A large number of physiotherapist across the country will screen participants. Participants will have a short interview, and then will have to answer the 5-item CAPTURE questionnaire. They will be assisted to perform a peak expiratory flow measurement with a portable device. The comparison will be made between the CAPTURE decision and a portable spirometry assessing the presence or not of an obstructive disorder. Patient screened either by the tool or the spirometry will be addressed to a doctor. Follow-up at 6 months will be set up in order to assess the entry or not of those patients to an approved health care pathway.
The objective of this multicentre prospective study is to validate CAPTURE as a French case finding tool for undiagnosed patients suffering from obstructive pulmonary disease.
