Description

Over 100 overdose prevention sites (OPS) operate in various jurisdictions. This systematic review will identify peer-reviewed studies, reports, and theses that evaluate the cost and benefits of OPS, relying on five electronic databases. The final data analysis will include the range of cumulative benefits, costs, and ratios associated with operating OPS. The authors of this study will be selected by the recommendation of the Vancouver Area Network of Drug Users (VANDU) board of directors. This review has the potential to provide evidence-based knowledge through a community-based research approach on the cost savings of public health interventions implemented through harm reduction philosophy for underserved populations.
