Ideally, searches for published articles to solve clinical problems should lead to the best evidence on a given topic quickly and at reasonable expense. This goal can be achieved with modern information skills, sources, and services. In this article, we describe and compare various means, from textbooks to computers, that provide access to information of potential value in addressing clinical problems as they arise. Using the problem of understanding and controlling the risk for the acquired immunodeficiency syndrome among personnel of a community hospital, we examined the following sources for their utility in locating journal literature: general and specialty medical texts, personal reprint collections, expert clinicians, recent journal issues, library textbook collections, the Index Medicus "Bibliography of Reviews" and subject index, and MEDLINE computer searching. For this problem, Index Medicus and MEDLINE were the best sources of up-to-date articles, but MEDLINE was three times as fast.
理想情况下，为解决临床问题而检索已发表文章应能迅速且以合理成本获取关于特定主题的最佳证据。借助现代信息技能、资源和服务，这一目标是可以实现的。在本文中，我们描述并比较了从教科书到计算机等各种获取潜在有价值信息以应对临床问题的途径。以社区医院工作人员中理解和控制获得性免疫缺陷综合征风险这一问题为例，我们考察了以下资源在查找期刊文献方面的效用：普通医学和专科医学教科书、个人重印文集、专家临床医生、近期期刊、图书馆教科书馆藏、《医学索引》“综述书目”和主题索引，以及医学联机数据库检索。对于这个问题，《医学索引》和医学联机数据库是获取最新文章的最佳资源，但医学联机数据库的检索速度快三倍。
