Consistent evidence demonstrates that SCFs mitigate overdose-related harms and unsafe drug use behaviours, as well as facilitate uptake of addiction treatment and other health services among people who use drugs (PWUD). Further, SCFs have been associated with improvements in public order without increasing drug-related crime. SCFs have also been shown to be cost-effective. This systematic review suggests that SCFs are effectively meeting their primary public health and order objectives and therefore supports their role within a continuum of services for PWUD. Additional studies are needed to better understand the potential long-term health impacts of SCFs and how innovations in SCF programming may help to optimize the effectiveness of this intervention.

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 hours 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

Canada has long contended with harms arising from injection drug use. In response to epidemics of HIV infection and overdose in Vancouver in the mid-1990s, a range of actors advocated for the creation of supervised injection facilities (SIFs), and after several unsanctioned SIFs operated briefly and closed, Canada’s first sanctioned SIF opened in 2003. However, while a large body of evidence highlights the successes of this SIF in reducing the health and social harms associated with injection drug use, extraordinary efforts were needed to preserve it, and continued activism by local people who inject drugs (PWID) and healthcare providers was needed to promote further innovation and address gaps in SIF service delivery. A growing acceptance of SIFs and increasing concern about overdose have since prompted a rapid escalation in efforts to establish SIFs in cities across Canada. While much progress has been made in that regard, there is a pressing need to create a more enabling environment for SIFs through amendment of federal legislation. Further innovation in SIF programming should also be encouraged through the creation of SIFs that accommodate assisted injecting, the inhalation of drugs. As well, peer-run, mobile, and hospital-based SIFs also constitute next steps needed to optimize the impact of this form of harm reduction intervention.
