Table 3 Sensitivity, Specificity, and Positive (PPV) and Negative Predictive Values (NPV) for severe sepsis by different identification tools in the Emergency department (n = 108 cases of severe sepsis among 1535 patients)

From: Poor performance of quick-SOFA (qSOFA) score in predicting severe sepsis and mortality – a prospective study of patients admitted with infection to the emergency department

  1. aThe ability to identify sepsis in % is calculated based on 108 cases of sepsis in the total population, whilst the sensitivity analysis is based on the 103 cases with complete score on qSOFA
