Negotiating structural vulnerability following regulatory changes to a provincial methadone program in Vancouver, Canada: A qualitative study

"You can't die here": an exploration of the barriers to dying-in-place for structurally vulnerable populations in an urban centre in British Columbia, Canada

BACKGROUND

One measure of quality in palliative care involves ensuring people approaching the end of life are able to receive care, and ultimately die, in the places they choose. Canadian palliative care policy directives stem from this tenet of autonomy, acknowledging that most people prefer to die at home, where they feel safe and comfortable. Limited research, however, considers the lack of 'choice' people positioned as structurally vulnerable (e.g., experiencing extreme poverty, homelessness, substance-use/criminalization, etc.) have in regard to places of care and death, with the option of dying-in-place most often denied.

METHODS

Drawing from ethnographic and participatory action research data collected during two studies that took place from 2014 to 2019 in an urban centre in British Columbia, Canada, this analysis explores barriers preventing people who experience social and structural inequity the option to die-in-place. Participants include: (1) people positioned as structurally vulnerable on a palliative trajectory; (2) their informal support persons/family caregivers (e.g., street family); (3) community service providers (e.g., housing workers, medical professionals); and (4) key informants (e.g., managers, medical directors, executive directors). Data includes observational fieldnotes, focus group and interviews transcripts. Interpretive thematic analytic techniques were employed.

RESULTS

Participants on a palliative trajectory lacked access to stable, affordable, or permanent housing, yet expressed their desire to stay 'in-place' at the end of life. Analysis reveals three main barriers impeding their 'choice' to remain in-place at the end of life: (1) Misaligned perceptions of risk and safety; (2) Challenges managing pain in the context of substance use, stigma, and discrimination; and (3) Gaps between protocols, policies, and procedures for health teams.

CONCLUSIONS

Findings demonstrate how the rhetoric of 'choice' in regard to preferred place of death is ethically problematic because experienced inequities are produced and constrained by socio-structural forces that reach beyond individuals' control. Ultimately, our findings contribute suggestions for policy, programs and practice to enhance inclusiveness in palliative care. Re-defining 'home' within palliative care, enhancing supports, education, and training for community care workers, integrating palliative approaches to care into the everyday work of non-health care providers, and acknowledging, valuing, and building upon existing relations of care can help to overcome existing barriers to delivering palliative care in various settings and increase the opportunity for all to spend their end of life in the places that they prefer.

Supervised on-site dosing in injectable opioid agonist treatment-considering the patient perspective. Findings from a cross-sectional interview study in two German cities

BACKGROUND

Injectable opioid agonist treatment (iOAT) is an effective option to support people living with opioid use disorder (OUD) who have not sufficiently benefitted from oral OAT. However, iOAT has been criticised based on theoretical and practical grounds for its dosing policies: Current regulations demand supervised, on-site application and require patients to frequently visit their treatment facility. The current study aims to investigate how patients experience on-site application and derive strategies to enhance the acceptability and effectiveness of iOAT-delivery.

METHODS

This article is based on semi-structured interviews with 27 individuals currently or previously in iOAT in two German outpatient iOAT-clinics. We undertook an inductive qualitative content analysis, which included blinded, independent coding and the analysis of individual cases.

RESULTS

Comments regarding on-site application and daily visits to the clinic were grouped into positive and negative aspects, iOAT as the best alternative option, facilitators of daily visits, and suggestions for improvement. Positive aspects took the factors stability and social support in regard. Negative aspects ranged from general inconveniences to major impediments to individuals' daily lives and towards achieving psychosocial goals. Participants reported rigorous adherence to iOAT's treatment regime, often due to a perceived lack of alternative options. Meeting iOAT's demands was eased by the patients' coping-strategies and through facilitating measures implemented by iOAT-clinics. Despite acknowledgement of the potential detriments from easing regulations, take-home arrangements were frequently suggested by participants to improve iOAT.

CONCLUSIONS

Being required to attend the clinic for supervised iOAT-application is not experienced uniformly. While clinics can support their patients to cope with strict regulations, alternative approaches to iOAT-application should be considered to accommodate patients' individual needs. Examples from other treatment modalities (e.g., remote supervision and delivery services) might aid to reconcile individualisation while providing adequate safety measures and improve iOAT in the long term.

Deimplementation in the provision of opioid agonist treatment to achieve equity of care for people engaged in treatment: a qualitative study

BACKGROUND

Deimplementation, the removal or reduction of potentially hazardous approaches to care, is key to progressing social equity in health. While the benefits of opioid agonist treatment (OAT) are well-evidenced, wide variability in the provision of treatment attenuates positive outcomes. During the COVID-19 pandemic, OAT services deimplemented aspects of provision which had long been central to treatment in Australia; supervised dosing, urine drug screening, and frequent in-person attendance for review. This analysis explored how providers considered social inequity in health of patients in the deimplementation of restrictive OAT provision during the COVID-19 pandemic.

METHODS

Between August and December 2020, semi-structured interviews were conducted with 29 OAT providers in Australia. Codes relating to the social determinants of client retention in OAT were clustered according to how providers considered deimplementation in relation to social inequities. Normalisation Process Theory was then used to analyse the clusters in relation to how providers understood their work during the COVID-19 pandemic as responding to systemic issues that condition OAT access.

RESULTS

We explored four overarching themes based on constructs from Normalisation Process Theory: adaptive execution, cognitive participation, normative restructuring, and sustainment. Accounts of adaptive execution demonstrated tensions between providers' conceptions of equity and patient autonomy. Cognitive participation and normative restructuring were integral to the workability of rapid and drastic changes within the OAT services. Key transformative actors included communities of practice and "thought leaders" who had long supported deimplementation for more humane care. At this early stage of the pandemic, providers had already begun to consider how this period could inform sustainment of deimplementation. When considering a future, post-pandemic period, several providers expressed discomfort at operating with "evidence-enough" and called for narrowly defined types of data on adverse events (e.g. overdose) and expert consensus on takeaway doses.

CONCLUSIONS

The possibilities for achieving social equity in health are limited by the divergent treatment goals of providers and people receiving OAT. Sustained and equitable deimplementation of obtrusive aspects of OAT provision require co-created treatment goals, patient-centred monitoring and evaluation, and access to a supportive community of practice for providers.

Building care amid navigating liability risks: The possibility of policy-driven care in China's drug-control arena

For Chinese policymakers, shouldering responsibility is often associated with high liability risk, thus resulting in low-level care for risky and stigmatized populations such as drug users. Therefore, it is crucial to explore ways to improve care access in such an uneasy policy environment. Based on long-term ethnographic fieldwork conducted in Yunnan province in southwestern China from 2013 to 2021, this paper traces the policy-making process of the Yunnan Province Methadone Oral Solution Take-Home Treatment Work Proposal. All stakeholders involved considered this policy attempt "impossible" at first, as the highly addictive methadone becomes an illegal drug once it is taken outside a clinical setting. By analyzing how a group of local government officials, together with medical practitioners and drug users, strive to legitimize and ultimately implement the policy, I argue that people's concern over liability risks strengthens the boundary between methadone as a "drug" and methadone as a "medicine," between methadone solution drinkers as "drug users" and as "patients," and between "inside the clinic" and "outside the clinic." By utilizing a culturalist approach to explore the possibility of care in such a context, this paper reveals that a "heqing heli hefa worthy-of-being-cared-for" discourse is crucial in that it acts as symbolic capital to dissolve the above boundaries embedded in the dominant political culture. Moreover, it is the key cultural logic of the "building" of care. The findings also illustrate how local policymakers negotiate and balance responsibility and liability to create a potential policy space for enabling care practices. Additionally, this study sheds light on the inclusion of care for the most stigmatized and marginalized populations, and has broad implications for policy-making in other contexts.

Suboptimal nonmedical qualities of primary care linked with care avoidance among people who use drugs in a Canadian setting amid an integrated health care reform

BACKGROUND

People who use unregulated drugs (PWUD) often face significant barriers to-and thereby avoid seeking-health care. In Vancouver, Canada, a neighborhood-wide health care system reform began in 2016 to improve health care delivery and quality. In the wake of this reform, we sought to determine the prevalence of health care avoidance and its association with emergency department use among PWUD in this setting and examine patient-reported nonmedical qualities of health care ("responsiveness").

