Nothing new with this revelation. It has been previously postulated.
Computerized patient records are unlikely to cut health care costs and may actually encourage doctors to order expensive tests more often, a study published on Monday concludes.
Medicynical Note: The cost of implementing a nationwide record system is considerable. Having such a system, however, will facilitate easier and more comprehensive analysis of health care and if we allow such use, perhaps some cost savings by directing care to the most effective economical modalities. That however is a big if.

Given that EMR systems disconnect practitioners from their patients and given that EMRs make test ordering easier and given that EMRs are really just bigger and smaller disconnected silos of disparate data, it is reasonable to conclude that an abundance of unneeded tests will be ordered.
Right now, with EMRs, even after Meaningful Use tax dollars have been poured out, doctors caring for the same patient are separated by complex systems that don’t talk to each other. Whether they are down the hall from one another or hundreds of miles apart, these doctors are really on different planets.
What we need is a global connectivity solution that doesn’t force practitioners to become clerks. If you are thinking about buying an EMR – DON’T. Search YouTube for the word SharEHR to find the highly profitable solution that solves all of the above and more.
