Evaluating the Performance of State-of-the-Art Artificial Intelligence Chatbots Based on the WHO Global Guidelines for the Prevention of Surgical Site Infection: Cross-Sectional Study.

Background: Surgical site infection (SSI) is the most prevalent type of health care-associated infection that leads to increased morbidity and mortality and a significant economic burden. Effective prevention of SSI relies on surgeons strictly following the latest clinical guidelines and implementing standardized and multilevel intervention strategies. However, the frequent updates to clinical guidelines render the processes of acquisition and interpretation quite time-consuming and intricate. The emergence of artificial intelligence (AI) chatbots offers both possibilities and challenges to address these issues in the surgical field. Objective: This study aimed to test the multidimensional capability of state-of-the-art AI chatbots for generating proper recommendations and corresponding rationales concordant with the global guideline for the prevention of SSI. Methods: Referred by other authoritative guidelines, recommendations and corresponding rationales from the 2018 World Health Organization global guidelines were refined and selected as benchmarks. Then, they were rephrased into a combined format of closed-ended queries for recommendations and open-ended queries for corresponding rationales, whereafter input into ChatGPT-4o (OpenAI), OpenAI-o1 (OpenAI), Claude 3.5 Sonnet (Anthropic), and Gemini 1.5 Pro (Google) 3 times. All responses were individually evaluated in 10 evaluation metrics based on the QUEST dimensions by 4 multidisciplinary senior surgeons using a 5-point Likert scale. The multidimensional performances among chatbots were compared, and the interrater agreements were calculated. Results: A total of 300 responses to 25 queries were generated by the 4 chatbots. The interrater agreements of the evaluators ranged from moderate to good (0.54-0.87). In response to recommendations, the average accuracy, consistency, and harm scores for all chatbots were 4.03 (SD 1.09), 4.07 (SD 0.88), and 4.29 (SD 1.01), respectively. In responses for rationales, 4 subdimensions, including harm (mean 4.22, SD 0.97), relevance (mean 4.15, SD 0.83), fabrication and falsification (mean 4.12, SD 1.02), and understanding and reasoning (mean 4.04, SD 0.92) averagely scored ≥4. In contrast, consistency (mean 3.94, SD 0.72), clarity (mean 3.94, SD 0.89), comprehensiveness (mean 3.85, SD 0.83), and accuracy (mean 3.74, SD 0.91) performed at a moderate level. For the whole responses, the average self-awareness and trust and confidence scores for all chatbots were 3.84 (SD 0.89) and 3.88 (SD 0.91), respectively. Based on the average scores of the subdimensions, Claude 3.5 Sonnet and ChatGPT-4o were the top 2 outperformed models. Conclusions: The performance of AI chatbots in providing responses regarding well-established global guidelines in the prevention of SSI was acceptable, demonstrating immense potential in clinical applications. Nonetheless, a critical issue is the necessity of enhancing the stability of chatbots, as inaccurate responses can lead to severe consequences for SSI. Despite its limitations, it is anticipated that AI will trigger far-reaching changes in how clinicians access and use medical information.
