Intranet technology in hospital information systems.

The clinical information system architecture at the Columbia-Presbyterian Medical Center in New York is being incorporated into an intranet using Internet and World Wide Web protocols. The result is an Enterprise-Wide Web which provides more flexibility for access to specific patient information and general medical knowledge. Critical aspects of the architecture include a central data repository and a vocabulary server. The new architecture provides ways of displaying patient information in summary, graphical, and multimedia forms. Using customized links called Infobuttons, we provide access to on-line information resources available on the World Wide Web. Our experience to date has raised a number of interesting issues about the use of this technology for health care systems.

Evolution of the Intranet in the University Hospital of Gent.

The explosive development of the internet in recent years has lead to the production of massive collections of web-based tools and development know-how. Implementing an Intranet solution within a health care environment offers tremendous advantages for internal information management, distribution and collaborative computing. Easy adaptability, scalability and the low development cost allow easy integration into existing health care structures. A key aspect of the UZ Gent Intranet is its transparent interaction with the currently implemented HIS thus providing an open gateway to the future.

Clinical applications of Intranet-technology.

Several areas of HTML-applications using intranet-technology are presented, which are in routine use in our hospital: CBT for nurses and medical students, drug information, electronic literature retrieval systems and laboratory information systems. The basic concept is an integration of commercial databases and local information. All applications are hardware-independent with the same user-interface and all use client-server-technology. By a central update it is ensured that everybody gets the most recent information. As a result of these efforts synergy has developed. The training of the medical staff is supported which helps to improve the care of the patients.

The role of communication servers in the architecture of healthcare information systems.

Communication between departmental subsystems within a hospital information system (HIS) is more and more supported by dedicated communication servers (CS). One of the main advantages is a centralized and standardized flow of information. Beside this "classic" approach a communication server may be embedded on at least two other hierarchical levels in the architecture of healthcare information systems: in an organizational unit within a hospital (subsystem) but also in large scale healthcare information systems covering aspects of communication between the involved external healthcare providers.
