Clear as Mud: Readability Scores in Cloacal Exstrophy Literature and Its Treatment

This study examines the readability of online medical information regarding cloacal exstrophy (CE). We hypothesize that inappropriate levels of comprehension are required in these resources, leading to poor understanding and confusion amongst caregivers.

The Google and Bing search engines were used to search the terms "cloacal exstrophy" and "cloacal exstrophy treatment". The first 100 results for each were collected. Each webpage was analyzed for readability using four independent validated scoring systems: the Gunning-Fog index (GFI), SMOG grade (Simple Measure of Gobbledygook), Dale-Chall index (DCI), and the Flesch-Kincaid grade (FKG).

Forty-seven unique webpages fit the inclusion criteria. Mean readability scores across all websites were GFI, 14.6; SMOG score, 10.8; DCI, 9.3; and FKG, 11.8, correlating to adjusted grade levels of college sophomore, 11th grade, college, and 11th grade, respectively. There were significant differences across all readability formulas. Non-profit websites were significantly less readable than institutional and commercial webpages (GFI p = 0.012, SMOG p = 0.018, DCI p = 0.021, FKG p = 0.0093).

Caregiver-directed health information regarding CE and its treatment available online is written at the 11th grade reading level or above. Online resources pertaining to CE must be simplified to be effective.
