Hospital Burden and Care Pathways of ANCA-Associated Vasculitis in Italy: A Focus on Clinical, Economic, and Geographic Dimensions

Background

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAVs) are rare autoimmune diseases characterized by heterogeneous clinical presentation and substantial morbidity. Evidence suggests high healthcare utilization and economic burden of ANCA-associated vasculitis (AAV), particularly owing to hospitalization as well as geographic variation in the organization of specialized care. However, national-level analyses examining outcomes, resource use, and geographic differences in care pathways remain limited.
