Abstract
Information about the patient‘s health status and about medical problems in general,
play an important role in stratifying a patient population for quality assurance of
intensive care. A terminological system which supports both the description of health
problems for daily care practice and the aggregation of diagnostic information for
evaluative research, is desirable for description of the patient population. This
study describes the engineering of an ontology that facilitates a terminological system
for intensive care diagnoses. We analyzed the criteria for such an ontology and evaluated
existing terminological systems according to these criteria. The analysis shows that
none of the existing terminological systems completely satisfies all our criteria.
We describe choices regarding design, content and representation of a new ontology
on which an adequate terminological system is based. The proposed ontology is characterized
by the explicit and formal representation of the domain model, the metaspecification
of its concepts, the vocabulary to define concepts and the nomenclature to support
the composition of new concepts.
