As cost pressures have escalated, policy makers, politicians, health care providers and families have tried to devise ways to reduce health care costs. While originally developed to enhance patient control and to provide better care at the end of life, hospice care has recently received significant attention as a mean of reducing health care costs. As a program providing care for patients who are dying at their homes, hospice has expanded slowly since the opening of the first hospice in Korea in 1963. Therefore, a variety of services that responds to the needs and concerns of many dying people and their families is limited The purpose of this study was to determine the potential cost savings at the end of life among patients who used home hospice compared with the patients who received institutional care in Korea. This study used a retrospective, descriptive design. The sample for this study included 46 patients who died of lung cancer: 25 patients who received home hospice care and 21 patients who received institutional care. Data on patient characteristics, kinds and frequencies of provided treatment and nursing services, and hospice and hospital charges during the last month before death were collected. Cost of care was measured by the average cost per patient per day in the last month of life. The results of the study indicated that there were significant differences in average cost of care between home hospice sample and institutional care sample (t=9.956, p<.001; home hospice sample: M=18,102 won, institutional care sample: M=317,578 won). The cost of the home hospice sample was approximately 6% of the cost of institutional care. The majority of the home hospice nursing services were education (35.7%) and supportive counseling (25.2%), followed by medication management (13.6%), assessment (12.1%), basic nursing (7.2%), treatment (5.5%) and others. In institutional care sample, basic nursing and treatment were more emphasized than education or supportive counseling among the nursing services provided. The results of this study showed the potential for hospice to reduce costs and implications for policymakers and clinicians to incorporate hospice program into the formal health care delivery system in Korea.

Many telecommunication operators around the world have multiple networks. The networks run by each operator are always of different generations, such as 2G and 3G or even 4G systems. Each system has unique characters and specified requirements for optimal operation. It brings about resource allocation problem among these networks for the operator, because the budget of each operator is limited. However, the evaluation of resource allocation among various networks under each operator is missing for long, not to mention resource allocation optimization. The operators are dying for an algorithm to end their blind resource allocation, and the Resource Allocation Optimization Algorithm for Multi-network Operator (RAOAMO) proposed in this paper is what the operators want. RAOAMO evaluates and optimizes resource allocation in the view of overall cost for each operator. It outputs a resource distribution target and corresponding optimization suggestion. Evaluation results show that RAOAMO helps operator save overall cost in various cases.

Purpose: Hospice care represents all meaningful aspects of physical, mental and economical status of the end stage patients. The purpose of this study was to estimate the cost of home-based hospice care. Method: Fifteen nurses participated in counting an hour for requirement and home visit data of 50 end stage patients were analyzed. The method of to estimate the cost of home-based hospice care was three ways. Result: In case, including traffic expense, Singles fixed fee per visit via direct inquiry was 112,970 won but in case, excluding traffic expenses, was 86,036 won and traffic expenses per visit was 26,934 won. Final cost of home-based hospice care integrated the fixed fee per the needed time for visit and fee-for services. The fixed fee per 30 minutes was 35,251 won and 60 minutes was 46,595 won and 90 minutes was 57,939 won. We included pain management and the management of emergency and bereavement care among fee-for services. Conclusion: The cost of hospice care should be establish for not only patient but the living spouse, families, and children of the dying and for anyone else affected by any patient's death.

Purpose: This study reviewed what the location of death (LOD) means as an outcome and how to use LOD to assess end-of-life (EOL) care. This study also examined the reason why LOD is significant for the quality of EOL care. Methods: A literature review was performed, using LODs and home deaths as outcomes in the field of EOL care, and analyzed the findings associated with key fields in regards to LOD. Results: Palliative care research used LOD, in particular, hospital death (versus home death) as a significant outcome when examining cost savings, quality of life care, and patient and family preferences. Based on substantial evidence from previous research, home hospice or continuous palliative care in non-hospital settings (i.e. homes, nursing homes) have been designed and available for dying patients in developed countries. Conclusion: The LOD delivers practical significance as an outcome for diverse reasons. In-depth examination on LOD in South Korea is needed despite limitations to interpretation of its meaning in the country.

The purpose of this study is to analyze medical expenses by decedents in their last year of life and compare them with those by survivors during the year 2008. This study is conducted firstly in Korea, except some studies focusing on medical cost of decedents from specific diseases. To study this, national health insurance(NHI) claims data was used with medicaid claims data. The study group(decedents) was selected from the insurance entitlement file who were dropped out from January to December of 2008. The control group(survivors) was selected from the entitlement file by stratified sampling with keeping age-sex composition of the study group. The medical expenses of decedents during one year before death were measured and compared with those of survivors by sex and age. And the medical expenses were analyzed by causes of death, and also the expenses were examined by each item of medical services. On average, the medical expense amounted to 11 million Korean Won per decedent during their last year of life in 2008. The medical expense per decedent was 9.3 higher than that of survivor. The death-related expense of under the age 35 was about 16 million Won, compared with 4 million Won in the case of over the age 95, in average. The death-related expense is higher in younger ages. This means that more medical resources are put in to save life in younger ages. Total death-related expenditure took 8.3 percent in total NHI expenditures. Of the death-related medical expenses, the largest one was injection-related cost which shares twenty five percent, and the second largest one was hospitalization charges, and then the third one was surgery cost. The results of this study suggested that we should pay attention to the medical expenses in the last of year of life when we study health care expenditure in Korea. In addition, we have to deliberate health care policy to cope with medical expenditures before death in more efficient way.

Recently, attention for health promotion is rising. Alcohol is widely consumed among adults. About 1/3 of people 15 years of older enjoy drinking alcohol. Some 80% of them drink a half or more bottle of soju each time. Regular excessive drinking of alcohol may cause various problems. WHO(1990) reported that social problems such as divorce, unemployment, and financial difficulties ; psychological problems such as melancholy, suicide, and drug abuse ; physical problems such as cirrhosis, lung cancer, high blood pressure, stroke, and sterilization. The patients with liver disease are estimated to be 628,000. Approximately, 12,000 persons are dying by chronic liver disease and cirrhosis each year. Among the people of 15 years or older, persons dependent on alcohol are estimated to be 1,480,000. This study suggests policies to reduce the consumption of alcohol for planning for health promotion. Limitations of sites and times of sales and designation of sellers, designation of sites prohibiting drinking, limitation of alcohol sales promotion, and restrictions on advertisement can be inaugurated. Increase of price through the raise of tax and taxation of promotion cost. Education of high risk groups such as soldiers, pregnant women, and the youth can be introduced. Provision of alternative socialization programs instead of drinking. Some approaches on target groups were suggested.
