Abstract
A prospective multiple choice question (MCQ) study developed to pre- and post-test fifth year medical students at the University of Queensland, was undertaken during 1990. We investigated whether there was a significant gain in their surgical knowledge base resulting from non-surgical rotations during the same year. We have previously reported a retrospective study suggesting that there was such a gain. Comparable clinical surgical pre- and post-tests were adapted from a fresh question bank, and were presented prospectively to four groups of fifth year medical students at the beginning and end of each 7 week General Surgical term. In contrast to our retrospective study, we found there was no significant increment in surgical knowledge using non-parametric Notched Box and Whisker Plot analysis of data. We conclude that this is either because students are compartmentalizing their factual knowledge base between one speciality and the next, or that indeed there is no benefit to Surgical knowledge base from prior non-surgical rotations. Assuming the former, a combined Medical and Surgical Objective Structured Clinical Examination (OSCE) at the end of the fourth year could serve to broaden the student's horizons and reduce factual dissociation during the fifth year.
