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 the Pediatric Early Warning Score using behavior, cardiovascular, and respiratory domain scores to identify children at risk of clinical deterioration requiring urgent intervention

Each component has a specific meaning:

  • Behavior — The behavior recorded for the scenario being assessed.
  • Cardiovascular — The cardiovascular recorded for the scenario being assessed.

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

How to Use

Enter the behavior, cardiovascular for the scenario you are assessing. Calculate the Pediatric Early Warning Score using behavior, cardiovascular, and respiratory domain scores to identify children at risk of clinical deterioration requiring urgent intervention. Use the pews result to inform your calculation.
