Launch of Disease/Injury and Drug Use Statistics Dashboard Service Using Medical Big Data

(JAST) has developed a statistics dashboard service called Medicine Tiger concerning theuse of drugs for diseases and injuries and started providing this service on April 9, 2024. The new service was developed withthe cooperation of Ataru Igarashi, an associate professor at Yokohama City University, and is for the use of anyone who wants

Background

JAST has been involved with a variety of joint research activities with universities and companies for the purpose of utilizing
medical big data. As these activities took place, JAST discovered the enormous expense of surveys that are part of research
programs in order to identify drug prescription patterns for specific diseases and injuries and to determine the scope of diseases
and injuries for which specific drugs are prescribed. JAST realized that cutting the cost of surveys would lower the cost ofresearch activities, facilitate the more efficient use of resources and raise the speed of R&D programs.
To accomplish this goal, JAST developed the Medicine Tiger dashboard, a service for the visualization of statistical dataobtained from JAST’s REZULT medical big data platform.
Medicine Tiger uses the Tableau business intelligence tool for data visualization. A patent for this new service is pending.

Medicine Tiger

By using health insurance invoice data, Medicine Tiger can calculate the rates at which drugs were prescribed for specificdiseases or injuries as well as rates at which diseases or injuries are linked with specific prescription drugs. Medicine Tig erthen generates a list of the top ten. Data can be categorized by dates, gender, age, type of prescription and region. This makes
it possible to see with ease differences in prescription patterns when changing parameters. Data analysis concerning
differences between prescription drugs received at hospitals and at pharmacies is possible too. In addition to performing thesebasic functions, Medicine Tiger can be customized to match the requirements of individual customers.
