Quantification of the Extent and the Severity of Atopic Dermatitis: The ADASI Score

To the Editor.— The assessment of the area and of the severity of atopic dermatitis is of considerable importance.¹Unfortunately, the current scoring systems are rather complicated.¹,²Thus, we propose a simple scoring system based on color coding of diseased areas according to their severity on body schemes. The extent of the colored areas is evaluated by point counting. We use the following color coding: green, discret erythema with or without some scaling, no infiltration; blue, erythema with some infiltration, more or less scaling; and red, marked erythema with infiltration, with or without scaling; or lichenification with or without excoriation, with or without superinfection. The area fractions of the colored parts on the schemes (height about 18 cm) are determined by point counting with a grid of parallel lines 2-cm apart (Figure). The number of points on the area to be determined, divided by the total number of
