Insights
Patient education materials on pediatric septic arthritis often exceed recommended readability levels, hindering access to crucial orthopedic emergency information for families. Improving these materials is vital for health equity.
Area of Science:
- Orthopedics
- Pediatric Medicine
- Health Communication
Background:
- Pediatric septic arthritis is a critical orthopedic emergency requiring prompt diagnosis and treatment.
- Accessible patient education materials (PEMs) are essential for families seeking information on this condition.
- Existing orthopedic PEMs often present readability challenges, exceeding recommended grade levels.
Purpose of the Study:
- To evaluate the readability of online PEMs for pediatric septic arthritis.
- To assess the alignment of these materials with established readability guidelines.
- To analyze content from top-ranked US pediatric orthopedic hospitals.
Main Methods:
- Searched websites of the top 25 US pediatric orthopedic hospitals for relevant PEMs.
- Analyzed 12 qualifying PEMs using eight standardized readability metrics.
- Correlated Flesch-Kincaid Grade Level (FKGL) with hospital ranking.
Main Results:
- The average readability was 10.6 grade level, significantly above the recommended sixth-grade level.
- None of the PEMs met the recommended readability standards.
- Seven PEMs were written above the eighth-grade reading level, while five (41.7%) were at or below it, often using third-party content.
Conclusions:
- A significant portion of top pediatric orthopedic hospitals do not provide accessible PEMs for septic arthritis.
- Available online information on pediatric septic arthritis frequently exceeds recommended readability levels.
- Implementing plain language, external reviews, or AI-assisted editing can improve material accessibility and health equity.
Background:
Pediatric septic arthritis is a time-sensitive orthopedic emergency requiring prompt recognition and treatment to avoid serious morbidity. Families often seek information online, yet prior studies show patient education materials (PEMs) in orthopedics frequently exceed recommended readability standards (≤6th-grade level).
Purpose:
This study aims to evaluate the readability of online PEMs on pediatric septic arthritis from top-ranked US pediatric orthopedic hospitals and assess alignment with readability guidelines.
Methods:
In July 2025, websites of the top 25 US pediatric orthopedic hospitals were searched for PEMs on "septic arthritis" in children. Hospitals were included if they hosted a dedicated PEM ≥100 words. Text was extracted, cleaned of non-narrative elements, and analyzed with eight readability metrics: Flesch-Kincaid Grade Level (FKGL), Gunning Fog Index, Simple Measure of Gobbledygook (SMOG), Coleman-Liau Index, Automated Readability Index (ARI), Flesch Reading Ease Score (FRES), Ford, Caylor, Sticht (FORCAST) formula, and Dale-Chall Readability Score. Descriptive statistics were summarized, and FKGL was correlated with hospital rank using Spearman's test.
Results:
Of 25 hospitals, 12 (48%) hosted qualifying PEMs. The mean readability was grade 10.6, above the recommended sixth-grade level; none achieved ≤6. Seven institutional PEMs were written at an average reading level significantly above the eighth-grade reading level (p < 0.01). Five PEMs (41.7%) were written at or below the eighth-grade level, largely from identical third-party content. Mean FRES was 51, reflecting "somewhat challenging" readability. Higher-ranked hospitals trended toward worse FKGL scores, but correlation was nonsignificant (ρ = -0.32; p = 0.31).
Conclusions:
Nearly half of the top hospitals lacked PEMs on pediatric septic arthritis, and available content largely exceeded recommended readability. Adoption of plain-language guidelines, external audits, or artificial intelligence (AI)-assisted editing may enhance accessibility and equity.
