Background
Patients with end-stage kidney disease (ESKD) are at higheran elevated risk of major thrombotic cardiovascular events (MTCVEs) and use moresubstantial healthcare resources than compared to patients without ESKD. There is limited information on costs following MTCVEs in patients with ESKD.
Methods
Cohorts of Medicare fee-for-service beneficiaries aged ≥66 years were created using data from the US Renal Data System (USRDS) for ESKD patients receiving in-center hemodialysis (HD) and a 20% sample of Medicare claims for non-ESKD patients. We included patients experiencing a new MTCVE (myocardial infarction, ischemic stroke, venous thromboembolism, or critical limb ischemia) between 2015-2018. Adjusted all-cause healthcare resource utilization (HCRU) and cost outcomes were assessed for 1 year following the index event.
Results
Table 1 and Figure 1 detail HCRU and costs, respectively, in the year following each type of MTCVE. Patients with ESKD had much higher rates of all-cause hospitalization than non-ESKD patients, with the largest magnitude of difference in patients with VTE. Rates of ICU admissions, inpatient days, emergency and outpatient encounters were significantly higher in ESKD patients even after demographic adjustment. Adjusted costs of care were higher in ESKD patients compared with non-ESKD patients across all encounter and MTCVE types, with some variation in costs attributable to specific encounter types.
Conclusion
In the year after an incident MTCVE, patients with ESKD had significantly higher all-cause HCRU and costs of care than non-ESKD patients who experienced the same type of MTCVE. These differences persisted even after adjustment.
