THRIVE 0-2. Good outcome (mRS 0-2) in roughly half or more; low mortality.
- Risk group
- THRIVE 0-2
When to use
- Estimating likelihood of good functional outcome and mortality after acute ischaemic stroke, including after endovascular therapy.
Formula
Points: NIHSS (0-10 = 0, 11-20 = 2, 21-42 = 4), age (<=59 = 0, 60-79 = 1, >=80 = 2), and one point each for hypertension, diabetes, and atrial fibrillation. Range 0-9; higher scores predict worse outcome.
Pearls and pitfalls
- Higher THRIVE scores track with lower rates of good functional outcome and higher mortality across treated and untreated cohorts.
