double entry (bad/missing interfaces) + bad templates = death for an EMR
I'm personally skeptical of how we are doing EMR implementation anyway. Hospitals and Dr's offices are sucking them up right and left, but they all have radically different data models.
I should be able to hand my NextGen-based doctor's office a USB drive on my keyring and offload my personal medical record. Then, if I present in an ER 1,000 miles away, I should be able to hand them my drive and them upload me into Cerner, McKesson, IDX, etc. etc. Then when the episode is over, I should be able to update my drive and take it back to my Dr.'s office to upload the updated information.
The right answer would be to harmonize at least some aspects of the data models used and *then* push for mass adoption across hospitals and dr's offices. EMR's clearly have local benefits as well, but we're really missing big picture if we don't focus on portability from the start.
