Table 1 Definitions for the stage of AKI: using the AKI network criteria

From: Do acute elevations of serum creatinine in primary care engender an increased mortality risk?

Stage

Serum creatinine criteria

Stage 1

1.5 – 1.9 times baseline creatinine OR an increase in serum creatinine of > 0.3 mg/dl (>26.5mmols/l*)

Stage 2

2.0 – 2.9 times baseline creatinine 0.5 ml/kg/h for X12 hours

Stage 3

3.0 times the baseline OR Increase in serum creatinine to >4.0 mg /dl (353.6 mmols/l**)

  1. This table shows the Acute Kidney Injury Network serum creatinine criteria, which was used to stratify the primary care cohort. *AKI defined only using these criteria has been referred to as AKI 1a in this paper. **AKI defined only using these criteria had been referred to as AKI 3a.19
