MOBILE TIMELINE - Mobile Charting System that Provides a Graphical Summary of a Patient’s Medical Record

Abstract

In this paper, we introduce a novel medical information system that works on smartphones. This system provides chronological graphs of a patient's medications and medical examinations over an extended period of years as graphical summaries of the patient's medical history so that physicians can gain a clear understanding of the patient's status and develop treatment plans easily. In our system, we implemented the original algorithm that reduces the amount of medical data by merging adjacent data hierarchically when the time span for displaying the data is changed. By implementing this algorithm, the system proposed here was shown to be about 30 times faster than the system with a conventional method. Also, we evaluated our system through the experiment in medicine using real medical records. The results indicate that physicians would benefit significantly by using our system especially in situations where they cannot use another medical information system through their PC, such as the patient's bedside.
