relation to the 'fit' of the intervention within some settings. Among participants there were reductions in drug use and risky injecting practices. There were increases in the number of participants receiving opioid substitution therapy. Overall, the intervention was positively received, with collective recognition that the intervention was unique and highly valuable. While most of the measures chosen for the holistic health check were found to be suitable for this population, they should be streamlined to avoid duplication and participant burden.

CONCLUSIONS

The study established that a peer-delivered, relational harm reduction intervention is acceptable to, and feasible and accessible for, people experiencing homelessness and problem substance use. While the study was not outcomes-focused, participants did experience a range of positive outcomes. A full randomised controlled trial is now required to assess intervention effectiveness.

A peer-delivered intervention to reduce harm and improve the well-being of homeless people with problem substance use: the SHARPS feasibility mixed-methods study

BACKGROUND

For people experiencing homelessness and problem substance use, access to appropriate services can be challenging. There is evidence that development of trusting relationships with non-judgemental staff can facilitate service engagement. Peer-delivered approaches show particular promise, but the evidence base is still developing. This study tested the feasibility and acceptability of a peer-delivered intervention, through 'Peer Navigators', to support people who are homeless with problem substance use to address a range of health and social issues.

OBJECTIVES

The study objectives were to design and implement a peer-delivered, relational intervention to reduce harms and improve health/well-being, quality of life and social functioning for people experiencing homelessness and problem substance use, and to conduct a concurrent process evaluation to inform a future randomised controlled trial.

DESIGN

A mixed-methods feasibility study with concurrent process evaluation was conducted, involving qualitative interviews [staff interviews (one time point), n = 12; Peer Navigator interviews (three or four time points), n = 15; intervention participant interviews: first time point, n = 24, and second time point, n = 10], observations and quantitative outcome measures.

SETTING

The intervention was delivered in three outreach services for people who are homeless in Scotland, and three Salvation Army hostels in England; there were two standard care settings: an outreach service in Scotland and a hostel in England.

PARTICIPANTS

Participants were people experiencing homelessness and problem substance use (n = 68) (intervention).

INTERVENTION

This was a peer-delivered, relational intervention drawing on principles of psychologically informed environments, with Peer Navigators providing practical and emotional support.

MAIN OUTCOME MEASURES

Outcomes relating to participants' substance use, participants' physical and mental health needs, and the quality of Peer Navigator relationships were measured via a 'holistic health check', with six questionnaires completed at two time points: a specially created sociodemographic, health and housing status questionnaire; the Patient Health Questionnaire-9 items plus the Generalised Anxiety Disorder-7; the Maudsley Addiction Profile; the Substance Use Recovery Evaluator; the RAND Corporation Short Form survey-36 items; and the Consultation and Relational Empathy Measure.

RESULTS

The Supporting Harm Reduction through Peer Support (SHARPS) study was found to be acceptable to, and feasible for, intervention participants, staff and Peer Navigators. Among participants, there was reduced drug use and an increase in the number of prescriptions for opioid substitution therapy. There were reductions in risky injecting practice and risky sexual behaviour. Participants reported improvements to service engagement and felt more equipped to access services on their own. The lived experience of the Peer Navigators was highlighted as particularly helpful, enabling the development of trusting, authentic and meaningful relationships. The relationship with the Peer Navigator was measured as excellent at baseline and follow-up. Some challenges were experienced in relation to the 'fit' of the intervention within some settings and will inform future studies.

LIMITATIONS

Some participants did not complete the outcome measures, or did not complete both sets, meaning that we do not have baseline and/or follow-up data for all. The standard care data sample sizes make comparison between settings limited.

CONCLUSIONS

A randomised controlled trial is recommended to assess the effectiveness of the Peer Navigator intervention.

FUTURE WORK

A definitive cluster randomised controlled trial should particularly consider setting selection, outcomes and quantitative data collection instruments.

TRIAL REGISTRATION

This trial is registered as ISRCTN15900054.

A Thematic Synthesis of the Roles of Nurses at Safer Consumption Sites

ABSTRACT

Opioid use, particularly via injection, is associated with an increased risk of infection, injury, and death. Safer consumption sites (SCSs), where people may consume previously obtained drugs under observation, have been shown to reduce these risks among people who use drugs. Most SCSs employ nurses, but there is limited research into their roles. The objective of this article is to describe and synthesize the roles of nurses at SCSs to better understand their importance in a rapidly proliferating public health intervention. We extracted data from 48 qualitative, quantitative, peer-reviewed, and gray literature, as well as primary source narrative articles on SCSs, whether they were explicitly about nursing or not. We coded each mention of nurses or nursing in each article and identified 11 descriptive themes or roles that SCS nurses carry out. From these, we identified the following three analytical themes or hypotheses about the character of these roles: (a) The primary aim of SCS nursing care is to reduce morbidity and mortality; (b) SCS nurses create a therapeutic community; and (c) SCS nurses engage in research, professional activities, and activism to better understand and promote SCSs. More research into the roles of SCS nurses is needed to better serve a vulnerable population.

