RESUMEN
BACKGROUND: YouTube is one of the most widely accessed platforms for patients seeking information across all medical specialties. More than 50% of patients engage with online information before seeing a physician. There has been no qualitative analysis of neuromodulation content on YouTube. METHODS: By evaluating the search interest of neuromodulation terms via Google Trends, the authors selected 3 search terms to assess on YouTube. For each term, the top 20 videos were selected, 10 sorting by view count and 10 by relevance. DISCERN criteria were used to evaluate each video. Statistical analysis was performed with R software to discover associations among video characteristics and DISCERN scores (DSs). RESULTS: Neuromodulation, deep brain stimulation, and spinal cord stimulation terms were searched. There were 52 unique and 8 duplicate videos, which were excluded. The videos received 6,984,743 combined views (134,321 average). Neurosurgeons were the most common authors, producing 22 videos, followed by anesthesiologists with 10 videos. Statistical analysis showed that videos that were sponsored (DS 44.79 vs. 34.53; P < 0.011), had board-certified physicians (DS 42.88 vs. 31.25; P < 0.004), and had credentials of the video producer (DS 41.82 vs. 34.42; P < 0.044) were more likely to have higher DSs. Spinal cord stimulation videos had the lowest quality of the search terms (DS 30.9 vs. 39.2, 42.6; P < 0.043). CONCLUSIONS: Certain characteristics of YouTube videos are associated with higher quality. Video producers should aim to use these characteristics and follow DISCERN criteria when preparing online videos.
