6.1% critical. These patients will die without very extensive hospital care.
A study of critical patient outcomes at a Wuhan hospital stated that 67% of critical patients in the study died. If those patients required mechanical ventilation it went up to 80%. And no one in the highest age groups on ventilation survived. The survives were all in younger age groups.
So the statement that 'These patients will die without very extensive hospital care' is a bit misleading in the sense that if a patient was very old if they became critical it didn't matter how much intervention there was, they were virtually certain to not recover.
Which begs the ethical question of when is it best to let patients die with dignity rather than prolonging their suffering by keeping them alive artificially.
This is a question that unfortunately we probably are going to have to face up to sooner rather than later under the circumstances.
The fragility of life over a certain age when people get even mild illness is something we don't like to talk about because it makes us confront our own mortality and the fact there is a finite limit to what medical intervention can achieve.
This isn't pleasant but the fact we have a population which is more aged than ever before means we have many more who are particularly vulnerable to what ultimately are natural causes.