METHODS

The study derived data from two prospective cohort studies of community-recruited PWUD in Vancouver in 2017-18. Responsiveness was ascertained by the World Health Organizations' standardized measurements and we evaluated seven domains of responsiveness (dignity, autonomy, communication, confidentiality, prompt attention, choice of provider, and quality of basic amenities). The study used Pearson chi-squared test to examine differences in responsiveness between those who did and did not avoid care. The study team used multivariable logistic regression to determine the relationship between care avoidance due to past mistreatment and emergency department use, adjusting for potential confounders.

RESULTS

Among 889 participants, 520 (58.5%) were male, 204 (22.9%) reported avoiding health care, most commonly for chronic pain (47.4%). Overall, 6.6% to 36.2% reported suboptimal levels (i.e., not always meeting the expected quality) across all seven measured domain of responsiveness. Proportions reporting suboptimal qualities were significantly higher among those who avoided care than those who did not across all domains, including care as soon as wanted (51.0% vs. 31.8%), listened to carefully (44.1% vs. 20.4%), and involved in health care decision-making (27.9% vs. 12.7%) (all p < 0.05). In multivariable analyses, avoidance of health care was independently associated with self-reported emergency department use (adjusted odds ratio = 1.49; 95% confidence interval:1.01-2.19).

CONCLUSION

We found that almost a quarter of our sample of PWUD avoided seeking health care due to past mistreatment, and all seven measured domains of responsiveness were suboptimal and linked with avoidance. Individuals who reported avoidance of health care were significantly more likely to report emergency department use. Multi-level interventions are needed to remedy the suboptimal qualities of health care and thereby reduce care avoidance.

Policy actor views on structural vulnerability in harm reduction and policymaking for illegal drugs: A qualitative study

BACKGROUND

Health risks associated with drug use are concentrated amongst structurally vulnerable people who use illegal drugs (PWUD). We described how Canadian policy actors view structural vulnerability in relation to harm reduction and policymaking for illegal drugs, and what solutions they suggest to reduce structural vulnerability for PWUD.

METHODS

The Canadian Harm Reduction Policy Project is a mixed-method, multiple case study. The qualitative component included 73 semi-structured interviews conducted with harm reduction policy actors across Canada's 13 provinces and territories between November 2016 and December 2017. Interviews explored perspectives on harm reduction and illegal drug policies and the conditions that facilitate or constrain policy change. Our sub-analysis utilized a two-step inductive analytic process. First, we identified transcript segments that discussed structural vulnerability or analogous terms. Second, we conducted latent content analysis on the identified excerpts to generate main findings.

RESULTS

The central role of structural vulnerability (including poverty, unstable/lack of housing, racialization) in driving harm for PWUD was acknowledged by participants in all provinces and territories. Criminalization, in particular, was seen as a major contributor to structural vulnerability by justifying formal and informal sanctions against drug use and, by extension, PWUD. Many participants expressed that their personal understanding of harm reduction included addressing the structural conditions facing PWUD, yet identified that formal government harm reduction policies focused solely on drug use rather than structural factors. Participants identified several potential policy solutions to intervene on structural vulnerability including decriminalization, safer supply, and enacting policies encompassing all health and social sectors.

CONCLUSIONS

Structural vulnerability is salient within Canadian policy actors' discourses; however, formal government policies are seen as falling short of addressing the structural conditions of PWUD. Decriminalization and safer supply have the potential to mitigate immediate structural vulnerability of PWUD while policies evolve to advance social, economic, and cultural equity.

The effect of a methadone reformulation on opioid agonist treatment outcomes: A population-based study in British Columbia, Canada, 2013-14

INTRODUCTION

The province of British Columbia, Canada, changed the existing oral anhydrous methadone solution to a 10-times more concentrated pre-mixed solution, Methadose®, on February 1, 2014. We aimed to assess the immediate effects of the methadone reformulation on missed doses, days off methadone, changes in medication dosing and dispensations of opioids for pain, and hospitalizations and mortality among all people receiving treatment at or near the time of the change.

METHODS

We conducted a population-based retrospective cohort study including all individuals receiving at least one methadone dispensation in the 12 months prior to the study period. We executed a difference-in-differences analysis by estimating a multivariate regression model to compare outcomes in the three months before and after the reformulation (November 1, 2013 to April 30, 2014) versus a time-lagged control cohort with similar characteristics observed during an equivalent nonoverlapping interval. We used daily individual-level linked health administrative data capturing missed doses, days off methadone, changes in methadone dosing, concurrent dispensations of opioids for pain, hospitalizations, and mortality. We stratified the cohorts into three subgroups: (i) those receiving OAT for ≥12 months; (ii) those receiving OAT for <12 months; and (iii) those not receiving OAT at the start of the study period. We conducted sensitivity analyses and placebo tests to assess the robustness of our results.

RESULTS

Among the 16,339 individuals receiving methadone during the study period, the reformulation was associated with more instances of methadone dose increases (34.5% [95% Confidence Interval (CI): 27.4%, 41.5%]). For those retained in treatment ≥12 months prior to the study period (n = 7449), the reformulation was associated with more instances of methadone dose increases (50.2% [39.5%, 60.8%]) and dispensations of opioids for pain (62.2% [40.8%, 83.5%]), as well as an increase in missed doses (41.9% [29.1%, 54.7%]) and days off methadone (62.6% [39.7%, 85.4%]). We found no statistically significant change in risk of hospitalization or mortality. Sensitivity analyses supported our results.

CONCLUSION

Our results reinforce the need expressed by people receiving methadone for greater client involvement in the planning and implementation of regulatory changes that may impact client care, especially those patients with a relatively long treatment history.

Development and validation of health system performance measures for opioid use disorder in British Columbia, Canada

BACKGROUND

Performance measurement provides an evidence-based means to inform development of interventions to improve the quality of care for people who use opioids. We aimed to develop and assess the predictive validity of health system performance measures for opioid use disorder (OUD) in British Columbia (BC), Canada.

METHODS

Performance measures were generated using retrospective population-level administrative datasets (both provincial and regional) and publicly-reported retrospective data according to four domains (care engagement, clinical guideline compliance, integration, and healthcare utilization). The adjusted odds ratio was estimated via generalized linear mixed models to determine predictive validity for all-cause hospitalization or mortality within 6 months of measurement.

FINDINGS

A total of 102 performance measures were constructed. We identified 55,470 diagnosed PWOUD, and 39,456 ever engaged in opioid agonist treatment (OAT). We found divergent rates of treatment for concurrent conditions (7.4% for alcohol use disorder to 80.1% for HIV/AIDS), low levels of linkage to OAT and other outpatient care following acute care, and increasing levels of service provision, including increases in OAT prescribers and pharmacies, naloxone kit distribution and overdose prevention site visitation. Our analyses on the predictive validity measures largely supported a priori hypotheses on the direction of effect on the outcome.

CONCLUSIONS

We identified a range of priorities to improve the quality of care for PWOUD, with critical gaps in linkage to care through acute care settings and long-term engagement in OAT. The proposed measures can be derived for geographic and clinical subgroups and updated over time, providing a basis to monitor and evaluate efforts to address the public health burden of OUD.

Structural violence and the need for compassionate use of methadone in Mexico

BACKGROUND

Epidemiological data from Mexico have documented an increase in heroin use in the last decade. However, there is no comprehensive care strategy for heroin users, especially those who have been accused of a crime. The objective of this study was to describe the heroin and methadone use of intravenous heroin users of both sexes who have been in jail, to offer evidence for the formulation of health policy.

METHODS

This study used an ethnographic approach, with open-ended interviews carried out from 2014 to the present. Heroin users of both sexes attending a private methadone clinic in Mexico City were invited to participate. The sample was non-probabilistic. All interviews were audiotaped and transcribed, and narratives were analyzed using thematic analysis.

