Determinants of Cutaneous Injection-Related Infection Care at a Supervised Injecting Facility

PurposeTo evaluate the factors associated with receiving cutaneous injection-related infection (CIRI) care among a representative cohort of supervised injecting facility (SIF) users.MethodsData were collected biannually as part of a prospective cohort, the Scientific Evaluation of Supervised Injection study. Kaplan-Meier methods and Cox proportional hazards regression with recurrent events were used to examine incidence and factors associated with CIRI care, respectively.ResultsOne thousand eighty individuals were recruited between December 1, 2003 and January 31, 2008. The incidence density of participants receiving CIRI care was 22.0 per 100 person-years (95% confidence interval [CI]: 19.6–24.6). In the adjusted Cox proportional hazard model, female sex (adjusted hazard ratio [AHR] = 1.87 [95% CI: 1.32–2.64]), unstable housing (AHR = 1.39 [95% CI: 1.02–1.88]), and daily heroin injection (AHR = 1.52 [95% CI: 1.13–2.04]) were independently associated with receiving CIRI care at the SIF.ConclusionsThese results describe who is more likely to receive CIRI care, which is of use to those engaged with policy and practice of treatment regimens involving this population.