Peer Support and Overdose Prevention Responses: A Systematic 'State-of-the-Art' Review

Overdose prevention for people who use illicit drugs is essential during the current overdose crisis. Peer support is a process whereby individuals with lived or living experience of a particular phenomenon provide support to others by explicitly drawing on these experiences. This review provides a systematic search and evidence synthesis of peer support within overdose prevention interventions for people who use illicit drugs. A systematic search of six databases (CINAHL, SocINDEX, PsycINFO, MEDLINE, Scopus, and Web of Knowledge) was conducted in November 2020 for papers published in English between 2000 and 2020. Following screening and full-text review, 46 papers met criteria and were included in this review. A thematic analysis approach was used to synthesize themes. Important findings include: the value of peers in creating trusted services; the diversity of peers' roles; the implications of barriers on peer-involved overdose prevention interventions; and the stress and trauma experienced by peers. Peers play a pivotal role in overdose prevention interventions for people who use illicit drugs and are essential to the acceptability and feasibility of such services. However, peers face considerable challenges within their roles, including trauma and burnout. Future interventions must consider how to support and strengthen peer roles in overdose settings.

Negotiating sex work and client interactions in the context of a fentanyl-related overdose epidemic

Despite awareness of the role of drug use in shaping sex worker/client interactions, these dynamics remain poorly understood in the context of illicit fentanyl-driven overdose epidemics. This study examined sex workers' experiences negotiating client interactions amidst a toxic drug supply in Vancouver, Canada. Findings draw from two ethnographic studies. The first, conducted between December 2016 and May 2017, examined the rapid implementation of several low-threshold supervised consumption sites. The second investigated experiences of women accessing a women-only site from May 2017 to June 2018. Data included 200 hours of fieldwork and in-depth semi-structured interviews with 34 street-based sex workers who use illicit drugs. Data were analysed thematically with attention to the risk environment. Participants described providing harm reduction services to clients as a means to reduce overdose-related risks, thus increasing sex workers' hidden labour. Participants, comments regarding criminalisation and stigma surrounding drug use and sex work indicated a reticence to report overdoses, thereby potentially increasing the risks of overdose-related harms, including death. There is an urgent need for sex worker-led overdose prevention strategies that prioritise health and safety of sex workers and their clients with specific attention to how the criminalisation of particular drugs, practices and people contributes to overdose-related risks.

Health programmes and services addressing the prevention and management of infectious diseases in people who inject drugs in Canada: a systematic integrative review

OBJECTIVES

People who inject drugs (PWID) experience a high burden of injection drug use-related infectious disease and challenges in accessing adequate care. This study sought to identify programmes and services in Canada addressing the prevention and management of infectious disease in PWID.

DESIGN

This study employed a systematic integrative review methodology. Electronic databases (PubMed, CINAHL and Web of Science Core Collection) and relevant websites were searched for literature published between 2008 and 2019 (last search date was 6 June 2019). Eligible articles and documents were required to address injection or intravenous drug use and health programmes or services relating to the prevention or management of infectious diseases in Canada.

RESULTS

This study identified 1607 unique articles and 97 were included in this study. The health programmes and services identified included testing and management of HIV and hepatitis C virus (n=27), supervised injection facilities (n=19), medication treatment for opioid use disorder (n=12), integrated infectious disease and addiction programmes (n=10), needle exchange programmes (n=9), harm reduction strategies broadly (n=6), mobile care initiatives (n=5), peer-delivered services (n=3), management of IDU-related bacterial infections (n=2) and others (n=4). Key implications for policy, practice and future research were identified based on the results of the included studies, which include addressing individual and systemic factors that impede care, furthering evaluation of programmes and the need to provide comprehensive care to PWID, involving medical care, social support and harm reduction.

CONCLUSIONS

These results demonstrate the need for expanded services across a variety of settings and populations. Our study emphasises the importance of addressing social and structural factors that impede infectious disease care for PWID. Further research is needed to improve evaluation of health programmes and services and contextual factors surrounding accessing services or returning to care.

