Assessing the educational value of laparoscopic radical nephrectomy videos on YouTube®: A comparative analysis of short versus long videos.

Introduction: To evaluate the quality of laparoscopic radical nephrectomy videos and determine the extent to which they are informative and educational for healthcare professionals.

Patients and methods: We used the YouTube® search engine to search for the term 'laparoscopic radical nephrectomy' with time filters of 4-20 min (Group 1) and >20 min (Group 2) and then sorted the results uploaded chronologically before January 2023. One hundred videos were analysed for each group. The reliability of the videos was assessed using the Journal of American Medical Association (JAMA) Benchmark Criteria and DISCERN questionnaire scores (DISCERN). Educational quality was assessed using the Global Quality Score (GQS) and a 20-item objective scoring system (OSS) for laparoscopic nephrectomy. The popularity of the videos was evaluated using the video power index (VPI).

Results: The mean video duration was 8.9 ± 4.3 min in Group 1 and 52.02 ± 31.09 min in Group 2 (P < 0.001). The mean JAMA (2.49 ± 0.61) and OSS scores (60 ± 12.3) were higher in Group 2 than in Group 1, while no significant difference was observed in the mean GQS (2.53 ± 0.7, 2.39 ± 0.88, respectively) between the groups (P < 0.001, P = 0.039, P = 0.131, respectively).

Conclusion: While the standardisation of surgical videos published on YouTube® and the establishment of auditing mechanisms do not seem plausible, high total OSS, periprocedural OSS, and VPI scores, and high OSS, JAMAS, GQS and DISCERN scores in long videos indicate that such videos offer a greater contribution to education.
