Clinical features and risk factors of the mortality in hemodialysis patients infected with SARS-CoV-2

Objective To investigate the clinical features of patients with maintenance hemodialysis(MHD)infected with SARS-CoV-2 and analyze the risk factors of death after SARS-CoV-2 infection,and to provide clinical data for early detection of critically ill patients and timely intervention.Methods It was a cross-sectional investigation study.MHDpatients in the hemodialysis centersof four tertiaryhospitals with geographical representation in Shanxi province from December 1,2022 to January 31,2023 were enrolled,and the demographic data,dialysis-related indicators,laboratory test results and clinical features of SARS-CoV-2 infection were collected by distributing the questionnaires on SARS-CoV-2 infection,and consulting the hospital medical record system and the outpatient hemodialysis information system.SARS-CoV-2-infected patients were divided into survival group and death group according to whether all-cause death occurred and the differences of baseline data between the two groups were compared.Multivariate logistic regression analysis method was used to analyze the risk factors of mortality in MHD patients infected with SARS-CoV-2.
