To identify core challenges and first steps on the way to sustainable information systems in healthcare.
Recent articles on healthcare information technology and related articles from Medical Informatics and Computer Science were reviewed and analyzed. Core challenges that couldn't be solved over the years are identified.
The two core problem areas are process integration, meaning to effectively embed IT-systems into routine workflows, and systems integration, meaning to reduce the effort for interconnecting independently developed IT-components. Standards for systems integration have improved a lot, but their usefulness is limited where system evolution is needed.
Sustainable Healthcare Information Systems should be based on system architectures that support system evolution and avoid costly system replacements every five to ten years. Some basic principles for the design of such systems are separation of concerns, loose coupling, deferred systems design, and service oriented architectures.
确定医疗保健领域可持续信息系统建设过程中的核心挑战及首要步骤。
对近期关于医疗信息技术的文章以及来自医学信息学和计算机科学领域的相关文章进行了综述与分析。识别出多年来一直未能解决的核心挑战。
两个核心问题领域分别是流程整合，即有效地将信息技术系统嵌入日常工作流程；以及系统整合，即减少独立开发的信息技术组件之间互连的工作量。系统整合标准虽有很大改进，但在需要系统演进的情况下其效用有限。
可持续的医疗保健信息系统应基于支持系统演进的系统架构，避免每五到十年就进行代价高昂的系统更换。设计此类系统的一些基本原则包括关注点分离、松耦合、延迟系统设计和面向服务的架构。
