There was a lot of chuckling over WellPoint's announcement that it will be partnering with IBM to use that company's Watson supercomputer for medical diagnoses.
The idea is that Watson will combine patient medical histories, tests, medical literature and (perhaps most important) clinical best practices to decide quickly what doctors should be doing.
It's not the only such deal in the market. Other tech companies have similar initiatives. AT&T calls its program ForHealth.
The idea in all these cases is the same, to take some measure of decision making out of the hands of doctors, and give insurers a rationale for denying expensive treatments when less costly ones are available.
Another term for this is comparative effectiveness. You look at what a lot of people have done in similar situations, what happened, then do what works best.
