Distinct but correct: generating diversified and entity-revised medical response

引用

Science China(Information Sciences) 2024年第3期67卷 94-113页

作者： Bin LI Bin SUN Shutao LI Encheng CHEN Hongru LIU Yixuan WENG Yongping BAI Meiling HU College of Electrical and Information Engineering Hunan University School of Mathematics Sun Yat-sen University JD Technology National Laboratory of Pattern Recognition Institute of AutomationChinese Academy of Sciences Xiangya Hospital of Central South University teaching and research section of Clinical Nursing Xiangya Hospital of Central South University

Medical dialogue generation(MDG) is applied for building medical dialogue systems for intelligent consultation. Such systems can communicate with patients in real time, thereby improving the efficiency of clinical diagnosis. However, predicting correct entities and correctly generating distinct responses remain a great challenge. Inspired by actual doctors’ responses to patients, we consider MDG a two-stage task: entity prediction and dialogue generation. For entity prediction, we design an ent-mac post pre-training strategy by leveraging external medical entity knowledge to enhance the pre-trained model. For dialogue generation, we propose an entity-aware fusion MDG method in which predicted entities are integrated into the dialogue generation model through different encoding fusion mechanisms, using information from different sources. Because the diverse beam search algorithm can produce responses with entities that deviate from the predicted entities, an entity-revised diverse beam search is proposed to correct the entities entailed in the generated responses and make the generated responses more distinct. The experimental results on the China Conference on Knowledge Graph and Semantic Computing 2021(A/B tests) and the International Conference on Learning Representations 2021(online test) datasets show that the proposed method outperforms several state-of-the-art methods, which demonstrates its practicability and effectiveness.

目的医疗设备的频繁虚假警报可能导致护土警报疲劳,这可能导致反应行动延迟或错过警报,增加患者不良事件的风险。本综述旨在探讨重症监护室临床警报智慧化管理措施对减少临床虚假警报的应用效果。方法根据Whitmore 和Knaf的方法学框架,对6个数据库进行系统检索: PubMed, EMBASE,CINAHL,OVID,CochraneLibrary,Scopus,检索从每个数据库建库到2022年12月以英文或中文发表的临床警报的智慧化管理相关文章。采用乔安娜布里格斯研究所的评价工具(JBI-MAStARI)评估研究的质量,并对文献进行数据提取和分析。该研究已在PROSPERO完成注册(CRD42023411552)。结果共纳入7项研究。不同的警报智慧化管理措施有利于减少虚假警报数量和警报的持续时间,缩短护士对重要警报的应答时间,减轻护士的警报疲劳程度。在实践中,应用新的警报管理方式后取得了积极的效果。结论智慧化管理措施可能是警报减少的有效途径,医院迫切需要进行临床警报的智慧化管理。为确保更有效的患者监测、减少警报给护士带来的困扰,未来需要更多与人工智能相结合的警报管理手段,以实现关键警报的准确识别,确保护士对警报准确响应,并真正改善警报频繁的临床医疗环境。
