I don't know anybody who specifically works at that facility, but his wife is going to have to call to get updates. Don't expect a nurse to call her.

What I suggest is calling sometime between 1 PM and 4 PM to have the best shot at getting a hold of the nurse, and working with the nurse to schedule a time for a call with the doctor. Generally speaking if the doctor knows the wife needs to talk to them, they will call when they round on the patient. Usually this would be in the morning.

I wish I had some help for you, but want to wish your friend and his family well. Lifting prayers
