What organ systems does VDI cover?

11 systems: musculoskeletal, cutaneous, ocular, ENT, pulmonary, cardiovascular, peripheral vascular, renal, nervous system, GI, and other (malignancy, infertility, avascular necrosis, diabetes). Items scored if present for ≥3 months.

What VDI score predicts mortality?

VDI ≥5 is associated with significantly increased mortality. Each additional VDI point increases mortality risk by 30%. Renal damage (CKD or ESRD) and pulmonary damage are major mortality contributors.

How does VDI differ from BVAS?

BVAS measures current disease activity (inflammation, potentially reversible). VDI measures cumulative irreversible damage from disease or treatment. Both are needed to fully characterize vasculitis outcomes.

Vasculitis Damage Index (VDI)

Calculate the Vasculitis Damage Index (VDI) for ANCA-associated and other systemic vasculitides. Measures cumulative irreversible damage across 11 organ systems independent of current disease activity.
