COVID ICU patients with acute kidney injury at higher risk for deathA small observational study presented over the weekend at the online Euroanaesthesia conference suggests that, of COVID-19 patients admitted to the intensive care unit (ICU), those with acute kidney injury (AKI) are more likely to die in the hospital than those with a history of kidney disease.According to a press release from study sponsor, The European Society of Anaesthesiology and Intensive care (ESAIC), the study also showed that dialysis doesn't appreciably increase the chances of survival.Austrian researchers retrospectively studied all 129 patients hospitalized with COVID-19 at two ICUs in Vienna from Sep 1, 2020, to Feb 15, 2021.
