The '''SCORAD''' ("SCORing Atopic Dermatitis") index is a clinical tool for assessing the extent of the disease, disease intensity, and subjective symptoms of [[atopic dermatitis]].<ref>{{Cite journal |last1=Angelova-Fischer |first1=I. |last2=Bauer |first2=A. |last3=Hipler |first3=U.

== Calculation ==
To calculate the SCORAD index, the extent of disease is determined using the [[Wallace rule of nines|rule of nines]] to estimate percentage of the affected body surface area. The maximum value for the extent of the disease is 100%.
Disease intensity is then calculated based on six characteristics: [[erythema]], [[edema]], oozing/crusts, excoriations, [[lichenification]], and dryness. Each characteristic is given a score between 0 and 3, where 0 is absent and 3 is severe. The scores for each characteristic are added together for a total intensity score of up to 18.
Subjective symptoms including sleep loss and [[pruritus]] are measured using a 10&nbsp;cm [[visual analogue scale]] with a total maximum score of 20.
The SCORAD index is then calculated with the following formula:
:<math>\text{Extent}/5 + 7\times \text{Intensity}/2 + \text{Subjective Symptoms}</math>
