Purpose: The purpose of this study was to identify characteristics of patients who were recipients of decision-making DNR, to describe the situations of DNR, and to analyze the APACHE III and MOF scores. Method: Data collection was conducted through reviews of medical records of 51 patients and through interviews with families of patients who were decision-makers for DNR at C university K Hospital located in Seoul from April to September 2002. Results: The men's APACHE III and MOF scores were higher than the women's and the non cancer patients were higher than cancer patients. Some 80.4% of DNR orders was by communication, while 11.8% of consents were written. Each of APACHE III and MOF scores of patients in the intensive care unit was higher than the patients in general ward at both points of admission and decision-making of DNR. APACHE III and MOF scores positively correlated statistically with each other. Conclusions: The findings of this study suggest that APACHE III and MOF scores be useful for decision-making of DNR as a tool measuring severity.

This study concerns with an applicability of the management science approach to the score adjustment among the College Scholastic Aptitude Test(CSAT) optional subjects. A linear programming model is developed to minimize the sum of score distortions between optional subjects. Based on the analysis of the 377,089 CSAT(2010) applicants' performances in social science test section, this study proposes a new approach for the score equating or linking method of the educational measurement theory. This study makes up for the weak points in the previous linear programming model. First, the model utilize the standard score which we can get. Second, the model includes a goal programming concept which minimizes the gap between the adjusting goal and the result of the adjustment. Third, the objective function of the linear programing is the weighted sum of the score distortion and the number of applicants. Fourth, the model is applied to the score adjustment problem for the whole 11 optional subjects of the social science test section. The suggested linear programming model is a generalization of the multi-tests linking problem. So, the approach is consistent with the measurement theory for the two tests and can be applied to the optional three or more tests which do not have a common anchor test or a common anchor group. The college admission decision with CSAT score can be improved by using the suggested linear programming model.

Delayed access to surgery may lead to deterioration in the patient condition, poor clinical outcomes, increase in the probability of emergency admission, or even death. The purpose of this work is to decide the number of patients selected from a waiting list and to schedule them in accordance with the operating room capacity in the next period. We formulate the problem as an infinite horizon Markov Decision Process (MDP), which attempts to strike a balance between the patient waiting times and overtime works. Structural properties of the proposed model are investigated to facilitate the solution procedure. The proposed procedure modifies the conventional value iteration method along with the binary search technique. An example of the optimal policy is provided, and computational results are given to show that the proposed procedure improves computational efficiency.

As a number of new college students is gradually decreasing, each college is trying to find various solutions for gathering many students and operating a school. In specialty, information such as entrance examination and matriculation status data is very important for a college to decide a direction of admission and public relations policy, and increase welfare of the school. Therefore, it is seriously needed for a school to introduce a matriculation management system that can do the effective analysis through various entrance examination and matriculation status data and decision factors of school. In this study, I developed a matriculation management system which can analyze information of applicants, successful candidates and registrants based on national framework data. It is expected that the developed system can provide appropriate and rational information for public relations policy and operation to a college.

Purpose: For trauma patients, an early-transport and an organized process which are not delayed in hospital stage are necessary. Our hospital developed a procedure, the trauma Critical Pathway (CP), through which a traumatic patient has the priority over other patients, which makes the diagnostic and the therapeutic processes faster than they are for other patients. Methods: The records of patients to whom Trauma CP were applied from January 1, 2011 through April 15. 2012. were reviewed. We checked several time intervals from ER visiting to decision of admission-department, to performing first CT, to applying angio-embolization, to starting emergency operation and to discharging from ER. In addition, outcomes such as duration of ICU stay, hospital stay and mortality were checked and analyzed. Results: The trauma CP was applied to a total of 143 patients, of whom, 48 patients were excluded due to pre-hospital death, ER death, transferring to other hospital and not severe injury. Thus 95 patients (male 64, 67.3%) were enrolled in this study. Fifty-nine patients(62.1%) were injured by the traffic accident. The mortality rate was 10.5% and the mean Revised Trauma Score (RTS) of the patients was $6.4{\pm}2.0$. After visiting ER, decision making for admission was completed, on average, in 3 hours 10 seconds. The mean time intervals for the first CT, angio-embolization, surgery and discharge were 1 hour 20 minutes, 5 hours 16 minutes, 7 hours 26 minutes and 6 hours 13 minutes, respectively. Conclusion: The trauma CP did not show the improvement of time interval outcome, as well as mortality rate. However, this test did show that the trauma CP might be able to reduce delays in procedures for managing trauma patients at the university-based hospitals. To find out the benefit of CP protocol, a large scaled data is required.

