A cost-benefit and cost-effectiveness analysis of Vancouver's supervised injection facility

1 February 2008

The following study is an examination of the costs and benefits and cost-effectiveness of Vancouver’s Supervised Injection Site (SIS).

After a review of existing literature regarding both the efficacy of supervised injection sites generally, and Vancouver’s site more specifically, the authors engaged in two kinds of analysis to determine benefit to cost ratios for the Vancouver SIS, and cost effectiveness: linear trend analysis and mathematical modelling. The authors gave particular attention to Insite’s ability to impact HIV infections and overdose deaths, as they were able to obtain reliable temporal and spatial data for each of these two variables.
