Repurposing prescribed hydromorphone: Alternative uses of safer supply and tablet-injectable opioid agonist treatment to meet unaddressed health needs

BACKGROUND

In response to the ongoing overdose crisis in Canada, a number of opioid agonist treatment and safer supply programs provide people at high overdose risk with daily-dispensed tablet hydromorphone, with some requiring witnessed ingestion and others providing take-away doses. While these programs are intended to reduce overdose events by limiting people's use of the contaminated drug supply, the experiences of people receiving hydromorphone vary. In this article we explore the ways people repurpose hydromorphone to address unmet needs.

METHODS

This article draws on in-depth qualitative interviews from two studies evaluating hydromorphone tablet distribution programs in British Columbia, Canada. We used thematic analysis to identify themes related to repurposing hydromorphone. We compared themes across the two studies to identify any similarities or differences in relation to the ways study participants discussed repurposing hydromorphone tablets. We utilize vignettes - snapshots of participant experiences - to analyse and represent the data.

RESULTS

Four vignettes demonstrate how hydromorphone tablets are often being used to address and resolve unmet needs of people who use drugs. While most participants reported reducing their use of illicit drugs, a variety of instrumental uses of tablet hydromorphone were also discussed, including reducing anxiety, addressing sleep issues, withdrawal management, and managing chronic pain.

CONCLUSION

Our findings demonstrate how people who use drugs are maximizing the benefits of tablet hydromorphone distribution to address unmet needs. Hydromorphone distribution programs represent a public health and harm reduction intervention that is usefully addressing experiences related to structural vulnerabilities (such as inadequate pain management), which are often overlooked amongst stigmatized groups.

Xylazine's Impacts on the Community in Philadelphia: Perspectives of People Who Use Opioids and Harm Reduction Workers

BACKGROUND

Xylazine is in 99% of the fentanyl supply in Philadelphia, PA and is on the rise throughout the United States. Perspectives about this emerging crisis among people who use opioids (PWUO) and harm reduction workers are lacking.

METHODS

We conducted focus groups with PWUO and harm reduction workers in Philadelphia, PA. Discussions focused on xylazine's impact on PWUO. Transcripts were coded for thematic analysis.

RESULTS

Themes across focus groups included xylazine withdrawal, wounds, safety concerns, and overdose response implications. Participants emphasized extreme xylazine withdrawal and the difficulty of withdrawal management. Groups explored potential roles of first responders in addressing xylazine-related wounds. PWUO were receptive to receiving help, but many harm reduction workers expressed reservations about partnering with police.

DISCUSSION

Results underscore the impact of xylazine withdrawal on PWUO. Emerging information on withdrawal management should be shared among care providers to identify optimal protocols. Safety-planning with PWUO should be explored, but structural interventions are imperative. While there may be a role for first responders in delivering harm reduction interventions, it is important to recognize historical harms by first responders against PWUO.

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.

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.

Accessibility gaps of physical supervised consumption sites in Canada motivating the use of overdose response technology/phone based virtual overdose response services: a retrospective cohort study

Background

Overdose response technology or virtual overdose response services are an evolving complementary harm reduction intervention which may overcome certain accessibility barriers of physical supervised consumption sites (SCS) and overdose prevention sites (OPS). We sought to characterize SCS/OPS accessibility barriers among clients accessing a nationwide overdose response phone-based hotline in Canada.

Methods

We performed a retrospective cohort analysis using anonymized call logs of the National Overdose Response Service (NORS) between December 2020 to July 2023. De-identified caller locations were cross-referenced with the locations, policies and operational hours of existing physical SCS/OPS. The primary outcome was accessibility of physical SCS/OPS defined hierarchically according to alignment with caller postal code, substance use routes reported, and calling times.

Findings

Our cohort comprised 4501 calls from 331 unique clients. Despite always having nearby SCS/OPS open and supporting substance use routes of choice, 100 clients (30.2%) preferentially utilized NORS. Among 191 clients (57.7%) who never had access to physical SCS/OPS at time of calling, 92 (27.8%) lacked a nearby site, 58 (17.5%) called outside of operational hours, and 41 (12.4%) would not be permitted to smoke on premises. Secondary analyses identified correlations between accessibility and the urbanicity and geographical region of callers within Canada.

Interpretation

Overdose response technology or virtual overdose response services are a novel complementary harm reduction strategy both for clients with access barriers to physical SCS/OPS and those who prefer virtual services. System-level correlates of client location urbanicity and inter-provincial variation indicate actionable targets for expanding harm reduction services both physical and virtual to better engage with people who use drugs.

A qualitative study on perceptions and experiences of overdose among people who smoke drugs in Vancouver, British Columbia

BACKGROUND

Smoking unregulated drugs has increased substantially in British Columbia. Intersecting with the ongoing overdose crisis, drug smoking-related overdose fatalities have correspondingly surged. However, little is known about the experiences of overdose among people who smoke drugs accessing the toxic drug supply. This study explores perceptions and experiences of overdose among people who smoke drugs.

METHODS

We conducted interviews with 31 people who smoke drugs. Interviews covered a range of topics including overdose experience. Thematic analysis was used to identify themes related to participant perceptions and experiences of smoking-related overdose.

RESULTS

Some participants perceived smoking drugs to pose lower overdose risk relative to injecting drugs. Participants reported smoking-related overdose experiences, including from underestimating the potency of drugs, the cross-contamination of stimulants with opioids, and responding to smoking-related overdose events.

CONCLUSIONS

Findings highlight the impact the unpredictable, unregulated, and toxic drug supply is having on people who smoke drugs, both among people who use opioids, and among those who primarily use stimulants. Efforts to address smoking-related overdose could benefit from expanding supervised smoking sites, working with people who use drugs to disseminate accurate knowledge around smoking-related overdose risk, and offering a smokable alternative to the unpredictable drug supply.

"If you're strung out and female, they will take advantage of you": A qualitative study exploring drug use and substance use service experiences among women in Boston and San Francisco

BACKGROUND

Significant disparities in substance use severity and treatment persist among women who use drugs compared to men. Thus, we explored how identifying as a woman was related to drug use and treatment experiences.

METHODS

The study recruited participants for a qualitative interview study in Boston and San Francisco from January-November 2020. Self-identified women, age ≥ 18 years, with nonprescribed opioid use in the past 14 days were eligible for inclusion. The study team developed deductive codes based on intersectionality theory and inductive codes generated from transcript review, and identified themes using grounded content analysis.

RESULTS

The study enrolled thirty-six participants. The median age was 46; 58 % were White, 16 % were Black, 14 % were Hispanic, and 39 % were unstably housed. Other drug use was common with 81 % reporting benzodiazepine, 50 % cocaine, and 31 % meth/amphetamine use respectively. We found that gender (i.e., identifying as a woman) intersected with drug use and sex work practices and exacerbated experiences of marginalization. Violence was ubiquitous in drug use environments. Some women reported experiences of gender-based violence in substance use service settings that perpetuated cycles of trauma and reinforced barriers to care. Substance use services that were women-led, safe, and responsive to women's needs were valued and sought after.

