Background: Supervised consumption service (SCS) use among people who inject drugs may reduce acute care utilization; however, prior studies have been limited by self-reported outcomes and dichotomous exposures.
Methods: We conducted a prospective cohort study using linked questionnaire and health administrative data among people who inject drugs in Toronto, Canada (2018-2020). Baseline SCS use frequency was defined by a participant's self-reported proportion of injections performed at an SCS over the past six months: "all/most" (≥75 %), "some" (26-74 %), "few" (1-25 %), or "none" (0 %).
Objectives: Health administrative data can be used to improve the health of people who inject drugs by informing public health surveillance and program planning, monitoring, and evaluation. However, methodological gaps in the use of these data persist due to challenges in accurately identifying injection drug use (IDU) at the population level. In this study, we validated case-ascertainment algorithms for identifying people who inject drugs using health administrative data in Ontario, Canada.

The aim of this study was to evaluate the provision of rapid, low-barrier point-of-care (POC) HCV RNA testing and linkage to care among clients of a supervised consumption service (SCS) located within a community health centre in Toronto, Canada. Secondary aims included measuring HCV RNA prevalence at baseline, HCV incidence during follow-up and exploring factors associated with HCV RNA positivity and treatment uptake.

We estimate correlates of HCV care cascade engagement (testing, diagnosis, and treatment) among people who inject drugs in Toronto, Canada and examine the effect of accessing differing supervised consumption service (SCS) models on self-reported HCV testing and treatment. This is a cross-sectional baseline analysis of 701 people who inject drugs surveyed in the Toronto, Ontario integrated Supervised Injection Services (OiSIS-Toronto) study between November 2018 and March 2020.
