The UK is planning to re-train other medical staff to deal with respiratory illness. I think that probably includes things like psychologists, etc. who have medical experience and can quickly be brought up to speed. Might be something like that.
Uh, psychologists have zero medical training or experience - maybe they could explain the patients their respiratory failure is a symptom of insecure attachment patterns.
If you mean psychiatrists, there aren't that many of them to move the needle.
