Objective: The purpose of this study was to analyze the difference of the outpatient service uses by marriage status.
Methods: Data was provided from the Korea Health Panel(KHP) collected by the National Health Insurance Service(NHIS) and Korea Institute for Health and Social Affairs(KIHASA) in 2013. The number of sample was 4,879 people. This study used Propensity Score Matching(PSM), Negative Binominal regression and Gamma regression analysis.
Results: there were significant differences in outpatient visits and outpatient medical expenses by the marital status. The average number of outpatient visits was 13 days for married women and 7 days for unmarried women after propensity score matching. The average amount of outpatient medical expenses was 231,269 won for married women and 153,009 won for unmarried women. The subjective health and the number of chronic diseases had significant effects on the number of outpatient visits. When the perceived subjective health was poor and the number of chronic diseases was higher, the number of outpatient visits was higher. The type of medical insurance had a significant effect on outpatient medical expenses only. Compared to NHI, outpatient medical expenses were lower for those receiving medical aid.
Conclusion: As the marriage rate decreases, it is necessary to cope with changes in medical care utilization. For this, it is important to understand the difference in the outpatient service uses between married and unmarried groups. as a result, There were significant differences in the number of outpatient visits and outpatient medical expenses by marital status even after controlling factors affecting medical use. In the Future, these findings of this study can be used as basic data for the diversity of research and the establishment of health policy.
