You may have a lot of resistance from the public too, who's going to have access to these records? Certainly you wouldn't want all these records stored all over the place in different systems which would mean one centralized system.
Having said that I just recently read an article about the VA which is using just such a system. They gave an example where the doctor can walk into the patients room, scan his wrist with the bar coded bracelet and have all his records pulled up immediately on a computer. He could then prescribe a drug which is sent right to the pharmacy. The drug arrives at the nurses station and they go into the room and scan the drug to make sure its right drug and correct dosage.
Certainly standardized computer records have an enormous benefit but the privacy and security of such a system is going to be questionable.
