Formula
MEWS = Systolic BP (0–3) + Heart Rate (0–3) + Resp Rate (0–3) + Temperature (0–2) + AVPU (0–3)
MEWS ≥ 5 or any single score of 3 triggers Immediate Rapid Response Team activation.Clinical Pearls

Limitations
MEWS is calibrated for adult general ward patients; pregnant patients must use Modified Obstetric Early Warning Score (MEOWS), and children require PEWS.
