Patients with ANCA vasculitis seen in French occupational disease consultation centres.
Exclusion Criteria:
Number of diagnoses of ANCA vasculitis in the RNV3P
Number of diagnoses of ANCA vasculitis coded in the RNV3P or mentioned as the disease motivating the consultation in the summary by text mining search.
Time frame: 4 months
Imputability of the coded diagnoses of ANCA vasculitis.
Number of patients with ANCA vasculitis seen in consultation in occupational disease consultation centres for which a link between occupational and/or environmental exposure and the patient's ANCA vasculitis was retained.

Time frame: 4 months
Number of patients with ANCA vasculitis for whom other occupational and/or environmental exposure was identified.
Number of patients with ANCA vasculitis seen in consultation in occupational disease consultation centres for whom other occupational and/or environmental exposure was identified.
Time frame: 4 months
