RIFLE Acute Kidney Injury Criteria

Stage acute kidney injury using the RIFLE criteria (Risk, Injury, Failure, Loss, End-stage) based on serum creatinine rise, GFR reduction, and urine output to guide nephrology consultation.

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

Stage acute kidney injury using the RIFLE criteria (Risk, Injury, Failure, Loss, End-stage) based on serum creatinine rise, GFR reduction, and urine output to guide nephrology consultation

Each component has a specific meaning:

  • RIFLE criteria (Risk — The rifle criteria (risk recorded for the scenario being assessed.
  • Injury — The injury recorded for the scenario being assessed.
  • Failure — The failure recorded for the scenario being assessed.
  • Loss — The loss recorded for the scenario being assessed.
  • End-stage) based on serum creatinine rise — The end-stage) based on serum creatinine rise recorded for the scenario being assessed.
  • GFR reduction — The gfr reduction recorded for the scenario being assessed.

Note: Interpret the rifle aki result against the thresholds and context described above.

How to Use

Enter the RIFLE criteria (Risk, Injury, Failure, Loss, End-stage) based on serum creatinine rise, GFR reduction for the scenario you are assessing. Stage acute kidney injury using the RIFLE criteria (Risk, Injury, Failure, Loss, End-stage) based on serum creatinine rise, GFR reduction, and urine output to guide nephrology consultation. Use the rifle aki result to inform your calculation.
