National Health Insurance Service(NHIS) provide care-plans for beneficiaries in the long-term care insurance(LTCI) systems that help them use LTC services appropriately. The care-plan includes recommendations for the most adequate type of care (gold standard) for beneficiaries. This study develops a decision-support system to determine the appropriate type of care plan. To develop a model, we used a data set that well-trained assessors in the NHIS investigated as a gold standard for beneficiaries: nursing home care, home-visit care, home-visit bathing, home-visit nursing, or day and night care. The decision-support system was established through a decision-tree model, because it may be easy to explain the algorithm of a decision-support system to working groups and policy makers. Our results might be useful in evidence-based care planning in an LTCI system and contribute to the efficient use of LTC services.

Purpose: The purpose of this study is to examine the relationship between the income level and the healthcare utilization by health insurance type in all cancer patients in year 2005. Methods: The target population was cancer patients with health insurance who used healthcare as a diagnosis code (C00-C97) from January 1 to December 31 of 2005. The Korea Central Cancer Registry Center's Cancer Patient Registry Data, the list of cancer patients of the National Health Insurance Corporation, and the claim data of the Health Insurance Review & Assessment Service were used. The I was the wealthiest, followed by II, III, IV. The V was the poorest in this study. For the analysis, the $x^2$-test, ANOVA (and Kruskal-Wallis test), and regression were used. Results: Outpatient and hospitalization medical expenses, and outpatient visit days of cancer patients with self-employed health insurance were highest in I (p<.001, respectively), and the hospitalization days were the highest in II (p<.001, respectively). Outpatient and hospitalization medical expenses, and outpatient visit and hospitalization days of cancer patients with occupational health insurance were the highest in I (p<.001, respectively). Outpatient and hospitalization medical expenses, and outpatient visit and hospitalization days in cancer patients were higher in I compared to V, and higher in II and III, IV compared to V (p<.001, respectively). Conclusion: Supporting plan for cancer patients' outpatient healthcare utilization are necessary. Moreover, we should make specialized strategy for low income cancer patients with self-employed health insurance when we develop quality improvement policy for inpatient service.

Objectives: The purpose of this study is to examine the magnitude of and the factors associated with the downward mobility of first-episode psychiatric patients. Methods: This study used the claims data from the Korean Health Insurance Review and Assessment Service. The study population included 19 293 first-episode psychiatric inpatients diagnosed with alcohol use disorder (International Classification of Diseases, 10th revision [ICD-10] code F10), schizophrenia and related disorders (ICD-10 codes F20-F29), and mood disorders (ICD-10 codes F30-F33) in the first half of 2005. This study included only National Health Insurance beneficiaries in 2005. The dependent variable was the occurrence of downward mobility, which was defined as a health insurance status change from National Health Insurance to Medical Aid. Logistic regression analysis was used to assess factors associated with downward drift of first-episode psychiatric patients. Results: About 10% of the study population who were National Health Insurance beneficiaries in 2005 became Medical Aid recipients in 2007. The logistic regression analysis showed that age, gender, primary diagnosis, type of hospital at first admission, regular use of outpatient clinic, and long-term hospitalization are significant predictors in determining downward drift in newly diagnosed psychiatric patients. Conclusions: This research showed that the downward mobility of psychiatric patients is affected by long-term hospitalization and medical care utilization. The findings suggest that early intensive intervention might reduce long-term hospitalization and the downward mobility of psychiatric patients.

Amid the rapid transitions in both local and international markets, the Korean dental industry is facing more challenges than at any time in its history. This paper tried to address some of the key issues faced by the industry as well as the policy issues and I direction of implementation that the Korean Dental Association (KDA) is expected to tackle. First, the direction of reforming the country's health insurance system was examined with emphasis on the expected changes in and improvement of the fee-for-service reimbursement system (FFSRS) and medical reimbursement system (MRS). With FFSRS, the most urgent issue would be ameliorating the current lop-sided, unreasonable reimbursement system that prevents suppliers from voicing their opinions. To help achieve that goal, the limited authority and responsibility of the president of National Health Insurance Corporation (NHIC) as one of the contract-making parties must be clarified. In addition, the functions of NHIC's Health Insurance Finance Committee must be restricted; at the same time, the panel organization of the Health Insurance Policy Review Committee needs to be reformed to embrace greater democracy. As with MRS, the government is considering a block budget bill to help promote efficiency in employing and managing the health insurance fund. Policymakers must understand that the implementation of such proposal could exacerbate an already dire situation. Improving MRS requires meeting the following preconditions: (a) the structurally vicious cycle of small charge-small salary needs to be resolved, and a certain percentage of fee raise must be guaranteed on a yearly basis to help adjust the fee system to a more realistic level; (b) the supply-and-demand balance in producing health care professionals must be improved including the prevention of oversupply of doctors, nurses, etc., and; (c) institutional strategies must be provided to enhance the quality of medical care and ensure academic advancement in health care disciplines.

