    When to Use
    Pearls/Pitfalls
    Why Use

    Patients >8 years old with atopic dermatitis, to assess severity and extent.

    • EASI is one of the most widely used instruments in assessing atopic dermatitis in both clinical and trial settings. 

    • EASI is less reliable when assessing patients with darker skin.

    • Easily understood and simple system used to track disease progression. 

    • May be used in pediatric patients.

    • Used in clinical trials of therapies for atopic dermatitis.

    • In Australia, EASI is used to determine eligibility for government subsidized prescription drugs.
