Audiovisual information of oral epithelial dysplasia: Quality, understandability and actionability

Online information on oral epithelial dysplasia (OED) is insufficient and of low quality. While only written information has been previously assessed, this study aims to evaluate the content and quality of audiovisual (AV) online information about OED.One hundred and twenty-seven materials were initially considered using six key words across two search engines (YouTube and Google). Ultimately, 29 materials remained for the final assessment. These materials were then analysed for content, quality (DISCERN instrument, JAMA benchmarks), understandability and actionability.Most contents were scientific (n = 25), while three videos were educational, and one video was a personal experience with OED. On a scale of 1-5, the overall DISCERN score was (mean ± SD = 2.26 ± 0.79), suggesting poor quality of information. Regarding JAMA benchmarks, there was no single material that fulfilled or lacked all four benchmarks. The overall mean understandability score was 82% and the actionability mean score was significantly low at 29%.Although the vast majority of AV materials on OED were primarily produced for scientific purposes, these materials could be helpful as resources for patient education. Keeping in mind, however, that the desired quality and essential patient information about OED available online remains largely poor and missing.
