Insights
This bibliometric study analyzed research on heart and lung transplantation during the COVID-19 pandemic. The United States led publications, with the Journal of Heart and Lung Transplantation being the primary venue.
Area of Science:
- Transplantation Research
- Infectious Disease Impact
- Bibliometrics
Background:
- Coronavirus disease 2019 (COVID-19) pandemic significantly affected heart and lung transplant programs globally.
- Impacts included donor availability, patient care, and resource allocation.
- This study reviews research output to understand the transplant community's response.
Purpose of the Study:
- To assess the impact of COVID-19 on heart and lung transplantation research.
- To identify key themes, contributions, and trends in the scientific literature during the pandemic.
- To provide a visual analysis of research output.
Main Methods:
- Bibliometric analysis of the Web of Science database (March 2020 - February 2023).
- Keywords included "transplant", "heart", "lung", and COVID-19 related terms.
- Data analyzed included authors, journals, countries, institutions, and publication types; visualized using VOSviewer.
Main Results:
- 847 research items were included, with 392 articles and 88 reviews.
- The United States was the leading country for publications (317) and citations (4948).
- The Journal of Heart and Lung Transplantation published the most papers (101).
Conclusions:
- This is the first bibliometric study offering a visual analysis of COVID-19's impact on heart and lung transplantation.
- The study provides an overview of current research hotspots.
- It aims to predict future research frontiers in the field.
Background:
Since being declared as a pandemic on March 11, 2020, coronavirus disease 2019 (COVID-19) has profoundly influenced heart and lung transplant programs, impacting donor availability, patient management, and healthcare resources. This study offers a citation-based review of the research output on this subject, seeking to understand how the transplant community has responded to these challenges. Through a review of literature from the beginning of the pandemic to early 2023, we evaluate the shifts in academic emphasis and the emerging trends in heart and lung transplantation during the COVID-19 period.
Aim:
To assess the impact of COVID-19 on heart and lung transplantation research, highlighting key themes, contributions, and trends in the literature during the pandemic.
Methods:
We conducted an extensive search of the Web of Science database on February 9, 2023. We employed the terms "transplant" and "transplantation", as well as organ-specific terms like "heart", "cardiac", and "lung", combined with COVID-19-related terms such as "COVID-19", "coronavirus", and "SARS-CoV-2". The search encompassed publications from March 11, 2020 to February 9, 2023. Data on authors, journals, countries, institutions, and publication types (articles, reviews, conference papers, letters, notes, editorials, brief surveys, book chapters, and errata) were analyzed. The data was visualized and processed with VOSviewer 1.6.18 and Excel.
Results:
We included 847 research items. There were 392 articles (46.3%) and 88 reviews (10.3%). The studies included were referenced 7757 times, with an average of 9.17 citations per article. The majority of the publications (n = 317) were conducted by institutes from the United States with highest citations (n = 4948) on this subject, followed by Germany, Italy, and France. The majority of papers (n = 101) were published in the Journal of Heart and Lung Transplantation.
Conclusion:
To the fullest extent of our knowledge, this is the first bibliometric study of COVID-19's impact on heart and lung transplantation to offer a visual analysis of the literature in order to predict future frontiers and provide an overview of current research hotspots.
