SCORing Atopic Dermatitis (SCORAD)

SCORAD is a clinical tool for assessing the severity (ie, extent, intensity) of atopic dermatitis, combining objective and subjective criteria.

Disease activity is assessed by grading:

• Six clinical signs (erythema, exudation, excoriation, dryness, cracking, and lichenification), each on a scale of 0 to 3
• Extent: Evaluates the area of skin affected by eczema, often using "rule of nine" to estimate the percentage of body surface area involved
• Subjective symptoms (itch and sleeplessness): using a visual analogue scale of 0 to 10

Area (A)

/

To determine extent, the sites affected by eczema are shaded on a drawing of a body. The rule of 9 is used to calculate the affected area (A) as a percentage of the whole body.
