International publishing in anaesthesia - how do different countries contribute?

Area of Science:

• Anaesthesiology research
• Biomedical publication analysis

Background:

• International distribution of biomedical research is of significant interest.
• Assessing the global research landscape in anaesthesiology provides insights into scientific productivity and trends.

Purpose of the Study:

• To evaluate the recent evolution of worldwide research distribution in anaesthesiology.
• To identify factors influencing changes in the interpretation of absolute research results.

Main Methods:

• Conducted a Medline search for articles from 10 key anaesthesia journals (1997-2001).
• Analyzed publication data, standardizing by journal impact factor and population size.
• Examined annual publication trends and country-specific distributions.

Main Results:

• A total of 9,724 publications originated from 65 countries.
• The USA led in absolute publications (24.4%), but its contribution decreased from 28.6% to 21.8%.
• Germany's contribution increased from 5.1% to 9.4%; Finland, Sweden, and Denmark led in publications per capita.

Conclusions:

• Anaesthesiology publication geography requires analysis beyond absolute numbers.
• North European countries exhibit the highest research output relative to population size.
• Germany demonstrated the most significant percentage increase in anaesthesiology research contributions during the study period.
