A Study of Object Description and Implementation of Prescriptions, Clinical Laboratory Test Results, and Diagnostic Disease Classifications, for the Purpose of Clinical Case Data-base

对临床病例资料的处方、临床实验室检查结果、诊断疾病分类进行客观分析。方法和语义轴的分析，使他们可以用于智能数据检索的临床支持。因此，处方应按功效、给药途径和用药方式进行分类。临床实验室检测结果的检测方法、标本品种。然后，将滨松大学医院信息系统中出现的这3种日常事务数据全部转换为HL 7消息数据类型。并将它们发送到面向对象的数据库，在那里这些数据被分类并存储为对象表示。这是日本首次将如此庞大的医院日常信息数据以标准化的格式传输到临床支持数据库中。一天中的所有数据都在午夜发送到面向对象的数据库。通过这样做，根据ICD-9-CM分类登记的诊断疾病被转换为疾病状态的SNOMED描述。研究人员还创建了该自动转换程序。临床支持面向对象的数据库，其丰富的层次结构中的数据语义表示，可以允许抽象级别的检索，例如“任何被处方xxx系列抗生素的患者，至少有一次GOT的最高记录超过100。“研究人员认为，临床信息检索的这种抽象程度是以前从未实现过的。研究人员希望，随着这一开创性实验的开展，HL 7在日本医院的实施将会增加，并且真实的语义临床支持将在不久的将来实现。

Object analysis were applied to prescription, clinical lab test results, and diagnostic disease classifications of clinical case data. Methods and semantic axis of analysis were investigated so that they can be used for intelligent data retrieval for clinical supports. As the results, prescriptions should be categorized in effects, medication routes, and medicine styles. Clinical laboratory test results in test methods, and specimen varieties. Diagnostic disease classifications in anatomical sites, and pathophysiological states.Then, the researcher made a conversion method to change all daily transaction data of these three kinds, arose in Hamamatsu University Hospital information systems, into HL7 message data types. And they are sent to object oriented data-base, where these data are categorized and storec as object representations. This is the first case in Japan, that this huge amount of daily hospital information data transmitted into clinical support data-base in standardized format. All the day's data are sent to Object-oriented data-base in the midnight of the day. By doing this, diagnostic disease registered by ICD-9-CM based classification, are converted to SNOMED description of disease states.he researcher also created this auto-converter program.The clinical support object-oriented data-base, with its rich representation of semantics of data in hierarchies, can allow abstract level retrieval, such as "any patient who were prescribed xxx series antibiotics, with at least one time high record of GOT being more than 100." The researcher believes that this level of abstractness in clinical information retrieval has never before realized.The researcher hopes that HL7 implementation in Japanese hospitals would increase, following by this pioneer experiment, and that real semantic clinical support would realized in very near future.