CONCLUSION

Women reported a cycle of trauma and drug use exacerbated by oppression in substance use services settings. In addition to increasing access to gender-responsive care, our study highlights the need for greater research and examination of practices within substance use service settings that may be contributing to gender-based violence.

"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).

Association of sex work and social-structural factors with non-fatal overdose among women who use drugs in Vancouver, Canada

BACKGROUND

Women who use drugs (WWUD) and engage in sex work experience disproportionate sex- and drug-related harms, such as HIV, however comparatively little is known about their overdose risk. Therefore, we examined the association between sex work and overdose and secondarily explored the association of social-structural factors, such as policing and gendered violence, with overdose.

METHODS

Data were derived from two community cohort studies based in Vancouver, Canada between 2005 to 2018. We used logistic regression with GEE to examine the associations between a) sex work and nonfatal overdose and b) social-structural and individual variables with overdose among WWUD who engaged in sex work during the study. Sex work, overdose, and other variables were time-updated, captured every six months.

RESULTS

Among 857 WWUD included, 56% engaged in sex work during the study. Forty-three percent of WWUD engaged in sex work had at least one overdose compared to 26% of WWUD who did not. Sex work was not significantly associated with an increased odds of overdose (AOR = 1.14, 95% CI: 0.93-1.40). In the exploratory analysis amongst 476 WWUD engaged in sex work, social-structural variables associated with overdose in the multivariable model included exposure to: punitive policing (OR = 1.97, 95% CI: 1.30-2.96) and physical or sexual violence (OR = 2.55, 95% CI: 1.88-3.46).

CONCLUSIONS

WWUD engaged in sex work had an increased overdose burden that may be driven by social-structural factors rather than sex work itself. Interventions that address policing and gendered violence represent potential targets for effective overdose prevention.

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.

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.

Drug Consumption Rooms: Welfare State and Diversity in Social Acceptance in Denmark and in France

Drug consumption rooms (DCRs) have the potential to have a positive impact on the opioid overdose crisis. DCRs could also potentially change the political environment for public health because they can affect the distribution of responsibility for harm reduction between the individual and society by collectivizing responsibility for harm reduction through welfare regimes. The methodology is based on 2 case studies-1 in Copenhagen, Denmark, and 1 in Paris, France-about residents, people who inject drugs (PWID), and politicians' experiences of DCRs involving semidirective interviews. Denmark has a long history of harm-reduction policy, and the implementation of DCRs in Copenhagen has happened through close collaboration between local authorities and the local community. France is far more centralized and paternalistic in terms of the distribution of authority and decision-making in welfare and drug policy. Difficulties in cohabitation between local residents and PWID happened in both countries and can sometimes make public authorities hesitate to implement DCRs because of the NIMBY ("not in my backyard") phenomenon. However, the Danish and French case studies show that DCRs have the potential to become an instrument for civic cohabitation as well as to contribute to the destigmatization and health of PWID.

Gender Dynamics in Substance Use and Treatment: A Women's Focused Approach

Gender impacts substance use initiation, substance use disorder development, engagement with treatment, and harms related to drug and alcohol use. Using the biopsychosocial model of addiction, this review provides a broad summary of barriers and facilitators to addiction services among women. It also reviews substance use among pregnant and parenting women and approaches to care. Given the increasing rates of substance use among women, there is a need to implement and scale-up gender-responsive addiction programming and pursue advocacy at the policy level that addresses the root drivers of substance use inequities among women.

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.

Association of skin infections with sharing of injection drug preparation equipment among people who inject drugs

BACKGROUND

Sharing needles and injection drug preparation equipment (IDPE) among people who inject drugs (PWID) are well-established risk factors for viral transmission. Shared needles and IDPE may serve as bacterial niduses for skin and soft tissue infections (SSTI). Given the rising rates of SSTI in PWID, we investigated the association of needle and IDPE sharing on incidence of SSTI in a cohort of PWID.

METHODS

Inpatient PWID (N = 252) were recruited to a randomized controlled trial of an intervention aimed at reducing infections. The primary outcome was self-reported incidence of SSTI one-year post-hospitalization. In this secondary analysis, we assessed two variables: 1) sharing of IDPE alone, 2) sharing needles with or without IDPE, and compared these groups separately to persons who reported no sharing of needles or IDPE via a mixed-effects negative binomial regression model to estimate the effect of baseline sharing behavior on SSTI during follow-up via incidence rate ratios (IRR).

RESULTS

Participant characteristics: 38 years [mean], 58% male, 60% White, 90% primarily injected opioids, 1.58 (± 2.35) mean SSTI in the year prior to baseline. In terms of sharing behavior, 29% didn't share needles or IDPE, 13% shared IDPE only, and 58% shared needles with or without IDPE three months prior to baseline. After adjusting for co-variables, PWID who shared IDPE alone had a 2.2 fold higher IRR of SSTI (95%CI 1.27; 3.85, p = 0.005) and PWID who shared needles with or without IDPE had a 3.31 fold higher IRR of SSTI (95%CI 2.04; 5.37, p < 0.001), compared to those who did not share any equipment. The number of SSTI at baseline was associated with an IRR of 1.20 of SSTI during follow-up (95%CI 1.09; 1.32, p < 0.001).

CONCLUSIONS

In this cohort of hospitalized PWID, we found a significant association between baseline sharing of IDPE alone and of sharing of needles with or without IDPE with one-year incidence of SSTI.

Competing risks of women and men who use fentanyl: "The number one thing I worry about would be my safety and number two would be overdose"

BACKGROUND

Standard public health approaches to risk communication do not address the gendered dynamics of drug use. The aim of this study was to explore perceptions of fentanyl-related risks among women and men to inform future risk communication approaches.

METHODS

We conducted a qualitative study, purposively sampling English-speaking women and men, aged 18-25 or 35+ years, with past 12-month illicitly manufactured fentanyl use. In-depth individual interviews explored experiences of women and men related to overdose and fentanyl use. We conducted a grounded content analysis examining specific codes related to overdose and other health or social risks attributed to drug use. Using a constant comparison technique, we explored commonalities and differences in themes between women and men.

RESULTS

The study enrolled twenty-one participants, 10 women and 11 men. All participants had personal overdose experiences. Both women and men described overdosing as a "chronic" condition and expressed de-sensitization to the risk of overdose. Women and men described other risks around health, safety, and state services that often superseded their fear of overdose. Women feared physical and sexual violence and prioritized caring for children and maintaining relations with child protective services, while men feared violence arising from obtaining and using street drugs and incarceration. Only women reported that fear of violence prevented their utilization of harm reduction services.

CONCLUSIONS

Experiences with overdose and risk communication among people who use fentanyl-containing opioids varied by gender. The development of gender-responsive programs that address targeted concerns may be an avenue to enhance engagement with harm reduction and treatment services and create safe spaces for women not currently accessing available services.

