PULSE - Patient Understanding and Learning Through Structured Education - Effectiveness and Implementation of Patient Education Videos in a New Pediatric Cardiology Clinic: A Stepped Wedge Cluster Randomized Trial

This study is looking at whether short educational videos shown during pediatric cardiology visits can help families better understand their child's condition while also making clinic visits run more efficiently. Families coming to a pediatric cardiology clinic may watch short videos related to why they are there (for example: chest pain, heart murmurs, fainting, sports clearance, or Kawasaki disease). The videos are meant to explain common heart-related conditions and answer questions before the doctor comes into the room.

Researchers want to see if this:

* helps parents and patients learn more, * improves satisfaction with the visit, * helps families feel more involved in decisions, * and reduces the amount of time doctors spend repeating the same explanations.

How the study works:

One clinic site in San Antonio, TX will start using the videos at different times. Researchers will compare clinic visits before and after the videos are introduced.

Who is included:

Children being seen in pediatric cardiology clinics and their caregivers. Pregnant women referred for fetal heart evaluations may also be included.

What information is collected:

Clinic timing information (such as wait times and doctor visit length), Satisfaction surveys, Optional knowledge questionnaires, Basic medical record information needed for the study.

Risk level: The study is considered "minimal risk." Patients are still getting normal medical care. No drugs, devices, or experimental treatments are being tested.

Privacy protections: Data will be stored on secure hospital systems. Researchers plan to remove identifying information when analyzing results. Medical record numbers are only temporarily used to connect survey data with clinic data.

Why the study matters:

The clinic hopes the videos can make visits less stressful, improve understanding for families, and help doctors spend more time on personalized care instead of repeating the same explanations over and over. It may also help clinics work more efficiently and reduce delays.
