Predicts progression to kidney failure in patients with chronic kidney disease (CKD).
Formula
The probability of kidney failure at 5 years is calculated by the following formula: North America Probability = 1 - 0.9096 x Non-North America Probability = 1 - 0.9245 x Where x = exp(-0.1992 × (age/10 - 7.036) + 0.1602 × (male - 0.5642) - 0.4919 × (eGFR/5 - 7.222) + 0.3364 × (log( ACR )- 5.137) - 0.3441 × (albumin - 3.997) + 0.2604 × (phosphorous - 3.916) - 0.07354 × (bicarbonate - 25.57) - 0.2228 × (calcium - 9.355))
Pearls / Pitfalls
Derived and initially validated in data from patients in nephrology clinics; likely has limited validity in patients who are acutely ill.
Management
Lower-risk patients may be best managed by a primary care physician, with higher-risk patients likely benefiting from management by a nephrologist.
