Abstract

|
Objectives: The purpose of this study was to analyze whether there are differences in medical expenses according
to medical security type in the use of medical services with high disease burden such as coronary intervention.
Methods: Chi-square test and covariance analysis(ANCOVA) were conducted to identify the differences in the
characteristics and costs according to medical security type of 1,904 patients who underwent coronary intervention
in a university hospital from 2011 to 2012. Hierarchical regression analysis was conducted to determine whether the
cost affects medical expenses.
Results: In the medical aid group, the proportion of women, those without a job, those without a spouse, and
those who received hemodialysis was high, length of stay was high, patients using the emergency room and those
who died was high.
The medical aid patients were significantly higher in the non-benefit medical expenses, optional medical
expenses, physician and admission, meals, medications and injections. National health insurance patients were
significantly higher in procedure. The medical security type was found to be significant as a variable affecting the
medical expenses.
Conclusions: Provision of medical expenses should be managed in advance by providing prevention and
education services for the vulnerable, and care services in the region should be provided to suppress the occurrence
of medical expenses due to the increase in the number of days spent. In addition, it is necessary to support medical
expenses to prevent unsatisfactory medical services from occurring for non-benefit and optional care.
