Abstract

Socioeconomic status (SES) affects a range of health outcomes but has not been extensively explored in the single ventricle population. We investigate the impact of community-level deprivation on morbidity and mortality for infants with single ventricle heart disease in the first year of life. Retrospective cohort analysis of infants enrolled in the National Pediatric Cardiology Improvement Collaborative who underwent staged single ventricle palliation examining mortality and length of stay (LOS) using a community-level deprivation index (DI). 974 patients met inclusion criteria. Overall mortality was 20.5%, with 15.7% of deaths occurring between the first and second palliations. After adjusting for clinical risk factors, the DI was associated with death (log relative hazard [Formula: see text] = 8.92, p = 0.030) and death or transplant (log relative hazard [Formula: see text] = 8.62, p = 0.035) in a non-linear fashion, impacting those near the mean DI. Deprivation was associated with LOS following the first surgical palliation (S1P) (p = 0.031) and overall hospitalization during the first year of life (p = 0.018). For every 0.1 increase in the DI, LOS following S1P increased by 3.35 days (95% confidence interval 0.31-6.38) and total hospitalized days by 5.08 days (95% CI 0.88-9.27). Community deprivation is associated with mortality and LOS for patients with single ventricle congenital heart disease. While patients near the mean DI had a higher hazard of one year mortality compared to those at the extremes of the DI, LOS and DI were linearly associated, demonstrating the complex nature of SES factors.
