This study relates to the problems of organizational performance in the Christian hospitals. In this study, quality of working life (QOWL), which harmonizes individual as well as organizational goals, was used as an indicator of organizational performance from the open systems view. In order to identify the behavioral factors influencing QOWL in hospitals, self-administered questionnaires were distributed to 1,926 employees who were randomly selected from fifteen Christian hospitals from August 1 to August 30, 1986. The following results were obtained: 1) All correlation coefficients between QOWL and behavioral variables were statistically significant even though their magnitude varied according to hospital size. 2) Using factor analysis, 32 variables were parsimoniously grouped into four factors: individual conflicts, group behavior, organizational characteristics and situation, and job characteristics. The proportion of variance explained by these factors ranged from 33.5% to 38.6% according to hospital size. 3) The overall effects of the four factors in the multiple logistic models ranged from 0.85 to 3.12 according to hospital size. Among three hospital models, the model for small hospitals showed the best statistical fit. 4) The most influential factor was organizational characteristics and situation with an odds ratio ranging from 1.99 to 3.02. Again, the odds ratio was the highest for small hospitals. 5) For large hospitals, the two main factor effects were statistically significant: organizational characteristics and situation, and job characteristics. For medium hospitals, all main factor effects except job characteristics were statistically significant. For small hospitals, all main factor effects except group behavior were statistically significant. However, a factor interaction effect was shown only for large hospitals where it was statistically significant. 6) To examine whether the four factors influence financial performance, the four factor scores from the two financial performance groups were compared using Mann-Whitney test. The test results showed that the organizational characteristics and situation factor score was significantly different only for small hospitals.

This study analyzed whether the patients' visits to oriental medicine hospitals were influenced by the Euclidean distance from patients' residence to oriental medicine hospitals. Patient who visited two oriental medicine hospitals in a metropolitan area were selected for study sample. The number of patient from each Dong (which is the smallest administrative district) to two hospitals was calculated based on claims data in 2008. ArcGIS was used to calculate the distance. Distance variable was not statistically significant in regression analysis after controlling the difference of socio-economic status of people in each Dong. It seems that distance factor did not play an important role in deciding whether to use the services of oriental medicine hospitals in a metropolitan area.

The purpose of this study is to compare the measurement result of radiation dose by using standard thoracic phantom and ionization chamber to advice proposal in the shooting condition of chest PA projection at hospitals recently. And to understand the change between radiation dose and resolution in different conditions. The period this study was from August 2010 to September 2010 and the subjects of the study was 3 general hospitals, 4 personal hospitals and 1 laboratory at the college. Finally we study with 6 DR, 1 CR, and 4 F/S equipments. Most hospitals met advice proposal, but some of the hospitals exceed advice dose from the result of our study. We can lower radiation dose about 25% when kVp is lowered about 20% in DR equipment. And we can lower radiation dose about 50% when mAs is lowered about 35%. The image quality was similar to the original in the study. Most hospitals which exceed advice dose were personal hospitals. The reason why it happened is that radiation dose for chest PA projection at personal hospitals is higher than general hospitals and the personal hospitals' equipments are older than general hospitals' equipments. We guess that patients' radiation dose of chest PA projection can be lowered from the result.

This study evaluated the specialization status of Korean hospitals by applying index measures that were developed to determine how hospitals are specialized. In addition, multivariate regression analysis was applied to assess how the measures responded to the internal and external factors of hospitals. National Health Insurance claims for 2004 were used to calculate the information theory index, internal Herfindahl index, number of distinct diagnosis-related groups (DRGs) treated, and percent of the five most common DRGs. Data from the Ministry of Health and Welfare and Korean Hospital Association were used to determine the size, ownership, teaching status, organization type, and location of the hospitals. The four indexes analyzed showed that there were significant differences in the specialization status of providers, depending on the provider size, organization type, and location. Hospitals that were smaller and located in metropolitan areas tended to provide specialized services; this is considered to constitute a competitive strategy for hospitals. It is expected that specialized hospitals will increase given the current market structure. Therefore, policy makers will need an index for measuring how hospital services are specialized. Information from such an index could provide a picture of how hospital services are mixed and change over time.

