Modified Early Warning Score (MEWS)

Calculate MEWS from systolic BP, heart rate, respiratory rate, temperature, and AVPU score to identify patients at risk of clinical deterioration requiring urgent review.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate MEWS from systolic BP, heart rate, respiratory rate, temperature, and AVPU score to identify patients at risk of clinical deterioration requiring urgent review

Each component has a specific meaning:

  • Systolic BP — The systolic bp recorded for the scenario being assessed.
  • Heart rate — The heart rate recorded for the scenario being assessed.
  • Respiratory rate — The respiratory rate recorded for the scenario being assessed.
  • Temperature — The temperature recorded for the scenario being assessed.

Note: Interpret the mews result against the thresholds and context described above.

How to Use

Enter the systolic BP, heart rate, respiratory rate, temperature for the scenario you are assessing. Calculate MEWS from systolic BP, heart rate, respiratory rate, temperature, and AVPU score to identify patients at risk of clinical deterioration requiring urgent review. Use the mews result to inform your calculation.
