this assessment is called Case-based Discussion
(CBD). In CSR/CBD the assessor is interested in the quality of the
trainee’s diagnostic reasoning, his/her rationale for choosing certain
actions and their awareness of differential diagnosis. In a typical
CSR/CBD assessment (Figure 12.3), the trainee selects several cases
for discussion and the assessor picks one for review. The assessor
asks the trainee to describe the case and asks clarifying questions.
Once the salient details of the case have been shared, the assessor
focuses on the trainee’s thinking and decision-making in relation
to selected aspects of the case such as investigative or therapeutic
strategy. CSR/CBD is designed to stimulate discussion about a case
so that the assessor can get a sense of the trainee’s knowledge,
reasoning and awareness of ethical issues. It is of particular value
in clinical specialties where understanding of laboratory techniques
and interpretation of results is crucial such as endocrinology, clinical
biochemistry and radiology
