I think fairlyflyer was trying to point out that every country will have there good and bad points. To label the whole medical system of any country down to one bad experience is probably a bit harsh.
I've been to the UK and when the wife came across problems with the pregnancy, the NHS was very professional. In saying that, the baby was delivered in HK which was equally professional.
Unfortunately a previous post sounded more like a gripe than anything else, and i'm sure that person will have a negative thing to say about the whole moving to HK experience and it would be rather wise to listen to his/her words with a pinch of salt.
