Background And ObjectiveDetection of chronic obstructive pulmonary disease (COPD) is crucial in the management of COPD. The aim of this study was to establish the utility of a community-based lung cancer screening for detecting COPD.MethodsIn Japan, community-based lung cancer screening for residents who are 40 years or older using chest radiography is well established. A screening system in Chiba City, Japan, was used to detect COPD. The criteria to consider COPD at screening included age of 60 years or older, a smoking history and chronic respiratory symptoms. Participants fulfilling these criteria were referred for diagnostic evaluation consisting of pulmonary function testing (PFT) and chest computed tomography (CT).ResultsOf 89,100 Chiba City residents who underwent lung cancer screening, 72,653 residents were 60 years or older. Among them, 878 (1.0%) were identified with suspected COPD and referred for further evaluation. Of those identified, a total of 567 residents (64.6%, 567/878) underwent further evaluations, and 161 (28.4%) were reported to have COPD, with 38.5% of them requiring COPD treatment. To verify the diagnoses from the secondary evaluation centres, PFT and CT data were collected from 228 study participants, and 24.9% were diagnosed with COPD. CT findings classified according to the Goddard classification revealed that 20.1% of these participants had moderate to severe emphysema.ConclusionsCOPD screening added to a community-based lung cancer screening programme may be effective in the detection of patients with COPD.© 2013 The Authors.
