Low health literacy affects nearly one-third of adults in the United States, and almost 68 million Americans speak a language other than English at home. These barriers to understanding medical information are associated with worse clinical outcomes, higher readmission rates, and increased postoperative complications. Despite longstanding recommendations from the National Institutes of Health (NIH) and American Medical Association (AMA) to write patient educational materials (PEMs) at a fifth- sixth-grade level, many orthopaedic PEMs remain above the eighth-grade level and are not consistently available in patients' preferred languages. This study evaluates whether a trained artificial intelligence (AI) model can improve the readability of the existing pediatric orthopaedic PEMs in English and Spanish languages without sacrificing accuracy or key content.Two ChatGPT-4 models were developed and trained, one in English and one in Spanish, using 51 English and 10 Spanish pediatric orthopaedic PEMs from the American Academy of Orthopaedic Surgeons (AAOS) OrthoInfo website. Models were instructed to rewrite PEMs at a fifth- to sixth-grade reading level, emphasizing anatomy, symptoms, physical examination, and treatment options. Training included multiple feedback rounds until readability targets were met. Readability was assessed using validated indices (Flesch-Kincaid, SMOG (Simplified Measure of Gobbledygook, Coleman-Liau, and Automated Readability Index for English; Fernández Huerta, Szigriszt Pazos, and Crawford for Spanish). Ten AI-enhanced English-language PEMs were reviewed for accuracy by a pediatric orthopaedic surgeon.The AI models significantly improved readability across all measures. In English, the mean grade level decreased from 9.8 to 5.8 (P < .001) and Flesch Reading Ease improved from 56.9 to 76.4 (P < .001). In Spanish, Fernández Huerta scores improved from 81.0 to 100.7 (P < .001), reducing grade level from fifth-sixth to fourth. All the 10 reviewed PEMs were considered clinically ... |
