Research on delirium: A scientometric assessment of publications from India during 2001 to 2020

Aim: To analyze the publication growth, international collaboration, funding support, citation impact, and distribution of publications on delirium with one of the authors from India, indexed in Scopus database, published during 2001–2020. Methodology: The Scopus database (http://www.scopus.com) was searched for publications on delirium during 2001–2020 with one of the authors from India. The publications were identified and retrieved. Results: The initial search, which involved locating the global publication output, yielded 22,929 records. When the search was limited to research originating from India, it yielded 478 Indian records. Researchers from India contributed to 2.08% of the world's delirium research, and overall, the research output from India, ranked twelfth in the world. Of the research originating from India, only 12.97% of publications involved international collaboration. The number of publications on delirium with one of the authors from India increased from 1 in the year 2001 to 47 in the year 2020, accounting for 33.61% annual average growth rate, higher than 9.5% of publication growth rate on the topic for the worldwide publications. The 10-year cumulative publications increased from 84 during 2001–2010 to 394 during 2011–2020, registering 369% absolute growth, which was much higher than 107.52% of the world publications. Conclusion: To conclude, this study suggests that only 2% of the world's delirium research emerges from India and overall based on this research output, India stands at the 12th position in delirium research. However, over the last few years, the research on delirium from India has increased.
