Objectives

The purpose of this study was to classify determinants of cost increases into two categories, negotiable factors and non-negotiable factors, in order to identify the determinants of health care expenditure increases and to clarify the contribution of associated factors selected based on a literature review.

Methods

The data in this analysis was from the statistical yearbooks of National Health Insurance Service, the Economic Index from Statistics Korea and regional statistical yearbooks. The unit of analysis was the annual growth rate of variables of 16 cities and provinces from 2003 to 2010. First, multiple regression was used to identify the determinants of health care expenditures. We then used hierarchical multiple regression to calculate the contribution of associated factors. The changes of coefficients (R2) of predictors, which were entered into this analysis step by step based on the empirical evidence of the investigator could explain the contribution of predictors to increased medical cost.

Results

Health spending was mainly associated with the proportion of the elderly population, but the Medicare Economic Index (MEI) showed an inverse association. The contribution of predictors was as follows: the proportion of elderly in the population (22.4%), gross domestic product (GDP) per capita (4.5%), MEI (-12%), and other predictors (less than 1%).

Conclusions

As Baby Boomers enter retirement, an increasing proportion of the population aged 65 and over and the GDP will continue to increase, thus accelerating the inflation of health care expenditures and precipitating a crisis in the health insurance system. Policy makers should consider providing comprehensive health services by an accountable care organization to achieve cost savings while ensuring high-quality care.

OBJECTIVES
Organizational culture has been important in field of organizational behavior research for the past decade. Although there has been a growing interest in the organizational culture and organizational effectiveness, there is few research in health care field. This study was carried out to investigate the relationship of organizational culture and organizational effectiveness at general hospital. METHODS: Data was collected by self-administrated questionares. Organizational cultures were measured by using Likert scale. A general hospital in Kyunggi-Do was selected and survey was conducted to 675 workers. Data was analyzed with computer package, PC- SPSS. RESULTS: There were four types of organizational culture in this hospital : consensual culture, developmental culture, hierarchical culture, rational culture. Many workers recognized their culture as rational culture and developmental culture. This finding showed that the hospital had both human related and task related climate. There were some differences in recognition of sub-organizational culture by occupational group, but perceived organizational culture was in accordance with sub-organizational culture in general. Multiple regression analysis and multiple logistic regression analysis were conducted to find the relationship of organizational culture and organizational effectiveness. As a result, developmental culture showed a strong relationship with organizational commitment and job-satisfaction. CONCLUSIONS: These results showed that types of organizational culture were significantly related to organizational effectiveness and understanding the existing culture is essential to develope their organizational effectiveness.
