French Validation of the CAPTURE Case Finding Tool for Obstructive Respiratory Disease

French Validation of the CAPTURE Case Finding Tool for Obstructive Respiratory Disease

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.

A large number of healthcare professional across the country will screen participants.

Participants willing to participate 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.

At the end of each center's participation, a questionnaire will be sent to all healthcare professionals working on the study, to assess the ease of use of spirometry and the CAPTURE tool and its possible implementation in clinical practice.
