A Meta-Analysis of ChatGPT's Performance on Dermatology Specialty-Level (Board-Style) Certification Questions
1The School of Medicine, The University of Auckland, New Zealand.
Background And Objective:
ChatGPT, an advanced artificial intelligence chatbot, has shown promise in various medical applications, including dermatology. This meta-analysis evaluates its performance on dermatology specialty (board-style) certification questions based on evidence from multiple studies.
Materials And Methods:
We searched PubMed/MEDLINE and EMBASE for studies published up to December 10, 2024, using predefined search terms or keywords. A random-effects model estimated ChatGPT's overall performance on dermatology specialty certification (board-style) questions, with 95% confidence intervals and subgroup analyses by ChatGPT version (GPT-3.5 or GPT-4.0). Statistical analysis used STATA 17, with heterogeneity assessed by the I ² statistic, and significance set at P < 0.05.
Results:
A total of 13 studies were included in this meta-analysis. The overall pooled accuracy of ChatGPT, across both GPT-3.5 and GPT-4.0 versions, was 69.97% (95% CI: 64.64-75.05%, I ² = 93.28%, P value = 0.00). ChatGPT-4.0 showed the highest overall accuracy of 79.46% (95% CI: 75.36-83.30%, I ² = 72.79%, P value = 0.00) compared to ChatGPT-3.5, which showed an overall accuracy of 61.07% (95% CI: 57.36-64.72%, I ² = 72.97%, P value = 0.00).
Limitations:
This study includes only English-language publications and focuses solely on ChatGPT's performance in dermatology exams, limiting its generalizability for clinical or patient education use. Significant heterogeneity warrants further research into potential causes such as question difficulty, dermatology subdomains, and question format and layout.
Conclusion:
Notwithstanding its limitations, this meta-analysis highlights ChatGPT's potential to serve as an additional educational resource for candidates preparing to sit dermatology specialty (board-level) certification examinations and for supporting their overall educational development.
