Responding to an explosive HIV epidemic driven by frequent cocaine injection: Is there a role for safe injecting facilities?

Although there have been repeated calls for the establishment of safe injection facilities (SIFs) in Vancouver since the early 1990s, questions remain concerning the feasibility of SIFs due to the high prevalence of injection cocaine and the concomitant problems cocaine use presents. Therefore, we determined the prevalence of willingness to attend SIFs among cocaine injectors in Vancouver and explored the factors associated with this willingness, using data from the Vancouver Injection Drug Users Study. After considering the results derived from this analysis, additional qualitative methods were employed to explore further willingness to use SIFs, barriers and facilitators of SIF utilization, and methods of maximizing use among selected subpopulations of cocaine injectors. The results suggest that a high proportion of cocaine injectors, including some of those most at risk, would attend an SIF if one were available. However in order to better accommodate cocaine injectors, several modifications could be made to conventional SIF service design and delivery. The vast majority of these modifications relate to ensuring effective responses to cocaine toxicity. Given the acceptability of SIFs among cocaine injectors, it appears that an SIF pilot could result in significant and immediate benefits in terms of public health and community safety.
