When students learn numbers: evaluation of a course in clinical decision-making

This paper describes the evaluation of an innovative course in clinical decision-making (CDM). A traditional course in neurology taught concurrently to the same group of students by the same teacher was used for comparison. The aim of the course was to introduce students to the basic concepts of CDM as an aid to rational decision-making. The end-point of the evaluation was their perception of the immediate clinical relevance of CDM. It was postulated that by seeing this relevance they would be more likely to change their decision-making behaviour than by simply learning factual content or principles. The evaluation used an ongoing formative approach, including ethnographic analysis, questionnaires, small group discussion and supportive feedback for the teacher. The ongoing evaluation of the course resulted in revisions with increasing relevance within the students' level of experience, changes in sequence of presentations and encouragement of active student participation. A pre-test showed that students had difficulty in the correct assessment of the validity of data and in the correct revision of opinion. Results of the evaluation indicated that the CDM course did not achieve its objective of making students aware of the immediate clinical relevance of CDM. Possible reasons for this include the lack of reinforcement from clinicians suitable for modelling and the context specific nature of the learning of thinking processes. For a CDM course to be successful, it may need to be taught within the context of specific clinical topics. It is suggested that the evaluation approach used here is a cost-effective method when considering innovations in the curriculum and useful for generating further questions for study.
