BACKGROUND This study assessed the adherence profiles to inhaled therapies and the agreement between two patient self-report adherence methods in stable COPD lpatients from seven Latin American countries. METHODS This observational, cross-sectional, multinational, multicenter study involved 795 COPD patients (post-bronchodilator forced expiratory volume in 1 second/forced vital capacity [FEV1...

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disorder. COPD patients may have different clinical features, imaging characteristics and natural history. Multiple studies have investigated heterogeneity using statistical methods such as unsupervised clustering to define different subgroups of COPD based largely on clinical phenotypes. Some studies have performed clustering usin...

INTRODUCTION Chronic obstructive pulmonary disease (COPD), characterized by a progressive deterioration of lung function caused primarily by the inhalation of toxic substances, is a leading cause of morbidity and mortality worldwide. Current treatment options for the management of its symptoms include the use of bronchodilators and glucocorticoid agents that are not universally beneficial and w...

There is need for a validated short, simple instrument to quantify chronic obstructive pulmonary disease (COPD) impact in routine practice to aid health status assessment and communication between patient and physician. Current health-related quality of life questionnaires provide valid assessment of COPD, but are complex, which limits routine use. The aim of the present study was to develop a ...

INTRODUCTION The clinical course of asthma and chronic obstructive pulmonary disease (COPD) is influenced by the co-occurrence of other chronic diseases and their pharmacotherapy. There are no data associated with the doctors' pharmacotherapy preferences in treatment of patients with asthma, COPD or allergic rhinitis and concomitant diseases. AIM The assessment of doctors' preferences in phar...

The authors examined 179 veterans with chronic obstructive pulmonary disease (COPD) to determine the relative contribution of clinical depression and/or anxiety (Beck Depression and Beck Anxiety Inventories) to their quality of life (Chronic Respiratory Questionnaire and Medical Outcomes Survey Short Form). Multiple-regression procedures found that both depression and anxiety were significantly...

BACKGROUND Our objective was to develop a tool to identify patients with COPD for proactive palliative care. Since palliative care needs increase during the disease course of COPD, the prediction of mortality within 1 year, measured during hospitalizations for acute exacerbation COPD (AECOPD), was used as a proxy for the need of proactive palliative care. PATIENTS AND METHODS Patients were re...

BACKGROUND Poor sleep quality is often reported among patients with COPD. Pulmonary rehabilitation (PR) is beneficial in improving exercise capacity and health-related quality of life (HRQOL). However, its benefit in terms of sleep quality in patients with COPD remains unclear. This study aimed to investigate the effects of PR on sleep quality of patients with COPD. METHODS Thirty-four subjec...