RESULTS

Participants in this study were 33 users of heroin, two of them women, who had been in prison. They ranged in age from 33 to 62 years, had used heroin for a period of 13-30 years, and were from three states: Michoacan, Oaxaca, and Mexico City. Three principal categories of analysis were structured: 1. Pilgrimage for help (dynamics of the drama of suffering, pain, and time through health care spaces); 2) methadone use as self-care; and 3) accessibility to methadone treatment. The impossibility of access to methadone treatment is a condition which motivates users in their journey. The dynamics of methadone use are interpreted as a form of self-care and care to avoid substance use. Reducing the psychological, physical, and harmful effects of the substance allows them to perform daily activities. The inability to access treatment leads to a significant effect on users who experience structural violence.

CONCLUSION

Compassionate methadone treatment and holistic attention should be considered as a way to meet patients' needs and mitigate their suffering, based on public health policy that allows for human rights-based care.

Rationalities of Space and Drug-Related Harms: Accounts of People Who Inject Drugs in Nigeria

BACKGROUND

Studies have examined how people who inject drugs (PWID) navigate public spaces for drug consumption, but little is known about consumption of drugs in private apartments. This study explores social, structural and physical environment factors influencing injecting practices and the rationalities shaping how PWID make decisions about where to consume drugs.

METHODS

The study is based on qualitative data from 41 in-depth interviews conducted with both homeless and housed PWID recruited through snowball sampling in Uyo, Nigeria. Thematic analysis, framed by the theoretical constructs of structural and everyday violence, and situated rationality theories, was undertaken on transcripts.

RESULTS

Analysis revealed different socio-spatial rationalities underlying decisions about where to use drugs: avoidance of police arrest, convenience and relaxation, avoidance of drug sharing, avoidance of drug-scene violence, and stigma and shame. These factors show the impacts of social, structural and physical environment factors on the lived experiences of PWID. Injecting in private apartments potentially offset the risk of stigma, police arrest and violence linked to public injecting, but increase the risk of overdose and sharing of drugs and needle-syringes based on social relations of trust.

CONCLUSIONS

Findings show that PWID chose between competing risks when deciding on where to inject drugs. Interventions should consider the situated contexts of risk, and adapt harm reduction measures to the risk profile of different populations of PWID.

Component Processes of Decision Making in a Community Sample of Precariously Housed Persons: Associations With Learning and Memory, and Health-Risk Behaviors

The Iowa Gambling Task (IGT) is a widely used measure of decision making, but its value in signifying behaviors associated with adverse, "real-world" consequences has not been consistently demonstrated in persons who are precariously housed or homeless. Studies evaluating the ecological validity of the IGT have primarily relied on traditional IGT scores. However, computational modeling derives underlying component processes of the IGT, which capture specific facets of decision making that may be more closely related to engagement in behaviors associated with negative consequences. This study employed the Prospect Valence Learning (PVL) model to decompose IGT performance into component processes in 294 precariously housed community residents with substance use disorders. Results revealed a predominant focus on gains and a lack of sensitivity to losses in these vulnerable community residents. Hypothesized associations were not detected between component processes and self-reported health-risk behaviors. These findings provide insight into the processes underlying decision making in a vulnerable substance-using population and highlight the challenge of linking specific decision making processes to "real-world" behaviors.

"People need them or else they're going to take fentanyl and die": A qualitative study examining the 'problem' of prescription opioid diversion during an overdose epidemic

The practice of prescription opioid (PO) diversion remains highly controversial and has been characterized as a source of significant drug-related harm by physicians and public health officials. We critically analyze the "problem" of diversion through an examination of the perspectives of people who divert POs during an overdose epidemic to better understand the practice, including benefits and challenges, as well as how diversion is shaped by structural contexts. Qualitative semi-structured interviews were conducted with 21 participants recruited from ongoing cohort studies involving people who use drugs in Vancouver, Canada. Prohibitive prescribing policies made accessing POs difficult, leading some to smuggle drugs out of clinics. Others would buy POs in bulk or do trades to acquire them. Participants risked having their prescriptions terminated, but rationalized this risk as a protective measure that allows them to provide safer drugs to others (e.g., to prevent overdose or treat withdrawal). Poverty also framed diversion, with some participants diverting their POs to generate income to pay for expenses including food and sometimes illicit fentanyl (perceived as a stronger alternative). However, diversion was shaped by other constraints, including criminalization, negative health impacts from not consistently consuming POs, and supplies running out, which led some participants to rely on other illegal means to generate income. This study highlights the intricate means by which POs are acquired and diverted and how environmental contexts frame how participants negotiated risk and rationalized diversion. Our study provides an alternative perspective on the "problem" of diversion and demonstrate a positive effect in providing a safer drug supply to others during an overdose crisis. Given that drug policy, criminalization, and poverty created challenges, our findings demonstrate the need for strategies that engender greater safety, reduce harm, and alleviate the effects of these constraints, including through policies promoting safer drug supplies, decriminalization, and employment.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

The relationship between opioid agonist therapy satisfaction and fentanyl exposure in a Canadian setting

Background

While patient-reported treatment dissatisfaction is considered an important factor in determining the success of substance use disorder treatment, the levels of dissatisfaction with opioid agonist therapies (OAT) and its relationship with the risk of fentanyl exposure have not been characterized in the context of the ongoing opioid overdose crisis in the US and Canada. Our primary hypothesis was that OAT dissatisfaction was associated with an increased odds of fentanyl exposure.

Methods

Our objective was to examine self-reported treatment satisfaction among OAT patients in Vancouver, Canada and the association with fentanyl exposure. Longitudinal data were derived from 804 participants on OAT enrolled in two community-recruited harmonized prospective cohort studies of people who use drugs in Vancouver between 2016 and 2018 via semi-annual interviews and urine drug screens (UDS). We employed multivariable generalized estimating equations to examine the relationship between OAT dissatisfaction and fentanyl exposure.

Results

Out of 804 participants (57.0% male), 222 (27.6%) reported being dissatisfied with OAT at baseline and 1070 out of 1930 observations (55.4%) had fentanyl exposure. The distribution of OAT reported in the sample was methadone (n = 692, 77.7%), buprenorphine-naloxone (n = 82, 9.2%), injectable OAT (i.e., diacetylmorphine or hydromorphone; (n = 65, 7.3%), slow-release oral morphine (n = 44, 4.9%) and other/study medication (n = 8, 1.0%). In the multivariable analysis, OAT dissatisfaction was positively associated with fentanyl exposure (AOR = 1.34; 95% CI: 1.08–1.66).

Conclusions

A substantial proportion of OAT patients in our sample reported dissatisfaction with their OAT, and more than half were exposed to fentanyl. We also found that those who were dissatisfied with their OAT were more likely to be exposed to fentanyl. These findings demonstrate the importance of optimizing OAT satisfaction in the context of the ongoing opioid overdose crisis.

Homelessness Is Socially Created: Cluster Analysis of Social Determinants of Homelessness (SODH) in North West England in 2020

Poverty creates social conditions that increase the likelihood of homelessness. These include exposure to traumatic life experiences; social disadvantages such as poor educational experiences; being raised in a broken family, care homes or foster care; physical, emotional, and sexual abuse; and neglect at an early age. These conditions reduce people’s ability to negotiate through life challenges. This cross-sectional study documents the clustering and frequency of adverse social conditions among 152 homeless people from four cities in North West England between January and August 2020. Two-step cluster analysis showed that having parents with a criminal record, care history, and child neglect/abuse history was predictive of homelessness. The cluster of indicator variables among homeless people included sexual abuse (χ2 (N = 152) = 220.684, p < 0.001, Cramer’s V = 0.7), inappropriate sexual behaviour (χ2 (N = 152) = 207.737, p < 0.001, Cramer’s V = 0.7), emotional neglect (χ2 (N = 152) = 181.671, p < 0.001, Cramer’s V = 0.7), physical abuse by step-parent (χ2 (N = 152) = 195.882, p < 0.001, Cramer’s V = 0.8), and physical neglect (χ2 (N = 152) = 205.632, p < 0.001, Cramer’s V = 0.8). Poverty and homelessness are intertwined because of the high prevalence of poverty among the homeless. Poverty sets up a chain of interactions between social conditions that increase the likelihood of unfavourable outcomes: homelessness is at the end of the interaction chain. Interventions supporting families to rise out of poverty may also reduce entry into homelessness.

