The KUSIVAR project
| The KUSIVAR project was a part of
KUSIN-MED, a Nordic research program dealing with the
application of medical knowledge-based systems. KUSIVAR
was a collaborative research project involving the
Medical Intensive Care Unit, Södersjukhuset, Siemens
Elema AB, Unisys AB and the Division of Medical
Informatics, Linköping University. This collaboration
resulted in a knowledge-based decision-support system
called VentEx. The VentEx system has been built to
support ventilator therapy management using
knowledge-based system technology. Development started
with an early prototype system called KUSIVAR that dealt
with knowledge representation and knowledge acquisition
research using the Knowledge Engineering Environment
(KEE) from Intellicorp. A domain specific tool called
KAVE (see figure below) was later developed to facilitate
the knowledge acquisition process. Then a PC-based
on-line system (VentEx) was built as an integrated
knowledge-based system in the clinical environment.
Because it was not possible to use KEE at a reasonable
cost (due to the expensive hardware and software),
Nexpert Object from Neuron Data was used in the real
environment. The evaluation of the system indicate the
usefulness of KAVE, and there was a strong consensus
between the doctors and VentEx with respect to a
"gold" standard. The project was carried out with collaboration among domain experts, clinical engineers and knowledge engineers. A group of domain experts (5-6) were involved in tuning the knowledge base. The main knowledge acquisition process took about 3 years including the development of KAVE. The figure below shows the whole process of the KUSIVAR project.
