Society of University SurgeonsReadability of online patient resources for the operative treatment of breast cancer

BackgroundIncreasing use of Internet resources for health information is important in promoting patient involvement in medical care and decision-making. The National Institutes of Health and American Medical Association have recommended that patient health information should be written at a sixth-grade reading level. This study evaluates the readability of the most commonly used Internet resources for the operative treatment of breast cancer in the context of average American literacy.MethodsThe top 10 websites for “breast cancer surgery” based on public Internet search engines were identified. Patient-directed content was downloaded from all relevant articles on these sites. A total of 104 articles were assessed with the use of 10 established readability analyses. Average readability scores were analyzed for all articles as well as by website.ResultsThe overall average reading level across all sites was 12.9; this was similar between tests (Coleman-Liau 12.6, Flesch Kincaid 12.3, FORCAST 11.2, Fry 14, Gunning Fog 14.4, New Dale-Chall 12.4, New Fog 11, Raygor 14, and Simple Measure of Gobbledygook 14.3). Comparing readability by website showed disparity in average reading level from 11.2 to 16.5.ConclusionOnline patient resources for breast cancer surgery exceed recommended reading levels and are too difficult to be understood by a large portion of the United States population.
