摘 要:該報告圍繞信息服務運行支撐平臺的關鍵技術及醫療信息服務兩部分展開。在構建信息服務平臺方面,主要研究了平臺的體系結構,研究了信息服務的檢索、聚合、演化、評測、執行監控等模塊的關鍵技術,實現了一個集成的信息服務支撐平臺。在服務檢索方面,我們從服務的情景入手,研究了情景敏感的服務檢索;在服務聚合方面,我們從語義、服務質量、事務等多維屬性入手,設計了支持并發需求與服務關聯的服務聚合方法、基于混合博弈的服務聚合方法;在服務演化方面,我們采用自頂向下與自下向上的研究方法,設計實現了支持演化的流程引擎和面向用戶的需求變化管理平臺;在服務評測方面,研究了服務質量的動態預測方法與可信模型;在執行監控方面,我們采用AOP技術設計實現了監控引擎。最終我們實現了一個滿足用戶多維需求的可伸縮、可擴展的信息服務平臺。在醫療信息服務的研究方面,面向用戶的多樣化和個性化需求,以實現跨組織的醫療信息服務協同為目標,設計了電子健康檔案服務、公眾醫療就診輔助服務、醫療轉診服務、醫療隨訪服務和醫療服務流程。電子健康檔案服務為每個人建立一個健康檔案,實現個體化程度上的健康管理,這樣無論是在基層就醫或者到大醫院就醫,醫生馬上就可以知道患者病史,避免了很多重復的醫學檢查,并有針對性地進行醫療診治準備;公眾醫療就診輔助服務為個人用戶提供預約掛號、疾病自檢功能;醫療轉診服務利用信息網絡資源及共享數據交換平臺,將醫院信息系統與社區衛生服務機構的信息系統進行連接,為轉診對象的診前預約、就診過程及診后服務全過程提供相關信息支持;醫療隨訪服務主要用于建立糖尿病、高血壓病人康復情況、生存情況、長期療效、各種治療方案的全面的醫療檔案,通過這個醫療隨訪平臺,醫生、醫院、病人可以長期地相互協作,促進糖尿病、高血壓等慢性病的防治和治療;醫療服務流程通過對相關醫療信息服務的組合來構造支撐不同醫療分工協作機制的各類應用,同時以第三方的角度實現對所有醫療信息服務的統一管理和監控,并面向各類醫療協作應用提供統一的部署和運行支撐。

Abstract:The report is organized around the key technologies of the operating platform and medical information services. In the construction of platform, we study a series of problems, including the architecture, service retrieval, service composition, service evaluation, service evolution, service execution monitoring, et al.(1) service retrieval: we start from the context of service and design a service retrieval system.(2) service composition: we start from the multi-dimension properties which include semantic, QoS and transaction. A service composition approach supporting concurrent requests and service association is proposed. To solve the problem of multi-object service composition, a hybrid-game method is presented.(3) service evolution: we analyze the change from top to down, and realize a workflow engine supporting service evolution.(4) service evaluation: the prediction method and trust model of QoS are proposed.(5) execution monitoring: the AOP technique is adopted. Finally, we set up an integrated information service platform. In the research and development of medical information services, we aim at the services collaborative cross different medical organizations. The electronic health records service, public health clinic support service, medical referral service, medical follow-up service, and medical service process are designed.(1)The aim of electronic health records service is to build a health record for everyone, so the doctor can immediately know the patient's history and avoid a lot of duplicate medical examination, and to prepare and carry out medical treatment.(2)Public health clinic support service provides support for making an appointment and illness self-test function.(3)Medical referral service uses of the information of network resources and the data exchange platform to support the whole medical referral process.(4)Through the medical follow-up service, the doctors, hospitals, patients can collaborate to prevent and cure diabetes, hypertension and other chronic disease.(5)Medical service process supports different types of medical applications through a combination of relevant medical information services, while the third-party manages and monitors all the medical information services.
