    复旦大学附属中山医院是中国最好的医院之一,综合实力常年在国内各类医院榜单名列前茅。中山医院从1992年起就开始借助信息系统管理日常工作,近年来在席卷中国医院的数字化转型浪潮中力争前沿,加大投入、建立组织机制,围绕“患者管理人性化”“资源管理功能化”“业务管理智能化”三大主题,探索打造智慧医院样板,得到医疗卫生监管部门、患者和社会的广泛认可。 2022年2月,上海市赋予中山医院探索打造未来医院的重任,从方案发布到完成场景建设,只有4个半月时间。这构成了本案例的主要决策场景。中山医院需要在整理既有成果的基础上,尽快解决三个问题: 第一,如何定义自己的未来医院?该定义还应具备一定的普适性,以利于将来的推广。 第二,中山医院目前的工作主线是“高质量发展”,如何将未来医院建设目标与“高质量发展”目标整合起来,相互赋能、一体推动? 第三,如何借由智慧医院建设,使数字化转型上升到文化层面,即数字化改变人的认知和行为方式的高度?Zhongshan Hospital Affiliated to Fudan University is one of the top hospitals in China, consistently ranking among the best in various domestic hospital rankings due to its comprehensive strength. Since 1992, Zhongshan Hospital has been leveraging information systems to manage daily operations. In recent years, it has actively embraced the digital transformation wave sweeping across Chinese hospitals, increasing investments, establishing organizational mechanisms, and focusing on three main themes: "humanistic patient management", "functionalized resource management" and "intelligent business management ". It aims to explore the creation of a smart hospital model and has gained widespread recognition from healthcare regulatory authorities, patients, and society. In February 2022, the city of Shanghai entrusted Zhongshan Hospital with the task of exploring the construction of the future hospital. From the release of the plan to the completion of scenario development, there was a tight timeline of only four and a half months. This sets the main decision-making scenario for this case. Zhongshan Hospital needs to address three key issues quickly, building upon its existing achievements: First, how to define its own hospital of the future? This definition should also have a certain universality to facilitate future promotion. Second, how to integrate the goals of future hospital construction with the goals of "high-quality development", which is the current work focus of Zhongshan Hospital, so as to empower each other? Third, how to elevate digital transformation to the cultural level through the construction of a smart hospital, i.e., how to bring about a profound change in people's cognition and behavior through digitization
