Health disparities driven by race and ethnicity are pervasive in healthcare and impact all aspects of pediatric care

In congenital diaphragmatic hernia, racial and ethnic disparities affect care from prenatal diagnosis and surveillance through postnatal management

The study cohort included 1,625 CDH patients from the PHIS database from 2015 to 2020, admitted on day of life zero with ICD diagnosis code for CDH and procedure code for repair

Hospital volume was defined as less than 10 CDH cases per year as low volume and 10 or more cases as high volume

Institutional racial and ethnic diversity was defined as the percentage of black and/or Hispanic CDH patients treated at each institution, stratified from less than 20% to greater than 40%

Household incomes of black and Hispanic CDH patients were significantly lower than that for white patients

White and Asian CDH patients had primarily commercial insurance, whereas black and Hispanic patients had largely Medicaid payer status

Black CDH patients were born at significantly lower gestational ages and were more likely to be born preterm compared to white patients

Black CDH patients had lower birth weights and lower Apgar scores compared to white patients

Black CDH patients were cannulated to extracorporeal life support (ECMO) more often than white patients

Black CDH patients were mechanically ventilated for longer and required pulmonary anti-hypertensives for longer compared to white patients

Disease severity differences seen in Black CDH patients were not observed in Hispanic and Asian patients when compared to white patients

Black CDH patients were admitted for significantly longer compared to white patients

Black CDH patients were discharged home less often than white patients

Black CDH patients were more likely to require a tracheostomy at the time of discharge compared to white patients

Black CDH patients had decreased in-hospital survival rates of 79% compared to 88% in white patients

Hispanic and Asian CDH patients had comparable survival rates to white patients at 88% and 92% respectively

Low institutional diversity levels (less than 20%) were associated with decreased survival in white, black, and Hispanic CDH patients

Higher institutional diversity levels (between 31 and 40%) were associated with improved survival for white, black, and Hispanic CDH patients

Institutional diversity effects on survival were not observed in Asian CDH patients

Cox regression analysis controlling for severity, socioeconomic status, and institutional covariants including hospital volume showed white CDH patients had comparable outcomes regardless of institutional diversity

Institutions with greater than 30% racial/ethnic diversity conferred a protective effect against mortality for black CDH patients treated there

Institutions with diversity greater than 20% conferred a protective effect for Hispanic CDH patients

Treating a more racially and ethnically diverse CDH patient population improves outcomes for black and Hispanic patients without negatively impacting white patients
