Abstract 19520: Trends in Renal Complication Rates Among Medicare Beneficiaries Undergoing PCI: Fiscal Years 2009 Through 2013
Background: Enhanced attention has focused on contrast induced nephropathy among patients undergoing PCI. This study reports five-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) 2009 through 2013. The study sample consists of 1,552,960 Medicare Beneficiaries (MB) undergoing a PCI without CABG or valve surgery. Up to 25 ICD-9-CM procedure and diagnosis codes were use to identify the outcomes of interest. POA flags were used to identify patients who experienced complications from those patients admitted with the comorbidity. The analysis is descriptive.
Results: This analysis identifies that both new acute renal failure (ARF) and new hemodialysis (HD) increased dramatically during this period. The incidence of new HD essentially doubled in MB’s undergoing PCI during an admission. MB undergoing elective PCIs were less likely than MBs undergoing non-elective PCI to experience ARF (both present on admission and as a complication). However, MB undergoing elective PCIs were more likely than MBs undergoing non-elective PCI to have had a prior HD and experience new HD than MBs undergoing non-elective PCI.
Conclusion: These findings suggest, that despite a longstanding focus on preventing CIN, the complication is increasing steadily and that new efforts to reduce PCI related CIN are warranted.
