A Qualitative Analysis of Hospitalist Perceptions of Self-Directed Discharge Among Inpatients with Opioid Use Disorder.

Background: People with opioid use disorder (OUD) have high rates of hospital admissions and high rates of patient-directed discharge, leading to significant morbidity and mortality. In this study, we aimed to understand hospitalist attitudes toward patients with OUD leaving before treatment completion and their willingness to collaborate with patients in future initiatives focused on improving the experience of hospital-based care for patients with OUD. Methods: We conducted semi-structured interviews with hospitalists at two hospitals in Philadelphia, PA to explore their perspectives on social and structural factors that contribute to patients with OUD leaving the hospital before treatment completion. Interviews were recorded, transcribed, and coded with NVivo using conventional content analysis. Results: Twenty-two hospitalists (64% female, 72.7% White, mean age 37) were interviewed between February and April 2021. Hospitalists listed the following as reasons for patients with OUD leaving before treatment completion: untimely and inadequate pain/withdrawal treatment, limited prescribing options in medications for OUD, restrictive visitor and smoking policies, and patient social and other obligations. Twenty out of 22 hospitalists were willing to engage in collaborative patient-centered care but noted institutional barriers. Conclusion: Hospitalists stated willingness to collaborate with patients on identifying and developing systems-level solutions that would allow for patient-centered care. In-hospital access to addiction consult service, staff with lived experience, and other culturally competent resources are key to reducing self-directed discharge, as is training to address stigma and reframe perceptions of appropriate dosing for pain and withdrawal. Hospitalists note a need for transitions to outpatient care after hospital discharge.

"We're already doing this work": ethical research with community-based organizations.

BACKGROUND: Public health research frequently relies on collaborations with community-based organizations, and these partnerships can be essential to the success of a project. However, while public health ethics and oversight policies have historically focused on ensuring that individual subjects are protected from unethical or unfair practices, there are few guidelines to protect the organizations which facilitate relationships with - and are frequently composed of - these same vulnerable populations. As universities, governments, and donors place a renewed emphasis on the need for community engaged research to address systematic drivers of health inequity, it is vital that the ways in which research is conducted does not uphold the same intersecting systems of gender, race, and class oppression which led to the very same health inequities of interest. METHODS: To understand how traditional notions of public health research ethics might be expanded to encompass partnerships with organizations as well as individuals, we conducted qualitative interviews with 39 staff members (executive directors and frontline) at community-based organizations that primarily serve people who use drugs, Black men who have sex with men, and sex workers across the United States from January 2016 - August 2017. We also conducted 11 in-depth interviews with professional academic researchers with experience partnering with CBOs that serve similar populations. Transcripts were analyzed thematically using emergent codes and a priori codes derived from the Belmont Report. RESULTS: The concepts of respect, beneficence, and justice are a starting point for collaboration with CBOs, but participants deepened them beyond traditional regulatory concepts to consider the ethics of relationships, care, and solidarity. These concepts could and should apply to the treatment of organizations that participate in research just as they apply to individual human subjects, although their implementation will differ when applied to CBOs vs individual human subjects. CONCLUSIONS: Academic-CBO partnerships are likely to be more successful for both academics and CBOs if academic researchers work to center individual-level relationship building that is mutually respectful and grounded in cultural humility. More support from academic institutions and ethical oversight entities can enable more ethically grounded relationships between academic researchers, academic institutions, and community based organizations.

Overdose Prevention and Housing: a Qualitative Study Examining Drug Use, Overdose Risk, and Access to Safer Supply in Permanent Supportive Housing in Vancouver, Canada.

The majority of overdose deaths in British Columbia (BC) occur among people using illicit substances alone in private residences. Some supportive housing in BC includes on-site access to a variety of health and substance use-related services. More recently, a number of supportive housing locations have started offering prescribed safer supply medications to people at high overdose risk, though these remain limited and under-evaluated. In this study, we describe the drug use practices - including access to and use of on-site supervised consumption, OAT, and prescribed safer supply medications - of study participants living in permanent supportive housing with integrated primary care, substance use treatment services, and supervised consumption spaces. Qualitative interviews were conducted with 30 residents of a permanent supportive housing site in Vancouver, Canada. Data were analyzed using a sequential process to identify both a priori (e.g., low-barrier substance use treatment, pandemic effects on service access) and emerging themes (e.g., using alone). Most (N = 27) study participants reported using alone in their rooms, despite having access to an on-site supervised consumption area. Reasons for using alone include the following: preference for being alone, discretion/stigma, and restrictive housing policies. Less than half (N = 12) of the study participants accessed on-site prescribed safer supply medications. Participants receiving on-site prescribed safer supply described positive benefits including reduced use of illicit opioids, and less reliance on illicit income generation activities. On-site prescribed safer supply programs within supportive housing environments are an important tool in addressing overdose risk.

