Abstract

Background: Although outcomes for infants born extremely low birthweight (ELBW; <1000 g birthweight) have improved over time, it is important to document survival and morbidity changes following the advent of modern neonatal intensive care in the 1990s. Objective: To describe trends in survival, perinatal outcomes and neurodevelopment to 2 years’ corrected age over time across six discrete geographic cohorts born ELBW between 1979 and 2017. Methods: Analysis of data from discrete population-based prospective cohort studies of all live births free of lethal anomalies with birthweight 500–999 g in the state of Victoria, Australia, over 6 eras: 1979–80, 1985–87, 1991–92, 1997, 2005 and 2016–17...
