    Abstract:
    World COPD day is an annual event intended to increase awareness of chronic obstructive pulmonary disease. During this day, in November 2006, free spirometry testing was offered to the public in approximately 100 places including hospitals, pharmacies, offices of GPs and tents on main squares throughout the Netherlands. The objective of this action is laudable. However, screening for COPD is generally considered ineffective. Furthermore, the application of a fixed ratio of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) (FEV1/FVC < 0.70) as recommended by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) to detect airflow limitation, required for a diagnosis of COPD, may lead to underdiagnosis of COPD in the young and to overdiagnosis in the elderly. In addition, spirometry was generally performed without bronchodilation, thus further increasing the likelihood of a false-positive diagnosis ofCOPD. Smoking cessation is important in halting the progression of COPD. Therefore, identifying smokers at risk for developing COPD seems a logical reason for screening or case finding for COPD. However, it has not been clearly demonstrated that early detection of COPD may contribute to improved smoking cessation rates. Also, smokers with normal spirometry may be led to believe that smoking has no adverse effects on their health. Therefore, a different strategy should be adopted to increase awareness of COPD on the next World COPD day.
