Researchers have developed SepsisAgent, a novel system that integrates a clinical world model with large language models (LLMs) to improve sepsis management in intensive care units. This agent uses the world model to simulate patient responses to different fluid and vasopressor interventions, employing a propose-simulate-refine workflow for treatment recommendations. Training involved a three-stage curriculum, including supervised fine-tuning and agentic reinforcement learning, which resulted in SepsisAgent outperforming traditional RL and LLM baselines on sepsis trajectories from MIMIC-IV data.
