Study on the suppport for medical decision making and its evaluations.

经过两年的合作研究，取得了以下成果：1）开发了UMIN（大学医院医学信息网），建立了网络环境下的数据库管理系统; 2）研究了临床数据集成方法，以支持医生的决策。集成的难点之一是管理图像数据（X射线图像等）。一般采用PACS（Picture Storage and Communication System）进行处理。3）探讨了医学数据的标准化和统一化问题，提出了医学数据的统一建模语言（UMLS）日本医学信息学引进美国的统一医学语言系统（UnifiedMedicalLanguageSystem）; 4）在部分地区建立器官移植网络，作为面向多用户的数据库和医院间计算机网络的模型;研究了医学信息学的应用实例，开发了医院信息系统中的医嘱录入和报表系统，并将医学智能应用于医疗保健专家系统。

Results of the cooperative study for two years am as follow ;1) UMIN (University hospital's Medical Information Network) has been developed and database management system is constructed to be utilized under network environment.2) Methodology for integration of clinical data to support doctors' decision making has been studied. One of the difficulties for the integration is to manage image data (X-ray images etc.) which are generally treated with PACS (Picture Archiving and Communication System). Some prototypes of PACS were developed and evaluated clinically.3) Standardization and unification of medical data were discussed and UMLS (Unified Medical Language System) in the USA was introduced to medical informatics in Japan.4) Organ transplantation networks were lied to be constructed in some regions as a model of multi-user oriented database and interhospital computer network.5) Some examples of application of medical informatics were studied.Order entry and reporting system in hopital information system were developed.Artifical intelligence was applied to some expert system in medical care.
