RIFLE Criteria for Acute Renal Dysfunction
Acute Dialysis Quality Initiative (ADQI) Group has proposed the escalating RIFLE system using either glomerular filtration rate-GFR or urine output-UO to classify Acute Renal Failure (ARF):
R = Risk of renal failure - if increase in Scr is x 1.5 or decrease in GFR is > 25% or decrease in UO is < .5 ml/kg/hr x 6 hours.
I = Injury to the kidney - if increase in Scr is x 2 or decrease in GFR is > 50% or decrease in UO is < .5 ml/kg/hr x 12 hours.
F = Failure of kidney function - if increase in Scr is x 3 or decrease in GFR is > 75% or Scr > 4 mg/dl or decrease in UO is < .3 ml/kg/hr x 24 hours or Anuria x 12 hours.
L = Loss of kidney function - Persistent ARF > 4 weeks, and
E = End-stage renal failure - Persistent ARF > 3 months.
