Abstract
PURPOSE
Diabetic macular edema (DME) is a vision-threatening complication of diabetes mellitus due to increased vascular permeability. Patients are increasingly using YouTube videos to educate themselves about DME. This study analyzes the content and quality of YouTube videos about DME.
METHODS
Videos were searched in December 2021 for "diabetic macular edema." The first 100 videos sorted by both relevance and view count were reviewed (n = 200). Quantitative metrics and content were collected. Two reviewers assessed videos using the JAMA (0-4), modified DISCERN (1-5), and Global Quality Scale (GQS, 1-5). Videos were sorted into author groups: 1 (academic institutions/organizations), 2 (private practices/organizations), and 3 (independent users; ophthalmologist users noted). Statistical analyses were deemed significant at a = 0.05.
RESULTS
One hundred four videos were included after applying exclusion criteria. Overall mean + standard deviations were 2.25 ± 0.83 (JAMA), 3.47 ± 0.55 (DISCERN), and 3.95 ± 0.95 (GQS). 51.9% of videos stated a definition, 32.7% mentioned screening, and 50% mentioned any DME risk factor. Healthcare professional-targeted videos had higher JAMA and DISCERN scores than patient-targeted videos (p < 0.05). Videos using ophthalmologists had higher JAMA and DISCERN scores than those lacking their presence (p < 0.05). JAMA scores significantly varied between author groups; within group 3, ophthalmologist-authored videos had higher DISCERN scores (p < 0.05).
CONCLUSION
Videos without ophthalmologists or targeted toward patients had poor quality and content coverage. The rising prevalence of diabetes, coupled with increased internet use for acquiring medical information, creates a strong need for high-quality information about DME.
