Bibliometric methods, based on the count of articles published in scientific journals, are increasingly used to evaluate scientific productivity. Bibliometric studies may identify factors that promote or inhibit research performance. We set out to analyze dermatologic research activity in Sweden, Denmark, Finland, and Norway using bibliometric methods.
We performed repetitive searches on Medline, using the PubMed interface, for the period 1989-2008. Dermatologic articles were defined as all articles in dermatologic journals plus articles in nondermatologic journals in which the address of first author included an institution of dermatology. Articles were allocated to the country of first author's address.
The number of dermatologic articles from Sweden, Denmark, Finland, and Norway was 1896 (214 per million inhabitants), 1502 (281), 1017 (196), and 249 (55), respectively. Dermatologic articles represented 1.4%, 2.3%, 1.6%, and 0.6% of each country's total number of Medline articles in English over the same period. Similar patterns were found in relation to gross domestic product, number of dermatologists, and number of medical schools. After 2000, the yearly number of dermatologic articles from Denmark increased and that from Finland decreased, whereas the numbers from Sweden and Norway remained relatively stable.
Despite similarities in social and economic conditions in Sweden, Denmark, Finland, and Norway, there are great differences in dermatologic research activity in the four countries, with Denmark performing best and Norway poorest. Historical and cultural factors may partly explain these differences.
基于科学期刊发表文章数量的计量方法，越来越多地被用于评估科学生产力。计量研究可以确定促进或抑制研究绩效的因素。我们采用计量方法，旨在分析瑞典、丹麦、芬兰和挪威的皮肤科研究活动。
我们在 1989 年至 2008 年期间，使用 PubMed 接口，在 Medline 上进行了多次重复搜索。皮肤科文章被定义为皮肤科期刊中的所有文章，以及第一作者地址中包含皮肤科机构的非皮肤科期刊中的文章。文章被分配到第一作者地址所在的国家。
瑞典、丹麦、芬兰和挪威的皮肤科文章数量分别为 1896（每百万居民 214 篇）、1502（281 篇）、1017（196 篇）和 249（55 篇）。皮肤科文章占同期各国英文 Medline 文章总数的 1.4%、2.3%、1.6%和 0.6%。在国内生产总值、皮肤科医生人数和医学院数量方面也存在类似的模式。2000 年后，丹麦的皮肤科文章数量逐年增加，芬兰则逐年减少，而瑞典和挪威的数量则相对稳定。
尽管瑞典、丹麦、芬兰和挪威在社会和经济条件方面存在相似之处，但这四个国家的皮肤科研究活动存在很大差异，丹麦表现最好，挪威最差。历史和文化因素可能部分解释了这些差异。
