The mortality of sepsis patients presented by the Emergency Medical Services (EMS) with unrecognized sepsis is twice as high as in patients with documented sepsis [1]. To improve the (pre)-hospital recognition of septic patients, the investigators of the Prehospital Antibiotics Against Sepsis study (PHANTASi) trial educated EMS nurses in recognizing sepsis and implemented a sepsis protocol in the ambulances [2]. Immediately after this training, the prehospital recognition of sepsis by the EMS personel significantly improved from 14 to 41%[2–5].
