Purpose: As the National Health Insurance Service (NHIS) began to cover home oxygen therapy (HOT) services from 2006, it is expected that the new services have contributed to overall positive outcome of patients with chronic obstructive pulmonary disease (COPD). We examined whether the usage of HOT has helped slow down the progression of COPD. Methods: We examined hospital claim data (N=10,798) of COPD inpatients who were treated in 2007~2012. We performed ${\chi}^2$ tests to analyze the differences in the changes to respiratory impairment grades. Multiple logistic regression analysis was used to identify factors that are associated with the use of HOT. Finally, a generalized linear mixed model was used to examine association between the HOT treatment and changes to respiratory impairment grades. Results: A total of 2,490 patients had grade 1 respiratory impairment, and patients with grades 2 or 3 totaled 8,308. The OR for use of HOT was lower in grade 3 patients than others (OR: 0.33, 95% CI: 0.30~0.37). The maintenance/mitigation in all grades, those who used HOT had a higher OR than non-users (OR: 1.41, 95% CI: 1.23~1.61). Conclusion: HOT was effective in maintaining or mitigating the respiratory impairment in COPD patients.

The incidence, type and distribution of polyneuropathy in patients with chronic obstructive pulmonary disease (COPD) were assessed and also analyzed the causative factors. Forty-four patients, mean age 66.1 years (42 male, 2 female), have been investigated with arterial gas analysis, pulmonary function test, clinical and electrodiagnostic studies. None of them had conditions known to affect the peripheral nervous system such as metabolic disorders or drugs. In a selected group of 44 patients, electrophysiological findings of polyneuropathy were found in 22 patients(50%), clinical polyneuropathy were diagnosed in 13 patients(9 patients were diagnosed by electrophysiological studies, 4 patients were normal by electrophysiological studies). These findings indicate that subclinical polyneuropathy(13 patients, 30%) more commonly occurs than clinical polyneuropathy(9 patients, 20%) in associated with COPD. In the patients with polyneuropathy, the lesions were predominant axonal degeneration, the changes were more involved in leg than arm, more frequently affected sensory fibers. We could not find etiologic factor to cause polyneuropathy in COPD patients.

Purpose: This study was conducted to develop and test an explanatory model on functional capacity in patients with chronic obstructive pulmonary disease using path analysis. Methods: Data were collected from 149 chronic obstructive pulmonary disease patients using 6-minute walk test, measurement of oxygen saturation, pulmonary function test, and self-reported questionnaires from June to October, 2005. The collected data were analyzed using SPSS/WIN 12.0 program and AMOS/WIN 4.0 program. Results: The overall fitness indices of modified model were good($x^2$ = 14.324, p = .281 GFI = .981, RMSEA = .006, AGFI = .944, NFI = .927, NNFI = .999, CFI = .999, PNFI = .613, $x^2$/df = 1.194). Functional capacity was influenced directly by age(${\beta}$ = -.304, p = .000), dyspnea(${\beta}$ = -.278, p = .000), self-efficacy(${\beta}$ = .240, p = .000), social support(${\beta}$ = .175, p = .004), pulmonary function(${\beta}$ = .169, p = .008), and oxygen saturation(${\beta}$ = .099, p = .048). These variables explained 39.3% in functional capacity. Conclusion: The findings of this study suggest that comprehensive nursing interventions should focus on decreasing dyspnea and increasing self-efficacy, social support, and oxygen saturation. In this perspective, pulmonary rehabilitation would be an effective strategy for improving functional capacity in patients with chronic obstructive pulmonary disease.

Purpose: This study seeks to examine prevalence, risk factors, and quality of life of Korean adults with Chronic Obstructive Pulmonary Disease (COPD). Methods: From the database of the Fourth Korean National Health and Nutrition Examination Survey (KNHANES IV-1, 2008), the researchers selected 1,458 adults over the age of 45. The original study was a population-based epidemiological survey of health and nutrition with a stratified multistage clustered probability design. Prevalence of COPD was computed on the basis of the sampling weight. Data were analyzed using descriptive statistics, ${\chi}^2$ test, t-test and multiple logistic regression with the SPSS WIN 18.0 and SAS Ver. 9.1 program. Results: The prevalence of COPD was 18.0% among people older than 45 yr. The prevalence of current smokers was 19.7% in this population and 26.3% in individuals with COPD. Age, gender, education, and smoking levels were found to be risk factors for COPD. Significant difference in quality of life was founded between adults with COPD and the healthy controls. Conclusion: The results of this study indicate that COPD is a highly prevalent disease in Korea. To reduce the prevalence of COPD and improve health-related quality of life in patients with COPD, nursing interventions must focus on prevention of risk factors.

