OBJECTIVE
To examine and compare the research productivity of the European Union, the four "candidate" countries (those currently waiting to join the EU), and the United States in several fields of biomedical sciences.
DESIGN
A retrospective observational study-bibliometric analysis.
DATA SOURCES
Manuscripts published by authors from each country separately and from each group of countries for the period 1994 to 2004 and included in the Essential Science Indicators database of the Institute of Scientific Information.
MAIN OUTCOME MEASURES
Number of published articles and number of citations, adjusted for gross domestic product and population size.
RESULTS
1,485,749 articles were published by authors from the EU compared with 1,356,805 from the US. The research productivity of the first 15 countries to join the EU, adjusted for population, was lower (76%) than that of the US-and even lower (66%) when the 10 newest EU countries were included in the analysis.
CONCLUSION
The newest EU members and the EU candidate countries need further help and resources to increase their productivity, thereby improving the productivity of the EU as a whole.
目的
考察并比较欧盟、四个“候选”国家（即目前正等待加入欧盟的国家）以及美国在生物医学科学若干领域的研究产出。
设计
一项回顾性观察研究——文献计量分析。
数据来源
1994年至2004年期间，由各国作者分别以及各国作者群体发表并被收录于科学信息研究所基本科学指标数据库的手稿。
主要观察指标
发表文章数量及被引次数，并根据国内生产总值和人口规模进行调整。
结果
欧盟作者发表了1,485,749篇文章，而美国作者发表了1,356,805篇。加入欧盟的前15个国家经人口调整后的研究产出低于美国（76%）——若将10个最新加入欧盟的国家纳入分析，这一比例甚至更低（66%）。
结论
欧盟最新成员国以及欧盟候选国家需要更多帮助和资源来提高其产出，从而提升欧盟整体的产出。