Harm Reduction Services in Ottawa: The Culture of Drug Use

Between January 2016 and June 2019, there were over 13,900 apparent opioid-related deaths in Canada, solidifying the need for appropriate and effective services for people who use drugs (PWUD). Within government initiatives and policies, PWUD are often inappropriately considered a homogeneous group of individuals, with implementation of services nationally often being guided by these governmental bodies without meaningful consultation and collaboration with PWUD. However, recent harm reduction research and best practice guidelines have emphasized the importance of tailoring services to local drug scenes. Despite this, very little research on the cultural norms of PWUD exists in the literature. In an attempt to explore the local culture of drug use in Ottawa, a literature review ultimately uncovered very few articles on this topic. However, by expanding the search beyond Ottawa and using a social determinants of health framework, the factors of culture, income and social status, physical environment, and access to services were revealed as unique experiences for PWUD. Further, through four in-depth interviews with current harm reduction providers in Ottawa, the themes of (1) uncertainty and concerns surrounding the overdose crisis; (2) lack of flexibility in resources and access issues; and (3) diversity in the culture of drug use in Ottawa were explored. Recommendations surrounding partnering with PWUD, policy changes, and a safer supply were subsequently discussed. These findings helped to validate the reality of the unique drug-use culture in Ottawa, and the requirement for harm reduction services to be adapted to the local needs of PWUD.

A qualitative study on overdose response in the era of COVID-19 and beyond: how to spot someone so they never have to use alone

BACKGROUND

Spotting is an informal practice among people who use drugs (PWUD) where they witness other people using drugs and respond if an overdose occurs. During COVID-19 restrictions, remote spotting (e.g., using a telephone, video call, and/or a social media app) emerged to address physical distancing requirements and reduced access to harm reduction and/or sexually transmitted blood borne infection (STBBI's) prevention services. We explored spotting implementation issues from the perspectives of spotters and spottees.

METHODS

Research assistants with lived/living expertise of drug use used personal networks and word of mouth to recruit PWUD from Ontario and Nova Scotia who provided or used informal spotting. All participants completed a semi-structured, audio-recorded telephone interview about spotting service design, benefits, challenges, and recommendations. Recordings were transcribed and thematic analysis was used.

RESULTS

We interviewed 20 individuals between 08/2020-11/2020 who were involved in informal spotting. Spotting was provided on various platforms (e.g., telephone, video calls, and through texts) and locations (e.g. home, car), offered connection and community support, and addressed barriers to the use of supervised consumption sites (e.g., location, stigma, confidentiality, safety, availability, COVID-19 related closures). Spotting calls often began with setting an overdose response plan (i.e., when and who to call). Many participants noted that, due to the criminalization of drug use and fear of arrest, they preferred that roommates/friends/family members be called instead of emergency services in case of an overdose. Both spotters and spottees raised concerns about the timeliness of overdose response, particularly in remote and rural settings.

CONCLUSION

Spotting is a novel addition to, but not replacement for, existing harm reduction services. To optimize overdose/COVID-19/STBBI's prevention services, additional supports (e.g., changes to Good Samaritan Laws) are needed. The criminalization of drug use may limit uptake of formal spotting services.

Drug places and spaces of problematisation: the melancholy case of a Hungarian needle exchange programme

Purpose

This paper aims to explore multiple problematisation processes through a former needle exchange programme run by Kék Pont (a non-governmental organisation) in the 8th district of Budapest. By presenting a collage of ethnographic stories, this paper attempts to preserve tacit knowledge associated with the programme and thereby keep its office alive as a “drug place”, the operation of which was made impossible in 2014.

Design/methodology/approach

Drawing on the insights of Foucauldian governmentality studies and actor-network theory, this paper focusses on drug use as a problem in its spatial-material settings. Based on ethnographic fieldwork, the contribution traces multiple problematisation processes and related infrastructures.

Findings

From the needle exchange programme’s perspective, drug use is not a singular problem but the effect of multiple problematisation processes. Although those processes are often in conflict with each other, the question is not which one is right, but how social workers manage to hold them together. It is a fragile achievement that requires years of training and ongoing negotiation with local actors. By eliminating Kék Pont’s 8th district office, the Hungarian Government did not only hinder harm reduction in the area but it had also rendered tacit knowledge associated with the needle exchange programme as a “drug place” inaccessible.

Originality/value

The paper is a melancholy intervention – an attempt to preserve tacit knowledge that had accumulated at the needle exchange programme. The retelling of ethnographic stories about this “drug place” is one way of ensuring that other drug policies remain imaginable.

Assisted injection provider practices and motivations in Los Angeles and San Francisco California 2016-18

BACKGROUND

Assisted injection is a high-risk and common practice among people who inject drugs (PWID) and occurs for diverse reasons according to qualitative research. To develop interventions for reducing assisted injection risks, it is important to understand the practices of PWID who provide injection assistance, including their motivations for providing assistance.

METHODS

Using follow-up data from an efficacy trial among PWID recruited in Los Angeles and San Francisco, CA (n=601), we present descriptive statistics on motivations for providing injection assistance and use multivariable logistic regression modelling to examine factors associated with these motivations.

