This study was an attempt to encourage the development of a rehabilitation delivery system and programs as a substitute service for hospitalization on the case of car accident patients, such as hospital based home health care nursing services. Various substitute services for hospitalization are required to curtail the length of stay for inpatients who were hospitalized with car accident compensation insurance. It focused on developing an estimation an early discharge day for car accident inpatients based on detailed statements of treatment for 111 inpatients who were hospitalized at the General Hospital in 1997. This study had four specific purposes as follows. First. to find out the utilization of medical services. Second, to estimate the time of early discharge and income increasing effect based on early discharge for those patients. Third, to identify the factors affecting total medical expenditure and the length of stay for those inpatients. Forth, to figure out the need of utilizing home health care nursing service for accident patients. In order to analyze the length of stay and medical expenditure for inpatients who were hospitalized due to car accidents, the authors conducted micro- and macro-analysis of medical and medical expenditure records. Micro-analysis was done by nominal group discussion of 4 expertise with the critical criteria, such as a decrease in the amount of treatment after surgery, treatments, tests, drugs and changes in the test consistency, drug methods, vital signs, start of ROM exercise, doctor's order, patient's outside visiting ability, and stable conditions. In addition to identifying variables affecting medical expenditure, and the length of stay and income effect due to early discharge day, the data was analyzed with a multiple regression analysis and linear regression analysis model by SPSS-PC for windows and Excell program. Results of this study were as follows. First. the mean length of stay was 50.3 days. whereas the mean length of stay due to early discharge was 34.3 days at the hospital. The estimation of time of early discharge depended on the length of stay. The longer the length of stay, the longer the length of time of early discharge : for instance a length of stay under 10 days was estimated as correlating to a mean length of stay of 6.6 days and early discharge of 6.5. The mean length of stay was 217.4 days and the time of early discharge was 110.1 respectively. The mean medical expenditure per day was found to be 169.085 Won and the mean medical expenditure per day showed negative linear trends according to the length of stay at the hospital. The estimation results of the income effect due to being discharged 16 days early was around 2,244,000 won per bed. However. this sum does not represent the real benefits resulting from early discharge, but rather the income increasing amount without considering medical prime cost in the general hospital. Therefore, further analysis is required on the cost containments and benefits as turn over rate per bed as the medical prime costs. The length of stay was most significant and was positive to the total medical expenditure, as expected. Surgery and patient's residential area was also an important variable in explaining medical expenditure. The level of complications was the most significant variable in explaining the length of stay. There was a high level for need a home health care nursing service which further supports early discharge for accident patients. In addition, when the patient was discharged. they needed follow up care for complications suffered during the car accident. $86.8\%$ of discharged patients responded that they needed home health services after early discharge. From these research findings, the following suggestions have been drawn. Strategies on a health care delivery system must be developed in order to focus on the consumer's needs and being planned for 21 century health policy in Korea. Community based intermediate facilities or home health care should be developed for rehabilitation services as a substitute for hospitalization in order to shorten the length of stay would be. A hospital based home health care nursing service. it would be available immediately to utilize by patients who want rehabilitation services as a substitute for hospitalization with the cooperation of car insurance companies.

Purpose: Firefighters are vulnerable to burn injury during firefighting. In extensive fires, conducted heat and radiant heat can cause burn injury even though firefighters are not directly exposed to fire. There has been increasing interest in the health problems of firefighters considerably since Hongje-dong fire of 2001, which claimed the lives of six fireman. However, there have been no studies done on the characteristics of firefighter burn injuries in South Korea. Therefore, we investigated the characteristics of firefighter burn injuries in a burn center. Methods: A retrospective, single-center research was performed between Jan 2006 to Dec 2015. 24 firefighters came to the burn center. The electronic medical records of patients were reviewed. Results: Flame burns (87.5%) were the major cause of burn in firefighter. All the patients suffered second-degree or third-degree burns. Mean burn size was 6.1±6.7%. 22 of 24 patients were hospitalized and 2 of 22 hospitalized patients admitted to intensive care unit. Mean length of hospitalization was 29.1±23.7 days and mean length of intensive care unit hospitalization was 6.0±1.4 days. The face was the site most commonly burned, representing 25.8% of injuries. The hand/wrist, upper extremity, and neck were the next largest groups, with 19.4, 12.9, 11.3% of the injuries, respectively. Conclusion: Firefighter burn injuries occur to predictable anatomic sites with common injury patterns. The burn size was small but, admitted patients need about 30 days of hospitalization.

