Accessibility Analysis of Worldwide COVID-19-Related Information Portals

Abstract

Since the beginning of the COVID-19 pandemic, communication technology has demonstrated its usefulness in sharing and receiving health data and communicating with the public. This study evaluated the accessibility of 199 websites containing official COVID-19 information related to medical schools, governments, ministries, and medical associations, obtained from the Geneva Foundation for Medical Education and Research website. We used the Web Content Accessibility Guidelines 2.1 to evaluate web accessibility, using a six-phase process with an automatic review tool. The study results reveal that the highest number of barriers encountered are concentrated in the perceivable principle with 6388 errors (77.8%), followed by operability with 1457 (17.7%), then robustness with 291 (3.5%), and finally understandability with 78 errors (0.9%). This study concludes that most COVID-19-related websites that provide information on the context of the pandemic do not have an adequate level of accessibility. This study can contribute as a guide for designing inclusive websites; web accessibility should be reviewed periodically due to technological advances and the need to adapt to these changes.

Diabetes Research and Resource Sharing During the COVID-19 Pandemic: A Systematic Review and Experience from an Academic/Non-Profit Resource Website

“…28 Because the general population heavily relies on the Internet to obtain information quickly, it is essential that health-related information found online during a pandemic is accurate and accessible. 29 In a review article, Stern and colleagues 28 reported that the articles found online one year after the confirmed COVID-19 outbreak were riddled with misinformation. Many websites and videos about COVID-19 were of poor quality and needed improvements, and none of the websites or videos met their metric of being good or of excellent quality.…”

An Accessible Serious Game-Based Platform for Process Learning of People with Intellectual Disabilities

“…The process applied was a combination between an automatic tool and manual review. In studying the parameters related to contrast and brightness, the automated tool WAVE [52] was used. In the evaluation, categories that met the parameters were scored with one (1) and zero (0) for those that did not.…”

Inertial Sensors for Hip Arthroplasty Rehabilitation: A Scoping Review

“…While a triaxial accelerometer can measure the proper linear acceleration of movements in a fixed three-dimensional (3D) frame per sensor, the estimated data includes components of motion and gravity. However, wearable sensors have not yet become standard in The growing interest in rehabilitation in January 2023 could be related to the growing concern for health and well-being, particularly after the COVID-19 pandemic [5]. There may be a greater interest in finding solutions and resources for rehabilitation in general.…”

“…Finally, Section 6 outlines the assumptions made in this study and identifies areas for future research. The growing interest in rehabilitation in January 2023 could be related to the growing concern for health and well-being, particularly after the COVID-19 pandemic [5]. There may be a greater interest in finding solutions and resources for rehabilitation in general.…”
