A new survey of physicians shows that as medical records, doctor's offices and hospitals go increasingly digital, Apple's iPad and iPhone are the top choices for interacting with health records and staff. Demand for more medically-centric apps is increasing, with 83 percent of the physicians surveyed saying they plan to take more advantage of Electronic Health Records (EHRs) on mobile devices to update information, order medication and analyze lab results as more apps come to market that can handle those functions.
