Clinical Recommendations
Step-by-Step Calculation
MEWS uses 5 vital sign parameters to identify patients at risk of clinical deterioration.
SBP: 120 mmHg
Points: 0 (≤70=3, 71-80=2, 81-100=1, 101-199=0, ≥200=2)
HR: 80 bpm
Points: 0 (<40=2, 41-50=1, 51-100=0, 101-110=1, 111-129=2, ≥130=3)
RR: 16/min
Points: 1 (<9=2, 9-14=0, 15-20=1, 21-29=2, ≥30=3)
Temp: 37°C
Points: 0 (<35=2, 35-38.4=0, ≥38.5=2)
AVPU: Alert - Fully awake and oriented
Points: 0 (A=0, V=1, P=2, U=3)
MEWS = SBP + HR + RR + Temp + AVPU
MEWS = 0 + 0 + 1 + 0 + 0 = 1
Risk Level: Low (Score 0-1)
Action: Continue routine vital signs
MEWS Score Reference
| Score Range | Risk Level | Action Required | Monitoring |
|---|---|---|---|
| 0-1 | Low | Continue routine vital signs | Every 8-12 hours (routine) |
| 2-3 | Medium-Low | Increase monitoring frequency | Continuous monitoring |
| 4 | Medium | Hourly observations, urgent review | Hourly |
| 5-6 | High | Continuous monitoring if possible | Continuous monitoring |
| ≥7 | Critical | Emergency team activation | Continuous monitoring |

📋 What is the MEWS Score?
The Modified Early Warning Score (MEWS) is a track-and-trigger system that uses 5 physiological parameters to identify patients at risk of deterioration and trigger appropriate clinical response.
Five Parameters
- • Systolic Blood Pressure
- • Heart Rate
- • Respiratory Rate
- • Temperature
- • Level of Consciousness (AVPU)
⚡ Response Protocol
- MEWS 0-1: Routine monitoring (8-12 hourly)
- MEWS 2-3: Increase monitoring (4 hourly)
- MEWS 4: Hourly monitoring, notify physician
- MEWS ≥5: Immediate physician review, consider ICU
