Abstract
BACKGROUND: Socioeconomic and racial (SER) disparities among patients with congenital heart disease (CHD) may limit access to high-quality care. We characterized the national SER landscape and its relationship to early outcomes and identified interactions among determinants mitigating adverse outcome. METHODS: The Pediatric Health Information System (PHIS) database was queried for patients (age <26 years) with CHD between 2016 and 2018. International Classification of Diseases, 10th Revision, codes were mapped to diagnostic categories for complexity adjustment. Correlational and hierarchical regression analyses identified risk factors and characterized interactions. RESULTS: We identified 166,599 unique admissions from 52 hospitals, with 58,395 having interventions. Median age was 0 years (interquartile range [IQR], 4 years). Race/ethnicity was predominantly White (59%), Hispanic (20%), and Black (16%). Median neighborhood household income (NHI) was $41,082 and varied among hospitals. Patient NHI had a parabolic relationship with mortality, with both higher and lower values having increased risk. Black patients had significantly higher death, and this relationship was potentiated by lower NHI and complexity. Hospital length of stay was longer among Black neonates (median, 51 days; IQR, 93 days) compared with neonates of other ethnic groups (median, 32 days; IQR, 71 days; P < .0001. Care pathways, including permanent feeding tubes, were also more prevalent among Black neonates (17.8%) compared with White neonates (15%; P = .02). CONCLUSIONS: Interactions among SER disparities modify CHD outcomes. Specific hospitals have more SER fragile patients but may have developed care pathways that prolong length of stay to mitigate risk among Black neonates. Adverse outcomes among SER-disadvantaged patients are magnified in complex CHD, suggesting tangible benefits to targeted resource allocation and population health initiatives.
