In contrast, EHR foundation models can learn predictive patient representations, yet lack interpretable language-based reasoning. To bridge this gap, we propose ChatHealthAI, a multimodal reasoning framework that aligns structured EHR representations from a pretrained EHR foundation model with the semantic space of a frozen LLM through a task-aware resampler. By integrating longitudinal patient representations with refined clinical event descriptions, ChatHealthAI enables clinically grounded natural-language reasoning while maintaining accurate patient prediction. We evaluated ChatHealthAI on three clinical predictive tasks from the EHRSHOT benchmark. Results show that ChatHealthAI improves reasoning quality and interpretability while preserving competitive predictive performance. These findings highlight the potential of integrating EHR foundation models with pretrained LLMs for interpretable clinical prediction.", "url": "https://wpnews.pro/news/chathealthai-aligning-electronic-health-record-representations-with-large-models", "canonical_source": "https://arxiv.org/abs/2606.02802", "published_at": "2026-06-03 04:00:00+00:00", "updated_at": "2026-06-03 04:16:55.717964+00:00", "lang": "en", "topics": ["large-language-models", "natural-language-processing", "machine-learning", "artificial-intelligence"], "entities": ["ChatHealthAI", "EHRSHOT"], "alternates": {"html": "https://wpnews.pro/news/chathealthai-aligning-electronic-health-record-representations-with-large-models", "markdown": "https://wpnews.pro/news/chathealthai-aligning-electronic-health-record-representations-with-large-models.md", "text": "https://wpnews.pro/news/chathealthai-aligning-electronic-health-record-representations-with-large-models.txt", "jsonld": "https://wpnews.pro/news/chathealthai-aligning-electronic-health-record-representations-with-large-models.jsonld"}}
