The SCORAD Index (SCORing Atopic Dermatitis) is a scoring index for measuring the severity of atopic dermatitis. It is intended to standardize the assessment of atopic dermatitis and to help in the interpretation of therapeutic studies. It was designed to be easy to use in the outpatient setting.
The SCORAD Index is based on 3 subscores:
(1) A (extent score based on body surface area)
(2) B (intensity score based on 6 clinical findings in atopic dermatitis)
(3) C (subjective symptoms)
A = extent score =
= SUM (body surface area involved, using rule of 9)

where:
• The intensity is based on the average intensity in a representative area.
• Dryness is evaluated in uninvolved areas.
C = subjective symptoms of pruritis and sleep loss =
= (score for pruritis from 0 to 10) + (score for sleep loss from 0 to 10)
where:
• Pruritis and sleep loss are graded on a visual analog scale ranging from 0 (none) to 10 (extreme)
• The severity is based on the average extent for the last 3 days or nights.
SCORAD index =
= (A / 5) + (7 * B / 2) + C
