The purpose of this study was to explore the predictors of turnover intention among nurses working in general hospitals. The subjects were 181 nurses who worked in two general hospitals in Gyeonggi-do, Korea. Data were collected from June to November 2018, and analyzed by descriptive statistics, Independent t-test, One-way ANOVA, Pearson's correlation coefficients, and Stepwise multiple regression analysis, using SPSS/WIN 21.0. The main findings of this were as follows. The mean scores for the nursing work environment, professional self-concept, job satisfaction and turnover intention were $2.43{\pm}0.38$, $2.60{\pm}0.25$, $2.59{\pm}0.29$ and $3.43{\pm}0.72$ points. Turnover intention is negatively correlated with the nursing work environment (r=-.43, p<.001) and job satisfaction (r=-.46, p<.001). Factors influencing turnover intention were job satisfaction(${\beta}=-.47$, p<.001), nursing work environment(${\beta}=.32$, p<.001), professional self-concept(${\beta}=.20$, p<.001), and total length of a clinical career(${\beta}=-.15$, p<.05) showing an explanatory power of 38%. Since various variables influence the turnover intention of nurses, it is necessary to improve the nursing environment in the medical field rather than the strategy to increase the number of simple nurses. In the university, education for establishing through introductory nursing specialty is needed.

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.

Nursing home plays a role in providing elderly care in the context of China's rapid population aging, but little understanding of the efficiency of the nursing homes. In this paper, we investigated the efficiency in nursing homes using Data Envelopment Analysis (DEA) and Malmquist index (MPI) for the modeling of the number of nursing home beds, fixed assets, and medical personnel as input variables, and the number of elderly people of self-care, the number of elderly people of partial self-care, the number of bed-ridden elderly people and the income of nursing homes as output variables. Stratification analysis showed that the top two provinces in the DEA-CCR yield were Beijing and Shanghai in the five-year survey period. Four provinces (Beijing, Jiangsu, Shandong, and Shanghai) scored 1.00 in terms of DEA-BCC yield. The MPI analysis showed that Hainan ranked the highest five-year average in the included provinces. In terms of resource utilization, internal management, operation scale, and other aspects, the nursing homes in the provinces with high-efficiency evaluation results show high efficiency and technological progress, whereas the areas with low-efficiency evaluation showed a feature of the improving technical efficiency.

This study was performed to generate basic data to establish a health promotion plan for residents of Chungcheongbuk-do by identifying characteristics of discharged patients residing in the Chungcheongbuk-do area from an In-Depth Post-Discharge Injury Survey reported by the Korea Centers for Disease Control and Prevention(KCDCP). The Report provided data on demographic characteristics, medical institution use characteristics, medical use characteristics, and disease characteristics of patients discharged from medical institutions with 100 or more beds from 2013 to 2017. The total number of Chungcheongbuk-do residents who were admitted and discharged from 2013 to 2017 was estimated to be 1,656,590, and the discharge rate was 21,089, which was higher than the national average of 13,882 in 2016. The regions where the discharge rate increased during this period include Goesan, Yeongdong, Boeun, Okcheon, Jeungpyeong, and Eumseong-gun, which are mainly rural areas. Among the patients hospitalized and discharged from hospitals outside the Chungcheongbuk-do area, the discharge rate of patients who used hospitals in Incheon/Gyeonggi areas and Daejeon/Chungnam areas increased slightly. Among the malignant tumor patients, the number of lung cancer(included trachea & bronchial cancer) patients was the highest. In addition, the discharge rate was highest for patients with respiratory diseases. This study suggests that efforts need to be made to lower the discharge rate for infection, circulatory disease, genitourinary disease, and musculoskeletal disorder patients
