Objective: This study evaluated online thyroid cancer patient information quality. This is essential, given increasing patient use of online health information. Methods: A total of 100 thyroid cancer websites, representing those patients find first, were identified using Google and two meta-search engines. Content accuracy and patient-evaluable quality markers, including attribution, currency, structure, and content comprehensiveness and readability, were assessed with a previously validated standardized rating tool, developed using design-based methods. Accuracy was defined compared to standard, peer-reviewed medical resources, UpToDate and the National Comprehensive Cancer Network. Responses to general and personal "patient" questions were evaluated for promptness and accuracy. Results: Of 100 websites, only 26% stated authorship, and 56% cited sources. Seventy-four percent had dates of creation or last update, with only half of those dates occurring within the past 2 years. Websites most often discussed the definition (94%), diagnosis (92%), and treatment (94%) of thyroid cancer, but diagnosis and treatment were also most frequently incomplete or inaccurate: diagnosis information was complete and accurate 50% of the time, and treatment 47%. Only 2% of websites were comprehensible without high school education. Of 83 websites contacted with "patient" questions, 50 replied, 48 within 1 week. Conclusion: Thyroid cancer information is widely available online, but quality varies. Sites often lack markers for patients to assess quality, and content may be difficult to understand. Information is frequently incomplete, particularly on topics important to patients, such as diagnosis and treatment. Educational resource developers may fill these gaps, and healthcare providers can direct thyroid cancer patients to reliable online resources.
