TITLE: Analysis of research output parameters: Density equalizing mapping 
and citation trend analysis (Article, English)

ABSTRACT:  Background: Burden of disease studies indicate major
socio-economic burdens since many years. They should be used for the 
allocation of funding. However, imbalances are present in funding policies 
and therefore benchmarking becomes increasingly important in health 
services research.  

Methods: The present study assessed benchmarking approaches. Using large 
data base analyses, research was analyzed for different health research 
output parameters. The fields of cardiovascular and respiratory medicine 
served as models to assess irregular patterns of health research. For 
visualization, density equalizing mapping procedures were used.  

Results: Specific areas of major research activity were identified for 
European countries and large differences were found. Spatial distribution 
of published items for cardiac and cardiovascular systems differed in 
comparison to the distribution for the respiratory system. In general, 
large countries dominated the overall number of published items. When 
qualitative measures such as citation analysis were assessed, differing 
results were achieved. In this category, mostly Scandinavian countries 

Conclusion: The present approach of comparative output benchmarking can be 
used to assess institutional operating figures at the national and 
international level and to analyze imbalances in health and research
