I’m sorry to read all that you have gone through, OP.
I discharged myself after my last hospital stay (crash C Section) because the care I received was intolerable. The section was only necessary due to failings by staff in the lead up to my birth. I laboured for 129 hours and then almost lost my baby.
The post natal midwives wouldn’t even give me paracetamol because they said I should have packed it into my hospital bag. Like you, my catheter was full and I had no water for 12 hours.
I called my husband (I didn’t have him spend the night with me on the ward) and announced my intention as soon as he arrived. The nurse told me I had no legal right to do so, but I corrected her and she backed down.
I left with no antibiotics or DVT medication, although my parents picked it up for me from the hospital pharmacy the next day.
I haven’t been back to the hospital since and I have only attended GP practice for injections / check ups for my children. I have dealt with UTIs etc myself by buying antibiotics online. I tolerated a damaged kneecap without intervention. I am just too afraid to go back because I think I have been left with some degree of PTSD.
If anyone is even still reading my ramblings at this point - my experience of the NHS does not match what we are told to think, which is that all failings are at upper management level and all staff are tireless, thankless workhorses that will always go the extra mile. Just as in any industry, many many staff are simply not good. And, in fact, due to poor management, under funding and poor pay, I actually believe the NHS is attracting more and more of these types.
Furthermore, I have two nurse friends who have left the profession due to poor working environments - in the large part caused by the behaviours of their colleagues.
Part of fixing the NHS is acknowledging that many of our care givers are not adequately giving care because they do not want to.
I should add that I live 1 hour from my only “local” hospital and it languishes at the bottom of all league tables. It is on special measures, it has one of the highest birth intervention records in the country, and its natal services are some of the worst in England. I am fairly biased.
OP, I am not saying you should discharge yourself ofc. I just know the feeling of desperation. I empathise and I see you - individual cases of care in the NHS can be very, very bad.
One final note: I tried to complain via PALS, but when I received my medical notes, I was confused and surprised to find that my labour had been recorded as 45 mins, none of my many attempts to been seen via maternity triage had been logged and my baby had been recorded as breech. She was NEVER breech. She was trapped against my pelvis for many days and born blue, with the cord wrapped around her neck twice. My medical notes for this birth are completely incorrect - possibly someone else’s entirely. My complaint ran aground here. PALS felt I must be confused and had misremembered the facts.