BACKGROUND/OBJECTIVES: The prevalence of malnutrition among hospitalized children ranges between 12% and 24%. Although the consequences of hospital malnutrition are enormous, it is often unrecognized and untreated. The aim of this study was to identify the current status of in-hospital nutrition support for children in South Korea by carrying out a nationwide hospital-based survey. SUBJECTS/METHODS: Out of 345 general and tertiary hospitals in South Korea, a total of 53 institutes with pediatric gastroenterologists and more than 10 pediatric inpatients were selected. A questionnaire was developed by the nutrition committee of the Korean Society of Pediatric Gastroenterology, Hepatology and Nutrition. The questionnaires were sent to pediatric gastroenterologists in each hospital. Survey was performed by e-mails. RESULTS: Forty hospitals (75.5%) responded to the survey; 23 of them were tertiary hospitals, and 17 of them were general hospitals. Only 21 hospitals (52.5%) had all the required nutritional support personnel (including pediatrician, nutritionist, pharmacist, and nurse) assigned to pediatric patients. Routine nutritional screening was performed in 22 (55.0%) hospitals on admission, which was lower than that in adult patients (65.8%). Nutritional screening tools varied among hospitals; 33 of 40 (82.5%) hospitals used their own screening tools. The most frequently used nutritional assessment parameters were weight, height, hemoglobin, and serum albumin levels. In our nationwide hospital-based survey, the most frequently reported main barriers of nutritional support in hospitals were lack of manpower and excessive workload, followed by insufficient knowledge and experience. CONCLUSIONS: Although this nationwide hospital-based survey targeted general and tertiary hospitals with pediatric gastroenterologists, manpower and medical resources for nutritional support were still insufficient for hospitalized children, and nutritional screening was not routinely performed in many hospitals. More attention to hospital malnutrition and additional national policies for nutritional support in hospitals are required to ensure appropriate nutritional management of hospitalized pediatric patients.

Purpose: To report on the current practices in breast magnetic resonance imaging (MRI) in Korea. Materials and Methods: We invited the 68 members of the Korean Society of Breast Imaging who were working in hospitals with available breast MRI to participate in a survey on how they performed and interpreted breast MRI. We asked one member from each hospital to respond to the survey. A total of 22 surveys from 22 hospitals were analyzed. Results: Out of 22 hospitals, 13 (59.1%) performed at least 300 breast MRI examinations per year, and 5 out of 22 (22.7%) performed > 1200 per year. Out of 31 machines, 14 (45.2%) machines were 1.5-T scanners and 17 (54.8%) were 3.0-T scanners. All hospitals did contrast-enhanced breast MRI. Full-time breast radiologists supervised the performance and interpreted breast MRI in 19 of 22 (86.4%) of hospitals. All hospitals used BI-RADS for MRI interpretation. For computer-aided detection (CAD), 13 (59.1%) hospitals sometimes or always use it and 9 (40.9%) hospitals did not use CAD. Two (9.1%) and twelve (54.5%) hospitals never and rarely interpreted breast MRI without correlating the mammography or ultrasound, respectively. The majority of respondents rarely (13/21, 61.9%) or never (5/21, 23.8%) interpreted breast MRI performed at an outside facility. Of the hospitals performing contrast-enhanced examinations, 15 of 22 (68.2%) did not perform MRI-guided interventional procedures. Conclusion: Breast MRI is extensively performed in Korea. The indication and practical patterns are diverse. The information from this survey would provide the basis for the development of Korean breast MRI practice guidelines.

Objective: This study aimed to introduce cases of exposure to humidifier disinfectant (HD) in hospitals and to present their exposure characteristics. Methods: We used data from 4,393 subjects who participated in the fourth assessment survey of environmental exposure to HD conducted by the Korea Environmental Industry & Technology Institute. In this study, we selected 301 subjects who reported their place of use of HD as a hospital. Then, we classified cases as 'Hospital-provided'. 'Probably hospital-provided', 'Individual purchased', and 'Unknown' according to the supply sources of HD. Also, we introduced detailed exposure characteristics for the selected cases. Results: Of the 4,393 subjects, 301 (6.9%) reported the use of HD in 392 hospitals (including duplicate answers for the use in ${\geq}2$ hospitals). The 301 hospital-user subjects included 139 survivors and 162 non-survivors. When we classified the 392 cases by supply sources, 'Hospital-provided' was 12.2% (48 cases), 'Probably hospital-provided' was 25.5% (100 cases), 'Individual purchased' was 59.7% (234 cases), and 'Unknown' was 2.6% (10 cases). Among the 'Hospital-provided' cases, we selected six cases and provided a detailed description of the HD use in this study. Additionally, we reported details for six cases that had purchased HD upon a doctor or nurse's recommendation and for three cases that had purchased it at hospital stores. Conclusion: This study presents various cases of HD exposure in hospitals. Because there may be a considerable burden of HD exposure in public spaces, including hospitals, further studies are necessary to assess HD exposure in hospitals and public places.

