目的 基于社会生态系统理论，探讨ICU患者、家属及医护人员在患者住院期间情感支持的体验和期望，为制订ICU患者心理及情感支持方案提供参考依据。方法 按照描述性质性研究，采用目的抽样法，选取2023年9月15日—11月15日在南通市某三级甲等医院重症医学科就诊的12组患者、家属及其诊疗医护人员作为研究对象，对其进行半结构式深度访谈，采用内容分析法对资料进行分析、归纳并提炼主题。结果 基于社会生态系统理论模型，共归纳出3个主题。①宏观系统：ICU以挽救生命、治疗疾病为主要任务，对患者情感的关注和支持不足，以致重视生命长度还是质量的社会观点冲突。②中观系统：患者和家属对ICU治疗环境及方式有陌生感、恐惧感，医护人力紧张且对情感支持认知欠缺，造成患者情感需求被忽视。③微观系统：由于个体差异，每例患者或家属的情感需求不同，每名医护人员表达情感方式不同。结论 ICU患者及家属在住院期间对情感支持有较高的需求和期待，但往往由于自身及外界环境等因素导致心理需求不能得到满足。临床医护人员可尝试改善ICU“软环境”，构建“患者-医护人员-家属”共同参与的人文关怀护理模式，借助智能化网络平台采取合适的人文关怀措施，提高患者及家属情感支持的获得感。

Objective To explore the experience and expectation of emotional support of ICU patients，their family members and medical staff during hospitalization based on the social ecological system theory，so as to provide a reference for formulating psychological and emotional support programs for ICU patients. Methods According to the descriptive qualitative research，using the purposive sampling method，12 groups of patients，family members and medical staff who were treated in the Department of Critical Care Medicine of a Class Ⅲ Grade A hospital in Nantong from September 15，2023 to November 15，2023 were selected as the research objects，and semi-structured in-depth interviews were conducted. The content analysis method was used to analyze，summarize and refine the data. Results Based on the social ecological system theoretical model，a total of 3 themes were summarized：①Macro system：the main task of ICU is to save lives and treat diseases，but the lack of attention and support for patients’ emotions leads to social conflicts between focusing on the length or quality of life of patients；②Meso-system：patients and their family members had strangeness and fear of the ICU treatment environment and methods，and the shortage of medical staff and lack of understanding of emotional support have led to the neglect of patients’ emotional needs；③Micro-system：due to individual differences，each patient or family member has different emotional needs，and each medical staff has different ways of expressing emotions. Conclusion ICU patients and their family members have high needs and expectations for emotional support during hospitalization，but their psychological needs are often not met due to their own and external environment and other factors. Clinical medical staff can try to improve the “soft environment” of ICU，build a humanistic care nursing model involving “patients，medical staff，and family members”，and use intelligent network platforms to take appropriate humanistic care measures to enhance the sense of emotional support for patients and family members.
