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.

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.

BACKGROUND: To evaluate the clinical outcomes and associated repair integrity in patients treated with arthroscopic repair for a transtendinous rotator cuff tear followed by resection of the remnant rotator cuff tendon. METHODS: Between July 2007 and July 2011, we retrospectively reviewed patients who were treated for transtendinous full-thickness tears in the tendinous portion of the rotator cuff by arthroscopic repair. Clinical outcomes were evaluated using the American Shoulder and Elbow Surgeons (ASES) score, the Shoulder Rating Scale of the University of California at Los Angeles (UCLA), the Constant-Murley score, a visual analogue scale (VAS) pain score, and range of motion (ROM). The repair integrity was determined by magnetic resonance imaging or ultrasonography. RESULTS: There were 19 shoulders with transtendinous full-thickness tears in the tendinous portion of the rotator cuff. The ASES, UCLA, Constant-Murley, and VAS pain scores showed significant improvements in function and symptoms (all p<0.001). The active ROM for forward flexion and abduction was also significantly improved (p=0.002 and p<0.001, respectively). The postoperative radiological examination showed cuff integrity without a re-tear in 68.4% of patients. However, the UCLA, ASES, and Constant-Murley scores were not significantly different between healed and re-torn group (p=0.530, p=0.885, and p=0.262, respectively). CONCLUSIONS: Although repair of transtendinous rotator cuff tears followed by resection of the remnant rotator cuff tendon in the footprint has a relatively high re-tear rate, no significant difference was observed in the short-term clinical results between the re-tear and healed groups.

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.

BACKGROUND:Acute vestibular neuronitis is the disease of which the etiology and pathophysiology are largely unknown . But the viral infection and ischemia of the labyrinth and the vestibular nerve are considered as general etiology. This study was performed to support the viral infection rather than the ischemic theory. MATERIALS & METHODS:We studied seventy years old female patient who showed painful vesicles on left auricle and vertigo with spontaneous nystagmus to the right side. We performed physical examination, serologic test, ENG test, pure tone audiogram, brain magnetic resonance imaging and polymerase chain reaction. RESULTS:We found small vesicles and vascular injection in left EAC, herpes zoster IgG positive, spontaneous right beating in electronystagmograpy, 54% left canal paresis in Caloric test , decreasing left side Tc in velocity step rotatory test, decresed gain, deviation to left in symmetry and phase lead in sinusoidal harmonic acceleration test, normal range hearing in pure tone audiogram, microangiopathy on cortex in brain MRI and negative PCR. CONCLUSION:This case supports viral infection etiology rather than ischemia in vestibular neuritis. But more studies to find the etiology of vestibular neuronitis are required.

PURPOSE: There have been repoty on radiological features of lower respiratory track infection in infants and children caused by RSV(respiratory syncytial virus) in KOREA. The aims of this study were to summarize radiological features of lower respiratory tract infection caused by common viral agents other than RSV and to find any specific radiological features which might provide clue to the etiologic diagnosis. MATERIALS AND METHODS: We retrospectively analyzed radiological features in 51 children with symptoms of lower respiratory tract infection and identification of viral agents(except RSV). They included parainfluenza (n=22), adenovirus(n=16), influenza A(n--11), influenza B(n=2) virus infections. The mean age of the patients was 23 months. RESULTS: Major radiological findings of viral lower respiratory tract infection were bilateral parahilar peribronchial infiltration(62%), bilateral overaeration(60%), atelectasis(59%)(segmental or subsegmental atelectasis(43%), Iobar atelectasis(16%)) and patchy or confluent consolidation(20%). Pleural effusion was seen in only one case and hilar adenopathy was not observed in any of them. In the cares of adeno virus, consolidation was seen in 5 cases(31%) including 3 cases919%) of extensive confluent consolidations and overaerations were less frequent findings(44%) than in other viruses. In 24 patients with radiological follow up for more than 1 week, consolidation improved most rapidly, while was persistent atelectasis. CONCLUSION: The major radiologic features in vital lower respiratory tract infection(except RSV) were overinflation, bilateral peribronchial infiltration and atelectasis. In adenoviral infection, confluent consolidations which are usually seen in bacterial pneumonia were more common findings than in other viral lower respiratory tract infections.
