EASI — Eczema Area and Severity Index

Validated severity score for atopic dermatitis (eczema) used to assess treatment response and biologic eligibility.

Age group (EASI weights differ for children under 8)*

Head/Neck: Area affected*

Head/Neck: Sum of severity (erythema + induration/papulation + excoriation + lichenification, each 0–3) [enter 0–12]*(points)

Trunk: Area affected*

Trunk: Sum of severity (0–12)*(points)

Upper Extremities: Area affected*

Upper Extremities: Sum of severity (0–12)*(points)

Lower Extremities: Area affected*

Lower Extremities: Sum of severity (0–12)*(points)

Score interpretation

Clear (EASI 0) 0

EASI 0: clear (Leshem 2015).

→ Maintenance emollients.

Almost clear (0.1–1.0) 0.01–1

EASI 0.1–1.0: almost clear.

→ Maintenance emollients; proactive topical treatment for known flare sites.

Mild eczema (1.1–7.0) 1.01–7

EASI 1.1–7.0: mild atopic dermatitis.

→ Regular emollients; topical corticosteroids or calcineurin inhibitors for active areas.

Moderate eczema (7.1–21.0) 7.01–21

EASI 7.1–21.0: moderate atopic dermatitis.

→ Escalate topical treatment; consider dermatology referral.

Severe eczema (21.1–50.0) 21.01–50

EASI 21.1–50.0: severe atopic dermatitis.

→ Dermatology referral; consider phototherapy or systemic treatment.

Very severe eczema (50.1–72.0) 50.01–72

EASI 50.1–72.0: very severe atopic dermatitis.

→ Urgent dermatology referral; consider phototherapy or systemic treatment.