A qualitative investigation of HIV treatment dispensing models and impacts on adherence among people living with HIV who use drugs

Antiretroviral therapy (ART) dispensing is strongly associated with treatment adherence. Among illicit drug-using populations, whom experience greater structural barriers to adherence, directly administered antiretroviral therapy (DAAT) is often regarded as a stronger predictor of optimal adherence over self-administered medications. In Vancouver, Canada, people living with HIV (PLHIV) who use drugs and live in low-income housing are a critical population for treatment support. This group is typically able to access two key DAAT models, daily delivery and daily pickup, in addition to ART self-administration. This ethno-epidemiological qualitative study explores how key dispensing models impact ART adherence among PLHIV who use drugs living in low-income housing, and how this is framed by structural vulnerability. Semi-structured interviews lasting 30-45 minutes were conducted between February and May 2018 with 31 PLHIV who use drugs recruited from an ongoing prospective cohort of PLHIV who use drugs. Interviews were audio-recorded, transcribed verbatim, and analyzed using QSR International's NVivo 12 software. Interviews focused on housing, drug use, and HIV management. Models that constrained agency were found to have negative impacts on adherence and quality of life. Treatment interruptions were framed by structural vulnerabilities (e.g., housing vulnerability) that impacted ability to maintain adherence under certain dispensing models, and led participants to consider other models. Participants using DAAT models which accounted for their structural vulnerabilities (e.g., mobility issues, housing instability), credited these models for their treatment adherence, but also acknowledged factors that constrained agency, and the negative impacts this could have on both adherence, and quality of life. Being able to integrate ART into an established routine is key to supporting ART adherence. ART models that account for the structural vulnerability of PLHIV who use drugs and live in low-income housing are necessary and housing-based supports could be critical, but the impacts of such models on agency must be considered to ensure optimal adherence.

Understanding concurrent stimulant use among people on methadone: A qualitative study

INTRODUCTION AND AIMS

Opioid-related overdoses are an epidemic in North America, prompting a greater use of medications for opioid use disorder, such as methadone. Although many people work toward overall drug abstinence while on methadone, a sub-population of people with and without histories of polysubstance use engage in stimulant use while on methadone treatment. This study explores motivations for concurrent stimulant and methadone use in a street-involved drug-using population.

DESIGN AND METHODS

Semi-structured qualitative interviews were conducted with 39 people on methadone in Vancouver, Canada. Participants were recruited from among the participants in two community-based prospective cohort studies consisting of HIV-positive and HIV-negative people who use drugs. Interview transcripts were analysed using an inductive and iterative approach.

RESULTS

Our analysis identified three primary themes. First, participants articulated how stimulants were used to counter the sedating effects of methadone and enable them to engage in daily and survival activities (e.g. income generation). Second, participants described increased stimulant use to compensate for reduced stimulant intoxication while taking methadone. Finally, participants described the desire to achieve intoxication on stimulants once stable on methadone, as their substance use treatment goals did not involve drug abstinence.

DISCUSSION AND CONCLUSION

Among a street-involved drug-using population in which people do not have abstinence-based treatment goals, there are several functional reasons to use stimulants concurrently while on methadone. A deeper and more nuanced understanding of substance use motivators may contribute to further research and inform policy and guideline changes that support low threshold and harm reduction-focused methadone treatment programs and other interventions to reduce drug-related harms.

Caregiving at the margins: An ethnographic exploration of family caregivers experiences providing care for structurally vulnerable populations at the end-of-life

BACKGROUND

People experiencing structural vulnerability (e.g. homelessness, poverty, racism, criminalization of illicit drug use and mental health stigma) face significant barriers to accessing care at the end-of-life. 'Family' caregivers have the potential to play critical roles in providing care to these populations, yet little is known regarding 'who' caregivers are in this context and what their experiences may be.

AIM

To describe family caregiving in the context of structural vulnerability, to understand who these caregivers are, and the unique challenges, burdens and barriers they face.

DESIGN

Critical ethnography.

SETTING/PARTICIPANTS

Twenty-five family caregivers participated. Observational fieldnotes and semi-structured interviews were conducted in home, shelter, transitional housing, clinic, hospital, palliative care unit, community-based service centre and outdoor settings.

RESULTS

Family caregivers were found to be living within the constraints of structural vulnerability themselves, with almost half being street family or friends. The type of care provided varied greatly and included tasks associated with meeting the needs of basic survival (e.g. finding food and shelter). Thematic analysis revealed three core themes regarding experiences: Caregiving in the context of (1) poverty and substance use; (2) housing instability and (3) challenging relationships.

CONCLUSION

Findings offer novel insight into the experiences of family caregiving in the context of structural vulnerability. Engaging with family caregivers emerged as a missing and necessary palliative care practice, confirming the need to re-evaluate palliative care models and acknowledge issues of trust to create culturally relevant approaches for successful interventions. More research examining how 'family' is defined in this context is needed.

Not what the doctor ordered: Motivations for nonmedical prescription drug use among people who use illegal drugs

BACKGROUND

Nonmedical Prescription Drug Use (NMPDU) is common among people who use illegal drugs. NMPDU is particularly problematic among this population however, as medications such as benzodiazepines and gabapentinoids can potentiate the harmful effects of opioids. Despite these harms, there is some evidence that NMPDU can have harm reducing and therapeutic potential for some people who use illegal drugs. This study provides further evidence of the harm reducing motives for NMPDU among people who use illegal drugs in community and prison settings in Wales, UK.

METHODS

In depth, semi-structured interviews were conducted with 60 interviewees recruited from statutory and third sector drug treatment providers operating in five towns and cities in Wales, and from two Welsh prisons. Eligibility was based primarily on whether the person was currently (or previously) a user of illegal drugs and had recent experience of NMPDU.

RESULTS

NMPDU was found to be largely driven by insufficient access to certain prescription medications and treatment. In this context, NMPDU played an important role in alleviating legitimate medical concerns and overcoming logistical and regulatory barriers associated with Opioid Substitution Therapy. NMPDU also had everyday practicality and mitigated many of the everyday harms experienced by people who use drugs, including opioid withdrawal and stimulant comedowns.

CONCLUSION

Results suggest that NMPDU has the potential to mitigate a number of legitimate medical concerns in the absence of treatment. Finding nuanced ways of responding to patient need whilst reducing the potential for NMPDU are therefore needed, and harm reduction strategies that harness the knowledge and expertise of people who use drugs should be encouraged. Additional policy measures that attend to the inequities and social-structural factors that produce and maintain the need to consume prescription medications in ways that are not intended are also required.

"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.

Slow release oral morphine versus methadone for opioid use disorder in the fentanyl era (pRESTO): Protocol for a non-inferiority randomized clinical trial

BACKGROUND

North America is facing an unprecedented public health crisis of opioid-related morbidity and mortality, increasingly as a result of the introduction of illicitly manufactured fentanyl into the street drug market. Although the treatment of opioid use disorder (OUD) is a key element in the response to the opioid overdose epidemic, currently available pharmacotherapies (e.g., methadone, buprenorphine) may not be acceptable to or effective in all patients. Available evidence suggests that slow-release oral morphine (SROM) has similar efficacy rates as methadone with respect to promoting abstinence, and with improvements in a number of patient-reported outcomes among persons using heroin. However, little is known about the relative effectiveness and acceptability of SROM compared to methadone in the context of fentanyl use. This study aims to address this research gap.

METHODS

pRESTO is a 24-week, open-label, two arm, non-inferiority, randomized controlled trial comparing SROM versus methadone for the treatment of OUD. Participants will be 298 clinically stable, non-pregnant adults with OUD, recruited from outpatient clinics in Vancouver, Canada, where the majority of the illicit opioids are contaminated with fentanyl. The primary outcome is suppression of illicit opioid use, measured by bi-weekly urine drug screens. Secondary outcomes include: treatment retention, medication safety, overdose events, treatment satisfaction, psychological functioning, changes in drug-related problems, changes in quality of life, opioid cravings, other substance use, and cost-effectiveness.

DISCUSSION

pRESTO will be among the first studies to evaluate treatment options for individuals primarily using synthetic street opioids, providing important evidence to guide treatment strategies for this population.

