The Impact of Animated Explanations on Patient Understanding and Decision-making for Percutaneous Coronary Interventions: A Randomized Controlled Trial

This randomized controlled trial investigated whether an internally validated animated video, added to standard consent, improves patient understanding and satisfaction before elective percutaneous coronary intervention. Adults scheduled for percutaneous coronary intervention were randomized to receive either standard consent or standard consent plus an internally validated, local language animated video. Patient understanding and satisfaction were assessed using validated questionnaires and a visual analog scale, respectively. The intervention group demonstrated significantly higher knowledge scores and satisfaction, with no significant influence from socio-economic or educational status. This study supports implementing animated videos to enhance patient comprehension, satisfaction, and bridging the health care gap.
