Readability of Online Patient Educational Materials in Pediatric Orthopaedics: A Systematic Review

As most patients and their families utilize online education materials, ensuring that their readability is at or below the recommended reading level of sixth grade is imperative to enhance informed consent, patient involvement, and shared decision-making. We evaluated and compared the readability of online patient education materials (PEMs) about pediatric orthopaedics for academic-sponsored websites and search-engine result websites.

Following the PRISMA-P guidelines, we performed a systematic review to answer our study question (PROSPERO registration of the study protocol: CRD42022352323, August 8, 2022). PubMed, EBSCOhost, Medline, and Google Scholar electronic databases were utilized to identify all studies evaluating the readability of pediatric orthopaedic online PEMs between January 1, 2000 and September 9, 2022. We included studies with full-text manuscripts in English addressing the readability of pediatric orthopaedic online patient education materials. We excluded general reviews, papers, case reports, duplicate studies between databases, grey literature, and publications in languages other than English. The quality of included studies was assessed using the Joanna Briggs Institute (JBI) tool for cross-sectional studies.

Our initial search yielded 196 candidate publications. Of these, 11 studies met inclusion criteria. These included a total of 893 PEMs assessed for readability between January 2001 to December 2021. The mean JBI score was 7.3±1.1. Each of the seven studies assessing PEMs from academic-sponsored sources reported mean readability scores of at least an eighth-grade level. Among the 5 studies assessing the readability of PEMs accessed through search engines, 3 studies reported ninth-grade reading level whereas the other 2 reported 10th-grade. Academic and search-engine website readability scores remained constant between 2001 and 2021.

Our analysis showed poor readability scores for both academic-sponsored website PEMs and those accessed through search engines. In addition, the readability scores remained constant between 2001 and 2021, indicating that revisions to orthopaedic online PEMs are needed. Supplementation with visuals should be included to educate patients with lower health literacy.
