Background: Bankrupted households have recently been increased due to excessive medical expenditure in Korea. They have not been protected from economic risk when household's member has severe diseases that need a lot of money for treatment. Purpose of this study examines policy effect by comparing unmet needs' change of policy object households and non-object groups. Methods: We used Korea Health panel 2nd 4th data collected by Korea Institute for Health and Social Affairs and National Health Insurance Service. Analysis subjects were 381 households (pre-policy) and 393 households (post-policy) that had cancer and cardiovascular and cerebrovascular diseases. Since it was major concern that estimates benefit strengthening policy started by certain time, we setup comparing households which had diabetes, hypertension disease. Comparison subjects were 393,247 households, respectively and we evaluated policy effect using difference in difference (DID) model. Results: Although unmet needs of policy object households were higher than non-object groups, policy execution variable affected negative direction. But interaction-term which shows pure effect of policy was not statistically significant. We utilized multi-DID model to examine factors affecting unmet needs causes. Copayment assistance policy did not significantly affect households that responded to 'economic reason,' and 'no have time to visit' for unmet needs causes. Conclusion: The second copayment assistance policy did not significantly give positive effect to beneficiary households than non-beneficiary groups. When we consider that primary purpose of public insurance guarantee high medical expenditure occurred by unexpected events, it needs to deliberate on switch of benefit strengthening policy that can assist vulnerable people. Also, we suggest that government forward a policy covering non-reimbursable medical expenses as well as switch of benefit strengthening direction because benefit policy do not affect non-covered medical cost which accounts for quarter of total health expenditure.

Unmet healthcare is an important indicator to measure accessibility of healthcare services. To examine the latest status of unmet healthcare needs in South Korea, the four different data which is composed of nationally representative sample of South Korean population were used; the Korea Health and Nutrition Examination Survey (KNAHANES, 2007-2019), the Community Health Survey (CHS, 2008-2019), the Korea Health Panel Survey (KHP, 2011-2017), and the Korean Welfare Panel Study (KOWEPS, 2006-2019). The proportion of individuals reporting unmet healthcare needs were 5.8% (KNHANES), 5.3% (CHS), and 11.6% (KHP). Annual percentage change (APC) which identifies trend for the follow-up period was -9.5%, -8.0%, and -6.5%, respectively. The proportion of individuals reporting unmet healthcare needs due to cost were 1.1% (KNAHANES), 0.7% (CHS), 2.4% (KHP), and 0.4% (KOWEPS). The APC was -10.5%, -14.2%, -12.2%, and -19.6%, respectively. Compared to last year, the rate of unmet healthcare needs has declined in general. However, the low-income and the elderly population were reporting the highest rate of unmet health care needs, and the disparity between lowest and highest groups were remained. These results suggest that adequate benefit coverage is needed for low-income and elderly population.

The objective of this study is to empirically analyze the relationship between sea temperature and jellyfish blooms. Ever since the 2000s, jellyfish population has been dramatically increased, which brought negative influence on the national health and the fisheries activities. Jellyfish blooms have been recognized as an effect of climate change, but there has been no empirical evidence to support such relationship. In this paper, the relationship between sea temperature and jellyfish blooms has been analyzed by using the regional jellyfish monitoring data and coastal stationary observing data of National Institute of Fisheries Science. Since the dependant variable carries left censoring issues, we used the panel tobit model. Our results indicate that there are statistically significant positive relationship between sea temperature and jellyfish blooms.

This study aims to investigate the main factors that affected the government health expenditures in Gulf Cooperation Council (GCC) countries (Kingdom of Saudi Arabia (KSA), United Arab Emirates (UAE), Oman, Qatar, Bahrain and Kuwait), during the period from 2005 to 2019. The study employs a panel data technique in order to monitor the pooled determinant variables of healthcare expenditures in these countries. The study's results indicate, by using FMOLS approach for panel data, that the average healthcare expenditures per capita in GCC countries have a positive and a significant relationship with the government revenues, the size of the population, and the governments' public debt. The positive and the significant relationships of governments' public debt may be explained even if the governments of the GCC countries suffer from a budget deficit; the GCC countries continue to increase the healthcare expenditure. The study suggests that the policymakers of the GCC countries must take into consideration those variables when they develop their healthcare policies. Also, the GCC countries urgently need to have high levels of foreign exchange reserves to maintain the expected level of spending on the healthcare sector, because their public revenues depend mainly on the oil revenues, which are fluctuating continuously.

Catastrophic health expenditure refers to measure the level of the economic burden of households due to medical expenses. The purpose of this study was to examine the proportion of households that experienced catastrophic health expenditure between 2006 and 2019 using available data from the National Survey of Tax and Benefit (NaSTaB), Korea Health Panel (KHP), and Households Income and Expenditure Survey (HIES). Trend test was used to analyze the proportion of households with catastrophic healthcare expenditure. The households experienced a catastrophic health expenditure of 2.44% in 2019 using the NaSTaB data. Trend analysis was significant with the decreasing trend (annual percentage change [APC], -4.49; p<0.0001) in the proportion of households with catastrophic health expenditure. Also, the results of the 2017 KHP and the 2016 HIES showed 2.20% and 2.92%. The trend was significantly increased in the KHP (APC, 1.79; p<0.0001) and the HIES (APC, 1.43; p<0.0001). Therefore, this study suggests that further public healthcare interventions to alleviate the burden of catastrophic health expenditure, especially for low-income households, are needed.

