| 電子病歷中重疊時態數據的分析與消除 黃雄波[1] 陳章[2] 岳喜順[1] [1]華南理工大學自動化科學與工程學院,廣東廣州510641 [2]廣東商學院信息學院,廣東廣州510320 摘 要:隨著醫療數字化的發展，傳統的紙張書寫病歷正逐漸向電子病歷轉變。在醫院的現代化管理過程中，電子病歷作為醫療活動信息的主要載體而成為了醫院信息系統的核心，同時，它的設計也是醫院信息系統中最為關鍵的技術。文中用M.A.Roth等學者提出的嵌套關系數據庫模型在非時態DBMS上設計了電子病歷的時態數據庫，分析了該模型下產生重疊時態數據的原因，并在Delphi中詳細討論了重疊時態數據的消除原理及編程方法。 關鍵詞:嵌套關系數據庫模型 重疊時態數據 電子病歷 Delphi 分類號: TP311.11 文獻標識碼：A 文章編號：1673-629X（2009）03-0235-04 Analysis and Elimination of Overlapping Temporal Data in Electronic Medical Record HUANG Xiong-bo, CHEN Zhang, YUE Xi-shun 1. School of Automation Sci. and Eng., South China Univ. of Tech. ,Guangzhou 510641 ,China; 2. School of Information, Guangdong Univ. of Business Studies,Guangzhou 510320,China Abstract:With the development in medical treatment digitization, paper medical record changes to electronic medical record（EMR）. As the main carrier of the medical activity information,EMR is the core of the hospital information system in the process of modem manage- ment of the hospital,mad the design of EMR is the key technique of HIS. Using nested relational DB model introduced by M. A. Roth, constructs a kind of temporal database of electronic medical record which is based on none-temporary DBMS. But since information in electronic medical record changes as time passes by, the problem of overlapping temporal data may easily turn up. Analyzes the reason of the problem, discusses the main principle to solve it, and introduces the programming method in Delphi. Key words:nested relational DB model;overlapping temporal data; electronic medical retard;Delphi |
