Having some minimal experience working with electronic medical record (EMR) systems, this study doesn't surprise me. It's a market in a very nascent state, and one dealing with tremendous complexity. I've been in the position to debunk some common misconceptions about EMR's, such as the notion that they're just scanned images of paper documents.
One they get things right, though, watch out. The EMR will one day have the same sort of impact on medicine that CAD/CAM software has had on design and manufacturing. More so, even.
