YouTube is heavily utilized by patients as an educational resource, but this content can be fraught with misinformation. We sought to characterize the quality of videos on YouTube discussing postprostatectomy erectile dysfunction and to evaluate metrics associated with retaining a top position in search results over time.
In October 2019, we watched the first 100 YouTube videos using the search query "radical prostatectomy erectile dysfunction." Videos not relevant to the topic were excluded. Video metrics were collected, and content quality was evaluated using the DISCERN instrument. In June 2022, the search was repeated and video metrics were updated. Video characteristics were associated with search rank and the ability to remain in the top 100 spots using the Pearson correlation coefficient (r) and logistic regression, respectively.
We included 81 videos which amassed 529,428 views in 2019. The median total DISCERN score was 29 (IQR 21-42), which is interpreted as a poor quality video. Self-promotion or commercial bias was present in 42 videos (51.9%); false claims were present in 16 (19.8%). There was no correlation between DISCERN score and search rank (r = 0.08, p = 0.49). In 2022, 15 videos remained in the top 100 search results and had a higher median DISCERN score than videos no longer in the top 100 (46 vs. 28.5, p = 0.01). Each additional DISCERN point was associated with a 7% higher odds of remaining in the top 100 (OR 1.07, 95% CI 1.01-1.11, p = 0.003).
The quality of the top 100 YouTube videos discussing postprostatectomy erectile dysfunction is low. Higher quality videos had a higher odds of remaining in the top 100 search results over time but do not correlate with the order in which they are ranked.
YouTube 被患者广泛用作教育资源，但其中的内容可能存在错误信息。我们旨在描述讨论前列腺癌根治术后勃起功能障碍的 YouTube 视频的质量，并评估随着时间的推移与在搜索结果中保持较高排名相关的指标。
2019 年 10 月，我们使用搜索查询“radical prostatectomy erectile dysfunction”观看了前 100 个 YouTube 视频。排除与主题无关的视频。收集视频指标，并使用 DISCERN 工具评估内容质量。2022 年 6 月，重复搜索并更新视频指标。使用 Pearson 相关系数（r）和逻辑回归分别将视频特征与搜索排名和保持在前 100 名的能力相关联。
我们共纳入 81 个视频，这些视频在 2019 年获得了 529,428 次观看。中位总 DISCERN 评分为 29（IQR 21-42），提示视频质量较差。42 个视频（51.9%）存在自我推销或商业偏见；16 个视频（19.8%）存在虚假声明。DISCERN 评分与搜索排名之间无相关性（r=0.08，p=0.49）。2022 年，有 15 个视频仍在前 100 名搜索结果中，其 DISCERN 评分中位数高于不再在前 100 名的视频（46 对 28.5，p=0.01）。每个额外的 DISCERN 点与在前 100 名中排名更高的几率增加 7%相关（OR 1.07，95%CI 1.01-1.11，p=0.003）。
讨论前列腺癌根治术后勃起功能障碍的前 100 个 YouTube 视频质量较低。随着时间的推移，质量较高的视频在前 100 名搜索结果中排名更高的几率更高，但与它们的排名顺序无关。
