Objectives: This study aimed to evaluate the quality and readability of web pages providing information about hand osteoarthritis using several authorized methods.Methods: A web page exploration was performed using the Google internet search engine. The three search terms, "hand osteoarthritis," "finger osteoarthritis," and "hand OA," were used and the top 100 ranked websites were selected and divided into six categories. The Health on the Net Foundation (HON) grade scale, an instrument for judging the quality of written consumer health information on treatment choice (DISCERN instrument), and the Ensuring Quality Information for Patients (EQIP) score were used to evaluate the quality of each website. The Flesch-Kincaid reading ease (FRE) score, Flesch-Kincaid grade (FKG) level, Gunning-Fog index, and Simple Measure of Gobbledygook grade level were used to evaluate website readability.Results: Among 300 websites, 57 websites were selected following exclusion criteria. News portal websites, including the online version of newspapers and periodicals, showed the highest score in all three quality evaluation tools. Only four websites were regarded as high-quality websites based on the HON grade scale (n = 3) and the EQIP score (n = 1). Each type of website showed an average FKG level higher than 7th grade and obtained an average FRE score of less than 80 points, indicating an inappropriate level for a layperson to read.Conclusions: The online information about hand osteoarthritis is low quality and difficult to read for the general public. There is a need to enhance the quality and readability of web-based information related to hand osteoarthritis for patients to obtain credible information and receive proper treatment for the disease.
