This paper reports on a study that examines physicians' understanding of concepts and decision making in problems pertaining to @entity1007 and @entity301 ( @entity301 ). The study was carried out in two phases: (1) a simulated clinical interview in which two clinical problems were presented and (2) a session in which subjects responded to a series of questions. The questions were related to the analysis of risk factors, diagnostic criteria (DC) for determining elevated lipid values, and differential diagnosis for @entity4977 . The subjects included 12 family practitioners who were randomly selected from a continuing medical education program at McGill University. The results indicate that all subjects exhibited gaps in their understanding of domain concepts. In particular, most physicians demonstrated a lack of knowledge concerning the primary @entity74 that contribute to @entity301 , as well as deficiencies in understanding the secondary causes of @entity1007 . The majority of subjects tended to overestimate the lipid value intervals for determining @entity1 at high risk. Physicians had no difficulty diagnosing the first @entity1 problem of @entity753 , but failed to identify the problem of elevated lipids secondary to @entity1375 . We observed a dissociation between subjects' conceptual understanding and their application of knowledge in solving @entity1 problems. The implications of this work are discussed in terms of the cognitive dimensions of technologies for supporting learning and evidence-based decision making.
