The Monash University-led research analysed data from 76 ICUs across the country treating 149 suspected Covid-19 patients since March 14.

Preliminary data from this ongoing research showed men were twice as likely to be admitted (67 percent of cases) to ICU than women (31 percent), while people over 60-years-old made up 69 percent of ICU patients.

Co-leader of the research, Professor Andrew Udy from Monash University, told Xinhua the initial results matched up with reports from other countries that a greater number of men had been admitted to ICU with confirmed Covid-19 than women.

"This is the first time we have data outlining the number of Covid-19 patients requiring ICU, the duration of their care, the type of treatments they're receiving, and the number that are surviving," Udy said.

"From a broad national perspective, this data gives us important insights into the type of therapy, care, and medical intervention our sickest Covid-19 patients need," Udy said.