A gender comparative analysis of post-traumatic stress disorder among a community-based cohort of people who use drugs in Vancouver, Canada

BACKGROUND

While exposure to traumatic events and subsequent post-traumatic stress disorder (PTSD) are common among people who use drugs (PWUD), little is known about gender-based differences associated with PTSD in this population. We explore gender-based differences in factors associated with a probable PTSD diagnosis in a cohort of PWUD from Vancouver, Canada.

METHODS

Data were collected through the Vancouver Injection Drug Users Study (VIDUS) and the AIDS Care Cohort to Evaluate Exposure to Survival Services (ACCESS), two community-recruited cohorts of PWUD. Participants were administered the PTSD Checklist for DSM-5. Multivariable logistic regression was used to investigate social-structural factors and substance use patterns and behaviours associated with a probable PTSD diagnosis, stratified by self-identified gender. PTSD symptom clusters and brief descriptions of the worst traumatic event experienced were also reported.

RESULTS

Between December 2016 and December 2018, of 797 eligible participants, 295 (37.0%) identified as women. PTSD was more commonly reported in women compared to men (53.2% vs. 31.5%, p < 0.001). In multivariable analysis involving men, no correlates were associated with PTSD. In multivariable analysis involving women, PTSD was positively associated with exposure to violence (AOR: 3.66; 95%CI: 1.14-11.72), daily stimulant use (AOR: 2.32; 95%CI: 1.32-4.08) and heavy alcohol use (AOR: 3.84; 95%CI: 1.84-8.00), and negatively associated with being in a stable relationship (AOR: 0.46; 95%CI: 0.25-0.84).

CONCLUSIONS

Gender-based differences in PTSD diagnosis among a cohort of PWUD point to the need to develop gender-focused and trauma-informed health and social services to meet the immediate needs of PWUD living with PTSD.

Hoots and harm reduction: a qualitative study identifying gaps in overdose prevention among women who smoke drugs

BACKGROUND

Smoking or inhaling illicit drugs can lead to a variety of negative health outcomes, including overdose. However, most overdose prevention interventions, such as supervised consumption services (SCS), prohibit inhalation. In addition, women are underrepresented at SCS and are disproportionately impacted by socio-structural violence. This study examines women's experiences smoking illicit drugs during an overdose epidemic, including their utilization of a women-only supervised inhalation site.

METHODS

Qualitative research methods included on-site ethnographic observation and semi-structured interviews with 32 participants purposively recruited from the women-only site. Data were coded and analyzed using NVivo 12 and thematic analysis was informed by gendered and socio-structural understandings of violence.

RESULTS

Participants had preferences for smoking drugs and these were shaped by their limited income, inability to inject, and perceptions of overdose risk. Participants expressed the need for services that attend to women's specific experiences of gendered, race-based, and structural violence faced within and outside mixed-gender social service settings. Results indicate a need for sanctioned spaces that recognize polysubstance use and drug smoking, accommodated by the women-only SCS. The smoking environment further fostered a sociability where participants could engage in perceived harm reduction through sharing drugs with other women/those in need and were able to respond in the event of an overdose.

CONCLUSIONS

Findings demonstrate the ways in which gendered social and structural environments shape women's daily experiences using drugs and the need for culturally appropriate interventions that recognize diverse modes of consumption while attending to overdose and violence. Women-only smoking spaces can provide temporary reprieve from some socio-structural harms and build collective capacity to practice harm reduction strategies, including overdose prevention. Women-specific SCS with attention to polysubstance use are needed as well as continued efforts to address the socio-structural harms experienced by women who smoke illicit drugs.

Between Emergency Department Visits: The Role of Harm Reduction Programs in Mitigating the Harms Associated With Injection Drug Use

Injection drug use is a major public health problem in the United States. Cocaine, heroin, and methamphetamine are the most commonly injected illicit drugs, whereas opioids are responsible for the majority of overdose fatalities. Although recent emergency department (ED) efforts have focused on expanding capacity for buprenorphine induction for opioid use disorder treatment, the injection of illicit drugs carries specific health risks that require acknowledgment and management, particularly for patients who decline substance use treatment. Harm reduction is a public health approach that aims to reduce the harms associated with a health risk behavior, short of eliminating the behavior itself. Harm-reduction strategies fundamental to emergency medicine include naloxone distribution for opioid overdose. This clinical Review Article examines the specific health complications of injection drug use and reviews the evidence base for 2 interventions effective in reducing morbidity and mortality related to drug injection, irrespective of the specific drug used, that are less well known and infrequently leveraged by emergency medicine clinicians: syringe service programs and supervised injection facilities. In accordance with the recommendations of health authorities such as the Centers for Disease Control and Prevention, emergency clinicians can promote the use of harm-reduction programs in the community to reduce viral transmission and other risks of injection drug use by providing patients with information about and referrals to these programs after injection drug use-related ED visits.

[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.

Convenience and comfort: reasons reported for using drugs alone among clients of harm reduction sites in British Columbia, Canada

Background

North American communities are severely impacted by the overdose crisis, particularly in British Columbia (BC), which has the highest toxic drug overdose death rate in Canada. Most fatal overdoses in BC occurred among individuals using alone and in private residences. This study aimed to assess prevalence and reasons for using drugs alone among people accessing harm reduction services in BC.

Methods

We recruited harm reduction supply distribution site clients from 22 communities across BC. Descriptive statistics and multivariable logistic regression were used to describe factors associated with using alone. Thematic analysis of free-text responses providing reasons for using alone were grouped with survey data and additional themes identified.

Results

Overall, 75.8% (n = 314) of the study sample (N = 414) reported using drugs alone within the last week. Those that reported using alone did not differ from those that did not by gender, age, urbanicity, or preferred drug use method. Among those that used alone, 73.2% (n = 230) used opioids, 76.8% (n = 241) used crystal meth, 41.4% (n = 130) used crack/cocaine, and 44.6% (n = 140) used alcohol in the past week. Polysubstance use involving stimulants, opioids, and/or benzodiazepines was reported by 68.5% (n = 215) of those that used alone. Additionally, 22.9% (n = 72) of those that used alone had experienced an opioid and/or stimulant overdose in the past 6 months. In a multivariable logistic regression model, having no regular housing and past week crack/cocaine use were associated with using alone (adjusted odds ratio (AOR): 2.27; 95% CI 1.20–4.27 and AOR: 2.10; 95% CI 1.15–3.82, respectively). The most common reason reported for using alone was convenience and comfort of using alone (44.3%). Additional reasons included: stigma/hiding drug use (14.0%); having no one around (11.7%); safety (9.6%); and not wanting to share drugs with others (8.6%).

Conclusions

Using drugs alone, particularly for convenience and comfort, is ubiquitous among people accessing harm reduction services. Overdose prevention measures that go beyond individual behaviour changes, including providing a safer supply of drugs and eliminating stigma, are paramount to mitigate harms. These interventions are especially necessary as emergence of coronavirus disease may further exacerbate unpredictability of illicit drug content and overdose risk.

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.

