The EMR industry has a huge bureaucratic barrier to entry, which is why you don't see it technologically progressing at the rate of other industries.

The space is dominated by major players that have existed since the 1980's (Epic, Cerner, etc.), which also employ the technology of the same era (MUMPS, Caché, etc.).

If anyone is going to disrupt the EMR industry, it is going to be a bigger company that can sink the costs necessary to get up to speed for an entire HMO, and a couple HMO's willing to take the risk of piloting the software.
