目的 了解肿瘤患者家庭照护者的社会孤立感现状并分析其影响因素。 方法 采用方便抽样，于2020年10月至12月，采用一般情况调查表、患者报告结局测量信息系统中的社会健康相关简表和癌症患者报告结局的经济毒性量表对上海市、 杭州市3家三级甲等医院肿瘤内科病房的肿瘤患者家庭照护者进行问卷调查。 结果 110名肿瘤患者家庭照护者社会孤立简表总分为（32.39±11.71）分，35.5%照护者存在轻度至重度的社会孤立感。多元线性回归分析显示，婚姻状态、经济毒性、社会参与能力是社会孤立感的影响因素（均P＜0.05）。 结论 肿瘤患者照护者的社会孤立感处于轻度至重度之间不等。护理人员需重点关注未婚、离异或丧偶以及经济毒性较重、社会参与能力较差的照护者，以降低其社会孤立感，促进患者家庭的整体健康。

Objective To investigate the status quo of social isolation among cancer patients’ family caregivers,and analyze its influencing factors. Methods Convenient sampling was used to select cancer patients’ family caregivers from the Department of Medical Oncology in three tertiary hospitals in Shanghai and Hangzhou City from October to December,2020. The general information questionnaire,Patient-Reported Outcomes Measurement Information System -social health short forms,and comprehensive score for financial toxicity based on the patient-reported outcome measures were adopted for investigation. Results The total score of social isolation short form among the 110 cancer patients’ family caregivers was（32.39±11.71),and 35.5% of the caregivers reported mild to severe levels of social isolation.Multiple linear regression analysis showed that marital status,financial toxicity and social participation ability were the influencing factors of social isolation（all P＜0.05). Conclusions Social isolation of cancer patients’ caregivers is at the mild to severe levels. Nursing staff should pay special attention to those caregivers who are unmarried,divorced or widowed,with heavy financial toxicity and low ability of social participation,so as to reduce their level of social isolation and promote the overall health of patients’ family.
