RESULTS: One hundred nineteen patients (69% from the emergency department, 31% form hospital wards) had suspected infection and were included in this study. Twenty-two (19%) of those patients died in the hospital, 56% had positive cultures and 20% had microbiologically confirmed bacteremia. Of the included patients, 40% were qSOFA-negative and 11% were SIRS-negative before ICU admission. Patients with positive qSOFA had higher in-hospital mortality compared to those with negative qSOFA (25% vs 8%, p = 0.03). There was no difference between SIRS-positive and SIRS-negative patients in terms of in-hospital mortality (p = 0.45). The discrimination of hospital mortality using qSOFA was adequate [area under the receiver operating characteristic curve (AUROC) = 0.70; 95% confidence intervals (CI), 0.58-0.82]. The discrimination of hospital mortality using SIRS was poor (AUROC = 0.58; 95% CI, 0.45-0.70).
