The evolution of cardiopulmonary resuscitation: Global productivity and publication trends.

BACKGROUND/OBJECTIVE: There is still no comprehensive bibliometric study in the literature on cardiopulmonary resuscitation (CPR), an important topic in emergency medicine, the number of global studies on which is increasing day by day. In this study, it was aimed to analyze the scientific articles on CPR published between 1980 and 2020 by statistical methods and to evaluate the subject holistically.

METHODS

Articles on CPR published between 1980 and 2020 were downloaded from the Web of Science (WoS) database and analyzed using statistical methods. Network visualization maps were used to identify trending topics. Nonlinear regression analysis (exponential model) was used to estimate the number of articles in the coming years. Correlation studies were conducted using the Spearman correlation coefficient.

RESULTS

A total of 21,623 publications were found. Of these publications, 14,818 (68.5%) were articles. The top 3 contributing countries to the literature were the United States (5281, 35.6%), Germany (1458, 9.8%), and the United Kingdom (1152, 7.7%). The 3 most active institutions were the University of Washington (417), University of Pittsburgh (361), and University of Arizona (240). The 3 journals with the most publications were Resuscitation (2822), Critical Care Medicine (522), and the American Journal of Emergency Medicine (421).

CONCLUSION

In this comprehensive study, a summary of 14,818 articles was presented. The trending topics in CPR research in recent years are out-of-hospital cardiac arrest, extracorporeal membrane oxygenation, cardio, simulation, in-hospital cardiac arrest, extracorporeal life support, extracorporeal cardiopulmonary resuscitation, targeted management temperature, and outcome. This article may be a useful resource on CPR global outcomes for clinicians and scientists.
