Chronic Kidney Disease: A New Classification and Staging System

It therefore cannot be overstated that recognition of this chronic condition is crucial to facilitate the employment of measures that can slow progression to endstage renal disease (ESRD). Also, appropriate and timely interventions in patients with CKD would enhance therapy of comorbid conditions, reduce associated complications, and improve patient outcomes. These are certainly achievable goals, as many effective therapies for slowing the progression of CKD and correcting or reducing associated comorbidities have become available in the past few decades. 5‐7 To this end, a system to classify stages of CKD is justified to permit a logical approach to diagnosis and therapy in these patients. A working group of the National Kidney Foundation (NKF) recently published clinical practice guidelines to aid physicians in diagnosing and managing CKD. 8
