Biomedical informatics is a young, highly interdisciplinary field that is evolving quickly. It is important to know which published topics in generalist biomedical informatics journals elicit the most interest from the scientific community, and whether this interest changes over time, so that journals can better serve their readers. It is also important to understand whether free access to biomedical informatics articles impacts their citation rates in a significant way, so authors can make informed decisions about unlock fees, and journal owners and publishers understand the implications of open access. The topics and JAMIA articles from years 2009 and 2010 that have been most cited according to the Web of Science are described. To better understand the effects of free access in article dissemination, the number of citations per month after publication for articles published in 2009 versus 2010 was compared, since there was a significant change in free access to JAMIA articles between those years. Results suggest that there is a positive association between free access and citation rate for JAMIA articles.
生物医学信息学是一个年轻的、高度跨学科的领域，发展迅速。了解一般生物医学信息学期刊中哪些已发表的主题最能引起科学界的兴趣，以及这种兴趣是否随时间而变化，这一点很重要，这样期刊才能更好地为读者服务。了解生物医学信息学文章的免费获取是否会对其引文率产生重大影响也很重要，这样作者就可以在解锁费用方面做出明智的决策，而期刊所有者和出版商也可以理解开放获取的影响。根据 Web of Science，描述了 2009 年和 2010 年被引用最多的主题和 JAMIA 文章。为了更好地了解免费获取对文章传播的影响，比较了 2009 年和 2010 年发表的文章在发表后每月的引文数量，因为这两年 JAMIA 文章的免费获取方式发生了重大变化。结果表明，JAMIA 文章的免费获取与引文率之间存在正相关关系。
