Bibliometric Analysis of Global Sickle Cell Disease Research From 1997 – 2017

Abstract

Background: Sickle cell disease (SCD) is an autosomal recessive genetic disease caused by single point mutation in the β-globin chain of the hemoglobin. It has been recognized by World Health Organization as a public health priority since 2006. Methods: Scopus database was used in this study with the search descriptors: “sickle cell” and “sickle cell disease”. We applied common bibliometric indicators to evaluate the trend in scientific literature in sickle cell disease research. Results: We retrieved a total of 19,921 scientific literatures in the repertoire from 1997 to 2017. Price law was fulfilled in the trend of production of scientific literature in SCD as the growth of scientific literature was more exponential (r = 0.959) than linear (r = 0.9449). We observed a duplication time of 4.55 years. The Bradford core was made up of 69 journals with Blood at the top, publishing the most number of articles. The most productive institutions were mostly United States agencies and hospitals. United States was the most productive country. National Institute of Health was the most productive institution and also had the highest number of citation. Vichinsky E was the most productive author while the most cited article was published by Circulation. Conclusion: The growth of scientific literature in SCD was found to be high. However, the exponential growth trend shows a “yet-to-be-explored” area of research. This study will be useful for physicians, researchers, research funders, policy cum decision makers.

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

“…In agreement with our result, Okoroiwu et al identified "Vichinsky, E.P." as the most contributing author in SCD research; however, Musaa et al identified "Serjeant GR" as the most productive author [6,7]. Highlighting the most contributing authors in ACS may help investigators around the world plan future directions and collaborations.…”

“…The largest number of publications were published in "Blood" and "American Journal of Hematology," with nine articles each. In concordance, previous bibliometric analyses identified these two journals as the most productive journals in SCD [6,7]. Hence, these journals could be recommended for investigators interested in this field.…”

“…A total of 11,917 documents were retrieved, with an average of 27.34 citations for each document [6]. Similarly, Okoroiwu et al investigated the productivity and trends of SCD research published over two decades (1997-2017) using the Scopus database [7]. A total of 19,921 documents were retrieved [7].…”

To our knowledge, analyses concerning specific complications of SCD, including ACS, have not been conducted before.…”