We reviewed 9 cases of pyogenic spondylodiscitis following percutaneous endoscopic lumbar discectomy (PELD). Microbiologic cultures revealed 6 causative organisms. Five patients were managed conservatively and four were treated surgically. The mean follow-up period was 20.6 months and the average length of hospitalization was 24 days. Radiological evidence of spinal fusion was noted and infection was resolved in all patients. Although PELD is a safe and effective procedure, the possibility of pyogenic spondylodiscitis should always be considered.

Purpose: This study explored and evaluated the systemic complications resulting from the bite of Korean venomous snake, focussing on hematologic and neurologic features. Methods: Medical records (demographic data, clinical measurements including laboratory results, severity score, and amount of antidote administration, and hospitalization course) of consecutive patients who presented with snakebites to two university teaching hospital during a 10-year period were retrospectively reviewed. Subgroup analysis was conducted for evaluations of anti-acetylcholine esterase administration in complicated victims. Results: The 170 patients displayed occurrence rates of hematologic and neurologic complications of 12.9% and 20.6%, respectively. Among 22 patients with hematologic complications, isolated thrombocytopenia was evident in eight patients (36.4%), prothrombin time (PT) / activated partial thromboplastin time (aPTT) prolongation in 11 patients (50.0%), and both in three patients (13.6%). The mean time to recovery was $4.5{\pm}1.8$ days for isolated thrombocytopenia, and $5.1{\pm}1.8$ days for PT and aPTT prolongation. Hematologic complications could occur suddenly 1?4 days after hospitalization. Among 35 patients with neurologic complications, dizziness was evident in 16 patients (45.7%), and diplopia / blurred vision in 19 patients (54.3%). The mean time to recovery was $3.4{\pm}0.6$ days in patients receiving anti-acetylcholine esterase and $6.9{\pm}1.8$ days in those not receiving anti-acetylcholine esterase (p=0.00). Conclusion: Occurrence rates of hematologic and neurologic complications following venomous snake bite differed as compared to other studies conducted in Korea. Onset of hematologic complications can occur rapidly days after admittance. Anti-acetylcholine esterase administration may be effective in treating neurologic complications.

Objective : In general, to perform posterior lumbar interbody fusion(PLIF), it has been used more invasive procedure than simple discectomy. However we try to perform PLIF with TFC with smaller invasion almost same as in simple discectomy. This study is about its procedure and clinical results. Materials and Methods : The authors retrospectively analyzed 43 cases of minimally invasive PLIF with TFC from July 1998 to May 2000. Operative procedure, operative complication, change of disc height, blood loss, ambulation time, hospitalization period, clinical success rate, and bony fusion rate were analyzed. Results : 40 patients were capable to walk on the 2nd day of the post-operation. The average hospitalization period is 5.6 days. The average blood loss was 0.19L/level with no transfusion or wound drainage. The height of disc changed from 8.84mm to 13.54mm. Clinical success rate is 95% when evaluated by the Prolo's scale. The complication was delayed wound infection(2) and transient paresthesis(1). The bony fusion was shown in 17 patients (94.4%) out of 18 patients who passed one year. Conclusion : As a result of minimally invasive PLIF, pain was decreased and early ambulation and short hospitalization was possible. Complication was similar or lower than other studies, and the bony fusion rate and clinical success rate were also similar during follow-up.

Objective: Although the incidence of chronic hepatitis B has decreased around the world due to widespread national preventative control measures, mortality from the same condition can increase if the condition leads to liver cancer or liver cirrhosis. In most cases, herbal medicine does not show any statistically significant effects related to liver damage, but preconceptions do exist that herbal medicine can be toxic and cause such liver damage. To investigate this situation, this study therefore investigated a patient with hepatitis B who had combined traditional Korean medicine therapy and the use of analgesic drugs during a hospitalization period.Method: A patient with hepatitis B was given combined traditional Korean medicine therapy and the use of analgesic drugs during a hospitalization period.Results: Within 26 days, the patient was free from liver damage during the hospitalization period. She was followed up with a liver function test and was discharged after her condition improved; she also reported decreased back pain.

The cost of medical treatment for motor vehicle accidents is increasing every year. In this study, we created a model to predict long-term hospitalization(more than 18 days) among minor patients, which is the main item of increasing traffic accident medical expenses, using five algorithms such as decision tree, and analyzed the factors affecting long-term hospitalization. As a result, the accuracy of the prediction models ranged from 91.377 to 91.451, and there was no significant difference between each model, but the random forest and XGBoost models had the highest accuracy of 91.451. There were significant differences between models in the importance of explanatory variables, such as hospital location, name of disease, and type of hospital, between the long-stay and non-long-stay groups. Model validation was tested by comparing the average accuracy of each model cross-validated(10 times) on the training data with the accuracy of the validation data. To test of the explanatory variables, the chi-square test was used for categorical variables.
