"Bad call"

My husband was taken into hospital yesterday after a Dr called to see him at home and made a decision to call an ambulance as his breathing was bad. He was lucky and got a bed straight away and many tests were carried out. I left him at 7pm I thought he was in for the night. Seemingly not at 12pm he was wheeled down to main entrance and left for a cab to take him home armed with a bag of pills and still in only his pjs. He was left there on his own no one around for best part of an hour waiting. Arrived home gasping for breath at 1am in a worst state than when he went in. Where has the care gone or does that go out the window once your bed is needed for the next patient. I was in hospital myself recently and thought things had improved but obviously not.