The purpose of this study was to investigate the awareness of long-term care hospitals on pay for performance(P4P) program in Korea. We conducted a cross-sectional, self-administered, the internet based survey from September to October in 2010. The questionnaire was consisted of the levels of awareness and agreement about the program, their preferred design and its possible effects and unintended consequences etc. Among 837 eligible long-term care hospitals in Korea, 114 hospitals(13.6%) were participated in the survey. About one-thirds of long-term care hospitals were not aware of P4P, namely it is important to heighten an awareness of P4P. There were pros and cons on introduction of P4P in Korea. The two major reasons of objections of P4P were the concerns of unintended consequences and the possibility of strengthening government control by implementing P4P. In conclusion, to successfully implement P4P to long-term care hospitals, the Health Insurance Review & Assessment Service(HIRA) in Korea should obtain the long-term care hospitals'opinion as to implementation of P4P.

Objectives : Vascular dementia is the second common cause of dementia after Alzheimer's disease. It assumed that the ratio of prescription drugs on vascular dementia are quite different from each hospital in Western medicine or Oriental medicine, respectively. The aim of this research is to collect and analyze the ratio of prescription drugs on vascular dementia in Western medicine or Oriental medicine in university hospitals. Methods : We collected and analyzed the data related to prescriptions on vascular dementia in the department of neurology in three university hospitals(A, B, C) and in the department of internal medicine in two Oriental medicine hospitals(Daegu Haany Oriental Hospital, Dong Eui Oriental Hospital). Results : In the department of neurology in A university hospital, donepezil(69.1%), memantine(14.0%), rivastigmine(12.3%), galantamine(4.5%) were prescribed in order. In B university hospital, galantamine(57.8%) donepezil(33.3%), rivastigmine(6.7%), donepezil with memantine(4.4%) were prescribed. In C university hospital, donepezil(62.0%), rivastigmine(25.0%), galantamine(7.0%) memantine(6.0%) were prescribed. The average frequencies of prescribed medication in the department of neurology in A, B, C university hospitals were donepezil(54.8%), galantamine(23.1%), rivastigmine(14.7%), memantine(7.4%). In Oriental medicine hospitals, various prescriptions have been used for vascular dementia. Among them, Ansincheongnoetang (安神淸腦湯) and Gamijihangeumja(加味地黃飮子) were often prescribed in Daegu Haany Oriental Hospital, and Bojungikgitang(補中益氣湯) in Dong Eui Oriental Hospital, too. Conclusions : Cholinesterase inhibitors such as donepezil, galantamine, rivastigmine and NMDA receptor inhibitor like memantine have been used as a drug of choice for vascular dementia in all surveyed university hospitals. In oriental hospitals, various prescriptions have been used for vascular dementia.

Objective: This study aimed to introduce the use of humidifier disinfectant (HD) in hospitals based on an on-site investigation. Methods: A preliminary survey and on-site investigation of HD use were conducted in 23 hospitals. Among them, one hospital without previous information on HD use was selected for a pilot investigation; 22 hospitals were selected based on previous documents and exposure statements from parliamentary investigation and exposure assessment regarding HD. Descriptive statistics were used to present distribution and characteristics of HD purchase and HD use in hospitals. Also, details on interviews from the on-site investigation were described. Results: Among the 23 hospitals, a total of ten were confirmed to have purchased and used an HD (nine hospitals) or HD-like product (one hospital). For the purchased HD products, four hospitals reported 'Aekyung Gaseupgi Mate', two hospitals reported 'Oxy Ssakssak New Gaseupgi Dangbun', and one hospital reported 'Homeplus Gaseupgi Chungjungje' (one hospital used three kinds of HD products). One hospital reported an HD-like product and four hospitals were 'Unknown'. For the number of HD products purchased, five hospitals reported '100 or less', two hospitals reported 'More than 100', and three hospitals were 'Unknown'. For each of the ten hospitals, we described detailed characteristics of HD purchase and its exposure status obtained through on-site investigation, including the purchase volume (i.e., number of products), exposure space (i.e., patient's room, staff space), and exposure period. Additionally, a comparison of on-site investigation and parliamentary investigation or exposure assessment regarding HD was reported. Conclusion: This study introduced detailed cases of HD purchase and HD use in hospitals based on an on-site investigation, and our findings revealed a possibility of a considerable volume of HD exposure in various multiuse facilities, including hospitals.
