Emergency medicine publication habits and impact between different world regions Emergency medicine publication impact and habits for SciVal publication regions
Introduction
Region
Research impact from different world regions likely depends on the development stage of emergency medicine in that region, research resource availability and access to funding. The aim of this study was to provide an overview of emergency medicine publication impact and habits for six publication regions

Methods The author made use of SciVal (Elsevier Research Intelligence, New York, NY) for the analysis. SciVal is an online data analytics programme that allows access to research performance of authors, groups, journals, research fields, research institutions and countries. It allows benchmarking in various combinations of variables for detailed analysis. Variables analysed for this study included publication counts, citations per publication, field-weighted citation impact, collaboration rate and publication rate in top 10% most cited publications, and top journals for the regions: Africa, Europe, Asia-pacific, Middle-East, North and South America. The top five journals and countries (by publication count) for each region is also provided along with the Source Normalized Impact per Paper and field-weighted citation impact (FWCI) respectively. Eligible publications in the Scopus database between 2010 and 2015 were included.

What does these findings mean…
South American authors should focus on maintaining quality and increasing volume, Middle Eastern authors should focus on maintaining volume and increasing quality and African authors should focus on increasing both volume and quality. Discussion Regional publication appears common. Subject relevance and non-English language publications likely play a role in regional publication. South America has a high non-regional publication count, international collaboration rate and citation impact suggesting use of collaboration to bolster quality. This is not seen with Africa, which has a similarly high international collaboration rate but low citation impact.
The Middle-East fails on both accounts despite a reasonable publication count. This finding suggests underdeveloped emergency medicine research systems in these two regions. Stevan R Bruijns (
