Cost to Medicare of acute kidney injury in percutaneous coronary intervention
Authors' conclusion
AKI, and specifically CI-AKI, during PCI is associated with significantly longer PCI admission LOS, PCI admission costs, and long-terms costs.
Study context
- Population
- Medicare fee-for-service patients undergoing inpatient percutaneous coronary intervention (PCI), January 2017–June 2020
- Participants
- 509,039 patients
- Exposure
- Acute kidney injury (AKI) vs no AKI during PCI admission
- AKIn = 104,033
- Contrast-induced AKI (CI-AKI)n = 9,691
- Outcome
- PCI admission LOS and cost (Medicare paid amount, 2022 US$), and total costs
- Follow-up
- 1 year after PCI (total costs)
