VitalPAC Early Warning Score (ViEWS) Prytherch et al. [35] Retrospective cohort study Acute medical admissions to the medical assessment unit SBP, HR, RR, BT, SpO2, oxgen supply, consciousness level In-hospital mortality within 24 h AUROC 0.888 (0.880-0.895)
Modified early warning score (MEWS) Subbe et al. [37] Prospective cohort study Medical emergency admissions admitted to the medical admissions unit SBP, HR, RR, BT, Consciousness level Admission at high dependency units (HDU), and intensive care units (ICU); cardiorespiratory emergency; death at 60 days Scores of 5 or more, death [OR 5.4 (2.8–10.7)], ICU admission [OR 10.9 (2.2–55.6)], HDU admission [OR 3.3 (1.2–9.2)]
