Temporal changes in rates of active management and infant survival following live birth at 22–24 weeks' gestation in Victoria

Abstract

Background: Management of livebirths at 22–24 weeks' gestation in high-income countries varies widely and has changed over time. Aims: Our aim was to determine how rates of active management and infant survival of livebirths at 22–24 weeks varied with perinatal variables known at birth, and over time in Victoria, Australia. Materials and methods: We conducted a population-based cohort study of all 22–24 weeks' gestation live births, free of lethal congenital anomalies in 2009–2017. Rates of active management and survival to one year of age were reported. ‘Active management’ was defined as receiving resuscitation at birth or nursery admission for intensive care. Results: Over the nine-year pe..
