This study was carried out to provide basic data for prevention of death from injuries and traumas by analyzing the characteristics of length of hospital stay of patients with injuries and traumas, utilizing in-depth investigation data of discharged injuries. The study subjects were 233 patients discharged from January 1 to December 31 in 2014 whom the final treatment result was 'death' and the main diagnosis were injuries and accidental external causes(S00-T98). According to the research findings, the length of hospital stay of females was longer than that of males. Based on the main diagnosis, the longest length of hospital stay had complication of other internal prosthetic devices, implants and grafts(T85). In conclusion, it is necessary to develop a policy to identify the factors affecting the length of hospital stays of patients and to manage them intensively.

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

This study was conducted to investigate the factors that affect the length of stay in hospital for schizophrenic patients. Of the data from the in-depth injury patient surveillance system, the final subject included 2,239 patients with schizophrenia in their final diagnosis. Using SPSS 18.0, a hierarchical regression analysis was performed by sequentially entering the explanatory variables by setting sociodemographic characteristics, discharge characteristics and hospital characteristics as explanatory variables and the length of stay in hospital as a dependent variable. The findings showed that the sociodemographic characteristics had the highest explanatory power and the explanatory power changed when the explanatory variable of the hospital characteristics was added, as opposed to the discharge characteristics. Male, type-1 medicaid, Chungcheong-do and the number of beds were found to be the factors that mostly affect the length of stay. Since this study used the secondary data, it has a limitation in terms of additional variables that could better explain the length of stay for schizophrenic patients. Nevertheless, it has an implication in that it investigated a large scale of data on a national level. For the effort of reducing the length of stay, it is suggested that an effort should be made at the national level, by focusing more on the hospital characteristics as well as the individual characteristics of patients.

This study selected in-depth discharge damage survey data and analyzed 92,364 patients whose main diagnosis was S00-T98 (damage, addiction, and specific other results due to external factors) based on the Korean Standard Classification of Diseases and Deaths (KCD-7th) among patients discharged from the hospital after inpatient treatment from January 2016 to December 2018. As a result of analyzing the general characteristics of injured and traumatic patients, the incidence rate of men was higher in gender, and the incidence rate of women increased as the year increased. As a result of analyzing the characteristics of injury and trauma patients other than injury, the injury intention had a high rate of unintentional damage, the damage place was the highest on the road/road, and it showed a decreasing trend as the year increased, and it showed an increasing trend in the residential area. It can be used as basic data for the establishment of a related system to prevent damage as a result of subsang.

This study aims to develop the severity-adjusted length of stay(LOS) model for acute stroke patients using data from the hospital discharge survey and propose management of length of stay(LOS) for acute stroke patients and using for Hospital management. The dataset was taken from 23,134 database of the hospital discharge survey from 2004 to 2009. The severity-adjusted LOS model for the acute stroke patients was developed by data mining analysis. From decision making tree model, the main reasons for LOS of acute stroke patients were acute stroke type. The difference between severity-adjusted LOS from the decision making tree model and real LOS was compared and it was confirmed that insurance type and bed number of hospital, location of hospital were statistically associated with LOS. And to conclude, hospitals should manage the LOS of acute stroke patients applying it into the medical information system.

As the number of aged population rapidly goes up, the cases of stroke and the related medical expenses continuously increase. The purpose of this study is to investigate the mortality of stroke patients based on CCI(Charlson Comorbidity Index) by utilizing the Korea National Hospital Discharge Injury Survey, analyzing the factors associated with the mortality of stroke patients. We analyzed 21,494 cases which are classified as the death of strokes aged over 20 years by using the Korea National Hospital Discharge Injury Survey between the year 2005 and 2010. In order to find out the mortality based on CCI and status of comorbidity, we used the technical statistics. We performed a logistic regression analysis to examine the reasons for the mortality of the strokes. We found that the independent variables for the influence of the mortality of strokes include age, type of insurance, residence urban size, size of hospital beds, the location of hospital, admission route, physical therapy, brain surgery, type of stroke, and CCI. This indicates that the effective monitoring on the age, types of stroke, comorbidity is needed. In addition to this, more medical support toward medicaid patients are needed, too. We believe that these results will be used positively for the evaluation of the stroke patients, providing the basic materials for the further research on the establishment of the health-related policy.

