The impact of social, structural and physical environmental factors on transitions into employment among people who inject drugs

Supervised Injecting Room Cohort Study (SIRX): study protocol

BACKGROUND

Supervised injecting facilities (SIFs) are designed to reduce the harms associated with injecting drug use and improve access to health and support services for people who need them. The Supervised Injecting Room Cohort Study (SIRX) aims to provide evidence of the effects, including cost-effectiveness, of a SIF embedded within a community health service, the Melbourne Medically Supervised Injecting Room (MSIR), which has a range of integrated harm reduction, health and social support services on-site.

METHODS AND ANALYSIS

The SIRX study design involves two prospective cohort studies that collect behavioural data and retrospectively and prospectively linked administrative data for primary and tertiary health services, criminal justice records, and mortality. The two cohorts are: (1) participants drawn from the existing Melbourne Injecting Drug User Cohort Study (SuperMIX; established in 2008-ongoing) through which participants consent to annual behavioural surveys (including serological testing for HIV and hepatitis B and C viruses) and linkage to administrative data; and (2) the SIRX-Registration Cohort (SIRX-R; established in 2024) comprising registered MSIR clients who consent to a baseline behavioural survey and administrative data linkage including the frequency of SIF use, and the uptake of on-site services. Primary outcomes are aligned to the legislated aims of the Melbourne MSIR, including ambulance-attended non-fatal overdoses and all-cause and drug-related mortality. Using causal inference methods, analyses will estimate the effect of MSIR exposure (frequent use/infrequent use/no use) on these primary outcomes. The SIRX study also has a secondary focus on the effect of MSIR exposure on health service use and related outcomes.

ETHICS AND DISSEMINATION

SuperMIX Study (599/21) and SIRX-R Study (71/23) ethics approvals were obtained from Alfred Hospital Research Ethics Committee. Participants will be assessed for capacity to provide informed consent following a detailed explanation of the study. Participants are informed of their right to withdraw from the study at any time and that withdrawing does not impact their access to services. Aggregated research results will be disseminated via presentations at national and international scientific conferences and publications in peer-reviewed journals. Local-level reports and outputs will be distributed to key study stakeholders and policymakers. Summary findings via accessible outputs (eg, short infographic summaries) for participants will be displayed in relevant services including the Melbourne MSIR and the study van, and distributed via Harm Reduction Victoria.

"Will you need this health at all? Will you be alive?": using the bioecological model of mass trauma to understand HIV care experiences during the war in Ukraine

INTRODUCTION

Russia's invasion of Ukraine in February 2022 has severely impacted the healthcare system, including the provision of HIV care. The ongoing war is a human-caused mass trauma, a severe ecological and psychosocial disruption that greatly exceeds the coping capacity of the community. The bioecological model of mass trauma builds on Bronfenbrenner's concept of interaction between nested systems to argue that social context determines the impact of life events on the individual and how an individual responds. This paper uses the bioecological model of mass trauma to explore the impact of Russia's aggression against Ukraine and the ongoing war on HIV-positive people who use drugs in Ukraine, a particularly vulnerable population that may be negatively affected by disruptions to social networks, healthcare infrastructure and economic conditions caused by mass trauma.

METHODS

Data were collected between September and November 2022. A convenience sample of 18 HIV-positive people who use drugs were recruited from community organizations that work with people living with HIV, drug treatment programmes, and HIV clinics through direct recruitment and participant referral. A total of nine men and nine women were recruited; the age ranged from 33 to 62 years old (mean = 46.44). Participants completed a single interview that explored how the war had affected their daily lives and access to HIV care and other medical services; their relationships with healthcare providers and social workers; and medication access, supply and adherence. Data were analysed using the Framework Method for thematic analysis.

RESULTS

The war had a profound impact on the social, emotional and financial support networks of participants. Changes in social networks, coupled with limited job opportunities and rising prices, intensified financial difficulties for participants. Relocating to different regions of Ukraine, staying at somebody else's home, and losing connections with social workers impacted medication adherence and created lengthy treatment gaps. Participants also experienced a decreased supply of antiretroviral therapy, concerns about accessing medication for opioid use disorder, and overwhelming fears associated with the war, which overshadowed their HIV-related health concerns and negatively impacted medication adherence.

CONCLUSIONS

Our analysis reveals the complex impact of war on social networks and healthcare access. Maintaining support networks and competent healthcare providers will be essential amid the ongoing war.

"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.

A qualitative exploration of daily path and daily routine among people in Ukraine who inject drugs to understand associated harms

Background

Patterns of movement, heterogeneity of context, and individual space-time patterns affect health, and individuals’ movement throughout the landscape is shaped by addiction, meeting basic needs, and maintaining relationships. Place and social context enable or constrain behavior and individuals use social networks and daily routines to accomplish individual goals and access resources.

Methods

This article explores drug use as part of daily routines and daily paths among people who inject drugs in Dnipro City, Ukraine. Between March and August 2018, we interviewed 30 people who inject drugs living in Dnipro City, Ukraine. Study participants completed a single interview that lasted between 1 and 2 hours. During the interview, participants described their daily routine and daily path using a printed map of Dnipro as a prompt. Participants were asked to draw important sites; give time estimates of arrival and departure; and annotate on the map the points, paths, and areas most prominent or important to them. Participants also described to what extent their daily routines were planned or spontaneous, how much their daily path varied over time, and how drug use shaped their daily routine.

Results

We identified 3 major types of daily routine: unpredictable, predictable, and somewhat predictable. Participants with unpredictable daily routines had unreliable sources of income, inconsistent drug suppliers and drug use site, and dynamic groups of people with whom they socialized and used drugs. Participants with predictable daily routines had reliable sources of income, a regular drug dealer or stash source, and a stable group of friends or acquaintances with whom they bought and/or used drugs. Participants with somewhat predictable daily routines had some stable aspects of their daily lives, such as a steady source of income or a small group of friends with whom they used drugs, but also experienced circumstances that undermined their ability to have a routinized daily life, such as changing drug use sites or inconsistent income sources.

Conclusions

Greater attention needs to be paid to the daily routines of people who use drugs to develop and tailor interventions that address the place-based and social contexts that contribute to drug-use related risks.

Cohort Profile: The Assessing Economic Transitions (ASSET) Study-A Community-Based Mixed-Methods Study of Economic Engagement among Inner-City Residents

The Assessing Economic Transitions (ASSET) study was established to identify relationships between economic engagement, health and well-being in inner-city populations given that research in this area is currently underdeveloped. This paper describes the objectives, design, and characteristics of the ASSET study cohort, an open prospective cohort which aims to provide data on opportunities for addressing economic engagement in an inner-city drug-using population in Vancouver, Canada. Participants complete interviewer-administered surveys quarterly. A subset of participants complete nested semi-structured qualitative interviews semi-annually. Between April 2019 and May 2022, the study enrolled 257 participants ages 19 years or older (median age: 51; 40% Indigenous, 11.6% non-Indigenous people of colour; 39% cis-gender women, 3.9% transgender, genderqueer, or two-spirit) and 41 qualitative participants. At baseline, all participants reported past daily drug use, with 27% currently using opioids daily, and 20% currently using stimulants daily. In the three months prior to baseline, more participants undertook informal income generation (75%) than formal employment (50%). Employed participants largely had casual jobs (42%) or jobs with part-time/varied hours (35%). Nested qualitative studies will focus on how inner-city populations experience economic engagement. The resulting evidence will inform policy and programmatic initiatives to address socioeconomic drivers of health and well-being.

