背景资料。消费者越来越多地在互联网上咨询乳腺癌信息。考虑到准确性，多个组织制定了在线内容的质量标准。然而，这些工具的有效性尚不清楚。作者确定了现有的质量标准是否可以在线识别不准确的乳腺癌信息。方法：作者通过在5个流行的网络搜索引擎上使用15个与乳腺癌相关的查询识别出343个独特的网页。每个页面都被评估了15个质量标准和3个网站特征，链接类型(赞助或非赞助)，用于查找页面的搜索引擎，以及域名扩展。两名临床医生审查员独立评估了准确性和所涵盖的主题。然后，作者确定质量标准、网站特征和主题是否与不准确陈述的存在相关。结果作者在18个网页上发现41个不准确陈述(5.2%)。没有质量标准或网站特征，无论是单独的还是组合的，都不能可靠地识别不准确的信息。网站满足的质量标准总数在存在不准确的情况下只占变异性的一小部分(双序点r=-0.128；df=341p=.018；r(2)=0.016)。然而，与没有补充和替代医学(CAM)信息的网页相比，包含补充和替代医学(CAM)信息的网页更有可能包含不准确的信息(优势比[OR]，15.6；P
BACKGROUND. Consumers increasingly consult the Internet for breast cancer information. Concerned about accuracy, multiple organizations developed quality criteria for online content. However, the effectiveness of these tools is unknown. The authors determined whether existing quality criteria can identify inaccurate breast cancer information online.METHODS. The authors identified 343 unique webpages by using 15 breast cancer-related queries on 5 popular web search-engines. Each page was assessed for 15 quality criteria and 3 website characteristics, link type (sponsored or not), search engine used to find the page, and domain extension. Two clinician-reviewers independently assessed accuracy and topics covered. The authors then determined whether quality criteria, website characteristics, and topics were associated with the presence of inaccurate statements.RESULTS. The authors found 41 inaccurate statements on 18 webpages (5.2%). No quality criteria or website characteristic, singly or in combination, reliably identified inaccurate information. The total number of quality criteria met by a website accounted for a small fraction of the variability in the presence of inaccuracies (point biserial r = -0.128; df = 341; P =.018; r(2) = 0.016). However, webpages containing information on complementary and alternative medicine (CAM) were significantly more likely to contain inaccuracies compared with pages without CAM information (odds ratio [OR], 15.6; P