Background: An appropriate use of hospital beds can improve productivity of hospital significantly. The authors' previous study revealed that approximately one third of Korean hospital bed days and one sixth of admissions were inappropriately used, when it was measured by Appropriateness Evaluation Protocol(AEP) and Delay Tool modified into Korean situation by the authors. This study aims to evaluate applicability of the instruments in a new hospital. More specifically the study aims to measure appropriateness of the instruments used by newly trained nurse reviewers at a new hospital setting. Methods: In order to evaluate applicability of these instruments, agreement rates of the scores recorded by newly trained nurse reviewers with by skilled nurse reviewer and also compared with the scores recorded by physician's implicit decision were assessed. Agreement rates were derived from concurrent application of AEP and Delay Tool to 52 admissions and 104 patient days from internal medicine, pediatrics, and general surgery of one university hospital. Overall agreement rate, specific nonacute agreement rate, and kappa statistics were used to indicate level of agreement. Results: Overall agreement rates on appropriateness between newly trained nurse reviewers and skilled nurse reviewer were 100% in admission and 98% in bed days. Overall agreement rates on reason for inappropriateness between newly trained nurse reviewers and skilled nurse reviewer were 96% in admission and 91% in bed days. Overall agreement rates between newly trained nurse reviewers and physician reviewer were 86% in admission and 87% in bed days. Conclusion: Results indicated that AEP and Delay Tool were applicable to a new hospital in detecting inappropriate utilization of beds and reasoning of the inappropriateness. These instruments could contribute to enhance efficiency of hospital use, through continuous monitoring of level of inappropriate hospital use at national or individual hospital level.

Objectives: This study aims to determine the risk factors predicting rehospitalization by comparing three models and selecting the most successful model. Methods: In order to predict the risk of rehospitalization within 28 days after discharge, 11 951 inpatients were recruited into this study between January and December 2009. Predictive models were constructed with three methods, logistic regression analysis, a decision tree, and a neural network, and the models were compared and evaluated in light of their misclassification rate, root asymptotic standard error, lift chart, and receiver operating characteristic curve. Results: The decision tree was selected as the final model. The risk of rehospitalization was higher when the length of stay (LOS) was less than 2 days, route of admission was through the out-patient department (OPD), medical department was in internal medicine, 10th revision of the International Classification of Diseases code was neoplasm, LOS was relatively shorter, and the frequency of OPD visit was greater. Conclusions: When a patient is to be discharged within 2 days, the appropriateness of discharge should be considered, with special concern of undiscovered complications and co-morbidities. In particular, if the patient is admitted through the OPD, any suspected disease should be appropriately examined and prompt outcomes of tests should be secured. Moreover, for patients of internal medicine practitioners, co-morbidity and complications caused by chronic illness should be given greater attention.

Here we report a case of ruptured dissecting aneurysm of the posterior inferior cerebellar artery[PICA] treated with proximal PICA coil occlusion using an endovascular technique. A 28-year-old man presented with acute severe headache and vomiting followed by seizure. At admission, he was drowsy, with diplopia and right ankle hypesthesia. Computed tomographic scans demonstrated a subarachnoid hemorrhage. Cerebral angiography demonstrated a dissecting aneurysm of the left proximal PICA. One day after the bleeding episode, he was undergone proximal PICA coil occlusion using an endovascular technique. The patient's postoperative course was uneventful. The decision that led to the choice of treatment is discussed.

목적: 가족구성의 특성이 건강에 미치는 영향에 관한 다양한 실증 연구들이 꾸준히 보고되어 왔다. 우리나라에 말기암환자의 가족구성의 특성에 대한 연구가 부족하여 이에 본 연구에서는 호스피스 병동에 입원하고, 사망한 말기암환자의 가족구성의 특징을 파악하고 호스피스 완화의료 이용과의 연관성에 대해 알아보고자 하였다. 방법: 2009년 1월부터 2014년 3월까지 일개 호스피스 병동에 입원 후 48시간 후 사망한 말기암환자의 134명의 의무기록을 후향적으로 분석하였다. 환자들의 인구사회학적 및 임상적인 특성을 확인하여 동거배우자 유무에 따른 차이를 살펴보았으며, 암 진단 후 호스피스 입원까지 기간(개월) 및 입원 후 사망까지의 생존기간(일)을 산출하여 가족구성과의 연관성을 알아보았다. 결과: 암 진단 후 호스피스 입원까지 기간의 중앙값 13개월을 기준으로 나눈 Group B(13개월 이후)에서 배우자 동거군의 비율이 통계적으로 유의하게 높았다(P<0.01). 주의사결정권자는 Group A에서는 자녀인 경우가 59.0%, B에서는 배우자가 52.9%로 많았다(P=0.04). 호스피스 입원 후 사망까지 기간의 중앙값 20일을 기준으로 Group 1(20일 미만)과 Group 2(20일 이상)로 나누어 살펴보았을 때 두 군 간의 가족구성의 특징은 통계적으로 유의한 차이가 없었다. 결론: 가족구성의 특성 중 배우자의 유무가 말기암환자의 호스피스 완화의료 이용 시기에 영향을 미치는 요인으로 나타났으며, 말기암 환자와 가족의 보다 더 효율적이고 적절한 호스피스 완화의료 이용을 위해 가족 구성의 특성을 파악하는 것이 도움이 될 수 있다.
