Abstract 10118: Trends in Renal Complication Rates Among Medicare Beneficiaries Undergoing Percutaneous Coronary Interventions: Fiscal Years 2006 through 2009
Objective: Enhanced attention has focused on contrast induced nephropathy among patients undergoing PCI. This study reports four year trends in the rate of renal complications among Medicare Beneficiaries (MB) undergoing PCI.
Methods: A retrospective analysis was conducted using annual MedPar data files for fiscal years (FY) 2006 through 2009. The study sample consists of 1,373,663 Medicare Beneficiaries (MB) undergoing a PCI without CABG or valve surgery. ICD-9-CM procedure and diagnosis codes were used to identify the outcomes of interest as well as the co-morbidities used for risk-adjustment. PCI hospitalizations were reported as either elective PCIs or PCI with a primary STEMI or cardiogenic shock. Separate multivariate logistic regression models were estimated to calculate annual risk-adjusted outcomes by year.
Findings: The table indicates that MBs in both sub-populations were more likely to experience each of the risk-adjusted renal outcomes reported during FY-2009 than in any of the three previous FYs. For example, MBs were 1.8 times more likely to experience new onset hemodialysis in FY-2009 compared to FY-2006 in the elective PCI group.
Conclusion: Recent trends in renal complications among MB suggest the current focus on contrast induced nephropathy to reduce renal complications is warranted.
