全球 COVID-19 护理相关研究趋势：文献计量分析。

BACKGROUND: Coronavirus disease 2019 (COVID-19) has significantly impacted healthcare, especially the nursing field. This study aims to explore the current status and hot topics of nursing-related research on COVID-19 using bibliometric analysis. METHODS: Between 2019 and 2022, publications regarding nursing and COVID-19 were retrieved from the Web of Science core collection. We conducted an advanced search using the following search query string: TS = ("Novel coronavirus 2019" or "Coronavirus disease 2019" or "COVID 19" or "2019-nCOV" or "SARS-CoV-2" or "coronavirus-2") and TS = ("nursing" or "nurse" or "nursing-care" or "midwife"). Bibliometric parameters were extracted, and Microsoft Excel 2010 and VOSviewer were utilized to identify the largest contributors, including prolific authors, institutions, countries, and journals. VOSviewer and CiteSpace were used to analyze the knowledge network, collaborative maps, hotspots, and trends in this field. RESULTS: A total of 5,267 papers were published between 2020 and 2022. The findings are as follows: the USA, China, and the UK are the top three prolific countries; the University of Toronto, the Harvard Medical School, the Johns Hopkins University, and the Huazhong University of Science & Technology are the top four most productive institutions; Gravenstein, Stefan, and White, Elizabeth M. from Brown University (USA) are the most prolific authors; The International Journal of Environmental Research and Public Health is the most productive journal; "COVID-19," "SARS-CoV-2," "nurse," "mental health," "nursing home," "nursing education," "telemedicine," "vaccine-related issues" are the central topics in the past 2 years. CONCLUSION: Nursing-related research on COVID-19 has gained considerable attention worldwide. In 2020, the major hot topics included "SARS-CoV-2," "knowledge," "information teaching," "mental health," "psychological problems," and "nursing home." In 2021 and 2022, researchers were also interested in topics such as "nursing students," "telemedicine," and "vaccine-related issues," which require further investigation.

背景：2019 年冠状病毒病（COVID-19）对医疗保健产生了重大影响，尤其是护理领域。本研究旨在使用文献计量分析方法探讨 COVID-19 相关护理研究的现状和热点。

方法：2019 年至 2022 年，从 Web of Science 核心集检索有关护理和 COVID-19 的出版物。我们使用以下高级搜索查询字符串进行高级搜索：TS=（“新型冠状病毒 2019”或“冠状病毒病 2019”或“COVID-19”或“2019-nCOV”或“SARS-CoV-2”或“冠状病毒-2”）和 TS=（“护理”或“护士”或“护理保健”或“助产士”）。提取文献计量学参数，并使用 Microsoft Excel 2010 和 VOSviewer 确定最大贡献者，包括多产作者、机构、国家和期刊。使用 VOSviewer 和 CiteSpace 分析该领域的知识网络、合作图谱、热点和趋势。

结果：2020 年至 2022 年期间共发表了 5267 篇论文。研究结果如下：美国、中国和英国是前三大高产国家；多伦多大学、哈佛医学院、约翰霍普金斯大学和华中科技大学是前四大最具生产力的机构；布朗大学的 Gravenstein、Stefan 和 White、Elizabeth M.是最具生产力的作者；国际环境研究与公共卫生杂志是最具生产力的期刊；“COVID-19”、“SARS-CoV-2”、“护士”、“心理健康”、“养老院”、“护理教育”、“远程医疗”、“疫苗相关问题”是过去 2 年的核心主题。

结论：全球范围内对 COVID-19 相关护理研究的关注度很高。2020 年，主要热点包括“SARS-CoV-2”、“知识”、“信息教学”、“心理健康”、“心理问题”和“养老院”。2021 年和 2022 年，研究人员还对“护理学生”、“远程医疗”和“疫苗相关问题”等主题感兴趣，这些主题需要进一步研究。
