When I worked inpatient --not that long ago-- we did get direct admits on the floor. They did have to stop at admitting for paperwork.
The hospital's policy, or lack thereof, regarding direct admits, or even admits from ER, for that mattter, created a lot of problems for the nursing staff. The only order required for the patient to be admitted was "Admit to service of Dr. Whoever." Patients would arrive in pain, hungry, vomiting, pooping, gasping, wheezing, with family in tow. If they came from ER, we had a diagnosis. If they were direct admits, we usually had nothing! We had to call or page the docs for orders, and sometimes didn't get orders for a couple of hours. I remember one time that it took the doc over six hours to respond! In the meantime, the poor patient was not being treated, and the family was going ballistic. Patients and families understandably found the statement, "I'm sorry, but I can't feed you, give you pain med, or anything else until I hear from your doctor. Yes, I'm just waiting for him/her to return my call(s)." This was especially disturbing when the patient came directly from the doctor's office, and could have hand-carried the orders with them!
I don't miss that place!
