To evaluate the readability, accessibility, usability, and reliability of information available on the Internet in the Spanish language about aortic aneurysm and its endovascular treatment, and to determine whether this information source provides comprehensible material that will enable patients to participate in decisions regarding their condition.
In November 2010, information from the Internet was compiled by entering the terms "aneurisma aorta" (aortic aneurysm) and "endoprótesis aorta" (aortic endoprosthesis) in the most widely used search engines: Google, Yahoo, and MSN/Bing. The first 30 pages provided by each search engine were analyzed. The Inflesz software was used to calculate the readability of the information retrieved and the LIDA instrument, a validated tool to evaluate the quality of health-related Web sites, was used to assess accessibility, usability, and reliability.
The results for Web pages containing the terms aneurisma aorta and endoprótesis aorta indicated that the readability of the material retrieved was "somewhat difficult" based on the Flesch index within Microsoft Word (48.3 ± 11.42 and 50.11 ± 9.33, respectively; P = .87), Flesch-Szigriszt index (52.69 ± 8.86, 49.31 ± 7.24; P = .87), Fernández-Huerta index (58.05 ± 8.5, 54.44 ± 7.19; P=.82), and Gunning-Fog index (22.03 ± 2.05, 23.86±1.59; P=.83), as well as the Inflesz grading scale (2.39 ± 0.7, 2.08 ± 0.64; P=.28). The LIDA values for accessibility (82.28 ± 14.14, 77.77 ± 12.64; P=.98), usability (72.28 ± 16.67, 72.28 ± 26.61; P=.08), and reliability (46.17 ± 28.69, 56.38 ± 16.17; P=.06) and the total score (70.22 ± 16.85, 72.15 ± 14.93; P=.52), yielded an evaluation of "moderate".
The Internet information on aortic aneurysms and its endovascular treatment with aortic endoprostheses was deficient with regard to accessibility, usability, and reliability, and had the added difficultly of complicated readability. Our results suggest that readability indexes should be incorporated in the creation and improvement of Web sites providing medical information related to cardiovascular disease.
评估西班牙语互联网上有关主动脉瘤及其血管内治疗的信息的可读性、可获取性、可用性和可靠性，并确定该信息源是否提供能使患者参与自身病情决策的易懂材料。
2010年11月，通过在最常用的搜索引擎谷歌、雅虎和MSN/必应中输入术语“aneurisma aorta”（主动脉瘤）和“endoprótesis aorta”（主动脉内假体）来收集互联网信息。分析每个搜索引擎提供的前30个网页。使用Inflesz软件计算检索到的信息的可读性，并使用LIDA工具（一种经过验证的评估健康相关网站质量的工具）来评估可获取性、可用性和可靠性。
包含术语aneurisma aorta和endoprótesis aorta的网页结果表明，根据Microsoft Word中的弗莱施指数（分别为48.3±11.42和50.11±9.33；P = 0.87）、弗莱施 - 齐格里斯zt指数（52.69±8.86，49.31±7.24；P = 0.87）、费尔南德斯 - 韦尔塔指数（58.05±8.5，54.44±7.19；P = 0.82）和冈宁 - 福格指数（22.03±2.05，23.86±1.59；P = 0.83）以及Inflesz分级量表（2.39±0.7，2.08±0.64；P = 0.28），检索到的材料的可读性“有点困难”。可获取性的LIDA值（82.28±14.14，77.77±12.64；P = 0.98）、可用性（72.28±16.67，72.28±26.61；P = 0.08）和可靠性（46.17±28.69，56.38±16.17；P = 0.06）以及总分（70.22±16.85，72.15±14.93；P = 0.52）得出“中等”评价。
互联网上有关主动脉瘤及其主动脉内假体血管内治疗的信息在可获取性、可用性和可靠性方面存在不足，且具有复杂可读性的额外困难。我们的结果表明，在创建和改进提供与心血管疾病相关医学信息的网站时应纳入可读性指标。
