Summary

This study tests whether online educational videos can help children on blood thinners and their families better understand their medication. About 248 participants will watch short videos covering topics like warfarin, INR testing, and safety. Researchers will measure changes in knowledge, stress, and satisfaction to see if this approach works better than traditional teaching.
