Classifies chronic kidney disease (CKD) using GFR and ACR categories as set by the KDIGO Work Group, prognosticates on the risk of adverse outcome of CKD and gives recommendations on the frequency of monitoring of GFR and ACR annually in individuals with CKD.
This guide classifies chronic kidney disease (CKD) using GFR and ACR categories based on the Kidney Disease: Improving Global Outcomes (KDIGO) Chronic Kidney Disease Work Group.
Use to classify chronic kidney disease to 1 of 18 possible stages, based on KDIGO GFR and ACR categories. The KDIGO-CKD classification takes the form of any combination of GFR category (G1, G2, G3a, G3b, G4, G5) and ACR category (A1, A2, A3), so that the least severe stage of CKD is classified as G1A1 and the most severe is classified as G5A3. This classification is useful for staging and evaluating CKD. It is also useful for predicting the progression and prognosis of CKD (risk of adverse outcome) and also helps determine the frequency of monitoring (number of times per year) of GFR and ACR in individuals with CKD. Increased ACR (higher ACR category) and decreased GFR (higher GFR category) is associated with increased risk of adverse outcomes and increased frequency of monitoring. Low risk: G1A1, G2A1. Moderately increased risk: G1A2, G2A2, G3aA1. High risk: G1A3, G2A3, G3aA2, G3bA1. Very high risk: G3aA3, G3bA2, G3bA3, G4A1, G4A2, G4A3, G5A1, G5A2, G5A3. Monitor one (1) time annually: G1A1, G1A2, G2A1, G2A2, G3aA1. Monitor two (2) times annually: G1A3, G2A3, G3aA2, G3bA1. Monitor three (3) times annually: G3aA3, G3bA2, G3bA3, G4A1, G4A2. Monitor four (4) or more times annually: G4A3, G5A1, G5A2, G5A3. Additional information about these categories and the GFR/ACR intervals they represent is available in the respective GDL applications for GFR assessment and ACR assessment.
