Randomized Controlled Trial Comparative StudyEffect of epinephrine autoinjector design on unintentional injection injury.
Epinephrine is an essential medication for the treatment of anaphylaxis. Factors associated with autoinjector design may have a role in its correct use. We compared a new and old epinephrine autoinjector with respect to correct autoinjector use. ⋯ Significantly fewer participants had unintentional injections in the new compared with the old epinephrine autoinjector group (p < 0.001). When all assessment steps are considered, only the rate of placing a wrong tip into the outer thigh was significantly lower in the new compared with the old epinephrine autoinjector group (p < 0.05). The new epinephrine autoinjector is more effective in unintentional injection injuries than the old one; however, it still does not fulfill the criteria of an ideal epinephrine autoinjector.
