Many findings suggest that chronic obstructive pulmonary disease (COPD) imposes an enormous burden on patients, health-care professionals and society. COPD contributes to morbidity and mortality and to a significant use of health-care resources. In spite of a higher prevalence of COPD in Korea, the result of COPD treatment is not effective. The purpose of this article was to review recent advances in the study of COPD in Korea with the aim of improving effective management. This review highlights articles pertaining to the following topics; prevalence, assessment of COPD, risk factors for hospitalization, co-morbid diseases, phenotypes, and treatment issues.

The study was conceived in relation to a concern over the growing gap between the needs of chronic patients and the availability of care from the current health care system in Korea. Patients with agonizing chronic pain, discomfort, despair and disability are left with helplessly unprepared families with little help from the acute care oriented health care system after discharge from hospital. There is a great need for the development of an alternative means of quality care that is economically feasible and culturally adaptible to our society. Thus, the study was designed to demonstrate the effectiveness of home heath care as an alternative to bridge the existing gap between the patients' needs and the current practice of health care. The study specifically purports to test the effects of home care on health expenditure, readmission, job retention, compliance to health care regime, general conditions, complications, and self-care knowledge and practices. The study was guided by the operations research method advocated by the Primary Health Care Operations Research Institute(PRICOR) which constitutes 3 stages of research : namely, problem analysis solution development, and solution validation. The first step in the operations research was field preparation to develop the necessary consensus and cooperation. This was done through the formation of a consulting body at the hospital and a steering committee among the researchers. For the stage of problem analysis, the Annual Report of Seoul National University Hospital and the patients records for last 5 years were reviewed and selective patient interviews were conducted to find out the magnitude of chronic health problems and areas of unmect health care needs to finally decide on the kinds of health problems to study. On the basis of problem analysis, the solution development stage was devoted to home care program development asa solution alternative. Assessment tools, teaching guidelines and care protocols were developed and tested for their validity. The final stage was the stage of experimentation and evaluation. Patients with liver diseases, hemiplegic and diabetic conditions were selected as study samples. Discharge evaluation, follow up home care, measurement and evaluation were carried out according to the protocols of care and measurement plan for each patient for the period of 6 months after discharge. The study was carried out for the period from Jan. 1987 to Dec. 1989. The following are the results of the study presented according to the hypotheses set forth for the study ; 1. Total expenditures for the period of study were not reduced for the experimental group, however, since the cost per hospital visit is about 4 times as great as the cost per home visit, the effect of cost saving by home care will become a reality as home care replaces part of the hospital visits. 2. The effect on the rate of readmission and job retention was found to be statistically nonsignificant though the number of readmission was less among the experimental group receiving home care. 3. The effect on compliance to the health care regime was found to be statistically significant at the 5% level for hepatopathic and diabetic patients. 4. Education on diet, rest and excise, and medication through home care had an effect on improved liver function test scores, prevention of complications and self - care knowledge in hepatopathic patients at a statistically significant level. 5. In hemiplegic patient, home care had an effect on increased grasping power at a significant level. However. there was no significant difference between the experimental and control groups in the level of compliane, prevention of complications or in self-care practices. 6. In diabetic patients, there was no difference between the experimental and control groups in scores of laboratory tests, appearance of complications, and self-care knowledge or self -care practices. The above findings indicate that a home care program instituted for such short term as 6 months period could not totally demonstrate its effectiveness at a statistically significant level by quantitative analysis however, what was shown in part in this analysis, and in the continuous consultation sought by those who had been in the experimental group, is that home health care has a great potential in retarding or preventing pathological progress, facilitating rehabilitative and productive life, and improving quality of life by adding comfort, confidence and strength to patients and their families. For the further studies of this kind with chronic patients it is recommended that a sample of newly diagnosed patients be followed up for a longer period of time with more frequent observations to demonstrate a more dear- cut picture of the effectiveness of home care.

