Medical reliability of a video-sharing website: the gingival recession model.
European Journal of Dental Education : Official Journal of the Association for Dental Education in Europe 2019 January 12
OBJECTIVES: To evaluate the quality of the scientific/clinical information in dentistry delivered by videos hosted by a popular video-sharing website.
METHODS: The gingival recession condition was used as a model, and YouTube TM as the video hosting service. A systematic observation of videos containing information on gingival recession was conducted. Videos were analyzed to evaluate (1) the scientific reliability and quality of the information using Global Quality Scale (GQS) and DISCREN criteria; and (2) the understandability of this information using a tailor-made custom comprehensiveness index (CI).
RESULTS: One hundred and eighty videos were identified. Videos dealing with surgical procedures were not included in the present review. After selection, forty-one videos were analyzed. The mean GQS was 2.34 on a 0-5 scale, and twenty-five (61%) videos showed clear aims according to DISCREN criteria. Misleading content was observed in eight videos (19.5%). The scientific sources of information were unclear in twenty-six (63.4%) videos. All videos failed to give additional references for supplemental information. Only three videos (7%) provided basic information on etiology, clinical presentations, and management of gingival recession. Based on 0-2 CI scores, three, nine, and twenty-nine videos had a score of 2, 1, and 0, respectively.
CONCLUSION: The present model indicates that social media websites aiming to provide health information should be carefully accounted, especially when dealing with dentistry. It also suggests professional involvement to improve the quality of the delivered information. This article is protected by copyright. All rights reserved.
