Infobuttons to Improve Information Access in Order Entry

描述(由申请人提供)： 我们假设，当使用临床医生订单录入系统(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审查的信息进行预测。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速度。反过来，这应该会提高信息搜索的成功率，导致更知情的排序。我们将使用被称为“信息按钮”的程序来研究这个问题，这些程序使用特定于上下文的信息来预测信息需求，并从适当的资源中自动检索。例如，在COES显示中，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COE研究这种方法了。我们的方法将是将我们目前的研究扩展到： 。研究临床医生在三个机构使用商业或本地CoE时出现的信息需求 。构建信息按钮，以满足已确定的特定需求 。集成从COE到信息按钮的链接 。研究信息按钮改善信息获取的能力 我们的研究将包括使用便携式可用性实验室直接观察临床医生，因为他们在常规患者护理期间使用纽约长老会医院、LDS医院和Regenstrief Institute的基于Web的CoE，并“大声思考”他们的信息需求。我们将分析这些活动，以确定在给定环境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COE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.
