📝 摘要(中文)
出院总结是患者就医过程中至关重要的文件,涵盖住院期间的所有事件,包括多次就诊、用药、检查、手术及入院/出院信息。提供患者进展的总结对未来的护理和规划至关重要。然而,临床医生面临着手动收集、整理和组合所有必要数据的繁重任务。为此,本文提出了“NOTE”,即“通过直接偏好优化的高效患者文本总结生成”。NOTE基于医疗信息市场III数据集,旨在总结患者的单次住院经历。我们采用DPO和参数高效微调技术,确保在医院内部服务器上实现轻量化模型的最佳性能。未来,我们将部署该软件供临床医生实际使用。
🔬 方法详解
问题定义:本文旨在解决临床医生在生成患者出院总结时面临的手动数据整理的繁重工作。现有方法在数据隐私保护和效率上存在明显不足。
核心思路:论文提出NOTE,通过直接偏好优化(DPO)和参数高效微调(PEFT)技术,自动化生成患者的出院总结,旨在提高效率并减轻医生的工作负担。
技术框架:整体架构包括数据收集、事件序列化、文本生成和结果展示四个主要模块。首先,从医疗信息市场III数据集中提取患者数据,然后将事件按顺序组合,最后生成出院总结并通过网页展示。
关键创新:NOTE的核心创新在于结合DPO和PEFT技术,使得模型在保证性能的同时,能够在医院内部轻量化运行,克服了数据隐私保护的挑战。
关键设计:在模型设计中,采用了特定的损失函数以优化生成文本的连贯性和准确性,同时通过参数高效微调技术,减少了训练所需的计算资源。具体的网络结构和参数设置尚未详细披露。

🎯 应用场景
NOTE的潜在应用领域包括医院的出院总结生成、患者护理记录的自动化以及临床数据的整合与分析。其实际价值在于提高临床工作效率,减少医生的手动工作量,未来可能对医疗行业的数字化转型产生深远影响。
📄 摘要(原文)
The discharge summary is a one of critical documents in the patient journey, encompassing all events experienced during hospitalization, including multiple visits, medications, tests, surgery/procedures, and admissions/discharge. Providing a summary of the patient's progress is crucial, as it significantly influences future care and planning. Consequently, clinicians face the laborious and resource-intensive task of manually collecting, organizing, and combining all the necessary data for a discharge summary. Therefore, we propose "NOTE", which stands for "Notable generation Of patient Text summaries through an Efficient approach based on direct preference optimization". NOTE is based on Medical Information Mart for Intensive Care- III dataset and summarizes a single hospitalization of a patient. Patient events are sequentially combined and used to generate a discharge summary for each hospitalization. In the present circumstances, large language models' application programming interfaces (LLMs' APIs) are widely available, but importing and exporting medical data presents significant challenges due to privacy protection policies in healthcare institutions. Moreover, to ensure optimal performance, it is essential to implement a lightweight model for internal server or program within the hospital. Therefore, we utilized DPO and parameter efficient fine tuning (PEFT) techniques to apply a fine-tuning method that guarantees superior performance. To demonstrate the practical application of the developed NOTE, we provide a webpage-based demonstration software. In the future, we will aim to deploy the software available for actual use by clinicians in hospital. NOTE can be utilized to generate various summaries not only discharge summaries but also throughout a patient's journey, thereby alleviating the labor-intensive workload of clinicians and aiming for increased efficiency.
