Study finds federal needle exchange programs reduce health care costs and blood-borne infections

The World Health Organization has set a target of reducing hepatitis C infections to fewer than two per 100 people who inject drugs per year as part of an elimination strategy for hepatitis C. In 2024, Canada unveiled its 2024–2030 Sexually Transmitted and Blood-Borne Infection Action Plan that emphasized support for harm reduction programs and expanding the PNEP.

Researchers from Canada and Australia sought to assess the return on investment for Canada’s PNEP, and the potential impact of scaling it up, as part of efforts to eliminate blood-borne infections in prisons.

Using a modeling study, they found that expanding the program to 50% of people in all federal prisons who inject drugs from 2025 to 2030 would prevent 15% of new hepatitis C cases and 8% of injection-related infections compared with the status quo. The work has been published in the Canadian Medical Association Journal.

“Needle exchange programs are evidence-based strategies that prevent transmission of blood-borne viruses, reduce injection-related infections, improve access to medical care, and facilitate entry into substance dependence programs for people who inject drugs,” writes Dr. Farah Houdroge, Disease Elimination Program, Burnet Institute, Melbourne, Australia, with co-authors.

“This study adds to the growing body of evidence supporting PNEPs as effective harm reduction strategies that are also cost saving. Given that they show both health and economic benefits, PNEPs should be a priority not just in Canada, but globally,” the authors say.

In a related commentary, authors argue that more comprehensive interventions to make substance use in correctional institutions safer, and specifically reduce related risks of acute death, are needed.

“Prison-based programs aimed at mitigating the health harms of substance use by correctional inmate populations should be carefully evaluated as part of their implementation, as has been done in the related research with specific respect to needle exchange programs. Without systematic expansion of and increased access to such programs, prisoners in Canada will remain at unnecessarily high risk of ill health and death from the adverse consequences of substance use,” the authors conclude.
