In a cohort of 14,795 hospitalized children, 7712 children were diagnosed with AKI according to at least one of the three definitions. A total of 5406 (70%) children were diagnosed by all three definitions. Differences in the definitions resulted in the following variances [12] :

  • 1720 were diagnosed by RIFLE alone
  • 427 were diagnosed by RIFLE and KDIGO but not AKIN
  • 153 were diagnosed by KDIBO and AKIN but not by RIFLE
  • 6 were diagnosed by KDIGO alone
