目的 探究ICU护士维护老年患者尊严的影响因素，构建概念框架，为改进护理实践提供参考。 方法 采用程序化扎根理论方法，于2024年3月—5月，在长沙市3所三级甲等医院与15名ICU护士进行半结构化访谈，并运用NVivo软件对资料进行三级编码。 结果 共提炼出29个初始概念，形成9个主轴编码，最终归纳出4个核心范畴：护士因素、患者因素、文化因素和管理因素。基于范畴之间的内在逻辑关系，构建了ICU护士维护老年患者尊严影响因素的概念框架。 结论 ICU老年患者尊严的维护需要通过加强护士培训、优化资源配置、推动多学科协作并提升文化敏感性，进而建立有利于尊严护理的环境。

Objective To explore the influencing factors of ICU nurses maintaining the dignity of elderly patients， to construct a conceptual framework and provide evidence for improving nursing practice. Methods A programmatic grounded theory approach was adopted. From March to May 2024，semi-structured interviews were conducted with 15 ICU nurses from three tertiary class A hospitals in Changsha. Data were analyzed using Nvivo software through three levels of coding. Results A total of 29 initial concepts were extracted，forming 9 axial codes，and ultimately 4 core categories were summarized，including nurse factors，patient factors，cultural factors，and management factors. A conceptual framework was constructed based on the intrinsic logical relationships among these categories. Conclusion Maintaining elderly patient dignity in the ICU requires strengthening nurse training，optimizing resource allocation，promoting multidisciplinary collaboration，and enhancing cultural sensitivity to establish a dignity-centered care environment.
