C-CARE: comparing two years of anaphylaxis in children treated at the Montreal Children’s Hospital

Background Studies suggest that rates of anaphylaxis, the most severe form of an allergic reaction, are increasing in Pediatric Emergency Departments (PED). Significant gaps still exist regarding the prevalence, triggers and temporal trends of anaphylaxis in Canada. The Cross-Canada Anaphylaxis Registry (C-CARE) was created with the primary goal of determining the societal burden of anaphylaxis in Canada; our aim was to use C-CARE to examine temporal trends in anaphylaxis rates.
