Evaluating ChatGPT responses on thyroid nodules for patient education.BACKGROUND
 ChatGPT, an artificial intelligence (AI) chatbot, is the fastest growing consumer application in history.  Given recent trends identifying increasing patient use of Internet sources for self-education, we seek to evaluate the quality of ChatGPT-generated responses for patient education on thyroid nodules.


 ChatGPT was queried 4 times with 30 identical questions.  References provided within ChatGPT answers were totaled and analyzed for veracity.


 ChatGPT overall provides appropriate answers to most questions on thyroid nodules regardless of prompting.  Despite targeted prompting strategies, ChatGPT reliably generates responses corresponding to grade levels well-above accepted recommendations for presenting medical information to patients.  Significant rates of AI hallucination may preclude clinicians from recommending the current version of ChatGPT as an educational tool for patients at this time.
