DESCRIPTION (provided by the applicant): Goals and Objectives: The main goal of this study is to evaluate whether use of an electronic patient portal can reduce health services utilization and improve quality of care in a population of rural, chronically ill patients. The first aim of this study is to develop a typology for describing how patients use the portal. The second aim is to describe the patient characteristics associated with different patterns of portal use. The third aim is to evaluate the effect of portal use on patient utilization and quality of care. This study is highly relevant to AHRQ's mission to increase the development, diffusion, and adoption of health information technology (HIT) to improve the quality of health care. Background: Patient portals are a new type of HIT that allow patients to securely access both their personal medical information and their healthcare provider from any Internet-connected computer. Portals may empower patients to become more involved in, and improve the outcomes of, their care. Few studies of portals have been conducted. Methods/Data Sources: This study is a secondary analysis of data being collected by Geisinger Health System (GHS), an integrated delivery system serving rural Pennsylvania, as part of GHS's ongoing study of a portal-based intervention to improve the care of chronically ill patients. Data from approximately 2,000 users in the intervention arm and 2,000 users in the control arm of the GHS study will be available for comparison with 2,000 non-users of the portal. Comprehensive patient data and encounter information will be available from GHS's electronic health record. A telephone survey previously conducted by GHS will provide detailed information on additional patient-level variables, including patient activation and Internet use, for a subset of 200 users from each arm of the GHS study. The first aim will use log-file analysis and factor analysis models to develop a typology of portal use. The second aim will use regression models to describe the association between portal usage patterns and patient characteristics. The third aim will use regression models to describe the association between portal use and utilization and clinical outcomes. Significance: This study will provide some of the first evidence of the potential for patient-centered HIT to improve chronic disease care, a significant public health issue requiring new approaches and tools. In addition, this study addresses a rural and a chronically ill population, both of which AHRQ has identified as priority populations.

描述（由申请人提供）： 目标和目的：本研究的主要目标是评估电子患者门户的使用是否可以减少农村慢性病患者群体的医疗服务利用率并提高护理质量。本研究的首要目的是开发一种类型学来描述患者如何使用门户。第二个目的是描述与不同门户使用模式相关的患者特征。第三个目标是评估门户网站的使用对患者利用率和护理质量的影响。这项研究与 AHRQ 的使命高度相关，即促进健康信息技术 (HIT) 的开发、传播和采用，以提高医疗保健质量。背景：患者门户是一种新型 HIT，允许患者从任何连接互联网的计算机安全地访问其个人医疗信息和医疗保健提供者。门户网站可以让患者更多地参与护理并改善护理结果。对门户网站的研究很少。方法/数据来源：本研究是对 Geisinger Health System (GHS) 收集的数据进行的二次分析，Geisinger Health System (GHS) 是一个为宾夕法尼亚州农村地区提供服务的综合服务系统，作为 GHS 正在进行的基于门户的干预措施研究的一部分，以改善慢性病患者的护理患者。 GHS 研究干预组中约 2,000 名用户和对照组中约 2,000 名用户的数据将可与门户网站的 2,000 名非用户进行比较。 GHS 的电子健康记录将提供全面的患者数据和遭遇信息。 GHS 之前进行的电话调查将为 GHS 研究各组的 200 名用户提供有关其他患者层面变量的详细信息，包括患者激活和互联网使用情况。第一个目标将使用日志文件分析和因子分析模型来开发门户使用的类型。第二个目标将使用回归模型来描述门户使用模式与患者特征之间的关联。第三个目标将使用回归模型来描述门户使用和利用与临床结果之间的关联。意义：这项研究将为以患者为中心的 HIT 改善慢性病护理的潜力提供一些初步证据，这是一个需要新方法和工具的重大公共卫生问题。此外，这项研究还针对农村人口和慢性病人口，AHRQ 已将这两者确定为优先人口。
