AI meets gastroenterology practice: mapping large language model use across Europe – EuroGI-AI project

Background and aims The use of large language models (LLMs), such as ChatGPT, is rapidly expanding in clinical medicine but data in gastroenterology are limited. We aimed to assess the prevalence and patterns of LLM use among European gastroenterologists, evaluate perceived benefits and risks and identify barriers and priorities for future integration. Methods A Europe-wide online survey was conducted between June and August 2025. A 24-item questionnaire was distributed via national gastroenterology societies and social media. Questions on specific applications, reliability and clinical impact were shown only to respondents with prior LLM experience. Results A total of 966 gastroenterologists from 34 European countries responded, 55.3% reported using LLMs, mainly weekly (54.4%) or daily (20.2%). Common uses included education (59.2%), clinical decision support (58.2%) and scientific writing (39.1%). Among academic users, summarisation (80.1%) and grammar refinement (74.4%) were most frequent. Most users rated LLMs as moderately or highly reliable (81.0%), and 84.3% believed they improve outcomes. Nearly two-thirds (64.5%) felt LLMs can support endoscopy practice. Inaccuracies were reported by 42.7% and were associated with lower trust (ρ=–0.40, p
