Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Estimate risk of AKI-to-CKD transition based on AKI severity, duration, and baseline kidney function. KDIGO stage 3 AKI carries 30-40% risk of new CKD at 3 months

Each component has a specific meaning:

  • AKI severity — The aki severity recorded for the scenario being assessed.
  • Duration — The duration recorded for the scenario being assessed.
  • Baseline kidney function — The baseline kidney function recorded for the scenario being assessed.

Note: Interpret the aki to ckd transition risk result against the thresholds and context described above.

How to Use

Enter the AKI severity, duration, baseline kidney function for the scenario you are assessing. Estimate risk of AKI-to-CKD transition based on AKI severity, duration, and baseline kidney function. KDIGO stage 3 AKI carries 30-40% risk of new CKD at 3 months. Use the aki to ckd transition risk result to inform your calculation.
