The goal of this study was to determine whether the informative quality of videos of endoscopic third ventriculostomy (ETV) and endoscopic third ventriculostomy with choroid plexus cauterization (ETV + CPC) is associated with metrics of popularity.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>This cross-sectional study used comprehensive search terms to identify videos pertaining to ETV and ETV + CPC presented on the first 3 pages of search results on YouTube. Two pediatric neurosurgeons, 1 neurosurgery resident, and 2 patient families independently reviewed the selected videos. Videos were assessed for overall informational quality by using a validated 5-point Global Quality Score (GQS) and compared to online metrics of popularity and engagement such as views, likes, likes\/views ratio, comments\/views ratio, and likes\/dislikes ratio. Weighted kappa scores were used to measure agreement between video reviewers.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>A total of 58 videos (47 on ETV, 7 on ETV + CPC, 4 on both) of 120 videos assessed met the inclusion criteria. Video styles included \u201ctechnical\u201d (62%), \u201clecture\u201d (24%), \u201cpatient testimonial\u201d (4%), and \u201cother\u201d (10%). In terms of GQS, substantial agreement was seen between surgeons (kappa 0.67 [95% CI 0.55, 0.80]) and excellent agreement was found between each surgeon and the neurosurgical resident (0.77 [95% CI 0.66, 0.88] and 0.89 [95% CI 0.82, 0.97]). Only fair to moderate agreement was seen between professionals and patient families, with weighted kappa scores ranging from 0.07 to 0.56. Academic lectures were more likely to be rated good or excellent (64% vs 0%, p &lt; 0.001) versus surgical procedure and testimonial video types. There were significant associations between a better GQS and more likes (p = 0.01), views (p = 0.02), and the likes\/dislikes ratio (p = 0.016). The likes\/views ratio (p = 0.31) and comments\/views ratio (p = 0.35) were not associated with GQS. The number of likes (p = 0.02), views (p = 0.03), and the likes\/dislikes ratio (p = 0.015) were significantly associated with video style (highest for lecture-style videos).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>Medical professionals tended to agree when assessing the overall quality of YouTube videos, but this agreement was not as strongly seen when compared to parental ratings. The online metrics of likes, views, and likes\/dislikes ratio appear to predict quality. Neurosurgeons seeking to increase their online footprint via YouTube would be well advised to focus more on the academic lecture style because these were universally better rated.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2019.12.peds19523","type":"journal-article","created":{"date-parts":[[2020,3,5]],"date-time":"2020-03-05T18:48:51Z","timestamp":1583434131000},"page":"607-614","source":"Crossref","is-referenced-by-count":5,"title":["The quality of YouTube videos on endoscopic third ventriculostomy and endoscopic third ventriculostomy with choroid plexus cauterization procedures available to families of patients with pediatric hydrocephalus"],"prefix":"10.3171","volume":"25","author":[{"given":"Nicholas","family":"Sader","sequence":"first","affiliation":[{"name":"Department of Clinical Neurosciences, Division of Neurosurgery, Alberta Children\u2019s Hospital, University of Calgary, Alberta, Canada;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abhaya V.","family":"Kulkarni","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Hospital for Sick Children, University of Toronto, Ontario, Canada; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew E.","family":"Eagles","sequence":"additional","affiliation":[{"name":"Department of Clinical Neurosciences, Division of Neurosurgery, Alberta Children\u2019s Hospital, University of Calgary, Alberta, Canada;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salim","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Department of Clinical Neurosciences, Division of Neurosurgery, Alberta Children\u2019s Hospital, University of Calgary, Alberta, Canada;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenna E.","family":"Koschnitzky","sequence":"additional","affiliation":[{"name":"Hydrocephalus Association, Bethesda, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jay","family":"Riva-Cambrin","sequence":"additional","affiliation":[{"name":"Department of Clinical Neurosciences, Division of Neurosurgery, Alberta Children\u2019s Hospital, University of Calgary, Alberta, Canada;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Fact Tank","article-title":"5 facts about online video, for YouTube\u2019s 10th birthday","author":"Anderson M","unstructured":"Anderson M: 5 facts about online video, for YouTube\u2019s 10th birthday.
