Patient Data Management Systems (PDMS) for ICUs collect, present and store clinical data. Various intentions make analysis of those digitally stored data desirable, such as quality control or scientific purposes. The aim of the Intensive Care Data Evaluation project (ICDEV), was to provide a database tool for the analysis of data recorded at various ICUs at the University Clinics of Vienna.
General Hospital of Vienna, with two different PDMSs used: CareVue 9000 (Hewlett Packard, Andover, USA) at two ICUs (one medical ICU and one neonatal ICU) and PICIS Chart+ (PICIS, Paris, France) at one Cardiothoracic ICU. CONCEPT AND METHODS: Clinically oriented analysis of the data collected in a PDMS at an ICU was the beginning of the development. After defining the database structure we established a client-server based database system under Microsoft Windows NI and developed a user friendly data quering application using Microsoft Visual C++ and Visual Basic;
ICDEV was successfully installed at three different ICUs, adjustment to the different PDMS configurations were done within a few days. The database structure developed by us enables a powerful query concept representing an 'EXPERT QUESTION COMPILER' which may help to answer almost any clinical questions. Several program modules facilitate queries at the patient, group and unit level. Results from ICDEV-queries are automatically transferred to Microsoft Excel for display (in form of configurable tables and graphs) and further processing.
The ICDEV concept is configurable for adjustment to different intensive care information systems and can be used to support computerized quality control. However, as long as there exists no sufficient artifact recognition or data validation software for automatically recorded patient data, the reliability of these data and their usage for computer assisted quality control remain unclear and should be further studied.
重症监护病房（ICU）的患者数据管理系统（PDMS）收集、呈现和存储临床数据。出于各种目的，对这些数字存储的数据进行分析很有必要，比如质量控制或科研目的。重症监护数据评估项目（ICDEV）的目的是提供一个数据库工具，用于分析维也纳大学诊所各重症监护病房记录的数据。
维也纳总医院，使用了两种不同的PDMS：两个重症监护病房（一个内科重症监护病房和一个新生儿重症监护病房）使用CareVue 9000（美国安多弗的惠普公司），一个心胸外科重症监护病房使用PICIS Chart+（法国巴黎的PICIS公司）。概念与方法：对重症监护病房的PDMS收集的数据进行以临床为导向的分析是开发工作的开端。定义数据库结构后，我们在Microsoft Windows NT下建立了一个基于客户端-服务器的数据库系统，并使用Microsoft Visual C++和Visual Basic开发了一个用户友好的数据查询应用程序。
ICDEV已成功安装在三个不同的重症监护病房，在几天内完成了对不同PDMS配置的调整。我们开发的数据库结构实现了一个强大的查询概念，即“专家问题编译器”，它几乎可以帮助回答任何临床问题。几个程序模块便于在患者、组和科室层面进行查询。ICDEV查询的结果会自动传输到Microsoft Excel中进行显示（以可配置的表格和图表形式）以及进一步处理。
ICDEV概念可进行配置以适应不同的重症监护信息系统，并可用于支持计算机化质量控制。然而，只要不存在足够的伪像识别或数据验证软件来处理自动记录的患者数据，这些数据的可靠性及其在计算机辅助质量控制中的用途仍不明确，应进一步研究。
