目的 系统整合ICU医护人员实施安宁疗护影响因素的质性研究。 方法 计算机检索PubMed、Web of Science、Cochrane Library、Embase、CINAHL、中国知网、万方数据库、维普数据库、中国生物医学文献数据库中有关ICU医护人员实施安宁疗护影响因素的质性研究，检索时限为建库至2024年9月1日。2名研究者独立进行文章筛选和数据提取。采用澳大利亚乔安娜布里格斯研究所循证卫生保健中心的质性研究质量评价工具（2016版）进行文献质量评价。采用汇集性整合方法整合结果。 结果 共纳入14篇文献，提炼出53个研究结果，将相似结果归纳为9个新类别，整合形成3个结果：ICU医护人员实施安宁疗护的促进因素、ICU医护人员实施安宁疗护的阻碍因素、外部环境因素。 结论 ICU医护人员实施安宁疗护受多方面因素的影响，医院管理者应构建良好的内部支持系统，加强医护人员的培训和支持，克服外部阻碍，建立健全安宁疗护管理制度和机制，为ICU患者提供更加优质的安宁疗护服务。

Objective To systematically integrate the qualitative studies on the influencing factors of palliative care implemented by ICU medical staff. Methods PubMed，Web of Science，Cochrane Library，Embase，CINAHL，CNKI，Wanfang Database，VIP，and CBM were searched for qualitative studies on the influencing factors of palliative care implemented by ICU medical staff from inception to September 1，2024. Two investigators independently screened articles and extracted data. The Qualitative Research Quality Assessment Tool（2016 Edition） of the Centre for Evidence-Based Health Care at the Joanna Briggs Institute in Australia was used to evaluate the quality of the literature. The results were integrated by a pooled integration approach. Results A total of 14 articles were included，and 53 research results were extracted，and the similar results were summarized into 9 new categories. Three results were integrated，including the promoting factors of ICU medical staff to implement palliative care，the hindrance factors of ICU medical staff to implement palliative care，and the external environmental factors. Conclusion The implementation of palliative care by ICU medical staff is affected by many factors，and hospital managers should build a good internal support system，strengthen the training and support of medical staff，overcome external obstacles，establish and improve the palliative care management system and mechanism，and provide better palliative care services for ICU patients.
