BACKGROUND: Cardiovascular disease is the leading cause of death for patients with end-stage renal disease (ESRD). ESRD is known to affect a large portion of the American population. Previous data for patients undergoing percutaneous coronary intervention (PCI) in the setting of ESRD for Acute Coronary Syndrome (ACS) and non-ACS etiologies have shown to have an increase in in-hospital mortality, and prolonged hospitalization among other complications.
METHODS: The national inpatient sample (NIS) was used to identify patients who underwent PCI between the years 2016-2019. Patients were then grouped into those with ESRD on renal replacement therapy (RRT). Logistic regression models were employed to assess the primary outcome of in-hospital mortality, while linear regression models were utilized to evaluate secondary outcomes, including hospitalization cost and length of stay.
RESULTS: A total of 21,366 unweighted observations were initially included, consisting of 50 % ESRD patients and 50 % randomly selected patients without ESRD who underwent PCI. These observations were weighted to represent a national estimate of 106,830 patients. The mean age of the study population was 65 years, and 63 % of the patients were male. The ESRD group had a greater representation of minority groups compared to the control group. The in-hospital mortality rate was significantly higher in the ESRD group compared to the control group, with an odds ratio of 1.803 (95 % CI: 1.502 to 2.164; p-value of 0.0002). Additionally, the ESRD group had significantly higher healthcare costs and longer length of stay, with a mean difference of $47,618 (95 % CI: $42,701 to $52,534, p-value
CONCLUSION: In-hospital mortality, cost, and length of stay for patients undergoing PCI were found to be significantly greater in the ESRD group.
