Publishing trends in Journal of Paediatric Surgery, Pediatric Surgery International and European Journal of Pediatric Surgery over the past three decades.

The aim of this study was an analysis of the changing publication trends over the last three decades in the Journal of Pediatric Surgery (JPS), Pediatric Surgery International (PSI) and European Journal of Pediatric Surgery (EJPS) by studying the bibliometric variables, authorship, collaboration, and citation trends. A previously applied methodology using intermittent years was applied to review the archives of JPS, PSI and EJPS over the last 30 years. Citation data were collected from the Web of Science database. Statistical analysis was performed using SAS 9.4 software. A total of 1917 articles originating from 63 countries met the inclusion criteria. The number of articles published every year increased significantly in the last three decades from 336 in 1987 to 626 in 2017 (P < 0.0001). Multinational papers made up 5% of the total, of which 58% involved more than one continent. A majority of papers (75%) were single institution papers, there was strong evidence of an increase in multi-institution publications over time. There was a statistically significant increase in the number of female first and corresponding author. The publishing landscape of paediatric surgery has evolved to be more inclusive with increased collaboration, female authors and mentors and more publications from developing nations.