Naloxone protection, social support, network characteristics, and overdose experiences among a cohort of people who use illicit opioids in New York City.

BACKGROUND: Despite increased availability of take-home naloxone, many people who use opioids do so in unprotected contexts, with no other person who might administer naloxone present, increasing the likelihood that an overdose will result in death. Thus, there is a social nature to being "protected" from overdose mortality, which highlights the importance of identifying background factors that promote access to protective social networks among people who use opioids. METHODS: We used respondent-driven sampling to recruit adults residing in New York City who reported recent (past 3-day) nonmedical opioid use (n = 575). Participants completed a baseline assessment that included past 30-day measures of substance use, overdose experiences, and number of "protected" opioid use events, defined as involving naloxone and the presence of another person who could administer it, as well as measures of network characteristics and social support. We used modified Poisson regression with robust variance to estimate unadjusted and adjusted prevalence ratios (PRs) and 95% confidence intervals (CIs). RESULTS: 66% of participants had ever been trained to administer naloxone, 18% had used it in the past three months, and 32% had experienced a recent overdose (past 30 days). During recent opioid use events, 64% reported never having naloxone and a person to administer present. This was more common among those: aged ≥ 50 years (PR: 1.18 (CI 1.03, 1.34); who identified as non-Hispanic Black (PR: 1.27 (CI 1.05, 1.53); experienced higher levels of stigma consciousness (PR: 1.13 (CI 1.00, 1.28); and with small social networks (< 5 persons) (APR: 1.14 (CI 0.98, 1.31). Having a recent overdose experience was associated with severe opioid use disorder (PR: 2.45 (CI 1.49, 4.04), suicidality (PR: 1.72 (CI 1.19, 2.49), depression (PR: 1.54 (CI 1.20, 1.98) and positive urinalysis result for benzodiazepines (PR: 1.56 (CI 1.23, 1.96), but not with network size. CONCLUSIONS: Results show considerable gaps in naloxone protection among people who use opioids, with more vulnerable and historically disadvantaged subpopulations less likely to be protected. Larger social networks of people who use opioids may be an important resource to curtail overdose mortality, but more effort is needed to harness the protective aspects of social networks.

Factors Associated With Calling 911 for an Overdose: An Ethnographic Decision Tree Modeling Approach.

Objectives. To identify factors that influence when people who use drugs (PWUDs) call 911 for an overdose. Methods. We conducted 45 qualitative interviews and 180 surveys with PWUDs who had recently witnessed overdoses in Southern California from 2017 to 2019. We used conditional inference tree and random forest models to generate and validate a model to predict whether 911 would be called. Results. Our model had good in- (83%) and out-of-sample (84%) predictive accuracy. Three aspects of the social and policy environment influenced calling 911 for an overdose: the effectiveness of response strategies employed, the behavior of other bystanders, and whether the responder believes it is their responsibility to call. Conclusions. Even in the presence of policies that provide some protections, PWUDs are faced with difficult decisions about calling 911 and must weigh their own safety against that of an overdose victim. Potential interventions include strengthening training and safety planning for PWUDs, bolstering protections for PWUDs when they call 911, and separating law enforcement response from emergency medical response to overdoses.

Xylazine detected in unregulated opioids and drug administration equipment in Toronto, Canada: clinical and social implications.

