Impact of COVID-19 on the mortality of dialysis patients and kidney transplant recipients during the Omicron fifth wave in Hong Kong

Collider bias, therefore, is a problem encountered when both the risk factor (haemodialysis) and the factor on the pathway to the outcome of interest (for instance, hospitalisation on the pathway to death) influence the mechanisms behind selection into a study sample population.6 7To overcome this b...

Summary:Collider bias, therefore, is a problem encountered when both the risk factor (haemodialysis) and the factor on the pathway to the outcome of interest (for instance, hospitalisation on the pathway to death) influence the mechanisms behind selection into a study sample population.6 7To overcome this bias, we determined the mortality of COVID-19 for all patients separately for each mode of renal replacement therapy (instead of the infected population). Mortality of patients on haemodialysis, peritoneal dialysis and with kidney transplantation Our results contrast with the previous observation of strikingly lower COVID-19 cases and deaths per population in Asian countries.4 Although we cannot exclude confounding factors such as frailty and age, the results of a high mortality burden among peritoneal dialysis patients should caution nephrologists who give advice about vaccination of dialysis patients.
