Tracking development of clinical reasoning ability across five medical schools using a progress test.

Purpose Little is known about the acquisition of clinical reasoning skills in medical school, the development of clinical reasoning over the medical curriculum as a whole, and the impact of various curricular methodologies on these skills. This study investigated (1) whether there are differences in clinical reasoning skills between learners at different years of medical school, and (2) whether there are differences in performance between students at schools with various curricular methodologies. Method Students (n 2,394) who had completed zero to three years of medical school at five U.S. medical schools participated in a cross-sectional study in 2008. Students took the same diagnostic pattern recognition (DPR) and clinical data interpretation (CDI) tests. Percent correct scores were used to determine performance differences. Data from all schools and students at all levels were aggregated for further analysis. Results Student performance increased substantially as a result of each year of training. Gains in DPR and CDI performance during the third year of medical school were not as great as in previous years across the five schools. CDI performance and performance gains were lower than DPR performance and gains. Performance gains attributable to training at each of the participating medical schools were more similar than different.
