"Discharged in a taxi"

My friend was discharged from Borders General Hospital tonight in a taxi rather than ambulance. She had to hop up a long drive way then up 3 steps on her bruised leg and had to put weight on her broken leg. Prior to discharge I discussed my friends needs with OT staff and asked her to be brought to my house by ambulance and a chair was necessary. Proper assessment was not completed and the staff member I spoke to on the ward agreed that the taxi should not have been used.
