“…In a relatively small study of 130 COPD patients, LIM et al [13] found three clusters of symptoms, two of which were in line with our factors. Their respiratory-functional cluster with dyspnoea, physical functioning and dry mouth resembled our respiratory symptoms factor, and their mood cluster with depression and anxiety was similar to our emotional factor.…”

“…It seems, that the number and composition of symptom clusters varies between different studies, possibly due to the heterogeneity of the study populations. Symptom factors in lung cancer, COPD and IPF were, however, comparable to one another [13,16,17]. Respiratory and mental symptom factors seem to be dominant, which is probably due to the major impact of respiratory symptoms in lung diseases and the emotional burden of a severe life-limiting disease.…”

“…By extension, we defined a symptom factor as a cluster of symptoms connected by an underlying variable. Clustering of symptoms has been studied in advanced cancer [11,12], COPD [13], asthma [14], sleep apnoea [15] and lung cancer [16,17]. To the best of our knowledge, despite a high symptom burden in IPF, no studies on symptom clustering in IPF have been published.…”

Factor analysis identifies three separate symptom clusters in idiopathic pulmonary fibrosis

BackgroundIdiopathic pulmonary fibrosis (IPF) is a severe and progressive lung disease with a poor prognosis. Patients with IPF suffer from a high symptom burden, which impairs their health-related quality of life (HRQoL). Lack of research on IPF symptoms and their clustering, however, makes symptom-centred care challenging.MethodsWe sent two questionnaires, RAND 36-Item Health Survey and Edmonton Symptom Assessment System, to 300 patients from the FinnishIPF registry. Of the 300 patients, 245 (82%) responded. We performed an exploratory factor analysis on the results to search for potential clustering of symptoms into factors.ResultsWe found three distinct symptom factors: the emotional factor (including depression, anxiety, insomnia, loss of appetite and nausea), the pain factor (pain at rest or in movement) and the respiratory symptoms factor (shortness of breath, cough, tiredness and loss of wellbeing). Correlation was strong within the factors (ρτ 0.78–0.85) and also evident between them. The factors correlated with the different dimensions of HRQoL: the emotional factor with mental health (correlation coefficient=−0.69) and vitality (−0.63), the pain factor with bodily pain (−0.72) and the respiratory symptoms factor with vitality (−0.69), general health (−0.64) and physical functioning (−0.62).ConclusionWe found three distinct symptom factors in IPF, of which respiratory and emotional factors showed the strongest association with decreasing HRQoL. Routine assessment of IPF patients' respiratory symptoms, mental health and pain are important as these may be linked with other symptoms and significantly impair the patient's HRQoL.

“…Regular exercises and participation in leisure and social activities have close relationship with enhanced life satisfaction in the elderly. Additionally, approaches and interventions based on symptom clusters have greater effect on quality of life than programs customized to a single individual [ 29 ]. Having these prior studies as the background, the participants who participated in a respiratory program with their peers encouraged each other to persist in participation, and the process of learning a new instrument gave them a sense of accomplishment and an opportunity to let others know about their abilities.…”

BackgroundPhysical changes due to aging lead to weakening of respiratory muscles and decreased lung functions that result in increasing risk of chronic respiratory disease. A complex respiratory rehabilitation program is needed to prevent respiratory diseases and improve lung functions and quality of life. The purpose of the present study was to examine the effects of respiratory training programs on pulmonary functions, cardiovascular endurance, and quality of life in elderly women.Material/MethodsThe program was structured with respiration exercise and playing wind musical instruments for 10 weeks (n=13) and 5 weeks (n=16), respectively, for elderly women in 2 different community welfare centers. The program consisted of breathing exercises twice a week, 20 min per session, and 40 min of wind instrumentation. Effects were assessed using forced vital capacity (FVC), forced expiratory volume-one second (FEV1), FEV1/FVC ratio (FEV1%), maximum voluntary ventilation (MVV), 6-minute walk test (6MWT), modified Borg scale (MBS), and life satisfaction scale (LSS).ResultsThe 10-week program group (10WPG) showed significant differences in FVC, MVV, 6MWT, MBS, and LSS before and after interventions (p<.05), and the 5-week program group (5WPG) showed significant differences in FVC and 6MWT. MVV, MBS, and LSS were not significantly different between the 2 groups (p<.05).ConclusionsThis study confirms that the long-term respiration training program has positive effects on pulmonary functions, cardiopulmonary endurance, and quality of life. Various respiratory training programs and long-term implementations are needed to prevent respiratory illness and to improve lung functions and quality of life of respiratory patients.

Background: Health-related quality of life is an important outcome variable with COPD patients. Impaired health-related quality of life among COPD patients is closely related to various factors. There are many factors that predict the HRQoL and the correlation with other important variables. Predictors of health-related quality of life were debatable in the literature. Aim: This review aimed to describe the correlation with HRQoL and to explore the predictors of HRQoL among patients with COPD. Methods: An integrative review method was conducted. A search protocol was conducted using EBSCO, Pubmed, CINAHL, Ovid, ProQuest, Cochrane, and Google Scholar databases up to October 1, 2019. Results: The review results out of 30 articles that discuss the predictors of HRQoL and 22 articles that discuss the HRQoL correlations with other important variables. The HRQoL predictors are classified according to sociodemographic factors and clinical factors, and also, the correlation and prediction of HRQoL with anxiety, fatigue, and uncertainty. The results of this review showed controversies in predictors between the studies. The most retrieved predictors were age, educational level, comorbidities, socioeconomic status, FEV1% predicted, GOLD stages, and the number of hospitalizations. The variables of anxiety and fatigue were strongly correlated and predicted HRQoL. While uncertainty was not reported as a significant HRQoL predictor. Conclusion: This review provides support about reliable predictors than unreliable one although some predictors still need further research in different races and cultures. Future research is needed to explore whether uncertainty can predict HRQoL among patients with COPD.