High willingness to use overdose prevention sites among female sex workers in Baltimore, Maryland

BACKGROUND

Overdose Prevention Sites (OPS) operate worldwide as spaces where people can consume previously purchased drugs under supervision, and are linked to reductions in HIV/HCV transmission and fatal overdoses. As the United States weighs their merits and legality, research is needed to estimate acceptability and use among populations at high risk for overdose. We examine willingness to use OPS among street-based female sex workers (FSW) with prevalent drug use and associated morbidities.

METHODS

We describe self-reported willingness, barriers and conditions around use of a hypothetical OPS among 141 FSW engaged in active drug use in Baltimore City, and describe trends using Pearson's χ2 and Fisher's exact tests.

RESULTS

Most women had history of overdose (55 %) and were likely to use OPS (77 %). Willingness was higher among women who: were sexual minorities (97 %;P=0.002),experienced homelessness (82 %;P=0.019), injected drugs (82 %;P=0.013), shared syringes (82 %;P=0.007), experienced sexual violence (92 %;P=0.045) or reported heroin use (83 %;P=0.039) in the past 3 months. Common anticipated barriers included transportation (45 %) and fear of arrest (41 %).

CONCLUSIONS

This study highlights a population of uniquely high-risk women who would benefit from an OPS integrated with other services. Conditions and barriers discussed are informative for planning and implementation.

"It's not just injecting drugs": Supervised consumption sites and the social determinants of health

BACKGROUND

People who inject drugs are highly vulnerable to social determinants of health (SDOH) inequities, such as homelessness, food insecurity, lack of social support, and poor access to healthcare. Supervised consumption sites (SCSs) have been developed to reduce harms associated with injection drug use but their social impacts remain largely unknown. This study explored service users' experiences with SCSs and how their service use affected their SDOH.

METHODS

A qualitative descriptive study design was used. Participants were recruited from an SCS in Ottawa, Canada. Data were collected using in-depth interviews (n = 21). Data analysis involved two cycles of coding that were visibly presented in an analytic matrix. Member checking of the findings was then completed using two focus groups (n = 7).

RESULTS

Five themes were identified with regard to how SCSs impacted the SDOH: (1) social connectedness and community, (2) emotional support and stress reduction, (3) safety and security, (4) current shelter statuses and search for housing, and (5) health service access and use. The perceived effects of SCSs in these domains were mostly positive, though the importance of being vigilant and cautious when using the services was also expressed by participants.

CONCLUSIONS

SCSs represent a potential downstream intervention to addressing some of the SDOH inequities experienced by people who inject drugs. In particular, the findings indicate that SCSs can be a bridge to rebuilding service users' connections with the healthcare system and an important service in efforts to prevent unsheltered homelessness.

"Bed Bugs and Beyond": An ethnographic analysis of North America's first women-only supervised drug consumption site

BACKGROUND

Attention to how women are differentially impacted within harm reduction environments is salient amidst North America's overdose crisis. Harm reduction interventions are typically 'gender-neutral', thus failing to address the systemic and everyday racialized and gendered discrimination, stigma, and violence extending into service settings and limiting some women's access. Such dynamics highlight the significance of North America's first low-threshold supervised consumption site exclusively for women (transgender and non-binary inclusive), SisterSpace, in Vancouver, Canada. This study explores women's lived experiences of this unique harm reduction intervention.

METHODS

Ethnographic research was conducted from May 2017 to June 2018 to explore women's experiences with SisterSpace in Vancouver's Downtown Eastside, an epicenter of Canada's overdose crisis. Data include more than 100 hours of ethnographic fieldwork, including unstructured conversations with structurally vulnerable women who use illegal drugs, and in-depth interviews with 45 women recruited from this site. Data were analyzed in NVivo by drawing on deductive and inductive approaches.

FINDINGS

The setting (non-institutional), operational policies (no men; inclusive), and environment (diversity of structurally vulnerable women who use illegal drugs), constituted a space affording participants a temporary reprieve from some forms of stigma and discrimination, gendered and social violence and drug-related harms, including overdose. SisterSpace fostered a sense of safety and subjective autonomy (though structurally constrained) among those often defined as 'deviant' and 'victims', enabling knowledge-sharing of experiences through a gendered lens.

CONCLUSION

SisterSpace demonstrates the value and effectiveness of initiatives that engage with socio-structural factors beyond the often narrow focus of overdose prevention and that account for the complex social relations that constitute such initiatives. In the context of structural inequities, criminalization, and an overdose crisis, SisterSpace represents an innovative approach to harm reduction that accounts for situations of gender inequality not being met by mixed-gender services, with relevance to other settings.

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.

Women's utilization of housing-based overdose prevention sites in Vancouver, Canada: An ethnographic study

BACKGROUND

In response to a fentanyl-driven overdose crisis, low-threshold supervised consumption sites, termed overdose prevention sites (OPS), have been rapidly implemented in Vancouver, Canada. Since approximately 88% of fatal overdoses in the province occur indoors, OPS have been integrated into select non-profit-operated single room accommodations (SRA) housing. We examined the social-structural features of these housing-based OPS (HOPS) on women's overdose risk.

METHODS

Ethnographic research was conducted from May 2017 to December 2018 in Vancouver. Data included 35 in-depth interviews with women who use drugs living in SRAs and approximately 100 h of observational fieldwork in SRAs and surrounding areas. Data were analyzed using an intersectional risk environment approach, with attention to equity and violence.

FINDINGS

Findings demonstrate that the social and structural environments of HOPS created barriers for women to access these interventions, resulting in an increased overdose risk. Primary barriers included uncertainty as to who else was accessing HOPS, rules prohibiting smoking, and a lack of trust in staff's abilities to effectively respond to an overdose. Most participants considered HOPS to be unsafe environments, and expressed fear of violence from residents and/or guests. The perceived risk of violence was informed by previous experiences of assault and the witnessing of violence. Many participants thus consumed drugs alone in their rooms to better control their safety, despite heightened overdose risk. Further, most participants did not perceive themselves to be at risk of an overdose due to drug use practices and tolerance levels, and viewed using alone as a safer option than HOPS.

CONCLUSION

Findings highlight how the low-barrier design and operation of HOPS can undermine women's engagement with HOPS. Overdose prevention strategies in SRAs should also include gender-specific models (e.g. women-only HOPS, women peer workers) to help mitigate barriers to these services within the context of the current overdose crisis.

Police-related barriers to harm reduction linked to non-fatal overdose amongst sex workers who use drugs: Results of a community-based cohort in Metro Vancouver, Canada

BACKGROUND

High rates of overdose and overdose-related mortality in North America represent a pressing health and social concern. Women sex workers face severe health and social inequities, which have been linked to structural factors including negative police interactions; however, little is known regarding the burden of overdose or how policing impacts overdose risk amongst sex workers who use drugs. Given this, we aimed to explore the independent effects of experiencing police-related barriers to harm reduction on non-fatal overdose amongst women sex workers who use drugs in Metro Vancouver, Canada over a 7.5-year period.

