The research status of central venous catheterization-associated thrombosis: a bibliometrics analysis

Background: Central venous catheters are associated with a significantly increased risk of venous thrombosis due to a variety of factors. This bibliometric study analyzed the current research status in the field of central venous catheterization associated thrombosis. Methods: Related literatures in the Science Citation Index Expanded (SCI-E) database were identified using the search terms "central venous catheter" and "thrombosis". The CiteSpace software was used to analysis literature data including country, institution, author, and journal distribution characteristics, as well as the use of keywords, and the number of times the country, institution, author, or journal were cited. Cooccurrence maps between countries, institutions, authors, and keywords were constructed. Results: A total of 2,810 related literature records were identified, with a total of 29,920 citations. The number of documents and the number of citations generally showed an increasing annual trend. These documents were mainly published from developed countries in Europe and North America, including USA, Britain, Italy, and France. Cooperation between institutions tended to be limited to the same country, and collaboration between authors tended to be within the same institutions. Keyword analysis demonstrated that in recent years, the research on thrombosis related to central venous catheterization has been more targeted, with an increasing focus on evidence-based medicine. Conclusions: Future research may focus more on the prevention, early diagnosis, and treatment of asymptomatic central venous catheterization-related thrombosis.
