Electronic health record (EHR) patient portals are designed to provide medical health records to patients. Using an EHR portal is expected to contribute to positive health outcomes and facilitate patient-provider communication.
Our objective was to examine how portal users report using their portals and the factors associated with obtaining health information from the internet. We also examined the desired portal features, factors impacting users' trust in portals, and barriers to using portals.
An internet-based survey study was conducted using Amazon Mechanical Turk. All the participants were adults in the United States who used patient portals. The survey included questions about how the participants used their portals, what factors acted as barriers to using their portals, and how they used and how much they trusted other web-based health information sources as well as their portals. A logistic regression model was used to examine the factors influencing the participants' trust in their portals. Additionally, the desired features and design characteristics were identified to support the design of future portals.
A total of 394 participants completed the survey. Most of the participants were less than 35 years old (212/394, 53.8%), with 36.3% (143/394) aged between 35 and 55 years, and 9.9% (39/394) aged above 55 years. Women accounted for 48.5% (191/394) of the survey participants. More than 78% (307/394) of the participants reported using portals at least monthly. The most common portal features used were viewing lab results, making appointments, and paying bills. Participants reported some barriers to portal use including data security and limited access to the internet. The results of a logistic regression model used to predict the trust in their portals suggest that those comfortable using their portals (odds ratio [OR] 7.97, 95% CI 1.11-57.32) thought that their portals were easy to use (OR 7.4, 95% CI 1.12-48.84), and frequent internet users (OR 43.72, 95% CI 1.83-1046.43) were more likely to trust their portals. Participants reporting that the portals were important in managing their health (OR 28.13, 95% CI 5.31-148.85) and that their portals were a valuable part of their health care (OR 6.75, 95% CI 1.51-30.11) were also more likely to trust their portals.
There are several factors that impact the trust of EHR patient portal users in their portals. Designing easily usable portals and considering these factors may be the most effective approach to improving trust in patient portals. The desired features and usability of portals are critical factors that contribute to users' trust in EHR portals.
电子健康记录（EHR）患者门户旨在为患者提供医疗健康记录。使用EHR门户有望带来积极的健康结果，并促进患者与医疗服务提供者之间的沟通。
我们的目的是研究门户用户如何报告使用他们的门户，以及与从互联网获取健康信息相关的因素。我们还研究了期望的门户功能、影响用户对门户信任的因素以及使用门户的障碍。
使用亚马逊土耳其机器人进行了一项基于互联网的调查研究。所有参与者均为美国使用患者门户的成年人。该调查包括关于参与者如何使用他们的门户、哪些因素成为使用门户的障碍，以及他们如何使用和信任其他基于网络的健康信息源以及他们的门户等问题。使用逻辑回归模型来研究影响参与者对其门户信任的因素。此外，确定了期望的功能和设计特征以支持未来门户的设计。
共有394名参与者完成了调查。大多数参与者年龄小于35岁（212/394，53.8%），36.3%（143/394）年龄在35至55岁之间，9.9%（39/394）年龄在55岁以上。女性占调查参与者的48.5%（191/394）。超过78%（307/394）的参与者报告至少每月使用一次门户。最常使用的门户功能是查看实验室结果、预约和支付账单。参与者报告了一些使用门户的障碍，包括数据安全和互联网接入受限。用于预测对其门户信任的逻辑回归模型结果表明，那些对使用门户感到舒适的人（优势比[OR]7.97，95%置信区间1.11 - 57.32）认为他们的门户易于使用（OR 7.4，95%置信区间1.12 - 48.84），并且经常使用互联网的用户（OR 43.72，95%置信区间1.83 - 1046.43）更有可能信任他们的门户。报告门户在管理其健康方面很重要的参与者（OR 28.13，95%置信区间5.31 - 148.85）以及认为他们的门户是其医疗保健重要组成部分的参与者（OR 6.75，95%置信区间1.51 - 30.11）也更有可能信任他们的门户。
有几个因素会影响EHR患者门户用户对其门户的信任。设计易于使用的门户并考虑这些因素可能是提高对患者门户信任的最有效方法。门户的期望功能和可用性是有助于用户信任EHR门户的关键因素。