Trajectories of retention in opioid agonist therapy in a Canadian setting

BACKGROUND

Long-term engagement in opioid agonist therapy (OAT) has been consistently associated with reduced risk for morbidity and mortality in people with opioid use disorder (OUD). However, the dynamic nature of engagement/disengagement in OUD care for over time is poorly captured by traditional metrics. We characterized long-term longitudinal trajectories of engagement in OAT in Vancouver, Canada, between 2005 and 2018.

METHODS

Data were derived from two community-recruited prospective cohorts of people who use drugs. Retention in OAT was defined as self-reported enrolment in OAT for two consecutive follow-up periods (an approximately six-month retention interval). We used latent class growth analysis to identify OAT engagement trajectories during the first five years after OAT initiation and multivariable logistic regression to evaluate predictors of trajectory group membership.

RESULTS

We identified four OAT retention trajectories among 438 OAT initiators: "consistently high" (36%), "consistently low" (23%), "increasing" (23%), and "decreasing" (15%). Employment was a significant cross-cutting predictor of membership of all sub-optimal OAT engagement patterns compared to consistently high trajectories. We also found that initiating OAT after 2014 (when regulatory changes to the provincial OAT program were introduced) was associated with the "consistently low" engagement group relative to others.

CONCLUSIONS

We identified four distinct OAT engagement trajectories in Vancouver, Canada, with employment being a common predictor of sub-optimal care trajectories, suggesting the need to explore alternative OAT models to address employment-related barriers. Care trajectory analysis could help inform tailored interventions to specific populations of people with OUD at specific time points to improve engagement in OAT, and decrease opioid-related morbidity and mortality.

Willingness to take buprenorphine/naloxone among people who use opioids in Vancouver, Canada

OBJECTIVES

Opioid agonist therapy is the cornerstone of treatment of opioid use disorder. In Canada, buprenorphine/naloxone has recently been adopted as the first line agonist therapy given its comparable effectiveness to methadone and superior safety profile. This study examines factors associated with willingness to take buprenorphine/naloxone among opioid users.

METHODS

Data were derived from two prospective cohorts of high-risk individuals who use drugs in Vancouver, Canada. Multivariable logistic regression analyses were used to determine factors associated with willingness to use buprenorphine/naloxone among people who use opioids and were not currently accessing this treatment option. Participants who were unwilling to use buprenorphine/naloxone were invited to provide reason(s) and their responses were examined in a sub-analysis.

RESULTS

Between December 2014 and May 2018, 1103 participants were interviewed. Overall, 194 (17.6%) respondents indicated that they would be willing to take buprenorphine/naloxone. Variables independently associated with willingness were previous buprenorphine/naloxone treatment (adjusted odds ratio [AOR] = 2.04), having ever used methadone treatment (AOR = 1.87), and age (AOR = 0.98, per year older) (all p < 0.05). Satisfaction with current agonist therapy (25.4%), not knowing what buprenorphine/naloxone is (25.1%), and wanting more information about buprenorphine/naloxone (15.1%) were the most commonly cited reasons for unwillingness. A low rate of willingness to use buprenorphine/naloxone (15.1%) was also observed among the sub-set of participants not using methadone.

CONCLUSIONS

While an overall low level of willingness to take buprenorphine/naloxone was observed, this appeared to be largely driven by satisfaction with other agonists and a low prevalence of community knowledge about buprenorphine/naloxone.

Being at the Bottom Rung of the Ladder in an Unequal Society: A Qualitative Analysis of Stories of People without a Home

Background: Homelessness is rising in the United Kingdom, despite investment in measures to eradicate it made by the government and charity organisations. Aim: The aim is to examine the stories of homeless people in order to document their perceptions of their social status, the reasons that led to their homelessness, and propose a conceptual explanation. Method: We conducted 26 semi-structured interviews in three centres for homeless people in Cheshire, North West of England. Results: Three categories-education, employment, and health-emerged from the data and provided a theoretical explanation for the reasons that led to their homelessness. These are vital not only for the successful negotiation of one's way out of homelessness, but also for achieving other social goods, including social connections, social mobility, and engaging in positive social relationships. Conclusion: Participants catalogued the adverse childhood experiences, which they believe limited their capacity to meaningfully engage with the social institution for social goods, such as education, social services, and institutions of employment. Since not all people who have misfortunes of poor education, poor health, and loss of job end up being homeless, we contend that a combination of these with multiple adverse childhood experiences may have weakened their resilience to traumatic life changes, such as loss of job and poor health.

Disadvantaged and disenfranchised in bereavement: A scoping review of social and structural inequity following expected death

An emphasis on individual intervention and psychological complexity has characterised research on bereavement following an experience of life-limiting illness. Exploration of "structural vulnerability" as a positionality produced by social and structural inequity could provide insights into areas of practice and policy in need of development. This scoping review sought to summarise published research on experiences of social and structural inequities in the context of bereavement due to life-limiting illness. Underpinned by recognised methodological frameworks, systematic searches were conducted of four electronic databases. Eligible studies attended to bereavement experience following the death of an adult due to life-limiting illness, included consideration of social and structural inequities, and were undertaken in high income countries between 1990 and 2018. Following thematic analysis, a conceptual framework was developed. Of 322 records, 62 full text articles were retrieved and 15 papers met inclusion criteria. Studies highlighted unequal social status in bereavement related to gender, class, sexuality, ethnicity and age, with structural inequity experienced in interactions with institutions and social networks. Studies also identified that the experience of bereavement itself may be accompanied by exposure to disenfranchising systems and processes. Structural vulnerability appeared to be associated with outcomes including psychological distress, social disenfranchisement and practical concerns such as financial strain, housing insecurity and employment issues. Social and structural inequities potentially contribute to layered and patterned experiences of disadvantage and disenfranchisement following expected death, with implications for individual agency. Findings point to the need for consideration of socio-ecological approaches within and beyond specialist palliative care, involving development of more responsive social policy, coordinated advocacy, and systemic capacity building regarding experiences of grief, to better support populations positioned as structurally vulnerable in bereavement.

The intersectional risk environment of people who use drugs

Current conceptual models for examining the production of risk and harm (e.g. syndemics, 'risk environment') in substance use research have been fundamental in emphasizing broader environmental factors that shape health outcomes for people who use drugs (PWUD). However, the application of these frameworks in ways that highlight nuance and complexity has remained challenging, with much of this research focusing on select social positions (e.g. race, gender) and social-structural factors (e.g. poverty, drug policies). It is crucial that we move to better accounting for these relations in the context of substance use research to enhance equity in research and ensure understanding of diverse and complex needs. Building on the risk environment framework and complementary approaches, this article introduces the 'intersectional risk environment' as an approach to understanding the interconnected ways that social locations converge within the risk environment to produce or mitigate drug-related outcomes. This framework integrates a relational intersectional lens to examine how differential outcomes across populations of PWUD are produced in relation to social location and processes operating across social-structural dimensions. In doing so, the intersectional risk environment highlights how outcomes are products of processes and relations that are embodied, reflected, and challenged while situated within social, historical, and geographic contexts. Incorporating this framework into future research may improve understandings of health outcomes for PWUD and better orient structural interventions and public health approaches to address differential risks and experiences of PWUD.

"We don't got that kind of time, man. We're trying to get high!": Exploring potential use of drug checking technologies among structurally vulnerable people who use drugs

BACKGROUND

Novel public health interventions are being considered to address the opioid overdose epidemic, including drug checking technologies. We examined the willingness to use various drug checking technologies among structurally-vulnerable people who use drugs (PWUD).

METHODS

We conducted one-to-one qualitative semi-structured interviews with 20 PWUD in Vancouver, Canada's Downtown Eastside. Participants were purposively recruited from ongoing cohort studies of PWUD.

RESULTS

Overall willingness to use drug checking technologies was low among participants. A range of factors undermined potential use of various drug checking technologies including: having to give up a drug sample; time dedication; discrepancies regarding measurements and accuracy; recourse following positive fentanyl results; ambivalence to overdose risk; and availability and accessibility of drug checking technologies.

CONCLUSIONS

Participants discussed numerous factors that undermined potential willingness to use drug checking technologies. These factors underscore the structural vulnerabilities experienced by PWUD and how they may constrain uptake of drug checking technologies. Future drug checking programming should consider these influencing factors prior to the implementation of drug checking technologies to ensure that drug checking interventions are appropriate and meeting the needs of target populations.

