COPD

Chronic obstructive pulmonary disease (COPD) is the third-leading cause of death in the United States. Despite clinical practice guidelines endorsed by national organizations, the management of COPD deviates from guideline recommendations. Patients with COPD are frequently underdiagnosed and misdiagnosed, due in large part to the lack of spirometry testing. ⋯ System factors such as insurance coverage may limit aspects of COPD care. To overcome clinical inertia, a multifaceted approach is required. Provider and patient education, the use of health informatics, changes in provider work-flow and the recent development of performance measures, such as the use of spirometry in patients with COPD, can improve the delivery of recommended care for COPD patients.

Triple therapy for COPD consists of a long-acting anti-cholinergic bronchodilator, a long-acting beta-agonist bronchodilator, and an inhaled corticosteroid. Guidelines from the Canadian Thoracic Society advocate triple therapy for some patients with moderate-to-severe COPD. The objective of this review was to evaluate the evidence based clinical efficacy of triple therapy compared to dual bronchodilator therapy (long-acting anti-cholinergic bronchodilator + beta-agonist bronchodilator) or long-acting anti-cholinergic bronchodilator monotherapy for managing COPD. ⋯ Lung function, dyspnea and quality of life data show statistical significant changes with triple therapy compared to long-acting anti-cholinergic bronchodilator monotherapy but the changes do not reach clinical importance. Triple therapy does decrease the number of hospitalizations for severe/acute COPD exacerbations compared with long-acting anti-cholinergic bronchodilator monotherapy. There is insufficient evidence to determine if triple therapy is superior to dual bronchodilator therapy.

Airway clearance is a key component of respiratory physiotherapy management for patients with excess secretions, including patients with chronic obstructive pulmonary disease (COPD). The aim of this review is to give an overview of the available evidence for the use of different airway clearance techniques (ACT) and their effects in patients with COPD. ⋯ Studies that provide solid evidence of the effectiveness of different airway clearance techniques in patients with COPD are rather scarce. The available evidence indicates that active breathing techniques, such as active cycle of breathing techniques, autogenic drainage and forced expiration, can be effective in the treatment of COPD. The evidence for passive techniques such as postural drainage and percussion is low. Supporting techniques such as intrapulmonary percussive ventilation, positive expiratory pressure and non-invasive ventilation have little evidence because of the small number of studies. Little evidence is found for the combined use of active techniques and supporting techniques such as (oscillating) positive expiratory pressure, postural drainage and vibration in COPD patients. There is clearly a need for well-powered controlled clinical trials on the long-term effects of (combined) airway clearance techniques in COPD.

Chronic obstructive pulmonary disease (COPD) poses a significant economic burden on society, and a substantial portion is related to exacerbations of COPD. A literature review of the direct and indirect costs of COPD exacerbations was performed. A systematic search of the MEDLINE database from 1998-2008 was conducted and supplemented with searches of conference abstracts and article bibliographies. ⋯ Unreported exacerbations are common and may influence the long-term costs of exacerbations. Measurement of indirect costs will provide a more comprehensive picture of the burden of exacerbations. Evaluation of pharmacoeconomic analyses would be aided by the use of more consistent and comprehensive approaches to defining and measuring COPD exacerbations.

Recent advances in chronic obstructive pulmonary disease (COPD) treatment offer symptom relief, but disease modification remains an unmet goal of pharmacotherapy. Reducing the frequency and severity of COPD exacerbations may help slow disease progression and reduce the morbidity, mortality, and costs associated with these major events. Other desirable characteristics for a COPD treatment include a once-daily dosing schedule, an oral formulation, and a low frequency of systemic side effects. ⋯ Notably, this effect appeared to be greatest in the subgroup of patients with more severe disease and more severe exacerbations. The evaluation of roflumilast safety largely centers on gastrointestinal adverse events, with diarrhea, nausea, and weight loss occurring more frequently with the drug than placebo. If approved for general use, we expect roflumilast to find its role initially as a substitute for inhaled corticosteroids in the maintenance treatment of severe and very severe disease, particularly in patients who have frequent acute exacerbations, and perhaps as a supplementary drug when symptoms are not adequately controlled by current conventional COPD therapy.