BACKGROUND: The North American opioid overdose crisis is driven in large part by the presence of unknown psychoactive adulterants in the dynamic, unregulated drug supply. We herein report the first detection of the psychoactive veterinary compound xylazine in Toronto, the largest urban center in Canada, by the city's drug checking service. METHODS: Toronto's Drug Checking Service launched in October 2019. Between then and February 2021, 2263 samples were submitted for analysis. The service is offered voluntarily at harm reduction agencies that include supervised consumption services. Samples were analyzed using gas chromatography-mass spectrometry or liquid chromatography-high resolution mass spectrometry. Targeted and/or untargeted screens for psychoactive substances were undertaken. RESULTS: In September 2020, xylazine was first detected by Toronto's Drug Checking Service. Among samples analyzed from September 2020 to February 2021 expected to contain fentanyl in isolation (610) or in combination with methamphetamine (16), xylazine was detected in 46 samples (7.2% and 12.5% of samples, respectively). Samples were predominantly drawn from used drug equipment. Three of the samples containing xylazine (6.5%) were associated with an overdose. CONCLUSION: We present the first detection of xylazine in Toronto, North America's fourth-largest metropolitan area. The increased risk of overdose associated with use of xylazine and its detection within our setting highlights the importance of drug checking services in supporting rapid responses to the emergence of potentially harmful adulterants. These data also highlight the clinical challenges presented by the dynamic nature of unregulated drug markets and the concomitant need to establish regulatory structures to reduce their contribution to overdose morbidity and mortality.

"I Gotta Go With Modern Technology, So I'm Gonna Give 'em the Narcan": The Diffusion of Innovations and an Opioid Overdose Prevention Program.

Fatal opioid overdoses can be prevented by opioid overdose prevention programs (OOPPs). The present study qualitatively examined the diffusion process of an OOPP among 30 persons who inject drugs (PWIDs) in an opioid-saturated community. Purposive sampling was used to recruit participants into three groups based on familiarity with the OOPP. Findings revealed that participants often adopted the OOPP, which was offered by a local harm reduction organization, if first exposed by staff hosting and implementing it. Barriers to adoption included belief that OOPP training was lengthy or unnecessary, lack of perceived relative advantage, nonengagement with the host organization, and trepidation of administering withdrawal-causing medication to fellow PWIDs. Participants outside of networks diffusing the OOPP were isolated from other PWIDs. Staff from the host organization were influential in encouraging OOPP adoption, which underscores their importance in the effort to reduce fatal overdoses.

Reasons for enrolling in safer supply programs: A longitudinal qualitative study on participant goals and related outcomes in the MySafe program.

OBJECTIVE: Safer supply programs are a novel response to the ongoing overdose crisis in Canada - providing people at high overdose risk with a safer alternative to the highly toxic unregulated drug supply. The MySafe program provides pharmaceutical-grade opioids to participants via biometric dispensing machines. This study examines program-related goals and related outcomes across time. METHOD: Longitudinal semi-structured interviews were conducted with 29 study participants at baseline and one-year follow-up. Interviews covered program functionality, experiences, outcomes, and reasons for enrollment and engagement. Baseline and follow-up interviews were compared to explore changes over time, including the effectiveness of the MySafe program in supporting individuals' achievement of their stated goals. RESULTS: Most participants reported similar goals at their baseline and follow-up interviews. The most common goal for initiating and staying in the program was to stop or reduce using street-purchased drugs, followed by abstinence, and wanting to stop injecting drugs. A number of participants described goals addressing issues related to structural vulnerability (e.g., improving living situations). At follow-up, some participants reported reducing street-purchased drug use, no participants reported abstinence, and all those wanting to stop injecting drugs reported achieving their goals. CONCLUSION: Our findings highlight a strong desire among study participants to be separated from the unpredictable street-drug supply. Participants reported variable success attaining their stated goals. However, our results demonstrate the need for such programs to better attend to participant goals, especially those impacted by structural vulnerability, that can be supported with wrap-around social and health care supports.

Media framing xylazine as a "zombie drug" is amplifying stigma onto people who use drugs.

