The EMR usability problem is tough and expensive to solve. Medicine is extremely complex and every specialty has a different workflow. Build a system that pediatricians love and oncologists will hate it, or vice versa. Instead of just complaining that Epic developers are doing a crap job, what specifically should they change?

The communications and integration problem is gradually improving. In order to comply with government mandates, most EMRs now include HL7 interfaces that comply reasonably well with current standards and no longer charge extra for that feature. But every system still has a different internal data model so something is always lost in translation.
