Development and validation of an early warning tool for sepsis and decompensation in children during emergency department triage

Abstract This study was designed to develop and validate an early warning system for sepsis based on a predictive model of critical decompensation. Data from the electronic medical records for 537,837 visits to a pediatric Emergency Department (ED) from March 2013 to December 2019 were collected. A...