RESULTS

PWID provided injection assistance most commonly to friends and acquaintances. A quarter provided assistance on a daily basis. The most common motivations for providing assistance were skill and injury prevention. PWID also provided assistance to stop pestering and for compensation in money or drugs. In separate models examining factors associated with the five main motivations, we found injury prevention to be associated with skill injecting others, neck injection, methamphetamine use, and recycling income. Pestering was associated with injury prevention, neck and hand injection, speedball use, and syringe selling. Skill was associated with injury prevention, neck and hand injection, being physically assaulted, and age. Providing assistance for money was associated with providing assistance for food or drugs, armpit injections, being female, and providing assistance more frequently. Providing assistance for drugs was associated with compensation in food or money, goofball injection, selling drugs, and panhandling.

CONCLUSION

Providing injection assistance is associated with injection needs of recipients and drug scene participation. We urgently need new interventions for reducing assisted injection risks. Since injection providers report being motivated by skill and to prevent injury, interventions such as training in safer injection techniques are likely to be met with enthusiasm.

Navigating post-eviction drug use amidst a changing drug supply: A spatially-oriented qualitative study of overlapping housing and overdose crises in Vancouver, Canada

BACKGROUND

North American cities are experiencing intersecting housing and overdose crises as illicit drug markets become marked by the proliferation of fentanyl and methamphetamine. Despite recent research documenting associations between evictions and drug-related risks and harms, including overdose, the mechanisms through which these occur remain poorly understood. This study to examines how evictions shape the drug use practices of people who use drugs in Vancouver's Downtown Eastside - a neighbourhood with an established drug scene - as the illicit drug supply changed.

METHODS

Qualitative interviews and geo-spatial data collection were conducted with 56 recently evicted PWUD. Data were analyzed by interfacing qualitative and geo-spatial data, and interpreted focusing on how structural vulnerability shaped spatial practices and drug-related risks post-eviction.

RESULTS

Findings demonstrate how post-eviction spatial practices and routines produced risk and harm as participants navigated the uncertainties of housing vulnerability and drug supply changes. Post-eviction disruptions complicated participants' ability to engage with trusted drug sellers. Changes to spatial patterns and access to private spaces rendered public drug use inevitable, though this was mitigated to some degree by harm reduction supports. Abrupt changes to drug use patterns occurred due to post-eviction disruptions and included instrumental uses of methamphetamine to increase alertness and navigate survival amidst severe hardship.

CONCLUSIONS

Findings demonstrate how post-eviction changes to routines and spatial patterns are framed by structural vulnerability and can exacerbate drug-related harms, particularly in the context of a changing drug supply. There is an urgent need for structural interventions and harm reduction responses to mitigate harms associated with evictions.

[Public policies for people who use drugs: Strategies for the elimination of stigma and the promotion of human rights]

This paper aims to provide theoretically informed practical proposals for the improvement of current drug policies, which are based on a biological model of disease and the criminalization of people who use drugs. First, we present alternatives to a biologically-oriented scientific conception centered around neuroscientific postulates, which support the idea that the etiology of addiction materializes in the brain, in favor of models based on the social sciences where context plays a relevant role in the description and management approaches regarding different uses of psychoactive substances. Second, epistemological models and proposals are offered from a practical perspective to sustain or implement policies and programs in accordance with a more sustainable approach based on the elimination of stigma and the promotion of political participation of people who use drugs. In short, drug policies based on human rights.

Peer-assisted injection as a harm reduction measure in a supervised consumption service: a qualitative study of client experiences

Background

Peer assistance is an emerging area of study in injection drug use. When Canada’s first supervised consumption site (SCS) opened in 2003 in Vancouver, Canada, clients were prohibited from injecting their peers; only recently has this practise been introduced as a harm reduction measure at these sites. In 2018, Health Canada granted federal exemption to allow peer-assisted injection at certain SCS sites, under the Controlled Drugs and Substances Act. Literature pertaining to peer-assisted injection addresses several topics: interpersonal relationships between the injection provider and recipient; the role of pragmatism; trust and expertise; and gender relations.

Methods

In this qualitative study, participants (n = 16) were recruited to be interviewed about their experiences in a peer-assisted injection program (PAIP) at one SCS regulated by Health Canada. Interview data were transcribed and thematically analyzed. Quantitative administrative data were used to provide context and to describe the study population, comprised of people in the PAIP (n = 248).

Results

PAIP clients made up 17.4% of all SCS clients. PAIP clients were more likely to be female and Indigenous. Injection providers expressed being moved by compassion to help others inject. While their desire to assist was pragmatic, they felt a significant burden of responsibility for the outcomes. Other prominent factors related to the injection provider-recipient relationship were social connection, trust, safety, social capital, and reciprocity. Participants also made suggestions for improving the PAIP which included adding more inhalation rooms so that if someone was unable to inject they could smoke in a safe place instead. Additionally, being required by law to divide drugs outside of the SCS, prior to preparing and using in the site, created unsafe conditions for clients.