'Progression capitals': How homeless health peer advocacy impacts peer advocates

This article presents analysis from a qualitative evaluation of a homeless health peer advocacy (HHPA) service in London, United Kingdom. Whilst evidence is growing for the impact of peer programming on clients, understanding of the impact on peers themselves is limited in the context of homelessness. Research here is vital for supporting sustainable and effective programmes.

Analysis of interview data with 14 current and former peer advocates, 2 members of staff and 3 external stakeholders suggests peer advocacy and its organizational setting can generate social, human, cultural and physical resources to help peer advocates fulfil their own life goals. We explore these with reference to ‘recovery capital’, reframed as ‘progression capitals’ to reflect its relevance for pursuits unrelated to clinical understandings of recovery. Progression capitals can be defined as resources to pursue individually determined goals relating to self-fulfilment.

We find engagement with, and benefits from, a peer advocacy service is most feasible among individuals already possessing some ‘progression capital’. We discuss the value of progression capitals for peers alongside the implications of the role being unsalaried within a neoliberal political economy, and comment on the value that the progression capitals framework offers for the development and assessment of peer interventions more broadly.

•

HHPA can support advocates to ‘recover’ from health issues and fulfil self-defined life goals.

•

Reframing ‘recovery capital’ as ‘progression capitals’ better captures HHPA's impact on peers.

•

Progression capitals are resources to pursue self-determined goals relating to fulfilment.

•

Organizations should maximize the progression capitals such programmes can enable for peers.

•

Progression capitals offer a framework for developing/assessing peer programmes across sectors.

Income generation and the patterning of substance use: A gender-based analysis

BACKGROUND

Previous research has demonstrated how income-generating activities among marginalized people who use drugs (PWUD)-including employment, income assistance, street-based activities, sex work, and illegal activities-can provide both benefit (e.g., additional income) and harm (e.g., violence, criminalization). However, little is known about gender differences in factors such as drug use patterns that are associated with income-generating activities among PWUD.

METHODS

Using data from prospective cohorts of HIV-positive and HIV-negative PWUD in Vancouver, Canada, we conducted exploratory gender-stratified analyses of associations between substance use patterns and income-generating activities, using generalized linear mixed-models.

RESULTS

Participants reported income sources as employment (23.4 %), income assistance (88.1 %), street-based activities (24.9 %), sex work (15.2 %), drug dealing (31.5 %), or other illegal activities (13.9 %). GLMM results showed gendered patterns of engagement in specific income-generating activities and some diverging patterns of substance use. For instance, men receiving income assistance were less likely to use opioids (Adjusted odds ratio(AOR) = 0.64; 95 % confidence interval(CI) = 0.50-0.82) and women engaged in sex work were more likely to use crack-cocaine (AOR = 2.74, 95 % CI = 2.22-3.37). However, results reflected primarily converging patterns of substance use between women and men across income-generating activities, particularly for drug dealing and other illegal activities.

CONCLUSIONS

Our results suggest that substance use patterns may be more closely associated with income generation context than gender. Given potential harms associated with some income generation activities, results highlight the need for further investigation of the social and structural context of income generation, its intersections with gender and substance use, and the expansion of low-threshold work opportunities.

Experimental (Re)structuring: The Clinical Trial as Turning Point Among Medical Research Participants

Amid the growth of addiction medicine randomized controlled trials (RCTs), scholars have begun examining participants' study experiences, highlighting facilitators and barriers to enrollment. However, this work can overlook the interplay between trial participation and social-structural dimensions among people with substance use disorders linked to the social nature of use, socioeconomic marginalization, and time demands of substance procurement and use. To effectively conduct RCTs with this unique population, it is necessary to examine the broader social context of study participation. We conducted nested qualitative interviews with 22 participants involved in an RCT testing a treatment for alcohol and opioid use disorders in HIV clinics. Thematic analyses revealed social-structural circumstances shaping RCT participation as well as how participation constitutes a turning point, prompting individuals to reconfigure social networks, reorient to spatial environments, and reorganize day-to-day life-with implications for how substance use disorder RCTs should be approached by researchers.

How urban and rural built environments influence the health attitudes and behaviors of people who use drugs

Research suggests that the built environment is associated with drug use. However, there is limited scholarship focusing on specific features of the built environment that influence drug use behaviors, experiences, and patterns and how risk factors for drug use are placed in distinctive urban and rural settings. Applying Neely and Samura's conceptual theory that describes space as contested, fluid and historical, interactional and relational, and defined by inequality and difference, we assessed data from semi-structured qualitative interviews conducted between 2019 and 2020 with consumers at syringe exchange programs (SEPs) in an urban location (New York City) and a rural location (southern Illinois). We aimed to contextualize how drug use manifests in each space. In total, 65 individuals, including 59 people who use drugs (PWUD) and six professionals who worked with PWUD, were interviewed. Findings illustrate that, in both the urban and rural setting, the built environment regulates the drug use milieu by mediating social reproduction, namely the degree of agency PWUD exert to acquire and use drugs where they desire. Processes of "stigma zoning," defined as socio-spatial policing of boundaries of behavior deemed undesirable or deviant, impacted PWUD's socio-geographic mobility, social conditions, and resource access, and modulated PWUD's broader capacity and self-efficacy. Similar patterns of drug use, according to social and economic inequities chiefly related to housing instability, were further observed in both settings.

Understanding the impact of the SARS-COV-2 pandemic on hospitalized patients with substance use disorder

Background

The SARS-COV-2 pandemic rapidly shifted dynamics around hospitalization for many communities. This study aimed to evaluate how the pandemic altered the experience of healthcare, acute illness, and care transitions among hospitalized patients with substance use disorder (SUD).

Methods

We performed a qualitative study at an academic medical center in Portland, Oregon, in Spring 2020. We conducted semi-structured interviews, and conducted a thematic analysis, using an inductive approach, at a semantic level.

Results

We enrolled 27 participants, and identified four main themes: 1) shuttered community resources threatened patients’ basic survival adaptations; 2) changes in outpatient care increased reliance on hospitals as safety nets; 3) hospital policy changes made staying in the hospital harder than usual; and, 4) care transitions out of the hospital were highly uncertain.

Discussion

Hospitalized adults with SUD were further marginalized during the SARS-COV-2 pandemic. Systems must address the needs of marginalized patients in future disruptive events.

"Running myself ragged": stressors faced by peer workers in overdose response settings

BACKGROUND

Peer workers or "peers" (workers with past or present drug use experience) are at the forefront of overdose response initiatives, and their role is essential in creating safe spaces for people who use drugs (PWUD). Working in overdose response settings has benefits for peer workers but is also stressful, with lasting emotional and mental health effects. Yet, little is known about the stressors peer workers face and what interventions can be implemented to support them in their roles.

