MO820: Comparison of All-Cause-Mortality Before and After COVID-19 Vaccination in a Hemodialysis Center

Abstract

BACKGROUND AND AIMSControl of COVID-19 outbreaks in hemodialysis wards has been a great challenge for dialysis ward managers during the pandemic. Besides, frequent patient education and provision of sanitation and prevention protocols, COVID-19 vaccination brought light to systematic control of COVID mortality. The aim of this study was to assess the effect of the COVID-19 vaccination on all-cause mortality in our hemodialysis ward.METHODCrude and age-adjusted mortality rates of 2-time frames, i.e. 6 July–6 December 2020 and the same period in 2021 (before and four weeks after full vaccination against COVID-19 with Sinopharm (Beijing): BBIBP-CorV) were compared. The data were processed with SPSS software version 26.RESULTSFrom 6 July to 6 December 2020, the crude all-cause-morality rate of our hemodialysis center was 9.12% (23 out of 252 patients). Between 6 July 2021 and 5 December 2021, the crude all-cause-morality rate was 6.74% (17 out of 252 patients). The same result was found after age adjustment of the morality rates.CONCLUSIONCOVID-19 vaccination reduced the all-cause mortality in our hemodialysis ward, as reported in the general population. Further multi-center studies are encouraged to study the effect of vaccination on the number of severe cases and the rate of hospitalization in this group of patients.