Amid increasing efforts to understand xylazine-associated harms, examining the potentially catastrophic role of stigma resulting from media outlets framing xylazine as the "zombie drug" is imperative. Zombies are cinematically depicted as soulless, dangerous, and required to be killed off entirely for public safety, making the "zombie" analogy especially grave amid the fatal overdose crisis. Xylazine is called the "zombie drug" due to its heavy sedative effect and associated-severely infected skin ulcers. We surmise that wide-scale media framing of xylazine as the "zombie drug" has increased stigmas onto people who use drugs as their likening to zombies reifies subhuman status. The present commentary highlights many media headlines and quotes that use "zombie" terminology when writing about xylazine, and examine how this expansive media framing amplifies stigmas. Xylazine's proliferation in the illicit drug market will likely increase infected ulcers needing medical attention. People who use drugs are often reluctant to seek medical care due to experiences of medically-institutionalized stigma. Based on the media's extensive depiction of xylazine as the "zombie drug," it is plausible that medical practitioners have been exposed to this stigmatizing framing, which could unknowingly detrimentally impact provision of medical care. Strategies to offset harms of xylazine-associated stigmas are proposed, including that medical practitioners undergo evidence-based training to reduce stigmatizing responses to severe xylazine-associated ulcers as any indication of enacted stigma can be internalized by the person seeking treatment, which in turn can perpetuate harms like sepsis or overdose. Author ethnographic observations of xylazine presence are included, which encompass three distinct urban settings that span North America. Finally, we suggest approaches media outlets could adopt to reflect on how referring to xylazine as the "zombie" drug amplifies stigmas onto people already surviving under structural conditions heightening physical and mental trauma, and use language instead that could aid in lessening these harms.

A qualitative assessment of tablet injectable opioid agonist therapy (TiOAT) in rural and smaller urban British Columbia, Canada: Motivations and initial impacts.

BACKGROUND: The evolving and unpredictable unregulated drug market has driven an unprecedented overdose crisis that requires effective intervention. Growing evidence suggests that novel opioid agonist treatments, such as tablet injectable opioid agonist therapy (TiOAT), have potential to prevent overdoses and other drug-related harms. More evidence is needed to characterize their utility in achieving these outcomes. The current article is an analysis of two TiOAT programs implemented in British Columbia, Canada, to assess impact on health and well-being, including overdose risk. Moreover, we explored participants' enrollment goals and if they were achieved. METHODS: The study employed qualitative methods to evaluate the TiOAT program in two sites between October 2021 and April 2022. We developed a semi-structured interview tool to guide in depth interviews. All interviews (n = 32) took place on teleconference software or in person. Thematic analysis allowed for the emergence of themes associated with TiOAT participation. RESULTS: Participants discussed various motivations for enrolling in TiOAT, which included gaining financial stability, reducing or eliminating drug use, addressing withdrawal symptoms, wanting to work, and improving social circumstances. An assessment of initial programmatic impacts revealed that many participant-identified motivators were achieved. Participants also reported fewer or no overdoses since starting TiOAT, and many reported switching from injecting to smoking drugs. Some challenges included adequate dosing as evidenced by ongoing withdrawal and pain. Some participants requested additional opioids, such as diacetylmorphine, to aid in reducing illicit drug use. CONCLUSION: Participants described how TiOAT helped them to achieve many of their goals. Suggested programmatic improvements include enhanced patient-provider co-design with respect to dosing to address ongoing withdrawal and pain. As the unpredictability the unregulated drug market worsens, novel options, such as TiOAT, ought to be implemented broadly to reduce overdose events and improve quality of life for people who use drugs.

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

BACKGROUND: In response to the ongoing overdose crisis in Canada, a number of opioid agonist treatment and safer supply programs provide people at high overdose risk with daily-dispensed tablet hydromorphone, with some requiring witnessed ingestion and others providing take-away doses. While these programs are intended to reduce overdose events by limiting people's use of the contaminated drug supply, the experiences of people receiving hydromorphone vary. In this article we explore the ways people repurpose hydromorphone to address unmet needs. METHODS: This article draws on in-depth qualitative interviews from two studies evaluating hydromorphone tablet distribution programs in British Columbia, Canada. We used thematic analysis to identify themes related to repurposing hydromorphone. We compared themes across the two studies to identify any similarities or differences in relation to the ways study participants discussed repurposing hydromorphone tablets. We utilize vignettes - snapshots of participant experiences - to analyse and represent the data. RESULTS: Four vignettes demonstrate how hydromorphone tablets are often being used to address and resolve unmet needs of people who use drugs. While most participants reported reducing their use of illicit drugs, a variety of instrumental uses of tablet hydromorphone were also discussed, including reducing anxiety, addressing sleep issues, withdrawal management, and managing chronic pain. CONCLUSION: Our findings demonstrate how people who use drugs are maximizing the benefits of tablet hydromorphone distribution to address unmet needs. Hydromorphone distribution programs represent a public health and harm reduction intervention that is usefully addressing experiences related to structural vulnerabilities (such as inadequate pain management), which are often overlooked amongst stigmatized groups.

