A three-year cohort of extremely low-birthweight (ELBW, less than 1000g) survivors born between 1st January 1979 and 31st December 1981 were followed prospectively at one, two and five years of age, corrected for preterm birth. 57 of 110 infants survived, and 53 children were still alive at five years. The diagnoses of cerebral palsy, blindness, deafness(More)
OBJECTIVE Not many large studies have reported the true impact of lower-grade intraventricular hemorrhages in preterm infants. We studied the neurodevelopmental outcomes of extremely preterm infants in relation to the severity of intraventricular hemorrhage. METHODS A regional cohort study of infants born at 23 to 28 weeks' gestation and admitted to a(More)
BACKGROUND Despite widespread use of neonatal hospital discharge data, there are few published reports on the accuracy of population health data with neonatal diagnostic or procedure codes. The aim of this study was to assess the accuracy of using routinely collected hospital discharge data in identifying neonatal morbidity during the birth admission(More)
Twenty-four (6%) of 375 infants with birthweights less than or equal to 1500g developed bronchopulmonary dysplasia (BPD); 16 (15%) of 107 in those less than or equal to 100g and 8 (3%) of 268 in those greater than 1000g. The incidence was 10% in those who required assisted ventilation. Perinatal asphyxia, significant respiratory distress, pulmonary(More)
Perinatal factors associated with death or disability at 2 years were identified in an inborn cohort of 196 live births with a birth weight of 500-999 g. Antepartum haemorrhage, multiple pregnancy, breech presentation, perinatal asphyxia, hypothermia on admission, hyaline membrane disease, persistent pulmonary hypertension, severe respiratory failure, and(More)
The survival of 163 infants born within the hospital at 24-28 weeks gestation during a 4 1/2-year period and the morbidity in survivors at 2 years of age were reported. Hospital survival rates from 24-28 weeks at each week of gestation, excluding six infants with birth defects, were 36%, 32%, 57%, 70% and 74% respectively. The late outcome of children born(More)
OBJECTIVE To compare the perinatal characteristics, neonatal morbidity and mortality of preterm singletons, twins and triplets born at 22-31 weeks' gestation and admitted to neonatal intensive care units (NICU) in New South Wales and Australian Capital Territory between 1994 and 2005. METHODS Perinatal characteristics and neonatal outcome data were(More)
All 56 infants born between 23 and 28 weeks' gestation admitted to this hospital in 1981 were examined for periventricular haemorrhage with cerebral ultrasonography. Haemorrhage was diagnosed in 34 (61%)-12 (22%) had germinal layer haemorrhage, 18 (32%) had intraventricular haemorrhage, and four (7%) had intracerebral haemorrhage. The two year outcome of(More)
OBJECTIVES To assess risk-adjusted early (within 7 days) mortality and major morbidities of newborn infants at < 32 weeks' gestation who are admitted after office hours to a regional Australian network of NICUs where statewide caseload is coordinated and staffed by on-floor registrars working in shift rosters. We hypothesize that adverse sequelae are(More)
