Introduction and objectives

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.

Methods

In November 2010, information from the Internet was compiled by entering the terms 鈥?em>aneurisma aorta鈥?(aortic aneurysm) and 鈥?em>endopr贸tesis aorta鈥?(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.

Results

The results for Web pages containing the terms aneurisma aorta and endopr贸tesis aorta indicated that the readability of the material retrieved was 鈥渟omewhat difficult鈥?based on the Flesch index within Microsoft Word (48.3 卤 11.42 and 50.11 卤 9.33, respectively; P=.87), Flesch-Szigriszt index (52.69 卤 8.86, 49.31 卤 7.24; P=.87), Fern谩ndez-Huerta index (58.05 卤 8.5, 54.44 卤 7.19; P=.82), and Gunning-Fog index (22.03 卤 2.05, 23.86 卤 1.59; P=.83), as well as the Inflesz grading scale (2.39 卤 0.7, 2.08 卤 0.64; P=.28). The LIDA values for accessibility (82.28 卤 14.14, 77.77 卤 12.64; P=.98), usability (72.28 卤 16.67, 72.28 卤 26.61; P=.08), and reliability (46.17卤28.69, 56.38卤16.17; P=.06) and the total score (70.22卤16.85, 72.15卤14.93; P=.52), yielded an evaluation of 鈥渕oderate鈥?

Conclusions

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.
