Abstract
This study was carried out to determine the factors affecting the trend and usage of Magnetic Resonance Imaging before and after the implementation of National Health Insurance. The research materials were the MRI Execution Data, Health Insurance Review Data, and Medical Expenses in the Health Insurance Data from a General Hospital located in Dae-jeon Metropolitan City from 2004 to 2013. The subjects of analysis were 3,754 people in 2004 (prior to the implementation of Health Insurance), and 4,107-8,603 people from 2005-2013(after the implementation of Health Insurance). In terms of analysis, a comparison of the use of MRI before and after implementation of the Health Insurance of User Characteristics and Provider Characteristics were taken as $X^2$, while factor analysis for the elements that affect MRI usage was carried out by Hierarchical Multiple Regression Analysis. According to the results of this study, the level of use decreased temporarily in the initial application stages of the national health insurance, but it soon increased. In particular, the inspection rates for women, the head and neck, those not subject to the application of the national health insurance, internal medicine, and the inpatients increased. The application of the national health insurance for MRI influenced the increasing inspection rates (P<.0001). As the inspection rate for the MRI increased, it is important to expand the application of the national health insurance to reduce the national health expenditure.
