I don't write contracts but my current day job is "Information Technology 'stuff'" at a company that is related to this field.
While I couldn't talk about and have made no effort to remember the (obviously confidential) details of conversations I've overheard, I have heard enough to know the general trend in this area.
There are two main components to worry about here.
1) Cost of the procedure. Currently medical trials are activities by the 'drug company', except for things that a patient in that position 'should' need anyway. If academia were developing (at testing!) the new medicine/techniques then the 'medical research' system would need to cover it. Obviously this is more likely to work out with a 'single payer' system.
2) Risks. The unknown is risky. It can lead to worse outcomes and increased expenses. Similar to point 1, there would need to be coverage of this built in as well. As a special addition to point 1 it would also involve fixing 'malpractice' lawsuits and the like.
I think that if I were ever to be involved in a malpractice circumstance what I would actually want would be:
* If the involved practitioners are //at fault// them to be barred from the profession and related fields.
* If anyone lied or covered up information that would have lead to a better outcome them to go to jail.
* The absolute best effort at fixing and/or treating the resulting issue to be provided (a single payer system just should).
