Eczema Area and Severity Index (EASI)
For pediatric patients ≤7 years old
The Eczema Area and Severity Index (EASI) is a highly validated inventory with a long history. It is one of the most widely used instruments and is recommended as the core instrument in measuring signs in all atopic dermatitis (AD) clinical trials. It is easily understood and uses a simple system to track disease progression. The body is divided into 4 distinct regions. Four symptoms of AD as well as the area affected in each region are calculated and compiled to produce a score.
The EASI is suitable for all ages, but calculations may be adjusted based on the patient’s age.
Click here for patients aged ≥8 years old.
Each of the 4 regions is scored according to the area affected and the severity of symptoms.

Scoring Principle :

The area affected score is multiplied with the total intensity score for all symptoms in each region, then scaled by a multiplier unique to the body part as listed below:

  • Head and neck x 0.2
  • Trunk including genitals x 0.3
  • Upper limbs x 0.2
  • Lower limbs x 0.3

The score of EASL ranges from 0 to 72. A score of 0 indicates clear or no eczema, ≤1 indicates almost clear, 1.1-7 indicates mild disease, 7.1-21 indicates moderate disease, 21.1-50 indicates severe disease, and >50 indicates very severe disease.

If you are concerned that your eczema may not be well controlled, please seek medical advice. Bring your completed test results with you at your next scheduled consultation and speak to your doctor with the help of the test results to describe how your eczema is affecting you.
