I can only offer really negative experiences. They are so stretched that they are not providing the care that is needed, with an agenda to get you out of there.
With our A&E, there is sometimes just one doctor to cover the whole intake, extended assessment and observation ward. People sitting in bays for hours just waiting for discharge, and with the pharmacy closing at 5, they could have to wait overnight for medicines to allow that.
My mother eventually died after going in with a simple UTI and put into obs overspill ward (and forgotten) without the doctor not understanding enough English to prescribe anti-biotics.
First time she was admitted there were beds but nobody to accept handover of the patients (being a bit stroppy, I cleaned a bay put mother into a bed, sending one paramedic to prep ambulance for departure while the other waited for handover; then demanding handover - they do not want to do this because it sets the clock ticking)
I was left sitting in a dark cold corridor with a head injury - by morning my DH got a wheelchair, took me to the GP for a checkover and patch up.
A recent post-op problem got me a 5hr wait, but rapid bloods when I was called, then back to waiting room to sit on the (rather dirty) floor. An elderly very frail lady was leaning on the wall after her bloods (I went and stole a wheelchair from the main hospital foyer wheeled it outside and back into A&E for her to sleep in)
