Kidney Failure Risk Calculator

The Kidney Failure Risk Calculator estimates a patient’s 2‑ and 5‑year probability of developing kidney failure (dialysis or transplant) using age, sex, eGFR, and albuminuria.

Indications d'utilisation

Used for adults with CKD G3–G5 to estimate 2- and 5-year kidney failure risk and guide referral, multidisciplinary care, and KRT planning (

Use an externally validated risk equation in CKD G3–G5 to estimate absolute kidney failure risk. 1 [Level I evidence]

).
• Supports nephrology referral at 5-year risk ≥3–5%, team‑based care at 2‑year risk >10%, and dialysis/transplant preparation at 2‑year risk >40% 2 [Level I evidence].

Informations et précautions

Provides accurate 2–5 yr kidney failure risk using age, sex, eGFR, and ACR; validated in >2 million individuals with excellent discrimination (C‑statistic ~0.88–0.91) 1.
Use only in CKD G3–G5 and avoid in AKI or CKD G1–G2 where calibration is unreliable 1.
Risk may be overestimated outside North America unless locally calibrated 2.
