ADHERE In-Hospital Heart-Failure Mortality
ADHERE classification-tree mortality risk for acute decompensated heart failure, branching on BUN, systolic blood pressure, and creatinine.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- BUN
- 50 mg/dL
- Systolic BP
- 100 mmHg
- Creatinine
- 3.0 mg/dL
Result: ADHERE high risk — in-hospital mortality ≈ 21.9% (BUN ≥ 43, SBP < 115, creatinine ≥ 2.75).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Tree
- BUN ≥ 43 mg/dL, then SBP < 115 mmHg, then creatinine ≥ 2.75 mg/dL.
- Mortality
- BUN<43 & SBP≥115 low ≈ 2.1%; BUN<43 & SBP<115 ≈ 5.5%; BUN≥43 & SBP≥115 ≈ 6.4%; BUN≥43 & SBP<115 & Cr<2.75 ≈ 12.4%; BUN≥43 & SBP<115 & Cr≥2.75 high ≈ 21.9%.
What you enter
- BUN
- Systolic BP
- Creatinine (needed if BUN ≥ 43 and SBP < 115)
