Introduction

Acinetobacter baumannii is one of the most common and effective pathogens in causing serious ICU infections in modern hospital systems around the world (1- 5). This hospital pathogen has caused a wide range of infections, including Septicemia and Pneumonia, and has become a significant challenge in health care services, especially hospitals (3,6-8). A. baumannii researchers and specialists have always conducted extensive research in various fields due to the challenges, crises, and global impact of this pathogen.
Co-citation analysis is one of the scientometric techniques that is used as a method in analyzing the intellectual structure of scientists and their publications and identifying principal authors and publications in different areas of research (15,14). Due to the importance of the scientometrics study of A. baumannii's international publications, the main issue of this article is to visualize the scientific collaboration network and the citations of A. baumannii's researchers using the methods of co-citation analysis and social network analysis from 1990 to 2019. Conducting such research and its practical results will be of great help to researchers and planners of the healthcare system in the field of strategic and heuristic planning, as well as the implementation of programs at the level of medical sciences organizations and countries (20).
Therefore, it seems necessary to conduct practical, comprehensive, and analytical research in this regard. Visualizing the researchers of A. Baumannii's scientific collaboration network is the primary goal of this study.

Materials and Methods

The method used in this paper is co-citation analysis. The statistical population is all A. Baumannii indexed publications from 1990 to 2019 in the Web of Science Core Collection (WOSCC). A total of 4473 records were retrieved after an advanced search for "A. Baumannii" with the "TI" tag using Ravar PreMap, UCINET 6.528.0.0, and Netdraw 1.0.0.0 for preprocessing and analyzing the data .(18)

Results

The Growth Trend of Acinetobacter baumannii Publications
A. baumannii's number of Publications rose from 2 in 1990 to 475 in 2019. The data in Figure 1 showed that A. baumannii's publication trend has been growing in the last three decades.

Ranking of Acinetobacter baumannii's Top Journals Based on IF
The data in Table 1 showed that the best journal is "Clinical Infectious Diseases," with an impact factor of 9.05.

The Most Effective Acinetobacter baumannii Researchers
With 4365 citations, "Seifert, Harald" from Germany and affiliated with University Hospital of Cologne, ranked first among the most effective researchers in the A. Baumannii research domain (Table 2).

Discussion

The trend of scientific publications of A. Baumannii researchers has been growing in the last three decades. The results of this part of the study are consistent with the results of research by Zeinoun (22), Liao (28), Sweileh (31). "Seifert, Harald" is the most influential researcher, and "Bonomo, Robert A" is the most proliferated one. These results are not consistent with the results of Figg (41) and Huamani (42) but are consistent with the research of Hassanzadeh et al. (30). "Seifert, Harald * Higgins, Paul G," is a co-citation pair who share common research interests.
"Beceiro, Alejandro" has more power in the knowledge flow of network and has a unique role in attracting new researchers to the scientific network (17). "HSU Li Yang," due to its central position in the network, has many relationships with other researchers and has an important strategic position in the overall structure of the collaboration network (17, 40). "Seifert, Harald," with the highest closeness centrality, is closer to other members of the network and has faster access to all researchers on the network than any other so that there can be more citations to his publications (17,39). From this perspective, the results of the present study are consistent with the research of Soheili et al. (37).

Conclusion

One of the most critical concepts and unique functions of social network analysis is the study of researchers' scientific collaboration network with centrality indicators that determine the importance and effectiveness of researchers and their performance in the cooperation network. Based on this, it is suggested that detailed and independent research of the Iranian A. baumannii researchers’ collaboration network be conducted.