'I'm on the coast and I'm on methadone': A qualitative study examining access to opioid agonist treatment in rural and coastal British Columbia.

INTRODUCTION: Despite rural regions being disproportionately impacted by the toxic drug supply, little is known about the contextual factors influencing access to opioid agonist treatment (OAT) specific to rural residents. The present study examines these factors in a rural and coastal setting in British Columbia, Canada. METHODS: The qualitative methods were used to examine the barriers and facilitators to OAT access. Between July and October 2021, semi-structured interviews were conducted with people who use drugs who reside in a rural and coastal community. Thematic analysis was used to identify emergent themes and subthemes. Results were corroborated by the research team and a local community advisory board. RESULTS: Twenty-seven (n = 27) participants described both limiting and facilitating factors that influenced OAT accessibility. Access was less challenging when participants' OAT dispensing pharmacy was in close proximity, had extended hours of operation, or when pharmacies provided delivery services. Barriers to OAT access identified by participants included the high cost of transportation, residing or working in remote communities and few local OAT prescribers. A variety of treatment motivations and goals that impacted OAT satisfaction are also highlighted. CONCLUSION: This study demonstrates that patient satisfaction with OAT service access in a rural and coastal setting is multi-factorial and geographic proximity alone does not fully explain OAT accessibility issues in these settings. Accessibility to OAT may be improved through delivery services, expanded OAT prescribing authorisation beyond physician-only regulations, health authorities covering transportation costs and continual assurance that prescribing practices meet individuals' goals. INTRODUCTION: Bien que les régions rurales soient touchées de manière disproportionnée par l'approvisionnement en drogues toxiques, on sait peu de choses sur les facteurs contextuels qui influencent l'accès au traitement par agoniste opioïde (TAO) spécifique aux résidents ruraux. La présente étude examine ces facteurs dans un contexte rural et côtier en Colombie-Britannique, au Canada. MTHODES: Des méthodes qualitatives ont été utilisées pour examiner les obstacles et les facilitateurs de l'accès aux TAO. Entre juillet et octobre 2021, des entretiens semi-structurés ont été menés avec des personnes qui consomment des drogues résidant dans une communauté rurale et côtière. L'analyse thématique a été utilisée pour identifier les thèmes et sous-thèmes émergents. Les résultats ont été corroborés par l'équipe de recherche et un comité consultatif communautaire local. RSULTATS: Vingt-sept (n = 27) participants ont décrit les facteurs limitants et facilitants qui ont influé sur l'accessibilité au TAO. L'accès était moins difficile lorsque la pharmacie du TAO des participants était proche, avait des heures d'ouverture prolongées ou lorsque les pharmacies offraient des services de livraison. Parmi les obstacles à l'accès au TAO mentionnés par les participants, il y avait le coût élevé du transport, le fait de résider ou de travailler dans des collectivités éloignées et la rareté des prescripteurs locaux du TAO. Les participants ont également fait état de divers objectifs et motivations liés au traitement qui ont eu une incidence sur la satisfaction à l'égard du TAO. CONCLUSION: Cette étude démontre que la satisfaction des patients à l'égard de l'accès aux services du TAO en milieu rural et côtier est multifactorielle et que la proximité géographique n'explique pas à elle seule les problèmes d'accessibilité au TAO dans ces milieux. Cette accessibilité peut être améliorée par des services de livraison, l'élargissement de l'autorisation de prescrire un TAO au-delà des règlements réservés aux médecins, la prise en charge des coûts de transport par les autorités sanitaires et l'assurance continue que les pratiques de prescription répondent aux objectifs des individus.

Road to Recovery: protocol for a mixed-methods prospective cohort study evaluating the impact of a new model of substance use care in a Canadian setting.

