GPT-4 Demonstrates Superior Readability in Bariatric Surgery Patient Education

Large language models (LLMs) like GPT-4 significantly improve the readability of bariatric surgery patient education materials (PEMs), with responses ranging from 6th to 9th grade reading levels. While GPT-3.5 and GPT-4 showed similar accuracy and comprehensiveness in simplifying responses, Bard’s responses were less comprehensive when simplified. This study emphasizes the potential of LLMs in enhancing the accessibility of PEMs for patients with varying literacy levels, advocating for further research in personalized PEM delivery.
