The purpose of this study is to measure the resource use of the elderly in long-term care services and to examine the effects of patient and facility characteristics on their use of resources. The data were collected from 510 old people over sixty years of age, residing in five long-term care hospitals and two skilled nursing homes during the period between December 1, 2000 and February 28, 2001. For a full sample, when the first level of RUG(Resource Use Group)-III categories were employed as the proxy of patient severity, facility characteristics, such as location, size and ownership, have large effects on the resource use measured by service intensity, whereas patient characteristics such as severity have little or no effect. The resource use is significantly high if the facility: (1) is located in rural areas (gun): (2) has mare than 200 beds; (3) is a long-term care hospital; (4) is private; and (5) has a low percentage of medical aid patients. The analysis of the resource use in each RUG-III categories, for which ADL(Ability of Daily Living) were employed as the prosy of patient severity, shows a similar result. The loose relationship between the needs of residents and the resource use seems to be closely associated with the ineffective reimbursement system for providers. The current reimbursement system has no provision for quality improvement and reimburses facilities simply according to their types: fee-for-service for long-term care hospitals, and monthly-flat-rate or full-coverage-national-aid for skilled nursing facilities. It will be necessary to develop a more reasonable reimbursement system that takes patient's severity into account and gives incentives for long-term care providers to offer cost-effective services.

Purpose: The purpose of this study was to identify the factors associated with the health-related quality of life of family caregivers. Methods: A cross-sectional study was conducted. This study included 191 primary family caregivers of elders who used home care services (home-visit nursing, home-visit care, daycare) covered by the public long-term care insurance. Data were collected using self-report questionnaires from December 2010 to June 2011. These data were analyzed by using hierarchical multiple regression. Results: The majority of the family caregivers were female (79.6%) and daughters-in-law (28.8%). The mean depression score was $6.33{\pm}6.49$ and the mean health-related quality of life score was $0.69{\pm}0.39$. It was found that the factors affecting the health-related quality of life of family caregivers included depression (${\beta}$=-.406, p<.001), home-visit nursing use (${\beta}$=.296, p<.001), and daycare use (${\beta}$=.178, p=.015), which accounted for 36.6% of their health-related quality of life. Conclusion: Using home-visit nursing and daycare services has a positive effect on the health-related quality of life of family caregivers. To improve health-related quality of life of family caregivers, South Korea needs to fully activate the home-visit nursing and daycare services, and to strengthen family support programs.

The objective of running a long-term care institution is to provide services helpful for maintaining, supporting, and improving elderlies' optimum level of physical, mental, and psychosocial functioning. For the purpose of analyzing the current situations of institutional long term care facilities in Korea, 27 facilities were selected proportionately from each of the cities and provinces, out of the total 152 facilities. About 20% of those who were institutionalized during 25 August through 2 Qctober 1993, the 391 elderlies were chosen on a systematic random basis. The instrument of this study was developed by modifying the tools of CARE, MAI and PCTC. A multivariate approach of discriminant analysis and clustering technique were employed for this study. The Stiudy reveals that there is no clear differentiation of goals and functions among the longterm care institutions in Korea. Staffing patte군 of long-term care facilities shows a shortage of nurses, physical therapists, and dieticians. The linkage between acute care facilities and long-term care is weak, and administration of long-term care faciltiy is carried out by non-professionals. They are responsible for assessing health status before entering the facility, and evaluating elderlies' care. Therefore, it is not surprising to find that most of the facilities have accommodated agede regardless of their real needs and health status. Based upon findings of the analysis, this study has classified long-term care facilities into four types : Type I is to help elderlies maintain independence in daily living activities. Type II facilities have the objective of maintaining and improving the current level of elderlies' function. Type III is to maintain maximum independence of elderlies in activities of daily living. And Type IV is identified for the group of facilities designed to restore or improve functional abilities of elderlies. In conclusion, the following suggestions are made : the need for long-term care should be assessed by multidimensional measurement. Institutional long-term care facilities should be classified and developed in response to type of type of care and service need. Both acute and long-term care facilities should be linked together in order to support the evaluation of service operation and program development.

Background: This study examined the relationships of dementia, stroke, and combined multimorbidity with long-term care utilizations among older people in South Korea. Methods: A nationally representative sample of 10,130 older adults who used long-term care services in 2010 were analyzed. We used the 5% sample of aged 65 years or older linked with National Health Insurance Corporation registry data of long-term care insurance system. The sample was categorized into three groups: dementia only (47.6%), stroke only (36.3%), and both dementia and stroke (16.1%). We estimated the use of institutional care, home care, and total expenditure of long-term care services, adjusting for the severity of each function (such as daily life, behavior or cognitive change, nursing care needs, and rehabilitation care needs) and sociodemographic characteristics. Results: Having dementia symptoms was positively associated with the use of institutional care services, on the other hand, having stroke symptoms was positively related with the use of home care. The total long-term care cost was higher in the group of having both dementia and stroke. Conclusion: Older persons with dementia symptoms and stroke symptoms have different patterns of long-term care utilization, and the multimorbidity increased the overall expenditure of long-term care utilization. These findings imply a need for differentiated management strategy targeting physically and cognitively impaired older persons, and special concerning for persons with multimorbidity conditions for long-term care insurance program in Korea.
