ChatGPT in medical school: how successful is AI in progress testing?

Abstract

BACKGROUND: As generative artificial intelligence (AI), ChatGPT provides easy access to a wide range of information, including factual knowledge in the field of medicine. Given that knowledge acquisition is a basic determinant of physicians' performance, teaching and testing different levels of medical knowledge is a central task of medical schools. To measure the factual knowledge level of the ChatGPT responses, we compared the performance of ChatGPT with that of medical students in a progress test. METHODS: A total of 400 multiple-choice questions (MCQs) from the progress test in German-speaking countries were entered into ChatGPT's user interface to obtain the percentage of correctly answered questions. We calculated the correlations of the correctness of ChatGPT responses with behavior in terms of response time, word count, and difficulty of a progress test question. RESULTS: = 0.002). CONCLUSION: ChatGPT was able to correctly answer two-thirds of all MCQs at the German state licensing exam level in Progress Test Medicine and outperformed almost all medical students in years 1-3. The ChatGPT answers can be compared with the performance of medical students in the second half of their studies.
