Background: The average hospital stay in most Korean teaching hospitals is longer than that of hospitals in developed countries. The investigation of average hospital stay of teaching hospitals is considered as an important measure to evaluate the effectiveness of hospital management. In this article authors analyzed the relationship of several variables (hospital ownership, number of beds, location of hospitals, number of physician) to length of hospital stay in each clinical department. Methods: The average hospital stay of each clinical department of 184 teaching hospitals was investigated. Authors reviewed the papers of teaching hospitals, that was reported to the Korean Association of Hospitals. Results: The means of hospital stay day of hospitals were not significantly different according to the number of hospital beds and location of hospitals. Only the difference of hospital stay according to ownerships was significant. The length of stay was the highest in public hospitals and the lowest in juridical hospitals. Conclusions: The number of beds and location of hospitals were not associated with the average hospital stay. But ownerships affected the average hospital stay. The national or public hospitals had the longest length of hospital stay. Number of specialists and number of all physicians were closely related to the average hospital stay.

Purpose: The aim of this study was to estimate optimization model of stay time in EMC. Methods: Data were collected at an EMC in a hospital using medical records from June to August in 2007. The sample size was 8,378. The data were structured by stay time for doctor visit, decision making, and discharge from EMC. Descriptive statistics were used to find out general characteristics of patients. Average mean and quantile regression models were adopted to estimate optimized stay time in EMC. Results: The stay times in EMC were highly skewed and non-normal distributions. Therefore, average mean as an indicator of optimal stay time was not appropriate. The total stay time using conditional quantile regression model was estimated about 110 min, that was about 166 min shorter than estimated time using average mean. Conclusion: According to these results, we recommend to use a conditional quantile regression model to estimate optimal stay time in EMC. We suggest that this results will be used to develop a guideline to manage stay time more effectively in EMC.

Back injury is frequent in industry workers and is a common cause of productivity loss. It has been reported that the insured of industrial accident insurance tend to stay in hospital longer than that of other types of insurance. The purpose of this study was to identify factors affecting the length of hospital stay for the treatment of back injury in the workers under industrial accident insurance. The results of this study help insurers develop reasonable industrial accident insurance policy for back injury claims and prevention strategies of work-related back injury. A total of 2,949 patients whose industrial accident insurance claim has been approved for the treatment of work-related back injury from January to December 1999 were included in this study. Relationship between the length of hospital stay and characteristics of patient, work place, back injury, and hospital were assessed using ANOVA, t-test, simple linear regression and multiple resgression. The major findings of this study are as follows : 1. The average length of hospital stay(LOS) was 91.82 days, respectively. 2. Characteristics of Patient LOS of male patients was longer than that of female patients, there was positive correlation between age and LOS and between average wage and LOS. Working period was negatively correlated with LOS. Distance from resident to hospital was positively correlated with LOS and LOS was significantly different dependign on type of duty. 3. Characteristics of Work Place LOS was significantly different depending on types of industry and geographical region of work place. Size of work place was positively correlated with LOS. 4. Characteristics of Back Injury Occupational back pain required shorter LOS compared with back injury due to electric shock. Number of concomitant illnesses and severity of disability were positively correlated with LOS. 5. Characteristics of Hospital Patients treated in community hospitals required significantly longer LOS. Treatment in hospitals with rehabilitation program required decreased LOS. This was more prominent as number of physicians specialized in rehabilitation. 6. Multiple regression analysis revealed that distance form resident to hospital, geographical region of work place, size of work place, number of concomitant illnesses, severity of disability, and type of hospital were factors affecting LOS.

This study analyzes the effects of hospital caseload on medical charges and length of stay for inpatients. Hospital caseload, representing the level of concentration of patients, was measured with the Internal Herfindal Index for three diagnosis related group (DRG) codes (appendectomy, operations on anus, and operations on uterus and adnexa). Ordinary least squares regression was used for analysis. Results showed that medical charges per inpatient and average length of stay significantly differed with respect to hospital concentration indices, and that hospital caseload was inversely related to operational performance for appendectomy and operations on uterus and adnexa. The significant negative relationship between concentration index and length of stay may decrease the total medical charges. The results imply that the expansion of the DRG payment system to hospitals will have a negative influence on their gross sales.

