Abstract 16971: Unraveling the Burden of Cerebrovascular Disease: Exploring the Role of Peripheral Vascular Disease and Kidney Transplant in End-Stage Renal Disease Hospitalization Rates (Insights From the National Inpatient Sample, 2005 to 2019)

Abstract

Background: Patients with end-stage renal disease (ESRD) face a higher risk of cerebrovascular disease, but the impact of peripheral vascular disease (PVD) and a kidney transplant (KiTx) on hospitalization rates for cerebrovascular conditions remains uncertain. This study aimed to investigate the rates of hospitalization for cerebrovascular disease in patients with ESRD, PVD, KiTx, or a combination. Methods: Using the National Inpatient Sample (NIS), 2,713,194 ESRD hospitalizations (2005-2019) were analyzed. We focused on two cerebrovascular conditions of interest: 1) cerebral infarction due to thrombosis, embolism, and occlusion (CITO) and 2) artery occlusion resulting in cerebral ischemia (AOSI). Comparative analysis utilized t-tests and odds ratios. Results: Among ESRD hospitalizations, 66,927 (2.47%) had KiTx, 63,411 (2.34%) had PVD, and 1,406 (0.05%) had both. Key findings included: 1) ESRD patients with PVD had higher odds of hospitalization for CITO (OR 1.33, CI 1.1-1.8, p=0.009) or AOSI (OR 2.63, CI 2.5-2.8, p<0.001) compared to those without PVD (Fig. 1AB); 2) ESRD patients hospitalized with CITO had higher odds of having KiTx and PVD compared to those without KiTx or PVD (OR 3.17, CI 1.0-9.3, p=0.035, Fig. 1AB); 3) ESRD patients with PVD had higher rates of being hospitalized with AOSI (7.29%) than those without AOSI (2.29%, p<0.001); 4) ESRD patients hospitalized with CITO had higher odds of having KiTx and PVD compared to those without KiTx or PVD (OR 3.17, CI 1.0-9.3, p=0.035, Fig. 1AB) and 5) ESRD patients hospitalized with AOSI demonstrated a higher rate of having KiTx and PVD (0.09%) compared to those without AOSI (0.05%, p=0.002). Conclusion: This nationwide analysis reveals that the presence of PVD and KiTx is associated with increased rates of hospitalization for cerebrovascular conditions. These findings underscore the importance of proactive management to mitigate the risk of cerebrovascular disease in this vulnerable patient population.
