my private GP is so helpful, always willing to look something up or phone a colleague if he can't be sure of the answer to a question. He makes sensible recommendations that really help, prescribes the most effective drug, and is willing to investigate things that the NHS would shrug off. Obviously, I'm paying and he has more time, but it does show what things could be like.
My Gp is like that, and I've never been refused investigation for me or my dc even when the chance of something is small, and the cost high. I've even had home visits suggested by them, after their hours of work. NHS isn't doing too badly.
And if we start looking at the HNS, let me give the example of my dd2. She was born without an arm.
The NHS has provided us with 1-2 prosthesis from 6 months old, OT appointments, extra gadgets she's needs, and all sort of other things.
The statistic I was given by someone in the US is that there, the condition would not generally be covered under insurance after they were born because it was a "pre-existing condition", on average parents have paid out over $200K on prosthesis and treatment by the time the dc is 18yo. Frightening.
