Craniosynostosis: Are Online Resources Readable?

Abstract

Objective: This study aims to analyze the readability of online craniosynostosis materials from the perspective of a caregiver, and to assess if readability levels conform to recommendations by the American Medical Association (AMA) and National Institutes of Health (NIH).

Design: This is a cross-sectional investigation in which an internet search was conducted simulating the search terms of a caregiver of a patient with craniosynostosis. The first three pages of resulting records were calculated for comprehension ease using validated readability indices. Records were also classified by author type, including hospital system, national health organization, academic journal, and other.

Main outcome measures: Flesch-Kincaid Reading Grade Level, Gunning fog Index, SMOG Index, and Coleman Liau Index.

Results: Thirty records were identified for which the mean readability level was 12.8 ± 2.6 grade levels (range, 7.6-15.9). There were no significant differences in mean readability across readability indices or author type. None of the thirty records met levels recommended by the AMA or NIH and were 6.8 grade levels above these guidelines on average.

Conclusions: Online material pertaining to craniosynostosis is written, on average, at the reading level of a first-year undergraduate student. The AMA and NIH recommend that articles be written at approximately a sixth-grade reading level to promote comprehension. Therefore, there is significant room for improvement of current online materials. Authors should consider consulting publicly available guides in preparing future resources.
