It is becoming increasingly common for hospitals to offer physicians access to their electronic medical record (EMR) systems. Because of Stark antikickback laws, hospitals are required to charge physicians "fair market value" for the technology. Yet, the definition of what constitutes "fair market value," is still quite vague. Evanston Northwestern Health Care in Evanston, Illinois is planning to offer its Epic software system to physicians for a one-time fee of $12,000. This fee is what Epic charges the hospital for adding an additional user to the system. San Francisco-based Sutter Health is another hospital system selling its EMR to physicians. Sutter has not yet determined how much it will charge physicians for the program. However, Sutter is also offering free software to physicians who already have their own EMR systems that will allow them to interface with Sutter's program. Another hospital group, Washington, D.C.-based MedStar Health, is negotiating deals with vendors to either sell or lease their ambulatory EMRs at substantial discounts for its affiliated physicians. MedStar officials say that they will be doing physicians a great service in at least narrowing down their list of potential vendors.
