Death or survival with major morbidity in VLBW infants born at Brazilian neonatal research network centers

AbstractObjective: To analyze unfavorable outcomes at hospital discharge of preterm infants born at Brazilian public university centers.Methods: Prospective cohort of 2646 inborn infants with gestational age 23–33 weeks and birth weight 400–1499 g, without malformations, born at 20 centers in 2012–2013. Unfavorable outcome was defined as in-hospital death or survival at hospital discharge with ≥1 major morbidities: bronchopulmonary dysplasia (BPD) at 36 corrected weeks, intraventricular hemorrhage (IVH) grades 3–4, periventricular leukomalacia (PVL) or surgically treated retinopathy of prematurity (ROP).Results: Among 2646 infants, 1390 (53%) either died or survived with major morbidities: 793 (30%) died; 497 (19%) had BPD; 358 (13%) had IVH 3–4 or PVL; and 84 (3%) had ROP. Logistic regression adjusted by center showed association of unfavorable outcome with: antenatal steroids (OR 0.70; 95%CI 0.55–0.88), C-section (0.72; 0.58–0.90), gestational age <30 (4.00; 3.16–5.07), being male (1.44; 1.19–1.75), sma...
