Abstract Background and Objective: The aim of this study was to develop and validate two
models to estimate the probabilities of frequent exacerbations (more than 1 per year) and …

Background COPD often coexists with chronic conditions that may influence disease
prognosis. We investigated associations between chronic (co) morbidities and …

Although exacerbation of chronic obstructive pulmonary disease (COPD) is important in

Information on exacerbations of chronic obstructive pulmonary disease (COPD) has mainly …

Background Exacerbations affect morbidity in chronic obstructive pulmonary disease
(COPD). We sought to evaluate the association between exacerbation frequency and …

There is little information available concerning the extent to which chronic obstructive
pulmonarv disease (COPD) patients are satisfactorily managed, especially, regards factors …

Purpose Acute COPD exacerbations account for much of the rising disability and costs
associated with COPD, but data on predictive risk factors are limited. The goal of the current …

Background Chronic obstructive lung disease (COPD) exacerbations are a significant cause
of morbidity and mortality. Data regarding factors which causes or prevents exacerbations is …

following an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) …

OBJECTIVE: Exacerbations of COPD requiring hospital admission have important clinical
and societal implications. We sought to investigate the incidence, recurrence, risk factors …
