Patients undergoing long-term dialysis were more than five times likelier to be infected with COVID-19 and nearly four times as likely to die than the general population, suggesting that they should be prioritized for vaccination, according to a Canadian study published today in CMAJ.In the study, researchers from the Ontario Renal Network at Western University in London, Ontario, compared disease characteristics and death rate between long-term dialysis patients with and without COVID-19 infection using linked datasets from Mar 12 to Aug 20, 2020.Of 12,501 dialysis patients, 187 (1.5%) were diagnosed as having COVID-19; 62.6% of them were hospitalized, 19.8% required intensive care, 15% received mechanical ventilation, and 28.3% died.