This study is analyzed the implementation of medical aid for patients over 65 years of age who are among the discharged from hospitals with the capacity of over 100 beds. I have analyzed it with the data from an in-depth study of injury surveillance of discharged patients from hospitals done in a national project in 2004. After analyzing the results of the data from the beginning of this national project to the data collected in 2008, I could get the results that the rate of discharged patients over 65 years of age increased every year. Among them, the rate of discharged women was higher than that of the men, and the rate of deaths while at the hospital for patients over 65 years of age was higher than that of patients less than 65 years of age. The rate of operations done on patients over 65 was lower than that of patients under 65 years of age. The results of a diagnosis of popular symptoms showed that the rate of the diagnosis of cerebral infraction and structure of the heart at the circulatory organ was higher. In addition, the rate of the diagnosis of lung cancer, pneumonia, and chronic obstructive lung disease was higher, as well as the rates of gastric cancer, diabetes, liver cancer, and colorectal cancer. The results showed that the operation of the nerve system or cardiovascular system were higher. Therefore, according to this result, we should prioritize and allocate resources to the elderly people when setting up a management policy. And also, we should promote healthcare for elderly people after considering the characteristics of the implementation of medical aid in preparation of a super-aged society.

This study investigated the characteristics and factors affecting inpatient infants, children, and adolescents who experienced falling, using NHDIS data from 2008 through 2017, The study analyzed data of 116 patients who were under 18 and who experienced injuries (KSCD, S00-S99) by falling (KSCD, W00-W19). Frequency analysis, cross-tabulations, and multiple regression analysis were conducted, using SPSS 23. There were more boys than girls, and most of the falls occurred at the ages of over one to under six years old. Most of the children had respiratory diseases, and most had open wounds or bruises due to falling. Also, most of the falls were related to the bed. In the factor analysis, age (β=.318), the main diagnosis (β=.231), and injury (β=.169) except gender affected falling. This suggests that it is necessary to conduct fall prevention education for children, considering the developmental stage characteristics and age group. It is necessary to screen the risk group such as children with a disease with relatively less restriction of activities or with a hyperactive disorder, and to develop a related manual. Hopefully, the results will be used as the basic data for fall prevention education and creating a fall prevention manual according to the characteristics of children's developmental stage for patients who need hospitalization, their caregivers, and the relevant medical team.

This study aimed to understand the differences in general characteristics, principal diagnosis, injury-related characteristics, and types of transportation accidents between young-old and old-old patients who were hospitalized owing to injury based on data from the Korean National Hospital Discharge In-Depth Injury Surveys. We used a complex sample cross tabulation analysis (chi-square test) and complex sample generalized linear model (t-test). Therefore, the primary focus of healthcare professionals working with the old-old should prevent falls in the home and increase the available medical care, financial aid plans, and psychosocial support for aging. Additionally education on traffic accident prevention and road safety is particularly important for old-old patients.

This study aims to design a Severity-Adjusted LOS(Length of Stay) Model in order to efficiently manage LOS of AMI(Acute Myocardial Infarction) patients. We designed a Severity-Adjusted LOS Model with using data-mining methods(multiple regression analysis, decision trees, and neural network) which covered 6,074 AMI patients who showed the diagnosis of I21 from 2004-2009 Korean National Hospital Discharge in-depth Injury Survey. A decision tree model was chosen for the final model that produced superior results. This study discovered that the execution of CABG, status at discharge(alive or dead), comorbidity index, etc. were major factors affecting a Sevirity-Adjustment of LOS of AMI patients. The difference between real LOS and adjusted LOS resulted from hospital location and bed size. The efficient management of LOS of AMI patients requires that we need to perform various activities after identifying differentiating factors. These factors can be specified by applying each hospital's data into this newly designed Severity-Adjusted LOS Model.