Purpose: This study was performed to investigate the factors affecting postoperative pain and length of hospital stay of liver transplantation donors. Methods: This is a retrospective study using the Electronic Medical Records (EMR) of 91 patients operated on at a tertiary hospital in Seoul, Korea in 2016. The collected data were analyzed using descriptive statistics, t-test, Mann-Whitney U test and Kruskal-Wallis test, Spearman's rank correlation, and multiple regression analysis. Results: The average age of the donors was $35.7{\pm}12.2$ years, and all donors were family members. PCA was applied for control pain in all patients, and 40.7% of PCA-related side effects were observed. The average length of hospital stay was $9.24{\pm}2.52$ days. The factors influencing the length of hospital stay were operative methods, pain control methods, and postoperative complications. The length of hospital stay was 1.29 days shorter if donors had no complication, 1.43 days shorter when only PCA was used, and 1.19 days shorter when laparoscopic resection was performed (Adjusted $R^2=0.17$, F=4.67, p<.05). Conclusion: The results of this study can be used as basic data for practical and effective postoperative nursing education and intervention of living liver donors.

Background: We investigated association between introduction of the diagnosis-related groups (DRG) system for anal operation and length of stay. Also, we investigated how it is different among hospitals with longer length of stay and among hospitals with shorter length of stay before introduction of the DRG system. Methods: We used data from Health Insurance Review and Assessment which were national health insurance claim data. Total 13,111 cases of anal surgery cases were included which were claimed by hospitals since July 2012 to June 2014. Two-level multivariable regression was conducted to analysis the association between length of stay and characteristics of hospital and patient. Results: Before introducing DRGs, the average length of stay was 5.41 days. After introducing DRGs, average length of stay was decreased to 3.92 days. After introducing DRGs, length of stay has decreased (${\beta}=-1.0450$, p<0.0001) and it was statistically significant. Among hospitals which had short length of stay (shorter than mean of length of stay) before introducing DRGs, effect of introducing DRGs was smaller (${\beta}=-0.4282$, p<0.0001). On contrary, among hospitals which had long length of stay (longer than mean of length of stay) before introducing DRGs, effect of introducing DRGs was bigger (${\beta}=-1.8280$, p<0.0001). Conclusion: Introducing DRGs was more effective to hospitals which had long length of stay before introducing DRGs.

Stroke is a high-risk disease. The future of the medical environment is that the proportion of elderly population is increasing, the average life expectancy is being increased, while the fatal rate of stroke will be low. These situation will due to the financial burden on medical insurance. The most important factor that affects on the medical costs of stroke patients is the length of stay. In this study the mean length of hospital for stroke stay was 21.81days(37.97days for intracerebral hemorrhage, 18.89 days for cerebral infarction). The payment per case of stroke was 6.86 million won(12.6 million won for intracerebral hemorrhage, 5.72 million won for cerebral infarction). The payment per case of intracerebral hemorrhage was 2.2 times more than that of cerebral infarction. The payment in the day of hospitalization was the highest and until the second day medical costs was high. After the third day medical costs tended to decline, after that seemed to show an almost constant level. The length of hospital stay was found to be the most important determinant of inpatient charges for stroke. Accordingly rational management of the length of stay will be beneficial to health care consumers, providers, states.

Purpose: We analyzed the medical costs for severely traumatized patients according to the severity and medical performance so that we could improve the financial balance of the trauma center. Methods: Retrospective analysis was performed on patients visiting SNUH Trauma Center from May 2011 to August 2011. Among a total of 55 severely traumatized patients, 31 patients whose medical bills were available and categorized were included in this study. The injury severity score (ISS) was calculated from the abbreviated injury score (AIS), which was updated in 2008,for each patient to assess the severity of injury. Major trauma was defined as an ISS above 15. Results:The 31 patients in this study included 20 males and 11 females. The average ISS was $33.23{\pm}16.65$ points. We categorize the patients into three groups according to ISS, 16-24: group 1, 25-40: group 2, and above 41: group 3. Total incomes, admission fees, surgery fees, and imaging test fees are shown in table 1. The costs seem to be higher costs in group 2, but this result has no statistical significance. Statistical significantly data are as follows: high radiologic test fees in group 1, short hospital stay in groups 1 and 2, and short ICU stay in group 1. The average hospital stay was 17 days, and the average emergency intensive care unit (EICU) stay was 7.5 days. Although the EICU stay was only 44% of the total hospital stay, the income from the EICU covers 79.4% of the total hospital income. Conclusion: From this study, we found several items that show relatively high medical income from severely traumatized patients visiting the SNUH Trauma Center. Most of the medical fees arise in the early phase of acute medicine usually in the ICU. Efforts to identify the items with high income and to minimize expenses will improve the financial structure of the Trauma Center,which is facing a budget crisis.
