Romaine ST, Sefton G, Lim E, et al. - Given that Paediatric Early Warning Scores (PEWS) are commonly used in the UK, but the heterogeneity across tools and the limited data on their predictive performance represent obstacles to improving best practice, researchers conducted this retrospective single-centre cohort study to compare the performance of the National PEWS with six other PEWS currently used in NHS hospitals, for their ability to predict critical care (CC) admission in febrile children attending the emergency department (ED). In total, 11,449 eligible febrile ED attendances were identified from the electronic patient record over a 2-year period. The findings support the use of the proposed National PEWS in paediatric EDs for the detection of suspected sepsis in order to improve outcomes, but further testing in other settings and presentations is needed.
