RESUMO
INTRODUCTION: Congenital diaphragmatic hernia (CDH) is readily prenatally diagnosed and associated with significant perinatal morbidity and mortality. Delivery at facilities with adequate resources for neonatal resuscitation, such as Children's Surgery Verification (CSV) centers, is recommended; however, disparities have been clinically noted. We aimed to characterize locoregional care of CDH and the impact of race and ethnicity. METHODS: We conducted a population-based study using the Texas Inpatient Public Use Data File to identify infants <1 y-old with CDH based on international classification of diseases 9/10 codes (2013-2021). Only initial birth admissions in the Houston region were included. Data was analyzed using descriptive statistics and chi-squared analysis. RESULTS: We identified 257 newborns with CDH. While births were noted across 29 facilities, the majority were at the 2 CSV centers in Houston. There was no significant difference in illness severity, prematurity or insurance status by race. Black and 'other' patients were less likely to deliver at CSV facilities (Black 32% versus 'Other' 48% versus White 70% versus Asian 81%; P < 0.01), receive ECMO (Black 6% versus 'Other' 5% versus White 19% versus Asian 29%; P < 0.01) or undergo a CDH repair (Black 26% versus 'Other' 33% versus White 51% versus Asian 71%; P < 0.01) on their index admission and had lower average daily costs (Black $10,292 [$3219-25,021] versus 'Other' $9106 [$3617-15,672] versus White $12,906 [$9038-18,550] versus Asian $12,896 [$7469-23,817]; P < 0.05). Additionally, black and 'other' patients were more likely to be transferred (Black 23% versus 'Other' 28% versus White 12% versus Asian 14%; P < 0.05). None of the patients born at CSV centers transferred. CONCLUSIONS: Most Houston-born patients deliver at high-resource centers; however, Black and 'other' patients are less likely to deliver at CSV centers and more likely to require transfer during the critical neonatal period. This suggests a vulnerable population which may benefit from targeted intervention to improve prenatal care and delivery planning.
RESUMO
INTRODUCTION: Congenital diaphragmatic hernia (CDH) is a life-threatening, prenatally diagnosed congenital anomaly. We aim to characterize care and outcomes of infants with CDH in Texas and the impact of treating facilities volume of care. METHODS: Retrospective cohort study using a state-wide Hospital Inpatient Discharge Public Use Data File was conducted (2013-2021). Neonates and infants <1 year of age were included using CDH ICD-9/ICD-10 codes. Neonates transferred to an outside hospital were excluded to avoid double-counting. Descriptive statistics, chi-square and logistic regression analysis were performed. RESULTS: Of 1314 CDH patient encounters identified, 728 (55%) occurred at 5 higher volume centers (HVC, >75 cases), 326 (25%) at 9 mid-volume centers (MVC, 20-75 cases) and 268 (20%) at 79 low volume centers (LVC, <20 cases). HVC had lower mortality rates (18%, MVC 22% vs LVC 27%; p = 0.011) despite treating sicker patients (extreme illness severity: HVC 71%, MVC 62% vs LVC 50%; p < 0.001) with longer length-of-stay (p < 0.001). Extracorporeal membrane oxygenation was used in 136 (10%) and provided primarily at HVC. LVC treated proportionately more non-white Hispanic patients (p < 0.001) and patients from counties along the Mexican border (p < 0.001). The predicted probability of mortality in CDH patients decreases with higher treatment facility CDH case volume, with a 0.5% decrease in the odds of mortality for every additional CDH case treated (p < 0.001). CONCLUSIONS: Patients treated in HVC have significantly lower mortality despite increased severity. Our data suggest minority populations may be disproportionately treated at LVC associated with worse outcomes. TYPE OF STUDY: Retrospective Prognosis Study. LEVEL OF EVIDENCE: Level II.
