The objective of this paper is to estimate the causal effect of coresidence with an adult child on depressive symptoms among older widowed women in South Korea. Data from the first and second waves of the Korea Longitudinal Study of Aging were used. Analysis was restricted to widowed women aged ≥ 65 years with at least one living child (N=2,449). We use an instrumental variable approach that exploits the cultural setting where number of sons predicts the probability of an elderly woman's coresidence with an adult child but is not directly correlated with the mother's depressive symptoms. Our models adjust for age, education, total assets, residence, functional limitations, self-rated health, and various illnesses. Our robust estimation results indicate that, among older widowed women, coresidence with an adult child has a significant protective effect on depressive symptoms, but that this effect does not necessarily benefit those with clinically relevant depressive symptoms. Future demographic and social transitions in South Korea portend that older women’s increasing vulnerability to poor mental health is an important though less visible public health challenge.

Objective: To show the pattern of patient satisfaction with top-level delivery organizations (Level 2 and Level 3 hospitals), and using neo-institutionalism approach to explain the relatively low satisfaction and to explore the limitations with top providers, focusing on how to improve the competence of Level 2 and Level 3 hospitals at both the individual hospital level and the whole delivery system level.

Data Sources/Study Setting: The household survey by the National Bureau of Statistics in China in 2008; China Health Statistics Yearbooks.

Data Collection/Extraction Methods: The analysis uses a 2008 sample medical experiences of 5,036 residents from 17 provinces collected in a household survey by the National Bureau of Statistics in China. The linear regression model, the structural difference regression model, and the ordered probit model are used in our framework.

Principal Findings: The imbalance between the needs of patients and the limited competence of top-level providers, and the conflict between the business expansion and the limited competence of those providers are deeply and widely influenced by patterns of patient needs, the top providers’ expansion, and the institutional environment.

Conclusions: In order to effectively respond to patient needs, top and lower level providers need to set their own individual priorities. The government needs to improve institutional arrangements to respond to patient needs with the development of a fair and appropriate reimbursement and compensation pricing mechanism, and with further evaluation of top level providers’ advanced and limited health services.

Since 1978, China has been primarily market-focused in its provision of health care and social services. The market-driven health care system has been characterized by perverse incentives for individual providers, patients, and hospitals that are inducing improper provision of care: overprescription of pharmaceuticals and high-tech testing, lack of effective primary care and gatekeeping, and competition for patients instead of referral. The national health care reform document that was made public in April 2009 recognizes this failure of the market in health care in China. The document suggests potential policies for improvement on the current system that are focused primarily on a targeted increase in government funding and an increased, changing role for the government. We assess the potential of this national health care reform to achieve the stated goals, and conclude that the reform as designed is necessary but insufficient. For the reform to meet its goals, the promised increase in funding should be accompanied by improved data collection, regional piloting, and a strong regulatory and purchasing role for the government in aligning incentives for individual and institutional payers, providers, and patients.
