An unsuccessful experience with computerized medical records in an academic medical center.

Computerized medical records systems are used in only a small percentage of U.S. health care facilities, despite predictions that they would be widely used. The authors here report on their experience with the Computer Stored Ambulatory Record (COSTAR), a computerized medical records system, installed at a large primary care clinic at a university medical center. Although some equipment and computer resources were provided by the medical center, ongoing operations were financed by clinic revenues. After four months, use of the system was terminated because clinic revenues could not cover operating costs. The operating costs accounted for 17 percent of the average charge for an office visit. The major component of the operating costs was personnel expenses for data entry.
