This is true. I am a (polite) squeaky wheel, and I can navigate these systems better than average. I'm sure others would be sitting here saying, oh it will come, they know best, I don't want to rock the boat. So it must be more frustrating for them.
This particular system seems screwed up. There is the clinical "get her home asap" vs the administrative "have we ticked all the boxes" and they don't meet.
DH and I have decided that if Im in hospital again and it's after 5pm, I'm staying in, particularly as the lack of a follow-up appointment soc years ago happened when I was discharged after working hours and the ward clerk had gone home.
