PURPOSE: To evaluate mortality risk of CKD patients infected with COVID-19, and assess shared characteristics associated with health disparities in CKD outcome.

METHODS: We extracted the data from a case series of 7624 patients presented at Mount Sinai Health System, in New York for testing between 3/28/2020 and 4/16/2020. De-identified patient data set is being produced by the Scientific Computing department and made available to the Mount Sinai research community at the following website: .

RESULTS: Of 7624 COVID-19 patients, 7.8% (n = 597) had CKD on hospital admission, and 11.2% (n = 856) died of COVID-19 infection. CKD patients were older, more likely to have diabetes, hypertension, and chronic obstructive pulmonary disease (COPD), were current or former smokers, had a longer time to discharge, and had worse survival compared to non-CKD patients (p < 0.05). COVID-19 mortality rate was significantly higher in CKD patients (23.1% vs 10.2%) with a 1.51 greater odds of dying (95% CI: 1.19-1.90). Controlling for demographic, behavioral, and clinical covariates, the logistic regression analysis showed significant and consistent effects of CKD, older age, male gender, and hypertension with mortality (p < 0.05).

CONCLUSION: CKD was a significant independent predictor of COVID-19 mortality, along with older age, male gender, and hypertension. Future research will investigate the effects of COVID-19 on long-term renal function.
