The purpose of this study is to provide preliminary data for political measures to minimize the variations by understanding the regional variations and trends of hospital services for heart diseases, and analyzing the factors that could occur any variations. The various data collected from nation-wide inpatient services conducted separately by small region show that there have been some differences in income level, supply of medical resources, standardized rate of hospitalization by sex and age, health level in the residence, and the length of stay per head. Then it indicated that the number of special medical equipment per 10,000 people and the rate of vigorous physical activity have the highest influence over the regional variations in using hospital services. On the other hand, the number of sick-beds per 10,000 people, the number of special medical equipment, and the present smoking rate have significant degree of influence on the length of stay per head. Thus, it is imperative for the authorities to set aside health promoting policies and to distribute the medical resources equitably throughout the country and to enhance the accessibility of local residents to the health care services.

This study aims to develop the severity-adjusted length of stay(LOS) model for acute stroke patients using data from the hospital discharge survey and propose management of length of stay(LOS) for acute stroke patients and using for Hospital management. The dataset was taken from 23,134 database of the hospital discharge survey from 2004 to 2009. The severity-adjusted LOS model for the acute stroke patients was developed by data mining analysis. From decision making tree model, the main reasons for LOS of acute stroke patients were acute stroke type. The difference between severity-adjusted LOS from the decision making tree model and real LOS was compared and it was confirmed that insurance type and bed number of hospital, location of hospital were statistically associated with LOS. And to conclude, hospitals should manage the LOS of acute stroke patients applying it into the medical information system.

Objective: The objective of this study is to examine the association between process quality of inpatient care and risk-adjusted, thirty-day potentially preventable hospital readmission (PPR) rates. Data Sources/Study Setting: This was an observational cross-sectional study of nonfederal acute-care hospitals located in two states California and Florida, discharging Medicare patients with a principal discharge diagnosis of heart failure, acute myocardial infarction, or pneumonia January through December 31, 2007. Data were obtained from the Healthcare Cost and Utilization Project State Inpatient Database of the Agency for Healthcare Research and Quality, Centers for Medicare and Medicaid Services Hospital Compare database, and the American Hospital Association Annual Survey of Hospitals. Study Design: The dependent variable of this study is condition-specific, risk-adjusted, thirty-day potentially preventable hospital readmission (PPR). 3M's PPR software was utilized to determine whether a readmission was potentially preventable. The independent variable of this study is hospital performance for process quality of inpatient care, measured by hospital adherence to recommended processes of care. We used multivariate hierarchical logistic models, clustered by hospitals, to examine the relationship between condition-specific, risk-adjusted, thirty-day PPR rates and process quality of inpatient care, after taking clinical and socio-demographic characteristics of patients and structural and operational characteristics of hospitals into account. Findings: Better performance on the process quality metrics was associated with better patient outcome (i.e., low thirty-day PPR rates) in pneumonia, but not generally in two cardiovascular conditions (i.e., heart failure and acute myocardial infarction). Practical Implication: Adherence to the process quality metrics currently in use by CMS is associated with risk-adjusted, thirty-day PPR rates for patients with pneumonia, but not with cardiovascular conditions. More evidence-based process quality metrics closely linked to 30-day PPR rates, particularly for cardiovascular conditions, need to be developed to serve as a guideline to reduce potentially preventable readmissions.

This study aimed to elucidate the differences in nursing service experience according to the participants' characteristics and experience of hospitalization and to identify the relation between nursing service experience and perceptions of the health system. It analyzed the data from a "Survey of health care service experience" conducted among 574 participants who had been hospitalized. The results showed that the mean nursing service experience of participants who had never used other hospitals before hospitalization with over ten days of hospital stay was higher compared with the other participants. Moreover, those who used other hospitals before hospitalization reported lower nursing service experience scores. In the classification based on the change of the inpatient room, the difference in the nurse service experience according to the number of hospitalization days was significant only in patients who had no change in the inpatient room in the multi-person room. The nursing service experience scores were positively related to general satisfaction with the hospitalization experience, health system satisfaction, and trust in the health system. This finding implies that the nursing service experience should be interpreted by separating the inpatient experience, and the strategies to improve the nursing service are needed. In addition, the survey should include items related to the characteristics of medical institutions such as nurse staffing, to identify factors affecting the experience of nursing services.