Purpose: The purpose of this study was to examine descriptors of dyspnea and clinical characteristics in patients with COPD at ED visit. Method: The study design was a descriptive survey, and 46 patients with COPD complaining of dyspnea were participated during their visits to the ED of C university hospital in G city, from October 1, 2004 to April 8, 2005. Result: The qualitative characteristics of dyspnea at the time of decision to the ED visit were short of breath (71.7%), tight (32.6%), hard to breathe (15.2%), smothering or suffocating (10.9%), gasping (8.7%), couldn't breathe (6.5%), constricted (2.2%), and hunger for air (2.2%). In the item of dyspnea checklists, My chest felt tight was the most common description among subjects. As the result of factor analysis of dyspnea checklists, the first factor was characterized rapid and shallow, the second was suffocating/smothering, the third was hunger for air, and the fourth was constricted. Conclusion: This study suggests that a checklist of dyspnea descriptors based on this findings would be utilized as a tool of initial and ongoing assessment for dyspneic patients with COPD in the ED after identifying the validity and reliability of the checklist.

Purpose: This study was conducted to explore the mediating effect of nutritional status on the relationship between symptom experience and functional status of patients with Chronic Obstructive Pulmonary Disease (COPD). Methods: A total of 141 COPD patients visiting D hospital and I hospital in B city were enrolled in this study. Data were collected from January 2017 to July 2017. Outcome variables were measured by Mini Nutritional Assessment Short-Form (MNA-SF) for nutritional status, The Memorial Symptom Assessment Scale (MSAS) for symptom experience, and The Functional Performance Inventory Short Form (FPI-SF) for functional status. The data were analyzed with descriptive statistics, Pearson's correlation, and path analysis using SPSS/WIN 21.0 and AMOS 25. Results: There was a significant negative correlation between symptom experience and nutritional status (r=-.61, p<.001), a significant negative correlation between symptom experience and functional status (r=-.40, p<.001), and significant positive correlation between nutritional status and functional status (r=.47, p<.001). Symptom experience had indirect effects on functional status through nutritional status. Conclusion: For enhancing functional status in COPD patients, it is necessary to develop nursing intervention programs to enhance symptom management as well as nutritional status.

Purpose: This study was done to investigate the correlation among symptom experience, self-efficacy, depression, and medication adherence in patients with chronic obstructive pulmonary disease (COPD). Methods: Participants were 100 patients with COPD recruited in one general hospital in Seoul. A structured questionnaire was used to measure the study variables. Data were analyzed using descriptive statistics, t-test, ANOVA, and Spearman correlation coefficient. Results: Symptom experience and depression were positively correlated (r=.41, p<.001), symptom experience and self-efficacy were negatively correlated (r=-.21, p=.035). Depression was negatively correlated with self-efficacy (r=-.60, p<.001) and medication adherence (r=-.48, p<.001). Self-efficacy and medication adherence were positively correlated(r=.76 p<.001). Conclusion: Findings from this study indicate that depression and self-efficacy are important variables related to medication adherence in patients with chronic obstructive pulmonary disease. Therefore, depression and self-efficacy should be assessed, and customized nursing interventions should be provided in order to increase medication adherence.

Background: Nocturnal hypoxemia occurs in patients with chronic obstructive pulmonary disease(COPD) and the detection and treatment of nocturnal hypoxemia should be part of the management of COPD patients. We performed this study to evaluate the factors influencing to sleep related arterial oxygen desaturation($SaO_2$) in patients with COPD. Methods: Resting and exercise cardiopulmonary function test, polysomnography, and $SaO_2$ during resting, exercise and sleep were measured in 12 patients with COPD. Results: The $SaO_2$ fell twice as much during sleep as during maximal exercise($13.1{\pm}9.3%$ fall in nocturnal $SaO_2$ vs. $6.4{\pm}3.3%$, p<0.05). Fall in nocturnal $SaO_2$ was well correlated with mean exercise $SaO_2$(r=-0.78, p<0.05), minimum exercise $SaO_2$(r=-0.90, p<0.01), and resting $SaO_2$(Cr=-0.82, p<0.05). Lowest sleep $SaO_2$ was well correlated with mean exercise $SaO_2$(r=0.80, p<0.05), lowest exercise $SaO_2$(r=0.90, p<0.01), and resting $SaO_2$(r=0.84, p<0.05). Conclusion: Resting and exercise $SaO_2$ was well correlated with nocturnal $SaO_2$, but exercise study add no additional information to predicting the nocturnal oxygen desaturation in patients with COPD.
