调查居家肾移植受者对新型冠状病毒肺炎(COVID-19)的认知、态度和行为现状，并分析其影响因素。

对树兰(杭州)医院随访信息系统中2018年4月至2019年12月接受肾移植的受者进行整群调查。调查问卷包含两部分：(1)受者一般资料，包括性别、年龄、肾移植术后时间、受教育程度和居住地等；(2)COVID-19知信行部分包含3个维度共计25个条目，内容包括对COVID-19的认知和态度以及个人防护措施，各条目均应用Likert 4级评分法。收集纳入受者的临床信息，采用在线问卷调查平台和电话两种方式进行调查。采用t检验或方差分析比较不同性别、年龄、受教育程度、术后时间以及居住地的受者COVID-19知信行3个维度得分和总分；采用多元线性回归进行影响知信行总分的多因素分析。

共收到问卷245份，其中电话调查52例，使用在线问卷调查平台193例；有效问卷239份，有效率97.55%。239例肾移植受者COVID-19知信行总分为(81.2±8.1)分，其中知识、态度和行为维度得分分别为(32.3±4.5)、(21.9±1.8)和(26.9±3.6)分。单因素分析结果显示，年龄、受教育程度和居住地不同的肾移植受者知识维度得分差异均有统计学意义(P均<0.05)；受教育程度、术后时间和居住地不同的肾移植受者态度维度得分差异均有统计学意义(P均<0.05)；居住地不同的肾移植受者行为得分差异有统计学意义(P<0.05)。多因素分析结果显示，居住地是肾移植受者COVID-19知信行总分的影响因素(P<0.05)。

在COVID-19疫情期间，肾移植中心需有针对性的加强随访力度、方向以及增加健康教育的方式方法，重点关注老年、受教育程度较低以及居住在农村的肾移植受者。

To investigate the current status of cognition, attitude and behavior towards Corona Virus Disease 2019 (COVID-19) in home kidney transplant recipients and analyze the influencing factors.

A cluster survey was conducted among recipients who received kidney transplantation from April 2018 to December 2019 in the follow-up information system of Shulan (Hangzhou) Hospital. The questionnaire contained two parts: (1) the general data of recipients, including sex, age, time after kidney transplantation, education and residence; (2) the COVID-19 knowledge-attitude-practice part contained 25 items in three dimensions, including cognition and attitude towards COVID-19 and personal protective measures, each of which applied the Likert 4-level scoring method. The clinical information of the included recipients was collected and investigated using an online questionnaire platform or telephone. T-test or ANOVA was used to compare the COVID-19 knowledge bank three dimension scores and total scores of recipients with different sex, age, education, postoperative time, and residence; multiple linear regression was used for multivariate analysis affecting the knowledge bank total score.

A total of 245 questionnaires were received, including 52 telephone surveys, 193 online questionnaire platforms, and 239 valid questionnaires, with an effective rate of 97.55%. The total scores of COVID-19 knowledge and behavior in 239 kidney transplant recipients were (81.2±8.1) points, of which the scores of knowledge, attitude and behavior dimensions were (32.3±4.5), (21.9±1.8) and (26.9±3.6) points, respectively. The results of univariate analysis showed that there were significant differences in the knowledge dimension scores of kidney transplant recipients with different age, education and residence (all P<0.05); there were significant differences in the attitude dimension scores of kidney transplant recipients with different education, operative time and residence (all P<0.05); and there were significant differences in the behavior scores of kidney transplant recipients with different residence (P<0.05). The results of multivariate analysis showed that residence was a factor influencing the total score of COVID-19 knowledge in kidney transplant recipients (P<0.05).

During the epidemic period of COVID-19, kidney transplant centers should strengthen the follow-up intensity, direction and the way and method of increasing health education, focusing on kidney transplant recipients who are elderly, have less education and live in rural areas.
