Personal protective equipment in Covid-19: Evidence-based quality and analysis of YouTube videos after one year of pandemic

Background: The correct use of personal protective equipment (PPE) during the Covid-19 pandemic is mandatory to minimize the contagion risk. The current study aimed to evaluate quality information of YouTube videos on PPE use during the pandemic. Methods: Using Google Trend tool, the frequency of worldwide YouTube and Google searches for "donning and doffing" was examined. We queried YouTube with terms related to donning and doffing of PPE. Validated quality information assessment tools were used. Results: From the December 1, 2019 to the January 31, 2021, according to YouTube and Google searches, both peaks occurred in April 2020 (69.5% and 72.0%, respectively). Of all videos, 144 were eligible for the analyses. According to misinformation tool, 90 (62.5%) videos contained inaccuracies. The median DISCERN Section 1 ranged from 3 to 5. The median DISCERN Section 3 was 4. According to Global Quality Score, 8.3% (n = 12), 14.6% (n = 21), 22.9% (n = 33), 30.6% (n = 44) and 23.6% (n = 34) were classified as poor, partially poor, moderate, partially good and excellent quality videos, respectively. Conclusions: Nowadays, YouTube may be recommended as a reliable source of information. Nevertheless, a not negligible number of videos contained inaccuracies. Future authors should improve videos contents to provide more complete information.