Objectives : This study was to investigate the effect of socioeconomic factors of smokers on their smoking cessation plans, using Korean Welfare Panel data. Methods : Of the 16,664 subjects who responded to the 10th Korean Welfare Panel Survey, 2,246 respondents who answered that they were currently smoking were included in this study. Results : The variables that affected smoking cessation plans were female, low education level, low level of smoking per day, and more than 24 hours of smoking cessation experience. Conclusions : Expanding the smoking cessation program for women, preventing smoking in schools and providing smoking cessation education will likely have a positive effect on smoking cessation plans. In addition, it would be helpful to increase the amount of smoking cessation support aimed at reducing the amount of cigarettes smoked per day and continuing smoking cessation for more than 24 hours.

In order to strengthen assurance of National Health Insurance, co-payment should be reduced. This can happen with collaborative efforts of patients, medical institutes, and government altogether at the same time. This research applied Dutton(1986)'s medical service research model with high R-square, and analyzed 2008 Korea Health Panel Data (Beta Version 1), that was examined by Korea Institute for Health and Social Affairs and National Health Insurance, in order to figure out influential variables on co-payment. In result of Multiple Linear Regression Analysis, R-square was 46.7%, the older the age, the patients who had surgery, the longer days of hospital treatment are, the higher gross income of a household is, the more hospitalized in upper grade general hospitals, and the more upper grade rooms and selecting a doctor are used. The results have statistical significance. When conducting research applying medical service research model, there is a need to apply Dutton(1986)'s medical service research model with high R-square. In order to strengthen assurance of National Health Insurance, first conditions should be that patients are hospitalized in upper grade general hospital, and at the same time, are patients who had surgery with long stay of hospitalization. In addition, if proven that patients used upper grade rooms and selecting a doctor due to lack of regular treatment and rooms, for certain number of days of such hospitalization, it is suggested to be provided with health care insurance in upper grade rooms and selecting a doctor in calculating co-payment limit.

Catastrophic healthcare expenditure refers to out-of-pocket spending for healthcare exceeding a certain proportion of a household's income and can lead to subsequent impoverishment. The aim of this study was to investigate the proportion of South Korean households that experienced catastrophic healthcare expenditure between 2006 and 2020 using available data from the National Survey of Tax and Benefit (NaSTaB), Korea Health Panel (KHP), and Households Income and Expenditure Survey (HIES). Trend test was used to analyze the proportion of household with catastrophic healthcare expenditure. In the NaSTaB 2020 data, households who experienced catastrophic health expenditure was 1.73%. Trend analysis was significant with the decreasing trend (annual percentage change [APC], -5.55; p<0.0001) in the proportion of households with the catastrophic health expenditure. Also, in the 2018 KHP and the 2016 HIES, households who experienced catastrophic health expenditure was 2.21% and 2.92% respectively. In contrast, the trend was significantly increased in the KHP (APC, 0.55; p<0.0001) and the HIES (APC, 1.43; p<0.0001). Therefore, the findings suggest the need to strengthen public health care financial support and monitor catastrophic healthcare expenditures, especially for low-income group.

Objectives : This study aimed to analyze the characteristics of uninsured herbal medicine(UHM) users and the economic and social barriers of UHM utilization. Methods : We used the Korea Health Panel Data, representative national survey on medical utilization and cost, provided by National Health Insurance Service and Korea Institiute of Health and Social Affairs. The frequency analysis was used to identify the characteristics of the respondents, and the cross-analysis (${\chi}^2-test$) was used to verify the relationship between their characteristics and the usage of UHM. In order to analyze the determinants of using the UHM considering the individual's characteristics, logistic regression analysis and multiple regression analysis were conducted for those who used the Korean medicine (KM) outpatient service in 2015. Results : The usage of UHM was significantly lower for those (1) who's age of 20 to 65; (2) who have the university or higher education degree; (3) who live in Jeju province, and (4) who bought the herbal medicine for other health related purposes. On the other hand, the usage of UHM for those (1) who have the first quintile of household income; (2) who have the chronic respiratory disease; (3) who have been taking the medicine for health promotion purpose for more than 3 months and (4) who have purchased the food which has health promotion function was significantly higher than others. The patients who have chronic musculoskeletal diseases accounted the most among the UHM users. Conclusions : There was the considerable inequality in the usage of UHM among household income groups, which provides policy rationale for UHM to be covered by national health insurance. To facilitate the coverage expansion, restrictive covering model can be considered for children and adolescents, or for patients with muskuloskeletal diseases who have the high demand for UHM.

Unmet healthcare needs do not end with the phenomenon itself, but lead to possibilities of increased severity of illness. Missed opportunities for treatment at the right timing increase possibilities of complications, and affect prognosis of disease. To examine current status and trends of unmet needs in Korea, we used data from four sources: the Korea National Health and Nutrition Examination Survey (KNHNES, '2007-2016); the Community Health Survey (CHS '2008-2016); the Korea Health Panel Survey (KHP '2011-2014); and the Korean Welfare Panel Study (KOWEPS '2006-2016). The proportion of individual reporting unmet healthcare needs as of 2016 was 8.8% (KNHNES), 11.5% (CHS), and 12.8% (KHP, as of 2014). Annual percentage change which characterizes trend for the follow-up period was -9.9%, -3.1%, and -1.3%, respectively. The proportion of individuals reporting unmet healthcare needs due to cost was 1.8% (KNHNES), 1.5% (CHS), and 3.0% (KHP). The proportion of households reporting unmet healthcare needs due to cost was 1.0% (KOWEPS). Annual percentage change was -10.0%, -15.2%, -5.4%, and -17.5%, respectively. Low income populations had more unmet healthcare needs than high income populations. Therefore, in order to improve unmet healthcare needs, it is necessary to focus on low income populations.
