Gamma Knife radiosurgery was introduced in the 1960s and is currently used worldwide. The internet has become a foremost source of information used by patients and their families. In this study, we aim to evaluate the accuracy and reliability of the Gamma Knife radiosurgery-related YouTube videos.
We searched YouTube and the first 3 pages sorted according to "Relevance-Based Ranking" were included for analysis. Four independent health care workers from different disciplines evaluated the videos using the validated DISCERN tool.
Our search resulted in 65,774 videos, and 14 videos met inclusion criteria. Our study found that 50% (7 of 14) of the videos were uploaded by university-affiliated hospitals; 14% of videos scored 3. The search term "Radiosurgery for intraaxial brain lesions" had the highest percentage of moderate videos (DISCERN = 3) (50%).
Patients and caregivers turn to online sources to gather information about the disease. However, the available YouTube published videos are published without proper academic monitoring, as in such a free platform, published videos tend to catch a general audience for different purposes, which leads to diminishing quality control. Academic medical institutions should consider a proper monitoring process for videos to improve the accuracy of the published information for the patients.
伽玛刀放射外科手术于 20 世纪 60 年代推出，目前在全球范围内使用。互联网已成为患者及其家属使用的首要信息来源。在这项研究中，我们旨在评估与伽玛刀放射外科手术相关的 YouTube 视频的准确性和可靠性。
我们在 YouTube 上进行了搜索，并纳入了根据“相关性排名”排序的前 3 页的视频。来自不同学科的 4 名独立医疗保健工作者使用经过验证的 DISCERN 工具评估了这些视频。
我们的搜索结果有 65774 个视频，符合纳入标准的有 14 个视频。我们的研究发现，50%（14 个视频中的 7 个）的视频是由大学附属医院上传的；有 14%的视频得分为 3 分。搜索词“颅内轴内病变的放射外科手术”的中度视频（DISCERN=3）（50%）比例最高。
患者和护理人员会转向在线资源来获取有关疾病的信息。然而，YouTube 上发布的可用视频是在没有适当学术监督的情况下发布的，因为在这样一个自由的平台上，发布的视频往往会因为不同的目的吸引普通观众，从而导致质量控制下降。学术医疗机构应该考虑对视频进行适当的监控流程，以提高为患者发布的信息的准确性。
