Towards the development of an interface model for information visualization in multiple electronic health records

Electronic Health Records (EHR) presented through visual analytic systems could be easily interpreted by physicians for better understanding of a patient's medical details. However, there are still a lot of issues with the existing visual analytical applications in terms of the physicians to correctly infer those medical data. The existing applications were found to be more focusing on the colour schemes and differential data representation in the same space but lesser emphasis was given on defragmentation of information to discrete level and, no provision of detailed overview of patient history in the past time frames. These limitations motivate us to formulate a conceptual interface model that could assist designers in better understanding the physicians' needs. As multiple EHR data is usually obtained from various resources, the best approach for such a formulation would be a combination of events based patient history to a sequence based time line in a similar group. This will help in generating the visual information on different data sets in a time frame of particular length from various data resources onto multiple interfaces. The proposed model, having multiple interfaces features within the same interface, is envisaged to be detailed enough in terms of the data presented yet easy to be understood by the physicians.