METHODS

This project used a community-based sequential mixed-methods research design. Eight peer researcher-led focus groups (n = 31) were conducted between November 2018 and March 2019 to assess needs of peer workers. The transcripts were thematically coded and analysed using interpretative description. These results informed a survey, which was conducted (n = 50) in September 2019 to acquire quantitative data on peer workers' perception of health, quality of life, working conditions and stressors. Frequency distributions were used to describe characteristics of participants. X2 distribution values with Yates correction were conducted to check for association between variables.

RESULTS

Five themes emerged from the focus groups that point to stressors felt by peer workers: (1) financial insecurity; (2) lack of respect and recognition at work; (3) housing challenges; (4) inability to access and/or refer individuals to resources; and (5) constant exposure to death and trauma. Consistent with this, the factors that survey participants picked as one of their "top three stressors" included financial situation, work situation, and housing challenges.

CONCLUSION

Peer workers are faced with a diversity of stressors in their lives which often reflect societal stigmatization of drug use. Recognition of these systemic stressors is critical in designing interventions to ease the emotional, physical and financial burden faced by peer workers.

"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.

Essential work, precarious labour: The need for safer and equitable harm reduction work in the era of COVID-19

This commentary highlights labour concerns and inequities within the harm reduction sector that hinder programs' ability to respond to converging public health emergencies (the overdose crisis and COVID-19), and potentially contribute to spread of the novel coronavirus. Many harm reduction programs continue to support people who use illicit drugs (PWUD) during the pandemic, yet PWUD working in harm reduction programs (sometimes termed 'peers') experience precarious labour conditions characterized by low wages, minimal employee benefits (such as paid sick leave) and high employment insecurity. Along with precarious labour conditions, PWUD face heightened vulnerabilities to COVID-19 and yet have been largely overlooked in global response to the pandemic. Operating under conditions of economic and legal precarity, harm reduction programs' reliance on precarious labour (e.g. on-call, temporary and unpaid work) renders some services vulnerable to staffing shortages and service disruptions during the pandemic, while also heightening the risk of virus transmission among workers, service users and their communities. We call for immediate policy and programmatic actions to strengthen working conditions within these settings with a priority on enhancing protections and supports for workers in peer roles.

Compassionate Care of the Patient Who Uses Substances: Implications for the Infusion Nurse

Given the high rate of infection secondary to substance use, infusion nurses have a unique opportunity to compassionately engage individuals with substance use problems. Compassion is an essential ingredient of nursing practice, yet compassionate care of the individual who uses substances may seem difficult to navigate. This article provides the infusion nurse with the essential principles of compassionate care of the patient who uses substances. A fundamental understanding of how to work with patients who use substances may enhance the infusion nurse's practice.

Employment Cessation, Long Term Labour Market Engagement and HIV Infection Risk Among People Who Inject Drugs in an Urban Canadian Setting

The potential for changes in socio-economic status, such as employment exits, to increase HIV infection risk are not well examined among people who inject illicit drugs (PWID). We used longstanding cohort data from Vancouver, Canada, to longitudinally assess associations between employment cessation and outcomes with documented linkages to HIV infection risk among PWID. From 2005 to 2015, 1222 participants reported 1154 employment exits. Employment exits were significantly associated with transitions into unstable housing; moving to the inner-city; initiating informal, prohibited or illegal income generation; high risk drug use practices; and exiting methadone maintenance therapy. HIV infection rates were higher among participants with lower long-term labour market engagement. These findings suggest that employment cessation coincides with initiating exposure to aspects of socioeconomic marginalization and drug use associated with HIV infection risk. Support for employment retention that prevents poverty entrenchment and harmful drug use could contribute to HIV prevention measures for PWID.

Sexual risk behaviors and STDs among persons who inject drugs: A national study

Opioid use and the rising case reports of STDs represent co-occurring epidemics; research indicates that persons who inject drugs (PWID) may be at increased risk for acquiring STDs. We use the National Survey of Family Growth (NSFG, 2011-2015) to examine the prevalence of risky sexual behaviors and STD diagnoses among PWID. We describe demographic characteristics, sexual behaviors, and self-reported STD diagnoses of sexually active women and men, separately, by whether they had ever engaged in injection-related behaviors (age 15-44; N = 9006 women, N = 7210 men). Results indicate that in 2011-15, 1.4% of women and 2.6% of men reported ever engaging in injection-related behaviors. Examining the full logistic regression models indicate that for women, sex with a PWID in the past 12 months (AOR = 5.8, 95% CI: 2.9, 11.7), exchanging money/drugs for sex in the past 12 months (AOR = 3.6, 95% CI: 1.2, 10.9), chlamydia and/or gonorrhea diagnosis in the past 12 months (AOR = 2.6, 95% CI: 1.2, 5.3), ever having a syphilis diagnosis (AOR = 8.5, 95% CI: 3.1, 23.4), and ever having a herpes diagnosis (AOR = 3.3, 95% CI: 1.0, 10.3) were associated with increased odds of engaging in injection-related behaviors. For men, sex with a PWID in the past 12 months (AOR = 10.9, 95% CI: 4.3, 27.7), ever being diagnosed with syphilis (AOR = 5.8, 95% CI: 1.8, 18.0), and ever being diagnosed with herpes (AOR = 2.7, 95% CI: 1.0, 7.1) were significantly associated with increased odds of engaging in injection-related behaviors. Future research may examine critical intervention points, including co-occurring factors in both STD acquisition and injection drug use.

Transitions in income generation among marginalized people who use drugs: A qualitative study on recycling and vulnerability to violence

BACKGROUND

Income is an important determinant of health among people who use drugs (PWUD). However, understanding transitions between differing types of income generation within the formal and informal economy and how they can be shaped by vulnerability to risk and harm remain poorly understood. This study examines how transitions in income-generating activities are shaped by and influence exposure to violence among marginalised PWUD, in Vancouver, Canada's, Downtown Eastside (DTES) neighbourhood.

METHODS

Qualitative interviews were conducted with twenty-six individuals engaged in informal and illegal income-generating activities in the DTES. Interview transcripts were analyzed thematically, focusing on relationships between income generation and violence during the study period between January 2014 to April 2015 and drew upon concepts of social violence when interpreting these themes.

RESULTS

Participants' engagement in informal and illegal income-generating activities represented a means to negotiate survival given multiple barriers to formal employment and inadequate economic supports. Our findings highlight how informal and illegal income-generating activities in the DTES are characterized by structural, symbolic and everyday violence, while transitions from 'high risk' (e.g., sex work, drug dealing) to perceived 'low risk' (e.g., recycling) activities represent attempts to reduce exposure to violence. However, participants emphasized how informal income generation was nonetheless shaped by structural violence (e.g., gendered hierarchies and police harassment), experienced as everyday violence, and introduced exposure to alternate risks.

CONCLUSION

Our findings underscore the critical role of income generation in shaping exposure to violence, highlighting the need for low-threshold employment interventions targeting PWUD as a central component of harm reduction strategies.