INTRODUCTION: The Road to Recovery (R2R) Initiative is an innovative model of substance use care that seeks to increase treatment capacity by creating approximately 100 new addiction treatment beds to provide on-demand addiction care in Vancouver, British Columbia, for patients with substance use disorders. The new model also coordinates the region's existing clinical substance use services to support patients across a care continuum that includes traditional office-based addiction treatment and harm reduction services, early withdrawal management and more intensive abstinence-based treatment programming. To understand the impact of offering on-demand and coordinated substance use care, an observational cohort of individuals who access any R2R clinical service will be created to examine health and social outcomes over time. METHODS AND ANALYSIS: This prospective mixed-methods study will invite individuals from Vancouver, Canada, who access substance use treatment through the R2R model of care to (1) complete a baseline and 12-month follow-up quantitative questionnaire that solicits sociodemographic, substance use and previous addiction treatment data and (2) provide consent to the use of participants' personal identifiers to access health records for chart review and for annual linkage to select health and administrative databases to allow for ongoing (virtual) community follow-up over 5 years. Additionally, a purposive sample of cohort participants will be invited to participate in baseline and 12-month follow-up qualitative interviews to share their experiences accessing R2R and identify challenges and opportunities associated with the implementation of R2R. ETHICS AND DISSEMINATION: The study was approved by the University of British Columbia Providence Health Care Research Ethics Board in September 2023. Results from the proposed study will be published in peer-reviewed journals, presented at national and international scientific conferences and disseminated through regular meetings with policymakers, individuals with lived and living experience, and other high-level stakeholders, academic presentations and lay media.

Access to tablet injectable opioid agonist therapy in rural and smaller urban settings in British Columbia, Canada: a qualitative study.

BACKGROUND: Rural and smaller urban settings in Canada are disproportionately impacted by the overdose crisis, highlighting the need for novel public health interventions within these jurisdictions. Tablet injectable opioid agonist therapy (TiOAT) programs have been implemented in select rural communities as a means to address drug-related harms. However, little is known about the accessibility of these novel programs. Therefore, we conducted this study to understand the rural context and factors that affected access of TiOAT programs. METHODS: Between October 2021 to April 2022, individual qualitative semi-structured interviews were conducted with 32 individuals enrolled in a TiOAT program at participating rural and smaller urban sites in British Columbia, Canada. Interview transcripts were coded using NVivo 12 and data were analyzed thematically. RESULTS: TiOAT access varied considerably. TiOAT delivery in rural settings is complicated due to geographic challenges. Participants who were homeless and staying at a nearby shelter or those in centrally-located supportive housing had minimal issues compared to those living in more affordable housing on the outskirts of town with limited transportation options. Dispensing policies that required daily-witnessed ingestion multiple times daily were challenging for most. Only one site provided evening take-home doses whereas participants at the other site could only resort to the illicit opioid supply to address withdrawal outside of program hours. Participants described the clinics as providing a positive and familial social environment compared to experiences of stigma elsewhere. Medication interruptions did occur when participants were in hospital and custodial settings, leading to withdrawal, program discontinuation, and overdose risk. CONCLUSIONS: This study highlights the beneficial ways in which health services tailored for people who use drugs can create a stigma-free environment with an emphasis on social bonds. Other factors such as transportation access, dispensing policies, and access in rural hospitals and custodial settings produced unique challenges for rural people who use drugs. Public health authorities in rural and smaller settings should consider these factors when designing, implementing, and scaling up future substance use services, including TiOAT programs.

Disease-related stigma among people who inject drugs in Toronto amidst the COVID-19 pandemic.

Background: Stigma overwhelmingly affects people who inject drugs. The COVID-19 pandemic posed unique challenges for people who inject drugs, who are already stigmatized as being "dangerous and spreading disease." The present study explored ways in which stigma was experienced by a sample of people who inject drugs in Toronto, Canada following COVID-related public health precaution measures. Methods: Qualitative interviews were conducted with people who inject drugs (n = 24) recruited from supervised consumption sites in Toronto, Canada. The semi-structured interview guide focused on the impact of COVID-19 on participants' health and social well-being. Interviews took place six-months after initial COVID-19 precautions (September-October 2020). We used thematic analysis to examine findings, with stigma being an emergent theme. Results: Participants described heightened acts of stigma after COVID-19 restrictions were implemented, including feeling treated as "diseased" and the cause of COVID-19's spread. They reported being less likely to receive emergency care during events such as overdoses. Participants perceived increased disease-related stigma evident through actions of stigma, including amplified dehumanization by the public, others avoiding all contact with them, and more discrimination by police and hospital systems. Conclusion: Participants provided specific examples of how stigmatizing behaviors harmed them after COVID-19 precautions began. It is plausible that stigma contributed to the dramatic increase in fatal overdoses, difficulty accessing housing, and further difficulty accessing needed healthcare in our setting. Integrating evidence-based harm reduction approaches in areas where stigma is evident might offset harms stemming from disease-related stigma and mitigate these harms during future public health emergencies.

