How good is ChatGPT at answering patients' questions related to early detection of oral (mouth) cancer?

OBJECTIVES: To examine the quality, reliability, readability, and usefulness of ChatGPT in promoting oral cancer early detection. STUDY DESIGN: About 108 patient-oriented questions about oral cancer early detection were compiled from expert panels, professional societies, and web-based tools. Questions were categorized into 4 topic domains and ChatGPT 3.5 was asked each question independently. ChatGPT answers were evaluated regarding quality, readability, actionability, and usefulness using. Two experienced reviewers independently assessed each response. RESULTS: Questions related to clinical appearance constituted 36.1% (n = 39) of the total questions. ChatGPT provided "very useful" responses to the majority of questions (75%; n = 81). The mean Global Quality Score was 4.24 +/- 1.3 of 5. The mean reliability score was 23.17 +/- 9.87 of 25. The mean understandability score was 76.6% +/- 25.9% of 100, while the mean actionability score was 47.3% +/- 18.9% of 100. The mean FKS reading ease score was 38.4% +/- 29.9%, while the mean SMOG index readability score was 11.65 +/- 8.4. No misleading information was identified among ChatGPT responses. CONCLUSION: ChatGPT is an attractive and potentially useful resource for informing patients about early detection of oral cancer. Nevertheless, concerns do exist about readability and actionability of the offered information.
