The objective of this paper is to explore approaches to understanding the usability of health information systems at regional and national levels.
Several different methods are discussed in case studies from Denmark, Finland and Canada. They range from small scale qualitative studies involving usability testing of systems to larger scale national level questionnaire studies aimed at assessing the use and usability of health information systems by entire groups of health professionals.
It was found that regional and national usability studies can complement smaller scale usability studies, and that they are needed in order to understand larger trends regarding system usability. Despite adoption of EHRs, many health professionals rate the usability of the systems as low. A range of usability issues have been noted when data is collected on a large scale through use of widely distributed questionnaires and websites designed to monitor user perceptions of usability.
As health information systems are deployed on a widespread basis, studies that examine systems used regionally or nationally are required. In addition, collection of large scale data on the usability of specific IT products is needed in order to complement smaller scale studies of specific systems.
本文的目标是探索在区域和国家层面理解健康信息系统可用性的方法。
在丹麦、芬兰和加拿大的案例研究中讨论了几种不同的方法。这些方法从小规模的定性研究（涉及系统的可用性测试）到大规模的国家级问卷调查研究不等，后者旨在评估全体卫生专业人员对健康信息系统的使用情况和可用性。
研究发现，区域和国家层面的可用性研究可以补充小规模的可用性研究，并且为了理解有关系统可用性的更大趋势，这类研究是必要的。尽管采用了电子健康记录，但许多卫生专业人员对系统可用性的评价较低。当通过广泛分发的问卷和旨在监测用户对可用性感知的网站大规模收集数据时，已经注意到一系列可用性问题。
随着健康信息系统的广泛部署，需要开展针对区域或国家层面使用的系统的研究。此外，为了补充对特定系统的小规模研究，需要收集有关特定信息技术产品可用性的大规模数据。
