目的：信息按钮是嵌入在其他应用程序中的基于消息的内容搜索和检索功能，可动态返回与手头临床任务相关的信息。本研究的目的是确定是否infobuttons有效地回答供应商的问题，药物或影响病人的护理decision.Design：作者实施和评估的药物infobutton应用程序称为KnowledgeLink。18家门诊诊所的医疗保健提供者被随机分配到两个版本的KnowledgeLink中的一个，一个链接到Micromedex（Thomson Micromedex，格林伍德村，Co）的信息，另一个链接到SkolarMD（Wolters Kluwer Health，Palo Alto，CA）的材料。测量：收集有关使用频率和用户，患者和药物的人口统计学数据。使用者定期接受简短的问卷调查，然后在一年结束时进行更广泛的调查。结果：在第一年，359名用户使用KnowledgeLink 7,972次，查找了4,961名患者的1,723种药物信息。临床医生平均每月使用KnowledgeLink两次，平均1.2%的患者使用KnowledgeLink。KnowledgeLink被各种各样的医务人员使用，而不仅仅是医生和护士。使用频率和询问的问题因用户角色（初级保健医生、专科医生、执业护士）而异。虽然KnowledgeLink会话的中位数很短（21秒），但KnowledgeLink在84%的时间内回答了用户的查询，并在15%的时间内改变了患者的护理决策。用户评价KnowledgeLink有利的多个尺度，建议扩展KnowledgeLink到其他内容domains，并建议加强界面，使查询和选择的目标resource.Conclusion：一个信息按钮可以满足信息，需要有关药物。尽管KnowledgeLink的使用频率不高，而且只用于简短的会议，但它受到了积极的欢迎，回答了大多数用户的问题，并对医疗决策产生了重大影响。下一步将是扩大KnowledgeLink涵盖的领域，以便更具体地根据用户类型定制结果，在查询没有立即得到回答时提供选项，并在其他电子临床应用程序中实施KnowledgeLink。
Objective: Infobuttons are message-based content search and retrieval functions embedded within other applications that dynamically return information relevant to the clinical task at hand. The objective of this study was to determine whether infobuttons effectively answer providers' questions about medications or affect patient care decisions.Design: The authors implemented and evaluated a medication infobutton application called KnowledgeLink. Health care providers at 18 outpatient clinics were randomized to one of two versions of KnowledgeLink, one that linked to information from Micromedex (Thomson Micromedex, Greenwood Village, Co) and the other to material from SkolarMD (Wolters Kluwer Health, Palo Alto, CA).Measurements: Data were collected about the frequency of use and demographics of users, patients, and drugs that were queried. Users were periodically surveyed with short questionnaires and then with a more extensive survey at the end of one year.Results: During the first year, KnowledgeLink was used 7,972 times by 359 users to look up information about 1,723 medications for 4,961 patients. Clinicians used KnowledgeLink twice a month on average, and during an average of 1.2% of patient encounters. KnowledgeLink was used by a wide variety of medical staff, not just physicians and nurse practitioners. The frequency of usage and the questions asked varied with user role (primary care physician, specialist physician, nurse practitioner). Although the median KnowledgeLink session was brief (21 seconds), KnowledgeLink answered users' queries 84% of the time, and altered patient care decisions 15% of the time. Users rated KnowledgeLink favorably on multiple scales, recommended extending KnowledgeLink to other content domains, and suggested enhancing the interface to allow refinement of the query and selection of the target resource.Conclusion: An infobutton can satisfy information, needs about medications. Although used infrequently and for brief sessions, KnowledgeLink was positively received, answered most users' questions, and had a significant impact on medical decision making. The next steps would be to broaden the domains that KnowledgeLink covers to more specifically tailor results to the user type, to provide options when queries are not immediately answered, and to implement KnowledgeLink within other electronic clinical applications.
