Table 1: NKF-K/DOQI classification of the stages of chronic kidney disease (CKD).
|Stage||GFR (mL/min/1.73 m2)||Description||Action plan*|
|1||≥ 90||Kidney damage with normal or increased GFR||Treat primary and comorbid conditions|
|Slow CKD progression, CVD risk reduction|
|2||60-89||Kidney damage with mild reduction of GFR||Estimate rate of progression of CKD|
|3||30-59||Moderate reduction of GFR||Evaluate and treat complications|
|4||15-29||Severe reduction of GFR||Prepare for kidney replacement therapy|
|5||< 15 (or dialysis)||Kidney failure||Kidney replacement therapy|
NKF: The National Kidney Foundation; K/DOQI: Kidney Disease Outcomes Quality Initiative; GFR: Glomerular Filtration Rate (millilitres per minute per 1.73-meter square of body surface area);
CVD: Cardiovascular Disease. *The actions that are listed in the more severe stages of CKD also include actions from less severe stages.
