Ah! Now you've raised a point, Maiyakat...
But first, many thanks for the responses on this thread, they are very illuminating and esp Nat6999's advice on how to prevent UTIs, I will look into that for my Dad...
He had also got thrush (er, non-STI variety, he's not at 93 been secretly clambering out of the window for secret sessions 'I'd be very impressed if he had,' said my doctor) and the meds cleared that up too.
I have a savagely cynical attitude to the State's treatment of the elderly based on my mothers' care in about seven Surrey care homes and not assauged by what went on during Covid. And yep, cost at some point is a thing they look at. And, picking up on Maiyakat's point - if an elderly person goes into hospital and dies, it's not really anyone's problem bar that of the family, esp if the patient is over a certain age. It saves money on prescriptions, pensions plus the State gets a hefty inheritance tax. The fact that free antibiotics and pension is a big perk means it often doesn't occur to a family that it really isn't free for the State.
This is why I wanted to have an idea of how much stuff costs. Dad also gets Gluten-free bread. Nice! But frankly we can pay for that, should we really be getting that in for him? And compare this to anyone going into a home in Surrey, you're looking at £1.5 k a week. A week! The numbers just don't correlate.
I think that was what went on with the kid Billy Caldwell a few years back who had epilepsy - seems to me the NHS simply didn't want to fund his medication. If he died of a fit, it wasn't their problem. His mother would be posting his picture on Facebook as if to say, hey, he's not one of these kids on life support! She had to go abroad to get the meds, then got arrested coming back with them - or rather she gave herself up, and they were confiscated. I think they wanted her to get arrested so they could criminalise her. It was an awful chess game they were both playing, and they messed her about big time. Again, had he died of a fit thru not having the drugs, you can't say it's legally anyone's fault. The drugs were illegal - but anyone can get hold of illegal drugs to fund a party lifestyle of course. But the State gets very interested when you're 'on its list' you can take it from me.
Anyway, many thanks for these responses!
Thankfully Dad is not reliant on the liquid antibiotics for the most part, he is okay with small capsules.
