Nee R, et al. - Researchers used the US Renal Data System database to determine how percutaneous coronary intervention (PCI) use differs by the race between black and white patients with end-stage renal disease on maintenance dialysis. In a cohort of 268,575 Medicare-primary patients who started on maintenance dialysis, they extracted Medicare inpatient procedure claims for PCI. Among white and black patients, the estimated crude incidence rate of PCI was 25.8 per 1000 patient-years vs 15.5 per 1000 patient-years, respectively. The likelihood of undergoing PCI was significantly less among black patients vs white patients in Cox regression analyses. Findings revealed that even comprehensive coverage with Medicare could not fill the racial gap in PCI use that still exists among dialysis patients. The persistence of these results was seen despite accounting for demographic, clinical, socioeconomic factors, and death or transplant as competing events.
