This randomized controlled trial aims to evaluate the effect of an artificial intelligence-driven mobile application on nurses' knowledge and attitudes toward atraumatic care for hospitalized children. Participants, who are pediatric nurses, will be randomly assigned to either the intervention group, using the mobile application, or the control group receiving standard education. The primary outcomes are improvements in nurses' knowledge and attitudes, measured after the intervention. The study seeks to determine whether the mobile application enhances nurses' competence in providing atraumatic care compared to usual training methods.
