Abstract

Background: Large language models like ChatGPT have revolutionized the field of natural language processing with their capability to comprehend and generate textual content, showing great potential to play a role in medical education. This study aimed to quantitatively evaluate and comprehensively analysis the performance of ChatGPT on three types of national medical examinations in China, including National Medical Licensing Examination (NMLE), National Pharmacist Licensing Examination (NPLE), and National Nurse Licensing Examination (NNLE). Methods: We collected questions from Chinese NMLE, NPLE and NNLE from year 2017 to 2021. In NMLE and NPLE, each exam consists of 4 units, while in NNLE, each exam consists of 2 units. The questions with figures, tables or chemical structure were manually identified and excluded by clinician. We applied direct instruction strategy via multiple prompts to force ChatGPT to generate the clear answer with the capability to distinguish between single-choice and multiple-choice questions. Results: ChatGPT failed to pass the accuracy threshold of 0.6 in any of the three types of examinations over the five years. Specifically, in the NMLE, the highest recorded accuracy was 0.5467, which was attained in both 2018 and 2021. In the NPLE, the highest accuracy was 0.5599 in 2017. In the NNLE, the most impressive result was shown in 2017, with an accuracy of 0.5897, which is also the highest accuracy in our entire evaluation. ChatGPT’s performance showed no significant difference in different units, but significant difference in different question types. ChatGPT performed well in a range of subject areas, including clinical epidemiology, human parasitology, and dermatology, as well as in various medical topics such as molecules, health management and prevention, diagnosis and screening. Conclusions: These results indicate ChatGPT failed the NMLE, NPLE and NNLE in China, spanning from year 2017 to 2021. but show great potential of large language models in medical education. In the future high-quality medical data will be required to improve the performance.

TL;DR

ChatGPT (GPT-3.5) was evaluated on Chinese national licensing examinations for physicians, pharmacists, and nurses from 2017 to 2021 and failed to reach the 0.6 accuracy pass threshold in all three exam types. Its highest accuracy was 0.5897 on the 2017 National Nurse Licensing Examination, while performance varied by unit, question type, subject, and topic.

Key findings

  • ChatGPT failed to pass the 0.6 accuracy threshold in any of the three examinations over five years. Highest accuracies were 0.5467 for NMLE (2018 and 2021), 0.5599 for NPLE (2017), and 0.5897 for NNLE (2017); the lowest was 0.4356 for NPLE in 2019.
  • Average accuracy across the five years was 54.08% for NNLE, 53.05% for NMLE, and 49.02% for NPLE.
  • There was no significant difference across different units in NMLE, NPLE, or NNLE, but in NPLE ChatGPT performed significantly better on single-choice than multiple-choice questions (p < 0.0001).
  • In the 2021 NMLE, ChatGPT answered all questions correctly in clinical epidemiology, human parasitology, and dermatology, but had less than 0.5 correct in pathology, pathophysiology, public health regulations, physiology, and anatomy; no significant difference was found between case-based and non-case-based questions.

Methods

  • Questions were collected from Chinese NMLE, NPLE, and NNLE from 2017 to 2021. NMLE had 4 units of 150 questions (600 total), NPLE had 4 units of 120 questions (480 total), and NNLE had 2 units of 120 questions (240 total). Questions with figures, tables, or chemical structures were manually identified and excluded by a clinician.
  • ChatGPT was invoked via the official API using gpt-3.5-turbo with default parameters. Direct instruction prompts were used to force clear answers and distinguish single-choice from multiple-choice questions.
  • Each response was manually reviewed by an experienced clinician and scored 1 for agreement with the true answer or 0 for disagreement. Data processing used Python 3.9.13 in Jupyter Notebook, statistical analysis used GraphPad Prism 9, and significance was set at p < 0.05.

Limitations

  • Stated: the exams were all multiple-choice, so open-ended content generation was not fully assessed; evaluation used zero-shot learning; prompt variations may affect responses; and further investigation is needed into causes of substandard performance and broader applications.
  • Evident: the study evaluated only ChatGPT/GPT-3.5, so findings may not generalize to other large language models or versions.
  • Evident: excluding questions with figures, tables, or chemical structures may limit how fully the exams represent the original test content.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
