Attempts to link clinical information systems to on-line information resources date back over a decade. The World Wide Web presents new opportunities to create such links, which we refer to as "infobuttons". This capability is partly due to the ease with which a link (called a Uniform Resource Locator, or URL) in one Web-based system can take users to another Web-based system, and partly due to the proliferation of high-quality Web-based resources. Typically, contextual information from the clinical system (such as patient data) is passed to a search engine that is evoked and, in turn, presents search results to the user. Impediments to infobutton development include customized programming to pass context information to the information resource, lack of standards for types and values of context information, variability of search engine interfaces, and a lack of understanding of clinicians' information needs. We are addressing these limitations with an Infobutton Manager (IM) that provides a standardized interface for matching user contexts to information resources.
将临床信息系统与在线信息资源相连接的尝试可以追溯到十多年前。万维网为创建此类连接带来了新机遇，我们将其称为“信息按钮”。这种能力部分归功于基于网络的一个系统中的链接（称为统一资源定位符或URL）能轻松地将用户导向另一个基于网络的系统，部分归功于高质量的基于网络的资源的激增。通常，来自临床系统的上下文信息（如患者数据）会传递给被唤起的搜索引擎，进而向用户呈现搜索结果。信息按钮开发的障碍包括将上下文信息传递给信息资源的定制编程、上下文信息的类型和值缺乏标准、搜索引擎界面的多样性以及对临床医生信息需求的理解不足。我们正在通过信息按钮管理器（IM）来解决这些限制，该管理器提供了一个标准化接口，用于将用户上下文与信息资源进行匹配。
