Impact of YouTube platform in the Realm of Interventional Cardiology Techniques Such as: Double Kissing Crush

Internet has become a widely used resource for obtaining medical information. However, the quality of information on online platforms is still debated. Our goal is to evaluate YouTube video platform regarding its‟ usefulness and reliability in terms of teaching the steps of Double kissing crush (DK-crush) technique. “DK-crush”, “DK-crush stenting technique”, “DK-crush technique” were the key words queried on the search bar of http://www.YouTube.com. All the videos were screened and those videos in English and Turkish and those videos without voice yet involves the explanation of DK-Crush technique were included. Each video was scored according to the reference article in which the steps of the technique were explained in detail. According to the steps in the reference article, the videos were scored. One point was given for each step shown and 0 for those steps that are not demonstrated, therefore the "total DK-crush step score" (TDCS) was calculated for each video. Our aim was to evaluate the compatibility of the videos with the reference article. In addition, it was aimed to evaluate videos with HONcode, JAMA benchmark and modified DISCERN tools which are instruments to evaluate the reliability, credibility and quality of the medical information served on the internet. A total of 26 videos met inclusion criteria and were included in the analysis. The median number of views of the videos was 1037 (IQR 194 to 4930) with a median duration of 8.55(IQR 3.19 to 15.2). The median number of the criteria consistent with the reference criteria was 12 (IQR 9,25 to 12), most videos met all the essential criteria and have certain amount of correlation with the scoring systems. Although most videos were compatible with the reference technique, we found mild correlation between modified Discern score and total DK-Crush step score. Furthermore when comparing the number of views, likes, duration of video, HONcode score and the total DK-crush step score(TDCS) were likely to be higher in the videos downloaded or presented by individuals with academic degrees.( p:0.004,p:0.02, p:0.02, p:0.02, p:0.03 respectively). All of the videos on DK crush was prepared by healthcare professionals yet not all the uploaders or presenters in the videos have academic titles. Those videos in which DK-Crush technique was performed and presented by those with academic degrees are likely to be more instructive according to our results. Compared to the reference publication, most videos were compatible in terms of fitting the procedural steps of DK-crush. Among all videos HONcode and JAMA score has no correlation with DK-Crush step scores, yet modified Discern has mild correlation with total DK-crush step score.
