An automated practitioner order entry system was recently implemented at the VA Puget Sound Health Care System. Since the introduction of this system, we have experienced various problems, among them an increase in time required for practitioners to enter orders. In order to improve usability and acceptance of the order entry, an alternate pathway was built within CPRS that allows direct natural language based order entry. Implementation of the extension in CPRS has been made possible because of the three layers CPRS architecture and its strong object oriented models. This paper discusses the advantages and needs for a natural language based order entry system and its implementation within an existing order entry system.
退伍军人事务部普吉特海湾医疗保健系统最近实施了一个自动化的医生医嘱录入系统。自从引入这个系统以来，我们遇到了各种问题，其中包括医生录入医嘱所需时间增加。为了提高医嘱录入的可用性和接受度，在CPRS中构建了一条替代途径，允许基于自然语言的直接医嘱录入。由于CPRS的三层架构及其强大的面向对象模型，得以在CPRS中实现该扩展。本文讨论了基于自然语言的医嘱录入系统的优势和需求，以及在现有医嘱录入系统中的实现。
