VasculitisDamage index

VDI

Vasculitis Damage Index. 64 items in 11 systems, each scored present (1) or absent (0). It records cumulative damage, not current activity. Total 0 to 64.

For clinicians only. This tool is for healthcare professionals and clinical education only. It does not diagnose, replace clinical judgement, or replace specialist assessment. Any decisions about a patient must be based on full clinical assessment, investigations where appropriate, and current clinical guidelines.

How to score

Record damage that has developed or worsened since the onset of vasculitis and has been present for at least 3 months.
The VDI is cumulative: include qualifying damage even if it has since resolved, and carry forward items recorded at previous assessments.
Exclude comorbidity that existed before onset and has not changed. Damage need not be attributed to vasculitis; it may be due to treatment or another cause after onset.
For discrete events (for example myocardial infarction, stroke or surgery), wait until at least 3 months after the event. Repeat episodes must be at least 3 months apart.
Do not count the same pathological lesion twice. Current disease activity is assessed separately with BVAS.
This is a single anonymous assessment. Nothing is saved. Please do not enter patient names or identifiers.

I have reviewed all sections using the VDI scoring instructions

Interpretation

The total is the number of items present (0 to 64). The VDI has no validated severity bands, and this tool does not offer a diagnosis, prognosis or treatment recommendation.

This implementation follows the published form and scoring instructions; it has not been independently clinically validated or endorsed by the instrument's authors.
