Objectives: The internet has become one of the most important resources for the general population when searching for healthcare information. However, the information available is not always suitable for all readers because of its difficult readability. We sought to assess the readability of online information regarding the novel coronavirus disease (COVID-19) and establish whether they follow the patient educational information reading level recommendations. Study design: This is a cross-sectional study. Methods: We searched five key terms on Google and the first 30 results from each of the searches were considered for analysis. Five validated readability tests were utilized to establish the reading level for each article. Results: Of the 150 gathered articles, 61 met the inclusion criteria and were evaluated. None (0%) of the articles met the recommended 5th to 6th grade reading level (of an 11-12-year-old). The mean readability scores were Flesch Reading Ease 44.14, Flesch-Kincaid Grade Level 12.04, Gunning-Fog Index 14.27, Simple Measure of Gobbledygook SMOG Index 10.71, and Coleman-Liau Index 12.69. Conclusions: Online educational articles on COVID-19 provide information too difficult to read for the general population. The readability of articles regarding COVID-19 and other diseases needs to improve so that the general population may understand health information better and may respond adequately to protect themselves and limit the spread of infection.

Summary YouTube is the second most popular website in the world and is increasingly being used as a platform for disseminating health information. Our aim was to evaluate the content‐quality and audience engagement of YouTube videos pertaining to the SARS (severe acute respiratory syndrome)‐CoV‐2 virus which causes the Coronavirus Disease 2019 (COVID‐19), during the early phase of the pandemic. We chose the first 30 videos for seven different search phrases: “2019 nCoV,” “SARS CoV‐2,” “COVID‐19 virus,” “coronavirus treatment,” “coronavirus explained,” “what is the coronavirus” and “coronavirus information.” Video contents were evaluated by two independent medical students with more than 5 years of experience using the DISCERN instrument. Qualitative data, quantitative data and upload source for each video was noted for a quality and audience engagement analysis. Out of the total 210 videos, 137 met our inclusion criteria and were evaluated. The mean DISCERN score was 31.33 out of 75 possible points, which indicates that the quality of YouTube videos on COVID‐19 is currently poor. There was excellent reliability between the two raters (intraclass correlation coefficient = 0.96). 55% of the videos discussed prevention, 49% discussed symptoms and 46% discussed the spread of the virus. Most of the videos were uploaded by news channels (50%) and education channels (40%). The quality of YouTube videos on SARS‐CoV‐2 and COVID‐19 is poor, however, we have listed the top‐quality videos in our article as they may be effective tools for patient education during the pandemic.

YouTube is the world's most popular video-sharing site ("Top 15 Most Popular Video Websites | January 2020," n.d.). It is not only used for entertainment purposes but in recent years YouTube has expanded to become a platform for education. Formerly, patients would rely solely on their physician as a source of information, whereas current data shows that the internet is becoming an increasingly credible database. Studies show that patients and their families use internet sites such as YouTube to provide educational information about their disease, possible treatment options and management of daily life

Background: Previous studies on the novel Coronavirus (COVID-19) have found strong correlations between online searches and the epidemiology of the disease. Aim: Our aim was to determine if online searches for COVID-19 related to international media announcements or national epidemiology. Methods: Searches for "coronavirus" were made on Google Trends from December 31, 2019 to April 13, 2020 for 40 European countries. The online COVID-19 searches for all countries were correlated with each other. COVID-10 epidemiology (i.e. incidence and mortality) was correlated with the national online searches. Major announcements by the World Health Organization (WHO) were taken into consideration with peaks in online searches. Correlations were made using Spearman's rank correlation coefficient. Results: Overall, the online searches for COVID-19 were not correlated with the actual incidence and mortality of COVID-19. The mean Spearman correlation for incidence was 0.20 (range À0.66 to 0.76) and for mortality was 0.35 (range À0.75 to 0.85). Online searches in Europe were all strongly synchronized with each other; a mean Spearman correlation of 0.93 (range 0.62 to 0.99). Conclusions: Online searches for COVID-19 in Europe are not correlated with epidemiology but strongly correlated with international WHO announcements. Our study challenges previous Google Trends studies and emphasizes the role of the WHO in raising awareness of a new disease.

Background: Stroke is the second leading cause of death worldwide following ischemic heart disease, and the fifth in the United States. The video-sharing database, YouTube, is the second most popular visited website with more than 2 billion users, thus it's increasingly being used as a medium for delivering health information. Aim: We aimed to evaluate the quality, reliability and audience engagement of stroke-related YouTube videos. Methods: In October 2019 we conducted a search on YouTube using 5 keywords: stroke, brain attack, hemorrhagic stroke, ischemic stroke and transient ischemic attack. We selected the first 30 videos from each search query for further analysis. The validated DISCERN instrument was used (a score of 0-5 per question) to assess the videos by four independent raters. We then recorded qualitative data and quantitative data for each video. Results: After sorting through 150 stroke videos, a total of 101 unique YouTube videos met our inclusion criteria. We found that the mean overall quality of YouTube videos according to DISCERN is of fair quality. Most videos (65.3%) were uploaded by hospitals, mentioned the symptoms of stroke (66.3%), had a doctor speaking (60.4%) and contained diagrams (20.8%). Conclusion: YouTube is a useful source of gathering information about treatment choices for patients and their families as the quality of You-Tube videos is fair. The audience engagement suggestions in our paper may help content creators improve the appeal of YouTube videos.
