| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Composite Index |
| Brief Description |
The CDA is a new tool to measure damage in AAV which is based on the Vasculitis Damage Index (VDI). It includes additional items of damage that were recorded in the Wegener’s Granulomatosis Etanercept Trial (WGET) but not captured by individual items on the VDI. |
| Number of Items | 26 |
| Range | 0-26 |
| Responses options/scale |
Yes Index |
| Developed for | Clinical practice, Research |
| PRACTICAL APPLICATION | |
| Method of administration | Physician |
| Recommendations to score | --- |
| Score Interpretation | A higher score indicates higher damage. |
| Cut-off points | --- |
| Cut-off points applied to | Not specified |
| Smallest detectable change if described | --- |
| Smallest detectable change applied to | Not specified |
| Completion time by the patient | - minutes |
| Scoring time by the assessor | 5-10 minutes |
| Training to score | Not necessary |
| Strengths | --- |
| Limitations | --- |

| Other Comments |
Feasiblity was good. 10/12 observers (83%) reported that the CDA was useful to record the natural history of vasculitis. All observers stated that the CDA covered the full spectrum of damage attributable to vasculitis. Five out of 12 observers (42%) found the CDA easy to complete. |
