How about facilitating patient choice?
Limiting a patient's choice to a region or a certain group of doctors and hospitals puts at risk some patients' lives when those patients have a less common cancer (kidney, for instance) or a rare disease. What can be done so a patient does not have to choose between their family's financial ruin or the healthcare that could save/prolong their life?

A great point about regions. It is also important to look at age in certain regions. College towns and retirement communities will often have different health care needs. Rarity for a diagnosis or treatment may limit your choice in providers. IT is a difficult concern.
It is an excellent question. I'm not only worried about region, but locality. I happen to live in an area with several local hospitals, but go to a large hospital in my state capital for annual screening of a rare cancer. I don't want myself or family to be told that we need to go to the local hospital because it may cost less even though they aren't adequately equipped.

This is a good question -- for patients who may have an undiagnosed disease (because no one local can sort it out) or for patients who are diagnosed with a rare disease, it seems their geography ends up determining their fate.
