Objective:
To evaluate the effectiveness of a screening programme for COPD in primary care.
Material/Methods:
Subjects aged 65 years or older registered with a general practitioner in Copenhagen were asked to complete a questionnaire on smoking status and symptoms of COPD. If they were smokers or former smokers or if morning cough with sputum and/or dyspnoea was present, subjects were defined as "at risk of COPD" and were invited to undergo spirometric examination.
Results:
Of the 7103 subjects who met the study criteria, 81.2% responded to the questionnaire. Of these, 58.5% were at risk of COPD. Of those at risk, 40% underwent a spirometric examination. COPD was classified as mild in 252 (42.3%), moderate in 258 (43.3%) and severe-very severe in 86 subjects (14.4%). The participation rate was significantly higher among subjects invited for spirometry at a healthcare centre compared to general practice.
Conclusions:
Our findings suggest that a questionnaire can be used as a screening tool to identify subjects at risk of COPD. Furthermore, the study shows that more than half the subjects aged 65 years and above were at risk of COPD and required clinical assessment. Willingness to undergo spirometric examination depends on the location of the screening.
