Non-Wearable Audiovisual Distraction for Children's Medical Anxiety in the ED

Pediatric emergency department (ED) visits often cause significant anxiety and stress for young patients due to unfamiliar environments and invasive medical procedures. Non-pharmacological interventions, such as distraction, are vital for reducing pediatric anxiety and improving procedural outcomes. This study evaluates the effectiveness of a non-wearable, immersive audiovisual distraction system (LG StanbyME display) in alleviating pediatric anxiety during emergency department care, compared to standard care. The main questions it aims to answer are: Does non-wearable audiovisual distraction reduce anxiety levels in pediatric emergency patients compared to standard care? Does the intervention improve physiological indicators of distress, such as Heart Rate Variability (HRV)? Participants will: Be randomly assigned to either the non-wearable audiovisual distraction group or the routine care group. Undergo continuous physiological monitoring (HRV) and clinical anxiety assessment (mYPAS-SF) during their ED visit.