Informal recycling, income generation and risk: Health and social harms among people who use drugs

BACKGROUND

Informal recycling refers to the street-based collection of discarded materials for reuse, resale, or return to a recycling facility for money. While qualitative research has explored experiences and perceptions of informal recycling, little is known about the scope and exposures associated with informal recycling among people who use drugs (PWUD).

METHODS

Using data from two prospective longitudinal cohorts of PWUD, we examined the prevalence of informal recycling and its association with social, structural and health risks, including criminal justice system involvement.

RESULTS

Between June 2010 and May 2015, of 1664 participants, 557 (33.5%) reported engaging in informal recycling during the study period. In multivariable generalised estimating equations (GEE) analyses, informal recycling was positively associated with injection drug use (Adjusted Odds Ratio (AOR) = 1.43, 95% Confidence Interval (CI) 1.21-1.68), public injection (AOR = 1.27, 95% CI 1.09-1.49), methamphetamine use (AOR = 1.35, 95% CI 1.05-1.72), difficulty finding harm reduction equipment (AOR = 1.16, 95% CI 1.02-1.32), and police interactions (AOR = 1.35, 95% CI 1.18-1.55). Sub-analyses revealed PWUD engaged in informal recycling were more likely to be told to move on, ticketed, stopped for jaywalking, and directed to services by police.

CONCLUSIONS

These findings suggest informal recycling as a situated practice for PWUD, with potential indications for higher-risk drug use, experiencing greater surveillance, and difficulty accessing health and addiction treatment services. This research highlights the significance of the broader risk environment and the need for health-promoting policies for socioeconomically marginalised PWUD engaged in informal recycling.

State and Local Determinants of Employment Outcomes Among Individuals With Disabilities

In the United States, employment rates among individuals with disabilities are persistently low but vary substantially. In this study, we examined the relationship between employment outcomes and features of the state and county physical, economic, and policy environment among a national sample of individuals with disabilities. To do so, we merged a set of state- and county-level environmental variables with data from the 2009–2011 American Community Survey accessed in a U.S. Census Research Data Center. We estimated regression models of employment, work hours, and earnings as a function of disability, personal characteristics, and these environmental features. We found that economic conditions and physical environmental variables had stronger associations than policy variables with employment outcomes. Although the estimated importance of environmental variables was small relative to individual disability and personal characteristics, our results suggest that these variables may present barriers or facilitators to employment that can explain some geographic variation in employment outcomes across the United States.

The perspectives of structurally vulnerable people who use drugs on volunteer stipends and work experiences provided through a drug user organization: Opportunities and limitations

BACKGROUND

While drug user organizations (DUO) have received public health attention as a means to potentially reduce the harms associated with drug use, there is a lack of research on the compensation and structural forces that promote or inhibit participation in DUO. Against the backdrop of structural vulnerability experienced by people who use drugs (PWUD), we examined the impact of monetary 'volunteer stipends' provided through a DUO and explore their role in providing low-threshold employment opportunities and shaping participation in DUO.

METHODS

Participants were purposively sampled to reflect a range of perspectives and experiences volunteering at Vancouver Area Network of Drug Users (VANDU) and receiving stipends. Semi-structured qualitative interviews were conducted with 23 members of VANDU. Interview transcripts were coded in Atlas.ti 7 for key a priori themes and emergent categories from the data and analyzed thematically.

RESULTS

Stipends provided participants with symbolic and material recognition of the time, effort, and expertise they contribute to the organization, and functioned to facilitate ongoing participation. Payments that rewarded, skills, labour and drug-related knowledge reduced participant's perception of stigma against PWUD. Paid work in VANDU further provided participants with non-material benefits commonly attributed to regular employment, including social connections and a sense of purpose. Participants also identified the low level of pay as a limitation of VANDU's paid participation program. The daily demands of survival (accessing shelter, food, and drugs) posed more complex structural vulnerabilities to participate in VANDU, as small stipends were not sufficient to address these needs.

CONCLUSION

Low threshold employment opportunities within DUO may provide significant individual and public health benefits. However, these benefits are constrained by the small size of stipends. Therefore, to ensure better inclusion of PWUD, our findings recommend the development and expansion of equitable, accessible, well-paying employment programs for PWUD.

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.

Employment after beginning treatment for substance use disorders: The impact of race/ethnicity and client community of residence

Employment is an important substance use treatment outcome, frequently used to assess individual progress during and after treatment. This study examined whether racial/ethnic disparities exist in employment after beginning treatment. It also examined the extent to which characteristics of clients' communities account for such disparities. Analyses are based on data that linked individual treatment information from Washington State's Behavioral Health Administration with employment data from the state's Employment Security Department. Analyses subsequently incorporated community-level data from the U.S. Census Bureau. The sample includes 10,636 adult clients (Whites, 68%; American Indians, 13%, Latinos, 10%; and Blacks, 8%) who had a new outpatient treatment admission to state-funded specialty treatment. Heckman models were used to test whether racial/ethnic disparities existed in the likelihood of post-admission employment, as well as employment duration and wages earned. Results indicated that there were no racial/ethnic disparities in the likelihood of employment in the year following treatment admission. However, compared to White clients, American Indian and Black clients had significantly shorter lengths of employment and Black clients had significantly lower wages. With few exceptions, residential community characteristics were associated with being employed after initiating treatment, but not with maintaining employment or with wages. After accounting for community-level variables, disparities in length of employment and earned wages persisted. These findings highlight the importance of considering the race/ethnicity of a client when examining post-treatment employment alongside community characteristics, and suggest that the effect of race/ethnicity and community characteristics on post-treatment employment may differ based on the stage of the employment process.

Integrated HIV care and service engagement among people living with HIV who use drugs in a setting with a community-wide treatment as prevention initiative: a qualitative study in Vancouver, Canada

INTRODUCTION

Social-structural inequities impede access to, and retention in, HIV care among structurally vulnerable people living with HIV (PLHIV) who use drugs. The resulting disparities in HIV-related outcomes among PLHIV who use drugs pose barriers to the optimization of HIV treatment as prevention (TasP) initiatives. We undertook this study to examine engagement with, and impacts of, an integrated HIV care services model tailored to the needs of PLHIV who use drugs in Vancouver, Canada - a setting with a community-wide TasP initiative.

METHODS

We conducted qualitative interviews with 30 PLHIV who use drugs recruited from the Dr. Peter Centre, an HIV care facility operating under an integrated services model and harm reduction approach. We employed novel analytical techniques to analyse participants' service trajectories within this facility to understand how this HIV service environment influences access to, and retention in, HIV care among structurally vulnerable PLHIV who use drugs.

RESULTS

Our findings demonstrate that participants' structural vulnerability shaped their engagement with the HIV care facility that provided access to resources that facilitated retention in HIV care and antiretroviral treatment adherence. Additionally, the integrated service environment helped reduce burdens associated with living in extreme poverty by meeting participants' subsistence (e.g. food, shelter) needs. Moreover, access to multiple supports created a structured environment in which participants could develop routine service use patterns and have prolonged engagement with supportive care services. Our findings demonstrate that low-barrier service models can mitigate social and structural barriers to HIV care and complement TasP initiatives for PLHIV who use drugs.