Exploring new and existing PrEP modalities among female sex workers and women who inject drugs in a U.S. city

To address a shortage in research on Pre-Exposure Prophylaxis (PrEP) amongst women at high risk of HIV acquisition, this study explored the attitudes and preferences of female sex workers (FSW) (n = 15) and women who inject drugs (WWID) (n = 16) to existing (e.g., pill) and new (e.g., injection, implant) PrEP modalities, in Baltimore, Maryland, U.S.A. This study reports on seven focus groups conducted between December 2016 and April 2017 and aims to provide new insights into FSW and WWID attitudes and preferences towards three different PrEP delivery methods (i.e., PrEP pill, PrEP implant, PrEP injection). Results draw upon the PrEP care continuum framework and distill existing factors, including lack of control over side effects with new, longer lasting modalities, better privacy with injections, increased adherence with reduced dosing schedules from longer lasting PrEP and new factors such as perceptibility concerns with respect to the PrEP implant relevant to PrEP uptake and adherence among two important overlapping, at-risk populations. The study contributes to a better understanding of barriers and facilitators to uptake and adherence for FSW and WWID around both existing and new PrEP modalities, with implications for future clinical trials and PrEP interventions with at risk-populations.

"Just too busy living in the moment and surviving": barriers to accessing health care for structurally vulnerable populations at end-of-life

BACKGROUND

Despite access to quality care at the end-of-life (EOL) being considered a human right, it is not equitable, with many facing significant barriers. Most research examines access to EOL care for homogenous 'normative' populations, and as a result, the experiences of those with differing social positioning remain unheard. For example, populations experiencing structural vulnerability, who are situated along the lower rungs of social hierarchies of power (e.g., poor, homeless) will have unique EOL care needs and face unique barriers when accessing care. However, little research examines these barriers for people experiencing life-limiting illnesses and structural vulnerabilities. The purpose of this study was to identify barriers to accessing care among structurally vulnerable people at EOL.

METHODS

Ethnography informed by the critical theoretical perspectives of equity and social justice was employed. This research drew on 30 months of ethnographic data collection (i.e., observations, interviews) with structurally vulnerable people, their support persons, and service providers. Three hundred hours of observation were conducted in homes, shelters, transitional housing units, community-based service centres, on the street, and at health care appointments. The constant comparative method was used with data collection and analysis occurring concurrently.

RESULTS

Five significant barriers to accessing care at EOL were identified, namely: (1) The survival imperative; (2) The normalization of dying; (3) The problem of identification; (4) Professional risk and safety management; and (5) The cracks of a 'silo-ed' care system. Together, findings unveil inequities in accessing care at EOL and emphasize how those who do not fit the 'normative' palliative-patient population type, for whom palliative care programs and policies are currently built, face significant access barriers.

CONCLUSIONS

Findings contribute a nuanced understanding of the needs of and barriers experienced by those who are both structurally vulnerable and facing a life-limiting illness. Such insights make visible gaps in service provision and provide information for service providers, and policy decision-makers alike, on ways to enhance the equitable provision of EOL care for all populations.

"It's about bloody time": Perceptions of people who use drugs regarding drug law reform

BACKGROUND

In Australia and elsewhere, the impacts of drug prohibition have sparked a critical dialogue about the state of current drug laws. While a range of 'experts' have offered their opinion and participation in these deliberations, the voices of the affected community have largely been excluded. This study aimed to gather the opinions and preferences of people who use drugs about the current or alternative models of drug laws, in addition to how they think drug laws could be changed Author Conflict of Interest Declaration.

METHODS

In March 2018, four focus groups (n = 37) were conducted with people who were in receipt of social welfare services in Sydney, Australia, where participants were encouraged to share their views about the current drug laws, drug law reform options, and important messages to politicians. Several themes were identified through a thematic analysis.

RESULTS

Models of drug law reform were often understood and expressed in language and constructs different to those commonly used by researchers. Opinions were diverse and there was no consensus on a preferred model, although discussions flowed around decriminalisation, legalisation, and a medical/prescription model; the latter being the preferred approach. Participants shared pessimistic views of the drug laws ever changing, and argued that public opinion would need to adjust for reform to succeed. Furthermore, they argued that the views of the affected community are vital to any drug law reform campaign.

CONCLUSIONS

Participants affinity towards a medical/prescription approach to drug regulation was an unexpected finding. This study serves as an important example of the opinions and experiential knowledge of the affected community and this knowledge could be solicited alongside other forms of 'expertise' in drug law reform campaigns.

An age-based analysis of nonmedical prescription opioid use among people who use illegal drugs in Vancouver, Canada

BACKGROUND

Nonmedical prescription opioid use (NMPOU) is a serious public health problem in North America. At a population-level, previous research has identified differences in the prevalence and correlates of NMPOU among younger versus older age groups; however, less is known about age-related differences in NMPOU among people who use illegal drugs.

METHODS

Data were collected between 2013 and 2015 from two linked prospective cohort studies in Vancouver, Canada: the At-Risk Youth Study (ARYS) and the Vancouver Injection Drug Users Study (VIDUS). Factors independently associated with NMPOU among younger (ARYS) and older (VIDUS) participants were examined separately using bivariate and multivariate generalized estimating equations.

RESULTS

A total of 1162 participants were included. Among 405 eligible younger participants (Median age = 25; Inter-Quartile Range [IQR]: 22-28), 40% (n = 160) reported engaging in NMPOU at baseline; among 757 older participants (Median age = 48, IQR: 40-55), 35% (n = 262) reported engaging in NMPOU at baseline. In separate multivariate analyses of younger and older participants, NMPOU was positively and independently associated with heroin use (younger: Adjusted Odds Ratio [AOR] = 3.12, 95% Confidence Interval [CI]: 2.08-4.68; older: AOR = 2.79, 95% CI: 2.08-3.74), drug dealing (younger: AOR = 2.22, 95% CI: 1.58-3.13; older: AOR = 1.87, 95% CI: 1.40-2.49), and difficulty accessing services (younger: AOR = 1.47, 95% CI: 1.04-2.09; older: AOR = 1.74, 95% CI: 1.32-2.29). Among the youth cohort only, NMPOU was associated with younger age (AOR = 1.12, 95% CI: 1.05-1.19), crack use (AOR = 1.56, 95% CI: 1.06-2.30), and binge drug use (AOR = 1.41, 95% CI: 1.00-1.97); older participants who engaged in NMPOU were more likely to report crystal methamphetamine use (AOR = 1.97, 95% CI: 1.46-2.66), non-fatal overdose (AOR = 1.76, 95% CI: 1.20-2.60) and sex work (AOR = 1.49, 95% CI: 1.00-2.22).

DISCUSSION

The prevalence of NMPOU is similar among younger and older people who use drugs, and independently associated with markers of vulnerability among both age groups. Adults who engage in NMPOU are at risk for non-fatal overdose, which highlights the need for youth and adult-specific strategies to address NMPOU that include better access to health and social services, as well as a range of addiction treatment options for opioid use. Findings also underscore the importance of improving pain treatment strategies tailored for PWUD.

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.

Trends in engagement in the cascade of care for opioid use disorder, Vancouver, Canada, 2006-2016

BACKGROUND

A cascade of care framework has been proposed to identify and address implementation gaps in addiction medicine. Using this framework, we characterized temporal trends in engagement in care for opioid use disorder (OUD) in Vancouver, Canada.

METHODS

Using data from two cohorts of people who use drugs, we assessed the yearly proportion of daily opioid users achieving four sequential stages of the OUD cascade of care [linkage to addiction care; linkage to opioid agonist treatment (OAT); retention in OAT; and stability] between 2006 and 2016. We evaluated temporal trends of cascade indicators, adjusting for socio-demographic characteristics, HIV/HCV status, substance use patterns, and social-structural exposures.

