Infobuttons to Improve Information Access in Order Entry

D0说明（由申请人提供）： 我们假设，在使用临床医生医嘱输入系统 (COES) 时，护士和医生会遇到特定的信息需求，这些需求可以根据他们正在查看的信息进行预测。通过自动提供旨在解决这些需求的在线资源的链接，我们可以降低信息搜索的延迟率。反过来，这应该会提高信息搜索的成功率，从而实现更明智的订购。我们将使用称为“信息按钮”的程序来研究这个问题，该程序使用特定于上下文的信息来预测信息需求并自动从适当的资源中检索。例如，COES 显示中患者数据旁边放置的信息按钮可以使用患者数据本身来促进信息检索。我们认为现在是时候在多个机构研究 COES 的这种方法了。我们的方法是将我们当前的研究扩展到： 。当临床医生在三个机构使用商业或当地 COES 时出现的研究信息需求 。构建满足已确定的特定需求的信息按钮 。集成从 COES 到信息按钮的链接 。研究信息按钮改善信息访问的能力 我们的研究将涉及使用便携式可用性实验室对临床医生进行直接观察，因为他们在纽约长老会医院、LDS 医院和 Regenstrief 研究所在常规患者护理期间使用基于网络的 COES，并“大声思考”他们的信息需求。我们将分析这些活动，以确定在给定背景下最有可能出现的信息需求。然后，我们将构建独立于机构的信息按钮，以自动检索与特定需求相关的特定信息。信息按钮将集成到 COES 中，我们将研究临床医生的使用情况，以确定它们在实际患者护理过程中是否可用。

D0ESCRIPTION (provided by applicant): We hypothesize that when using a clinician order entry system (COES), nurses and physicians encounter specific information needs that can be predicted based on the information they are reviewing. By automatically providing links to on-line resources designed to resolve those needs, we can decrease the rate at which information seeking is deferred. This should, in turn, increase the rate at which information seeking is successful, leading to better-informed ordering. We will study this problem using programs, called "infobuttons" that use context-specific information to anticipate information needs and automate retrieval from appropriate resources. For example, an infobutton placed next to patient data in a COES display can use the patient data itself to facilitate information retrieval. We believe it is time to study this approach for COES, at multiple institutions. Our approach will be to extend our current research to: . Study information needs that arise when clinicians use commercial or local COES's at three institutions . Build infobuttons that address the specific needs that are identified . Integrate links from the COES's to the infobuttons . Study the ability of the infobuttons to improve access to information Our study will involve the direct observation of clinicians, using a portable usability laboratory, as they use Web-based COES's at New York Presbyterian Hospital, LDS Hospital and Regenstrief Institute during routine patient care and "think aloud" about their information needs. We will analyze these activities to determine, for a given context, the information needs most likely to arise. We will then construct institution-independent infobuttons to automate the retrieval of specific information relevant to specific needs. The infobuttons will be integrated into the COES and we will study their use by clinicians to determine if they are usable and useful in the process of actual patient care.
