"Discharge Procedure"

My elderly father has incurable cancer. He also has problems with speech and swallowing. He was due to be discharged on Mon 14 July, on the 'Fast Track' procedure. He was informed that the discharge would be as early in the day as possible. However, I was given varying explanations why the discharge was delayed, eventually being told that an Ambulance would be available at 9 PM. This was clearly unsuitable for an elderly patient. Eventually he arrived home at 2 PM the following day. Although I have no complaint whatsoever at the treatment he received during his stay in hospital, I was extremely disturbed by the delays in allowing him to return home. Although it is too late to act in my own situation, I would like some kind of assurance that this will not occur in other, similar cases.
