Diagnostic accuracy of small-for-gestational-age status for infant mortality and school-age outcomes of live births <28 weeks' gestation: a cohort study.

Objectives: To determine the diagnostic accuracy of small-for-gestational-age (SGA; <10th centile) status for infant mortality and adverse school-age outcomes in infants born extremely preterm (EP; <28 weeks' gestation).

Design: Geographical cohort studies.

Setting: The state of Victoria, Australia.

Protocol for a randomised controlled trial comparing two CPAP levels to prevent extubation failure in extremely preterm infants.

Introduction: Respiratory distress syndrome is a complication of prematurity and extremely preterm infants born before 28 weeks' gestation often require endotracheal intubation and mechanical ventilation. In this high-risk population, mechanical ventilation is associated with lung injury and contributes to bronchopulmonary dysplasia. Therefore, clinicians attempt to extubate infants as quickly and use non-invasive respiratory support such as nasal continuous positive airway pressure (CPAP) to facilitate the transition.

Very preterm birth before arrival at hospital.

Background: Our aim was to report perinatal characteristics of very preterm births before arrival (BBAs) at a hospital, and perinatal and infant mortality rates up to one year, comparing BBAs with births in a hospital.

Materials And Methods: A population-based cohort study of 22-31 weeks' gestation births in the state of Victoria, Australia from 1990-2009. BBAs were defined as unintentional births at home or on route to hospital.

Outcomes of infants born at 22-27 weeks' gestation in Victoria according to outborn/inborn birth status.

Objectives: To compare mortality and serious morbidity rates between outborn and inborn livebirths at 22-27 weeks' gestation.

Design: Population-based cohort study.

Setting: Victoria, Australia.

What are we telling the parents of extremely preterm babies?

Background: Parent counselling and decision-making regarding the management of preterm labour and birth are influenced by information provided by healthcare professionals regarding potential infant outcomes.

Aim: The aim of this study was to determine whether perinatal healthcare providers had accurate perceptions of survival and major neurosensory disability rates of very preterm infants born in non-tertiary hospitals ('outborn') and tertiary perinatal centres ('inborn').

Materials And Methods: A web-based survey was distributed to midwives, nurses, obstetricians and neonatologists working in non-tertiary and tertiary maternity hospitals, and the perinatal/neonatal emergency transport services in Victoria, Australia.

Why birthplace still matters for infants born before 32 weeks: Infant mortality associated with birth at 22-31 weeks' gestation in non-tertiary hospitals in Victoria over two decades.

Background: Very preterm infants born in non-tertiary hospitals ('outborn') are known to have higher mortality rates compared with infants 'inborn' in tertiary centres.

Aim: The aim of this study was to report changes over time in the incidence of outborn livebirths, 22-31 weeks and infant mortality rates for outborn compared with inborn births.

Methods: We conducted a population-based cohort study of consecutive livebirths, 22-31 weeks' gestation in Victoria from 1990 to 2009.
