(Re)situating expertise in community-based overdose response: Insights from an ethnographic study of overdose prevention sites (OPS) in Vancouver, Canada.

Overdose Prevention Sites (OPS) are low-barrier services where people may use illicit drugs under the monitoring of staff trained to provide life-saving care in the event of an overdose. In British Columbia (BC), Canada, OPS have been rapidly scaled-up as a community-based response to the overdose crisis and are staffed primarily by community members who are also people who use drugs (PWUD). While it is known that PWUD perform vital roles in OPS and other community-based overdose interventions, the expertise and expert knowledge of PWUD in this work remains under-theorised. This study draws on 20 months of ethnographic fieldwork in Vancouver, BC (July 2018 to March 2020), to explore how OPS responders who are PWUD developed and enacted expertise in overdose response. Ethnographic fieldwork focused on four OPS located in Vancouver's Downtown Eastside (DTES) and Downtown South neighbourhoods. Methods included 100 hours of observation in the sites and surrounding areas, three site-specific focus groups with OPS responders (n=20), and semi-structured interviews with OPS responders (n=14) and service users (n=23). Data was analysed with the aim of characterizing the knowledge underpinning responders' expertise, and the arrangements which allow for the formation and enactment of expertise. We found that OPS responders' expertise was grounded in experiential knowledge acquired through their positionality as PWUD and members of a broader community of activists engaged in mutual aid. Responders became skilled in overdose response through frequent practice and drew on their experiential and embodied knowledge of overdose to provide care that was both technically proficient and responsive to the broader needs of PWUD (e.g. protection from criminalization and stigmatizing treatment). Responders emphasized that the spatial arrangements of OPS supported the development of expertise by facilitating more specialized and comprehensive overdose care. OPS became sites of collective expertise around overdose management as responder teams developed shared understandings of overdose management, including processes for managing uncertainty, delegating team responsibilities, and sharing decision-making. This research re-situates theoretical understandings of expertise in community-based overdose response with implications for overdose prevention interventions. Findings underscore the experiential and embodied expertise of PWUD as community-based responders; the importance of supportive environments and team-based approaches for overdose response; and the benefits of community-driven training that extends beyond technical skills of overdose identification and naloxone administration.

"We just don't have the space for it": Geographies of survival and spatial triage in overdose prevention sites.

This study explores the role of Overdose Prevention Sites (OPS) within the geographies of survival of vulnerably housed people who use drugs (PWUD) in Vancouver, British Columbia (BC), Canada. In BC, OPS are low-barrier spaces where people may use drugs under monitoring of trained staff. OPS have been established by people who use drugs, activists, and allied organizations as an emergency measure to prevent overdose deaths. However, OPS have other important uses for PWUD who are vulnerably housed and rely on public spaces for survival. Drawing on two years (2018-2020) of ethnographic fieldwork and interviews with fifty-five people who work at and/or use OPS, we explore how OPS operators negotiated multiple and at times competing uses of service space for everyday survival. Data analysis was guided by critical urban theory to explore the place of OPS within PWUD's geographies of survival, with attention to how different uses of space were negotiated within the context of an illicit drug poisoning crisis and urban control practices that displace and exclude unhoused and vulnerably housed PWUD from the city. We find that OPS accommodated other important potential uses of space for unhoused and vulnerably housed PWUD who relied on public space for survival and were routinely displaced by revanchist urban control strategies. Low-barrier approaches and facility enhancements to OPS improved program accessibility and enabled PWUD to use the sites more broadly to meet survival needs including for mutual-aid, sheltering, and income-generation. However, these secondary uses of OPS presented multiple operational challenges as service volumes increased. We observed processes of 'spatial triage' emerge within sites to manage these challenges, which we characterise as a pragmatic set of rules, procedures, and spatial practices that constrained broader uses of OPS within PWUD's geographies of survival. While spatial triage offered a pragmatic way of prioritizing service delivery to address the most acute survival threats of overdose fatality, these practices had unintended and inequitable impacts on service access. Our findings indicate the need for complementary structural changes as part of overdose responses to reduce the need for spatial triage (i.e., safe, affordable housing and drug decriminalisation) and service innovations to mitigate potential harms (e.g., Expanded drop-in and chill spaces, temporary storage spaces for service user).

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

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

Peer worker involvement in low-threshold supervised consumption facilities in the context of an overdose epidemic in Vancouver, Canada.

Overdose prevention sites (OPS) are a form of supervised consumption facility that have been implemented in Vancouver, Canada as an innovative response to an ongoing overdose epidemic. OPS are primarily staffed by peers - people who use(d) drugs (PWUD) - trained in overdose response. We sought to characterize peer worker involvement in OPS programming, including how this shapes service dynamics and health outcomes among PWUD. Data were drawn from a rapid ethnographic study examining the implementation, operations and impacts of OPS in Vancouver from December 2016 to April 2017. We conducted approximately 185 h of observational fieldwork at OPS and 72 in-depth qualitative interviews with PWUD. Data were analyzed thematically, with a focus on peer worker involvement at OPS and related outcomes. OPS implementation and operations depended on peer worker involvement and thus allowed for recognition of capacities developed through roles that peers were already undertaking through local programming for PWUD. Peer involvement at OPS enhanced feelings of comfort and facilitated engagement with OPS among PWUD. These dynamics and appreciation of peer worker expertise enabled communication with staff in ways that fostered harm reduction practices and promoted health benefits. However, many peer workers received minimal financial compensation and experienced considerable grief due to the emotional toll of the epidemic and lack of supports, which contributed to staff burnout. Our findings illustrate the specific contributions of task shifting OPS service delivery to peer workers, including how this can enhance service engagement and promote the reduction of harms among PWUD. Amidst an ongoing overdose epidemic, expanding formalized peer worker involvement in supervised consumption programming may help to mitigate overdose-related harms, particularly in settings where peers are actively involved in existing programming. However, efforts are needed to ensure that peer workers receive adequate financial support and workplace benefits to promote the sustainability of this approach.

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

North America's overdose epidemic is increasingly driven by fentanyl and fentanyl-adulterated drugs. Supervised consumption sites, including low-threshold models (termed overdose prevention sites; OPS), are now being debated in the United States and implemented in Canada. Despite evidence that gendered and racialized violence shape access to harm reduction among women who use drugs (WWUD), this has not been examined in relation to OPS and amid the overdose epidemic. This study explores how overlapping epidemics of overdose and gendered and racialized violence in Vancouver's Downtown Eastside, one of North America's overdose epicenters, impacts how marginalized WWUD experience OPS. Qualitative analysis using rapid ethnographic fieldwork. Data collection included 185 hours of naturalistic observation and in-depth interviews; data were analyzed thematically using NVivo. Vancouver, Canada. Thirty-five WWUD recruited from three OPS. Participants' experiences of OPS and the public health emergency. The rapid onset and severity of intoxication associated with the use of fentanyl-adulterated drugs in less regulated drug use settings not only amplified WWUD's vulnerability to overdose death but also violence. Participants characterized OPS as safer spaces to consume drugs in contrast to less regulated settings, and accommodation of assisted injections and injecting partnerships was critical to increasing OPS access among WWUD. Peer-administered injections disrupted gendered power relations to allow women increased control over their drug use; however, participants indicated that OPS were also gendered and racialized spaces that jeopardized some women's access. Although women who use drugs in Vancouver, Canada appear to feel that overdose prevention sites address forms of everyday violence made worse by the overdose epidemic, these sites remain 'masculine spaces' that can jeopardize women's access.
