Sociodemographic Factors Associated with Delayed Presentation in Craniosynostosis Surgery at a Tertiary Children’s Hospital

Abstract

Background: Craniosynostosis is a common diagnosis requiring early referral to a pediatric plastic surgeon; however, disparities in healthcare may influence presentation timing and affect treatment options and outcomes. This study aimed to explore sociodemographic factors contributing to delay in craniosynostosis surgical consultation. Methods: A retrospective cohort study of 694 California-based craniosynostosis patients at a tertiary children’s hospital was performed from 2006 to 2023. State-specific Area Deprivation Index (ADI) and distance to the hospital were calculated using ZIP codes. Multivariate linear and logistic regressions considered race, insurance type, syndromic status, suture type, and ZIP code-based socioeconomic factors. Results: Median age of presentation was 4.5 [interquartile range: 2.6–7.6] months with racial/ethnic breakdown of Hispanic/Latinx (41.2%), White (23.6%), Asian (3.7%), Black/African American (2.0%), or other/unreported (29.5%) with 58.4% having public insurance and an average distance to the hospital of 48.3 km. Median ADI was 5.4 [interquartile range: 4.0–7.1]. By linear regression, public insurance (P < 0.001) and higher ADI decile (P < 0.001) independently contributed to an older age of presentation. Patients with public insurance (odds ratio 1.90; P = 0.002) were more likely to present after 4 months of age. Conclusions: Patients who had public insurance or resided in more disadvantaged areas presented later for craniosynostosis surgical consultation. Eliminating disparities in these populations ensures more equitable access to surgical options and can improve patient outcomes.
