None of the examples I gave would be helped with increasing the number of doctors etc., except some emergency situations (in others, a finite number of doctors will be able to show up). As well as snowwrestler's point that the number of handoffs must be minimized, must be traded off with how long each doctor works.

I don't an practical means to obtain "actual evidence", it would require incredibly intrusive tracking of the careers of a bunch of doctors, and deciding the why of adverse outcomes is frequently going to be subjective.

I.e. was it the doctor or the patient? Which patients were more likely to have a bad outcome because of genetics or past history? The subject of "compliance" is sobering, sure you can prescribe a wonder drug, but you can't make the patient take it (aside from some TB regimens where compliance in taking a nasty multi-drug cocktail for 18 month or thereabouts is enforced).
