Several common issues are encountered by countries - Germany, Japan, and the United States - that adopted long-term care (LTC) system. First, the demand for LTC and its associated costs have steeply risen following the implementation of the LTC policy. Second, ensuring the quality of services have been difficult. Third, the coordination of services among providers and between LTC and medical care has been inadequate. Learning from their experience, we suggest ways to improve the LTC system in Korea. The basic approach aims for efficiency over equity in the system. This would require promoting provider competition and consumer choice. We propose several policy options according to the major stakeholders. For consumers, cash benefits at fixed rates and personal savings accounts are feasible options to self-contain the demand and cost of services. On the insurer's side, creating an environment of multiple insurers will engender competition, leading to cost savings and quality care. For providers, delivery of quality services through competition, cost-containment through capitated reimbursements, and coordination of services through integrated delivery system can be achieved. From the assessors' perspective, establishing an information system to monitor the activities of insurers and providers would be important, empowering consumers with information to choose cost-effective service providers. In summary, the suggested approach would provide cost-effective LTC services by guaranteeing consumer choice and promoting major stakeholder accountability. Further studies are needed to test the feasibility of this model in ensuring quality LTC in Korea.

Background: The objective of this study was to explore patient family's evaluation of emergency department (ED) service satisfaction and to compare these with ED staff perception of patient family's evaluation. Methods: Based on two surveys of the National Emergency Medical Center: the 2008 National Survey for Recognition and Satisfaction towards Emergency Medical Services and the 2008 Opinion Survey of Emergency Medical Service Providers, satisfaction gaps among physicians, nurses, and patient family were evaluated by Kruskal-Wallis tests and Wilcoxon-Mann-Whitney tests. Furthermore, the factors associated with satisfaction of emergency medical service were identified by ordinal logistic regression models. Results: There were statistically significant gaps among physicians, nurses, and patient family in overall satisfaction with ED visit, length of stay in ED, enough explanation, physicians/nurses kindness, and ED facilities. Age and income in the patient family model, the number of beds in hospital, job satisfaction and year of service in the physicians model, and the number of beds in hospital, job satisfaction and the number of patients per duty hour in the nurses model were statistically significant factors associated with evaluation/ perception of ED service satisfaction. Conclusion: Patient satisfaction is an important indicator of the quality of care and service delivery in the ED. To improve and understand satisfaction in ED service, a dyadic view of the evaluation of service quality and satisfaction-that is, from the perspectives of both the patient and the emergency medical service providers-should be concerned.

This study was conducted to develop a construct model regarding the daily activities, emotional security provided by food, enjoyment of food, level of satisfaction with delivered food, and the quality of life of homebound seniors who benefitted from meal delivery programs. The data were analyzed by SAS 9.2 and the Structural Equation Model (SEM), which was created by Analysis of Moment Structure (AMOS) 5.0 packages. The reliability of the data was confirmed by an exploratory factor analysis and through a Cronbach's alpha coefficient, and the measurement model proved to be appropriate by a confirmatory factor analysis of the measurement model in conjunction with AMOS. The results of the correlations between all the variables showed significant positive correlations (P < 0.05). The path analysis demonstrated that the daily activities (P < 0.01) and the emotional security created by food (P < 0.05) had positive correlations with the foodservice satisfaction (P < 0.05), while the daily activities (P < 0.05), the sense of emotional security made by food (P < 0.05), and food enjoyment (P < 0.05) also presented significant positive correlations with the quality of life. However, the food service satisfaction was shown to directly, but not significantly, affect the quality of life. This revealed that the current meal delivery programs needed to be improved in several directions.

The study was aimed at developing an independent hospice center model that would be best suited for Korea based on a literature review and the current status of local and international hospices. For the study, five local and six international hospice organizations were surveyed. Components of the hospice center model include philosophy, purpose, resources (workers, facilities, and equipment), allocation of resources, management, financial support and hospice team service. The following is a summary of the developed model: Philosophies for the hospice center were set as follows: based on the dignity of human life and humanism, help patients spend the rest of their days in a meaningful way and accept life positively. On the staff side, to pursue a team-oriented holistic approach to improve comfort and quality of life for terminally ill persons and their families. The hospice center should have 20 beds with single, two, and four bed rooms. The center should employ, either on a part-time or full-time basis, a center director, nurses, doctors, chaplains, social workers, pharmacists, dieticians, therapists, and volunteers. In addition, it will need an administrative staff, facility managers and nurses aides. The hospice should also be equipped with facilities for patients, their families, and team members, furnished with equipment and goods at the same level of a hospital. represented by a center director who reports to a board and an advisory committee. Also, the center director administers a steering committee and five departments, namely, Administration, Nursing Service, Social Welfare, Religious Services, and Medical Service. Furthermore, the center should be able to utilize a direct and support delivery systems. The direct delivery system allows the hospice center to receive requests from, or transfer patients to, hospitals, clinics, other hospice organizations (by type), public health centers, religious organizations, social welfare organizations, patients, and their guardians. On the other hand, the support delivery system provides a link to outside facilities of various medical suppliers. In terms of management, details were made with regards to personnel management, records, infection control, safety, supplies and quality management. For financial support, some form of medical insurance coverage for hospice services, ways to promote a donation system and fund raising were examined. Hospice team service to be provided by the hospice center was categorized into assessment, physical care, emotional care, spiritual care, bereavement service, medication, education and demonstrations, medical supplies rental, request service, volunteer service, and respite service. Based on the results, the study has drawn up the following suggestions: 1. The proposed model for a hospice center as presented in the study needs to be tested with a pilot project. 2. Studies on criteria for legal approval and license for a hospice center need to be conducted to develop policies. 3. Studies on developing a hospice charge system and hospice standards that meet local conditions in Korea need to be conducted.
