This study aims to identify factors to affect regular utilization status of medical care in cardio-cerebrovascular patients. The research selected 770 cardio-cerebrovascular patients among surveyees from the Korea Health Panel 2010. We analyzed states of medical care utilization using descriptive statistics. Logistic regression analysis was used to examine the main factors associated with regular utilization status of medical care in cardio-cerebrovascular patients. In result, the significant factors associated with regular utilization status of medical care in cardio-cerebrovascular patients were age, education level, household income level. CCI, presence or absence of high risk drinking, and presence or absence of obesity. There's a high probability that patients aged between 60 and 69, equal to and higher than those of high school graduate in education level, upper middle class in household income, the higher CCI, absence of high risk drinking, presence of obesity utilize medical care services more regularly. Therefore, it is necessary to develop effective program and individualized approach for patients using lesser periodical medical care and patients with high risk drinking problem. In the future, these findings can be used an important data for healthcare policy and assessment.

In South Korea, few researches have been conducted into the incidence of injury diseases and into their demographic and sociologic characteristics. This research has estimated and analyzed the results of an questionnaire investigation carried out by the Korea medical panel (2008) and the social economic costs. In particular, an estimation has been conducted of social costs for each type of accident, injury and intoxication and of medical use for the injuries. For the future, it is necessary to develop concrete programs customized for age, education level, economic income and to continually implement injury prevention education, with a view to reducing the injury incidence and medical expenses; and also, individuals' participation in and social and national efforts are required for an efficient operation of the health insurance, for the purpose of reducing social and/or economic costs for injuries in South Korea.

Objectives: This study aimed to verify the impact of dental health care insurance coverage policy by analyzing the changes in dental care utilization and expenditures over 5 years from 2012 to 2016, when the dental health insurance coverage expansion policy was implemented. From the national cohort data collected by the Korea Health Panel Survey, a retrospective study was conducted for all household members using dental services. Methods: This study statistically verified the difference in the dependent variables by frequency analysis, chi-square test, t-test, and one-way analysis of variance (SPSS version 22, IBM Co. USA, p<0.05). Results: The annual utilization rate steadily increased from 23.4% to 26.1% between 2012 and 2016. Although there were differences in utilization rates by gender, age, and income level, patients kept using the dental services in 2016 regardless of the type of health insurance. The average annual copayment for patient expenditures (out-of-pocket amount) increased from ￦463,844 to ￦537,401 in 2012 and 2016, respectively. Of the dental care expenditures over 5 years, the ratio of uninsured expenses by the elderly decreased from 38.5% to 25.9%, and the national health insurance service coverage increased from 40.3% to 49.1%. Conclusions: Although this policy did not reduce overall patient expenditures, it has been found that there was a positive effect on the elderly and low-income groups; it increased the utilization and access to dental services.

This study is designed to demonstrate risk factors of unmet medical care for people with cerebrovascular disease. To do this, statistical analysis was performed by using hierarchical logistic regression analysis with SPSS/WIN24.0 program using Korean Medical Panel data in 2014. In the final model of the hierarchical logistic regression analysis, which is based on Anderson's Model, adjusted for the factors of the predisposing and enabling factors, the explanatory variables affecting the unmet medical development are gender, economic activity, income level, the experience of lying in a sickbed, restriction on activity, subjective health condition, and the number of chronic diseases. Based on the results of this study, the practical and policy implications for the effective management and treatment of cerebrovascular disease should be included in the countermeasures for cerebrovascular disease, a strategy to reduce the unmet medical incidence of cerebrovascular disease, in order to meet the medical needs, the necessity of comprehensive measures considering various dimensions of variables and the influential variables of unmet medical emergence have been suggested for the necessity of making a detailed service manual that can improve accessibility to medical services.

