Hospital procedure volume does not predict acute kidney injury after coronary artery bypass grafting-a nationwide study.

ABSTRACT:

Background

Acute kidney injury (AKI) is common after coronary artery bypass grafting (CABG) and is associated with poor outcome. Increased hospital procedure volume has been associated with better outcomes. However, the impact of hospital CABG volume on AKI needing dialysis (AKI-D) is less clear. We designed this study to examine (i) the impact of number of annual CABG procedures per hospital (CABG-vol) on AKI-D and inpatient mortality and (ii) if it modifies the relationship between AKI-D and mortality.

Methods

Using the Nationwide Inpatient Sample database from 2000 to 2010, we identified admissions with CABG and those with AKI-D using International Classification of Diseases, Ninth Revision, Clinical Modification codes. Multivariable logistic regressions were used to asse