Conclusions

Regular use of the SCS, and access to its resources, enabled participants to lower their risk through smoking and to practice lower-risk injections. At the federal level, there is considerable room to advocate for allowing clients to divide drugs safely within the SCS, and to increase capacity for safer alternatives such as inhalation.

"And we just have to keep going": Task shifting and the production of burnout among overdose response workers with lived experience

Overdose response programs in North America increasingly employ task shifting-shifting overdose response tasks to less specialized workers-to increase effectiveness and promote involvement of people with lived/living experience of drug use (PWLE). In Canada, task shifting has occurred through community-driven implementation of overdose response programs staffed primarily by PWLE. The implications of this task shifting on workers' well-being and service delivery has received little scholarly consideration, despite reports of widespread burnout among frontline responders. This study examines experiences and drivers of burnout among PWLE working at low-barrier supervised consumption sites ("Overdose Prevention Sites" or OPSs) in Vancouver, Canada. Between December 2016 and March 2020, we conducted ethnographic fieldwork at four OPSs, including in-depth interviews with 23 overdose response workers, three site-based focus groups with 20 additional workers, and 150 h of naturalistic observation. Data were analyzed to explore how working conditions, labour arrangements, economic insecurity and social disadvantage shaped burnout. We found that overdose response workers commonly reported burnout, which they attributed to the precarious and demanding nature of their work. While casual positions offered low-barrier employment, PWLE often lacked the wages and benefits enjoyed by other frontline workers, with limited supports and opportunities for advancement. Due to their social position within drug-using networks, PWLE's work encompassed hidden care work that participants felt was constant and undervalued. The scarcity of permanent full-time positions, alongside barriers to transitioning into formal employment, prevented many PWLE from earning livable wages or taking time off to 'recharge.' This study highlights how the devaluing and casualization of overdose response labour, compounded by other dimensions of structural vulnerability, are central to burnout among overdose response workers with lived experience. Interventions to address burnout within this setting must extend beyond individual-level interventions (e.g. counselling, self-care) to also strengthen working conditions and economic security of PWLE.

Rules and Eligibility Criteria for Supervised Consumption Services Feasibility Studies - A Scoping Review

INTRODUCTION

Supervised consumption services (SCS) reduce HIV risks and overdose for people who use drugs (PWUD) and are known to have wide-ranging public health benefits. Feasibility studies are often conducted as part of program/implementation development. We conducted a scoping review of SCS feasibility/pre-implementation studies to answer: what is known about stakeholders' opinions of SCS rules and eligibility criteria?

METHODS

Using the PRISMA-ScR guidelines, we searched Medline, PsychINFO, Embase, CINAHL, and SCOPUS databases for: (a) empirical research, (b) reported in English, (c) focused on SCS, (d) pre-implementation feasibility studies (research conducted prior to implementation of SCS in a given context), (e) examining SCS operational rules and eligibility criteria. Abstracts were reviewed to verify appropriateness; full articles/reports were retrieved; data were extracted and charted.

RESULTS

Of the 1,268 data sources identified/reviewed, 19 sources, were included. Manuscripts showed the following criteria that might be considered when determining who can and cannot use SCS: age, pregnancy status, and opioid substitution treatment status. To govern behaviours at SCS, manuscripts focused on: acceptable modes of drug consumption, assisted injections, sharing drugs on-site, pill injecting, and mandatory hand washing, etc. Stakeholders generally agreed that; eligibility restrictions and site rules should be minimal to establish low-barrier services. SCS are often forced to contend with the tension between adhering to a medical or public health model and creating low-barrier services. SCS rules are at the center of this intersection because rules and eligibility criteria implemented to mirror other health services may not align with the needs of PWUD.

CONCLUSION

Given the public health significance of SCS, establishing best practices for service delivery is critical for increasing access and addressing implementation issues. Future research should examine other operational elements of SCS, such as design elements, staffing models, and ancillary services. Additional research should also focus on supervised smoking services.

Operational and contextual barriers to accessing supervised consumption services in two Canadian cities

BACKGROUND AND AIMS

While previous scholarship has documented barriers to Supervised Consumption Services (SCS) access, little is known about how Non-SCS-users perceive available, sanctioned SCS, and how such perceptions may hinder their SCS use. The objectives of this study were to examine: 1) barriers to accessing SCS for SCS-users and Non-SCS-users; and 2) the extent to which these barriers are consistent between groups.

METHODS

We conducted semi-structured interviews with 75 PWUD in two cities in Western Canada, Edmonton and Calgary, who may or may not have accessed available SCS. Participants were recruited on the streets near SCS via traditional fieldwork and snowball sampling. We employed a generalized prompt guide and asked a range of questions about how PWUD perceived and/or experienced SCS in the area. All interviews were digitally recorded, transcribed, thematically coded, and analysed.

