G171 Survival of Preterm Infants Admitted to Neonatal Care in England: A Population-Based Study Using NHS Electronic Clinical Records

Abstract

Aims The survival of preterm infants is a matter of wide public interest. Survival prediction is important for clinicians when advising parents and for risk adjustment when comparing providers. Prediction models are generally based on historical data, often from hospital rather than population-based cohorts. Here we demonstrate the use of near-contemporaneous electronic National Health Service (NHS) clinical data to provide a practical, up-to-date, webbased survival prediction tool for preterm infants admitted to neonatal units in England. We compared this with existing UK and US predictors and evaluated the change in survival over recent years for extremely preterm babies from 22+0-25+6 week gestational age (GA) admitted to neonatal care, in comparison with previous published data. Methods Data for infants born
