Estimating baseline sCr method | Characteristics in the diagnosis of AKI | Reference |
---|---|---|
An estimated sCr determined by back-calculation using MDRD assuming a GFR of 75Â mL/min/1.73Â m2 | Low specificity especially in CKD patients | |
An estimated sCr determined by back-calculation using MDRD assuming a GFR of 100Â mL/min/1.73Â m2 | Very high sensitivity and very low specificity | [23] |
The first admission sCr | Low sensitivity | [22] |
A minimum inpatient sCr during the first 7Â days | Low specificity | [22] |
A minimum sCr during the first 7Â days in the ICU | Low specificity although tendency to underestimate the AKI stage | [23] |
An estimated sCr using multiple imputation methods such as sex, race, comorbidity (CKD, etc.), and a minimum inpatient sCr | High specificity | [19] |
A minimum inpatient sCr | Â | [11] |
sCr = 1.0 mg/dL (male)/0.8 mg/dL (female) |  | [25] |
