OBJECTIVE
Develop a model for structured and encoded representation of medical information that supports human review, decision support applications, ad hoc queries, statistical analysis, and natural-language processing.
DESIGN
A medical information representation model was developed from manual and semiautomated analysis of patient data. The key assumption of the model is that medical information can be represented as a series of linked events. The event representation has two main components. The first component is a frame or template definition that specifies the attributes of the event. The second component is a structured vocabulary, the terms of which are taken as the values of the slots in the event template structure. Individual event instances are linked by specific named relationships.
RESULTS
The proposed model was used to represent a chest-radiograph report.
CONCLUSIONS
The event model of medical information representation provides a mechanism for formal definition of the logical structure of medical data and allows explicit time-oriented and associative relationships between event instances.
目的
开发一种用于医学信息结构化和编码表示的模型，以支持人工审核、决策支持应用、即席查询、统计分析和自然语言处理。
设计
通过对患者数据进行人工和半自动分析，开发了一种医学信息表示模型。该模型的关键假设是医学信息可以表示为一系列相互关联的事件。事件表示有两个主要组成部分。第一个组成部分是一个框架或模板定义，它指定了事件的属性。第二个组成部分是一个结构化词汇表，其术语被用作事件模板结构中插槽的值。各个事件实例通过特定的命名关系链接在一起。
结果
所提出的模型被用于表示一份胸部X光报告。
结论
医学信息表示的事件模型为医学数据逻辑结构的形式化定义提供了一种机制，并允许事件实例之间存在明确的面向时间和关联的关系。
