The Eczema Area and Severity Index (EASI) stratifies severity of eczema.

What is an EASI score? An EASI score is a tool used to measure the extent (area) and severity of atopic eczema (Eczema Area and Severity Index). It takes a few minutes and experience to calculate it accurately.

The Eczema Area and Severity Index (EASI) was developed in 1998 and later validated to meet the demands of investigators in need of a standardized evaluation tool for severity of atopic dermatitis (AD) signs in clinical studies. 1,2 It was designed by modifying the Psoriasis Area and Severity Index scoring system, an assessment developed for ...

EASI demonstrated adequate psychometric properties, including validity, responsiveness, internal consistency, and intraobserver and interobserver reliability.4 Because of the performance of the scale and endorsement by the HOME group, the EASI has be-come the most widely utilized signs/severity scale in AD trials.5

The EASI is a static score, meaning that it is done independently at each time point to reflect current severity. You should grade the EASI per visit regardless of the previous status.

To assess the extent and severity of atopic dermatitis (AD) or eczema at 4 body sites (Head/neck, Trunk, Upper extremities and Lower extremities) and measure 4 clinical signs, Erythema, Inuration/Papulation, Excoriation and Lichenification, in a simple, effective, comprehensive, consistent, and flexible way for a range of patients.

The Eczema Area and Severity Index (EASI) is a validated tool for the measurement of severity of atopic dermatitis. It ranges from 0 (no disease) to 72 (maximal disease). [1] [2] The EASI was developed in 1998 by modifying the Psoriasis Area and Severity Index (PASI), a widely accepted scoring system for psoriasis. [3]

The EASI evaluation involves assessing 4 body regions—head, trunk, and upper and lower extremities—across 2 domains of disease activity, percent of body surface affected, and the intensity of lesional skin into one composite score.

An EASI score is a tool used to measure the extent (area) and severity of atopic eczema (Eczema Area and Severity Index). It takes a few minutes and experience to calculate it accurately. Then it’s easy! EASI score does not include a grade for dryness or scaling. Include only inflamed areas.
