Analysis of Metrics for the Usability Evaluation of EHR Management Systems

Electronic health records are replacing conventional paper-based health records. For a doctor it is a working instrument, which can significantly reduce the time spent on paper work. Patients can benefit from accessing the electronic health records even though they usually do not have a medical background. Therefore, when specifying a graphical user interface (GUI) it is necessary to take into account the requirements of the different users: e.g. the functionality for the doctors and the presentation of data in an understandable manner for the patients. The study aims to review and analyze metrics used to evaluate the usability of user interfaces in health information systems. The scope of the search included the analysis of existing usability evaluating metrics that are applied both in healthcare and other domains, where the standard of storage and presentation of information are applied. We identified a set of metrics and evaluation methods that provide holistic evaluation facilities for graphical user interfaces.
