The purpose of this study was to investigate the determinants of total payment for mental and behavioral disorders patients admitted through the emergency room. Study data was selected from the Korean National Health Insurance sample data in 2009. This data was consisted of 753 inpatients who are 331 inpatients with only main sick(F31-F39) and 422 inpatients with main sick codes(F31-F39) and sub sick(F00-F99) admitted through the emergency room. SPSS v.18 was used for the statistical analysis such as descriptive analysis, t-test, ANOVA, and multiple regression analysis. In multiple regression analysis, significant variables affecting total payment of main sick patients were gender(p<.01), treatment result(p<.001), path of the emergency room(p<.001), and length of stay(p<.001). Also, main sick patients with sub sick were gender(p<.01), age(p<.001), treatment result(p<.001), path of the emergency room(p<.001), and length of stay(p<.001). These findings implied that it is necessary to build short, middle, and longterm program and system for high risk mental and behavioral disorders groups.

Objectives: This study aimed to report the effectiveness and outcome on the prognosis of pregnancy of traditional Korean medicine treatment for inpatients who had a traffic accident during pregnancy. Methods: The study is conducted by analyzing the medical records of hospitalized patients in a Korean medicine hospital. Seventy-six pregnant patients who got into car accidents from March 2015 to February 2020 were included. We performed statistical analysis by using Statistical Package for the Social Sciences(SPSS) ver. 25.0. To verify the effect of traditional Korean medicine treatment for traffic accidents during pregnancy, we analyzed improvement of symptoms. Also, we analyzed the prognosis of pregnancy and signs of premature birth or miscarriage during treatment to verify the applicability of traditional Korean medicine treatment for traffic accidents during pregnancy. Results: Among the symptoms of pain, there was a statistically significant decrease in lower back pain, post neck pain, headache, pelvic pain, knee pain, lower limb pain, wrist pain, and upper limb pain. Other systemic symptoms showed statistically significant improvement in nausea, abdominal pain, dizziness, and lower limb numbness. All confirmed cases reported normal pregnancy maintenance and delivery, and no miscarriage was reported. Two cases that showed signs of premature birth or miscarriage during treatment were unrelated or unclear with traditional Korean medicine treatment. Conclusions: Traditional Korean medicine treatment is effective and applicable for pregnant women injured by traffic accidents. Further studies are needed to identify the effectiveness and safety of traditional Korean medicine treatment for the sequelae of traffic accidents during pregnancy.

The study aimed to identify risk factors for falls as well as hospitalization status according to disease and demographic characteristics of demented inpatients by investigating the in-depth Injury Patient Surveillance System data collected by Korea Centers for Disease Control and Prevention(KCDC). Older adults over 60 years old who were diagnosed with dementia were included(n=1,732). Their data were analyzed after being assigned to either a fall group or a non-fall group. STATA was used for statistical analyses, such as frequency analysis, chi-square (χ²) test, and logistics regression. It was found that 8.0% of the demented inpatients experienced falls. According to the analysis on category of fall and non-fall group were statistically significant difference in age and Charlson Comorbidity Index(CCI) and bone density deficiency. Based on the logistic regression analysis of factors affecting falls, older adults over 80 are 2.386 times more likely to fall and based on a target with a CCI of 0, the risk of falls is 0.421 times lower, finally based on those without bone density disorder, the fall risk for those with bone density disorder was 3.581 times higher. Therefore, we expect that the important about the factors relating to falls identified in this can not only be found valuable for educating inpatients with dementia and care-givers, but also be used as reference that supports clinical professionals to make decisions on falls management for patients with dementia.

Background : The aim of this study was to examine the effectiveness of the critical pathway to diabetic patients who were admitted in the hospital. Methods : For establishment of critical pathway for diabetic patients, we organized the multidisciplinary care team. During 5 months, 31 diabetic inpatients were applied the critical pathway and the results were compared with 11 diabetic inpatients who were treated with conventional way. We assessed the patients satisfaction, knowledge on the disease, compliance of medical regimen, length of stay(LOS) and hospital cost. We used the computer program SAS for statistical analysis. Data were summarized with mean, and analyzed using t-test repeated measures ANOVA and Wilcoxon rank sum test. Results : Length of stay(LOS) was remarkably shortened in critical pathway group compared with the conventional treatment group($7.6{\pm}1.23$ vs $12.0{\pm}4.73$, p<0.000). Although LOS was significantly shortened in critical pathway group, patients satisfaction was much higher than conventional treatment group. There were no significant difference of knowledge on the disease, compliance of medical regimen and blood glucose level between two groups at discharge. Hospital cost of each patients also significantly decreased in critical pathway group(890,000 won vs 1,280,000 won, p<0.05). Conclusion : These results showed that establishment of critical pathway for diabetic inpatients with team approach is the one of the way to improve the quality of diabetic patients management and to enhance the efficiency of hospital management.

Objectives : This is a retrospective statistical analysis of the demographic and therapeutic characteristics influencing the continued improvement of symptoms in patients treated in 2014 for herniated lumbar discs at a Korean medicine hospital; thereby, providing clinical data to further improve medical services of Korean medicine. Methods : We investigated the demographic and therapeutic variables of all patients who were diagnosed with a herniated lumbar intervertebral disc and were hospitalized for more than 1 night at Dunsan Korean medicine hospital from January 1, 2014, to December 31, 2014. IBM SPSS 21.0 was used to conduct a logistic multiple regression analysis and a covariance analysis (ANCOVA) of the demographic and therapeutic variables collected from the electronic medical records and telephone surveys. Results : 1. A longer duration of hospitalization was significantly better for the maintenance of pain relief or a decrease in the pain after discharge. 2. Younger patients were significantly less likely to be treated with a Western medical treatment after discharge. 3. Most of the demographic and therapeutic variables were not statistically significant in regards to treatment for lower back pain since discharge. Conclusion : Some of the demographic and therapeutic variables had a positive effect on the prognosis at one year or greater in patients who received integrative Korean medical treatment for lumbar disc herniation. Continued and systematic research will be needed.

Objectives : This study aimed to analyze the management efficiency of Korean Medicine hospitals for recent 10 years(2001~2010) using the Data Envelop Analysis(DEA) model. Methods : We collected the management data of 23 Korean Medicine hospitals for DEA model from the Korean Oriental Medicine Hospitals' Association (KOMHA). Input variables of DEA model are numbers of beds, numbers of doctors, numbers of nurses and numbers of other staffs of each Korean Medicine hospitals. Output variables are numbers of inpatients and numbers of outpatients of each Korean Medicine hospitals. Based on the DEA model, we calculated the efficiency score of each Korean Medicine hospital and compared it by hospital's ownership, location, and size. Results : Average DEA efficiency scores of Korean Medicine hospitals by year ranged from 0.86 to 0.92. Private owned hospitals showed higher efficiency scores than the university affiliated hospitals with statistical significance (p=0.001). And Korean Medicine hospitals located in capital region of Korea(Seoul City, Incheon City, Gyeonggi-do) and the rest Korean Medicine hospitals did not show statistical difference (p=0.516). Lastly, Korean Medicine hospitals with different size did not show statistical difference in management efficiency (p=0.499). Conclusion : We have found that Korean Medicine hospitals management efficiency have not changed throughout 10 years, and that different ownership forms of Korean Medicine hospital show statistical difference in management efficiency while location, and size do not.
