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

Abstract
Street-involved youth who use drugs (YWUD) face an elevated risk of HIV acquisition and represent a key population for HIV prevention initiatives, including pre-exposure prophylaxis (PrEP). However, little is known regarding the acceptability and feasibility of PrEP uptake and adherence among this multiply-marginalized population. Semi-structured qualitative interviews were conducted with 24 street-involved YWUD (ages 17-24) to examine their perspectives toward PrEP; youth were recruited through a longitudinal prospective cohort study in Vancouver, Canada. Youth reported high levels of ambivalence toward PrEP despite engagement in HIV-related risk behaviors. This ambivalence was driven by misperceptions regarding HIV transmission, including stigmatizing associations between HIV transmission and personal hygiene. Such misperceptions led participants to enact strategies that were ineffective in preventing HIV transmission. Participants contested their inclusion as a "key population" for PrEP, which limited their enthusiasm for PrEP uptake and adherence. Participants also highlighted that wider social-structural inequities (e.g., housing vulnerability, poverty) that produced HIV-related risks were likely to undermine sustained PrEP use. Findings demonstrate the need for tailored implementation strategies to increase PrEP acceptability, including targeted education and anti-stigma interventions to increase awareness about HIV transmission. Interventions should also target structural inequities in order to fully address HIV risk and PrEP ambivalence.

Requiring help injecting among people who inject drugs in Toronto, Canada: Characterising the need to address sociodemographic disparities and substance-use specific patterns. Drug Alcohol Rev 2022; 41:1062-1070. [PMID: 35577755 DOI: 10.1111/dar.13473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Revised: 03/09/2022] [Accepted: 03/26/2022] [Indexed: 12/01/2022]
Abstract
INTRODUCTION Those requiring help injecting are at an elevated risk of injection-related injury and blood-borne infections and are thus a priority group for harm reduction programs. As supervised consumption services (SCS) are scaled-up across Canada, information on those who require help injecting is necessary to inform equitable service uptake. We characterised the sociodemographic, structural and drug use correlates of needing help injecting among a cohort of people who inject drugs in Toronto, Canada. METHODS A cross-sectional baseline survey was administered between November 2018 and March 2020. Unadjusted and multivariable logistic regression models examined associations with requiring help injecting in the past 6 months. A gender-stratified sub-analysis described characteristics of receiving help among those requiring it. RESULTS Of 701 participants (31.0% cisgender women), 294 (41.9%) needed recent help injecting. In unadjusted analyses, being a racialised, non-Indigenous person (odds ratio [OR] 1.79, 95% confidence interval [CI] 1.13-2.86) or a cisgender woman (OR 1.72, 95% CI 1.24-2.39) were associated with needing help. In multivariable analyses, requiring assistance was associated with needing frequent help preparing drugs (adjusted OR [AOR] 9.52, 95% CI 4.78-21.28), fewer years since first injection (AOR for 1 year increase: 0.97, 95% CI 0.95-0.99) and injecting stimulants. Among those who required help, cisgender women reported needing assistance more often than cisgender men (P = 0.009). DISCUSSION AND CONCLUSIONS Over two-fifths of the sample required help injecting; requiring assistance was associated with sociodemographic indicators and substance use-specific patterns. Findings highlight the need to scale-up educational resources for those who receive or provide help injecting, as well as SCS that accommodate onsite injection assistance.

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

Factors associated with injury and blood-borne infection risk when providing assisted injection among people who inject drugs. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 97:103297. [PMID: 34077825 PMCID: PMC9844096 DOI: 10.1016/j.drugpo.2021.103297] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Revised: 04/22/2021] [Accepted: 05/05/2021] [Indexed: 01/19/2023]
Abstract
OBJECTIVE Prior research has associated assisted injection with risk behaviors, but other risks such as injury, missed veins, and incidental exposures to blood-borne infections during an injection episode have not been assessed. In the following, we present the frequency of these other risks and determine factors associated with missing a vein and incidental blood exposure among people who inject drugs (PWID). METHODS We conducted a cross-sectional analysis of data from PWID who were recruited using targeted sampling in Los Angeles and San Francisco, California, during 2016 and 2017. The analytic sample consist of 336 participants who reported providing injection assistance in the last 6 months. Multivariate logistic regression models were developed for reporting the following risks: missing a vein; getting the recipient's blood on the injection provider; and getting blood on clothes or surfaces. RESULTS In the last 6 months, the most common negative consequences were getting blood on clothes or surfaces (40%), getting the recipient's blood on the injection provider (23%), and missing a vein (17%). In multivariate logistic regression analysis, missing the vein was significantly associated with higher odds of assisting a leg injection while getting the injection recipient's blood on the provider or getting blood on clothes or nearby surfaces was associated with higher odds of assisting a groin injection injecting in the groin. CONCLUSION Providing injection assistance can result in incidental blood exposures and injury, particularly when injecting in sensitive locations on the body. Harm reduction interventions to reduce risks associated with this practice are essential to improving the well-being of PWID.

