Financial Impact of Acute Kidney Injury After Cardiac Operations in the United States [1]
The Nationwide Inpatient Sample was interrogated for all patients undergoing either CABG, valve replacement, or both from 2008 to 2011, and a total of 1,078,036 patients were included in the analysis. The authors discovered that, overall, 9.8% of patients developed acute kidney injury (AKI) postoperatively. Other important discoveries were:
Outcome non-AKI AKI p
- Death 1.3% 13.9% <0.001
- Mean hospital cost $38,820 $77,178 <0.001
The authors calculate that the net effect of AKI after cardiac surgery at a national level in the United States is over $1 billion annually.