The objective of this study is to observe the efficiency of clinical performance on the supply and demand of medical resources in Korea. For the empirical analysis, we constructed the dataset on age standardized mortality rate, the number of physician, specialist, surgery, medical institution, ratio of general hospitals of 16 provinces in Korea from 2006 to 2013. The panel probability frontier model is employed as an analysis method and considered heteroscedasticity and autocorrelation of the error in panel data. In addition, the demographic and socioeconomic characteristics of the 16 provinces, unemployment rate, elderly population ratio, GRDP per capita, and ratio of hospitals in comparison to the general hospitals are used to find the effect on the technical efficiency of clinical performance on supply and demand of medical resources. The results are as follows. First, for the clinical performance, the supply side of human resources such as doctors and specialists and the demand side factors such as chronic illness clinic per unit population have a significant influence, respectively. Second, the technical efficiency of clinical performance on the supply and demand of medical resources of each input component was 59-70% in terms of clinical efficiency in each region. Third. estimates of technical efficiency of inputs that affect clinical performance showed a slight increase in all regions during the analysis period, but the increase trend decreased slightly. Fourth, the ratio of the elderly population and GRDP per capita have a positive influence on the technical efficiency of clinical performance on the supply and demand of medical resources. The difference of each efficiency by region is due to the regional differences of the input medical resources and the combination of them and the demographic and socioeconomic characteristics of the region. It is understood that the differences in technological efficiency due to the complexity of supply and demand of medical resources, demographic structure and economic difference affecting clinical performance by region are different.

This study examines the determinants of emergency care utilization and equity of access to care in elderly Koreans. Based on the data from the 2014 Korea Health Panel Survey, descriptive and logistic regression analysis was performed. The sample for this study was 1,313 individuals who participated in interviews. Predisposing factors such as age, sex, and education were significant determinants of emergency care utilization. Differences in need do not fully account for the original differences observed between subgroups of older Koreans. Health status was important determinant of older Koreans using emergency care services. Spending medical expense did not ameliorate the subgroup differences in the use of emergency care services. Nonetheless, spending medical expense remains a particularly important predictor of emergency care utilization. Health care reforms in Korea should continue to concentrate on insuring effective universal emergency care, implying that all older Koreans with need receive effective coverage. Future study is also needed to understand the access barriers that may exist for the selected demographic subgroups, i.e., those over 75, women, less educated persons, and those with higher medical expense.

In this study we investigated the factors determining people's decision on whether to subscribe to private health insurance, on how many private health insurances they subscribe to and the average amount of monthly payment from subscribers of private health insurances. For analysis, logistic regression analysis and multiple linear regression analysis were conducted on the sample of 8,167 people using 2008 Korean Longitudinal Study of Ageing(KLoSA) data. From the analysis, whether to enroll in private health insurance is found to be greatly influenced by population and socioeconomic factors as well as regular exercise, smoking, cognitive function scores, subjective health status, hospitalization, the number of outpatient services, free primary health screenings benefits. We also found that number of private health insurances purchased is affected by age, household income, subjective health status, drinking, free primary health screenings benefits and that the average amount of monthly payment for private health insurances purchased is influenced by age, marriage status, economic activities status, subjective sense of hierarchy, household income, drinking, hospitalization. This study is expected to contribute to show the healthy role of private health insurance so that the desirable direction in expansion of health security policy in Korea can be explored further.

Although the number of people insured by private health insurance in Korea is steadily increasing, the household burden or the status of multiple purchasing for private health insurance has not been addressed. In this study, data of the 2011-2018 Korea Health Panel Survey was used to examine the purchasing trend of Korean households' private health insurance. Households with more than three private health insurance per household member were defined as the 'poly-purchases'. The logit model was applied to analyze factors associated with poly-purchase of private health insurance using 2018 cross-sectional data. From 2011 to 2018, the number of insurances purchased by Korean households increased (4.0 to 4.6), the number of insurances per capita increased (1.3 to 1.6), and the proportion of the poly-purchasing households increased (5.2% to 10.8%). As a result of logit analysis, the probability of poly-purchasing was increased when the household head was a woman, with a high level of education and income, and when the job of the household head was a service or sales. Poly-purchasing was less likely when the family was subsidized with Medical Aids and suffered with more chronic diseases. The results of this study serve basic evidence for establishing policies regarding private health insurance, such as establishing the relationship between public and private insurance.
