Evaluating the Readability and Quality of Online Patient Education Materials for Pediatric ACL Tears

Abstract

Background: As the rate of anterior cruciate ligament (ACL) tears increases in children, the internet has become a major source of information and education. In the United States, the average adult reads at about an eighth grade level. The National Institutes of Health recommends that patient education materials do not exceed a sixth-grade reading level. Therefore, the most accessed resources on the internet should be created with this in mind. The purpose of this study is to assess the readability and quality of online patient resources for pediatric ACL tears. Methods: Google was queried using the term “Pediatric ACL Tear” on May 26, 2022. The most popular sites were identified through page one of a Google search. All content was evaluated to assure information was directed toward patients. To determine reading difficulty, the most widely accepted readability tests: Flesch Reading Ease Index, Flesch-Kincaid Grade Level, and Gunning Fog Index were calculated through plain text in Microsoft Word and URL in online readability checker Readable.io. Results: The average grade level for all resources was above the recommended reading level based on both Microsoft Word and Readable.io calculations. Each source exceeded the NIH recommendation by 2.6 grade levels on average (Mean grade level readability was 8.6 ± 1.9). Four of the 6 sites were above the average US reading level, exceeding the eighth grade by an average of 1.5 grade levels. All 6 sites analyzed had a mean DISCERN score of 61.9, meeting the ‘good quality’ criteria. Conclusion: The most readily available online materials for Pediatric ACL tears were of ‘good quality’ but above both the NIH-recommended readability level and the average US adult reading level. With the increasing need for treatment of ACL tears in pediatric and adolescent patients and greater internet accessibility in these populations, it is important to consider the readability of these resources in support of increased health literacy and improved outcomes. Clinical Relevance: It is important for physicians treating young patients with ACL tears to be aware of all sources of information and support, including content shared online as these platforms are increasingly utilized, especially by patients and families of lower socioeconomic status.
