Very few companies, for-profit or otherwise, keep gobs of machinery on hand "just in case". It's expensive, not only the machinery, but the space to store it, maintain it while not in use, replace it when it ages out, and so on. It's also exceedingly rare to need it.
Hospitals also have limited resources in terms of IT staff. It's not a Azure army of operations staff that can rush out to every endpoint and click buttons.
When I was in helpdesk eons ago, I was "responsible" for roughly 300 - 400 endpoints, plus a handful of servers. As were all of the other helldesk techs. If something like this happened, there's simply not enough hands to go around as fast as everyone would like.
What I meant when I said reinstall the PCs was to reinstall the critical computers necessary for operation of medical machinery to make basic and still mostly manual/paper based operation possible, not every computer they have there. I really don't think they have hundreds of computers necessary for operations of MRIs and other machines.
