Impact of Educational Videos on Patient Understanding of Interventional Radiology Procedures

Abstract

Under-awareness of Interventional Radiology (IR) care by the public has been reported. The aim of this study is to evaluate the impact of educational videos to facilitate better patient understanding during the informed consent process. Educational videos for six common IR procedures including chemoembolization, radioembolization, ablation, tunneled central venous catheter placement, port placement, and port removal were developed for educating patients in the pre-procedural setting. One hundred and eighty patients referred to a tertiary academic institution were randomly selected to participate, including 30 patients per procedure type. Anonymous seven question, five-point Likert-scale assessments were administered to the participants before and after engaging with the videos. The survey evaluated patients' perceived understanding of IR procedures and satisfaction with the videos as educational tools. One hundred and eighty patients completed the survey. Comparing post-video to pre-video ratings, there was an increase in patients' understanding of the involved anatomy (4.5 vs 3.3; p<0.01), understanding of procedure benefits (4.6 vs 3.7; p<0.01), understanding of procedural risks (4.5 vs 3.3; p<0.01), understanding of procedural alternatives (3.4 vs 2.7; p<0.01), and overall procedural understanding (4.7 vs 3.4; p<0.01). Additionally, patients had a positive impression of the videos with a mean overall satisfaction rating of the video-assisted explanation of 4.80. A patient-centric video-assisted informed consent for IR procedures enhances patients' understanding and results in high patient satisfaction.
