(A) Predicted maternal outcomes for mothers admitted to high-, average-, and low-performance hospitals based on either the severe maternal morbidity (SMM) metric or the composite metric. (B) Predicted newborn outcomes for mothers admitted to high-, average-, and low-performance hospitals based on either the severe newborn morbidity (SNM) metric or the composite metric. All P values were less than 0.05 for comparisons to average performance hospitals. Adjusted rates of severe maternal morbidity (A) are adjusted for age, race, ethnicity, education, insurance, prenatal care, parity at delivery, gestational age, prior cesarean delivery, multiple gestation, presentation, hypertensive disease, placental abnormalities, premature rupture of membranes, and comorbidities. Adjusted rates of severe newborn morbidity (B) are adjusted for race, ethnicity, education, insurance, prenatal care, weight at delivery, parity at delivery, gestational age, intrauterine growth restriction, prior cesarean delivery, multiple gestation, presentation, hypertensive disease, placental abnormality, premature rupture of membranes, precipitous labor, and comorbidities.
