Acute Chest Syndrome: A Bibliometric Analysis of the Top 100 Most Cited Articles

Acute chest syndrome (ACS) is a major cause of morbidity and mortality in patients with SCD (SCD). The analysis of research productivity and trends in ACS may serve as a valuable guide for investigators, institutions, and funding agencies to plan the future directions of research. The current review aims to evaluate the productivity and trends of publications related to ACS in adults by analyzing the top 100 most cited articles. A bibliometric analysis of the top 100 most cited articles related to ACS in adults was conducted on May 20, 2021. The Scopus database was searched to identify the top-cited articles. The following term was applied: "acute chest syndrome" in the fields of title, abstract, and keyword. The most cited article received a total of 776 citations, while the least cited received a total of 10 citations. Over half of the identified articles received 35 citations or less. The articles originated in 12 different countries; the overwhelming majority of articles originated in the United States (n = 75), with small contributions from developing countries with a high prevalence of sickle cell disease. Blood and American Journal of Hematology published the largest number of articles, with nine articles each. The Author "Vichinsky, E.P." has the largest contribution with a total of 10 articles. The plethora of the highly cited articles were Observational studies, while randomized controlled trials were represented by seven articles. The present study demonstrates that research in ACS may be receiving less attention than it should. Therefore, research empowerment and adequate funding are of paramount importance to improve research productivity and quality. Additionally, more collaborative efforts should be encouraged to reduce the gap between developed and developing countries.
