Assess chronic kidney disease (CKD) stage and progression risk using creatinine, eGFR, and comorbidity status. Clinical reference tool for identifying kidney disease severity and need for nephrology consultation.

Formula

CKD Stage determined by eGFR; Progression Risk = Age × 0.02 + eGFR × -0.01 + Comorbidities
  • Stage 1: eGFR ≥90; Stage 2: 60-89; Stage 3a: 45-59; Stage 3b: 30-44; Stage 4: 15-29; Stage 5: <15

Moderate CKD

Inputs
  • Age (years): 60 years
  • Serum Creatinine (mg/dL): 2.5 mg/dL
  • eGFR (mL/min/1.73m²): 35 mL/min
  • Diabetes: yes
  • Hypertension: yes

eGFR 35 = Stage 3b CKD. With diabetes + hypertension = ~15% 5-year progression risk.

Frequently asked questions

What does progression mean?
Worsening kidney function that may eventually lead to kidney failure requiring dialysis or transplant.