RESULTS

Despite PWUD's generally positive perceptions of SCS, we identified several operational barriers to SCS access, including wait times and time limits, restrictions on injection assistance, and client bans from clinics. We also identified contextual barriers, including perceptions of the 'unnecessary' use of naloxone and police surveillance. Importantly, these barriers were consistent between SCS-users and Non-SCS-users, though some SCS-users actively worked to counter contextual barriers among peers.

CONCLUSION

Operational and contextual barriers to SCS use contribute to intermittent access for existing clients and preclude SCS access for others. Addressing such barriers may increase SCS uptake, thereby further extending the well-documented and critical reach of these harm reduction initiatives.

Buprenorphine dispensing in an epicenter of the U.S. opioid epidemic: A case study of the rural risk environment in Appalachian Kentucky

BACKGROUND

Buprenorphine is a cornerstone to curbing opioid epidemics, but emerging data suggest that rural pharmacists in the US sometimes refuse to dispense this medication. We conducted a case study to explore buprenorphine dispensing practices in 12 rural Appalachian Kentucky counties, and analyze whether and how they were shaped by features of the rural risk environment.

METHODS

In this case study, we conducted one-on-one semi-structured interviews with 14 pharmacists operating 15 pharmacies in these counties to explore buprenorphine dispensing practices and perceived influences on these practices. Thematic analyses of the resulting transcripts revealed three features of the rural risk environment that shaped dispensing. To explore these three risk environment features, we analyzed policy documents (e.g., Attorney General lawsuits) and administrative databases (e.g., incarceration data). Textual documents were analyzed using thematic analyses and administrative data were analyzed using descriptive statistics; memoes explored relationships among risk environment features and dispensing practices.

RESULTS

Twelve of the 15 pharmacies limited dispensing, by refusing to serve new patients; limiting dispensing to known patients or prescribers; or refusing to dispense buprenorphine altogether. Concerns about exceeding a "Drug Enforcement Administration (DEA) cap" on opioid dispensing stifled dispensing. A legacy of aggressive and fraudulent marketing of opioid analgesics (OAs) by pharmaceutical companies and physician OA overprescribing undermined pharmacist trust in buprenorphine and in its prescribers. The escalating local war on drugs may have undermined dispensing by reinforcing stigma against people who use drugs.

CONCLUSIONS

Initiatives to increase buprenorphine prescribing must be accompanied by policy changes to increase dispensing. Specifically, buprenorphine should be removed from opioid monitoring systems; efforts to de-escalate the war on drugs should be extended to encompass rural areas; initiatives to dismantle aggressive OA marketing should be strengthened; and efforts to re-build pharmacist trust in physicians are needed.

Assisted injection within supervised injection services: Uptake and client characteristics among people who require help injecting in a Canadian setting

BACKGROUND

People who require help injecting illicit drugs experience elevated rates of a range of health-related harms, including overdose and acquisition of blood-borne pathogens. In response, some supervised injection services (SIS) in Canada have begun to permit clients to be physically injected by fellow clients or staff members. However, little is known about uptake and characteristics of clients who engage in this practice. We therefore sought to examine factors associated with receiving injection assistance at SIS among people who require help injecting drugs in Vancouver, Canada.

METHODS

Data were drawn from two community-recruited prospective cohort studies of people who inject drugs (PWID). We used multivariable generalized estimating equation (GEE) analyses with time-updated covariates to identify factors associated with self-reported receipt of injection assistance at SIS.

RESULTS

Between June 2017 and December 2018, 319 individuals who reported having recently required help injecting were included in the study. Of these, 160 (51.0%) were women and the median age was 42 years at baseline. In total, 54 (16.9%) participants reported receiving injection assistance at a SIS at least once over an average of 3.3 months of follow-up. In multivariable GEE analyses, recent homelessness (Adjusted Odds Ratio [AOR] = 2.04; 95% confidence interval [CI]: 1.13 - 3.66), fentanyl injection (AOR = 3.45; 95% CI: 1.42 - 8.41), non-fatal overdose (AOR = 1.86; 95% CI: 1.02 - 3.38) and enrolment in methadone maintenance therapy (AOR = 1.89; 95% CI: 1.03 - 3.47) were associated with increased odds of receiving injection assistance at SIS.

CONCLUSION

Although uptake of assisted injection at SIS was relatively low among this sample of people who require help injecting, this practice was associated with several indicators of structural vulnerability and drug-related risk. These findings suggest that accommodating assisted injection within SIS may be providing opportunities to engage and reduce harms among higher-risk subpopulations of PWID in this setting.

