Sounds like you already understand it pretty well. People like local services, localisation is always popular as a concept for the NHS, being able to get any treatment down the road from where you live. But from efficiency and effective care perspective it's rubbish. You are better off having a few national centres of excellence, where people with specialist conditions can go and get really excellent care from teams that deal with their condition all the time, and who can afford all the latest equipment etc. than you are having every hospital being generalist and average at everything.
