Social Attention through Altmetric Score Analysis for End-tidal Carbon Dioxide and Capnography

Abstract

Objectives: Altmetric analyses highlight key publications in terms of social media. Throughout recent years, socialmedia platforms have been playing important roles in the promotion, spread and display of medical literature. The aimof the present study was to determine the most influential literature on end-tidal carbon dioxide or ETCO2 and capnographyin the last decade and to evaluate the changing trends in altmetric attention scores over time.Methods: ‘’End-tidal CO2’’ or ‘’Capnography’’ as a search term was entered into Thomson Reuter’s Web of Science databaseto identify all articles in the field. The 50 most-cited articles were analysed by topic trends, sources, authors,publication years, and altmetric attention scores.Results: 2822 articles were screened from Web of Science. Among these, the 50 most cited articles were selected. Inthe analyzed articles the median (range) citation and altmetric score values were 52 (37-424) and 6 (1-212) respectively.The most cited article in the top 50 list was “Major complications of airway management in the UK: results of the FourthNational Audit Project of the Royal College of Anaesthetists and the Difficult Airway Society. Part 2: intensive careand emergency departments” published by Cook TM et al. in 2011. The highest number of articles were published injournals Journal of Applied Physiology (n=5) and Resuscitation (n=5). The altmetric scores were rather low and did notshowed a linear association with the citation counts of top 50 articles on ETCO2 and capnography.Conclusion: Bibliometric based altmetric analysis provide important but different perspectives regarding article impact.Future studies with the use of ETCO2 with capnography in wider indications being more recognized in socialmedia would contribute to the current knowledge.
