All hospital related chaplains get a list daily who is of their faith and go directly to them. All private ministers - the patients own minister - goes in like any family member unless it’s critical care - then they check in with the clerk at the front desk in the main lobby - as only a limited amount of people are allowed in that section and the family makes sure he is accommodated with an opening to the patient.
Not only critical care. See what I mean? It would take forever to teach you anything.