RESULTS

We included 1615 daily opioid users. Between 2006 and 2016, we observed improvements in linkage to care (from 73.2% to 78.9%, p = <0.001), linkage to (from 69.2% to 70.6%, p = 0.011) and retention in OAT (from 29.1% to 35.5%, p = <0.001), and stability (from 10.4% to 17.1%, p = <0.001). In adjusted analyses, later calendar year of observation was associated with increased odds of linkage to care (Adjusted Odds Ratio [AOR] = 1.02, 95% Confidence Interval [CI]: 1.01-1.04), retention in OAT (AOR 1.02, 95% CI: 1.01-1.04) and stability (AOR = 1.03, 95% CI: 1.01-1.05), but not with linkage to OAT (AOR 1.00, 95% CI: 0.98-1.01).

CONCLUSIONS

Temporal improvements in OUD cascade of care indicators were observed. However, only a third of participants were retained in OAT in 2016. These findings suggest the need for novel approaches to improve engagement in care for OUD to address the escalating opioid-related overdose crisis.

Negotiating space & drug use in emergency shelters with peer witness injection programs within the context of an overdose crisis: A qualitative study

Vancouver, Canada is experiencing an overdose crisis due to the proliferation of fentanyl and related analogues and novel overdose response interventions are being implemented across multiple high overdose risk environments, including emergency shelters. We draw on ethnographic fieldwork and qualitative interviews to examine how social, structural, and physical contexts at two emergency shelters implementing a peer-based supervised injection intervention influenced injection drug use and overdose risks. Findings reveal that the implementation of this intervention reduced stigma and shame through the normalization of drug use in shelter spaces, and yet underlying social norms and material constraints led people to inject alone in non-designated injecting spaces. Whereas these spatial dynamics of injection drug use potentially increased overdose vulnerability, an emerging sense of collective responsibility in relation to the overdose crisis led to the routinization of peer witnessing practices across the shelter environment to extend the impact of the intervention.

A fragmented code: The moral and structural context for providing assistance with injection drug use initiation in San Diego, USA

BACKGROUND

Injection drug use initiation is shaped by social networks and structural contexts, with people who inject drugs often assisting in this process. We sought to explore the norms and contexts linked to assisting others to initiate injection drug use in San Diego, USA, to inform the development of structural interventions to prevent this phenomenon.

METHODS

We undertook qualitative interviews with a purposive sample of people who inject drugs and had reported assisting others to initiate injection (n = 17) and a sub-sample of people who inject drugs (n = 4) who had not reported initiating others to triangulate accounts. We analyzed data thematically and abductively.

RESULTS

Respondents' accounts of providing initiation assistance were consistent with themes and motives reported in other contexts: of seeking to reduce harm to the 'initiate', responding to requests for help, fostering pleasure, accessing resources, and claims that initiation assistance was unintentional. We developed analysis of these themes to explore initiation assistance as governed by a 'moral code'. We delineate a fragmented moral code which includes a range of meanings and social contexts that shape initiation assistance. We also show how assistance is happening within a structural context that limits discussion of injection drug use, reflecting a prevailing silence on drug use linked to stigma and criminalization.

CONCLUSIONS

In San Diego, the assistance of others to initiate injection drug use is governed by a fragmented moral code situated within particular social norms and contexts. Interventions that address the social and structural conditions shaped by and shaping this code may be beneficial, in tandem with efforts to support safe injection and the reduction of injection-related harms.

The Syndemic of Opioid Misuse, Overdose, HCV, and HIV: Structural-Level Causes and Interventions

PURPOSE OF REVIEW

This article reviews the case for recognizing (1) the epidemics of opioid misuse, overdose, hepatitis C virus, and HIV as a syndemic and (2) the importance of examining and addressing structural factors in responses to this syndemic. We focus on the current syndemic in the US, but also consider data from other locations to highlight the issues existing and arising in various contexts.

RECENT FINDINGS

Advances in multi-level theory and statistical methods allow sound ecologic and multi-level analyses of the impact of structural factors on the syndemic. Studies of opioid misuse, overdoses, hepatitis C virus, and HIV demonstrate that area-level access to healthcare, medication-assisted treatment of opioid use disorders, sterile injection equipment, and overdose prevention with naloxone, as well as factors such as opioid marketing, income inequality, intensity of policing activities, and health care policies, are related to the prevalence of substance misuse, overdoses, infection risk, and morbidity. Structural variables can predict area-level vulnerability to the syndemic. The implementation of combined prevention and treatment interventions can control and reverse components of the syndemic. Recognizing and monitoring potent structural factors can facilitate the identification of areas at risk of vulnerability to the syndemic. Further, many structural factors are modifiable through intervention and policy to reduce structural vulnerability and create health-enabling environments. Evidence supports the immediate implementation of broader HCV and HIV testing and substance use screening, medication-assisted treatment, needle/syringe exchange programs, naloxone programs, increased population-level implementation of HCV treatment, and further attention to structural-level factors predicting, and contributing to, area-level vulnerability, such as degrees of opioid marketing, distribution, and prescribing.

Death Is a Social Justice Issue: Perspectives on Equity-Informed Palliative Care

All too often, palliative care services are not responsive to the needs of those who are doubly vulnerable, being that they are both in need of palliative care services and experiencing deficits in the social determinants of health that result in complex, intersecting health and social concerns. In this article, we argue for a reorientation of palliative care to explicitly integrate the premises of health equity. We articulate the philosophical, theoretical, and empirical scaffolding required for equity-informed palliative care and draw on a current study to illustrate such an approach to the care of people who experience structural vulnerabilities.

Prevalence of Heavy Alcohol Use Among People Receiving Methadone Following Change to Methadose

BACKGROUND

A recent switch in methadone formulation from methadone (1 mg/mL) to Methadose (10 mg/mL) in British Columbia (BC), Canada, was associated with increased reports of opioid withdrawal and increases in illicit opioid use. Impacts on other forms of drug use have not been assessed. Since alcohol use is common among people receiving Medication-Assisted Treatment (MAT), we assessed if switch was associated with increased prevalence of heavy alcohol use.

METHODS

Drawing on data from two open prospective cohort studies of people who inject drugs in Vancouver, BC, generalized estimating equations (GEE) model examined relationship between methadone formulation change and heavy alcohol use, defined by National Institute for Alcohol Abuse and Alcoholism (NIAAA). A sub-analysis examined relationship with heavier drinking defined as at least eight drinks per day on average in last six months.

RESULTS

Between June 2013 and May 2015, a total of 787 participants on methadone were eligible for the present analysis, of which 123 (15.6%) reported heavy drinking at least once in last six months. In an unadjusted GEE model, Methadose use was not significantly associated with an increased likelihood of heavy drinking [Odds Ratio (OR) = 1.03; 95% Confidence interval (CI) = 0.87-1.21]. Methadose use was not significantly associated with an increased likelihood of drinking at least eight drinks daily on average (OR = 1.09, 95% CI = 0.72-1.65).

CONCLUSIONS

Despite reported changes in opioid use patterns coinciding with the change, there appeared to be no effect of the methadone formulation change on heavy drinking in this setting.

The experience of initiating injection drug use and its social context: a qualitative systematic review and thematic synthesis

BACKGROUND AND AIM

Understanding the experience of initiating injection drug use and its social contexts is crucial to inform efforts to prevent transitions into this mode of drug consumption and support harm reduction. We reviewed and synthesized existing qualitative scientific literature systematically to identify the socio-structural contexts for, and experiences of, the initiation of injection drug use.

METHODS

We searched six databases (Medline, Embase, PsychINFO, CINAHL, IBSS and SSCI) systematically, along with a manual search, including key journals and subject experts. Peer-reviewed studies were included if they qualitatively explored experiences of or socio-structural contexts for injection drug use initiation. A thematic synthesis approach was used to identify descriptive and analytical themes throughout studies.

RESULTS

From 1731 initial results, 41 studies reporting data from 1996 participants were included. We developed eight descriptive themes and two analytical (higher-order) themes. The first analytical theme focused on injecting initiation resulting from a social process enabled and constrained by socio-structural factors: social networks and individual interactions, socialization into drug-using identities and choices enabled and constrained by social context all combine to produce processes of injection initiation. The second analytical theme addressed pathways that explore varying meanings attached to injection initiation and how they link to social context: seeking pleasure, responses to increasing tolerance to drugs, securing belonging and identity and coping with pain and trauma.