CONCLUSION

These findings highlight the critical role of integrated service models in promoting access to health and support services for structurally vulnerable PLHIV. Complementing structural interventions with integrated service models that are tailored to the needs of structurally vulnerable PLHIV who use drugs will be pursuant to the goals of TasP.

Income generation and attitudes towards addiction treatment among people who use illicit drugs in a Canadian setting

INTRODUCTION

Socioeconomically marginalized people who use illicit drugs (PWUD) often engage in alternative income generating activities to meet their basic needs. These activities commonly carry a number of health and social risks, which may prompt some PWUD to consider addiction treatment to reduce their drug use or drug-related expenses. We sought to determine whether engaging in certain forms of income generation was independently associated with self-reported need for addiction treatment among a cohort of PWUD in Vancouver, Canada.

METHODS

Data from two prospective cohorts of PWUD in Vancouver were used in generalized estimating equations to identify factors associated with self-reported need for addiction treatment, with a focus on income generating activities.

RESULTS

Between June 2013 and May 2014, 1285 respondents participated in the study of whom 483 (34.1%) were female and 396 (30.8%) indicated that they needed addiction treatment. In final multivariate analyses, key factors significantly and positively associated with self-reported need for addiction treatment included engaging in illegal income generating activities (adjusted odds ratio [AOR]=1.96, 95% confidence interval [CI}: 1.11-3.46); sex work (AOR=1.61, 95% CI: 1.05-2.47), homelessness (AOR=1.65, 95% CI: 1.22-2.25); and recent engagement in counselling (AOR=1.85, 95% CI: 1.40-2.44).

DISCUSSION

Our results suggest that key markers of socioeconomic marginalization are strongly linked with a stated need for addiction treatment. These findings underscore the need to provide appropriate and accessible addiction treatment access to marginalized PWUD and to consider alternative approaches to reduce socioeconomic disadvantage.

Increased drug use and the timing of social assistance receipt among people who use illicit drugs

BACKGROUND

The monthly disbursement of social assistance (SA) payments to people who use illicit drugs (PWUD) has been temporally associated with increases in drug-related harm. Yet, whether SA receipt changes drug use intensity compared to levels of use at other times in the month has not been established. We therefore examined this relationship among PWUD in Vancouver, Canada (2005-2013).

METHODS

Data were derived from prospective cohorts of HIV-positive and HIV-negative PWUD. Every six months, participants were asked about their illicit drug use during the last 180 days and the past week. We determined whether SA receipt occurred within the assessment's one-week recall period. We employed generalized estimating equations controlling for confounders to examine the relationship between SA receipt and the change in drug use intensity, defined as a 100% increase in the average times per day a given drug was used in the last week compared to the previous 6 months. We tested the robustness of this relationship by stratifying analyses by whether individuals primarily used stimulants, illicit opioids or engaged in polydrug use and examining the timing of SA receipt relative to date of assessment.

RESULTS

Our study included 2661 individuals (median age 36, 32% female) with 1415 (53.2%) reporting SA receipt occurring within the one-week recall period of the assessment at least once. SA receipt was independently associated with intensified drug use (Adjusted Odds Ratio [AOR]: 1.79; 95% Confidence Interval [CI]: 1.53, 2.09), and remained significant when stratified by primary use of stimulants (AOR: 1.87; 95% CI: 1.54, 2.26), opioids (AOR: 1.96; 95% CI: 1.23, 3.13) and polydrug use (AOR: 1.53; 95% CI: 1.11, 2.10).

CONCLUSION

We found a temporal association between SA receipt and drug use intensification. While the health and social benefits of SA are significant, these findings suggest that alternative disbursement strategies, such as staggered or smaller and more frequent SA payments may be able to mitigate drug-related harm. Alternatives should be tested rigorously.

Inability to access health and social services associated with mental health among people who inject drugs in a Canadian setting

BACKGROUND

People who inject drugs (PWID) face barriers to healthcare due to reasons including comorbidity. We evaluated access to health and social services by three of the most prevalent comorbid conditions among PWID: HIV, hepatitis C (HCV), and mental health, in an urban setting in Canada.

METHODS

Data were derived from prospective cohorts of community-recruited PWID between 2005 and 2015. HIV and HCV serostatuses were based on antibody tests, while mental health conditions and inability to access health and social services (barriers to access) were determined by participants' self-report. We employed generalized linear mixed models controlling for confounders to examine associations between health conditions and barriers to access.

RESULTS

Among 2494 participants, 1632 (65.4%) reported barriers to access at least once over a median of seven (IQR: 3, 12) semi-annual assessments. Mental health conditions were independently associated with increased odds of reporting barriers (adjusted Odds Ratio (aOR): 1.45, 95% Confidence Interval (CI): 1.32, 1.58), while HIV was not (aOR: 0.96, 95% CI: 0.85, 1.08), and HCV was associated with decreased odds (aOR: 0.80, 95% CI: 0.69, 0.93). The associations between mental health conditions and barriers to access were consistent among PWID without HIV/HCV (aOR: 1.35, 95% CI: 1.10, 1.65), with HCV mono-infection (aOR: 1.55, 95% CI: 1.37, 1.75), and HCV/HIV co-infection (aOR: 1.36, 95% CI: 1.15, 1.60).

CONCLUSIONS

Targeted strategies to seek and treat mental health conditions in settings that serve PWID, and assist PWID with mental health conditions in navigating healthcare system may improve the publicly-funded health and social services.

Meaningful engagement of people living with HIV who use drugs: methodology for the design of a Peer Research Associate (PRA) hiring model

Background

Community-based HIV, harm reduction, and addiction research increasingly involve members of affected communities as Peer Research Associates (PRAs)—individuals with common experiences to the participant population (e.g. people who use drugs, people living with HIV [PLHIV]). However, there is a paucity of literature detailing the operationalization of PRA hiring and thus limited understanding regarding how affected communities can be meaningfully involved through low-barrier engagement in paid positions within community-based participatory research (CBPR) projects. We aim to address this gap by describing a low-threshold PRA hiring process.

Results

In 2012, the BC Centre for Excellence in HIV/AIDS and the Dr. Peter AIDS Foundation collaborated to develop a mixed-method CBPR project evaluating the effectiveness of the Dr. Peter Centre (DPC)—an integrative HIV care facility in Vancouver, Canada. A primary objective of the study was to assess the impact of DPC services among clients who have a history of illicit drug use. In keeping with CBPR principles, affected populations, community-based organizations, and key stakeholders guided the development and dissemination of a low-barrier PRA hiring process to meaningfully engage affected communities (e.g. PLHIV who have a history of illicit drug use) in all aspects of the research project.

The hiring model was implemented in a number of stages, including (1) the establishment of a hiring team; (2) the development and dissemination of the job posting; (3) interviewing applicants; and (4) the selection of participants. The hiring model presented in this paper demonstrates the benefits of hiring vulnerable PLHIV who use drugs as PRAs in community-based research.

