Brief summary
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.
Detailed description
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.

|---|---|---|
| Sensitivity, specificity and area under the ROC curve of the CAPTURE tool | Baseline | Sensitivity, specificity and area under the ROC curve of the CAPTURE tool; i.e. its ability to identify undiagnosed patients with an obstructive ventilatory disorder assessed with a portable spirometry. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of patients who have taken steps to enter a healthcare pathway 6 months after the referral to a doctor | 6 months after | Number of patients screened by the CAPTURE tool who have taken steps to enter a healthcare pathway 6 months after the referral to a doctor, i.e. the impact of the screening process at 6 months on patient diagnosis, management and follow-up. |
| Primary care investigators' opinion of the CAPTURE tool used in this study | Baseline to 2 years | Responses on a Likert scale from all investigators to a questionnaire on the easiness of use of spirometry and CAPTURE tool and its implementation in clinical practice once each center's inclusions had been completed. |
