Multicenter StudyBarriers to adherence to chronic obstructive pulmonary disease guidelines by primary care physicians.
Even with the dissemination of several clinical guidelines, chronic obstructive pulmonary disease (COPD) remains underdiagnosed and mismanaged by many primary care physicians (PCPs). The objective of this study was to elucidate barriers to consistent implementation of COPD guidelines. ⋯ Adherence to guideline recommendations of spirometry use was predicted by agreement with the recommendations, self-efficacy, perceived outcome expectancy if recommendations were adhered to, and resource availability. Adherence to recommendations of LABD use was predicted by agreement with guideline recommendations and self-efficacy. Increasing guideline familiarity alone may have limited patient outcomes, as other barriers, such as low confidence and outcome expectancy, are more likely to impact guideline adherence.

Excessive visceral fat accumulation in advanced chronic obstructive pulmonary disease.
Previous studies have suggested links between chronic obstructive pulmonary disease (COPD), cardiovascular disease, and abdominal obesity. Although abdominal visceral fat is thought to be associated with cardiovascular risk factors, the degree of visceral fat accumulation in patients with COPD has not been directly studied. The aim of this study was to investigate the abdominal visceral fat accumulation and the association between visceral fat and the severity and changes in emphysema in COPD patients. ⋯ COPD patients have excessive visceral fat, which is retained in patients with more advanced stages of COPD or severe emphysema despite the absence of obesity.

Comparative StudyCost trends among commercially insured and Medicare Advantage-insured patients with chronic obstructive pulmonary disease: 2006 through 2009.
Few estimates of health care costs related to chronic obstructive pulmonary disease (COPD) are available regarding commercially insured patients in the United States. The aims of this retrospective observational analysis of administrative data were to describe and compare health care resource use and costs related to COPD in the United States for patients with commercial insurance or Medicare Advantage with Part D benefits, and to assess cost trends over time. ⋯ COPD imposed a substantial economic burden on patients and the health care system, with costs increasing significantly in both the Medicare and commercial populations.

Determinants of polypharmacy and compliance with GOLD guidelines in patients with chronic obstructive pulmonary disease.
Polypharmacy of respiratory medications is commonly observed in patients with chronic obstructive pulmonary disease (COPD). The aims of this study were to investigate determinants of polypharmacy and to study the consistency of actual respiratory drug use with current Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines in pulmonary rehabilitation candidates with COPD. ⋯ Polypharmacy of respiratory medications is common in COPD patients with persistent symptoms. In addition to severity of disease, health status is an independent predictor of polypharmacy. Actual drug use in COPD patients referred for pulmonary rehabilitation is partially inconsistent with current GOLD guidelines.

Disability related to COPD tool (DIRECT): towards an assessment of COPD-related disability in routine practice.
Chronic Obstructive Pulmonary Disease (COPD) is a worldwide public health concern. It is also a major source of disability that is often overlooked, depriving patients of effective treatments. This study describes the development and validation of a questionnaire specifically assessing COPD-related disability. ⋯ DIRECT is a promising tool that could help enhance the management of COPD patients by integrating an evaluation of the COPD-related disability into daily practice.
