The Reliability of YouTube Videos Describing Stereotactic Radiosurgery: A Call for Action.

BACKGROUND: 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. METHODS: 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. RESULTS: 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%). CONCLUSIONS: 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.
