I was skeptical in the extreme when President Obama and other PPACA supporters claimed so much savings would come from electronic medical records. While in theory good, portable records might prevent some accidents and streamline care in certain emergency situations where there might not be time to take a full history, my actual experience with these systems did not give me much confidence. And it just sounded like yet another politician's silver bullet (HMO's were another such bullet 20 years ago).
There is no point in trying to automate the diagnostic process with an expert system AND retain the 12-year-trained doctor in the room. It strikes me as one or the other. Perhaps these systems are close to working fine and doctors can see themselves getting automated out of a job and this type of job is their last-ditch attempt to stop them. Or perhaps the systems really suck and add a lot of extra time and cost. It will be interesting when this has a chance to be fully studied.
