NCT01217138

Brief Summary

Part of the problems related with proper use of epinephrine autoinjector may be related with the design of the autoinjector itself.The aim of the study is to investigate whether minor modifications in the design of currently available epinephrine autoinjector ease its use and abrogate common use errors.

Outcome Measures

Primary Outcomes (1)

  • Rate of participants correctly demonstrating the use of epinephrine autoinjector.

Secondary Outcomes (3)

  • Mean total score participants get during demonstration of epinephrine autoinjector use

  • Mean time required to administer epinephrine autoinjector

  • Unintentional self injection of autoinjector into thumb

Study Arms (2)

Original epinephrine autoinjector group

OTHER

Participants were given original epinephrine autoinjector trainer wrapped by a gray sticky paper.

Device: Epinephrine autoinjector

Modified epinephrine autoinjector group

ACTIVE COMPARATOR

Participants were given the same epinephrine autoinjector trainer wrapped by a gray sticky paper which was modified by changing gray safety cap to red with an atomizer paint and placing a yellow arrow pointing to the black injection tip.

Device: Epinephrine autoinjector

Interventions

We used 2 epinephrine autoinjector trainers and wrapped them by a gray sticky paper. Then,modified one of the trainers by changing gray safety cap to red with an atomizer paint and placing a yellow arrow pointing to the black injection tip.We provided three-step written and visual instruction sheet to use epinephrine autoinjector in Turkish same as given on the original trainer and changed that of the second trainer according to the modifications we made. Scoring system originally devised by Sicherer et al was used. Participants successively doing all steps were accepted to demonstrate autoinjector use correctly. Participants who tackled with black tip of autoinjector in order to eject needle after removing safety cap was regarded as unsuccessful since this may cause unintentional injection of epinephrine. All participants were scored and timed separately.
