From the results of a pilot-study conducted in 13 community-pharmacies in Barcelona, in which the investigators showed the feasibility of spirometry in community-pharmacies for the early detection of COPD, the investigators have design a second phase to evaluate the effect of this strategy. 100 Barcelona's community-pharmacies during 6 months will select high risk customers and will conduct a spirometry in agreement with the design protocol. 3600 spirometries is the establish objective. Participants hospitals will train pharmacist in spirometry and also control spirometry quality daily by a telematic pathway. Spirometry results will be evaluate in terms of effect and costs. The investigators will also evaluate the impact of this program in the health system by numbers of subjects diagnosed and follow up in primary care.