CONCLUSIONS

Qualitative research shows that injection drug use initiation has varying and distinct meanings for individuals involved and is a dynamic process shaped by social and structural factors. Interventions should therefore respond to the socio-structural influences on injecting drug use initiation by seeking to modify the contexts for initiation, rather than solely prioritizing the reduction of individual harms through behavior change.

Unintended impacts of regulatory changes to British Columbia Methadone Maintenance Program on addiction and HIV-related outcomes: An interrupted time series analysis

BACKGROUND

In February 2014, several regulatory reforms were introduced to the methadone maintenance treatment (MMT) program in British Columbia, Canada, including a switch to a ten-times more concentrated methadone formulation and restrictions in pharmacy delivery services. We evaluated possible unintended effects of these changes on illicit drug use patterns and HIV treatment outcomes among HIV-positive opioid users.

METHODS

Data was drawn from ACCESS, a prospective community-recruited cohort of HIV-positive people who use illicit drugs in Vancouver, Canada. Interrupted Time Series Analyses were used to evaluate impacts of the policy change on monthly rates of MMT enrolment, illicit heroin injection, antiretroviral therapy (ART) adherence, and HIV viral suppression among HIV-positive opioid users between November 2012 and May 2015.

RESULTS

A total of 331 HIV-positive opioid users were included. The MMT policy change led to a significant immediate 11.5% increase in heroin injection, and 15.9% drop in optimal ART adherence. A gradual increase in the prevalence of MMT enrolment after the policy change was also documented (0.9% per month). No changes in viral suppression rates were observed.

CONCLUSION

We observed immediate increases in illicit heroin injection and decreases in ART adherence in the wake of regulatory changes to the local MMT program. These findings underscore the need to consider potential unintended effects of altering health programmes for vulnerable populations, the need to develop appropriate mitigation strategies, as well as to involve all relevant stakeholders in the planning and implementations of new policies.

Social-structural factors influencing periods of injection cessation among marginalized youth who inject drugs in Vancouver, Canada: an ethno-epidemiological study

BACKGROUND

Injection drug use is associated with HIV and hepatitis C transmission, overdose, and other preventable harms. These harms are heightened for structurally vulnerable injection drug-using populations, as their social conditions pose barriers to safer injecting. Previous research on injection cessation has largely focused on adult drug-using populations. Little qualitative work has examined the social, structural, and environmental factors that shape periods of injection cessation among youth and young adults. Such research is essential to understanding how we can best reduce harms among this vulnerable population as they move in and out of periods of injection cessation.

METHODS

We conducted 22 semi-structured, qualitative interviews with street-involved young people who use drugs (SY), focused on characterizing their transitions into periods of injection cessation and perceived barriers to injection cessation. Adopting an ethno-epidemiological approach, participants who had experienced at least 6 months of injection cessation were purposively recruited from an ongoing prospective cohort study of SY in Vancouver, Canada to participate in qualitative interviews. Qualitative interview findings were triangulated with the findings of a longitudinal program of ethnographic research with SY in this setting. This ethno-epidemiological approach allowed for a more robust exploration of contextual factors surrounding drug use patterns than would be possible through traditional epidemiological methods alone.

RESULTS

Findings indicate that periods of injection cessation were influenced by access to harm reduction-informed youth-focused services, transitions in route of administration (e.g., from injecting methamphetamine to the smoking of methamphetamine), and the provision of housing and social supports (e.g., from friends, family, and care providers). Conversely, participants indicated that inadequate social supports and, for some, abstinence-focused treatment methods (e.g., 12-step programs), impeded efforts to cease injecting.

CONCLUSIONS

To reduce harms, it is imperative to reorient attention toward the social, structural, and spatial contexts that surround injection drug use and shape periods of injection cessation for SY. There is an urgent need for more comprehensive youth-focused services for those engaged in injection drug use, and further study of innovative means of engaging youth.

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.

Antiretroviral Therapy Interruption Among HIV Postive People Who Use Drugs in a Setting with a Community-Wide HIV Treatment-as-Prevention Initiative

HIV Treatment as Prevention (TasP) initiatives promote antiretroviral therapy (ART) access and optimal adherence (≥95 %) to produce viral suppression among people living with HIV (PLHIV) and prevent the onward transmission of HIV. ART treatment interruptions are common among PLHIV who use drugs and undermine the effectiveness of TasP. Semi-structured interviews were conducted with 39 PLHIV who use drugs who had experienced treatment ART interruptions in a setting with a community-wide TasP initiative (Vancouver, Canada) to examine influences on these outcomes. While study participants attributed ART interruptions to "treatment fatigue," our analysis revealed individual, social, and structural influences on these events, including: (1) prior adverse ART-related experiences among those with long-term treatment histories; (2) experiences of social isolation; and, (3) breakdowns in the continuity of HIV care following disruptive events (e.g., eviction, incarceration). Findings reconceptualise 'treatment fatigue' by focusing attention on its underlying mechanisms, while demonstrating the need for comprehensive structural reforms and targeted interventions to optimize TasP among drug-using PLHIV.

"We're giving you something so we get something in return": Perspectives on research participation and compensation among people living with HIV who use drugs

BACKGROUND

Compensation for participating in research has been a fundamental element of the research apparatus despite concerns about its impact on incentivising participation. Researchers and research ethics boards acknowledge that compensation may prompt structurally vulnerable populations, such as people who use drugs (PWUD), to engage in research primarily out of financial need. Thus, institutional restrictions around compensation have been implemented. This study explores the ethical implications of compensation practices aimed at 'protecting' structurally vulnerable people living with HIV (PLHIV) who use drugs within the context of individuals' lived realities.

METHODS

We draw on five focus groups conducted in 2011 with 25 PLHIV who use drugs and access a community-based HIV care facility in Vancouver, Canada. This analysis focused on participants' perceptions of research compensation, which became the central point of discussion in each group.

RESULTS

Participants viewed research as a transactional process through which they could challenge the underpinnings of bioethics and bargain for compensation. Research compensation was thus critical to attracting participants and positioned as a 'legitimate' form of income. Participants' medicalised identities, specifically living with HIV, were fundamental to justifying compensation. The type of compensation (e.g. gift card, cash) also significantly impacted whether participants were fully compensated and, at times, served to exacerbate their structural vulnerability.

CONCLUSION

Research compensation is critical in shaping structurally vulnerable populations' participation and experiences with research and can further marginalize individuals. Practices surrounding research compensation, particularly for drug-using and HIV-positive populations, need to be evaluated to ensure participants are equitably compensated for the expertise they provide.

Plasma HIV-1 RNA viral load rebound among people who inject drugs receiving antiretroviral therapy (ART) in a Canadian setting: an ethno-epidemiological study

Background

People who inject drugs (PWID) living with HIV often experience sub-optimal antiretroviral therapy (ART) treatment outcomes, including HIV plasma viral load (PVL) rebound. While previous studies have identified risk factors for PVL rebound among PWID, no study has examined the perspectives of PWID who have experienced PVL rebound episodes. We conducted an ethno-epidemiological study to investigate the circumstances surrounding the emergence of rebound episodes among PWID in Vancouver, BC, Canada.

Methods

Comprehensive clinical records linked to a community-based prospective observational cohort of HIV-positive drug users were used to identify PWID who had recently experienced viral rebound. In-depth qualitative interviews with 16 male and 11 female participants explored participant perspectives regarding the emergence of viral rebound. A timeline depicting each participant’s HIV viral load and adherence to ART was used to elicit discussion of circumstances surrounding viral rebound.

Findings

Viral rebound episodes were shaped by interplay between various individual, social, and environmental factors that disrupted routines facilitating adherence. Structural-environmental influences resulting in non-adherence included housing transitions, changes in drug use patterns and intense drug scene involvement, and inadequate care for co-morbid health conditions. Social-environmental influences on ART adherence included poor interactions between care providers and patients producing non-adherence, and understandings of HIV treatment that fostered intentional treatment discontinuation.

Conclusions

This study describes key pathways which led to rebound episodes among PWID receiving ART and illustrates how environmental forces may increase vulnerability for non-adherence leading to treatment failure. Our findings have potential to help inform interventions and supports that address social-structural forces that foster non-adherence among PWID.
