From: Prognostic value of procalcitonin in respiratory tract infections across clinical settings
Association between time to severe adverse events and admission procalcitonin levels in emergency department patients. (A) Time to treatment failure is significantly shorter in emergency department (ED) patients with higher procalcitonin (PCT) levels on admission. (P <0.0001. (B) Time to death is significantly shorter in ED patients with higher PCT levels on admission (P <0.02). Treatment failure is defined as death, ICU admission, rehospitalisation, complications or recurrent or worsening infection within 28Â days.
