The economic and organizational impact of imposing state-of-the-art technology to the large number of proprietary legacy systems operational in most hospitals requires integrated clinical professional workstations to provide flexible encapsulation mechanisms for these systems rather than reengineering these systems to this new technology. In this paper the implications of different input/output and translation models of legacy systems for their integration into a clinical workstation is described. Examples of legacy systems that have been integrated in the HERMES clinical workstation are presented as examples of the range of difficulties one might encounter. The features that an integrated workstation should offer for integrating a broad range of legacy systems are also addressed in this paper.
在大多数医院中，将最先进技术应用于大量运行的专有遗留系统所产生的经济和组织影响，需要集成临床专业工作站为这些系统提供灵活的封装机制，而不是将这些系统重新设计以适应这项新技术。本文描述了遗留系统不同的输入/输出和转换模型对于其集成到临床工作站的影响。作为可能遇到的一系列困难的示例，展示了已集成到HERMES临床工作站的遗留系统实例。本文还讨论了集成工作站为集成广泛的遗留系统应具备的功能。
