You should be able to page her doctor through a physicain exchange at the hosptial. It may be another doctor that's "on-call", but you should be able to page SOMEONE.
A fever is actually a good sign - her body is responding appropriately to whatever infection she's fighting. Unless she seems lethargic and won't drink fluids, I would avoid the ER.
