Description

The JAMA kidney failure risk equation is a model including the variables age, sex, estimated GFR, albuminuria, serum calcium, serum phosphate, serum bicarbonate, and serum albumin which is used to predict progression to kidney failure in patients with chronic kidney disease (CKD). Reference: Tangri, N., Stevens, L. A., Griffith, J., Tighiouart, H., Djurdjev, O., Naimark, D., ... & Levey, A. S. (2011). A predictive model for progression of chronic kidney disease to kidney failure. Jama, 305(15), 1553-1559. Publication granted by Navdeep Tangri.

JAMA kidney failure risk score
Description

P (event) = Probability of kidney failure at 5 years. Score < -41 = P (Kidney Failure) > 90% Score > -3 = P (Kidney Failure) < 5% Between -3 and -41, please refer to the chart below: Score P(event) -41 89.0% -21 26.4% -40 86.9% -20 24.2% -39 84.1% -19 22.2% -38 81.0% -18 20.3% -37 77.8% -17 18.6% -36 74.4% -16 17.0% -35 70.9% -15 15.5% -34 67.3% -14 14.1% -33 63.6% -13 12.9% -32 59.9% -12 11.7% -31 56.3% -11 10.7% -30 52.8% -10 9.7% -29 49.3% -9 8.8% -28 45.9% -8 8.0% -27 42.7% -7 7.3% -26 39.6% -6 6.6% -25 36.6% -5 6.0% -24 33.8% -4 5.5% -23 31.2% -22 28.7%
