Among 59 videos were included in the study, 52 (88.14%) were on patient history, nine (15.24%) were on progress notes, and two (3.39%) were on both patient history and progress notes. Some descriptive statistics of the videos included in the study are shown in Table 1. Five videos reached more than 90% of comprehensiveness, while only one of them included all aspects of clinical record-keeping (https://www.youtube.com/watch?v=j0MsR-1e9ww).

Of 59 videos, 14 (23.72%) specifically utilized the SOAP (subjective, objective, assessment, plan) note-taking method.
In the evaluation of the videos' affiliation with specific specialties, the number of videos related to specialties are as follows: Pulmonology (three videos), obstetrics (three videos), psychiatry (two videos), surgery (two videos), neurology, ophthalmology, clinical pharmacology, and intensive care (one video for each). Remained 45 (76.27%) videos were not specific to any specialty.
Upon evaluating the characteristics of the uploaders, it was found six (10.17%) videos were uploaded by universities or professional associations/organizations, five (8.47%) by individual academics, 33 (55.93%) by non-academic physicians or medical students, 11 (18.64%) by non-physician healthcare professionals, and three (5.08%) by non-healthcare professionals. The uploader of one (1.69%) video could not be classified. Group-based descriptive statistics are presented in Table 2.

In the examination of the countries from which the videos were uploaded, it was observed that 18 (30.51%) videos were from India, 15 (25.42%) from the United States, eight (13.56%) from the United Kingdom, four (6.78%) from Canada, three (5.08%) from Pakistan, two (3.39%) from the Philippines, and one (1.69%) each from Egypt, Nigeria, and South Africa. The origin countries of six (10.17%) videos could not be found. In a video uploaded by a university/professional organization, we excluded evaluation of likes, dislikes, and comments. Additionally, in a video uploaded by an individual academic, comments were not assessed. The reason was that these features were disabled in the videos.
Due to the limited number of uploaders in certain groups, group-based comparison was made by combining “universities or professional associations/organizations” and “individual academics” as the first group, others as the second group, which has been shown in Table 3. When uploader groups were divided into these two group, there was no significant difference in comprehensiveness score (p = 0.131). However, the first group (14.64 ± 2.38) outperformed the second group (10.43 ± 3.41) in IVQC score, and the difference was significant (p < 0.001).
