1 From the Departments of Radiological Sciences (J.D.N.D., U.S., B.Y.D., G.H.T., H.K.), Computer Science (D.B.J.), and Family Medicine (R.J.), University of California, Los Angeles, 924 Westwood Blvd, Suite 420, Los Angeles, CA 90024; the Department of Radiology, Children's Hospital and Regional Medical Center, University of Washington, Seattle (R.K.T.); and the Harris Family Medical Center, Melbourne, Fla (S.B.). Recipient of a Certificate of Merit award for an infoRAD exhibit at the 1998 RSNA scientific assembly. Received March 1, 1999; revision requested April 28; final revision received October 11; accepted October 21. Supported by grant RO1 CA 39063 from the National Cancer Institute. Address correspondence to J.D.N.D. (e-mail: dondi@itmedicine.net).

An effective, integrated telemedicine system has been developed that allows (a) teleconsultation between local primary health care providers (primary care physicians and general radiologists) and remote imaging subspecialists and (b) active patient participation related to his or her medical condition and patient education. The initial stage of system development was a traditional teleradiology consultation service between general radiologists and specialists; this established system was expanded to include primary care physicians and patients. The system was developed by using a well-defined process model, resulting in three integrated modules: a patient module, a primary health care provider module, and a specialist module. A middle agent layer enables tailoring and customization of the modules for each specific user type. Implementation by using Java and the Common Object Request Broker Architecture standard facilitates platform independence and interoperability. The system supports (a) teleconsultation between a local primary health care provider and an imaging subspecialist regardless of geographic location and (b) patient education and online scheduling. The developed system can potentially form a foundation for an enterprise-wide health care delivery system. In such a system, the role of radiologist specialists is enhanced from that of a diagnostician to the management of a patient's process of care.
