THRIVE Score (stroke outcome)
THRIVE score (Flint 2013): predicts good functional outcome and mortality after acute ischemic stroke (0-9).

Example
- Baseline NIHSS
- 22
- Age
- 82
- History of hypertension
- Yes
- History of diabetes
- Yes
- History of atrial fibrillation
- Yes
Result: THRIVE 9/9: high risk (THRIVE III) -- good outcome (mRS 0-2) ~10.6%, 90-day mortality ~56.4%.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Outcome
- low band (0-2) ~64.7% good outcome / 5.9% mortality; high band (6-9) ~10.6% / 56.4%; the middle band (3-5) is intermediate.
What you enter
- Baseline NIHSS
- Age (years)
- History of hypertension
- History of diabetes
- History of atrial fibrillation
How this is calculated
- Components
- baseline NIHSS (<= 10 = 0, 11-20 = +2, >= 21 = +4), Age (<= 59 = 0, 60-79 = +1, >= 80 = +2), and +1 each for hypertension, diabetes, and atrial fibrillation, summed 0-9.
