Evolution of military medicine literature: A scientometric study of global publications on military medicine between 1978 and 2017

Abstract

Objectives: Scientometrics is a popular statistical discipline providing data relevant to publication patterns and trends in a certain academic field. There are no scientometric analyses of publications produced in military medicine literature. The present study aims to perform a holistic analysis of military medicine literature. Methods: All data of this study were collected from the Web of Science Core Collection. All indexed documents between 1978 and 2017 were included. Countries, authors, institutions, citations and keywords relevant to the military medicine literature were comprehensively analysed. An infomap revealing global productivity and infographics of scientometric networks were generated. Results: A total of 48 240 published items were found, 82.29% of which were original articles. USA, covering 56.66% of all literature dominated the military medicine field followed by the UK, China, Canada and Israel. We found that 18 of 20 most productive institutions in the world were from USA and the US Department of Defense was the most contributing institution in the literature with 9664 documents. The most used keywords over a 40-year period were 'military', 'veterans', 'posttraumatic stress disorder' and 'military personnel'. A scientometric network of keywords showed a complicated 'starburst pattern'. Conclusion: All most contributing countries except Turkey, China and Israel were developed nations. Only one institution (Tel Aviv University) from developing countries was noted in the list of 20 most productive institutions. The researchers from developing and the least developed countries should be encouraged and supported to carry out novel studies on military medicine. © Author(s) (or their employer(s)) 2019.
