There are increasing interest and need for information on health care consumer with the significance of hospital marketing and strategic planning being increasingly emphasized. This study was conducted to investigate the criteria for selection of medical facilities according to the characteristics of health care consumer by the types of medical services on a sample of 1,500 population aged 20 years and above. Major findings are as follows; 1. When considering the criteria for selection of medical facilities into two factors, namely, quality or convenience factors, convenience factor was the major contributor for outpatient and dental services whereas it was quality factor for inpatient services. 2. Females and those residing in large cities selected medical facilities based on convenience factor in the outpatient services. In the case of inpatient service, persons who considered their present health status to be good and whose ages were 50 years old and above choose medical facilities based on quality factor. 3. Persons who considered medical facilities to be profit-making tended to choose medical facilities based on convenience factor for outpatient services. There were no differences in the cases of inpatient and dental services. 4. There was no significant difference on the criteria for selection of medical facilities according to the decision maker for selection or trust on medical facilities. On the use of health service information, selection of medical facilities was based on qPality factor for those who made more use of the information in the cases of outpatient and dental services. 5. Analysis using the logistic regression model on the criteria for the selection of medical facilities with the characteristics of health care consumer as independent variables was performed. The selection of medical facilities was significantly related with residential area, sex, and use of information on medical facilities for outpatient services and with age, average monthly income, and perception of health status for inpatient services. For dental services significant association with residential area and use of information on medical facilities was seen. The results of this study, despite some limitations, can be used as baseline data for marketing and strategic planning of hospital management.

Service diversification is recognized as an important strategy against turbulent environmental change. This study is designed to find out the trend of service diversification in Korean health care organizations and also to identify factors associated with the degree of service diversification. Data were collected from 69 hospitals out of 71 hospitals with over 300 beds. Important findings are summarized below. 1. Types of diversification are closely related to hospital size. Large hospitals have a tendency to provide sophisticated service requiring specialized skills and equipment, while small hospital have concentrated their efforts on health screening programs. 2. The more competitive and bigger hospitals are, the greater number of services that provide. Also, hospitals operating rational management information systems provide more services. Contrary to the expectation, hospitals with a low performance during last 3 years showed more service diversification. 3. A trend of more diversification was observed in hospitals whose chief executive officer used a prospector strategy. 4. A multiple regression analysis revealed that bed size, competitive environment, degree of rational management, and the growth pattern were significantly associated with teh service diversification.

Pulmonary vascular hypertension is characterized by migration and proliferation of smooth muscle cells accompanying abnormal synthesis and accumulation of extracellular proteins in vascular wall. The aim of this study is to define the role of endogneous TGF-betas and PDGF in the process of remodeling vessels through determining the temporal and spatial distribution of these growth factors in hypertensive pulmonary vessels in monocrotaline-induced pulmonary hypertension in rat. Sprague-Dawley rats were sacrificed 12 hours, 1, 2, 4, 7, 10, 14, 21, 28, and 56 days after treatment. The morphometric analysis of medial thickening and immunohistochemical study using antibodies to TGF-beta1, TGF-beta2, TGF-beta3, and PDGF were performed. Immunoreactivities for TGF-beta1 and TGF-beta3 were increased from the 14th day in the medial smooth muscle cells and PDGF showed increased expression from the 21st day in the medial smooth muscle cells. No difference in TGF-beta2 immunoreactivity was found between control and experimental groups. The expression of TGF-beta1, TGF-beta3 and PDGF increased in medial layers with the progressive thickening of pulmonary arteries which was considered to have close relation to medial hypertrophy of pulmonary arterioles. In the case of PDGF, however, the morphologic change occurred before increase in immunoreactivity was observed in the medial layer of pulmonary arterioles. Moreover, the function of isoforms of TGF-beta has yet to be completely elucidated; the different affinity to receptors and the degree of expression of these receptors that are supposed to affect the function of growth factors. Thus, further studies are needed.

This study was designed to investigate factors relating to fiscal deficit for regional health insurance. The financial statements for the fiscal year 1990 of nationwide 254 regional medical insurance societies were analyzed. Important findings are summarized below: 1. There were differences in the main reason for the financial deficit among regions when deficit and surplus societies were compared by regions. The total revenue per enrollee, especially revenue from the premium contribution of a deficit society was significantly smaller than that of a surplus society in large cities and counties. On the other hand, the total expenditure per enrollee of a deficit society was larger than that of a surplus society in small cities. 2. Both low premium irate at the beginning of health insurance program and less effort to increase the premium rate were main factors for the smaller revenue from the contribution of a deficit society in large cities and counties. 3. Larger expenditures per covered person of a deficit society in small cities were explained with larger medical expenditures especially for out-patients services rather than larger administrative expenses. 4. A regression analysis showed that utilization rates in out-patient services were significantly associated with income and numbers of total medical care institution per capita within a region where a health insurance society located. Also expenses paid by insurer per visit were associated with the proportion of utilization for tertiary care hospitals as well as the proportion of utilization of public health centers.

