This study analyzed efficiency by utilizing DEA analytical technique centering on materials for 2009 of 20 major university hospitals in capital area. Input variables were utilized professor & full-time doctor, resident, nurse & number of bed hospitals. Output variables were analyzed by dividing number of annual outpatients & number of annual inpatients, and annually total outpatient profit & inpatient profit into a model of the standard for number of patients and the standard for medical profit. DEA analysis was elicited efficiency score by applying CCR, BCC, BFG, scale profit, and SE model. Through t-test after eliciting efficiency score, the implications were suggested by comparing efficiency between DMU in Seoul and DMU in capital area, by comparing between high-class general hospitals and general hospitals, and by comparing between high-class general hospitals in Seoul and 5 big hospitals. As a result of analysis, the major university hospitals in capital area showed high efficiency as a whole close to "1," but indicated low efficiency relatively in CCR field. Thus, the expansion in scale within capital area was indicated to reach the limit. Second, in a model of analyzing the standard for number of patients, the medical institutions, which are being operated efficiently, were indicated to be 10 DMUs. In the standard for medical profit, 12 DMUs were analyzed to be operated efficiently. Third, the efficiency in general hospital was higher than high-class general hospital. Thus, the efficiency of operation was indicated to be more important than scale. Also, large high-class hospitals(big 5) where are located in downtown Seoul showed the higher efficiency than other general high-class general hospitals, but were indicating very low efficiency in some DMUs. Fourth, as a result of generalizing and evaluating the number of patients and the medical profit, the efficient DMU was indicated to be more when analyzing on the basis of medical profit than the standard for number of patients. Thus, major university hospitals in capital area were indicated to make more effort for section in medical profit. Based on the analytical results of efficiency, a strategy for reinforcing efficiency in inefficient DMU was indicated to be needed a strategy of creating customers for promoting number of patients and a strategy for making operation efficient for increasing profitability.

Background: This study was designed to statistically analyze the year, gender, age, insurance type, and condition/disease of patients who were admitted to the Department of Acupuncture and Moxibustion Medicine at DaeJeon Korean Medicine Hospital over a 5-year period (2015-2020). Methods: Patients who visited the Department of Acupuncture and Moxibustion Medicine at DaeJeon Korean Medicine Hospital were classified according to year, gender, age, insurance type, and condition/disease. The statistical analysis was performed using IBM SPSS 23.0. Results: There is an increasing number of patients attending the Department of Acupuncture and Moxibustion Medicine year-on-year over the 5-year period, with a higher frequency of females than males each year. The largest age groups represented in these patients were those aged in their 50s, followed by those aged in their 40s, and 60s. Furthermore, the number of patients using health insurance was greater than those using automobile insurance each year. Of the 5,061 patients, the most common group was the patients (n = 991) who reported sprain and strain of cervical spine, followed by lumbar spine, lumbar herniation of the intervertebral disc, and facial paralysis. Conclusion: The number of patients seeking traditional Korean medicine treatment continues to increase, particularly in the 40s to 60s age group, with a larger proportion using health insurance and sprain or strain of the cervical spine. The results of this study may be used as a local (Daejeon) reference to develop Korean medicine policies, such as setting up medical benefits for patients using Korean medicine hospitals.

Purpose: The purpose of this study is to compare the toxicologic characteristics of two groups of patients with acute intoxication for two different time periods and to make recommendations based on the results of this study. Methods: We reviewed retrospectively the medical records of patients with acute intoxication in our emergency center from June 1997 to May 1998 (group A) and from June 2000 to May 2003 (group B), and we evaluated differences in the epidemiologic and the toxicologic characteristics between the two groups. Results: The ratios of the number of patients with acute intoxication to the total numbers of patients who visited our emergency department were $0.49\%$ and $0.52\%$ for groups A and B, respectively. In both groups many poisoned patients visited our emergency center from 4:00 pm to midnight. The interval between the time of intoxication and arrival at the hospital was significantly shorter in group B. The number of patients transferred to our emergency center was larger in group B. Attempted suicide was the major cause of acute intoxication in both groups. Major toxic substances in both groups were centrally active drugs and insecticides. The number of comatose and mechanically ventilated patients was larger in group B. However, there was no statistically significant difference in the mortality rates. Conclusion: Emergency physicians who manage intoxicated patients should recognize regional characteristics and differences in the toxicologic characteristics of poisoning. In addition, the establishment of a poisoning control center in the regional emergency center is necessary to integrate data control and to enhance specialized management of intoxicated patients.

