Assessing Readability of Patient Education Materials on Breast Reconstruction by Major US Academic Hospitals as Compared With Nonacademic Sites.

PURPOSE: Women undergoing postmastectomy breast reconstruction face many complex choices. A myriad of online patient education materials exist to assist in decision making. Understanding of these materials, termed health literacy, affects surgical decision making and outcomes. The National Institutes of Health recommends writing patient education materials at a sixth- to seventh-grade reading level. The primary goal of this study was to assess readability of online breast reconstruction materials. METHODS AND MATERIALS: Resources were collected from every academic hospital with a plastic surgery residency program, 97 in total. These data were compared with the top nonacademic Web sites ranked by search engine results, 14 in total. Materials were analyzed using 3 validated readability assessment scales: Coleman-Liau Index, SMOG (Simplified Measure of Gobbledygook) Readability Formula, and Flesch-Kincaid Grade Level. Average readability was analyzed, and results were compared using a 1-way analysis of variance to assess for significance between the different tools and a 2-sided t test to assess for significance between academic and nonacademic readability results.
RESULTS: The mean readability scores across the academic programs were a Coleman-Liau Index of 13.38 (standard Deviation [SD] 2.81, 13th to 14th grade), Flesch-Kincaid Grade Level of 13.04 (SD = 3.9, 13th grade), and SMOG Readability of 13.64 (SD = 2.99, 13th to 14th grade). For the 14 nonacademic sites, results showed a Coleman-Liau Index of 11.93 (SD = 1.14, 12th grade), Flesch-Kincaid of 11.82 (SD = 2.33, 11th to 12th grade), and SMOG Readability of 10.91 (SD = 1.79, 11th grade). One-way analysis of variance demonstrated no significant differences in mean readability scores across the 3 readability tools used (academic F = 2.7804, P = 0.06; nonacademic F = 1.14, P = 0.33). Two-tailed t test results demonstrated that there was statistical significance between readability of the academic in comparison with nonacademic search engine results (t = 2.04, P = 0.04).
CONCLUSIONS: Average readability across all Web sites were much higher than the recommended reading level, at a 13th to 14th grade reading level for academic institutions, and an 11th to 12th grade for nonacademic Web sites. Plastic surgeons may contribute to improving patient understanding and perioperative outcomes through revising patient education materials.