PURPOSE: The aim of this study is to investigate the colonization rate of Methicillin-resistant Staphylococcus aureus (MRSA) in neonates by different clinical characteristics, to presume the origin of MRSA acquisition, and to identify the risk factors associated with MRSA colonization. METHODS: We retrospectively reviewed the medical records of 1,733 neonates admitted to Seoul Eulji hospital Neonatal Intensive Care Unit between January 2008 and December 2011. Nasal, inguinal and rectal swab specimens were obtained upon admission and each week until discharge. We classified the route of MRSA acquisition as; hospital associated (HA-MRSA) and community associated (CA-MRSA) according to the case definition. RESULTS: Among 1,733 neonates, 415 (23.9%) were colonized with MRSA. Gestational age, birth weight, delivery type, maternal antibiotics usage before delivery, birth place and care place before admission were influencing factors in colonization of MRSA. The colonization rate was significantly high in neonates without maternal prophylactic antibiotics use before delivery than in the other group (relative risk 2.77, 95% CI 1.88-4.07; P<0.01), and outborns showed higher MRSA colonization rate compared to inborns (relative risk 2.28, 95% CI 1.17-4.42; P=0.015). CONCLUSION: We identified the neonatal MRSA colonization rate to be 23.9%. We estimated HA-MRSA colonization rate to be 10% (51/511) and CA-MRSA colonization rate to be 36% (309/858). We ascertained that risk factors in MRSA colonization in neonates were prophylactic use of antibiotics in mothers and the birth place.

PURPOSE: Pediatric sedation is an important factor for obtaining the images of good quality. We performed this study to analyze the efficacy of our sedation protocol using chloral hydrate. MATERIALS AND METHODS: We collected prospectively 151 sedation records of children(1 day-15 years old), who were sedated with chloral hydrate for MR(n=112) or CT(n=39) studies. We initially administered 50mg/Kg orally(n=94) or rectally(n=57) 30 minutes before the scheduled examinations, and then administered additionali dose (second dose :25-35mg/Kg, third dose:10-15mg/Kg) to patients whom initial dose failed to sedate. RESULTS: Satisfactory sedation was achieved by initial administration in 109 patients(72%) without si difference between oral(per oral: P.O.) and rectal(per rectal: P.R.) administration. Second dose was required in 28% and third dose in 5%. MR and CT examinations required second dose in 36(32%) and 6 patients(15%), respectively. P.O. -patients vomited in 5%. P.R. -patients defecated in 22% after initial administration. There were no other serious complications. Time interval from the drug administration to the start of examinations was 33 minutes in initial-dose-group and 64 minutes in additional-dose-group. Two patients could not complete MR examination due to early arousal. Prolonged sedation, requiring more than 30 minutes for alertness after MR and CT examinations, was encountered in twenty(18%) and two patients(5%), respectively. CONCLUSION: Our protocol using chloral hydrate(P.O. or P.R.) is thought to be an effective and safe method for pediatric sedation for MR or CT imaging.

9.Relation between Health Habits and Stree in Adolescents.
Journal of the Korean Academy of Family Medicine 1999;20(10):1247-1254
BACKGROUND: Adolesoents experience many physical, psychological and social stresses. It is well known that there is a strong relationship between stress and illness. It has been told that good health goes with good health habits. We examine the relationship between several health habits and stress in adolescents. METHODS: We surveyed adolescents and their parents who visited an adolescent clinic in a general hospital for 8 manths. Structured questionnaires about status of several health habits and BEPSI(The Brief Encounterr Psychosocial Instrument) score were used. BEPSI is a quick stress measure that is composed of several items. RESULTS: This study included 486 adolescents and their 486 parents. Average number of good health habits was 3.2+/-1.7 and average BEPSI score was 2.1+/-0.6. The group that had more good health habits tended to mark lower BEPSI scores(p<0.05). There was a significant relationship between stress and each habit except sleep time of more than 7hrs, regular exercise and hobby. Smoker group and alcohol drinker group showed higher BEPSI scores, respectively. The conversation time between parents and adolescents had a significant relationship with BEPSI scores. CONCLUSIONS: Several health habits were significantly connected with stress in adolescents. We can assume that good health habits and conversation with their parents are important in the management of stress in adolescents.

MR imaging of the brain in 34 patients were reviewed to characterize the MR findings of brain damage due to perinatal hypoxic insult All the patients had a history of perinatal hypoxia and showed abnormal brain MR findings. Out of 34, eight infants were born premature and twenty-six were born at term or post-term. MR findings were analysed for the extent and location of abnormalities of the white matter, cortical abnormality. Corpus callosum atrophy, and abnormal progression of myelination. The major abnormalities were abnormal signal lesions or atrophy of the cerebral white matter and gyral atrophy of the cerebral cortex. The distribution of white matter lesions well correlated with maturity of the brain at the time of hypoxic insult. Periventricular and deep white matter lesions predominated in the premature-born patients. Corpus callosum atrophy was frequently seen. Reflecting the location of white matter injury. Delay in myelination was present in 55%. MR is a very useful diagnostic imaging modality and guide for the prediction of prognosis by accurate depiction of the location and extent of brain damage due to perinatal hypoxic insult.
