Background: This study aims to analyze quality of and satisfaction with Korea medical services and identify factors affecting medical service satisfaction, revisit, and recommendation intention among international patients. Methods: Secondary analysis of survey data conducted by Korea Health Industry Development Institute from June 10th to July 17th in 2013 was done using multiple regression and logistic regression analysis. The 191 international patients from 9 medical institutions in Seoul were enrolled. Results: The results showed that international patients were satisfied with 85.6 points out of 100.0 points. International patients appraised higher in staff service rather than other services. Factors influencing medical service satisfaction were gender, religion, medical specialty, length of stay, and quality of medical services. Quality of medical service explained 29.8% of medical service satisfaction and especially, ‘doctor’s care’ and ‘communication and patient respect’ were significantly related to medical service satisfaction. Medical specialty had a significant influence on revisit intention. There were no statistically significant influencing factors of recommendation intention. Additionally, more satisfied patients were associated with higher revisit and recommendation intention. Conclusion: This study implies that quality of medical services is a critical factor for patient satisfaction and that satisfaction with medical services is an important factor for increasing revisit and recommendation intention among international patients. In addition, health care providers should consider cultural differences to enhance satisfaction with medical services for international patients. Therefore, multidimensional strategy is required to strengthen the cultural competency of healthcare providers.
