This research aims to evaluate the effectiveness of a 2-stage screening program for early COPD detection.
Subjects aged 65+ with GP registration in eastern Copenhagen participated.
Participants completed a questionnaire addressing smoking status and COPD symptoms.
Spirometry was offered to smokers, former smokers, or those presenting specific symptoms.
Out of 7103 subjects, 5767 (81.2%) returned the questionnaire, 58.5% were at risk of COPD.
Participation rates were 35% in practices not performing spirometry and 60% at local health centres.
Spirometry results indicated that 44% of those tested were diagnosed with COPD, with varying severity classifications.

Lyngsø et al. (2011) studied this question.