Elevated prevalence of self-reported unintentional exposure to fentanyl among women who use drugs in a Canadian setting: A cross-sectional analysis

BACKGROUND

The United States and Canada are in the midst of an overdose epidemic, fueled by illicitly manufactured fentanyl. While marked differences in vulnerability to drug-related harm between men and women who use drugs is well characterized, the extent to which gender differences manifest in the present overdose crisis remains understudied. We examined differences in self-reported unintentional exposure to fentanyl between men and women who use drugs.

METHODOLOGY

Data were derived from three prospective cohorts of people who use drugs in Vancouver, Canada. Survey data were extracted on individuals who self-reported having used drugs known or believed to contain fentanyl in the past 30 days between December 2016 and November 2017. We used multivariable logistic regression (MLR) to examine the relationship between self-identified gender (woman vs. man) and self-reported unintentional exposure to fentanyl. As a sub-analysis, correlates of self-reported unintentional exposure to fentanyl were identified using MLR, stratified by gender.

RESULTS

Of 578 eligible participants, including 219 (37.9%) women, 200 (33.2%) perceived their exposure to fentanyl as unintentional (40.2% among women and 29.0% among men). In the MLR, being a woman was positively associated with self-reported unintentional fentanyl exposure (adjusted odds ratio = 2.11; 95% confidence interval: 1.45-3.09). Among women at least daily heroin use was negatively associated with self-reported unintentional fentanyl exposure, while perceiving a high or moderate risk of overdosing on fentanyl was positively associated with outcome. Among men older age was positively associated with self-reported unintentional fentanyl exposure, while injection drug use and at least daily heroin use was negatively associated with the outcome (all p<0.05).

CONCLUSIONS

Women were more than two times as likely to self-report they were unintentionally exposed to fentanyl compared to men. These findings highlight the urgent need to further understand experiences of gender-based risk differences and develop gender-focused interventions and policies aimed at preventing drug-related harm.

Impact of overdose prevention sites during a public health emergency in Victoria, Canada

The primary objective of this study was to examine the impacts associated with implementation of overdose preventions sites (OPSs) in Victoria, Canada during a declared provincial public health overdose emergency. A rapid case study design was employed with three OPSs constituting the cases. Data were collected through semi-structured interviews with 15 staff, including experiential staff, and 12 service users. Theoretically, we were informed by the Consolidated Framework for Implementation Research. This framework, combined with a case study design, is well suited for generating insight into the impacts of an intervention. Zero deaths were identified as a key impact and indicator of success. The implementation of OPSs increased opportunities for early intervention in the event of an overdose, reducing trauma for staff and service users, and facilitated organizational transitions from provision of safer supplies to safer spaces. Providing a safer space meant drug use no longer needed to be concealed, with the effect of mitigating drug related stigma and facilitating a shift from shame and blame to increasing trust and development of relationships with increased opportunities to provide connections to other services. These impacts were achieved with few new resources highlighting the commitment of agencies and harm reduction workers, particularly those with lived experience, in achieving beneficial impacts. Although mitigating harms of overdose, OPSs do not address the root problem of an unsafe drug supply. OPSs are important life-saving interventions, but more is needed to address the current contamination of the illicit drug supply including provision of a safer supply.

Practices of care among people who buy, use, and sell drugs in community settings

BACKGROUND

Popular perception of people who sell drugs is negative, with drug selling framed as predatory and morally reprehensible. In contrast, people who use drugs (PWUD) often describe positive perceptions of the people who sell them drugs. The "Satellite Sites" program in Toronto, Canada, provides harm reduction services in the community spaces where people gather to buy, use, and sell drugs. This program hires PWUD-who may move into and out of drug selling-as harm reduction workers. In this paper, we examine the integration of people who sell drugs directly into harm reduction service provision, and their practices of care with other PWUD in their community.

METHODS

Data collection included participant observation within the Satellite Sites over a 7-month period in 2016-2017, complemented by 20 semi-structured interviews with Satellite Site workers, clients, and program supervisors. Thematic analysis was used to examine practices of care emerging from the activities of Satellite Site workers, including those circulating around drug selling and sharing behaviors.

RESULTS

Satellite Site workers engage in a variety of practices of care with PWUD accessing their sites. Distribution of harm reduction equipment is more easily visible as a practice of care because it conforms to normative framings of care. Criminalization, coupled with negative framings of drug selling as predatory, contributes to the difficultly in examining acts of mutual aid and care that surround drug selling as practices of care. By taking seriously the importance for PWUD of procuring good quality drugs, a wider variety of practices of care are made visible. These additional practices of care include assistance in buying drugs, information on drug potency, and refusal to sell drugs that are perceived to be too strong.

CONCLUSION

Our results suggest a potential for harm reduction programs to incorporate some people who sell drugs into programming. Taking practices of care seriously may remove some barriers to integration of people who sell drugs into harm reduction programming, and assist in the development of more pertinent interventions that understand the key role of drug buying and selling within the lives of PWUD.

