摘要

背景：中国大陆公共卫生政策转型中的信息大流行是已知的；然而，医生的贡献尚未得到评价。本研究旨在评估医师在中国大陆新冠肺炎疫情信息传播中的作用，揭示其内容结构和时空特征。方法收集在新浪微博上影响力最大的医生账号的数据。原始内容收集时间为2022年3月1日至2023年10月1日。根据交叉验证的内容分析识别错误信息。进行了传播指数、时空和网络分析。结果显示，通过关键词搜索过滤432个账户的28218篇文章，432个账户中287个账户的28218篇文章中有5825篇（20.6%）被确定为与新冠病毒相关的内容，共抓取了236775篇文章。287个账户中的112个账户（39.0%）发布的5825个帖子中有640个（11.0%）被认定为错误信息，并被分为5大类型和6小类型。内部和外部账户之间的差异反映在错误信息类型的分布上。不同职业的传播者在类型上有不同的倾向，并观察到几种错误信息的再传播模式。社会网络分析显示传播者之间存在很强的相关性。解释据我们所知，本研究首次采用混合方法研究中国大陆医疗从业者作为信息传播媒介的特征。我们的研究表明，中国医生对社交媒体上的COVID-19信息流行做出了重大贡献。这可能加剧大流行后社会对医疗系统的不信任，可能对公共卫生产生深远影响。

Communication analysis of the COVID-19 infodemic by medical practitioners in China: A mixed methods study

Background

The infodemic during the public health policy transformation in Chinese mainland is known; however, the contributions of medical practitioners have not been evaluated. This study aimed to estimate the role of medical practitioners during the COVID-19 infodemic in Chinese mainland and reveal content structure and spatiotemporal features.

Methods

Data from medical practitioner accounts with the highest influence were collected from Sina-Weibo. Original contents were collected from March 1st, 2022 to October 1st, 2023. Misinformation were identified based on cross-validated content analysis. Propagation index, spatiotemporal and network analysis were performed.

Findings

A total of 236,775 posts were crawled, with 28,218 posts from 432 accounts filtered through a keyword search and 5825 out of 28,218 (20.6 %) posts from 287 out of 432 (66.4 %) accounts identified as COVID-19-related content. 640 out of 5825 (11.0 %) posts from 112 out of 287 (39.0 %) accounts were identified as misinformation and classified into 5 main types and 6 subtypes. Differences between internal and external accounts were reflected in the distribution of misinformation types. Propagators from various professions had different tendencies in terms of type, and several misinformation repropagation modes were observed. Social network analysis revealed strong correlations among propagators.

Interpretation

To our knowledge, this is the first mixed-methods study to examine the characteristics of medical practitioners as propagators in the infodemic in Chinese mainland. Our research suggested that Chinese medical practitioners significantly contributed to the COVID-19 infodemic in social media. This could exacerbate post-pandemic societal distrust in the medical system, potentially having far-reaching public health implications.

期刊介绍： Social Science & Medicine provides an international and interdisciplinary forum for the dissemination of social science research on health. We publish original research articles (both empirical and theoretical), reviews, position papers and commentaries on health issues, to inform current research, policy and practice in all areas of common interest to social scientists, health practitioners, and policy makers. The journal publishes material relevant to any aspect of health from a wide range of social science disciplines (anthropology, economics, epidemiology, geography, policy, psychology, and sociology), and material relevant to the social sciences from any of the professions concerned with physical and mental health, health care, clinical practice, and health policy and organization. We encourage material which is of general interest to an international readership.
