基于认知任务分析的急诊临床决策辅助系统设计与实施

Emergency clinical decision support system design and implementation based on cognitive task analysis

目的本试验拟采用认知任务分析的方法，总结和分析急诊医生诊疗过程中的关键环节，并指导急诊临床决策辅助系统的设计和实施。方法首先进行我院急诊信息系统的现况调查，形成初步的调研报告，整理急诊临床决策辅助系统建设中需要解决的关键问题。然后，采用认知任务分析的方法确定急诊临床决策关键环节的任务分析报告，提出改善急诊临床决策辅助系统设计方案并通过与东华软件公司的合作完成最终急诊临床决策辅助支持系统的搭建。结果我院目前还没有适合急诊的临床决策辅助系统，本研究透彻分析了急诊临床决策工作关键环节对于信息系统建设的核心需求，完成了急诊临床决策辅助系统的设计和实施，更好地服务于急诊临床。结论认知任务分析作为一种更为科学的任务分析方法在众多领域具有很好的应用前景，本研究首次将这一方法应用于急诊临床决策辅助系统的建设和实施过程中，使得急诊临床决策辅助系统的建设更加合理并具备良好的工作实用性。

Objective We use cognitive task analysis to summarize and analyze the key links in the emergency clinical work, and to guide the design and implementation of the emergency clinical decision support system. Methods Firstly, the current situation survey of hospital emergency department clinical decision support system was performed. We finished the preliminary investigation report, finishing the needs to address the key issues in the construction of emergency information. Secondly, we used the methods of cognitive task analysis to determine the key aspects of the task analysis report of the emergency clinical decision, proposed to improve the efficiency of emergency clinical work and to protect patient safety. Finally, we cooperated with the ＂Donghua＂ software company to complete the final structures of the emergency clinical decision support system. Results We finished a thorough analysis of the core needs of the emergency clinical decision work, found the key links for the information system construction, and completed the emergency clinical decision support system structures for the better services in the emergency clinical. Conclusion The cognitive task analysis as a more scientific task analysis method has good application prospects in many fields. This is the first time to apply the method on the emergency clinical decision support system construction and implementation process. We made the emergency clinical decision support system more reasonable and practical through the cognitive task analysis.