Challenges of implementing safer supply programs in Canada during the COVID-19 pandemic: A qualitative analysis.

BACKGROUND: Canada is experiencing an unprecedented drug toxicity crisis driven by a highly toxic unregulated drug supply contaminated with fentanyl, benzodiazepine, and other drugs. Safer supply pilot programs provide prescribed doses of pharmaceutical alternatives to individuals accessing the unregulated drug supply and have been implemented to prevent overdose and reduce related harms. Given the recent emergence of these pilot programs and the paucity of data on implementation challenges, we sought to document challenges in their initial implementation phase. METHODS: We obtained organizational progress reports from Health Canada, submitted between 2020 and 2022 by 11 pilot programs located in British Columbia, Ontario, and New Brunswick. We analyzed the data using deductive and inductive approaches via thematic analysis. Analyses were informed by the consolidated framework for implementation research. RESULTS: We obtained 45 progress reports from 11 pilot programs. Six centres were based in British Columbia, four in Ontario, and one in New Brunswick. Four overarching themes were identified regarding the challenges faced during the establishment and implementation of pilot programs: i) Organizational features (e.g., physical space constraints, staff shortages); ii) Outer contexts (e.g., limited operational funds and resources, structural inequities to access, public perceptions); iii) Intervention characteristics (e.g., clients' unmet medication needs); and iv) Implementation process (e.g., pandemic-related challenges, overly medicalized and high-barrier safer supply models). CONCLUSIONS: Safer supply pilot programs in Canada face multiple inner and outer implementation challenges. Given the potential role of safer supply programs in addressing the drug toxicity crisis in Canada and the possibility of future scale-up, services should be well-supported during their implementation phases. Refining service provision within safer supply programs based on the feedback and experiences of clients and program administrators is warranted, along with efforts to ensure that appropriate medications are available to meet the clients' needs.

Drug checking use and interest among people who inject drugs in Toronto, Canada.

BACKGROUND: Drug checking services (DCS) provide information on drug composition to inform consumption practices and monitor unregulated drug markets. We sought to identify correlates of recent informal DCS use (e.g., fentanyl test strips) and willingness to use a formal DCS (co-located within a supervised consumption site and employing laboratory-based analyses) in Toronto, Canada prior to its implementation. METHODS: We calculated outcome prevalence based on baseline questionnaire data from a cohort of people who inject drugs in downtown Toronto between November 2018-October 2019 and conducted multivariable Poisson regression analyses. Outcomes included recent (i.e., past six-month) informal DCS use and willingness to use a formal DCS, if implemented. We also conducted a sub-analysis assessing willingness to use a formal DCS following an unexpected drug reaction. RESULTS: Among 604 participants, 12% (n=74) reported recent informal DCS use, 73% (n=442) reported willingness to use a formal DCS, and 88% (n=530) reported willingness to use a formal DCS in response to an unexpected drug reaction. Based on 567 participants with complete data, we found that recent injection at a supervised consumption site or overdose prevention site were both associated with recent informal DCS use (respectively, adjusted prevalence ratio [aPR]=2.44, 95% confidence interval [CI]: 1.11-5.35; aPR=1.78, 95% CI: 1.00-3.15). Recent informal DCS use and recent overdose were both associated with willingness to use a formal DCS (respectively, aPR=1.15, 95% CI: 1.02-1.30; aPR=1.10, 95% CI: 1.00-1.22). CONCLUSION: Although recent informal DCS use was infrequently reported in our study, willingness to use a formal DCS was high. Our findings indicate a potential role for laboratory-based DCS in mitigating overdose risk among individuals accessing the unregulated drug supply. However, barriers that impede service access or reduce interest should be addressed to ensure equitable use among those at heightened risk of overdose.

Perspectives of people in Philadelphia who use fentanyl/heroin adulterated with the animal tranquilizer xylazine; Making a case for xylazine test strips.

