MOD PARENT UP!
This is at the heart of the whole issue. Medical Data is hard and that leads to crappy implementations, unintuitive UI, less desire for docs to use it yada yada...
Although I disagree that one needs to represent everything "symbolically" there are several EMRs with free-text note fields and post-process the notes with NLP for meaningful secondary uses. Yes NLP is not perfect but things are getting much smarter and better.
