This study aims to argue fundamental issues on factors associated with revenues of hand injury patients to effectively manage hospitals specialized in hand injuries. The study employes 2,461 patients who entered S hospital from 2008 to 2010 with hand injuries. The followings are the results of the study. First, there is significant difference among occurrence of hand injuries with regard to demographics of patients. That is, it is likely to have longer average length of stay(ALOS) of male over female, of the elderly over infants and toddlers, and vice versa on average daily patient revenues. Also, compared to patients with traffic and labor insurance, patients with health insurance is likely to stay longer at lower daily cost. Fifth, demographics and incidence of hand injuries were significantly associated with average length of stay(ALOS) and average daily patient revenues. That is, male over female, age over 60 over any other age categories, patients with traffic and labor insurances over one with health insurance, cases with laceration, avulsion and bone transplantation over any other types of hand injury patients were factors significantly related to ALOS and average daily patient revenues. In sum, it is needed to focus on education and campaign to raise attentions on preventing various hand injuries. Also, managers at hospitals specialized in hand injuries should pay attention on issues such as reducing ALOS to run the organization effectively.

This study aimed to clarify any factors that may have effect on the appropriateness of hospital admission and hospitalization with the intention of facilitating more efficient occupancy of hospital beds and better medical services in the aspect of their quality, minimizing unnecessary occupancy of beds, and ultimately helping patients requiring acute treatments to use immediately hospitals. This paper selected 154 Stroke patients who left neurology department of one general hospital from March, 1, 2006 to September, 31, 2010 as targets to meet the rate according to medical care security and to see the trend of recent 4 years. As study method, this paper analized medical treatment record with AEP to evaluate the appropriateness of hospital admission and stay and the collected data was computerized through SPSS 12.0. Based upon the results above, the conclusion was drawn that the higher appropriateness of hospital admission and the shorter length of hospital stay will lead to the higher appropriateness of hospitalization. In other words, it is required to provide hospitalized patients with all kinds of behaviors including medical treatments and nursing care service, management of pharmaceuticals, tests, rehabilitation and symptoms, as well as instructions and information for patients. Meanwhile, as it was found that the length of hospital stay may affect the appropriateness of hospitalization, the longer length of hospital stay may result in reduced bed turnover rate. In this light, it is necessary to organize a task force team responsible for evaluation and control of the appropriateness of hospitalization and hospital stay length to improve the quality of medical service in a medical center, so that patients can leave the center timely. Ultimately, governmental supports such as expansion of long-term care facilities will reduce the necessary length of hospital stay so that patients with stroke can receive rehabilitative treatments and long-term care service shortly after completion of acute treatments.

The purpose of this study was to analysis of influence between of private health insurance and length of stay with cervical and lumbar simple sprain patients at Ubiquitous medical environment. They were diagnosed as having sprain of cervical and lumbar spine without neurological symptoms in hospitals and clinics from July 1, 2010 to February 29, 2012. This study was t-test, ANOVA and multiple regression analysis. The results were when the number of private health insurance was input as an independent variable, the subjects had one or two accidental insurances(${\beta}$=2.731, P=0.013), length of stay in beds was longer than they had no accidental insurance and when they had more than three ones(${\beta}$=4.991, P=0.000), length of stay was significantly longer. This study has a meaning in that it is domestic practical study which identified relationships between entry of private health insurance and length of stay.

The purpose of this study is to identify factors affecting length of stay(LOS) and death in tuberculosis(TB) patients by disease type, patient characteristic, admission and disease characteristic, and hospital characteristic from 2008 to 2017. Survey data was using Korean national hospital discharge in-depth survey data produced by Korea Disease Control and Prevention Agency. Study subjects were 10,634 inpatients with TB(A15, A16, A17, A18, A19, U88.0, U88.1, U84.30, U84.31) and analyzed frequency, chi-square test, Fisher's exact test, and logistic regression by using STATA 13.0. As a study result, the type of TB(extrapulmonary TB, multidrug-resistant TB, extensively drug-resistant TB), sex(woman), age(35-49, 50-64, 65-74, 75 years old or older), admission type(outpatient department), CCI(1-2 point, 3 point over), hospital location(metropolitan city) and bed size(300-499, 500-999, over 1000) were significantly influence LOS. Also, the type of TB(extrapulmonary TB, extensively drug-resistant TB), sex(woman), age(50-64, 65-74, 75 years old or older), residence(small town/rural), admission type(outpatient department), CCI(1-2 point, 3 point over), hospital location(provincial) were significantly influence death. In conclusion, the existing tuberculosis management has been patient management with rapid diagnosis and treatment following early detection. But other studies should be carried out for the system that identifies and supports high-risk groups of the long-term length of stay in hospital or high mortality rates as a result of treatment.

