Readability of Neurosurgical Patient Education Resources by the American Association of Neurological Surgeons

Background: The importance of patient education has become increasingly apparent in recent years. A prominent patient education tool in neurosurgery is the Neurosurgical Conditions and Treatments page provided by the American Association of Neurological Surgeons (AANS). This study aimed to investigate the readability of this resource page as many new articles have been incorporated in the past decade.

Methods: Flesch-Kincaid Grade Level and Flesch-Kincaid Reading Ease scores were calculated for each article. One-way analysis of variance and Scheffé, Tukey-Kramer, Bonferroni, Fisher least significant difference, and Dunnett test post hoc analyses were conducted to determine differences between each category with respect to their mean grade level and reading ease scores.

Results: Overall mean (SD) Flesch-Kincaid Reading Ease score was 40.2 (12.24), and overall mean (SD) Flesch-Kincaid Grade Level score was 7.48 (1.26). Significant differences were found between mean reading ease scores between each categorization by the AANS (P = 0.014). No significant differences were found between mean grade level score for each categorization (analysis of variance, P = 0.154).

Conclusions: As compared to a single previous investigation conducted 10 years ago, the readability of articles has changed modestly, and the reading grade level remains well above the recommendations by the American Medical Association and National Institutes of Health. The 6 new articles introduced in the past decade have demonstrated similar readability, presenting a persistent challenge in the realm of patient education in neurosurgery.
