"Parents who think it is more important for them to be close to their children than to get a proper outcome."
That sums up what is a very simple equation pretty neatly. This whole issue has arisen because experts - surgeons and physicians - know that children are more likely to survive complex heart surgery if it is performed by specialist teams with experience of the procedures involved.
The number of operations means that it isn't viable to have experienced teams in every major hospital, so the proposal was for 'centres of excellence' to be established, where children would have a much better chance of a successful outcome.
Frankly it's a no-brainer, and I cannot understand why so many people seem to be having so much difficulty in grasping the point.