METHODS

Data were drawn from An Evaluation of Sex Workers Health Access (AESHA), a community-based open prospective cohort of women sex workers in Metro Vancouver, from 2010 to 2017. Using multivariate logistic regression with generalized estimating equations (GEE), we used a confounder modeling approach to identify the independent effect of experiencing police-related barriers to harm reduction strategies on non-fatal overdose amongst sex workers using drugs within the last six months at each study visit.

RESULTS

Amongst 624 participants, 7.7% overdosed within the last six months at baseline and 27.6% overdosed during the study period, contributing 287 non-fatal overdose events over the 7.5-year period. 68.6% reported police-related barriers to harm reduction strategies during the study. In a multivariate confounder model, exposure to police-related barriers to harm reduction strategies [AOR: 2.15, CI: 1.60-2.90] was independently associated with higher odds of non-fatal overdose after adjustment for key confounders.

CONCLUSIONS

Our findings suggest that in the context of the current overdose crisis, adversarial policing practices may undermine access to lifesaving overdose prevention services and exacerbate overdose risks for marginalized women. Findings underscore the urgent need to scale-up access and remove barriers to progressive harm reduction strategies for women sex workers.

Policing space in the overdose crisis: A rapid ethnographic study of the impact of law enforcement practices on the effectiveness of overdose prevention sites

North America is in the midst of an overdose crisis. In some of the hardest hit areas of Canada, local responses have included the implementation of low-threshold drug consumption facilities, termed Overdose Prevention Sites (OPS). In Vancouver, Canada the crisis and response occur in an urban terrain that is simultaneously impacted by a housing crisis in which formerly 'undesirable' areas are rapidly gentrifying, leading to demands to more closely police areas at the epicenter of the overdose crisis. We examined the intersection of street-level policing and gentrification and how these practices re/made space in and around OPS in Vancouver's Downtown Eastside neighborhood. Between December 2016 and October 2017, qualitative interviews were conducted with 72 people who use drugs (PWUD) and over 200 h of ethnographic fieldwork were undertaken at OPS and surrounding areas. Data were analyzed thematically and interpreted by drawing on structural vulnerability and elements of social geography. While OPS were established within existing social-spatial practices of PWUD, gentrification strategies and associated police tactics created barriers to OPS services. Participants highlighted how fear of arrest and police engagement necessitated responding to overdoses alone, rather than engaging emergency services. Routine policing near OPS and the enforcement of area restrictions and warrant searches, often deterred participants from accessing particular sites. Further documented was an increase in the number of police present in the neighborhood the week of, and the week proceeding, the disbursement of income assistance cheques. Our findings demonstrate how some law enforcement practices, driven in part by ongoing gentrification efforts and buttressed by multiple forms of criminalization present in the lives of PWUD, limited access to needed overdose-related services. Moving away from place-based policing practices, including those driven by gentrification, will be necessary so as to not undermine the effectiveness of life-saving public health interventions amid an overdose crisis.

Implementation contexts and the impact of policing on access to supervised consumption services in Toronto, Canada: a qualitative comparative analysis

BACKGROUND

Supervised consumption services (SCS) are being implemented across Canada in response to a variety of drug-related harms. We explored the implementation context of newly established SCS in Toronto and the role of policing in shaping program access by people who inject drugs (PWID).

METHODS

We conducted one-to-one qualitative semi-structured interviews with 24 PWID. Participants were purposively recruited. Ethnographic observations were conducted at each of the study sites as well as in their respective neighbourhoods. Relevant policy documents were also reviewed.

RESULTS

Policing was overwhelmingly discussed by participants from both SCS sites. However, participant responses varied depending on the site in question. Subthemes from participant responses on policing at site #1 described neighbourhood police presence and fears of police harassment and drug arrests before, during, or after accessing SCS. Conversely, subthemes from participant responses on policing at site #2 described immunity and protection from police while using the SCS, as well as a lack of police presence or fears of police harassment and arrests. These differences in implementation contexts were largely shaped by differences in local neighbourhoods and drug scenes. Police policies highlighted federal laws protecting PWID within SCS, but also the exercise of discretion when applying the rule of law outside of these settings.

CONCLUSIONS

Participants' perspectives on, and experiences with, policing as they relate to accessing SCS were shaped by the implementation contexts of each SCS site and how neighbourhoods, drug scenes, and differences in policing practices affected service use. Our findings also demonstrate the disconnect between the goals of policing and those of SCS. Until larger structural barriers are addressed (e.g. criminalization), future SCS programming should consider the impact of policing on the SCS implementation context to improve client experience with, and access to, SCS.

Prevalence and correlates of selling illicit cannabis among people who use drugs in Vancouver, Canada: A ten-year prospective cohort study

BACKGROUND

The illicit selling and use of cannabis is prevalent among marginalized people who use illicit drugs (PWUD). Given that participation in illicit drug markets has been previously associated with a range of health and social harms, we sought to examine the predictors of selling cannabis among PWUD in Vancouver, Canada, a setting with a de facto legalized cannabis market, on the eve of the planned implementation of legalized non-medical cannabis including measures to regulate the existing illicit market.

METHODS

Multivariable generalized estimating equations (GEE) logistic regression was used to analyze longitudinal factors associated with selling illicit cannabis among three prospective cohorts of PWUD between September 2005 and May 2015.

RESULTS

Among the 3258 participants included in this study, 328 (10.1%) reported selling illicit cannabis at baseline, and 46 (5.1%) initiated cannabis selling over the study period. In the multivariable analysis of the whole sample, factors significantly associated with selling cannabis included cannabis use (Adjusted Odds Ratio [AOR] = 4.05), dealing other drugs (AOR = 3.87), being male (AOR = 1.83), experiencing violence (AOR = 1.40), non-medical prescription opioid use (AOR = 1.32), non-custodial involvement in the criminal justice system (AOR = 1.31), being stopped by police (AOR = 1.30), crack use (AOR = 1.25), homelessness (AOR = 1.23), age (AOR = 0.96 per year) and participation in sex work (AOR = 0.67) (all p < 0.05). The subanalyses indicated that dealing drugs other than cannabis, cannabis use, and non-custodial involvement in the criminal justice system were the only factors significantly associated with selling cannabis in all four subgroups.

CONCLUSION

These findings support existing evidence indicating that selling illicit cannabis is often a survival-driven strategy to support the basic needs and substance use of some PWUD. Our findings suggest jurisdictions with planned or impending cannabis legalization and regulation should consider the vulnerability of PWUD when seeking to eradicate illicit cannabis markets, for example, in setting criminal penalties for selling cannabis outside of regulatory frameworks.

Drug consumption rooms: A systematic review of evaluation methodologies

ISSUES

Drug consumptions rooms (DCR) and supervised injecting facilities (SIF) are expanding internationally. Previous reviews have not systematically addressed evaluation methodologies.

APPROACH

Results from systematic searches of scientific databases in English until June 2017 were coded for paper type, country and year of publication. For evaluation papers, study outcome, methodology/study design and main indicators of DCR/SIF 'exposure' were recorded.

