A Comparative Scientometric Analysis of the 100 Most Cited Articles of Acta Neurochirurgica (Wien) and World Neurosurgery.

ABSTRACT BACKGROUND Acta Neurochirurgica, (ANCH) and World Neurosurgery (WN), are two journals of significant importance in the neurosurgical community and have been associated with international federations. Of note is that these journals carry a similar impact factor. The difference is the years they have been active (ANCH starting publications in 1973 and WN in 2010). This allows for a unique opportunity to delve deep into comparative, scientometric parameters, to understand the evolution of neurosurgical research. METHODS A title specific search of the Web of Science database using the keywords ‘ACTA NEUROCHIRURGICA’, ‘Acta’ and ‘Neurochirurgica’; ‘World Neurosurgery’; ‘World’ and ‘Neurosurgery’ was done and arranged according to number of citations. Title of the articles, authors, corresponding authors, country of origin, journal of publication, year of publication, citation count and the journal impact factor were assessed. RESULTS The average citation for ANCH was 170.1 citations, majority being original articles (83/100). The articles of WN, garnered nearly 70.48 citations, averaging 8.3 citations per publication. Most corresponding authors in Acta originated from Germany with Neuro-oncology, followed by Neurotrauma and Vascular as subjects. In contrast the United States of America followed by China were the most common countries of origin for WN with ‘Endoscopy’ and ‘Skull-base’ being the topics achieving high impact. CONCLUSIONS Neurotrauma and consensus guidelines have been shown to have maximal citations for ANCH while Endoscopy and Skull-base lesions garnered the most for WN. Author subspecialisation and increased collaboration across specialities with more articles on refinement of technique and outcome have emerged as recent trends.
