간 질환은 다양한 원인에 의해서 이환되며 초기에는 이상증세가 나타나지 않아 조기 진단이 어려운 질병이다. 특히, 간 질환이 진행될수록 이상증세가 빈번히 나타날 뿐만 아니라 다양한 합병증을 동반할 수 있어 조기진단이 반드시 필요하다. 간 질환이 진행이 될수록 중증도가 높아지며 간조직 내에서는 결절(nodule) 생성 빈도가 높아진다. 간 질환을 비침습적으로 진단하기 위한 검사 방법 중 하나인 의료영상 진단에서도 간 결절과 간질환 중증도에 따라 판별이 어려운 경우가 빈번하게 발생하고 있다. 본 연구에서는 간 결절에 대한 점수를 산출하여 간 질환에 대한 중증도를 판단할 수 있는 정량분석 소프트웨어를 개발하였으며 임상 간 질환 환자의 의료 영상을 분석하여 임상적 의의를 찾고자 한다.

Purpose: The purpose of this study was to investigate the relationships among critical thinking disposition, problem solving ability, and triage competency in nurses working in Emergency Rooms (ERs). Methods: This cross-sectional study, conducted in August and September 2021, involved 118 ER nurses from three hospitals in the Gyeonggi-do metropolitan area. The data were analyzed using t-test, ANOVA, Scheffé test, Pearson correlation coefficients, and multiple linear regression analysis using SPSS for Windows version 25.0. Results: The mean score of triage competency among ER nurses was 87.63±15.65. In the regression model, age, ER experience, triage experience, critical thinking disposition, and problem solving ability predicted 52% of the triage competency. Both critical thinking disposition and problem-solving ability were noted to be significant (β=.32, p<.001; β=.36, p<.001, respectively). Conclusion: Critical thinking disposition and problem solving ability of ER nurses were identified as major factors in triage competency. To improve ER nurses' triage competency and enhance critical thinking disposition and problem solving ability, a systematic and ongoing program should be developed and implemented.

Thymectomy is an accepted therapeutic modality for patients with myasthenia gravis. The selection of patients for operation, the timing of operation and the surgical approach are still controversial. We reviewed 82 patientsraged 13 to 66 years; mean age, 37.7 years treated with transsternal thymectomy between January 1983 and December 1994. Patients were symptomatically staged according to the modified Osserman's classification. There was one hospital death and postoperative follow-up was obtained on 75 patients. During a mean follow up of 56.9 months, 64 patients (85.3%) benefited from the operation with complete remis ion achieved in 28(37.3%). The thyroid disease was present in 8 patients, of whom 7(87. 5%) achieved complete remission in contrast to 21 (31.3%) of the 67 patients without thyroid disease. The disease duration less than 2 years in 32 patients was associated with complete remission in 16 (50%) in contrast to remission in 12(27.4%) of the 43 patients whose disease duration was more than 2 years. In conclusion, the complete remission rate after transsternal thymectomy was affected by the presence of thyroid disease and disease duration. Myasthenia gravis with late onset(>40 years), thymoma pathology, old age and male gender appear to decrease the complete remission rate after transsternal thymectomy, although it was not statistically significant. There was no difference of complete'remission rate between normal and hyperplasia of thymus. Transsternal thymectomy was found to be beneficial in most patients with myasthenia gravis, but the majority of patients with ocular disease did not b nefit from the operation.

This study was done to identify the evaluation of CPSCS for neurocritical patients and provide effective nursing interventions for these patients. Data were collected from medical records of 203 neurocritical patients over 18 years of age who were admitted to the ICU of C University Hospital during the period from January 2008 to May 2009 and from October 2011 to December 2011. Collected data were analyzed through t-test, ANOVA test, Person's correlation analysis, trend analysis, stepwise multiple regression. The average CPSCS score was $112.09{\pm}18.91$ and there was a significant trendency for higher severity to lead to higher CPSCS's scores(survival: J-T:9.795, die: J-T:5.415, p=<.001). The scores of the respective areas follows measurement of vital sign($3.74{\pm}2.15$), monitoring($28.97{\pm}4.31$), activity daily living ($34.99{\pm}3.66$), feeding($.19{\pm}.98$), intravenous infusion ($18.20{\pm}8.27$), treatment/procedure ($16.93{\pm}4.90$), respiratory therapy($8.61{\pm}7.07$). By means of stepwise multiple regression analysis, the intravenous therapy & medication, respiratory therapy, activities of daily living, and monitoring area that contains the model showed a significant (F=2073.963, p<.001), and they explained 98.1% of CPSCS. These findings provide information that is relevant in designing interventions to enhance CPSCS among neurocritical patients in hospital.

