The ubiquity of the Internet is changing the way people obtain their health information. Although there is an abundance of heart failure information online, the quality and health literacy demand of these information are still unknown.
The purpose of this study is to evaluate the quality and health literacy demand (readability, understandability, and actionability) of the heart failure information found online.
Google, Yahoo, Bing, Ask.com, and DuckDuckGo were searched for relevant heart failure Web sites. Two independent raters then assessed the quality and health literacy demand of the included Web sites. The quality of the heart failure information was assessed using the DISCERN instrument. Readability was assessed using 7 established readability tests. Finally, understandability and actionability were assessed using the Patient Education Materials Assessment Tool for Print Materials.
A total of 46 Web sites were included in this analysis. The overall mean quality rating was 46.0 ± 8.9 and the mean readability score was 12.6 grade reading level. The overall mean understandability score was 56.3% ± 16.2%. Finally, the overall mean actionability score was 34.7% ± 28.7%.
The heart failure information found online was of fair quality but required a relatively high health literacy level. Web content authors need to consider not just the quality but also the health literacy demand of the information found in their Web sites. This is especially important considering that low health literacy is likely prevalent among the usual audience.
互联网的普及正在改变人们获取健康信息的方式。尽管网上有大量关于心力衰竭的信息，但这些信息的质量以及对健康素养的要求仍不明确。
本研究旨在评估网上获取的心力衰竭信息的质量以及对健康素养的要求（可读性、可理解性和可操作性）。
在谷歌、雅虎、必应、Ask.com和DuckDuckGo上搜索相关的心力衰竭网站。然后由两名独立的评估者评估纳入网站的质量和对健康素养的要求。使用DISCERN工具评估心力衰竭信息的质量。使用7种既定的可读性测试评估可读性。最后，使用印刷材料患者教育材料评估工具评估可理解性和可操作性。
本分析共纳入46个网站。总体平均质量评分为46.0±8.9，平均可读性得分为12.6年级阅读水平。总体平均可理解性得分为56.3%±16.2%。最后，总体平均可操作性得分为34.7%±28.7%。
网上找到的心力衰竭信息质量尚可，但需要相对较高的健康素养水平。网站内容作者不仅要考虑信息的质量，还要考虑其网站上信息对健康素养的要求。鉴于普通受众中低健康素养可能很普遍，这一点尤为重要。
