Decoding the NCCN Guidelines With AI: A Comparative Evaluation of ChatGPT-4.0 and Llama 2 in the Management of Thyroid Carcinoma

Abstract

Introduction Artificial Intelligence (AI) has emerged as a promising tool in the delivery of health care. ChatGPT-4.0 (OpenAI, San Francisco, California) and Llama 2 (Meta, Menlo Park, CA) have each gained attention for their use in various medical applications. Objective This study aims to evaluate and compare the effectiveness of ChatGPT-4.0 and Llama 2 in assisting with complex clinical decision making in the diagnosis and treatment of thyroid carcinoma. Participants We reviewed the National Comprehensive Cancer Network® (NCCN) Clinical Practice Guidelines for the management of thyroid carcinoma and formulated up to 3 complex clinical questions for each decision-making page. ChatGPT-4.0 and Llama 2 were queried in a reproducible manner. The answers were scored on a Likert scale: 5) Correct; 4) correct, with missing information requiring clarification; 3) correct, but unable to complete answer; 2) partially incorrect; 1) absolutely incorrect. Score frequencies were compared, and subgroup analysis was conducted on Correctness (defined as scores 1-2 vs 3-5) and Accuracy (scores 1-3 vs 4-5). Results In total, 58 pages of the NCCN Guidelines® were analyzed, generating 167 unique questions. There was no statistically significant difference between ChatGPT-4.0 and Llama 2 in terms of overall score (Mann-Whitney U-test; Mean Rank = 160.53 vs 174.47, P = 0.123), Correctness ( P = 0.177), or Accuracy ( P = 0.891). [Formula: see text] Conclusion ChatGPT-4.0 and Llama 2 demonstrate a limited but substantial capacity to assist with complex clinical decision making relating to the management of thyroid carcinoma, with no significant difference in their effectiveness.
