Abstract
Q Does an early COPD diagnosis improve long-term outcomes? Evidence-based answer: It depends. A diagnosis of chronic obstructive pulmonary disease (COPD) made using screening spirometry in patients without symptoms does not change the course of the disease or alter smoking rates (strength of recommendation [SOR]: A, preponderance of evidence from multiple randomized controlled trials [RCTs]). However, once a patient develops symptoms of lung disease, a delayed diagnosis is associated with poorer outcomes (SOR: B, cohort studies). Active case finding (including the use of spirometry) is recommended for patients with risk factors for COPD who present with consistent symptoms (SOR: C, expert opinion).
