Analysis of directions of scientific research in foreign articles on underwater medicine, using VOSviewer program

OBJECTIVE. Improve scientists’ information capabilities by analyzing directions of scientific research in foreign articles on underwater medicine, using VOSviewer program, in 20 years from 2003 to 2022.

MATERIALS AND METHODS. The search query (Submarine Medicine) OR (Diving medicine) in PubMed bibliographic reference database provided 2476 responses to scientific articles, published in 2003–2022. The created array of publications in «.txt» format was uploaded to analysis program VOSviewer 1.6.20, capable of quick recognizing patterns in a huge array of bibliographic data. There were 6786 keywords in the array of articles. In recording 10 repetitions of keywords in articles, they became 358, being grouped into 7 clusters.

RESULTS. Cluster 1, named diving medicine, included 24,8 % of articles with the mutual association of 23,9 % of the total array. A large number of keyword associations with the terms in the other clusters was revealed. Cluster 2, dubbed the “experimental animal studies”, had 17,3 % of articles with the mutual association of 19,8 %, in cluster 3 – decompression sickness – 12 % and 13 %, in cluster 4 – problems of hypoxia effect on the body’s functional reserves from the standpoint of evidence-based medicine – 11,5 % and 12,8 %, in cluster 5 – hyperbaric oxygenation – 13,5 and 12,6 %, in cluster 6 – the use of evidence-based methods in research on underwater medicine – 12,8 % and 11,4 %, in cluster 7 – military medicine – 8 % and 6,5 %. There is visualization of keywords, presented in the clusters. Leading scientific schools of co-authorship and affiliated organizations have been identified.

DISCUSSION. There is dynamics of increase in the number of articles on underwater medicine. There are 11 authors, who have published 30 and more articles personally or co-authored in 20 years from 2003 to 2022. 3 lead authors of papers are from China, 2 –Croatia, 2 – Australia. There are surprisingly few lead co-authors from the USA – 1.

CONCLUSION. The conducted studies can increase information support of research on underwater medicine and help scientists determine directions of own scientific work.
