Dr. Morata, left, is a research audiologist at the National Institute for Occupational Safety and Health (NIOSH) and the director of the Safe-in-Sound Excellence in Hearing Loss Prevention Awards. Dr. Chadha is the technical officer of the World Health Organization's Programme for Prevention of Deafness and Hearing Loss.

Over six percent of the world's population has disabling hearing loss.1 Across the globe, it can take years for those with hearing problems to seek care. Even when care is sought, the prescribed interventions are not often adopted.2 This issue has motivated the World Health Organization to coordinate World Hearing Day (WHD), an annual event that aims “to raise awareness on how to prevent deafness and hearing loss and promote ear and hearing care across the world.”3

The Centers for Disease Control and Prevention argues that “plain language makes it easier for everyone to understand and use health information,”4 emphasizing its commitment to making high-quality information freely accessible to the public.5 As health articles on Wikipedia are collectively read more than 150 million times per month,6 one approach the National Institute for Occupational Safety and Health is taking to communicate research findings involves improving health content on Wikipedia.7 That includes the adoption by university programs of the WikiEducation Foundation platform to train students in Wikipedia editing. Through this mechanism, students contribute evidence-based content to Wikipedia as a class assignment.9

This year, NIOSH proposed and developed the online event Wiki4WorldHearingDay2019 to facilitate the improvement of Wikipedia content related to hearing, hearing health services, hearing testing, and preventive and rehabilitative interventions. The platform provided guidance and allowed anyone with access to a computer and the internet to participate in the campaign. Several institutions joined by either promoting the event or contributing content to Wikipedia, including the National Center for Environmental Health, the National Center on Birth Defects and Developmental Disabilities, the Hearing Center of Excellence, the French National Research and Safety Institute for the Prevention of Occupational Accidents, the International Society of Audiology, the Acoustical Society of America, the American Academy of Audiology, and Hear in Cincinnati Participants from Cochrane, Cochrane Ear, Nose and Throat, and university programs in the United States, Canada, United Kingdom, Brazil, and South Africa also contributed expert content, which led to content being added in English, Portuguese, French, Spanish, Italian, and Swedish.

Through the Wikimedia outreach dashboard,11 we were able to monitor the contributions and their reach with a great level of detail. Tracking data from the platform launch on Jan. 21, 2019, to March 31, 2019, showed that 74,000 words were contributed to 90 existing and seven new Wikipedia articles, and 21 images were donated to the open access repository WikiCommons. These pages received more than 2 million views (the 66 editors must be delighted to see this level of readership!).

Crowdsourcing of expertise and knowledge is relevant for public health. The transparency of editorial processes and engagement on Wikipedia make it easier for experts to address any concerns they might have over participation. The heightened level of review of Wikipedia health articles is only possible due to the generous dedication of contributors who are health professionals and collaborative ventures, such as Wiki4WorldHearingDay2019, with scientific associations and agencies.12 We encourage organizations and institutions across the world to join current and future efforts.13

The breadth and accuracy of the Wikipedia coverage of the sciences vary widely. Awareness campaigns present unique opportunities to make hearing-related content one of the better developed domains within Wikipedia while providing quality information to the global audience in a place where they actually look for it.
