Abstract:
DIOGENE 1 has been a mainframe-based centralised HIS with a star network of communication
operating on a daily basis with 120 nursing ward units since 1978. Together the limited
and costly growth capabilities of such a system with its extreme difficulty in cooperating
jointly with other heterogeneous medical systems, with the need for faster networking
expansions, led to the new design of a distributed architecture called DIOGENE 2.
In 1989, a migration process between DIOGENE 1 and DIOGENE 2 was initiated and is
now on the verge of being achieved. During the time of this new expansion of the HIS,
it has been easy to cooperate with the decentralisation process of the new hospital
organisation as well facilitating the integration of new functionalities like i.e.
new WIS architectture, medical office patient histories, integration based upon PCs
with UNIX based client/server platforms. That approach combines the handling of paragraphs
structured patient records with the use of medical natural language processing and
semi-automatic encoding as well. Amongst these new functionalities the P ACS are associated
with image manipulation platforms called OSIRIS for X-Ray images as well as other
tools devoted to molecula biology and genetics up to the ExPASy server on Internet
using WWW Mosaic which is accessible from all over the world. The distributed architectture
appears well suited not only for the integration of these new functionalities but
to keep them growing as smoothly as possible.
