Direct knowledge from people who experienced it.

In one region, a major hospital is;

1. anything minor like you have a fever or cold or whatever they send you home, maybe give meds.
2. anything urgent like heart attacks they send to one of the biggest hospitals in a different region.
3. anything important but not urgent like broken bones, they redirect to another major hospital.

So if urgent, important, and minor issues are all being sent out of these hospitals, I am not sure what they do.

Since so many doctors have dropped dead maybe nurses have also died???

Edit: keep in mind, a region is basically the size of some US states. So it would be like shipping people out of state for heart attacks. They spent all the money building these hospitals and are now not using them.
