KDIGO 2024 Clinical Practice Guideline for the Evaluation and Management of Chronic Kidney Disease

Consolidates CKD staging, risk stratification, and disease-modifying therapy into a single framework, with expanded guidance on SGLT2 inhibitors, finerenone, and GLP-1 receptor agonists across eGFR ranges.

What changed in this edition

  • SGLT2 inhibitors recommended for most adults with CKD and eGFR ≥20 mL/min/1.73 m², with or without diabetes.
  • Finerenone added as guideline-directed therapy for CKD with type 2 diabetes and albuminuria already on RAS blockade.
  • GLP-1 receptor agonists endorsed for cardiorenal risk reduction in T2D with CKD (FLOW trial).
  • Risk stratification formally incorporates the KFRE 2- and 5-year prediction scores for referral timing.
  • Blood pressure target harmonized at SBP <120 mm Hg (standardized office measurement) when tolerated.
  • Updated albuminuria screening: annual uACR for all adults with diabetes, hypertension, or eGFR <60.
  • Cystatin C-based eGFR recommended for confirmation when creatinine-based eGFR is between 45–59 or discordant with clinical status.
  • New section on CKD in pregnancy and peri-conception planning, including safe medication substitutions.

Clinical takeaways

Who gets an SGLT2 inhibitor

Any adult with CKD and eGFR ≥20 mL/min/1.73 m² should be considered, regardless of diabetes status. Initiate and continue even as eGFR declines; discontinue only at dialysis initiation or intolerance. Expect an early reversible eGFR dip of ~4 mL/min.

Layering cardiorenal therapy

For T2D with albuminuria: start ACEi or ARB at maximum tolerated dose, add SGLT2 inhibitor, add finerenone if uACR ≥30 mg/g and K+ ≤4.8, and consider GLP-1 RA for additional cardiorenal and metabolic benefit.

Blood pressure measurement

Use standardized office BP (rested, seated, correct cuff, multiple readings averaged) or validated home BP. Do not apply the <120 target to unstandardized casual readings.

When to refer to nephrology

Refer for eGFR <30, uACR >300 mg/g, 5-year KFRE >5%, rapid eGFR decline (>5/year), resistant hypertension, or unexplained hematuria. Early referral improves vascular access planning and mortality.

Nutrition and lifestyle

Sodium <2 g/day; protein 0.8 g/kg/day (not lower) for CKD G3–G5 not on dialysis; emphasize plant-forward dietary patterns; discourage protein restriction below 0.6 g/kg.
