Abstract [en]
In the development of a clinical decision-support system for the domain of cognitive disorders, the domain knowledge was analysed. Certain qualitative aspects of the knowledge were of special interest, which, when taken into account, allow the system to be used as the intended cognitive tool which mediates learning, reasoning and decision-making in a clinical setting. The aspects concerned granularity, complexity and ambiguity in the evidence. Motives for how these are managed in the system development are given. The domain knowledge was integrated in a model of the clinical reasoning process, which was valuated by interviewing and observing domain experts and primary care physicians while using the prototype system with the model integrated. The resulting support given by the system throughout the reasoning process includes the distinction between typical and atypical cases of patients, an interpretation of the evidence concerning a patient within different contexts of clinical guidelines, thus eliciting ambiguities and their sources. The system also provides different level of support depending on the user’s need and experience.
