Abstract
Cutaneous injection-related infections (CIRI), such as abscesses and cellulitis, are the cause of a substantial burden of morbidity and mortality among injection drug users (IDU). The possible contribution of exposure to correctional environments to CIRI risk has not been fully investigated. Thus, we sought to test the possible relationship between incarceration and CIRI using data from a community-based sample of IDU. Data for these analyses was from the Scientific Evaluation of Supervised Injecting (SEOSI) cohort, linked with administrative records of a local ED in Vancouver, Canada. Using longitudinal analysis we assessed the relationship between the number of ED visits for CIRI care and recent incarceration in a multivariate model including information on possible confounders. Between June 2004 and December 2006, 901 individuals were eligible for our analysis. Of these, 214 (9.6%) visited the ED for CIRI care at least once during the study period. The incidence of ED care for CIRI was 72.9 per 100 person years. In a multivariate model, recent incarceration was associated with a greater number of ED visits for CIRI care (adjusted relative rate = 1.56, 95% confidence interval: 1.31–1.85, P < 0.001). The need for ED treatment for CIRI was common among a sample of local IDU. Exposure to correctional environments was an independent risk factor for visiting the ED for CIRI care, suggesting improvements in infection control in local prisons is urgently needed.