This study purposed to analyze the determinants of length of stay for patients having alzheimer dementia in geriatric hospitals. Sample data was collected from the National Patient Sample (NPS) produced by the Health Insurance Review & Assessment Service (HIRA) in 2009. Total 538 alzheimer inpatients over 65 years were used in the analysis. Patients were classified into 5 risk groups to represent the case-mix differences of patients. Organizational characteristics of geriatric hospitals such as number of beds, doctors, and nurses were included in the analysis model. In multivariate regression analysis, hospital variables were not statistically significant in explaining the length of stay. Two risk group were statistically significant in analysis, However, their signs of relationship with the dependent variable were opposite to the expectations. These results suggest that the characteristics of patients and hospitals did not have impacts on the length of stay. There will be needs to test the effects of other factor such as social needs which represents the socio-economic status of the family for the patients.

담관 낭종은 흔하지는 않지만, 외과적 절제가 필요한 주요 질환이다. 절제하지 않고 남겨두면 다른 질환으로의 이환이나 다양한 합병증에 의한 사망까지도 야기할 수 있기 때문에 적절한 수술적 치료가 필수적이다. 최근 수술에 따른 다양한 문제들이 계속 보고되고 있으며, 출생 전이나 건강 검진 시 발견되는 무증상의 담관 낭종의 수술 시기에 대해서도 아직 논란이 되고 있다. 저자들은 1995년부터 2009년까지 담관 낭종으로 수술 받은 환자 중 수술 받을 당시의 연령이 18세 이하인 32명 환자의 임상 양상과 수술 기록을 후향적으로 분석하여, 수술 성적에 영향을 주는 요인들을 알아보고자 하였다. 전체 32명 중 남자 10명, 여자 22명이었으며, 수술 당시의 평균 연령은 5.4세였다. 췌담관 합류이상은 9명(28.1%)이었으며, 평균 추적 관찰 기간은 34.6개월이었다. 술 전 증상을 호소한 환자는 30명(93.8%)이었으며, 복통(63.3%), 황달(40.0%), 구토(23.3%), 복부종물(16.7%), 발열(16.7%)등의 순서였다. 술 전 혈액 검사에서 AST/ALT의 상승이 18명(56.3%), 고빌리루빈혈증이 8명, 백혈구 증가증이 7명(21.9%)이었다. 술 후 합병증은 5명(15.6%)에서 나타났는데, 2명은 담관염이었고, 나머지 3명은 문합부 협착, 술 후 출혈, 장 폐쇄가 각각 1명 있었다. 술 후 평균 재원 기간은 12.2일 이었으며, 추적 관찰 기간 중 3명(9.0%)이 재입원 하였다. 수술 성적에 영향을 미치는 요인으로, 수술 당시의 나이가 많을수록 평균 수술 시간과 재원 기간이 증가하였다(p=0.004, p=0.028). 증상이 있었던 환자군에서 무증상 환자군보다 재원 기간이 더 길었다(p=0.001). 또한 췌담관 합류이상이 있었던 환자군에서 재입원율이 유의하게 높았다(p=0.005). 소아의 담관 낭종은 진단이 되면 증상 발현 전이라도 조기에 수술하는 것이 수술 시간 및 재원 기간을 단축시킬 수 있으며, 췌담관 합류이상이 동반된 경우에는 술 후에 재입원할 가능성이 높으므로 주의깊게 추적 관찰하는 것이 바람직할 것이다.

This paper analyzed the relationship between corporate debt financing and interest costs using micro firm-level data. We also analyzed the differences in this relationship by the year of 2008 financial crisis. We did not find a negative relationship between corporate interest costs and debt financing. Prior to the 2008 financial crisis, we found a negative relationship between corporate interest costs and debt financing. However, following the 2008 financial crisis, we found a positive relationship between corporate interest costs and debt financing. The impacts of the decrease in corporate interest costs on the increase in corporate debt financing are not significant in the Korean economy. After the 2008 financial crisis, the decrease in corporate interest costs is followed by a decrease in corporate debt financing.
