Police-related barriers to harm reduction linked to non-fatal overdose amongst sex workers who use drugs: Results of a community-based cohort in Metro Vancouver, Canada

Abstract

BackgroundHigh rates of overdose and overdose-related mortality in North America represent a pressing health and social concern. Women sex workers face severe health and social inequities, which have been linked to structural factors including negative police interactions; however, little is known regarding the burden of overdose or how policing impacts overdose risk amongst sex workers who use drugs. Given this, we aimed to explore the independent effects of experiencing police-related barriers to harm reduction on non-fatal overdose amongst women sex workers who use drugs in Metro Vancouver, Canada over a 7.5-year period. MethodsData were drawn from An Evaluation of Sex Workers Health Access (AESHA), a community-based open prospective cohort of women sex workers in Metro Vancouver, from 2010 to 2017. Using multivariate logistic regression with generalized estimating equations (GEE), we used a confounder modeling approach to identify the independent effect of experiencing police-related barriers to harm reduction strategies on non-fatal overdose amongst sex workers using drugs within the last six months at each study visit. ResultsAmongst 624 participants, 7.7% overdosed within the last six months at baseline and 27.6% overdosed during the study period, contributing 287 non-fatal overdose events over the 7.5-year period. 68.6% reported police-related barriers to harm reduction strategies during the study. In a multivariate confounder model, exposure to police-related barriers to harm reduction strategies [AOR: 2.15, CI: 1.60–2.90] was independently associated with higher odds of non-fatal overdose after adjustment for key confounders. ConclusionsOur findings suggest that in the context of the current overdose crisis, adversarial policing practices may undermine access to lifesaving overdose prevention services and exacerbate overdose risks for marginalized women. Findings underscore the urgent need to scale-up access and remove barriers to progressive harm reduction strategies for women sex workers.