Objectives By analyzing data of the pediatric patients who had visited the emergency room of the oriental medical hospital, we can understand their characteristics and diseases. The purpose of this study was to introduce the excellence of the Oriental medicine, to develop various treatments, and to revitalize pediatric emergency care at the oriental medical hospital. Methods The study was composed of 334 pediatric patients who had visited the emergency room of the ${\bigcirc}{\bigcirc}$ university oriental hospital from January 2011 to December 2013. Results 1. It has showed that between 7 to 12 years old patients (27.8%) were the most common age populations. 2. The number of pediatric patients was increased during February. According to the weekly distribution data, the number of pediatric patients who had visited on Sunday was the highest (28.7%). Also, the number of pediatric patients who had visited the ER between 21 to 24 hours (29.0%) was the highest. 3. The two major reasons for inpatient hospitalization were digestive and nerve-related symptoms. Nerve-related symptoms were the most common in infants while digestive symptoms were the most common in other child development stages. 4. The duration of time interval from the onset of symptoms to the ER visit was most commonly within 6 hours (50.3%). An acupuncture and herbal medication treatment (70.1%) were the most common medical treatments. The majority of the pediatric patients (95.5%) were discharged after their medical treatments. Conclusions A serious acute illness was not the most common reason for the ER visit among the pediatric patients. The most common disease states that have preferred to be treated with the oriental medicine were dyspepsia, crying, facial palsy, and ankle sprain. We have to introduce the excellence of the oriental medicine. We also need to try developing other treatments such as magnetic acupuncture, aromatherapy, and revitalizing pediatric emergency care at the oriental medical hospital.

This study was conducted to analyze patient days and medical care benefits of finger-amputated patients due to industrial accident. The 161 personal data on medical care for finger-amputated patients due to industrial accident(88 in 1994, 73 in 1995) of Regional Labor Office and hospital characteristics were analyzed. The major results of this study were as follows : According to stepwise multiple regression analysis of patient days, number of amputated finger, location of hospital, bed capacity of hospital, presence of plastic surgery in hospital, number of orthopedic specialist per 100 beds, sick leave benefits per day were the major significant variables in order. In stepwise multiple regression analysis with medical care benefits as a dependent variable, presence of plastic surgery in hospital, number of orthopedic specialist per 100 beds, number of amputated finger, sick leave benefits per day, age, bed capacity of hospital were the major significant variables in order. The minimum optimal size with the lowest medical care benefits was a hospital with 300 beds. This shows that the economy of scale is also applicable for hospital industry. In summary, presence of plastic surgery in hospital, number of orthopedic specialist per 100 beds, number of amputated finger, sick leave benefits per day, bed capacity of hospital were the major significant variables in both patient days and medical care benefits.

Purpose: Continuous intravenous access is imperative in emergency situations. Ultrasound-guided internal jugular vein (IJV) catheterization was investigated in critically ill pediatric patients to assess the feasibility of the procedure. Methods: Patients admitted to the pediatric intensive care unit between February 2011 and September 2012 were enrolled in this study. All patients received a central venous catheter from attending house staff under ultrasound guidance. Outcome measures included successful insertion of the catheter, cannulation time, number of cannulation attempts, and number and type of resulting complications. Results: Forty-one central venous catheters (93.2%) were successfully inserted into 44 patients (21 males and 23 females; mean age, $6.54{\pm}1.06$ years). Thirty-three patients (75.0%) had neurological disorders. The right IJV was used for catheter insertion in 34 cases (82.9%). The mean number of cannulation attempts and the mean cannulation time was $1.57{\pm}0.34$ and $14.07{\pm}1.91$ minutes, respectively, the mean catheter dwell time was $14.73{\pm}2.5$ days. Accidental catheter removal was observed in 9 patients (22.0%). Six patients (13.6%) reported complications, the most serious being catheter-related sepsis, which affected 1 patient (2.3%). Other complications included 2 reported cases of catheter malposition (4.6%), and 1 case each of arterial puncture (2.3%), pneumothorax (2.3%), and skin infection (2.3%). Conclusion: The results suggest that ultrasound-guided IJV catheterization can be performed easily and without any serious complications in pediatric patients, even when performed by visiting house staff. Therefore, ultrasound-guided IJV catheterization is strongly recommended for critically ill pediatric patients.

