Rosacea videos on social media: A comparison of accuracy, quality, and viewer engagement.

BACKGROUND

Little is known regarding the accuracy, quality, and viewer engagement of video-based online education.

OBJECTIVE

To assess the accuracy, quality, viewer engagement, and viewer experience of rosacea videos on social media.

METHODS

Reviewers searched "rosacea" and examined videos on YouTube in September 2018. Videos were categorized by source: 1) Healthcare sources: university/professional organizations, industry, and individuals that were healthcare professionals, and 2) Non-healthcare sources: lay media and individuals that were not healthcare professionals. Video accuracy was measured using the Dy et al. Accuracy Scale (DAS) and Accuracy in Digital-health Instrument (ANDI). Video quality was measured using the Global Quality Scale (GQS). Viewer engagement was measured by the engagement ratio (total likes+dislikes+comments/total views).

RESULTS

Of the videos analyzed, 71.7% of videos were from non-healthcare sources. Videos produced by healthcare sources (28.3%) were significantly more accurate than those produced by non-healthcare sources, as measured by ANDI (3.57±0.83 versus 2.54±1.07, P=0.001). Videos created by non-healthcare sources received significantly greater engagement than those by healthcare professionals (viewer engagement ratio 0.031±0.044 versus 0.014±0.013, P=0.0159).

CONCLUSION

Rosacea videos on social medi produced by non-healthcare sources were less accurate and of lower quality but received greater viewer engagement than those produced by healthcare sources.
