Socioeconomic and geographic disparities in pediatric scoliosis surgery

To compare the population of pediatric patients undergoing surgery for scoliosis in California by gender, race, and ethnicity and identify any underlying differences in social determinants of health as measured by the child opportunity index (COI), social deprivation index (SDI), and insurance category among them.

This project extracted demographic reports including patient sex, race, zip code, insurance type, and associated diagnosis and procedure codes from the Office of Statewide Health Planning and Development (OSHPD). These data were combined with COI and SDI data, which further describe the socioeconomic environment of each patient. Census data were referenced to compare the population of patients receiving scoliosis procedures to the general population by race and ethnicity. Chi-square tests were performed for categorical data. Independent t-test and one-way analysis of variance (ANOVA) were performed for continuous data, with significance set at 0.05.

Unfavorable SDI and COI scores were observed among males, Hispanics, and Black patients, and these patients were more likely to be covered by Medi-Cal. Length of stay was significantly higher among males and Medi-Cal recipients.

The data demonstrate significant differences in social determinants of health as measured by race, ethnicity, gender, insurance type, COI, and SDI among patients ≤ 20 years undergoing surgery for idiopathic scoliosis in California. The noted differences in socioeconomic status (SES) and insurance are known and/or expected to have an impact on access to quality health care, exposing a need for future studies to determine whether COI and SDI influence patient-reported outcomes after scoliosis surgery.
