Early warning score adjusted for age to predict the composite outcome of mortality cardiac arrest or unplanned intensive care unit admission using observational vital-sign data: a multicentre development and validation

摘要

Early warning scores (EWS) alerting for in-hospital deterioration are commonly developed using routinely collected vital-sign data from the whole in-hospital population. As these in-hospital populations are dominated by those over the age of 45 years, resultant scores may perform less well in younger age groups. We developed and validated an age-specific early warning score (ASEWS) derived from statistical distributions of vital signs.