Purpose: The purpose of this study is investigation of clinical and functional outcomes in homogeneous group with positive culture after arthroscopic management for pyogenic knee arthritis and analysis of factors affecting those outcomes. Materials and Methods: Thirty-two patients with positive culture after arthroscopic management were included. Mean follow-up period was 41.6 months. Clinical evaluation included death related to infection, recurrence, time to normalize erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), duration of administration of intravenous antibiotics and readmission. Radiographic evaluation was performed according to Kellgren and Lawrence. The prevalence of total knee arthroplasty was investigated and functional evaluation included modified Lysholm, Tegner activity and Korean version of the Western Ontario and McMaster Universities (K-WOMAC) score. Results: Staphylococcus aureus was identified in 21 patients. Time to normalize ESR and CRP was 78.0 and 67.6 days, respectively. Two patients died while there were six recurrences and five readmissions. Rate of recurrence was significantly high in patients with chronic renal failure (P=0.034) and incidence of readmission was associated with higher radiographic grade of osteoarthritis and rate of reoperation (P=0.032 and P=0.006, respectively). At the final follow-up, radiographic grade worsened in 21 patients and was associated with those at first visit. Five arthroplasties were performed. Average modified Lysholm score, Tegner activity score and K-WOMAC score were 53.5, 2.7, 44.2 points, respectively. Conclusion: The severity of osteoarthritis on final radiographs was associated with those at first visit. Patients with higher grade of osteoarthritis at first visit showed higher incidence of readmission and those with chronic renal failure demonstrated higher chances of recurrence.

Background Sternal rigid plate fixation (RPF) has been adopted in recent years in high-risk cases to reduce complications associated with steel wire cerclage, the traditional approach to sternal closure. While sternal RPF has been associated with lower complication rates than wire cerclage, it has its own complication profile that requires evaluation, necessitating a critical examination from a national perspective. This study will report the outcomes and associated risk factors of sternal RPF using a national database. Methods Patients undergoing sternal RPF from 2005 to 2016 in the American College of Surgeons-National Surgical Quality Improvement Program were identified. Demographics, perioperative information, and complication rates were reviewed. Logistic regression analysis was performed to identify risk factors for postoperative complications. Results There were 381 patient cases of RPF identified. The most common complications included bleeding (28.9%), mechanical ventilation >48 hours (16.5%), and reoperation/readmission (15.2%). Top risk factors for complications included dyspnea (odds ratio [OR], 2.672; P<0.001), nonelective procedure (OR, 2.164; P=0.010), congestive heart failure (OR, 2.152; P=0.048), open wound (OR, 1.977; P=0.024), and operating time (OR, 1.005; P<0.001). Conclusions Sternal RPF is associated with increased rates of three primary complications: blood loss requiring transfusion, ventilation >48 hours, and reoperation/readmission, each of which affected over 15% of the study population. Smokers remain at an increased risk for surgical site infection and sternal dehiscence despite RPF's purported benefit to minimize these outcomes. Complications of primary versus delayed sternal RPF are roughly equivalent, but individual patients may perform better with one versus the other based on identified risk factors.

In order to prevent unnecessary re-admission, it is necessary to intensively manage the groups with high probability of re-admission. For this, it is necessary to develop a re-admission prediction model. Two - year discharge summary data of one university hospital were collected from 2016 to 2017 to develop a predictive model of re-admission. In this case, the re-admitted patients were defined as those who were discharged more than once during the study period. We conducted descriptive statistics and crosstab analysis to identify the characteristics of rehospitalized patients. The re-admission prediction model was developed using logistic regression, neural network, and decision tree. AUC (Area Under Curve) was used for model evaluation. The logistic regression model was selected as the final re-admission predictive model because the AUC was the best at 0.81. The main variables affecting the selected rehospitalization in the logistic regression model were Residental regions, Age, CCS, Charlson Index Score, Discharge Dept., Via ER, LOS, Operation, Sex, Total payment, and Insurance. The model developed in this study was limited to generalization because it was two years data of one hospital. It is necessary to develop a model that can collect and generalize long-term data from various hospitals in the future. Furthermore, it is necessary to develop a model that can predict the re-admission that was not planned.

Background: A time course analysis was undertaken to evaluate how perioperative process-of-care and outcome measures evolved after implementation of an enhanced recovery after thoracic surgery (ERATS) program. Methods: Outcome and process-of-care measures were compared between patients undergoing major elective thoracic surgery during a 9-month pre-ERATS implementation period to those at 1-3, 4-6, and 7-9 months post-ERATS implementation. Outcome measures included length of stay, the 30-day readmission rate, 30-day emergency department visits, and minor and major adverse events. Process measures included first time to activity, out-of-bed, ambulation, fluid diet, diet as tolerated, as well as removal of the first and last chest tube, epidural, patient-controlled analgesia, and Foley and intravenous catheters. Results: In total, 704 patients (352 pre-ERATS, 352 post-ERATS) were included. Mobilization-related process measures, including time to first activity (16.5 vs. 6.8 hours, p<0.001), out-of-bed (17.6 vs. 8.9 hours, p<0.001), and ambulation (32.4 vs. 25.4 hours, p=0.04) saw statistically significant improvements by 1-3 months post-ERATS implementation compared to pre-ERATS. Time to Foley removal improved by 4-6 months post-ERATS (19.5 vs. 18.2 hours, p=0.003). Outcome measures, including the 30-day readmission rate and emergency department visits, steadily decreased post-ERATS. By 7-9 months post-ERATS, both minor (18.2% vs. 7.9%, p=0.009) and major (13.6% vs. 4.4%, p=0.007) adverse events demonstrated statistically significant improvements. Length of stay trended towards improvement from 6.2 days pre-ERATS to 4.8 days by 7-9 months post-ERATS (p=0.06). Conclusion: The adoption of ERATS led to improvements in multiple process-of-care measures, which may collectively and gradually achieve optimization of clinical outcomes.

