Table 1 Acute kidney injury mortality (adults) and prevalence (pediatric) by different baseline creatinine values
From: Clinical review: RIFLE and AKIN – time for reappraisal
Method for estimating baseline creatinine | No acute kidney injury | Risk (%) | Injury (%) | Failure (%) |
|---|---|---|---|---|
Crude mortality by RIFLE class (adults) | ||||
Hospital admission | 12.4 | 21.7 | 34.5 | 40.6 |
ICU admission | 12.7 | 21.7 | 31.2 | 38.4 |
Lower of hospital or ICU admission | 10.4 | 16.0 | 36.0 | 41.5 |
Estimate from MDRD formula | 5.7 | 12.7 | 25.2 | 34.9 |
Lower of hospital or ICU admission or MDRD estimate | 7.2 | 12.9 | 24.3 | 35.7 |
Nadir creatinine (first week) | 9.7 | 13.1 | 25.9 | 30.1 |
Nadir creatinine (whole admission) | 8.9 | 11.0 | 22.1 | 28.7 |
Acute kidney injury prevalence by pediatric RIFLE class (pediatric ICU) | ||||
Estimated creatinine clearance of 120 ml/min/1.73 m2 | 36.5 | 17.1 | 24.4 | 22.0 |
Estimated creatinine clearance of 100 ml/min/1.73 m2 | 17.1 | 14.6 | 36.6 | 31.7 |
ICU admission | 87.9 | 7.3 | 2.4 | 2.4 |
Normal value for age and gender (minimum) | 12.2 | 12.2 | 39.0 | 36.6 |
Normal value for age and gender (maximum) | 46.3 | 14.6 | 17.1 | 22.0 |