KEY FINDINGS

Two hundred and nineteen eligible peer-reviewed papers were published since 1999: the majority from Canada (n = 117 papers), Europe (n = 36) and Australia (n = 32). Fifty-six papers reported evaluation outcomes. Ecological study designs (n = 10) were used to assess the impact on overdose, public nuisance and crime; modelling techniques (n = 6) estimated impact on blood-borne diseases, overdose deaths and costs. Papers using individual-level data included four prospective cohorts (n = 28), cross-sectional surveys (n = 7) and service records (n = 5). Individual-level data were used to assess safer injecting practice, uptake into health and social services and all the other above outcomes except for impact on crime and costs. Four different indicators of DCR/SIF attendance were used to measure service 'exposure'.

IMPLICATIONS

Research around DCRs/SIFs has used ecological, modelling, cross-sectional and cohort study designs. Further research could involve systematic inclusion of a control group of people who are eligible but do not access SIFs, validation of self-reported proportion of injections at SIFs or a stepped-wedge or a cluster trial comparing localities.

CONCLUSIONS

Methodologies appropriate for DCR/SIF evaluation have been established and can be readily replicated from the existing literature. Research on operational aspects, implementation and transferability is also warranted.

A systematic review of stakeholder perceptions of supervised injection facilities

INTRODUCTION

Supervised injection facilities (SIFs) have been developed to address the public health burden associated with substance use. While these facilities have been associated with a number of positive outcomes, stakeholder opinion (the opinions of those potentially affected by these facilities) is likely to influence their future development. This systematic review aims to answer the question, "how do stakeholders perceive SIFs?"

MATERIALS AND METHODS

Articles were located through nine academic databases, by searching for grey literature, by contacting health departments in countries where SIFs have been implemented, by searching articles that cited included articles, and by searching the reference lists of included articles. Two reviewers screened all articles. Data was double-extracted and quality appraised. All extracted perceptions were analyzed by two coders.

RESULTS

Forty-seven articles were synthesized. Key themes included (1) benefits of SIFs, such as the increased safety of people who use drugs (PWUD) and the education that was provided at these facilities; (2) concerns regarding SIFs, such as the location of these facilities and existing rules and regulations; and (3) suggestions for SIFs, such as changing restrictions and regulations. Perceptions often fluctuated between stakeholders with first-hand experience of SIFs (e.g. staff and PWUD) and stakeholders not involved in the operation of SIFs (e.g. the general public).

CONCLUSION

The findings of this review illustrate how perceptions vary and align across different types of SIFs. Going forward, it will be important to draw on these insights to facilitate a more informed discussion on the implementation and continuation of these facilities.

Potential use of supervised injection services among people who inject drugs in a remote and mid-size Canadian setting

BACKGROUND

While supervised injection services (SIS) feasibility research has been conducted in large urban centres across North America, it is unknown whether these services are acceptable among people who inject drugs (PWID) in remote, mid-size cities. We assessed willingness to use SIS and expected frequency of SIS use among PWID in Thunder Bay, a community in Northwestern, Ontario, Canada, serving people from suburban, rural and remote areas of the region.

METHODS

Between June and October 2016, peer research associates administered surveys to PWID. Sociodemographic characteristics, drug use and behavioural patterns associated with willingness to use SIS and expected frequency of SIS use were estimated using bivariable and multivariable logistic regression models. Design preferences and amenities identified as important to provide alongside SIS were assessed descriptively.

RESULTS

Among 200 PWID (median age, IQR: 35, 28-43; 43% female), 137 (69%) reported willingness to use SIS. In multivariable analyses, public injecting was positively associated with willingness to use (Adjusted Odds Ratio (AOR): 4.15; 95% confidence interval (CI): 2.08-8.29). Among those willing to use SIS, 87 (64%) said they would always/usually use SIS, while 48 (36%) said they would sometime/occasionally use SIS. In multivariable analyses, being female (AOR: 2.44; 95% CI: 1.06-5.65) and reporting injecting alone was positively associated with higher expected frequency of use (AOR: 2.59; 95% CI: 1.02-6.58).

CONCLUSIONS

Our findings suggest that SIS could play a role in addressing the harms of injection drug use in remote and mid-sized settings particularly for those who inject in public, as well as women and those who inject alone, who report higher expected frequency of SIS use. Design preferences of local PWID, in addition to differences according to gender should be taken into consideration to maximize the uptake of SIS, alongside existing health and social service provisions available to PWID.

The value of harm reduction for injection drug use: A clinical and public health ethics analysis

The US is facing dual public health crises related to opioid overdose deaths and HIV. Injection drug use is fueling both of these epidemics. The War on Drugs has failed to stem injection drug use and has contributed to mass incarceration, poverty, and racial disparities. Harm reduction is an alternative approach that seeks to decrease direct and indirect harms associated with drug use without necessarily decreasing drug consumption. Although overwhelming evidence demonstrates that harm reduction is effective in mitigating harms associated with drug use and is cost-effective in providing these benefits, harm reduction remains controversial and the ethical implications of harm reduction modalities have not been well explored. This paper analyzes harm reduction for injection drug use using the core principles of autonomy, nonmaleficence, beneficence, and justice from both clinical ethics and public health ethics perspectives. This framework is applied to harm reduction modalities currently in use in the US, including opioid maintenance therapy, needle and syringe exchange programs, and opioid overdose education and naloxone distribution. Harm reduction interventions employed outside of the US, including safer injection facilities, heroin-assisted treatment, and decriminalization/legalization are then discussed. This analysis concludes that harm reduction is ethically sound and should be an integral aspect of our nation's healthcare system for combating the opioid crisis. From a clinical ethics perspective, harm reduction promotes the autonomy of, prevents harms to, advances the well-being of, and upholds justice for persons who use drugs. From a public health ethics perspective, harm reduction advances health equity, addresses racial disparities, and serves vulnerable, disadvantaged populations in a cost-effective manner.

Gendered violence and overdose prevention sites: a rapid ethnographic study during an overdose epidemic in Vancouver, Canada

BACKGROUND AND AIMS

North America's overdose epidemic is increasingly driven by fentanyl and fentanyl-adulterated drugs. Supervised consumption sites, including low-threshold models (termed overdose prevention sites; OPS), are now being debated in the United States and implemented in Canada. Despite evidence that gendered and racialized violence shape access to harm reduction among women who use drugs (WWUD), this has not been examined in relation to OPS and amid the overdose epidemic. This study explores how overlapping epidemics of overdose and gendered and racialized violence in Vancouver's Downtown Eastside, one of North America's overdose epicenters, impacts how marginalized WWUD experience OPS.

DESIGN

Qualitative analysis using rapid ethnographic fieldwork. Data collection included 185 hours of naturalistic observation and in-depth interviews; data were analyzed thematically using NVivo.

SETTING

Vancouver, Canada.

PARTICIPANTS

Thirty-five WWUD recruited from three OPS.

