Factors affecting health status in patients with chronic obstructive pulmonary disease

Abstract

The aim of this study is to determine the correlation between the quality of life (QOL) and subjective dyspnoea, subjective fatigue, sleep quality, and the forced expiratory volume in first second (FEV(1)) % predicted value and collective contribution of these variables on QOL. The study was conducted with 102 patients. Pulmonary function tests (FEV(1) % predicted value, FEV(1) /forced vital capacity), subjective dyspnoea, subjective fatigue, sleep quality were assessed. There were negative correlations between QOL total score and pulmonary function tests, positive correlations between QOL total score and subjective dyspnoea score, subjective fatigue and sleep quality total scores. In addition, subjective dyspnoea, subjective fatigue and sleep quality total scores and FEV(1) % predicted value accounted for 68.1% of the variance on QOL. As a conclusion of these findings, it has been recommended that these variables should be considered when planning an approach towards improving the QOL in chronic obstructive pulmonary disease patients.

Effect of Implementing an Educational Module About Inhaler Use on Severity of Dyspnea and Adherence to Inhalation Therapy Among Patients with Chronic Obstructive Pulmonary Disease

“…This result is near the results of Akinci and Yildrin (2013) [33] who found that the mean years of disease duration for their sample was 9.1±8.5 years.…”

“…These percentages are less than the percentage of Salah et al, (2013) and Akinci and Yildrin (2013) who stated that most of their sample was male [30,33]. This may be due to the lower sample size of the current study in relation to their sample size.…”

The relation between self‐efficacy in patients with chronic obstructive pulmonary disease and caregiver burden

“…Another factor for caregiver needs of patients with COPD is reduction in physical activity resulting from increased severity of the disease (9). Therefore, the patients have difficulty in fulfilling their daily life activities (8,(18)(19)(20). In a study by T€ urk and € Ust€ un, with progression of COPD, advanced age and chronic diseases, the patients were found to become more dependent.…”

Determinants of 1‐year changes in disease‐specific health status in patients with advanced chronic obstructive pulmonary disease: A 1‐year observational study

“…Previous studies have shown that baseline characteristics such as male gender, older age, lower level of education, lower body weight, more respiratory symptoms, severe airflow limitation, and symptoms of anxiety and depression are related to deterioration in generic and disease‐specific health status in patients with COPD . In addition, frequent exacerbations during follow‐up have been shown to be related to deterioration in disease‐specific health status .…”

“…6 Previous studies have shown that baseline characteristics such as male gender, older age, lower level of education, lower body weight, more respiratory symptoms, severe airflow limitation, and symptoms of anxiety and depression are related to deterioration in generic and disease-specific health status in patients with COPD. [7][8][9][10][11][12] In addition, frequent exacerbations during follow-up have been shown to be related to deterioration in diseasespecific health status. 13 Previous authors suggested that the rate of decline in forced expiratory volume in the first second (FEV 1 ) is related to the rate of increase in St George's Respiratory Questionnaire (SGRQ) score.…”
