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

Apply the Confusion Assessment Method for the ICU (CAM-ICU) to diagnose delirium in mechanically ventilated patients using four features: acute onset, inattention, altered consciousness, and disorganized thinking

Each component has a specific meaning:

  • Four features: acute onset — The four features: acute onset recorded for the scenario being assessed.
  • Inattention — The inattention recorded for the scenario being assessed.
  • Altered consciousness — The altered consciousness recorded for the scenario being assessed.
  • Disorganized thinking — The disorganized thinking recorded for the scenario being assessed.

Note: Interpret the cam-icu result against the thresholds and context described above.

How to Use

Enter the four features: acute onset, inattention, altered consciousness, disorganized thinking for the scenario you are assessing. Apply the Confusion Assessment Method for the ICU (CAM-ICU) to diagnose delirium in mechanically ventilated patients using four features: acute onset, inattention, altered consciousness, and disorganized thinking. Use the cam-icu result to inform your calculation.
