Summary of recommendation statements and practice points relevant to risk assessment in people with CKD in the 2024 KDIGO Guideline and differences from the 2012 KDIGO Guideline.

2.1 Overview on monitoring for progression of CKD based upon GFR and ACR categories
Practice point 2.1.1: Assess albuminuria in adults, or albuminuria/proteinuria in children, and GFR at least annually in people with CKDIn agreement with 2012 KDIGO CKD Guideline
Practice point 2.1.2: Assess albuminuria and GFR more often for individuals at higher risk of CKD progression when measurement will impact therapeutic decisions.
Practice point 2.1.3: For people with CKD, a change in eGFR of >20% on a subsequent test exceeds the expected variability and warrants evaluationIntroducing cutoffs for eGFR change, in general and in patients initiating haemodynamically active therapies, which should prompt further evaluation
Practice point 2.1.4: Among people with CKD who initiate haemodynamically active therapies, GFR reductions of >30% on subsequent testing exceed the expected variability and warrant evaluation
Practice point 2.1.5: For albuminuria monitoring of people with CKD, a doubling of the ACR on a subsequent test exceeds laboratory variability and warrants evaluationDefining a doubling in albuminuria or more as exceeding the expected variability and warranting evaluation
2.2 Risk prediction in people with CKD
Recommendation 2.2.1: In people with CKD G3–G5, we recommend using an externally validated risk equation to estimate the absolute risk of kidney failure (1A)Highlights the need and potential benefits on the use of validated risk equations to estimate the absolute risk of outcomes for each individual and enable a personalized care plan for people with CKD
Practice point 2.2.1: A 5-year kidney failure risk of 3%–5% can be used to determine need for nephrology referral in addition to criteria based on eGFR or urine ACR, and other clinical considerations
Practice point 2.2.2: A 2-year kidney failure risk of >10% can be used to determine the timing of multidisciplinary care in addition to eGFR-based criteria and other clinical considerations
Practice point 2.2.3: A 2-year kidney failure risk threshold of >40% can be used to determine the modality education, timing of preparation for KRT including vascular access planning or referral for transplantation, in addition to eGFR-based criteria and other clinical considerations
Practice point 2.2.4: Note that risk prediction equations developed for use in people with CKD G3–G5, may not be valid for use in those with CKD G1–G2
Practice point 2.2.5: Use disease-specific, externally validated prediction equations in people with immunoglobulin A nephropathy and autosomal dominant polycystic kidney disease
Practice point 2.2.6: Consider the use of eGFRcys in some specific circumstances
2.3 Prediction of cardiovascular risk in people with CKD
Practice point 2.3.1: For cardiovascular risk prediction to guide preventive therapies in people with CKD, use externally validated models that are either developed within CKD populations or that incorporate eGFR and albuminuriaHighlighting the potential benefits of the use of cardiovascular and mortality risk equations in the CKD population
Practice point 2.3.2: For mortality risk prediction to guide discussions about goals of care, use externally validated models that predict all-cause mortality specifically developed in the CKD population
