Quality and Readability of Spanish-Language Online Information for Aortic Aneurysm and Its Endovascular Treatment

Aortic aneurysms represent a chronic degenerative disease with life-threatening implications. In order for patients to comprehend health related information, it must be written at a level that can be readily understood.

In January 2023, we searched "aneurisma aorta" and "endoprótesis aorta" terms on Google, Yahoo and Microsoft/Bing. The 31th websites provided by each search engine were analyzed. Four readability measures were used to evaluate websites regarding aortic aneurysm and their endovascular treatment in Spanish language: Flesch Index, Flesch-Szigriszt Index, Fernández-Huerta Index and grading Inflesz scale. The quality on information was evaluated by the HONcode seal, the DISCERN instrument and the JAMA benchmark criteria.

180 websites containing the terms "aneurisma aorta" and "endoprótesis aorta" were analyzed. Among the websites retrieved, the mean Flesh index score (53.12 ± 6.09 and 47.48 ± 7.12, respectively; P = .019), the Flesch-Szigriszt index (56.39 ± 5.72 and 48.10 ± 8.33; P = .000), and the Fernández Huerta index (61.30 ± 5.59 and 53.19 ± 8.21; P = .000), corresponding to a "somewhat difficult" readability level. In addition, the Inflesz scale (2.62 ± .59 and 2.07 ± .61; P = .000) reported a "somewhat difficult" readability, higher for the websites regarding aortic aneurysm. The HONcode seal was only presented in websites regarding aortic aneurysm (16.7%), whereas none of the websites relating to aortic endoprostheses presented it (0%) (P = .000). Websites that presented the HONcode seal obtained higher DISCERN score (P = .000, 95% CI = 6.42-16.84) and JAMA score (P = .000, 95% CI = 3.44-11.32).

Internet information on aortic aneurysms and aortic endoprostheses is too difficult to read for the general Spanish-speaking population and is lacking in quality.
