Transition From a Paper Diary to an Electronic Diary by Parents of Preschool Children With Food Allergies: Pilot Study

E-diaries may resolve various issues associated with P-diaries and may be useful tools for communication between parents and physicians regarding disease management. Since the number of participants was small (ie, 5) and the study was conducted at a single facility, theoretical saturation was not reached. In the future, it will be necessary to increase the number of participants to validate these findings.
