Fold change (ratio) in 28-day mortality, hospitalisation and intensive care unit (ICU) admission of patients with scores ≥2 vs. <2. a Twenty-eight-day mortality. b Hospitalisation. c ICU admission. Twenty-eight-day mortality of patients in baseline risk class 1 was zero. Twenty-eight-day mortality of patients with quick Sepsis-related Organ Failure Assessment (qSOFA) score <2 was zero in baseline risk classes 2 and 3. Twenty-eight-day mortality of patients with CRB/CRB-65 scores <2 was zero in baseline risk class 2. Prevalence of hospitalisation of patients in baseline risk class 1 was zero when the score was ≥2 for qSOFA, CRB and CRB-65. Prevalence of ICU admission was zero in patients in baseline risk classes 1 and 2. Prevalence of ICU admission was zero in patients with qSOFA score ≥2 in baseline risk class 3. Prevalence of ICU admission was zero in patients with qSOFA score <2 in baseline risk class 10. Prevalence of ICU admission was zero in patients with CRB/CRB-65 scores ≥2 in baseline risk classes 3 and 4. CRB confusion, respiratory rate ≥30/minute, systolic blood pressure <90 mmHg or diastolic blood pressure ≤60 mmHg, CRB-65 confusion, respiratory rate ≥30/minute, systolic blood pressure <90 mmHg or diastolic blood pressure ≤60 mmHg, age ≥65 years
