Large language models in practice: insights from building LLM-based pipelines for paediatric healthcare data

Great Ormond Street Hospital (GOSH), a specialist pediatric hospital, is utilizing large language models (LLMs) to enhance the analysis of healthcare data collected from children. The DRIVE initiative aims to improve outcomes by integrating AI into clinical, patient, and operational support, while ensuring data security and compliance with ethical standards. Initial experiments with LLMs have shown improved performance in summarizing complex medical reports compared to traditional rule-based methods. However, challenges remain, such as the need for efficient processing and the importance of clinician validation. GOSH emphasizes collaboration and gradual implementation of AI solutions to build trust and address stakeholder concerns.