Conclusions

The provision of low-barrier access to meaningful research employment described herein attempts to engage affected communities beyond tokenistic involvement in research. Our hiring model was successful at engaging five PRAs over a 2-year period and fostered opportunities for future paid employment or volunteer opportunities through ongoing collaboration between PRAs and a diverse range of stakeholders working in HIV/AIDS and addictions. Additionally, this model has the potential to be used across a range of studies and community-based settings interested in meaningfully engaging communities in all stages of the research process.

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.

Reducing Economic Disparities for Female Offenders: The Oxford House Model

BACKGROUND

In the past 30 years the rate of increase in incarceration for females who abuse substances has outpaced that of men. Women have increased health and economic disparities, and face barriers to economic mobility, increasing their risk of returning to the criminal justice system. Past research suggests that there is a positive relationship between living in Oxford House and employment wages, yet the impact of having a criminal history on this relationship was unknown.

METHOD

This study used a nationwide sample of 136 women living in Oxford Houses in a regression analysis with length of stay in Oxford House predicting employment wages, and moderated by criminal history.

RESULTS

There was a positive relationship between length of stay and wages. Criminal history modified the association between length of stay and wages, and length of stay had a significantly greater impact on wages for women with criminal convictions.

IMPLICATIONS

The findings provide a contribution to alcohol and drug abuse and economic literature by identifying a setting that decreases economic disparities for formerly incarcerated women. Results can inform future policy, research, and the development of gender sensitive aftercare programs that address the needs of women, assisting transitioning women in reentering mainstream society, and increasing their chances of obtaining and retaining employment.

Building recovery capital through peer harm reduction work

Purpose

– Peer harm reduction programmes engage service users in service delivery and may help peers to develop employment skills, better health, greater stability, and new goals. Thus far, peer work has not been discussed as an intervention to promote recovery. The purpose of this paper is to provide findings related to two research questions: first,do low-threshold employment programmes have the potential to contribute to positive recovery capital, and if so, how? Second, how are such programmes designed and what challenges do they face in supporting the recovery process?

Design/methodology/approach

– Using a community-based research approach, data were collected at a Toronto, Canada community health centre using in-depth interviews with peer workers (n=5), staff (n=5), and programme clients (n=4) and two focus groups with peer workers (n=12). A thematic analysis was undertaken to describe the programme model and to explore the mechanisms by which participation contributes to the development of recovery capital.

Findings

– The design of the Regent Park Community Health Centre peer work model demonstrates how opportunities for participation in community activities may spark cumulative growth in positive recovery capital within the community of PUDs. However, the recovery contagion of peer work may lose momentum with insufficient opportunities for new and experienced peer workers.

Originality/value

– Using the concept of recovery capital, the authors demonstrate how low-threshold employment interventions have the potential to contribute to the development of positive recovery capital.

Sex work and HIV incidence among people who inject drugs

OBJECTIVE

Although the global burden of HIV infection among sex workers (SW) has been well recognized, HIV-related risks among sex workers who inject drugs (SW-IDU) have received less attention. We investigated the relationship between sex work and HIV incidence among people who inject drugs (IDU) in a Canadian setting.

DESIGN

Prospective cohort study.

METHODS

Using Kaplan-Meier methods and the extended Cox regression, we compared HIV incidence among SW-IDU and non-SW-IDU in Vancouver, Canada, after adjusting for potential confounders.

RESULTS

Between 1996 and 2012, 1647 participants were included in the study, including 512 (31.1%) IDU engaged in sex work. At 5 years the HIV cumulative incidence was higher among SW-IDU in comparison to other IDU (12 vs. 7%, P = 0.001). In unadjusted Cox regression analyses, HIV incidence among SW-IDU was also elevated [relative hazard: 1.69; 95% confidence interval (CI): 1.13-2.53]. However, in a multivariable analysis, sex work did not remain associated with HIV infection (adjusted relative hazard: 0.74; 95% CI: 0.45-1.20), with cocaine injection appearing to account for the elevated risk for HIV infection among SW-IDU.

CONCLUSION

These data suggest that local SW-IDU have elevated rates of HIV infection. However, our exploration of risk factors among SW-IDU demonstrated that drug use patterns and environmental factors, rather than sexual risks, may explain the elevated HIV incidence among SW-IDU locally. Our findings highlight the need for social and structural interventions, including increased access to harm reduction programs and addiction treatment.

Protective factors associated with short-term cessation of injection drug use among a Canadian cohort of people who inject drugs

INTRODUCTION AND AIMS

Strategies are needed to transition persons who inject drugs out of injecting. We undertook this study to identify protective factors associated with cessation of injection drug use.

DESIGN AND METHODS

Data were derived from three prospective cohorts of people who use illicit drugs in Vancouver, Canada, between September 2005 and November 2011. Generalised estimating equations were used to examine protective factors and 6-month cessation of injection drug use.

RESULTS

Our sample of 1663 people who inject drugs included 563 (33.9%) women, and median age was 40 years. Overall, 904 (54.4%) individuals had at least one 6-month injection cessation event. In multivariable analysis, protective factors associated with cessation of injection drug use included the following: having a regular place to stay [adjusted odds ratio (AOR) = 1.30; 95% confidence interval (CI) 1.13-1.48]; formal employment (AOR = 1.12; 95% CI 1.01-1.23); social support from personal contacts (AOR = 1.22; 95% CI 1.10-1.35); social support from professionals (AOR = 1.26; 95% CI 1.14-1.39); ability to access health and social services (AOR = 1.21; 95% CI 1.09-1.34); and positive self-rated health (AOR = 1.21, 95% CI 1.11-1.32).

DISCUSSION AND CONCLUSIONS

Over half of people who inject drugs in this study reported achieving 6-month cessation of injection drug use, with cessation being associated with a range of modifiable protective factors. Policy makers and practitioners should promote increased access to stable housing, employment, social support and other services to promote cessation of injection drug use.

Socioeconomic marginalization and plasma HIV-1 RNA nondetectability among individuals who use illicit drugs in a Canadian setting

OBJECTIVE

Given that people who use illicit drugs (PWUD) often engage in prohibited income generation to support their basic needs, we sought to examine the role of these activities in shaping antiretroviral therapy (ART) adherence and plasma HIV RNA-1 viral load suppression among HIV-infected PWUD.

DESIGN

Longitudinal analyses among HIV-positive, ART-exposed PWUD in the AIDS Care Cohort to evaluate Exposure to Survival Services prospective cohort study (2005-2013).

METHODS

Generalized linear mixed-effects and mediation analyses examined the relationship between prohibited income generation (e.g., sex work, drug dealing, theft, street-based income) and virologic suppression (plasma viral load ≤50 copies/ml plasma) adjusting for adherence and potential confounders.

RESULTS

Among 687 HIV-infected PWUD, 391 (56.9%) individuals reported prohibited income generation activity during the study period. In multivariate analyses, prohibited income generation remained independently and negatively associated with virologic suppression (adjusted odds ratio: 0.68, 95% confidence interval: 0.52-0.88) following adjustment for hypothesized confounders, including high-intensity drug use, ART adherence and homelessness. Although partially mediated by ART adherence, the relationship between prohibited income generation and virologic suppression was maintained in mediation analyses (Sobel statistic = -1.95, P = 0.05).

