ABSTRACT
Introduction: The internet is an ever-evolving resource to improve healthcare literacy among patients. The nature of the internet can make it difficult to condense educational materials in a manner applicable to a worldwide patient audience. Within the realm of endocrinology, there is lack of a comprehensive analysis regarding these pathologies in addition to education materials related to their medical work-up or management. The aim of this study was to assess contemporary online patient education material in endocrinology and management of care. Methods: Analysis of the readability of 1,500 unique online education materials was performed utilizing seven readability measures: Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level (FKGL), Gunning Fog Index Readability Formula (FOG), Simple Measure of Gobbledygook Index (SMOG), Coleman-Liau Index (CLI), automated readability index (ARI), and Linsear Write Formula (LWF). Results: The average grade level readability scores from six measures (e.g., FKGL, FOG, SMOG, CLI, ARI, LWF) was more than or equal to 11 which corresponds to a reading level at or above the 11th grade. The average FRE between adrenal, diabetes, and thyroid-related education m aterial ranged between "fairly difficult" to "very difficult". Conclusions: The readability of contemporary online endocrine education material did not meet current readability recommendations for appropriate comprehension of the general audience.
