本次演讲将围绕急诊患者分流模式进行阐述，介绍北京协和医院作为大型三级甲等综合性医院如何围绕急诊临床实践中面临的诊疗资源稀缺，依据医疗政策支撑，合理落地构建创新型的诊疗模式，改善大型医疗机构急诊科诊疗压力，以急诊医学为例，切实实现分级诊疗策略，服务于患者，并为不同医疗机构带来医疗、教学、研究、管理的全面提升，解决患者看病难的诊疗服务困境。
This presentation will elaborate on the triage model for emergency patients, introducing how Peking Union Medical College Hospital, as a large tertiary grade-A general hospital, addresses the scarcity of diagnostic and treatment resources faced in emergency clinical practice. Guided by medical policy support, the hospital has rationally implemented and built an innovative diagnostic and treatment model to alleviate the diagnostic and treatment pressures in the emergency department of large medical institutions. Taking emergency medicine as an example, this model effectively implements a hierarchical medical care strategy, serves patients, and brings comprehensive improvements in medical care, teaching, research, and management to different medical institutions, thereby solving the dilemma of difficult access to medical services for patients.

The core objective of the Green Channel for Chest Pain is to identify, diagnose and manage patients with chest pain in the shortest possible time, thereby effectively reducing mortality and the risk of complications. To achieve this goal, a multidisciplinary and multidepartmental collaboration mechanism must be established, covering the prehospital emergency care system, the emergency department, the cardiology department, as well as all relevant departments such as imaging and testing. First, the prehospital emergency care process should be optimized, and remote cardiac monitoring and information connectivity should be strengthened to ensure that patients are identified and treated in a timely manner. Second, a green channel should be opened in the hospital to reduce delays by simplifying registration, opening up emergency examination equipment, and seamlessly connecting with the catheterization room to strengthen the rapid identification and emergency treatment of high-risk chest pain. Further combining with "Internet+" means to carry out inter-hospital information sharing and remote consultation can effectively enhance regional collaborative treatment capacity. In addition, extensive first aid training should be provided to the public and medical personnel to popularize the knowledge of cardiopulmonary resuscitation (CPR) and the use of AED, to improve the rate of bystander intervention and shorten the golden time for treatment. On this basis, through regular drills and quality control, the workflow should be improved and the overall efficiency of treatment should be enhanced. Through the effective connection of the above links, the Chest Pain Green Channel can better protect patient safety and reduce the mortality and disability rate of chest pain-related diseases.
胸痛绿色通道的核心目标是在最短时间内识别、诊断并处理胸痛患者，从而有效降低死亡率和并发症风险。要实现这一目标，必须建立多学科、多部门协作机制，涵盖院前急救系统、急诊科、心内科以及影像、检验等各相关科室。首先，应优化院前急救流程，加强远程心电监护和信息联通，确保患者得到及时识别与处理。其次，院内应开通绿色通道，通过简化登记、开放急诊检查设备，以及与导管室的无缝衔接来减少延误，加强对高危胸痛的快速识别与紧急处理。进一步结合"互联网+"手段，开展跨院际信息共享与远程会诊，可有效提升区域协同救治能力。此外，应对公众和医务人员进行广泛的急救培训，普及心肺复苏（CPR）和AED使用知识，提高旁观者干预率，缩短救治黄金时间。在此基础上，通过定期演练和质量控制，不断完善工作流程并提升整体救治效率。通过以上多环节的有效衔接，胸痛绿色通道才能更好地保障患者安全、降低胸痛相关疾病的致死率和致残率。

静脉溶栓是急性缺血性卒中标准疗法，但严格受 4.5 小时时间窗限制，缩短患者到院至静脉溶栓时间（DNT）是国际研究的重点和难点。为此，研究团队创新性的将国产 0.23T 低场强 MRI 设备置于急诊室，首创 "急诊卒中单元" 概念。该模式整合临床评估、影像评估及治疗环节，在同一空间完成高度组织化管理，简化缺血性卒中再灌注治疗流程，有效减少院内延误，实现快速诊断与治疗，提升诊疗精准度和效率，降低患者致死致残率。同时，团队开展多中心、大样本随机对照试验，对比该新型模式与传统急诊绿色通道模式对 DNT 的影响。研究成果有望突破现有缺血性卒中溶栓治疗面临的局限性，提供中国独创诊疗方案，改善患者临床预后，同时扩大获益人群。
