DRAGON Score for tPA Outcome

Predict 3-month functional outcome after IV tPA in ischemic stroke using the DRAGON score incorporating glucose, onset-to-treat time, NIHSS, and CT findings.

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

Predict 3-month functional outcome after IV tPA in ischemic stroke using the DRAGON score incorporating glucose, onset-to-treat time, NIHSS, and CT findings

Each component has a specific meaning:

  • Onset-to-treat time — The onset-to-treat time recorded for the scenario being assessed.
  • NIHSS — The nihss recorded for the scenario being assessed.
  • CT findings — The ct findings recorded for the scenario being assessed.

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

How to Use

Enter the onset-to-treat time, NIHSS, CT findings for the scenario you are assessing. Predict 3-month functional outcome after IV tPA in ischemic stroke using the DRAGON score incorporating glucose, onset-to-treat time, NIHSS, and CT findings. Use the dragon score result to inform your calculation.
