Pediatric clinic tests if videos can replace doctor repetition

This study tests whether showing short educational videos to families during pediatric cardiology visits helps them understand their child's condition and makes the clinic run more efficiently. About 300 children and their caregivers will participate at one clinic in San Antonio. The videos cover common reasons for visits like chest pain, heart murmurs, or fainting. Researchers will compare visits before and after the videos are introduced to see if they improve knowledge, satisfaction, and reduce time doctors spend repeating explanations.
