What MEWS score triggers a rapid response?

Most institutions use a MEWS of 4-5 or higher to trigger increased monitoring and clinician review, with MEWS 5 or higher typically activating a rapid response team or ICU consult.

How does MEWS compare to NEWS2?

NEWS2 is more comprehensive (6 parameters including SpO2) and has been adopted as the UK national standard. MEWS (5 parameters, no SpO2) is simpler but has slightly lower discrimination.

Is MEWS validated for all patient populations?

MEWS was developed in general ward patients. It performs less well in obstetric patients (normal physiology differs) and those with chronic disease affecting baseline parameters.

Modified Early Warning Score (MEWS)

Calculate the Modified Early Warning Score (MEWS) to identify patients at risk for clinical deterioration. Five parameters: systolic BP (0-3), heart rate (0-3), respiratory rate (0-3), temperature (0-2), and AVPU consciousness level (0-3). Total 0-14; score 5 or higher associated with increased risk of ICU admission or death.
