A new study by the Fund's Anne-Marie J. Audet, M.D., David Squires, and Michelle M. Doty, confirms that more U.S. physician practices are embracing health information technology (HIT). Between 2009 and 2012, adoption of electronic medical records by primary care physicians grew by half, from 46 percent to 69 percent. Moreover, a majority of physicians are now using core HIT functions such as e-prescribing, electronic ordering of labs, and certain types of clinical decision support. The study, which also reported on gaps in HIT adoption and suggested ways to close them, was published in a special issue of Health Services Research edited by Weill Cornell Medical College's Rainu Kaushal, M.D., and The Commonwealth Fund's David Blumenthal, M.D.
