Ability to successfully use an epinephrine auto-injector after switching to a different device

Methods We evaluated mothers of food-allergic children participating in a UK study of epinephrine auto-injectors (EAI), 1 year after they were first trained to use an EAI, either Anapen or Epipen (old design). Participants’ ability to deliver epinephrine using their device was assessed using a simulated anaphylaxis scenario. Participants then underwent repeat assessment using a different EAI device, randomly allocated, without training on the new device. The UK-approved EAIs Epipen (new/old designs), JEXT or Anapen were used, or Intelliject, an EAI with audio/visual prompts approved in North America as AuviQ(tm) and Allerject. ISRCTN29175528
