Summary

CAREAgent is a novel clinical agent designed for generating fine-grained, executable clinical orders, addressing a gap where existing agents focus on coarse-grained decisions. Developed by authors publishing on 2026-05-31, CAREAgent employs a two-stage agentic reasoning data construction method. This involves first designing an agent framework to build verifiable reasoning trajectories aligned with realistic clinical tool usage, then filtering these trajectories based on format compliance, order validity, and clinical plausibility. The model undergoes supervised fine-tuning to acquire foundational reasoning formats and medical knowledge, followed by optimization through reinforcement learning using multi-dimensional reward functions to enhance complex clinical reasoning. Experimental results on the unseen ClinicalBench benchmark demonstrate CAREAgent's effectiveness, improving the F1 score by 5.05% compared to single-agent methods, 2.09% over multi-agent methods, and 0.86% over agentic reasoning methods.

Key takeaway

For clinical AI developers building agents for detailed order generation, CAREAgent presents a validated methodology to overcome limitations of coarse-grained systems. You should consider its two-stage data construction and hybrid supervised/reinforcement learning approach to improve accuracy and clinical plausibility. This method significantly enhances F1 scores on unseen benchmarks, suggesting a path to more reliable and executable medical decision translation in your applications.
