Abstract

Abstract

Background
Scientometric analyses characterize the output of research publications using quantitative methods. While it has been reported that the number of publications in anesthesiology has been increasing for years, the global research activity in pediatric anesthesiology and its landscape is largely unknown.
Aims
To examine the activity, developmental dynamics, and collaboration landscape of research publications in pediatric anesthesiology over the past two decades.
Methods
PubMed and WebOfScience were searched for pediatric anesthesiology publications published between 2001 and 2020. The identified publications were exported into a database, matched, curated, and then assigned to one or more countries according to their affiliation field(s). The primary outcome was the publication activity and its growth rate. Secondary outcomes included the geographical distribution, the evolution of international collaborations (as indicated by articles affiliated with more than one country), and the main sources.
Results
Thirty-four thousand, three hundred and forty-three pediatric anesthesiology publications were retrieved. The compound annual growth rate over the study period was +7.6%. The highest annual growth rate was +20.6% from 2019 to 2020. Corresponding authors were most often affiliated with USA (32.5%), Germany (5.5%), and China (5.5%). China (+22.9%), Iran (+21.7%), and India (+16.1%) had the highest compound annual growth rates. 6001 (17.5%) articles involved international collaboration, with a compound annual growth rate of +13.1%. The most frequent collaboration was between USA and Canada (716 articles together). The most prominent source was Pediatric Anesthesia (10.0%).
Conclusions
Publication activity in pediatric anesthesiology has increased from 2001 to 2020 and has become more geographically diverse. With the volume of international collaborations even outpacing this growth, it is hoped that this will gradually lead to a larger evidence base in pediatric anesthesia.
