At present, identification is dependent on the suspicion of sepsis and by health care professionals applying clinical judgment. Traditionally, the definition of sepsis has been based on the presence of infection and a minimum of two SIRS criteria (Systemic Inflammatory Response Syndrome), which have, however, been shown to be both un-sensitive and non-specific. The investigators have in previous studies proved proof of principle that a screening tool increases the identification of the septic patient and is superior to clinical judgment among both ambulance personnel and ED doctors. Moreover, these studies also illustrate that current screening tools do not identify all septic patients.
