This thread had really shown the poor understanding the public have of the NHS, sadly.
Talking about needless prescription of over the counter medicine, ambulance transport, drunken A&E attendance, even travel health, all these are just a tiny drop in the ocean of the NHS costs.
I'll see it again, the cost that is seriously debilitating the NHS is diabetes. Preventable diabetes, but this is just ignored because recognising this fact is pointing the finger our ourselves, and no-one wants to do that.
The care for diabetes become an issue later in age, so the majority of posters here don't see any of it. They talk about the NHS from their experience, except that the experience of 20-50yo is not even 1/3rd of the cost of the NHS.
It's older age that is the draining the NHS, a vast majority a necessity, but again, it's the impact of diabetes that takes a toll in older age that is the biggest drain, so stop pointing the fingers at the system, at stuff that do need improvement but are only a needle in a stack of hay or starting question what YOU can do to improve your lifestyle so that we don't become the generation that will definitely finish off the NHS in 20 years time.