Background: Xylazine is an animal tranquilizer increasingly detected in those who have died of an opioid overdose in Philadelphia, PA and elsewhere. Despite an increasing presence of xylazine in the local fentanyl/heroin drug market and its association with ulcers, there are few perspectives about xylazine from people who use drugs and no data about the utility of a hypothetical xylazine test strip. Methods: Between January to May 2021 in Philadelphia, PA, people who used fentanyl/heroin and had previously used fentanyl test strips were queried about xylazine and hypothetical xylazine test strips. Interviews were transcribed and analysis was conducted via conventional content analysis. Results: Participants (7 spontaneously, 6 after probing, n = 13) discussed "tranq" (i.e., xylazine) in the fentanyl/heroin supply. None enjoyed tranq or wanted it in their fentanyl/heroin. Participants suspected xylazine saturation of the fentanyl/heroin market, disliked the sensation of the drug, and had safety concerns about xylazine exposure. Participants did not indicate concerns about overdose. All were interested in hypothetical xylazine test strips. While previous literature indicates that some people enjoy tranq in their fentanyl/heroin, our findings differed, with participants expressing concern about the consequences of undesired exposure. The interest expressed for xylazine test strips by people who use fentanyl/heroin is an important opportunity to center their voices in the development of innovations designed to mitigate the harms of unwanted adulterant exposure. Conclusions: In the present study, people who use fentanyl/heroin indicated an interest to test their drug for the presence of xylazine prior to use.

Investigating a bidirectional relationship between overdose and provision of injection initiation assistance among persons who inject drugs in Vancouver, Canada and Tijuana, Mexico.

BACKGROUND: Individuals who initiate injection drug use often receive assistance from an injection-knowledgeable peer. Persons who assist peers in injection initiation events often inject frequently, which heightens overdose risk. As such, overdose and injection initiation events may be correlated. To explore a potential relationship, we assessed temporal associations between experiencing a non-fatal overdose and assisting others in initiating injection drug use among persons who inject drugs in two North American cities - Vancouver, Canada and Tijuana, Mexico. METHODS: From 2014 to 2018, this retrospective cohort study included people who inject drugs from Vancouver (n=1332) and Tijuana (n=666) who completed a baseline and six-month follow-up interview. Within each site, we assessed bidirectional temporal associations using two separate multivariable logistic regression models: for model 1, recent provision of injection initiation assistance (at six months) was the outcome and recent overdose (at baseline) was the exposure; for model 2, recent overdose (at six months) was the outcome and recent provision of injection initiation assistance (at baseline) was the exposure. Both models adjusted for potential confounders. RESULTS: Vancouver-based participants reporting overdose at baseline had 163% greater odds of reporting provision of injection initiation assistance at follow-up (adjusted Odds Ratio [aOR] 2.63; 95% Confidence Interval [CI] 1.41-4.90); while participants reporting provision of injection initiation assistance at baseline had 89% greater odds of reporting a non-fatal overdose at follow-up (aOR 1.89; 95% CI 1.00-3.57). Among Tijuana-based participants, we did not observe a statistically significant association in either direction. CONCLUSION: Findings in Vancouver suggest that injection initiation assistance and overdose are bidirectionally-associated phenomena. The present findings highlight the need for interventions that ensure that persons who provide injection initiation assistance are given overdose prevention support, both for themselves and for those they assist to initiate injection drug use. While our Tijuana-based results did not suggest a bidirectional relationship, preventative approaches should nonetheless be undertaken.

Expanding access to diacetylmorphine and hydromorphone for people who use opioids in Canada.

The increasing incidence of fatal opioid overdose is a public health crisis in Canada. While buprenorphine/naloxone and methadone are the standard first-line of opioid substitution options, limitations, including difficulty achieving long-term retention for some people who use opioids, are well known. For this group, injectable diacetylmorphine or hydromorphone can achieve positive outcomes, including high retention rates, reduced use of unregulated opioids, and reduced criminal activity. In May 2019, Health Canada announced changes to increase the accessibility of diacetylmorphine and hydromorphone, and in September 2019, the CIHR-funded Canadian Research Initiative in Substance Misuse released a national clinical guideline for diacetylmorphine and hydromorphone as additional frontline substitution options. While these developments present opportunities for scale-up, significant financial, structural, and practice barriers continue to impede access. This commentary explores the current state of policy and practice for diacetylmorphine and hydromorphone as opioid substitution options in Canada, outlines the rationale for rapid expansion of access, and highlights clinical and policy changes that must be undertaken or the death toll will continue to rise.
