EASI (Eczema Area and Severity Index)

EASI grades atopic dermatitis extent and severity across four body regions to quantify disease and track treatment response. Age affects region weighting: select the under-8 option for young children, since head/neck and lower-limb multipliers differ.

Age group (sets head/neck & lower-limb region weights)

Head/neck — Area involved

Head/neck — Lichenification

Upper limbs — Area involved

Upper limbs — Erythema (redness)

Upper limbs — Induration/papulation

Upper limbs — Excoriation (scratching)

Upper limbs — Lichenification

Trunk — Area involved

Trunk — Erythema (redness)

Trunk — Induration/papulation

Trunk — Excoriation (scratching)

Trunk — Lichenification

Lower limbs — Area involved

Lower limbs — Erythema (redness)

Lower limbs — Induration/papulation

Lower limbs — Excoriation (scratching)
