To transfer a patient you must have an accepting doctor and a bed available. That’s fine, but what if you are the biggest hospital in the area? If you are full, the other hospitals are too. In fact, they are bugging you for a bed for their sick patients.

People think beds and ventilators and nurses just pop out of thin air. Things have been like this for a long time. We’re only just now talking about it because now we have to.