MEASUREMENTS

Participants' experiences of OPS and the public health emergency.

FINDINGS

The rapid onset and severity of intoxication associated with the use of fentanyl-adulterated drugs in less regulated drug use settings not only amplified WWUD's vulnerability to overdose death but also violence. Participants characterized OPS as safer spaces to consume drugs in contrast to less regulated settings, and accommodation of assisted injections and injecting partnerships was critical to increasing OPS access among WWUD. Peer-administered injections disrupted gendered power relations to allow women increased control over their drug use; however, participants indicated that OPS were also gendered and racialized spaces that jeopardized some women's access.

CONCLUSION

Although women who use drugs in Vancouver, Canada appear to feel that overdose prevention sites address forms of everyday violence made worse by the overdose epidemic, these sites remain 'masculine spaces' that can jeopardize women's access.

Exploring what shapes injection and non-injection among a sample of marginalized people who use drugs

BACKGROUND

Few studies have specifically explored what influences people who use drugs to consume them in certain ways (i.e., smoking, injecting). While a great deal of research has examined the transition from non-injection to injection routes of drug administration, less is known about people who use drugs (PWUD) but have never injected or have stopped injecting. This paper draws on actor-network theory to explore what moves people to inject or not, among both people who currently smoke/sniff drugs (PWSD) and people who currently inject drugs (PWID), to better understand factors that shape/influence methods of drug consumption.

METHODS

Two-stage interviews (a quantitative survey followed by a qualitative interview) were conducted with 26 PWSD and 24 PWID. Interviews covered a range of topics related to drug use, including reasons for injecting drugs, never injecting, and stopping injecting. Data were analysed by drawing on actor-network theory to identify forces involved in shaping drug consumption practices.

RESULTS

We present three transformative drug use events to illustrate how specific methods of drug consumption are shaped by an assemblage of objects, actors, affects, spaces and processes. Rather than emphasising the role of broad socio-structural factors (i.e., poverty, drug policy) participant narratives reveal how a variety of actors, both human and non-human, assembled in unique ways produce drug consumption events that have the capacity to influence or transform drug consumption practices.

CONCLUSION

Actor-network theory and event analysis provide a more nuanced understanding of drug consumption practices by drawing together complex material, spatial, social and temporal aspects of drug use, which helps identify the variety of forces involved in contexts that are thought to shape substance use. By attending to events of drug consumption we can better understand how contexts shape drug use and related harms. With greater insight into the transformative capacity of drug use events, strategies may be better tailored to prevent drug use-related harms.

Residential eviction and exposure to violence among people who inject drugs in Vancouver, Canada

BACKGROUND

People who inject drugs (PWID) experience markedly elevated rates of physical and sexual violence, as well as housing instability. While previous studies have demonstrated an association between homelessness and increased exposure to violence among PWID, the relationship between residential eviction and violence is unknown. We therefore sought to examine the association between residential eviction and experiencing violence among PWID in Vancouver, Canada.

METHODS

Data were derived from two open prospective cohort studies of PWID: the Vancouver Injection Drug Users Study (VIDUS) and the AIDS Care Cohort to evaluate Exposure to Survival Services (ACCESS). We used generalized estimating equations (GEE) to estimate the relationship between residential eviction and experiencing violence among male and female PWID, respectively.

RESULTS

Between June 2007 and May 2014, 1689 participants were eligible for the analysis, contributing a median of 5.5 years of follow-up. Of these, 567 (33.6%) were female. In total, 259 (45.7%) of females and 566 (50.4%) of males experienced at least one incident of violence over the study period. In multivariable GEE models, residential eviction was independently associated with greater odds of experiencing violence among both females (Adjusted Odds Ratio [AOR]=2.09; 95% confidence interval [CI]: 1.39-3.13) and males (AOR=1.95; 95% CI=1.49-2.55), after adjustment for potential confounders.

CONCLUSION

Residential eviction was independently associated with an increased likelihood of experiencing violence among both male and female PWID. These findings point to the need for evidence-based social-structural interventions to mitigate housing instability and violence among PWID in this setting.

Changes in public order after the opening of an overdose monitoring facility for people who inject drugs

BACKGROUND

In the face of an increasingly fatal opioid crisis, Boston Health Care for the Homeless Program (BHCHP) opened the Supportive Place for Observation and Treatment (SPOT), a unique low-threshold harm reduction program for monitoring people who have injected drugs and are at imminent risk of overdose. This study examines the impact of the opening of the SPOT program on measures of injection drug-related public order in the neighborhood surrounding the facility.

METHODS

Data was collected at 10 weeks prior and 12 weeks post SPOT implementation on: number of over-sedated individuals in public, publicly discarded syringes, publicly discarded injection-related litter, and instances of active injection drug use or exchange of drugs. Changes were evaluated using Poisson log-linear regression models. Potential confounders such as weather and police presence were measured and controlled for.

RESULTS

The average number of over-sedated individuals observed in public significantly decreased by 28% (4.3 [95% Confidence Interval (CI) 2.7-6.9] v 3.1 [CI 1.4-6.8]) after SPOT opened. The opening of SPOT did not have a significant effect on the other measures of public order. The daily average number of publicly discarded syringes (28.5 [CI 24.5-33.1] v 28.4 [CI 22.0-36.5]), pieces of publicly discarded injection-related litter (376.3 [CI 358.6-394.8] v 375.0 [CI 345.8-406.6]), and observed instances of active use or exchange of drugs (0.2 [CI 0.1-0.9] v 0.1 [CI 0.0-0.1]) were not statistically significantly different after the opening of SPOT.

CONCLUSIONS

The opening of SPOT was associated with a significant decrease in observed over-sedated individuals. Other measures of injection-drug related public order did not improve or worsen with the opening of SPOT, however, they have been shown to improve with the implementation of a supervised injection facility.

Incidence and predictors of mental health disorder diagnoses among people who inject drugs in a Canadian setting

INTRODUCTION AND AIMS

Limited attention has been given to the predictors of mental health diagnoses among people who inject drugs (PWID) in community settings. Therefore, we sought to longitudinally examine the prevalence, incidence and predictors of mental disorder diagnosis among a community-recruited cohort of PWID.

DESIGN AND METHODS

Data were derived from two prospective cohort studies of PWID (VIDUS and ACCESS) in Vancouver, Canada between December 2005 and May 2015. We used multivariable extended Cox regression to identify factors independently associated with self-reported mental disorder diagnosis during follow-up among those without a history of such diagnoses at baseline.

RESULTS

Among the 923 participants who did not report a mental disorder at baseline, 206 (22.3%) reported a first diagnosis of a mental disorder during follow-up for an incidence density of 4.29 [95% confidence interval (CI) 3.72-4.91] per 100 person-years. In the multivariable analysis, female sex [adjusted hazards ratio (AHR) = 1.74, 95% CI 1.29-2.33], experiencing non-fatal overdose (AHR = 2.33, 95% CI 1.38-3.94), accessing any drug or alcohol treatment (AHR = 1.68, 95% CI 1.24-2.27), accessing any community health or social services (AHR = 1.53, 95% CI 1.02-2.28) and experiencing violence (AHR = 1.60, 95% CI 1.12-2.29) were independently associated with a mental disorder diagnosis at follow-up.

