Carrying rates of epinephrine devices in children with food-induced anaphylaxis

Background: Carrying epinephrine can save lives in patients with anaphylaxis. The feature of epinephrine in prefilled syringe that commonly prescribed in Thailand may influence the willingness to carry. However, the rates of carrying prefilled syringe epinephrine are unknown in children with history of food-induced anaphylaxis. Objective: To determine the rate of epinephrine carrying in children with history of food-induced anaphylaxis and factors influencing the decision to use the devices. Methods: A cross-sectional study was conducted by performing the structured interview in the parent(s) who were the main caregiver of the children with history of food-induced anaphylaxis. Results: The parents of 99 children (male, 50.5%) were interviewed. The median age of the child was 11 years old (range, 9 months to 18 years). Rate of carrying epinephrine was 84.7% (always 57.6%, some occasions 27.2%). The most common reason for not carrying was the thoughts that the children could avoid the food allergens. The first-aid facility at school was available in 48.3%. Rate of carrying epinephrine tended to be lesser in children attend the schools without first aid facility (p = 0.053). Forty-one patients had relapsing episodes, 34 (82.9%) had epinephrine carried, and 20 (58.8%) injected the epinephrine. The most common reason for not using epinephrine despite carrying was that they were afraid of getting injection (28.5%). Conclusion: Most children with history of food-induced anaphylaxis carried epinephrine, but only half used it at the episodes. Interventions to promote epinephrine-carrying and injection training are needed in our setting.
