摘要
The high data density on electronic medical record screens is touted as a major usability issue. However, it may not be a problem if the data is relevant and well-organized. Our objective was to test this assumption using a comprehensive set of measures that assess the three pillars of usability: efficiency (both physical and cognitive), effectiveness, and satisfaction. Physicians were asked to go through a series of tasks using two versions of the same electronic medical record: one where all the display items were separated into tabs (the original display), and one where important display items were grouped logically in one tab (the redesigned display). Results supported the hypothesis that combining relevant data in organized fashion into a smaller location would improve usability. The findings highlight the role of good display organization to mitigate the effects of high data density, as well as the importance of assessing cognitive load as part of usability studies.
