Background: While there are many studies estimating the effects of private health insurance on various types of health care utilization, few have examined how such effects change in conjunction with important policy reforms in national health insurance (NHI). This study examined how the effect of private health insurance (supplemental and fixed cash benefit) on high-cost outpatient imaging test utilization changed following the expansion of magnetic resonance imaging (MRI) coverage in 2018, which is a key example of the NHI benefit expansion policy in recent years. Methods: Data from the 2017 and 2019 Korea Health Panel Survey, which contained information about healthcare utilization before and after the expansion of MRI coverage in 2018, were used. The incremental effect of private health insurance on high-cost outpatient imaging test utilization for each period were quantified and compared, with special attention given to the type of private health insurance. Results: While people with supplemental private health insurance were more likely to use high-cost outpatient imaging tests than those without, both before and after the expansion of MRI coverage, the incremental effect increased from 1.6% points in 2017 to 2.5% points in 2019. Conclusion: Benefit expansion in NHI does not necessarily reduce disparities in the use of health care between private health insurance subscribers and non-subscribers. The results of our study also suggest that the path through which private health insurance affects healthcare utilization may not be limited to the price mechanism alone but can be more complex.

Background: The purpose of this study was to analyze the effect of national health insurance coverage of Chuna therapy in April 2019 on the costs and service uses in automobile insurance. Methods: This study used the claim data from Health Insurance Review and Assessment Service. A total of 189,912 inpatients and 1,550,497 outpatients who received Chuna therapy covered by automobile insurance in oriental medical institutions were included. The analysis period was from July 2018 to December 2019, and a total of 18 months before and after April 2019, when Chuna therapy was covered by national health insurance. Interrupted time series analysis was applied to analyze the impact on the costs and service uses of Chuna therapy in automobile insurance before and after April 2019. Results: From July 2018 to December 2019, for 189,912 inpatients the cost and the number of times for Chuna therapy per capita were increased by 22.0% and decreased by 7.3% respectively right after the implementation of the policy. In the case of 1,550,497 outpatients, the cost of Chuna therapy per capita tends to be increased by 0.4% in overall study periods and increased 28.4% immediately after the implementation of the policy. Meanwhile, the number of times and visits for Chuna therapy per capita tends to be increased by 0.4% in overall study periods but decreased by 0.4% after the implementation of the policy. Conclusion: Results suggest that if the national health insurance coverage of oriental medicine services increases according to the policy stance for benefit expansion in national health insurance, the criteria for providing national health insurance benefits should be considered with the comprehensive impacts on the costs and service uses of automobile insurance.

Background: Korea set up a new diagnosis-related group as a demonstration project in 2009. The new diagnosis-related group was reformed in 2016. The main purpose of the study is to identify the effect of reform on coverage of national health insurance. Methods: This study collected inpatient data from a hospital that contains medical information and cost from 2015 July to 2016 June. The dependent variable was the coverage of national health insurance. The dependent variable was divided by total, internal medicine partition, surgical partition, and psychiatric partition. To analyze the effect of the reform, this study conducted an interrupted time series analysis. The final sample included 23,695. Results: The health insurance coverage of internal medicine has the highest, followed by surgery and psychiatry. The health insurance coverage of bundle payment is higher than that of unbundled payment. The proportion of bundled payment and non-benefit decreased and the proportion of unbundled payment increased. The coverage of national health insurance significantly increased after policy reform in internal medicine partition (p-value=0.0356). Conclusion: The results of the study imply that policy reform enhanced the coverage of national health insurance in internal medicine. The government needs to monitor side effects such as an increase of unbundled payment.

Background: Informal care is increasingly recognized as placing a significant burden on the lives of family caregivers. The purpose of this study is to investigate factors related to family caregivers' burden with the community-dwelling disabled elderly under the long-term care insurance system, using the Stress Process Model developed by Pearlin (1990). Methods: Total 1,233 family caregivers with the disabled elderly, using the long-term care services in their home from May to June 2009, completed questionnaires finally. The questionnaire of this study consists of a total of 32 questions, including 11 questions related to background and context, 17 questions related to objective stressors, and 4 questions related to coping resourses. Family caregivers' burden is measured by the Korean Revised Caregiving Appraisal Scale (K-RCAS, Cronbach's alpha=0.86). To investigate factors related to family caregivers' burden, multiple regression analysis was conducted. Results: The average score of caregivers' burden was 22.0 (${\pm}6.12$). In multiple regression analysis, there were statistically significant factors affecting on the family caregivers' burden, that are related to background and context (region, living status, education level, relationship with beneficiary), objective stressors (duration of caregiving), coping resourses (caregiver's health status). Conclusion: This study found that family caregivers experience a considerable burden. The findings suggest that policies must be taken to relieve family caregivers of their duties temporarily, and to support them with counselling and education.

