MEWS (Modified Early Warning Score)
Modified Early Warning Score (Subbe 2001): SBP, pulse, respiratory rate, temperature (Celsius), and AVPU each banded to 0-3; aggregate with the Subbe risk band and per-parameter breakdown.

Example
- Systolic BP
- 120 mmHg
- Pulse
- 78 bpm
- Respiratory rate
- 14 breaths/min
- Temperature
- 37.0 C
- Consciousness
- A - Alert
Result: MEWS 0 - low band (0-2) per Subbe 2001 Table 2.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- 0-2
- Low risk band per Subbe 2001 Table 2.
- 3
- Low-intermediate risk band per Subbe 2001 Table 2.
- 4
- Intermediate risk band per Subbe 2001 Table 2.
- >=5
- Increased risk of death, ICU admission, and HDU admission per Subbe 2001 Table 2.
What you enter
