Socioeconomic Factors Impact the Timing of Surgical Repair for Craniosynostosis - A Regional and National Assessment.

INTRODUCTION

Timing of repair for patients with craniosynostosis are usually categorized into early "minimally invasive" surgeries such as strip craniotomy (SC), whereas those presenting later undergoing traditional cranial vault remolding (CVR). The impact that sociodemographic and socioeconomic disparities have on time to presentation for craniosynostosis and treatment is unknown. Herein, we examined sociodemographic and socioeconomic factors among a heterogenous patient population at a single institution who underwent craniosynostosis repair and compared this cohort to a national database.

METHODS

A retrospective review of patients at UTHealth who underwent craniosynostosis repair from 2016 to 2020 was performed. The patients were divided into cohorts based on type of operation: SC or cranial vault remolding. The Kid inpatient Database (KiD) database was used to assess sociodemographic factors in relation to craniosynostosis. Univariate and multivariate logistic regression were used to determine significant predictors and differences.

RESULTS

Single Institution (Regional): Compared with nonHispanic white (NHW) patients, Hispanic (OR 0.11), and NonHispanic Black (NHB) (OR 0.14) had lower odds of undergoing SC. Compared to those on private insurance, patients on Medicaid (OR 0.36) had lower odds of undergoing SC. Using zip code median income levels, patients with a higher median income level had slightly higher odds of undergoing SC compared to patients with a lower median income (OR 1.000025).

KIDS NATIONAL

Compared with non-Hispanic white patients, NHB (OR 0.32) and Asian (OR 0.47) patients had lower odds of undergoing repair before the age of 1. Compared to patients with private insurance, those with Medicaid (OR 0.67) and self-pay (OR 0.58) had lower odds of undergoing repair before the age of 1. Patients in the lowest income quartile (OR 0.68) and second lowest income quartile (OR 0.71) had lower odds of undergoing repair before the age of 1 compared to the highest quartile.

CONCLUSIONS

Our findings indicate that sociodemographic and socioeconomic factors may play a role in diagnosis of craniosynostosis and access to care. Patients of NHB and Hispanic race, lower income quartiles by zip code, and those that use public insurance are less likely to undergo early repair, both nationally and at our institution. Further research is needed to delineate the casualty of this disparity in presentation and timing of surgery.
