AI总结:

针对现有基准无法评估MLLMs复杂临床多模态任务能力的问题,提出Med-PMC个性化多模态问诊范式,通过含个性化患者模拟器的临床环境测试12类MLLMs,发现其存在信息收集不足与决策偏差问题,为临床MLLMs研发提供指导。

摘要:

多模态大语言模型(MLLMs)在医疗临床场景中的应用仍有待深入探索。现有基准仅关注MLLMs在医疗视觉问答(VQA)或报告生成方面的能力,未能评估其在复杂临床多模态任务上的表现。本文提出一种全新的医疗个性化多模态问诊(Medical Personalized Multi-modal Consultation,Med-PMC)范式,用于评估MLLMs的临床能力。Med-PMC构建了模拟临床环境,要求MLLMs与患者模拟器交互,完成多模态信息收集与决策任务。具体而言,患者模拟器配备了个性化角色设定,以模拟真实场景中的多样化患者。我们开展了大量实验,对12种MLLMs进行评估,全面呈现了MLLMs的临床表现。研究发现,当前的MLLMs在与个性化患者模拟器交互时,无法有效收集多模态信息,且在决策任务中表现出潜在偏差。进一步分析验证了Med-PMC的有效性,显示其有望指导鲁棒、可靠的临床MLLMs的开发。代码与数据可在https://github.com/LiuHC0428/Med-PMC获取。

英文摘要:

The application of the Multi-modal Large Language Models (MLLMs) in medical clinical scenarios remains underexplored. Previous benchmarks only focus on the capacity of the MLLMs in medical visual question-answering (VQA) or report generation and fail to assess the performance of the MLLMs on complex clinical multi-modal tasks. In this paper, we propose a novel Medical Personalized Multi-modal Consultation (Med-PMC) paradigm to evaluate the clinical capacity of the MLLMs. Med-PMC builds a simulated clinical environment where the MLLMs are required to interact with a patient simulator to complete the multi-modal information-gathering and decision-making task. Specifically, the patient simulator is decorated with personalized actors to simulate diverse patients in real scenarios. We conduct extensive experiments to access 12 types of MLLMs, providing a comprehensive view of the MLLMs' clinical performance. We found that current MLLMs fail to gather multimodal information and show potential bias in the decision-making task when consulted with the personalized patient simulators. Further analysis demonstrates the effectiveness of Med-PMC, showing the potential to guide the development of robust and reliable clinical MLLMs. Code and data are available at https://github.com/LiuHC0428/Med-PMC.