The first case was a 20 year old female who has been suffered from epigastric pain, and anorexia for 2 years. A thumb tip sized pulsion diverticulum 4cm above the esophagocardial junction was elicited by esophagogram and on exploration. A diverticulectomy with long esophagocardiomyotomy was performed. The second case was a 30 year old house wife who has had postprandial epigastric pain for 2 months accompained with frequent vomiting. Fiberscopy and esophagogram showed epiphrenic diverticulum of the esophagus. Same operative procedures were carried out and obtained a good result as first case. The third case was a 55 year old house wife who was admitted to this Chest Surgery Department because of regurgitation and intermittent vomiting for approximately 3 months. Esophagogram showed a large epiphrenic diverticulum of the esophagus. On exploration, a tennis ball sized pulsion diverticulum was found on the anterolateral wall of the esophagus. A partial esophagectomy including the diverticulum and esophagoesophagostomy was performed. The specimenshowed some erosive changes of the mucosal surface of the diverticulum and also the esophagus suggestive of diverticulitis and esophagitis. She has been satisfactory result until 4 months postoperatively, when she developed regurgitation and epigastric pain. Esophagogram showed stenosis of the operative site. Readmission and esophageal dilatations were done and improved without any problem. Epiphrenic or supradiaphragmatic diverticulum of the esophagus is a rare condition. Pathophysiologically, the conditions accompanied the spasm of the esophagus, many authors prefered the procedures of a diverticulectomy plus long esophagocardiomyotomy rather than simple diverticulectomy or esophagectomy and esophagoesophagostomy. Here we report the cases and reviewed the literatures.

Purpose: This descriptive study was to investigate the quality of life in patients with hematopoietic stem cell transplantation (HSCT) from June 1 to October 13, 2007. Method: The survey was conducted in 6 different university hospitals which located in Seoul and Jeollanam-do province using the Functional Assessment of Cancer Therapy-BMT Scale (FACT-BMT) version 4. We collected a total of 155 questionnaires and analyzed 149 among them. Results: The average score of quality of life was 2.53 out of 5. Physical well being score was highest among sub-domains, followed by emotional well-being, additional concerns, social/family well-being, and functional well-being. Study subjects worried that their conditions would get worse. However study subjects didn't regret having been received HSCT. Age, duration from HSCT, age at diagnosis, income, readmission, HSCT type, educational background, marital status, and the level of activities of daily living were related to quality of life. Conclusions: The findings of this study indicates that the HSCT survivor's quality of life issue is still important and have to be investigated repeatedly in the future. That is necessary for generalizing QOL outcomes for clinical use. We also suggest to develop interventions to improve QOL.

Purpose: The purpose of this study was to identify the attributes, antecedents, and consequences of post-intensive care syndrome. Methods: The study was conducted in accordance with Walker and Avant's conceptual analysis process. We searched the Medline, ProQuest, Google scholar, NANET (Korean National Assembly Library), and RISS (Korean Education and Research Information Service) databases resulting in 29 studies for in-depth review. Results: The attributes of post-intensive care syndrome include (1) new or worsening impairment persisting after discharge, (2) physical impairment, (3) psychological impairment, (4) cognitive impairment, and (5) symptom experience. The antecedents of the concept include a critical condition that requires intensive care, stressful events, immobility, sedation, delirium, insomnia, frailty, and invasive procedures. The consequences of post-intensive care syndrome are increased dependency in activities of daily life, decreased social interaction, delayed return to previous occupation, decreased quality of life, familial post-intensive care syndrome, and readmission/death. Conclusion: The concept of post-intensive care syndrome has multifaceted and integrative features. Further research needs to be conducted to develop a measurement tool that reflects the attributes of the concept and to develop multidisciplinary interventions to prevent post-intensive care syndrome.
