Japan System Techniques Co., Ltd. (JAST) has started providing at no cost a medical data dashboard that uses Tableau,a data visualization tool for progress with the digital transformation (DX) of the health care sector. The dashboard uses
the JAST’s anonymous health insurance invoice data for about 8 million people (see note 1) and the REZULT medical
big data platform, which uses medical examination data as the source.
Three categories of data are accessible using this dashboard: basic data, data using ICD10 (see note 2), and COVID-19
data. Visualization of each category is possible for individual prefectures of Japan. In addition, percentages based on
gender and age as well as the number of patients in a month can be viewed. The dashboard supplies data in a simple
manner, such as by showing data for a specific area by clicking the name of a prefecture.