DISCUSSION AND CONCLUSIONS

We observed a high prevalence and incidence of mental disorders among our community-recruited sample of PWID. The validity and implication of these diagnoses for key substance use and public health outcomes are an urgent priority.

Acceptability and design preferences of supervised injection services among people who inject drugs in a mid-sized Canadian City

BACKGROUND

Supervised injection services (SIS) have been shown to reduce the public- and individual-level harms associated with injection drug use. While SIS feasibility research has been conducted in large urban centres, little is known about the acceptability of these services among people who inject drugs (PWID) in mid-sized cities. We assessed the prevalence and correlates of willingness to use SIS as well as design and operational preferences among PWID in London, Canada.

METHODS

Between March and April 2016, peer research associates administered a cross-sectional survey to PWID in London. Socio-demographic characteristics, drug-use patterns, and behaviours associated with willingness to use SIS were estimated using bivariable and multivariable logistic regression models. Chi-square tests were used to compare characteristics with expected frequency of SIS use among those willing to use SIS. Design and operational preferences are also described.

RESULTS

Of 197 PWID included in this analysis (median age, 39; interquartile range (IQR), 33-50; 38% female), 170 (86%) reported willingness to use SIS. In multivariable analyses, being female (adjusted odds ratio (AOR) 0.29; 95% confidence interval (CI) 0.11-0.75) was negatively associated with willingness to use, while public injecting in the last 6 months (AOR 2.76; 95% CI 1.00-7.62) was positively associated with willingness to use. Participants living in unstable housing, those injecting in public, and those injecting opioids and crystal methamphetamine daily reported higher expected frequency of SIS use (p < 0.05). A majority preferred private cubicles for injecting spaces and daytime operational hours, while just under half preferred PWID involved in service operations.

CONCLUSIONS

High levels of willingness to use SIS were found among PWID in this setting, suggesting that these services may play a role in addressing the harms associated with injection drug use. To maximize the uptake of SIS, programme planners and policy makers should consider the effects of gender and views of PWID regarding SIS design and operational preferences.

Initiation of drug dealing among a prospective cohort of street-involved youth

BACKGROUND

Street-involved youth who use drugs may have limited income-generation options and are known to commonly become immersed in illicit drug markets to generate funds. However, little attention has been given to factors that may drive drug dealing initiation among this vulnerable population.

OBJECTIVES

This longitudinal study examines drug dealing initiation among street-involved youth.

METHODS

Data were derived from the At-Risk Youth Study from September 2005 to November 2014; a prospective cohort of 194 street-involved youth who use drugs aged 14-26, in Vancouver, Canada. Extended Cox model was used to identify factors independently associated with time to first drug dealing.

RESULTS

Among street-involved youth who had never dealt drugs at baseline, 56 (29%) individuals initiated drug dealing during the study period for an incidence density of 13.0 per 100 person-years (95% confidence interval [CI]: 9.9-17.2). In multivariable Cox regression analysis, male gender (adjusted hazard ratio [AHR] = 1.90, 95% CI: 1.06-3.42), homelessness (AHR = 1.88, 95% CI: 1.05-3.35), crystal methamphetamine use (AHR = 2.48, 95% CI: 1.47-4.20), and crack cocaine use (AHR = 2.35, 95% CI: 1.38-4.00) were positively and independently associated with initiating drug dealing.

CONCLUSION

Homelessness and stimulant drug use were key risk factors for drug dealing initiation among street-involved youth. Findings indicate that evidence-based and innovative interventions, including youth-centric supportive housing, low threshold employment programs, and stimulant addiction treatment should be implemented and evaluated as strategies to help prevent this vulnerable population from engaging in risky illegal income generation practices.

A qualitative study of how Danish drug consumption rooms influence health and well-being among people who use drugs

Background

Drug use contributes to higher rates of morbidity and mortality among people who use drugs compared to the general population. In 2012, Danish politicians passed a law that allowed drug consumption rooms (DCRs) to operate; among the objectives were to improve the well-being of vulnerable citizens and to reduce the number of overdoses. Five Danish DCRs are currently being operated. This article presents results from a national investigation focused on assessing the impact of Danish drug consumption rooms on the health and well-being of DCR clients and factors facilitating the acceptance of DCR clients in order to improve their health and refer them onward to social and health service providers.

Methods

We conducted 250 h of participant observation in the DCRs, followed by in-depth qualitative interviews with 42 DCR clients and 25 staff members. Field notes and interviews were analysed and coded, and themes have been developed.

Results

DCR clients experienced a sense of social acceptance while inside DCRs. Members of staff conveyed a welcoming, non-judgemental attitude, and DCR clients were predominantly satisfied with the facilities. They prioritized forging relations with drug users so as to foster a sense of social acceptance within DCRs. The primary goal of staff members is to prevent overdoses by informing clients about strong drugs and by intervening in cases of intoxication. DCRs provide security to clients. In cases of health-related problems, DCR clients were referred to local health clinics. Members of the staff build bridges for DCR clients by guiding them towards drug treatment programmes and services in the social and the health sectors.

Conclusions

The study reveals a consistency between DCR clients and staff members with respect to appraisal of the importance of DCRs. Both clients and staff agreed that DCRs provide a safe haven in the environment in which DCR clients often live and that staff members’ approach to clients with the intention of promoting acceptance clears the path for the prevention and treatment of overdoses and providing referrals to healthcare facilities, to drug treatment centres and to social services.

Sex-Based Differences in Rates, Causes, and Predictors of Death Among Injection Drug Users in Vancouver, Canada

In the present study, we sought to identify rates, causes, and predictors of death among male and female injection drug users (IDUs) in Vancouver, British Columbia, Canada, during a period of expanded public health interventions. Data from prospective cohorts of IDUs in Vancouver were linked to the provincial database of vital statistics to ascertain rates and causes of death between 1996 and 2011. Mortality rates were analyzed using Poisson regression and indirect standardization. Predictors of mortality were identified using multivariable Cox regression models stratified by sex. Among the 2,317 participants, 794 (34.3%) of whom were women, there were 483 deaths during follow-up, with a rate of 32.1 (95% confidence interval (CI): 29.3, 35.0) deaths per 1,000 person-years. Standardized mortality ratios were 7.28 (95% CI: 6.50, 8.14) for men and 15.56 (95% CI: 13.31, 18.07) for women. During the study period, mortality rates related to infection with human immunodeficiency virus (HIV) declined among men but remained stable among women. In multivariable analyses, HIV seropositivity was independently associated with mortality in both sexes (all P < 0.05). The excess mortality burden among IDUs in our cohorts was primarily attributable to HIV infection; compared with men, women remained at higher risk of HIV-related mortality, indicating a need for sex-specific interventions to reduce mortality among female IDUs in this setting.
