    Abstract:
    OBJECTIVES: To determine adherence of emergency department (ED) management of acute exacerbation of chronic obstructive pulmonary disease (COPD) to current treatment guidelines. DESIGN: A prospective cohort study, as part of the Multicenter Airway Research Collaboration. SETTING: The study was performed at 29 EDs in 15 U.S. states and three Canadian provinces. PARTICIPANTS: ED patients, aged 55 and older, who presented with COPD exacerbation and underwent a structured interview in the ED and another by telephone 2 weeks later. MEASUREMENTS: Adherence of ED management of COPD exacerbation to that recommended in current treatment guidelines. RESULTS: The cohort consisted of 397 subjects, of whom 224 (56%) reported only COPD and 173 (44%) reported asthma and COPD. The average age was 70. Most (80%) patients had used rescue medications in the 6 hours before seeking emergency care. Only 31% were evaluated using spirometry and 48% using arterial blood gas measurement. ED treatment included inhaled short-acting beta-agonists for 91% of patients, inhaled anticholinergics for 77%, methylxanthines for 0.3%, systemic corticosteroids for 62%, and antibiotics for 28%. More than half the patients required hospitalization. At 2-week follow-up, 43% of patients reported a relapse event or ongoing exacerbation. Overall, adherence to national and international guidelines was low. CONCLUSION: Important differences exist between guideline recommendations and actual ED management of COPD exacerbations in older adults. Outcomes after ED treatment are poor and may be related to these shortcomings in quality of care. Better adherence to guideline recommendations when caring for elderly patients with COPD exacerbations may lead to improved clinical outcomes and better resource usage.
