| Outline of Final Research Achievements |
It has been commonly mentioned that Regional Medical Care Zones (RMCZs) have been established to provide equal opportunities to receive adequate medical care for people in communities. With a view to see if this is being truly realized, we gathered data from four cities and three towns on 19 million invoices to medical insurers for fiscal years 2011 through 2013 after proper anonymization. We created a database for statistical analysis after matching the data from two different insurance systems: National Health Insurance and Elder Healthcare System.
Our analysis revealed that there is an inequality in the capacity of RMCZs in providing care; namely, there is a large difference in the proportion of patients seeking medical care outside their own RMCZs according to whether or not each RMCZ has a tertiary medical care institution within. Moreover, there was a large imbalance in the amount of medical expenses among RMCZs.
