<jats:bold>Objective:</jats:bold>
This study examines the trends in inpatient rates of renal complications (RCs) among Medicare Beneficiaries (MB) undergoing PCI from Fiscal Year (FY) 2009 to FY 2011, and the potential role of repeated contrast exposure during an admission, as well as other clinical factors that impact this trend.

<jats:bold>Methods:</jats:bold>
A retrospective analysis was conducted using annual MedPar data files for three FYs: 2009, 2010 and 2011. The study sample consists of 977,398 MB hospitalizations for PCI without CABG or valve surgery. Renal complications of interest were New Onset Hemodialysis (HD), ARF Complication, or either Renal Complication. Multi-variable logistic regression equations, controlling for 40 demographic and co-morbid conditions, as well as evidence of repeated same admission contrast administration (other peripheral or carotid interventions/procedures, and contrast CT scan) were estimated for each complication.

<jats:bold>Findings:</jats:bold>
The table identifies that renal complications (compared to 2009) are increasing, with MBs 1.53 times more likely to experience any renal complication. Concomitant contrast dependent imaging and therapeutic procedures, as well as established clinical risk factors, increase the likelihood.

<jats:bold>Conclusion:</jats:bold>
The adjusted incidence of renal complications following PCI among hospitalized MBs is increasing over time. In addition, repeated contrast exposure during an admission independently increases the likelihood of renal complications.