Abstract
BACKGROUND Assisted injection is a high-risk and common practice among people who inject drugs (PWID) and occurs for diverse reasons according to qualitative research. To develop interventions for reducing assisted injection risks, it is important to understand the practices of PWID who provide injection assistance, including their motivations for providing assistance. METHODS Using follow-up data from an efficacy trial among PWID recruited in Los Angeles and San Francisco, CA (n=601), we present descriptive statistics on motivations for providing injection assistance and use multivariable logistic regression modelling to examine factors associated with these motivations. RESULTS PWID provided injection assistance most commonly to friends and acquaintances. A quarter provided assistance on a daily basis. The most common motivations for providing assistance were skill and injury prevention. PWID also provided assistance to stop pestering and for compensation in money or drugs. In separate models examining factors associated with the five main motivations, we found injury prevention to be associated with skill injecting others, neck injection, methamphetamine use, and recycling income. Pestering was associated with injury prevention, neck and hand injection, speedball use, and syringe selling. Skill was associated with injury prevention, neck and hand injection, being physically assaulted, and age. Providing assistance for money was associated with providing assistance for food or drugs, armpit injections, being female, and providing assistance more frequently. Providing assistance for drugs was associated with compensation in food or money, goofball injection, selling drugs, and panhandling. CONCLUSION Providing injection assistance is associated with injection needs of recipients and drug scene participation. We urgently need new interventions for reducing assisted injection risks. Since injection providers report being motivated by skill and to prevent injury, interventions such as training in safer injection techniques are likely to be met with enthusiasm.

Assisted injection within supervised injection services: Uptake and client characteristics among people who require help injecting in a Canadian setting. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 86:102967. [PMID: 33039705 PMCID: PMC8026755 DOI: 10.1016/j.drugpo.2020.102967] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 09/18/2020] [Accepted: 09/24/2020] [Indexed: 01/24/2023]
Abstract
BACKGROUND People who require help injecting illicit drugs experience elevated rates of a range of health-related harms, including overdose and acquisition of blood-borne pathogens. In response, some supervised injection services (SIS) in Canada have begun to permit clients to be physically injected by fellow clients or staff members. However, little is known about uptake and characteristics of clients who engage in this practice. We therefore sought to examine factors associated with receiving injection assistance at SIS among people who require help injecting drugs in Vancouver, Canada. METHODS Data were drawn from two community-recruited prospective cohort studies of people who inject drugs (PWID). We used multivariable generalized estimating equation (GEE) analyses with time-updated covariates to identify factors associated with self-reported receipt of injection assistance at SIS. RESULTS Between June 2017 and December 2018, 319 individuals who reported having recently required help injecting were included in the study. Of these, 160 (51.0%) were women and the median age was 42 years at baseline. In total, 54 (16.9%) participants reported receiving injection assistance at a SIS at least once over an average of 3.3 months of follow-up. In multivariable GEE analyses, recent homelessness (Adjusted Odds Ratio [AOR] = 2.04; 95% confidence interval [CI]: 1.13 - 3.66), fentanyl injection (AOR = 3.45; 95% CI: 1.42 - 8.41), non-fatal overdose (AOR = 1.86; 95% CI: 1.02 - 3.38) and enrolment in methadone maintenance therapy (AOR = 1.89; 95% CI: 1.03 - 3.47) were associated with increased odds of receiving injection assistance at SIS. CONCLUSION Although uptake of assisted injection at SIS was relatively low among this sample of people who require help injecting, this practice was associated with several indicators of structural vulnerability and drug-related risk. These findings suggest that accommodating assisted injection within SIS may be providing opportunities to engage and reduce harms among higher-risk subpopulations of PWID in this setting.

Abstract
BACKGROUND Drug-related overdoses were declared a public health emergency in British Columbia, Canada in April, 2016 facilitating the scale-up of responses including rapid sanctioning and implementation of overdose prevention sites (OPSs). OPSs are a health service providing supervised injection and immediate overdose response. In BC, OPSs were operational within weeks of sanctioning. In the first year of operation over 20 OPSs were established with approximately 550,000 visits and no overdose deaths at any site. In this paper, we examine the implementation of OPSs as a novel and nimble response to prevent overdose deaths as a result of injection drug use. METHODS A multiple case study design was used with the Consolidated Framework for Implementation (CFIR) informing the analysis. Three sites in a single city were included with each site constituting a case. In this paper, we focus on qualitative interviews with 15 staff and their perceptions of the implementation of the OPSs as well as provincial and local documents. RESULTS The legislative process to implement OPSs was unprecedented as it sanctioned supervised injection services as an extraordinary measure under a declared public health emergency. Innovative and inclusionary practices were possible within state-sanctioned OPSs, as the sites were government-directed yet community-developed, with PWUD centred in service design, implementation and delivery. OPSs lack permanency and may be limited to the duration of the public health emergency. CONCLUSION The rapid implementation of OPSs provides an international example of an alternative to lengthy and often onerous sanctioning processes for supervised consumption services (SCSs). Overdose prevention sites provide an example of a novel service design and nimble implementation process that combines the benefits of state-sanctioned injection services with community-driven implementation. Such evidence questions the continued acceptability of governments' restrictive sanctioning processes, which have limited expansion of SCSs internationally and the implementation of services that are not necessarily aligned with the needs of PWUD.

