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

Estimate 6-month outcome probability after Traumatic Brain Injury using the IMPACT model incorporating GCS, pupil reactivity, CT findings, and age

Each component has a specific meaning:

  • IMPACT model incorporating GCS — The impact model incorporating gcs recorded for the scenario being assessed.
  • Pupil reactivity — The pupil reactivity recorded for the scenario being assessed.
  • CT findings — The ct findings recorded for the scenario being assessed.
  • Age — The age recorded for the scenario being assessed.

Note: Interpret the tbi impact score result against the thresholds and context described above.

How to Use

Enter the IMPACT model incorporating GCS, pupil reactivity, CT findings, age for the scenario you are assessing. Estimate 6-month outcome probability after Traumatic Brain Injury using the IMPACT model incorporating GCS, pupil reactivity, CT findings, and age. Use the tbi impact score result to inform your calculation.
