Study of the Use of Non-invasive Ventilation in Bronchial Dilatation Disease

Non-invasive ventilation is a treatment sometimes used for severe severe bronchial dilatation, but to date there are no studies its efficacy.

The expected results in this context are :

• a description of the characteristics of patients with severe bronchial on non-invasive ventilation (NIV)
• a better understanding, during NIV management, of the settings used, the tolerance and effectiveness of NIV in reducing exacerbations, hospital admissions and patient mortality.
• move towards better patient management

Data will be extracted from patient medical records and the PMSI.

Inclusion criteria

• Patients over 18 years
• Predominant diagnosis of bronchiectatic disease, excluding cystic fibrosis, confirmed by computed tomography
• Introduction of long-term NIV at a given point in the patient's care

Exclusion criteria

• Patient's opposition to participating in this study
• Cystic fibrosis
• Predominant diagnosis of COPD or asthma, traction bronchiectasis, bronchiectasis resulting from focal endobronchial lesion, sarcoidosis or active allergic bronchopulmonary aspergillosis.