Our study was carried out to develop the severity-adjustment model for length of stay in hospital for community-acquired pneumonia so that we analysed the factors on the variation in length of stay(LOS). The subjects were 5,353 community-acquired pneumonia inpatients of the Korean National Hospital Discharge In-depth Injury Survey data from 2004 through 2006. The data were analyzed using t-test and ANOVA and the severity-adjustment model was developed using data mining technique. There are differences according to gender, age, type of insurance, type of admission, but there is no difference of whether patients died in hospital. After yielding the standardized value of the difference between crude and expected length of stay, we analysed the variation of length of stay for community-acquired pneumonia. There was variation of LOS in regional differences and insurance type, though there was no variation according whether patients receive their care in their residences. The variation of length of stay controlling the case mix or severity of illness can be explained the factors of provider. This supply factors in LOS variations should be more studied for individual practice style or patient management practices and healthcare resources or environment. We expect that the severity-adjustment model using administrative databases should be more adapted in other diseases in practical.

This study was conducted to investigate the characteristics of private health insurance subscribers and non-subscribers as they relate to severely ill patients, and to identify the factors of participation. The study was conducted using the National Health and Nutrition Examination Survey for 2015, and data were analyzed using SPSS ver. 23.0. The subjects were 417 patients with severe disease (cancer, heart disease, cerebrovascular disease) over 19 years of age. Crossover analysis was employed to identify differences between the state of private health insurance participation, while binary logistic regression analysis was used to confirm the factors affecting private health insurance subscription. Analysis of the effects of the subjects on the private health insurance participation rate revealed that the social and demographic characteristics were higher in younger individuals regardless of sex, residence, or marital status. Moreover, higher household income, regardless of the education level, was associated with a higher participation rate of health insurance target individuals compared to medical benefit target individuals. The private health insurance participation rate was low and the explaining power was 51.7%, regardless of subjective health awareness and walking practice. Therefore, efforts should be made to improve the living environment and support local governmental programs for the elderly, low income households, socially vulnerable groups with limited activities and groups with limited health behavior. It is also necessary to consider various health policies, such as providing government health education or programs to prevent severe illness.

This study was to develop the assessment of medical service outcome using administration data through compared with hospital standardized mortality ratios(HSMR) in various hospitals. This study analyzed 63,664 cases of Hospital Discharge Injury Data of 2007 and 2008, provided by Korea Centers for Disease Control and Prevention. We used data mining technique and compared decision tree and logistic regression for developing risk-adjustment model of in-hospital mortality. Our Analysis shows that gender, length of stay, Elixhauser comorbidity index, hospitalization path, and primary diagnosis are main variables which influence mortality ratio. By comparing hospital standardized mortality ratios(HSMR) with standardized variables, we found concrete differences (55.6-201.6) of hospital standardized mortality ratios(HSMR) among hospitals. This proves that there are quality-gaps of medical service among hospitals. This study outcome should be utilized more to achieve the improvement of the quality of medical service.

Delayed treatment of acute cardiovascular and cereb-directrovascular diseases is related to poor prognosis and sequelae. For rapid and adequate treatment, role of prehospital emergency dispatchers for adequate triage and selection of hospital is important. In several advanced countries, emergency dispatchers use standardized protocols for decision of rescuer resources or distribution of patients at each hospital. ut, there has not been developed standardized protocol for emergency dispatchers in Korea. We developed standardized protocol based on NHS-direct and CTAS system for triage of symptoms of chest pain and Stroke. Groups with standardized protocol and without protocol was compared to triage result at emergency department which patient visited. The accuracy of triage on chest pain was 70.0% in group A, 94.0% in group B(p<0.01). The accuracy of triage in stroke symptoms was 64.2% in group A, 84.6% in group B(p<0.01). Conclusion: In this study, the accuracy of telephone triage with the protocol was more accurate than without the protocol. But, more studies are needed to generalize the protocol in South korea.

Background and Purpose: This study was undertaken to compare the sensitivity of the Repetitive Nerve Stimulation Test (RNST) between the upper and lower extremity muscles in myasthenia gravis(MG) patients. Material and Methods: The study population consisted of 20 normal persons(control group) and 10 MG patients(MG group). Using Stalberg's method. RNST was systemically performed in orbicularis oculi muscle. upper extremity muscles(flexor carpi ulnaris. abductor digiti quinti), and lower extremity muscles(tibialis anterior. extensor digitorum brevis. vastus medialis). Results: There were statistical differences of decremental response($mean{\pm}SD$) in orbicularis oculi and upper extremity muscles between the control and MG groups(p<0.05 or p<0.01). However, there was no statistical difference of decremental response($mean{\pm}SD$) to RNST in lower extremity muscles between the control and MG groups. There were highersensitivity in orbicularis oculi and upper extremity muscles than lower extremity muscles. Although positive reponse were detected in the lower extremity muscles, the positive response rates of lower extremity muscles were lower than o.oculi and upper extremity muscles. Conclusions: When the response rates of RNST in facial and upper extremity muscles are normal, may not be required RNST in lower extremity muscles.
