Abstract
Objective
To describe variation in mortality and morbidity effects of high-level, high-volume delivery hospital between racial/ethnic groups and insurance groups.
Study Design
Retrospective cohort including infants born at 24–32 weeks gestation or birth weights ≤2500 g in California, Missouri, and Pennsylvania between 1995 and 2009 (n = 636,764). Multivariable logistic random-effects models determined differential effects of birth hospital level/volume on mortality and morbidity through an interaction term between delivery hospital level/volume and either maternal race or insurance status.
Result
Compared to non-Hispanic white neonates, odds of complications of prematurity were 14–25% lower for minority infants in all gestational age and birth weight cohorts delivering at high-level, high-volume centers (odds ratio (ORs) 0.75–0.86, p < 0.001–0.005). Effect size was greatest for Hispanic infants. No difference was noted by insurance status.
Conclusions
Neonates of minority racial/ethnic status derive greater morbidity benefits than non-Hispanic white neonates from delivery at hospitals with high-level, high-volume neonatal intensive care units.
