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)
The aims of the study were to use the population base of New South Wales (NSW) to study all births from 20 to 27 weeks' gestation in 1992-3 and to compare two data sources for perinatal deaths. The prospective population-based statewide audit (NICUS) of infants admitted to tertiary neonatal intensive care units (NICUs) in NSW was used to collect data on(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)
AIMS 1. Ascertain antenatal and intrapartum risk factors for term neonates ventilated primarily for respiratory problems. 2. Describe the neonatal morbidity and mortality. METHODS Population-based case control cohort study. SETTING Sydney and four large rural/urban Health Areas in New South Wales, 1996. SUBJECTS Singleton term infants, no major(More)
Perinatal care at the borderlines of viability demands a delicate balance between parents' wishes and autonomy, biological feasibility, clinicians' responsibilities and expectations, and the prospects of an acceptable long-term outcome - coupled with a tolerable margin of uncertainty. A multi-professional workshop with consumer involvement was held in(More)
Linked administrative population data were used to estimate the burden of childhood respiratory syncytial virus (RSV) hospitalization in an Australian cohort aged <5 years. RSV-coded hospitalizations data were extracted for all children aged <5 years born in New South Wales (NSW), Australia between 2001 and 2010. Incidence was calculated as the total number(More)
During 1979 and 1980, 351 infants of birth weight 500 to 999 g were born in the State of Victoria: 89 (25.4%) survived to the age of 2 years corrected for prematurity, and 83 were fully assessed by a multidisciplinary team; partial data were obtained on the remainder. At the age of 5 years, corrected for prematurity, 85/89 (96%) were evaluated by a(More)
The neonatal units in two large maternity hospitals collaborated in a study of 440 liveborn infants weighting 500-1500 g born in 1977 and 1978: 377 (85.7%) were born in hospital. The overall survival rate was 70.5%, with a range of 67.5% to 71.5% for the inborn and outborn categories of infants in each hospital. In hospital A the survival rate of infants(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)