Purpose: On November 15, 2012, sales of OTC (Over-The-Counter) drugs began at convenience stores, which changed the accessibility of some drugs. As a result, the exposure and access patterns of these drugs could have changed. In this study, we reviewed the changes in the characteristics of drug poisoning patients because of the reposition of nonprescription drugs according to the revised Pharmaceutical Affairs Act. Methods: A retrospective study was conducted to evaluate changes in characteristics of drug poisoning patients between 2008 and 2016. A registry was developed by an emergency medical center in a local tertiary teaching hospital, and patients who visited the center were enrolled in this registry. We compared two periods, from 2008 to 2012 (Pre OTC) and from 2013 to 2016 (Post OTC), for type of intoxicant, time from poisoning to visiting the emergency center, intention, psychiatric history, previous suicidal attempt, alcohol status, and emergency room outcomes. The primary outcome was the number of patients who took acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Secondary outcomes were ICU admission rate, mortality rate, and number of patients who visited the ER when the pharmacy was closed after taking acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Results: Among 1,564 patients, 945 and 619 patients visited the emergency room during pre and post OTC periods. The number of patients with acetaminophen and NSAIDs poisoning decreased from 9.2% to 6.1% (p=0.016). The ICU admission rate and mortality rate in the emergency room did not show significant results in the relevant patient groups, and so was the number of patients visiting ER when the pharmacy was closed taking acetaminophen and NSAIDs. Conclusion: Despite the sales of nonprescription drugs at convenience stores, the number of acetaminophen and NSAIDs poisoning patients decreased.

Background: The increasing incidence of multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) has become a serious worldwide problem. However, there is insufficient data regarding the current status of MDR-TB and XDR-TB in Korea. This study examined the recent status of MDR- and XDR-TB using the data from 7 laboratories, in which almost all drug susceptibility tests (DST) for Mycobacterium tuberculosis were performed. Methods: The patients' identification data and DST results were collected from all 7 laboratories from 2001 to 2006 and the number of patients with MDR-TB and XDR-TB were calculated. Results: The number of DSTs was 140,638 for 6 years with an increasing incidence each year (p<0.001). The number of DST with MDR results was 18,510 and personal identifying information was obtained in 16,640 (89.9%) tests. The number of MDR-TB patients from 2001 to 2006 was 2,329, 2,496, 2,374, 2,300, 2,354, and 2,178, respectively, when counting the duplications in a year as one patient. The number of MDR-TB patients when counting the duplications in 6 years as one patient was 2,281, 1,977, 1,620, 1,446, 1,512, and 1,373, respectively. When the same method was adopted, the number of XDR-TB patients was 191, 238, 282, 260, 272, and 264, respectively, and 189, 150, 130, 90, 122, and 110 patients, respectively. Conclusion: Despite the national efforts to control TB, there are still a large number of MDR- and XDR-TB patients in Korea.

In Korea, elderly population aged 65 and older are about 5.0% and 10.7% in 1990 and 2009, respectively. Since elderly people may experience physiologic changes with aging and their pharmacodynamic and pharmcokinetic parameters also have been undergone changes, several adverse drug reactions can occur more frequently than young people. Especially, neuropsychiatric adverse drug reactions such as delirium and drowsiness endanger elderly patients more. The purpose of this study is to evaluate the outpatient prescriptions using drug causing delirium and drowsiness in elderly patients aged 65 and older. We retrospectively reviewed prescriptions for elderly patients collected from four community pharmacies from January 2nd to February 1st, 2010. One pharmacy was located closed to a general hospital, and others were located closed to a internal medicine or an ENT clinic. The each number of the collected prescriptions was followings; Group A (n=496) from internal medicine department of a general hospital; Group B (n=44) from ENT department of general hospital; Group C (n=144) from internal medicine clinic; Group D (n=110) from ENT clinic. In result, in Group A, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.38 In Group B, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.09 In Group C, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.51. In Group D, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.72. Especially, in Group D, the percentage of prescription that drugs causing delirium or drowsiness per Rx prescribed more than 3 is 52.73% In all the 4 groups, over the 60% of drugs causing delirium and/or drowsiness per prescription of elderly patients were prescribed. It means elderly patients take 2 drugs causing delirium and/or drowsiness among 3 drugs, which is very serious. Frequently prescribed drugs causing delirium and/or drowsiness were followings; GI agents, antitussives & expectorants, histamine H1 antagonist, analgesics, antibiotics. Among these drugs, GI agents was high raking in all the 4 groups, and pharmacists should caution elderly patients when counseling. In the internal medicine groups (Group A,C), drugs concerning chronic diseases were prescribed frequently. In conclusion, pharmacist's role is important. Pharmacists are well informed of the drugs causing delirium or drowsiness and it is important to explain about ADRs slowly and easily to the elderly patients that receive drugs causing delirium or drowsiness. And institutional device is needed. For example, when doctors prescribe drugs for the elderly patients, message is needed that supply some informations about drugs causing delirium or drowsiness.