CONCLUSION

Involvement in prohibited income generation decreases the likelihood of virologic suppression directly and indirectly through its negative association with ART adherence. These findings suggest that linkages between socioeconomic marginalization, the criminalization of illicit drug use, and insufficient employment opportunities may produce barriers to access and retention in care. Programmatic and policy interventions that decrease socioeconomic vulnerability may therefore reduce HIV-related morbidity, mortality, and onward transmission.

Risk environments facing potential users of a supervised injection site in Ottawa, Canada

Background

Supervised injection sites (SISs) have been effective in reducing health risks among people who inject drugs (PWID), including those who face issues of homelessness, mental health illness, interactions with local policing practices, and HIV infection. We investigate the risk behaviours and risk environments currently faced by potential users of an SIS in Ottawa to establish the need for such a service and to contribute to the design of an SIS that can address current health risks and reduce harm.

Methods

The PROUD cohort is a community-based participatory research (CBPR) project that examines the HIV risk environment among people who use drugs in Ottawa. From March to October 2013, 593 people who reported using injection drugs or smoking crack cocaine were enrolled through street-based recruitment in the ByWard Market neighbourhood, an area of the city with a high concentration of public drug use and homelessness. Participants completed a demographic, behavioural, and risk environment questionnaire and were offered HIV point-of-care testing. We undertook descriptive and univariate analyses to estimate potential use of an SIS by PWID in Ottawa and to explore risk behaviours and features of the risk environment faced by potential users of the service.

Results

Of those participants who reported injecting drugs in the previous 12 months (n = 270), 75.2 % (203) reported a willingness to use an SIS in Ottawa. Among potential SIS users, 24.6 % had recently injected with a used needle, 19.0 % had trouble accessing new needles, 60.6 % were unstably housed, 49.8 % had been redzoned by the police, and 12.8 % were HIV positive. Participants willing to use an SIS more frequently injected in public (OR = 1.98, 95 % CI = 1.06–3.70), required assistance to inject (OR = 1.84, 95 % CI = 1.00–3.38), were hepatitis C positive (OR = 2.13, 95 % CI = 1.16–3.91), had overdosed in the previous year (OR = 2.00, 95 % CI = 1.02–3.92), and identified as LGBTQ (OR = 5.61, 95 % CI = 1.30–24.19).

Conclusion

An SIS in Ottawa would be well-positioned to reach its target group of highly marginalized PWID and reduce drug-related harms. The application of CBPR methods to a large-scale quantitative survey supported the mobilization of communities of PWID to identify and advocate for their own service needs, creating an enabling environment for harm reduction action.

Trust and people who inject drugs: The perspectives of clients and staff of Needle Syringe Programs

AIMS

Interest in health-care related trust is growing with the recognition that trust is essential for effective therapeutic encounters. While most trust-related research has been conducted with general patient groups, the experiences of people who inject drugs cannot be understood without acknowledging the critical role social stigma plays in shaping (mis)trust, both generally and in regards to health services specifically. This study examined the experiences of trust among clients and staff of Needle and Syringe Programs (NSPs) in one area of Sydney, Australia.

METHOD

In-depth interviews with 12 NSP staff and 31 NSP clients were conducted. Analysis was informed by a five component model of trust, with particular emphasis on the notion of "global trust" as encompassing experiences of stigma and other negative social processes related to injecting drug use. Participant experiences of trust in NSPs were compared with those within other drug-related health services. Particular attention was paid to understanding the relationship between 'identity' (as a drug user) and 'legitimacy' (as a service user) and the centrality of this relationship to the experience of global trust for PWID.

RESULTS

Notions of identity and legitimacy were inextricably bound up with the stigmatisation of drug use, shaping participants' experiences and accounts of trust in NSPs and drug treatment services. Client participants reported high levels of trust in NSPs, especially when compared with drug treatment services, describing being treated like "any other person" even when negotiating 'sensitive' issues. NSP staff participants described the establishment of trust as not only underpinning their work with clients but as something that required ongoing renewal and demonstration.

CONCLUSION

"Global trust" assists us to better understand the complex experiences shaping PWID decisions to engage with and trust health services. The high levels of trust reported between client and NSP need to be recognised as a valuable resource for the delivery of effective health care for people who inject drugs, including encouraging behaviours to support the prevention of blood-borne viruses.

Cessation of injecting drug use: The effects of health service utilisation, drug use and demographic factors

BACKGROUND

Injecting drug use is associated with a range of harms, however cessation of injecting is rare. There is a lack of evidence on factors associated with cessation, notably those related to health services other than drug treatment. We examined the incidence and identified longitudinal correlates of first episode of cessation in a cohort of people who inject drugs (PWID).

METHODS

Using discrete-time survival analysis, we examined correlates of the first episode of cessation (no self-reported injecting drug use in the past 12 months), including the use of health services, socio-demographics and drug-related behaviour in a cohort of PWID recruited between 2008 and 2010.

RESULTS

The cohort of 467 participants contributed 1527 person-years from recruitment to 2014. Under a fifth (17.8%) of people reported cessation of 12 months or more, yielding a cessation rate of 5.4 events per 100 person-years. Younger age (25-29 compared to 30 and above) (adjusted hazard ratio (AHR) 1.79, 95% confidence interval (CI) 1.07-3.00) and male gender (AHR 1.67, 95% CI 2.01-2.76) were positively associated with cessation, while past year use of benzodiazepines (AHR 0.45, 95% CI 0.28-0.72), arrest in the past year (AHR 0.50, 95% CI 0.30-0.83) and low SF-8 physical dimension score (AHR 0.42, 95% CI 0.20-1.88) were negatively associated with cessation. Outpatient service use had the largest effect on cessation (AHR 2.28, 95% CI 0.94-5.48, p=0.067).

CONCLUSIONS

Low rates of cessation emphasise the need for sustained and comprehensive harm reduction services. The relationship between outpatient services and cessation suggests that further research into the use in health services among PWID is warranted.

Socioeconomic marginalisation in the structural production of vulnerability to violence among people who use illicit drugs

OBJECTIVE

Many people who use illicit drugs (PWUD) face challenges to their financial stability. Resulting activities that PWUD undertake to generate income may increase their vulnerability to violence. We therefore examined the relationship between income generation and exposure to violence across a wide range of income generating activities among HIV-positive and HIV-negative PWUD living in Vancouver, Canada.

METHODS

Data were derived from cohorts of HIV-seropositive and HIV-seronegative PWUD (n=1876) between December 2005 and November 2012. We estimated the relationship between different types of income generation and suffering physical or sexual violence using bivariate and multivariate generalised estimating equations, as well as the characteristics of violent interactions.

RESULTS

Exposure to violence was reported among 977 (52%) study participants over the study period. In multivariate models controlling for sociodemographic characteristics, mental health status, and drug use patterns, violence was independently and positively associated with participation in street-based income generation activities (ie, recycling, squeegeeing and panhandling; adjusted OR (AOR)=1.39, 95% CI 1.23 to 1.57), sex work (AOR=1.23, 95% CI 1.00 to 1.50), drug dealing (AOR=1.63, 95% CI 1.44 to 1.84), and theft and other acquisitive criminal activity (AOR=1.51, 95% CI 1.27 to 1.80). Engagement in regular, self-employment or temporary employment was not associated with being exposed to violence. Strangers were the most common perpetrators of violence (46.7%) and beatings the most common type of exposure (70.8%).

