儿童中心静脉置管维护标准化知识库及决策支持方案构建

Construction of pediatric CVC standardized maintenance knowledge base and decision support scheme

目的构建儿童中心静脉导管维护标准化编码知识库,根据知识库各条目具体内容设置相应的决策支持逻辑,旨在提高护士循证实践依从性,促进证据临床转化。方法循证法检索儿童中心静脉导管维护证据,提取具体维护措施后以临床护理分类为工具进行标准化编码,邀请导管维护领域专家对知识库各条目进行临床调适,形成知识库终稿后根据护理决策支持系统的功能设计决策支持方案。结果构建具有21项内容的标准化编码知识库,形成包括自动触发、智能推送、模板生成、自动关联、提醒/警告5种功能的决策支持方案。结论构建儿童中心静脉导管维护标准化编码知识库,可辅助护士作出临床决策,促进循证证据的高效转化和临床传播。

Objective To construct a pediatric CVC maintenance standardized knowledge base,to design the system logical function for each item of the knowledge base,to improve nurses′evidence-based practice and to boost evidence implementation.Methods We searched for literature on pediatric CVC maintenance per evidence-based methodology and extracted the particulars regarding maintenance measures,which were coded in standardized terminology in pursuant to clinical nursing classification system.Then we held expert panel discussions with the attendance of experts specialized in catheter maintenance for revision of the knowledge base and made the items suitable for clinical workflow.When the base was finalized,we designed decision support schemes in conformity with the function of nursing decision support system.Results A knowledge base that contains 21 pieces of evidence was constructed,and a 5-solution clinical decision support scheme,which includes automatic trigger,intelligent push,template generation,automatic association,reminder/warning,was formed.Conclusion Construction of the pediatric CVC standardized maintenance know-ledge base helps nurses make clinical decisions,and boost efficient evidence implementation and transmission.
