A total of 117 videos were included in the study. The median length of the videos was 14.10 (range = 6.59-30.03) minutes. The median number of views was 590.50 (range = 144.00-2674.00). A significant portion of the videos (n = 94, 77.7%) had been uploaded by healthcare providers. Although the videos generally focused on surgeons (number of videos = 72, 61.5%), there were 45 (38.5%) videos targeting general audience. Table I shows the characteristics of the videos. When the videos were evaluated according to the questionnaires, although the viewing rates differed according to the DISCERN groups, the increase was not linear. Furthermore, the number of views per day and the median number of likes did not differ (Table II). However, when GQS was evaluated, the median values for the number of views, views per day and likes increased in the videos with a GQS of >3 (p = 0.019, p = 0.019, and p = 0.009, respectively).
When the data were divided into Group 1 and Group 2 according to the upload source, the median number of views was 643.50 (range = 155.00-2331.00) and 520.00 (range = 181.00-8547.00), respectively, indicating a slightly higher value for healthcare providers, albeit with no significant difference (p = 0.916) (Table III). There was no statistically significant difference between the upload source groups in terms of the median number of views (per day), median number of likes, reliability score, DISCERN score, and GQS of the videos (p = 0.470, p = 0.163, p = 0.249, p = 0.484, andp = 0.108, respectively). However, when PEMAT was evaluated, the understandability scores [Group 1 = 73.33 (range = 60.00-92.86) and Group 2 = 93.33 (range = 80.00-100.00)] and actionability scores [Group 1 = 75.00 (range = 50.00-100.00) and Group 2 = 100 (range = 50.00-100.00)] were statistically significantly higher in Group 2 (p = 0.004 and p = 0.022, respectively). Furthermore, according to the results of the misinformation scale, Group 1 had uploaded more videos with low-degree misinformation [Group 1 = 31 (34.4%)] and Group 2 = 7 (25.9%)] while Group 2 was the source of more videos with high-degree misinformation [Group 1 = 5 (5.5%) and Group 2 = 9 (33.3%)]. There was a statistically significant difference between the two groups in terms of misinformation evaluation (p = 0.001).
