目的 构建ICU高级实践护士核心能力评价指标体系，为ICU高级实践护士的培养及能力评价提供参考依据。 方法 基于文献分析法、半结构式访谈法，初步拟订ICU高级实践护士核心能力评价指标体系初稿，于2024年11月—2025年1月，采用德尔菲专家函询法系统构建指标体系内容，采用层次分析法计算各级指标权重，最终完成指标体系的构建。 结果 16名专家参加两轮函询，两轮问卷回收率分别为80%、100%，专家权威系数为0.904；两轮函询后一、二、三级指标肯德尔和谐系数分别为0.338、0.317、0.357，差异均具有统计学意义（P<0.05），最终形成包括5个一级指标、12个二级指标、36个三级指标构成的ICU高级实践护士核心能力评价指标体系。 结论 ICU高级实践护士核心能力评价指标体系科学性、可靠性良好，具有较好的实用性及推广价值，可为ICU高级实践护士的培训、选拔和能力评估提供一定的参考依据。

Objective To construct an evaluation index system for the core competencies of advanced practice nurses in the ICU，providing a reference basis for the training and ability evaluation of advanced practice nurses in the ICU. Methods Based on the literature analysis method and semi-structured interview method，the draft of the evaluation index system for the core competencies of advanced practice nurses in ICU was initially drafted. From November 2024 to January 2025，the Delphi expert consultation method was used to systematically construct the content of the evaluation index system for the core competencies of advanced practice nurses in ICU，and the analytic hierarchy process was adopted to calculate the weights of each level of indicators. Finally，the construction of the core competency evaluation index system for advanced practice nurses in the ICU was completed. Results A total of 16 experts participated in the two rounds of consultation. The recovery rates of the questionnaires in the two rounds were 80% and 100% respectively，and the expert authority coefficient is 0.904. After two rounds of consultation，the harmony coefficient of the first-level indicator was 0.338，that of the second-level indicator was 0.317，and that of the third-level indicator was 0.357，the differences were all statistically significant（P<0.05）. Ultimately，a core competency evaluation index system for advanced practice nurses in the ICU was formed，consisting of 5 first-level indicators，12 second-level indicators，and 36 third-level indicators. Conclusion The core competency evaluation index system for ICU advanced practice nurses is scientific and reliable，with good practicality and promotion value. It can provide a reference for the training，selection，and competency evaluation of ICU advanced practice nurses.
