Systematic review finds online cleft care materials exceed recommended readability levels
This systematic review and meta-analysis evaluated online patient education materials for cleft care. The authors analyzed nine studies to determine if the text complexity aligns with recommended readability standards. The scope included materials for cleft lip and cleft palate care found in PubMed, Scopus, and Embase databases.
The pooled results indicate that the Flesch-Kincaid Grade Level was 9.48 (95% CI: 8.51-10.45). The Flesch Reading Ease score averaged 52.98 (95% CI: 42.62-63.34). The SMOG Index yielded a result of 9.27 (95% CI: 5.97-12.57). The Gunning Fog Index result was 9.94 (95% CI: 8.90-10.98). All these metrics exceed recommendations.
Heterogeneity analysis showed an I² value of 0%. The authors noted that artificial intelligence tools lacked usability and comprehension testing. The review highlights that online patient education materials for cleft care are consistently written at reading levels too complex for the average caregiver.
The study did not report adverse events or discontinuations. Funding or conflicts were not reported. The authors caution against inferring causality from pooled readability estimates or assuming clinical outcomes from readability metrics. Improved readability and accessibility are needed for this patient population.