CONCLUSIONS

These results suggest that economic activities expose individuals to contexts associated with social and structural vulnerability to violence. The creation of safe economic opportunities which can minimise vulnerability to violence among PWUD is therefore urgently required.

Mortality and cause of death in a cohort of people who had ever injected drugs in Glasgow: 1982-2012

BACKGROUND

To describe all-cause and cause-specific mortality in a cohort of people who had ever injected drugs (PWID) with a low prevalence of HIV over 20-30 years.

METHODS

Using a retrospective study design, identifying data from a cohort of PWID recruited between 1982 and 1993 through in-patient drug treatment services were linked to National Records for Scotland deaths data using probabilistic record linkage. We report all-cause and cause-specific mortality rates; standardized mortality ratios (SMR) across time, gender and age were estimated.

RESULTS

Among 456 PWID, 139 (30.5%) died over 9024 person-years (PY) of follow-up. Mortality within the cohort was almost nine times higher than the general population, and remained elevated across all age groups. The greatest excess mortality rate was in the youngest age group, who were 15-24 years of age (SMR 31.6, 95% CI 21.2-47.1). Drug-related deaths declined over time and mortality was significantly higher among HIV positive participants. Although SMRs declined with follow-up, the SMR of the oldest age group (45-60) was 4.5 (95% CI 3.0-6.9). There were no significant differences in all-cause mortality rates between participants who were 25 years and older at cohort entry compared to younger participants.

CONCLUSION

Mortality rates remained higher than the general population across all age groups. Screening services that identify a history of injecting drug use may be an opportunity to address risk factors faced by an ageing population of PWID and potentially have implications for future health care planning.

The impact of engagement in street-based income generation activities on stimulant drug use cessation among people who inject drugs

BACKGROUND

Despite the growing prevalence of illicit stimulant drug use internationally, and the widespread involvement of people who inject drugs (IDU) within street-based drug markets, little is known about the impact of different types of street-based income generation activities on the cessation of stimulant use among IDU.

METHODS

Data were derived from an open prospective cohort of IDU in Vancouver, Canada. We used Kaplan-Meier methods and Cox proportional hazards regression to examine the effect of different types of street-based income generation activities (e.g., sex work, drug dealing, and scavenging) on time to cessation of stimulant use.

RESULTS

Between December, 2005 and November, 2012, 887 IDU who use stimulant drugs (cocaine, crack cocaine, or crystal methamphetamine) were prospectively followed-up for a median duration of 47 months. In Kaplan-Meier analyses, compared to those who did not engage in street-based income generation activities, participants who reported sex work, drug dealing, scavenging, or more than one of these activities were significantly less likely to report stimulant drug use cessation (all p<0.001). When considered as time-updated variables and adjusted for potential confounders in a multivariable model, each type of street-based income generation activity remained significantly associated with a slower time to stimulant drug cessation (all p<0.005).

CONCLUSIONS

Our findings highlight the urgent need for strategies to address stimulant dependence, including novel pharmacotherapies. Also important, structural interventions, such as low-threshold employment opportunities, availability of supportive housing, legal reforms regarding drug use, and evidence-based approaches that reduce harm among IDU are urgently required.

'Safer environment interventions': a qualitative synthesis of the experiences and perceptions of people who inject drugs

There is growing acknowledgment that social, structural, and environmental forces produce vulnerability to health harms among people who inject drugs (PWID), and safer environment interventions (SEI) have been identified as critical to mitigating the impacts of these contextual forces on drug-related harm. To date, however, SEIs have been under-theorized in the literature, and how they minimize drug-related risks across intervention types and settings has not been adequately examined. This article presents findings from a systematic review and meta-synthesis of qualitative studies reporting PWID's experiences with three types of SEIs (syringe exchange programmes, supervised injection facilities and peer-based harm reduction interventions) published between 1997 and 2012. This meta-synthesis sought to develop a comprehensive understanding of SEIs informed by the experiences of PWID. Twenty-nine papers representing twenty-one unique studies that included an aggregate of more than 800 PWID were included in this meta-synthesis. This meta-synthesis found that SEIs fostered social and physical environments that mitigated drug-related harms and increased access to social and material resources. Specifically, SEIs: (1) provided refuge from street-based drug scenes; (2) enabled safer injecting by reshaping the social and environmental contexts of injection drug use; (3) mediated access to resources and health care services; and, (4) were constrained by drug prohibition and law enforcement activities. These findings indicate that it is critical to situate SEIs in relation to the lived experiences of PWID, and in particular provide broader environmental support to PWID. Given that existing drug laws limit the effectiveness of interventions, drug policy reforms are needed to enable public health, and specifically SEIs, to occupy a more prominent role in the response to injection drug use.

"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

People who require help injecting are disproportionately vulnerable to drug-related harm, including HIV transmission. North America's only sanctioned SIF operates in Vancouver, Canada under an exemption to federal drug laws, which imposes operating regulations prohibiting assisted injections. In response, the Vancouver Area Network of Drug Users (VANDU) launched a peer-run unsanctioned SIF in which trained peer volunteers provide assisted injections to increase the coverage of supervised injection services and minimize drug-related harm. We undertook qualitative interviews (n = 23) and ethnographic observation (50 h) to explore how this facility shaped assisted injection practices. Findings indicated that VANDU reshaped the social, structural, and spatial contexts of assisted injection practices in a manner that minimized HIV and other health risks, while allowing people who require help injecting to escape drug scene violence. Findings underscore the need for changes to regulatory frameworks governing SIFs to ensure that they accommodate people who require help injecting.

Employment predicts decreased mortality among HIV-seropositive illicit drug users in a setting of universal HIV care

OBJECTIVE

Given the link between employment and mortality in the general population, we sought to assess this relationship among HIV-positive people who use illicit drugs in Vancouver, Canada.

METHODS

Data were derived from a prospective cohort study of HIV seropositive people who use illicit drugs (n=666) during the period of May 1996-June 2010 linked to comprehensive clinical data in Vancouver, Canada, a setting where HIV care is delivered without charge. We estimated the relationship between employment and mortality using proportional hazards survival analysis, adjusting for relevant behavioural, clinical, social and socioeconomic factors.

RESULTS

In a multivariate survival model, a time-updated measure of full time, temporary or self-employment compared with no employment was significantly associated with a lower risk of death (adjusted HR=0.44, 95% CI 0.22 to 0.91). Results were robust to adjustment for relevant confounders, including age, injection and non-injection drug use, plasma viral load and baseline CD4 T-cell count.

CONCLUSIONS

These findings suggest that employment may be an important dimension of mortality risk of HIV-seropositive illicit drug users. The potentially health-promoting impacts of labour market involvement warrant further exploration given the widespread barriers to employment and persistently elevated levels of preventable mortality among this highly marginalised population.
