Background
Homemade cloth products are increasingly being used as a preventive measure against COVID-19, with various methods promoted through do-it-yourself (DIY) videos available on YouTube and other websites. While guidance has been provided by key organisations on how to create face masks, the extent to which this is being accurately disseminated is currently unknown.
Methods
A key word search of YouTube using the terms “face/cloth mask” and “diy face/cloth mask” was completed on 18 April 2020. Total and category video content scores determined using the 18-point scoring system in the author-designed checklist. Criteria grouped by: reasons and caveats for use (three criteria), manufacturing instructions (six criteria), instructions for use (five criteria), re-use (three criteria), and cleaning instructions (one criteria). Total scores of ≥ 9 were classified as useful, and those < 9 classified as not useful out of a maximum score of 18.
Results
Of the 400 videos screened, 261 videos were retained for analysis. 91.7% (n = 242) were categorised as non-useful, compared to 8.3% (n = 22) as useful. Overall, useful videos scored higher across all assessed content evaluation categories. Manufacturing instructions were the most common content featured in the videos, with re-use and cleaning instructions featuring the least.
Conclusions
Currently, there is a lack of comprehensive, best-practice information on face masks being disseminated through YouTube. The information gaps identified in these findings present an opportunity for authoritative sources to focus communication efforts on promoting best-practice guidance while advice continues to be updated on universal face mask use.
