German YouTube(TM) videos a source of information on cutaneous melanoma: A critical appraisal.

YouTube(TM) is an openly accessible video-sharing platform that is increasingly used by melanoma patients to acquire disease-related information. Dissemination of medical information through such a platform may offer valuable opportunities, but also challenges as the quality of unfiltered information posted may be of low scientific quality(1) , or even be misleading. Additionally, the credibility of the providers cannot be verified.(2-4) Moreover, little is known about the value of such videos. Therefore, we aimed to identify YouTube(TM) videos on melanoma and to assess their quality, reliability, usability, and understandability.
