In its present form, it doesn't clearly benefit either docs or patients. It is just more contrived techno-crap designed to make the public think something is being done about medical errors, handwriting, cost control. Or anything else the press, politicians & academics think needs fixing. In fact, NewCrop and Surescripts are walking away with patient & provider $$$ for providing mediocre service.
So now we have new sources of errors and inefficiencies,
not always obvious. And the cost benefits seem mostly for the third party payers. And there aren't any savings unless formulary matching is available. As mentioned above, it is often not.
