Infobuttons to Improve Information Access in Order Entry

D0ESCRIPTION（申请人提供）： 我们假设，当使用一个临床医生订单输入系统（COES），护士和医生遇到特定的信息需求，可以预测的基础上，他们正在审查的信息。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被推迟的速度。这反过来又会提高信息搜索的成功率，从而导致更好的信息订购。我们将研究这个问题，使用程序，所谓的“信息按钮”，使用特定的上下文信息，以预测信息需求和自动检索适当的资源。例如，在COES显示屏中放置在患者数据旁边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为COES研究这种方法了。我们的方法是将我们目前的研究扩展到： .临床医生在三家机构使用商业或当地COES时产生的研究信息需求 .构建信息按钮，以满足已确定的特定需求 .整合从COES到信息按钮的链接 .研究信息按钮改善信息获取的能力 我们的研究将涉及临床医生的直接观察，使用便携式可用性实验室，因为他们使用基于Web的COES在纽约长老会医院，LDS医院和Regenstrief研究所在日常病人护理和“大声思考”他们的信息需求。我们将分析这些活动，以确定在给定的背景下，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。信息按钮将被集成到COES中，我们将研究临床医生对它们的使用，以确定它们在实际患者护理过程中是否可用和有用。

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.
