Patients increasingly use the Internet for gastric cancer information. However, the quality of the information is questionable. We evaluated the accuracy, completeness, accessibility, reliability, and readability of gastric cancer websites.
The Internet was searched for the terms "gastric cancer" or "stomach cancer" using general search engines. Websites were evaluated for completeness (CS) and accuracy (AS) using predefined quality appraisal instruments (QAIs), reliability using an integrity score (IS), readability using the Flesch-Kincaid (FK) grade level, and accessibility using automated accessibility appraisal tools. Site sponsor and the presence of quality labels were noted.
Fifty-one websites were evaluated. The mean CS was 100.3 (SD ±44.9), AS was 107.22 (SD ±47.9), IS was 15.3 (SD ±3.7), and the mean readability grade level was 10.4 (SD ±2.5). Only 5 websites had the minimum mandatory basic accessibility. Commercial sites and sites with quality labels had significantly more accessibility violations.
Internet gastric cancer information is overtly commercial, generally incomplete, and poorly accessible.
患者越来越多地在互联网上查询胃癌信息。然而，这些信息的质量是值得怀疑的。我们评估了胃癌网站的准确性、完整性、可及性、可靠性和可读性。
使用通用搜索引擎搜索“胃癌”或“胃癌”等术语。使用预先制定的质量评估工具（QAIs）评估网站的完整性（CS）和准确性（AS），使用完整性评分（IS）评估可靠性，使用 Flesch-Kincaid（FK）等级评估可读性，使用自动化可访问性评估工具评估可及性。注意网站赞助商和质量标签的存在。
评估了 51 个网站。CS 的平均值为 100.3（SD ±44.9），AS 为 107.22（SD ±47.9），IS 为 15.3（SD ±3.7），平均可读性等级为 10.4（SD ±2.5）。只有 5 个网站具有最低强制性基本可访问性。商业网站和带有质量标签的网站存在更多的可访问性违规行为。
互联网胃癌信息过于商业化，通常不完整，且难以获取。
