ObjectiveThe Internet is a source of health information for patients. Quality of information available to patients is varied and uncontrolled. Physicians should be familiar with the overall quality of the information. This review provides an evaluation of YouTube's current patient accessible health information on the topic of lumbar disc herniation (LDH).MethodsYouTube was queried using 3 different search strings: (1) "disc herniation", (2) "lumbar disc herniation", or (3) "lower back disc herniation". Video duplicates, non-English, or those that contained no audio or were not relevant to LDH were excluded. The first 50 videos per search string were evaluated. Two reviewers independently assessed videos. Parameters included duration, upload date, number of views, number of likes, views per day, and likes per day. A scoring system was used to grade the videos for their performance on diagnosis and treatment of LDH.ResultsThe first 50 videos produced a total number of hits of 50,500, 29,100, and 22,100, respectively. Strong agreement, assessed using intraclass correlation coefficient (ICC), was demonstrated between readers for both diagnostic scores (ICC 0.921, 95% CI 0.866-0.953) and treatment scores (ICC 0.916, 95% CI 0.855-0.951). Educational Physician videos had significantly greater diagnostic and treatment scores compared to non-physician videos (9.54 vs. 7.05, P = 0.048, and 6.53 vs. 5.3, P = 0.004).ConclusionsYouTube videos pertaining to LDH were found to have low overall quality. Physicians should be cognizant about information sources readily available to patients as they may influence patient expectations and preconceptions.Copyright © 2023 Elsevier Inc.
