Abstract

Background
YouTube is one of the most popular video-sharing websites in Korea, but incorrect or biased information is not properly regulated. Acne is common in adolescents and young adults who are familiar with YouTube. Thus, misleading information about isotretinoin in YouTube videos could distort the perception of treatment.
Objective
We evaluated the quality of information about isotretinoin in YouTube videos.
Methods
The keywords searched on YouTube Korea on July 1, 2020 were: isotretinoin, Roaccutane, and Isotinone. The DISCERN tool was used to evaluate the reliability and quality of information, and eight items were used to evaluate scientific accuracy and comprehensiveness: mechanism, indications, dose regimen, contraindications, side effects, blood tests, drug interactions, and pregnancy-related issues.
Results
The number of videos searched was 728. After excluding duplicate or inappropriate videos, 164 videos were analyzed. In the DISCERN tool, the mean overall quality score was 2.24 on a 5-point scale from 1 to 5. The mean score in the 8-issue-criteria, a 3-point scale from 0 to 2, was 0.61. Particularly, indications, blood tests, and drug interactions were poorly addressed in YouTube videos. Medical personnel offer better video quality than non-medical personnel. However, no significant difference in quality existed between the videos of dermatologists and those of other medical personnel. The quality score was not correlated with the popularity of the video.
Conclusion
YouTube videos covering isotretinoin showed poor overall quality. Content quality did not have a significant correlation with popularity, so incorrect information could be propagated on YouTube.
