What proportion of COVID-19 patients admitted to intensive care may suffer from kidney failure requiring dialysis?

Infection with COVID-19 has been associated with various complications, including kidney injury and failure in some patients. Research indicates that a significant proportion of patients admitted to intensive care units (ICUs) experience acute kidney injury (AKI), and some require dialysis as a treatment.

The option indicating "up to half" reflects studies showing that around 50% of COVID-19 patients in ICUs may suffer from kidney complications severe enough to necessitate dialysis. This aligns with clinical observations and data collected during the pandemic, where acute kidney injury rates in critically ill patients were notably high.

Understanding the connection between severe respiratory illness caused by COVID-19 and resultant kidney complications is crucial, as it highlights the multi-organ impact of the virus and the need for close monitoring of renal function in patients with severe cases.