The emergence of innovative cannabis distribution projects in the downtown eastside of Vancouver, Canada

The ongoing overdose crisis in the United States and Canada has highlighted the urgent need for innovative interventions to reduce drug-related harms. This, in turn, has led to increased interest in the potential of cannabis as a harm reduction strategy. While Canada has recently legalized cannabis, meaningful barriers to accessing legal cannabis remain for people who use drugs (PWUD) from marginalized communities. In the Downtown Eastside of Vancouver, Canada, innovative, grassroots cannabis distribution programs that dispense cannabis and cannabis products from unregulated sources to PWUD for free have recently emerged. In this study, we draw upon 23 in-depth qualitative interviews and ethnographic fieldwork with PWUD who access these programs. We found that these distribution programs play an important function in bridging access to cannabis for PWUD in a structurally disadvantaged neighborhood and do so by implementing few restrictions on who can access, providing a variety of cannabis products that would otherwise be inaccessible, and distributing cannabis at no cost. In addition, many people reported the program spaces provided an avenue to socialize and connect. Most of our participants reported that legal cannabis was inaccessible both through the legal medical and non-medical systems. Considering Canadian governments have made important regulatory changes in regards to cannabis, understanding emerging patterns and the structural barriers to accessing legal cannabis will be critical to maximizing the potential uses of cannabis as a harm reduction tool and ensuring equitable access to structurally disadvantaged populations. Examining the impact of cannabis use on PWUD and ensuring these groups have access to cannabis is an important component in determining whether cannabis deregulation reduces drug-related harms.

Supervised injection facility use and exposure to violence among a cohort of people who inject drugs: A gender-based analysis

BACKGROUND

Supervised injection facilities (SIFs) have been established in many settings, in part to reduce risks associated with injecting in public, including exposure to violence. However, the relationship between SIF use and experiencing violence has not yet been thoroughly evaluated. We sought to longitudinally examine the gender-specific relationship between SIF use and exposure to violence among people who inject drugs (PWID) in a Canadian setting.

METHODS

Data were drawn from two prospective cohort studies of PWID in Vancouver, Canada, between December 2005 and December 2016. Semi-annually, participants completed questionnaires that elicited data concerning sociodemographic characteristics, behavioural patterns, violent encounters and health service utilization. We used multivariable generalized estimating equations (GEE) to estimate the independent association between exclusively injecting drugs at a SIF and experiencing physical or sexual violence among men and women PWID, respectively.

RESULTS

Of 1930 PWID followed for a median of four years, 679 (35.2%) were women and the median age was 41 years at baseline. In total, 353 (52.0%) women and 694 (55.5%) men reported experiencing at least one incident of violence during follow-up. In multivariable analyses, exclusive SIF use was associated with decreased odds of experiencing violence among men after adjusting for potential confounders (Adjusted Odds Ratio [AOR] = 0.64; 95% confidence interval [CI]: 0.46-0.89). Exclusive SIF use was not significantly associated with experiencing violence among women in adjusted analyses (AOR = 0.97; 95% CI: 0.57-1.66).

CONCLUSION

In light of the recent expansion of SIFs in Canada, our finding of a protective association between exclusive SIF use and exposure to violence among men is encouraging. The fact that we did not observe a significant association between SIF use and experiencing violence among women highlights the need for social-structural interventions that are more responsive to the specific needs of women PWID in relation to violence prevention.

Factors Associated With the Use of Supervised Consumption Facilities Among Women Who Inject Drugs in a Canadian Setting

BACKGROUND

Supervised consumption facilities (SCFs) are evidence-based harm reduction interventions that have been shown to reduce the risk of social and health-related harms associated with injection drug use. Previous qualitative studies have highlighted important motivations for SCF use among women who use drugs. However, factors associated with SCF use among women have not previously been evaluated.

METHODS

Data were obtained from 2 longitudinal community-recruited cohorts of people who use drugs in Vancouver, Canada between 2003 and 2017. Multivariable generalized estimating equations were used to calculate the odds of SCF use associated with social and structural risk factors for drug-related harm among women who reported injection drug use in the preceding 6-months.

RESULTS

A total of 795 participants were included in the study, contributing to 6302 interviews, with 602 participants (76%) reporting SCF use in at least one interview. Multivariable analysis demonstrated daily heroin and crystal methamphetamine injection (Adjusted Odds Ratio [AOR] = 1.32 and 1.65, respectively), injecting in public (AOR = 1.77), binge injection (AOR = 1.22) and lack of housing (AOR = 1.74) to be associated with SCF use.

CONCLUSIONS

The current study demonstrates higher intensity patterns of drug use, including daily heroin and crystal methamphetamine injection, injecting in public and binge injection, as well as homelessness to be associated with SCF use among women. Future research should identify barriers to SCF use among women to minimize the risk of overdose and other drug-related harms.
