When medical data have been successfully recorded or exchanged between systems there appear a need to present the data consistently to ensure that it is clearly understood and interpreted. A standard based user interface can provide interoperability on the visual level.
The goal of this research was to develop, implement and evaluate an information model for building user interfaces for archetype based medical data.
The following types of knowledge were identified as important elements and were included in the information model: medical content related attributes, data type related attributes, user-related attributes, device-related attributes. In order to support flexible and efficient user interfaces an approach that represents different types of knowledge with different models separating the medical concept from a visual concept and interface realization was chosen. We evaluated the developed approach using Guideline for Good Evaluation Practice in Health Informatics (GEP-HI).
We developed a higher level information model to complement the ISO 13606 archetype model. This enabled the specification of the presentation properties at the moment of the archetypes' definition. The model allows realizing different users' perspectives on the data. The approach was implemented and evaluated within a functioning EHR system. The evaluation involved 30 patients of different age and IT experience and 5 doctors. One month of testing showed that the time required reading electronic health records decreased for both doctors (from average 310 to 220s) and patients (from average 95 to 39s). Users reported a high level of satisfaction and motivation to use the presented data visualization approach especially in comparison with their previous experience.
The introduced information model allows separating medical knowledge and presentation knowledge. The additional presentation layer will enrich the graphical user interface's flexibility and will allow an optimal presentation of medical data considering the different users' perspectives and different media used for data presentation.
当医疗数据在系统之间成功记录或交换后，就需要以一致的方式呈现数据，以确保其能被清晰理解和解读。基于标准的用户界面可以在视觉层面提供互操作性。
本研究的目标是开发、实施并评估一个用于构建基于原型的医疗数据用户界面的信息模型。
以下几类知识被确定为重要元素并纳入信息模型：与医疗内容相关的属性、与数据类型相关的属性、与用户相关的属性、与设备相关的属性。为了支持灵活高效的用户界面，我们选择了一种用不同模型表示不同类型知识的方法，将医学概念与视觉概念及界面实现分开。我们使用健康信息学良好评估实践指南（GEP-HI）对所开发的方法进行了评估。
我们开发了一个更高级别的信息模型来补充ISO 13606原型模型。这使得在原型定义时就能指定呈现属性。该模型允许实现不同用户对数据的视角。该方法在一个运行中的电子健康记录（EHR）系统中得到了实施和评估。评估涉及30名不同年龄和IT经验的患者以及5名医生。一个月的测试表明，医生读取电子健康记录所需的时间减少了（从平均310秒降至220秒），患者读取电子健康记录所需的时间也减少了（从平均95秒降至39秒）。用户报告称对使用所呈现的数据可视化方法非常满意，并且有很高的积极性，尤其是与他们之前的经验相比。
引入的信息模型允许将医学知识和呈现知识分开。额外的呈现层将丰富图形用户界面的灵活性，并能考虑到不同用户的视角和用于数据呈现的不同媒介，实现医疗数据的最佳呈现。
