Abstract

Objectives: Nephrology is one the complicated diseases of the human body. This study tries to focus the scholarly communications of Nephrology which were indexed in Science Citation Index Expanded (SCIE) from the Web of Science (WoS) bibliometric database and to observe various elements in terms of yearly growth, author productivity, document, language, institution, geographical, most productive keywords, collaborative index (CI), degree of collaboration (DC) and many more characteristic features during the study period.

Method: The data were collected from the Web of Science Core Collection database by using the keywords as topic ‘Nephrology’ and refined by ‘countries /Territories’ (India) and the time span from 2011 to 2016 indexed in SCI-Expanded. All the records during the period of study have been downloaded completely from the Web of Science online database. The researcher has applied percentage analysis and average score analysis as the basic tools. Apart from the above the specific bibliometric statistical tools such as Collaborative index, Degree of Collaboration, R2 value and Mean, Standard Deviation, C.V and softwares such as HistCite, VOS Viewer have also been applied.

Results:The study revealed that the degree of collaboration ranges from 0.79 to 0.91 and the average degree of collaboration is 0.86. The American Journal of Kidney Diseases was ranked first (global citation score) 1101 (5.5%), The Nephrology Dialysis Transplantation is in the second rank (global citation score) 765 (5.5%). The results showed that the range of collaborative index is from 0.15 to 0.19 between 2011 and 2016. The maximum range of collaborative index is 0.19 in 2011. USA has been placed with 845 research output and the percentage rate is 32.2 and also the global citation score is 5306 and has got the first place based on the record count and followed by Italy.

Conclusion: Scientometric analysis computes to a scientific publication which has highlighted the contribution of institutions, journals, and individual researchers. It can be concluded that the highest (19.5%) number of papers was published in 2014. The USA has maximum number of literature output, and ranked the first. The percentage of multi- authored research output was more than that of single-authored. The pattern of collaborative index was evaluated and the maximum range of collaborative index was 0.19 in the years 2011 respectively. It is concluded that the scholarly communications in Nephrology have been increasing year by year at a substantial rate. This scientometric study will help to identify the relevant journals of subscription for health science librarians to provide effective service to the user community.
