I went in with a fast AF, as a new symptom of my heart problem, ambulanced in as they were not happy to leave me home (I had tried to fix it with more beta blocker, didn't work but a good attempt anyway)...
Cutting a very long story short - I was left sat in my own piss, for almost 18 hours on an unsuitable surface (wheelchair user, needs pressure relieving seating/mattress - which they had, but in stores the other side of the site and no one on with the key), no assistance to toilet, no suitable food (diabetic, nothing appropriate and nothing with the carbs/sugar content listed), having a hypo with no way of getting help from a side room (still in A&E!) with no way to reach a call bell (not sure there even was one).
Ignored several times by nurses too busy discussing weddings and shopping, so the fact I had not had meds they thought I had had didn't register for hours, by which point the relevant cardiologist and pharmacist had gone home...
Finally after no one called my partner, he eventually showed up, to find me having a massive hypo, still sat in my own piss, and he brought my chair so after he found me some sugar (in my bag but helpfully placed where I couldn't get it!!) I could self discharge and collect my meds the following day.
The pressure sores I got from that took near 6 months to heal.
I won't be going again unless its 'you're going to die in the next five minutes unless you go' situation (which to be fair they didn't know wasn't the case last time).
Last time my sister ended up there (following heart surgery at another hospital), she was given the wrong meds, by a Dr who had absolutely not understood her immediate history or medication schedule - who then argued that he was right with her and two other drs and it took a WEEK to fix his errors, he's bloody lucky (as is she) he didn't kill her. He had to have it explained twice, the second time with her flashing her 'zipper' at him before he grasped she HAD had open heart surgery recently, he first assumed she was still waiting for it, then that she'd had it years ago! I don't think English was even his fifth or sixth language and reading comprehension non-existant + sleep deprivation and totally inadequate supervision.
