Women authorship in pain research: A bibliometric analysis from 2002 to 2021

Abstract

AbstractObjectivesThere is a lack of data on the distribution of women first and senior authorships in pain journals. Using articles published in top North American pain journals over the past two decades, we sought to describe the prevalence and changes in women representation among first and last authors.MethodsWe retrieved all published research articles in four pain journals (Regional Anesthesia and Pain Medicine, Clinical Journal of Pain, Pain and The Journal of Pain) from 2002 to 2021 using the easyPubMed package. Subsequently, the ‘gender’ package in R was used to determine authors' gender by first names. Trends in gender authorship change over time were assessed.ResultsThe final cohort consisted of 20,981 authors (from an initial total of 11,842 publications and 23,684 authors retrieved). Women authors were more often first compared to senior authors (46.7% vs. 30.5%). The proportion of women first authors (46.2% in 2002 vs. 48.4% in 2021) and women senior authors (22.4% in 2002 vs. 36.3% in 2021) increased over the course of the study period (all p‐value <0.001). The Clinical Journal of Pain having the highest percentage of women authors and Regional Anesthesia and Pain Medicine had the lowest percentage of women authors.DiscussionOur data demonstrated increasing women authorship in pain journals in the past 20 years, largely driven by an increase in first authorships. There still remains a large gap between first and senior authorship, indicative of disparity in the role that women play in research.
