Multicentre validation of a sepsis prediction algorithm using only vital sign data in the emergency department, general ward and ICU

Abstract

<i>InSight</i> outperforms existing sepsis scoring systems in identifying and predicting sepsis, severe sepsis and septic shock. This is the first sepsis screening system to exceed an AUROC of 0.90 using only vital sign inputs. <i>InSight</i> is robust to missing data, can be customised to novel hospital data using a small fraction of site data and retains strong discrimination across all institutions.
