脑动静脉畸形(AVM)是由动脉和静脉之间的不正确连接造成的血管畸形,最常见于大脑和脊髓。管理复杂且依赖患者;必须进一步了解患者教育活动。互联网接入变得越来越普遍,允许患者在线使用大型医疗信息数据库。使用谷歌趋势(GT)(谷歌有限责任公司,山景,CA,美国),随着时间的推移,人们可以看到公众对特定主题的兴趣。Further,当显示大量搜索结果时,患者可能无法确定产量最高的资源,客观衡量信息质量和可读性势在必行。方法对遗传性出血性毛细血管扩张症进行GT分析。脑动脉瘤,\"和\"动静脉畸形\"。将这些相对搜索量(RSV)与2017年至2019年美国AVM诊断量进行相关性比较。这些RSV还与2017年至2019年美国因脑出血导致的年度死亡进行了比较。对“脑动静脉畸形”进行了一次搜索。由于大多数在线查找健康信息的用户仅使用第一页来源,质量和可读性分析仅限于Google搜索结果的第一页。使用了五个质量工具和六个可读性公式。结果Pearson相关系数显示,2017-2019年美国AVMRSV与年人均AVM死亡呈正相关(R2=0.932)。AVM年诊断量和AVMRSV也显示出强正相关(R2=0.998)。在2017年至2019年期间,遗传性出血性毛细血管扩张症和脑动脉瘤的RSV与相应的年度诊断之间存在很强的正相关关系(R2=0.982,R2=0.709)。单向方差分析,对于美国2004年至2021年的AVMRSV和2004年至2019年的人均死亡人数,没有显示特定月的统计学显著重复模式(所有p>0.483)。DISCERN工具有四个符合“差”标准的网站和五个符合“好”标准的网站。“该工具的平均分数是好的”。“《美国医学会杂志》(JAMA)的基准得分平均非常低,四个网站实现了零点。货币差异很大,相关性,权威,准确度,和目的(CRAAP)分数,表明结果之间的网页可靠性水平不一致。患者教育材料评估工具(PEMAT)可理解性(86.6%)的得分远高于PEMAT可操作性(54.6%)。没有平均可读性得分等于或低于美国医学会(AMA)推荐的六年级阅读水平。结论这些GT相关性可能是由于具有新诊断的患者和家庭在线研究相同条件。季节性结果反映出先前没有研究检测到AVM诊断或表现的季节性。质量研究表明,网站道德存在很大差异,治疗信息质量,网站/作者资格,以及关于AVM的可操作的后续步骤。总的来说,这项研究表明,患者通常试图获取有关这些颅内疾病的信息,但是现有的信息,特别是关于AVM,通常不可靠,理解它们所需的阅读水平太高。
Introduction Brain arteriovenous malformations (AVMs) are vascular deformities created by improper connections between arteries and veins, most commonly in the brain and spinal cord. The management is complex and patient-dependent; further understanding of patient education activities is imperative. Internet access has become more ubiquitous, allowing patients to utilize a large database of medical information online. Using Google Trends (GT) (Google LLC, Mountain View, CA, USA), one can see the public interest in a particular topic over time. Further, when presented with numerous search results, patients may not be able to identify the highest-yielding resources, making objective measures of information quality and readability imperative. Methods A GT analysis was conducted for \"hereditary hemorrhagic telangiectasia,\" \"cerebral aneurysm,\" and \"arteriovenous malformation\". These relative search volumes (RSV) were compared with the 2017 to 2019 annual USA AVM diagnosis quantity for correlation. These RSVs were also compared with the 2017 to 2019 annual USA deaths due to cerebral hemorrhagic conditions. One search was conducted for \"brain arteriovenous malformation\". Since most users looking for health information online use only the first page of sources, the quality and readability analyses were limited to the first page of results on Google search. Five quality tools and six readability formulas were used. Results Pearson\'s correlation coefficients showed positive correlations between USA AVM RSVs and annual AVM deaths per capita from 2017 to 2019 (R2=0.932). The AVM annual diagnosis quantity and AVM RSVs showed a strong positive correlation as well (R2=0.998). Hereditary hemorrhagic telangiectasia and cerebral aneurysms had strong positive correlations between their RSVs and their corresponding annual diagnoses in the 2017 to 2019 time period (R2=0.982, R2=0.709). One-way ANOVA, for USA\'s 2004 to 2021 AVM RSVs and 2004 to 2019 deaths per capita, displayed no month-specific statistically significant repeating pattern (all p>0.483). The DISCERN tool had four websites that qualified as \"poor\" and five as \"good.\" The average score for the tool was \"good.\" The Journal of the American Medical Association (JAMA) benchmark scores were very low on average, as four websites achieved zero points. There was a wide variance in the currency, relevance, authority, accuracy, and purpose (CRAAP) scores, indicating an inconsistent level of webpage reliability across results. The patient education materials assessment tool (PEMAT) understandability (86.6%) showed much higher scores than the PEMAT actionability (54.6%). No readability score averaged at or below the American Medical Association (AMA)-recommended sixth-grade reading level. Conclusion These GT correlations may be due to patients and families with new diagnoses researching those same conditions online. The seasonality results reflect that no prior research has detected seasonality for AVM diagnosis or presentation. The quality study showed a wide variance in website ethics, treatment information quality, website/author qualifications, and actionable next steps regarding AVMs. Overall, this study showed that patients are routinely attempting to access information regarding these intracranial conditions, but the information available, specifically regarding AVMs, is not routinely reliable and the reading level required to understand them is too high.
