From legacy systems via client/server to web browser technology in hospital informatics in Finland.
The majority of hospital information system installations in Finland are based on a legacy technology from the U.S. Department of Veterans Affairs (VA). This paper presents an architecture and a tool set which provide a migration path from terminal-based to client/server technology, conserving much of the investments in existing applications. It is argued, though, that a new technological revolution is required in the form of extending the web browser/server technology to operational information systems in hospitals. A blueprint is presented for a further migration path from client/server to browser/server technology. The browser technology is regarded as a major challenge to hospital information systems in the next few years.