Abstract
BACKGROUND Peer-to-peer injection (either providing or receiving an injection to/from a person who injects drugs [PWID]) is common (19%-50%) among PWID. Most studies of peer-to-peer injection have focused on receiving injection assistance, with fewer examining providing injection assistance and none considering characteristics of PWID who do both. We examined characteristics of PWID by peer-to-peer injection categories (receiving, providing, both, and neither) and determined if these behaviors were associated with receptive and distributive syringe sharing. METHODS Los Angeles and San Francisco PWID (N = 777) were recruited using targeted sampling methods and interviewed during 2011-2013. Multinomial logistic regression was used to determine characteristics associated with peer-to-peer injection categories and logistic regression was used to examine if peer-to-peer categories were independently associated with distributive and receptive syringe sharing. RESULTS Recent peer-to-peer injection was reported by 42% of PWID (18% provider; 14% recipient; 10% both). In multinomial regression analysis, PWID reporting any peer-to-peer injection were more likely to inject with others than those who did neither. Injection providers and those who did both were associated with more frequent injection, illegal income source, and methamphetamine injection while injection recipients were associated with fewer years of injection. Injection providers were younger, had more years of injecting, and were more likely to inject heroin than PWID who did neither. In multivariate analyses, we found that providers and PWID who did both were significantly more likely to report receptive and distributive syringe sharing than PWID who did neither. CONCLUSION Peer-to-peer injection is associated with HIV/HCV risk. Current prevention strategies may not sufficiently address these behaviors. Modification of existing interventions and development of new interventions to better respond to peer-to-peer injection is urgently needed.

Abstract
BACKGROUND and Aims Injecting illicit drugs in public settings has been linked to a higher risk of a range of drug-related harms, including overdose and HIV infection. However, the factors associated with public injecting among HIV-positive individuals have not been previously explored. We investigated the links between public drug injecting, drug-related harm, and HIV treatment measures among a cohort of HIV-positive persons who inject drugs (PWID) in a Canadian setting. METHODS We used data from a prospective cohort of HIV-positive PWID recruited from community settings in Vancouver, Canada, linked to comprehensive clinical monitoring data in the context of an ongoing Treatment-as-Prevention (TasP) initiative to examine harms associated with public injecting. We used generalized linear mixed-effects analyses to identify longitudinal factors associated with self-reported public drug injection. RESULTS Between 2005 and 2014, 626 HIV-seropositive PWID were recruited, of whom 213 (34%) reported public injection in the preceding 180days. In a longitudinal multivariable model, public injection was positively associated with daily heroin injection (Adjusted Odds Ratio [AOR]=2.63), incarceration (AOR=1.78), and detectable plasma HIV-1 RNA viral load (VL, AOR=1.42). CONCLUSIONS Public injecting was linked to numerous drug-related harms among HIV-seropositive PWID in this setting. Given its link with detectable VL, an important marker of poor HIV treatment outcomes, our findings support prioritizing individuals engaged in public injecting with harm reduction strategies as well as clinical and social supports as a part of TasP-based efforts to prevent HIV-related morbidity and mortality, and HIV transmission.

Abstract
Introduction People who inject drugs (PWID) are highly exposed to drug-dealing networks. In Colombia, a recent dramatic increase in drug consumption has been reported. However, involvement of PWID in drug dealing, their demographics, and drug using behaviors has not been studied. Methods A cross-sectional study involving 1,099 PWID recruited by Respondent Driven-Sampling in five Colombian cities was conducted in 2014. Correlates of demographic characteristics, drug dealing, and injection behaviors were examined by multivariate analysis, and a binary logistic regression model. Results Drug-dealing PWID were predominantly male (86%) with a mean age of 26 years. 56% of participants-of whom 64% had low familial socioeconomic status-had been involved in drug dealing in the previous six months. Compared to non-drug-dealing PWID, drug-dealing PWID reported higher daily injection rate (AOR: 1.3), higher odds of injection equipment confiscation by the police (AOR: 1.4), and were less likely to pay for the drugs they injected (AOR: 0.6). Conclusions Involvement of Colombian PWID in drug dealing was higher than previously reported, and drug-dealing PWID presented sociodemographic vulnerabilities and risky injection practices. Addressing these findings may lead to effective policy design and implementation, decreased drug-dealing involvement, harm reduction, and consumption prevention.

Abstract
We examined the relationship between duration of injecting career and HIV seroconversion among people who inject drugs (PWID) in Vancouver, Canada. Data were derived from HIV-negative PWID enrolled in a prospective cohort study. We employed Kaplan-Meier methods and Cox regression to investigate the effect of length of time since injection drug use initiation on time to HIV seroconversion. In multivariable Cox analysis, duration of injecting career was negatively associated with time to HIV seroconversion (adjusted hazard ratio=0.82; 95% confidence interval [CI]: 0.69-0.97). Our findings highlight the need for interventions that target individuals who participate in high-risk drug use behaviors.
