The diagnostic pathway and time to diagnosis in ANCA-associated vasculitis: a retrospective study at a tertiary rheumatology center

The diagnostic delay in AAV varies by disease subtype and clinical presentation. EGPA shows the numerically longest time to diagnosis, while renal involvement seems to facilitate earlier diagnosis. Enhanced awareness among non is essential to reduce diagnostic delay and prevent organ damage, although outcome measures were not assessed in our study. Key Points • Diagnostic delay in ANCA-associated vasculitis varies between disease subtypes, organ involvement, and consulted specialties. • EGPA shows the numerically longest diagnostic delay, whereas renal involvement seems to facilitate earlier diagnosis. • Earlier recognition of AAV across specialties may reduce diagnostic delay and prevent organ damage.
