Early warning scores: are they clinically relevant?

Identification of septic patients is a real challenge in emergency medicine because of various clinical manifestations and delay to obtain some biological parameters such as microbiological sampling. However, this screening must be as early as possible in order to start hemodynamic optimization and antibiotic therapy adapted to the clinical severity of patient. In this context, several strategies for screening septic patients, including the use of early warning scores (EWS), have often been studied.
