Identification Of Occupational Exposures In Patients With ILD

Hospices Civils de Lyon150 enrolled

Overview

Diffuse interstitial lung disease brings together a heterogeneous group of pulmonary pathologies, characterized by infiltrating and diffuse lesions of the pulmonary interstitium. The evolving risk of these ILD is pulmonary fibrosis, with the development of chronic respiratory failure. The process of the etiological diagnosis of ILD results from a multidisciplinary approach (pulmonologists, radiologists, occupational health specialists, anatomo-pathologists, etc…). Indeed, the multitude of possible causes of these diseases makes the etiological diagnosis difficult. Professional aetiologies are also frequently mentioned : pneumoconiosis, hypersensitivity pneumonitis, as a differential diagnosis. It therefore appears essential to deepen the professional aspect during the diagnostic process for ILD. Since May 2020, a professional interview has been systematically offered by the Occupational Pathology Consultation Center of the Hospital Center Lyon Sud, to patients followed by the team of Professor Vincent COTTIN, whose file was discussed in a multidisciplinary meeting. The data collected to constitute a database are the following variables: age, sex, diploma, professional course coded in CITP (International Standard Classification of Professions) and NAF (French Nomenclature of Activities), occupational exposures, smoking, risk factors non-professionals, clinical elements of ILD and elements relating to an occupational disease certificate. This database is anonymized.

Interventions

The data collected are the following variables: age, sex, diploma, professional course coded in CITP (International Standard Classification of Professions) and NAF (French Nomenclature of Activities), occupational exposures, smoking, risk factors non-professionals, clinical elements of ILD and elements relating to an occupational disease certificate. This database is anonymized. The precise diagnosis of ILD is retained during the multidisiciplinary meeting. Occupational exposures are assessed in specialized consultation : * a first professional interview phase: The professional history is traced, listing the training courses followed and the trades carried out. The questioning is precise and focuses on the different tasks performed, and the products used. * a second step, where a questionnaire is completed by the doctor: A list of specific substances is offered to the patient, who responds whether or not he thinks he has been exposed to them in his professional past.

Outcomes

Primary Outcomes

Study the distribution of occupational exposures according to the types of ILD. The precise diagnosis is retained during the multidisiciplinary meeting.

Precise diagnosis of ILD : type of PID diagnosed

Time frame: The precise diagnosis of ILD is retained immediately after the multidisiciplinary meeting.

Occupational exposures are assessed in specialized consultation by the occupational physician.

Occupational exposures

Time frame: Occupational exposures are assessed immediately after the occupational consultation.