This study was conducted to examine the trend of national health insurance service use with relation to pregnancy, childbirth, and the puerperium among pregnant and postpartum women older than 35 over the last decade. A descriptive analysis was conducted, using the data which were drawn from the "nationwide claim database of Korean National Health Insurance Corporation(NHIC)". Data were composed of the total cases related to pregnancy, childbirth, and the puerperium (International Classification of Disease, $10^{th}$revision [ICD-10] codes O00-O99) from 2001 to 2008. During 2001-2008, the number of pregnant and postpartum women older than 35 had continuously increased and the percentage of them also had increased in both hospital and ambulatory care. There are similar trends in their total use of national health insurance service and total expenditure. According to demographic characteristics, there was the biggest increase of the percentage in residents in large cities, self-employed workers, ones in the highest income level. According to ICD-10 codes, there was the biggest increase of the percentage in O10-O16 (oedema, proteinuria and hypertensive disorders in pregnancy, childbirth and the puerperium). According to the major prevalent disease, there was the biggest increase of the percentage in O60 (preterm labor and delivery). Throughout the past decade, the necessity has been emphasized of supporting pregnant and postpartum women older than 35. But in maternal and child health care, they are in an early stage of development. The findings of this study would be helpful in developing the support programs for the aged pregnant and postpartum women.

According to rapid increase of the population of senior citizens, there has been growing concern of Long-Tenn Care(LTC) services recently. Long-Tenn Care services, however, haven't been established systematically in Korea and the supply of LTC services is not sufficient despite the increase in the current social demand. This study aims to estimate the 'Willingness to Pay(WTP)' for LTC insurance which the government plans to introduce by means of social insurance, using Contingent Valuation Method(CYM). In addition, this study analyzes the factors affecting WTP for LTC insurance. An interview survey was carried out to derive WTP for LTC from 450 people who lived in Seoul aged 20 and above during the period from 16th to 21st of June 2003. Double-Bounded Dichotomous Choice Method was applied among several CVMs available to estimate both use value and no-use value of goods. There was pilot survey carried out prior to the main survey. The results show that the average monthly. WTP for LTC provided in home and residential setting is 18,192Won and 19,293Won, respectively. In the case of home care, WTP goes higher depending on reliability of LTC insurance policy and need for LTC insurance, as well as marital status, education and average monthly income. On the contrary, WTP is conversely affected by higher age and higher bids. In the case of institutional care, the factors affecting WTP are similar to those of home care, except age. This study followed NOAA's suggestions generally and the value derived through survey could be reliable. However, there can be the least bias in the process of survey because the CVM should be used under the supposed circumstances. Despite those limitations, it can be concluded that the amount the citizens are willing to pay for LTC is high enough to meet the costs needed to provide LTC.

This research attempts to calculate the vertical equity of National Health Insurance Contribution of locally provided policy holders by abilities to pay. Also, this longitudinal study examined the influence of abilities to pay and demographic characteristics on the health insurance premium. Using data from the Korea Welfare Panel Study, this study followed the self-employed households who continued to participate in the survey from 2011 to 2015. Kakwani's index of progressivity was measured as a measure of vertical equity and panel regression analysis was conducted by STATA program. The results of this research are as follows. First, from 2011 to 2015, the values of kakwani's index were negative according to composite income, which meant some levels of regressiveness of contribution. Secondly, panel regression analysis showed that the lowest household of composite income had a significantly negative effect on premiums, which also meant regressiveness. Based on the results, the author suggested political discussions on reorganizing the system of imposing the National Health Insurance contribution.

In accordance with the government's plan to expand the national health insurance (NHI) coverage for severe diseases such as cancer, heart disease, cerebrovascular disease, and rare and incurable disease, the diagnostic ultrasound services have been covered by NHI from October 1, 2013. The quality is very important factor in providing diagnostic services because they influence on the diagnosis, treatment, and outcome of diseases. In particular, equipments and health care providers plays an important role in providing qualitative services. The purpose of this paper is to examine the major feature of ultrasound services covered by health security system and to review quality assurance policies in other countries such as Australia, Japan, the USA, and Canada. In addition, we assessed the implication of those policies. We especially put emphasis on the types and qualifications of healthcare professionals and measures to manage equipments. All countries have reviewed on policies to promote the quality such as educational requirements of professionals or restrictions on the duration of equipment usage. Various measures should be implemented to assure the qualitative ultrasound service.
