A problem-solving method for "unprotocolised' therapy administration task in medicine

This paper describes a problem-solving method for modelling the 'unprotocol ised' treat ment administration task in medicine. We argue that there are m edical domains in which no well-established standard treatment protocols ex ist, and the physician has to decide on the therapy that is to be applied t o each patient, in function of a set of therapeutic objectives to be fulfil led. For this reason, we propose the modelling of this type of task adaptin g the generic class of problem resolution methods for design task, labelled as Propose-Critique-Modify (PCM). In this paper, we are presenting a model of expertise which has been developed using the basic modelling components of the CommonKADS methodology. (C) 1999 Elsevier Science B.V. All rights r eserved.
