Adapting undergraduate preclinical courses to changes in clinical applications.

The availability of new technologic tools has greatly changed differential diagnosis. To assess the importance of these tools in current clinical practice, the authors determined the frequencies of use of new imaging methods in diagnosis, staging, and follow-up in 71 oncology cases. The new methods were found to have replaced traditional diagnostic procedures to a substantial extent. To familiarize medical students with the new techniques, lectures on sectional anatomy given by radiologists were integrated into traditional anatomy courses for a group of 50 students. Two years later, after their initial exposure to clinical practice, the 42 students remaining in the group answered a questionnaire regarding the usefulness of the sectional anatomy segment of their anatomy training. Of these 42 students, 14 rated the sectional anatomy exposure "very helpful" to comprehension in the clinical internship and 21 rated it "helpful." The students suggested that the program be reinforced by an integrated textbook. This preliminary study suggests that basic preclinical courses should be modulated to reflect new methods that come into routine use in clinical practice.