In the process of promoting policies to strengthen health insurance coverage, the relationship between public health insurance and private health insurance, along with the management of non-benefit, is also emphasized as a policy issue. First, the concept and scope of non-benefit were comparatively analyzed by country. Second, the interaction between the public and private health insurance was classified as 'large or small,' and the government's regulation and management policy on private health insurance was classified as 'strong or weak.' Korea has relatively smaller benefits covered by public health insurance, higher copayment expenses, and more areas and scope of non-benefits. In countries where the interaction between public and private health insurance is small, private health insurance-related policies are weak. And in countries with large interactions had public-private partnerships and the government's management policies were also strong. On the other hand, Korea has a large interaction, but the actual structure of cooperation between public and private insurance and management policies were weak. Because the non-benefit sector in Korea is relatively wide, it is difficult to manage compared to other countries where the concept of non-benefit is limited. In addition, the health authorities rarely perform the role of supervision over private health insurance, and they have so few linkages and cooperation for public-private insurance. Therefore, practical policy enforcement is necessary to achieve the easing of the burden of national medical expenses through linkage and cooperation of public-private health insurance with reference to relevant other countries' cases.

Health insurance has gone far toward solving Korea's health related problems through thirty years. Health Insurance as social security system has a role of national system to secure national health. But there are many problems in health insurance. There is a dispute about many issues, coverage of health security, compulsory appointment of health insurance organization, coverage and level of health insurance benefit, decisionmaking right of health insurance price, examination of health insurance etc. Generally, the opinion for health insurance policy to be leaded by nation sets against the opinion to be leaded by private sector. It is necessary to study politics of law, constitute law and comparative law for rational solving these problems. If desirable setting of health law system can be made, legal system must be set during a long time and be discussed synthetically in different standpoint.

It was revealed that 67.5% of the subjects continued to receive prenatal care at the same medical institutions from the diagnosis of pregnancy to the delivery. The study also showed that the total expenditure of prenatal care per pregnant woman was 700,000 Korean Won (KRW) on average and the insurance coverage rate stood at only 20%. Pregnant women living in metropolitan area spent more on prenatal healthcare expenditure than those who living in medium-sized city or rural area. Conclusion: The results of this study implies that the government needs to provide pregnant women with continuous support by increasing health insurance coverage for prenatal care. Especially, it is considered to provide more support to the pregnant women residing in medically underserved areas.

Korea's social health insurance system was introduced in 1977, which has made a universal coverage possibly by July 1989. Korean government had pursued a single objective for the last decade to put the whole population under the coverage of medical security, and the objective was achieved within 12 years. The rapid accomplishment is primarily due to such factors as limited benefits, high copayment rate, low contributions as well as rapid economic growth. There are several sources of pressure for the implementation of social health insurance such as health professional group, labor unions, politicians, international organizations etc.. However it is important to look at the feasibility of social health insurance. Among other things, it is necessary to identify the administrative infrastructure of insurance system and to assess income for source of fund. As many developed countries, Korea began to apply health insurance to the employees of the large firms, and the expansion based on employment status. Thus the several funds system was inevitable according to the gradual expansion strategy. However many persons had criticized several funds system in respect with equity and efficiency aspects. In the short history of the Korean health insurance, whether one fund or sever or funds had been the most controversial issue. In Febrary 1999, the National Assembly passed the act of one fund system. From July 2000 separate funds will be unifed under new health insurance scheme. In this study we will analyze the policy making process on implementation, expansion and integration of health insurance system of Korea. And also analyse problems related to policy making.

To vitalize the link program of Korean long-term care insurance system to community-based services for non-eligible people, we analysed the claim data from the Korean National Health Insurance Corporation (NHIC), and conducted a questionnaire survey to charging employees of elderly service department at local governments. The subjects were all 81,377 people, 57,454 of them were arranged to community-based services. The link program was more necessary among the missed subjects rather than the arranged people due to the need for physical or psychological assistance. By the result of the survey to the local government employees, 59.5% of subjects responded their proportion of link service was over 10% and under 20%, and 54.3% of them responded their job boundary are not clear. Major type of linking was notification the subject list to local government, 91.4%; proportion of periodical notification on the status of their service link were 57.1%, only 7.1% were followed to manage after the link. Difficult factors at the link process were pointed out the overload by other side work, deficiency of resources, rigidity of priority of link, and so on. Considering these results, to vitalize the community-based services to the non-eligible people, it may be essential the active participation of the subjects, construction of parts working in coordination among the institutions including NHIC, local governments, and service providers; development of various services for maintenance or promotion of the non-eligible peoples' health and functional status; and active participation of institutions from the third sector, and so on.

Social solidarity, equity in financing, and efficiency in administration have been core issues in the development of Korean health insurance reformation since 1988. This study is to investigate the trend of administrative cost in Korean National Health Insurance from various aspects. For the analysis of administrative cost, the expenditures of each insurance society and the National Health Insurance Corporation are divided into 4 items of (1) insurance benefit, (2) administrative cost, (3) an agency provision accounts, (4) other expenses, and then they are reorganized. The analyses based on 5 types of the health insurance administrative cost showed that efficiency in administration has been improved generally. We, however, should consider qualitative aspects such as customer's satisfaction with health insurance administration, prompt service, control of unjust expenditure (unjust claims), and provision of medical service including health consultation in assessing efficiency of administration. And, in order to connect the administrative costs of health insurance with efficiency, we need to give a fundamentally new definition, which can contain elaborateness of expenditure in details including the structure and evaluation method of administrative costs. It may be necessary to develop new indicators or analyzing methods hereafter.
