NCDR AKI and Dialysis Risk after PCI

Estimate risk of AKI and dialysis after PCI


This risk model estimates the risk of acute kidney injury (AKI) and AKI requiring dialysis (AKI-D) after percutaneous coronary intervention (PCI).

AKI was defined as an absolute increase of >0.3 mg/dL or 26.5 µmol/L, or a relative increase of 50% in serum creatinine (AKIN Stage 1 or greater). AKI-D was defined as a new requirement for dialysis following PCI.

The model was developed based on 947 012 consecutive PCI patients at 1253 sites participating in the NCDR Cath/PCI registry between 6/09 and 7/11. 70% of patients were randomly assigned to a derivation cohort and 30% to the validation cohort.
