Itch and pruritus is graded on visual analogue scale (VAS) measuring 6.6 cm in length and scored from 0 to 10.
points for itch =
= (score along itch scale) * 1.5
total score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 40 + 72 + 15 = 127
• The higher the score, the more severe the disease.
In addition, the patient gave a global score for disease severity similar to the itch and pruritus VAS.
