Example
- MDHAQ function sum
- 18
- Pain VAS
- 4
- Patient-global VAS
- 5
Result: RAPID3 15/30 — high severity.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Categories
- Near-remission ≤ 3, low 3.1–6, moderate 6.1–12, high > 12.
What you enter
- MDHAQ function sum (0–30)
- Pain VAS (0–10)
- Patient-global VAS (0–10)
How this is calculated
- Formula
- Function (10-item MDHAQ 0–30 ÷3) + pain VAS + global VAS, each 0–10, summed to 0–30.
