Just from a personal view, I have a wheelchair-bound friend who - due to bad assessments and no provision of aids at home had a fall. This lead to a grade 4 ulcer which needed a month in hospital where she nearly died because they managed to block the catheter they inserted and then not realise why she was going into shock. If folk think I am a bigmouth here, they haven't seen me when I am cross. That took nearly a week to clear. But as the chipper senior doctor pointed out "we caught it in time - at least she didn't die".
After that excitement she was assaulted by another patient in the same ward complex when his 24/7 nurse/minder had to pop to the loo. Apparently that time I was very much in the wrong to have photographed the bruises and called the police (who are permanent duty, there).
Obviously that delayed discharge, allowed her to get Covid. At this stage of the game I would have suggested she sue if she hadn't.
Move on to over 2 years later and the wound hasn't healed. The surgeons prescription is alternate day visits by the district nurses. But they don't do weekends. Apparently there is a shortage. However over the past 2 years my friend has counted over 40 different nurses - none of whom is from a different trust - plus (thank goodness) quite a few students. The amount of creams, sprays bandages, vacuum pumps, dressings and sundries has been incomprehensible.
That's one singular experience. If you multiply that up and down the country - needless injuries and diseases because of a lack of fundamental care from the start then you'll understand why I am actually grateful to be old and closer to the grave. Not that I have any faith the NHS could find it even with a miners lamp and pickaxe.
