The purpose of this study was to verify that the three types of medical service satisfaction, patient-oriented satisfaction, and the willingness to reuse Korean hospitals differ depending on the characteristics of foreign patients. Second, we investigate the factors affecting these four variables. The main analysis results shown in this study are as follows. First, most foreign patients were found to be highly satisfied with Korean hospital doctors and patient-oriented hospitals. In addition, more than 75 percent of foreign patients were willing to reuse Korean hospitals in the future. Second, a regression analysis of variables that affect satisfaction with Korean hospital doctors showed that the presence of long-term diseases affected. Specifically, if there is a disease in the long term, the satisfaction level of Korean hospital doctors is high. The factors that affect foreign patients satisfaction with the Korean hospital system were income and health conditions. The lower the income of foreign patients, the higher the satisfaction with the Korean hospital system in the case of positive perception of their health conditions. Meanwhile, the impact on the satisfaction of foreign patients with patient orientation in Korean hospitals was on whether they lived in Korea and recognized their health conditions. Foreign patients living abroad, not domestic residents, and foreign patients with positive perceptions of their health conditions showed high satisfaction with the patient-orientedness of Korean hospitals. Third, the regression analysis was conducted to identify the factors affecting the willingness of foreign patients to reuse Korean hospitals, and found that the medical expenses were borne by themselves, doctor satisfaction, and hospital system satisfaction. Foreign patients who do not pay for medical expenses showed high willingness to reuse Korean hospitals, while foreign patients with high satisfaction with Korean hospital doctors showed high willingness to reuse Korean hospitals.
