Background:
Abdominal solid organ transplant (SOT) programs have been hit hard by the COVID-19 pandemic, which was officially declared as such on March 11, 2020. Over two years, the tightening and softening of limitations in response to the "waves" of infection and COVID-19 fluctuations have provided distinct issues for waitlisted patients, transplant recipients, and transplant organizations.
Method:
We searched Scopus using the terms "transplant" and "transplantation," and organ-related phrases like "intestin*," "liver," "kidney," "hepatic," "renal," and "pancrea*," as well as COVID-19 terms such as "COVID-19," "coronavirus," and "SARS-CoV-2." We included articles, reviews, conference papers, letters, notes, editorials, brief surveys, book chapters, and errata and studied nations, institutions, authors, journals, keywords, and articles. VOSviewer 1.6.18 and Excel were used to create tables and figures.
Results:
We included 1,251 of 1,256 studies. Among them, 289 (23.1%), 489 (39.1%), and 473 (37.8%) papers were published in 2020, 2021, and 2022, with mean (SD) citations of 30.3 (53.3), 14.3 (26.8), and 4.79 (6.38), respectively. Compared to other abdominal organs, the field of kidney transplants had the highest number of articles describing the impact of COVID-19. The United States contributed the most articles, and the American Journal of Transplantation published the most articles.
Conclusion:
To our knowledge, this is the first bibliometric investigation of the impact of COVID-19 on SOT. This report provides an overview of the research conducted on SOT and COVID-19. There is potential for this bibliometric analysis to serve as a beneficial and practical resource for ongoing and future research.
Insights
The COVID-19 pandemic significantly impacted solid organ transplant (SOT) programs worldwide. This bibliometric analysis reveals a surge in research on SOT and COVID-19, particularly concerning kidney transplants.
Area of Science:
- Transplant Surgery
- Infectious Diseases
- Bibliometrics
Background:
- The COVID-19 pandemic created significant challenges for solid organ transplant (SOT) programs globally.
- Fluctuating restrictions and infection waves impacted waitlisted patients, recipients, and transplant organizations.
Purpose of the Study:
- To conduct the first bibliometric investigation on the impact of COVID-19 on SOT.
- To provide an overview of research trends and key areas in SOT and COVID-19 studies.
Main Methods:
- A comprehensive literature search was performed on Scopus using keywords related to transplantation and COVID-19.
- Included various publication types (articles, reviews, etc.) and analyzed nations, institutions, authors, journals, and keywords.
- VOSviewer and Excel were utilized for data analysis and visualization.
Main Results:
- 1,251 studies were included, with publication numbers peaking in 2021.
- Kidney transplantation research was most prominent compared to other abdominal organs.
- The United States led in publications, and the American Journal of Transplantation was the most frequent source.
Conclusions:
- This bibliometric analysis offers a foundational understanding of research on COVID-19's impact on SOT.
- It serves as a valuable resource for current and future research in the field.
- Highlights the extensive research output and focus on kidney transplants during the pandemic.