Purpose: The purpose of this study was to evaluate hospital service utilization by the types of hospitals in Type I Medicaid claims frequently cited by elderly beneficiaries. Methods: Three frequently claimed inpatient diseases were selected: cerebral infarction, hypertension and diabetes mellitus. Relevant data were collected for the year 2008 from the computer database of the National Health Insurance Corporation. The data was analyzed using SPSS by descriptive statistics, ANOVA and coefficient of variation. Results: The coefficient of variance of hospitalization per episode was higher than daily hospital expenditure among hospitals for all three diseases. The coefficient of variance of hospitalization per episode was highest for cerebral infarction. The coefficient of variation of hospital expenditure per hospital day was highest for hypertension. Conclusions: Evaluating of the volume and pattern of hospital service utilization and the appropriateness for hospital admission for Type-I Medicaid elderly beneficiaries is important for Medicaid-based case management.

The purpose of this study is to identify the relationship between health insurance and health by evaluating the impacts of health insurance coverage expansion on health care utilization and health status. To analyze the causal relationship between health insurance and health, this study employed a "difference-in-difference method" that could compare changes in health care utilization and health status across groups in health insurance coverage expansion in 2005. The researcher predicted that the expansion of health insurance coverage would be an exogenous source of variation in the prices of health service use. First, the difference-in-differences estimator between 'illness group' and 'non-illness group' revealed that the increase in coverage of inpatient care services would result from the increases in the stay of length of 'non-illness group' rather than that of 'illness group'. However, the difference-in-differences estimator between 'serious illness group' and 'chronic illness group' identified that the policy change that focuses on expansion of the coverage for 'serious illness' effects on the increases in health care utilization and promotion of health status. In summary, the changes of health insurance coverage focusing on serious illness and inpatient care have positive effects on health care utilization and health status of serious illness group. But, 'non-illness groups' with acute illness receive more benefits from the policy change than 'illness group' with chronic illness.

The study was carried out to identify the relationship of patients' self-rating and nurses' rating on health literacy of hospitalized patients. Data were collected using the Korean Functional Health Literacy Test (KFHLT) which was revised for hospitalized patients and Single Item Literacy Screener. A total of 178 subjects, which consisted of 89 hospitalized patients and 89 nurses taking care of them, were recruited from medical and surgical wards of E university hospital. Collected data were analyzed using SPSS 23.0 program. The results showed that the average health literacy score of the subjects was $11.45{\pm}4.22$ out of 17 and the average correct answer rate was 67.3%. Patient health literacy was significantly different by age, education, occupation and reading handouts. The patients' self-rating had significant correlation with health literacy measured by KFHLT while nurses' rating did not. There was no significant correlation between patients' self-rating and nurses' rating. The findings suggest that patients' self-rating might be available to assess patient health literacy in hospitals and a careful approach is required when nurses use a single-item rating.

The purpose of this study was to examine the effects of the stress on depression of elderly inpatients in geriatric hospitals and verify the mediating effects of self-esteem on the relationships between stress and depression. Data collected from 218 elderly inpatients of geriatric hospitals in Seoul and Gyeonggi region from Sept. 4th to 22nd, 2017 were analyzed with SPSS 23.0. As a results, there was a statistically significant difference in the level of stress, depression, self-esteem of elderly inpatients in geriatric hospitals depending on their Socio-demographic and Hospital-utilization characteristics. Stress of elderly inpatients had a positive influence on their depression(${\beta}=.297$, p=.000), the self-esteem had a partial mediating effect on the relationships between stress and depression(Sobel Z=2.034). These results suggest that the development and provision of self-esteem improvement programs as well as stress management of elderly inpatients are necessary to prevent depression of elderly inpatients in geriatric hospital.
