Assessment of the Quality and Reliability of YouTube as an Information Source for Transforaminal Interbody Fusion.

BACKGROUND

This study aims to assess the quality and reliability of the information for patients from YouTube videos on transforaminal interbody fusion (TLIF).

MATERIAL AND METHODS

One hundred videos were listed by inputting "TLIF," "TLIF surgery," and "transforaminal interbody fusion" in the YouTube search engine. The top 50 most popular videos based on video power index (VPI), view ratio, and exclusion criteria were selected for review. One orthopedic consultant surgeon and one neurosurgeon consultant analyzed the videos together. The modified DISCERN score, the Global Quality Score (GQS), the Journal of the American Medical Association (JAMA) score, and a novel interbody fusion score were used to evaluate videos. Data of video length, view count, number of likes and dislikes, like ratio (like x 100/(like+dislike)), video source, and comment rate were collected.

RESULTS

The quality of the videos could have been better according to all scoring systems, regardless of the video source. The scores of the videos published by patients and commercials were significantly lower than those of physicians and allied professionals (p <0.05). VPI and view ratios were similar in all sources.  Conclusion: The study demonstrates that YouTube videos providing information related to TLIF surgery are available and accessed by the public. The results of this study would suggest that YouTube is not currently an appropriate source of information on TLIF surgery for patients. Most of the YouTube videos about TLIF surgery contain information about the surgical technique and have limited information about the post-operative condition of the patients.
