Introduction to assessing the severity of eczema using EASI

4 body regions 2 1 : Head/Neck
2: Trunk
3: Upper extremities
4: Lower extremities

The EASI score Percentage of surface affected by eczema
for each body region Severity of 4 key signs for each body region
Erythema (redness)
Oedema / papulation
Excoriation (scratching)
Lichenification A B e.g. 50% of head and neck area is affected by eczema No requirement to add up the surface area of different body regions For each of the 4 body regions
1 : Head/Neck
2: Trunk
3: Upper extremities
4: Lower extremities

The EASI score B For each of the 4 body regions 1 : Head/Neck
2: Trunk
3: Upper extremities
4: Lower extremities Severity of 4 key signs for each body region
Erythema (redness)
Oedema / papulation
Excoriation (scratching)
Lichenification

Assess severity of 4 key signs in each body region

Erythema (redness)
Oedema / papulation (swelling and bumpiness)
Excoriation (scratch marks)
Lichenification (“leatheriness”)

Score the degree of severity of each sign for each body region separately

Scoring table - severity

Erythema (redness) assessed by visual examination

PO SCORAD training
www.opened-dermatology.com Erythema (redness)

2. Oedema/papulation assessments by palpation and visual examination

PO SCORAD training
www.opened-dermatology.com Oedema

Excoriation (scratching)

PO SCORAD training

4. Lichenification assessments by palpation and visual examination

Lichenification (“elephant skin”)

What if there are patches with different severity in the same body region? E.g. In upper extremities
One patch scores 2 for redness
Another patch scores 3 for redness

the average severity for redness in this body region will be 2.5

Eczema on dark skin

The EASI score A e.g. 50% of head and neck area is affected by eczema No requirement to add up the surface area of different body regions For each of the 4 body regions
1 : Head/Neck
2: Trunk
3: Upper extremities
4: Lower extremities Percentage of Surface affected by eczema
for each body region

4 body regions Tip - don’t get too hung up on accuracy – broad bands are used 2 1 : Head/Neck
2: Trunk
3: Upper extremities
4: Lower extremities

Head and Neck – start by using these percentages to guide you

Percentage of Surface affected by eczema
for each body region Assessed for each body region:
0 = None
1= <10%
2 = 10 to <30%
3 = 30 to <50%
4 = 50 to <70%
5 = 70 to <90%
6 = 90 to <100% Head/Neck : 27% = 2 Head/Neck 11% ie 1/3 of 33% 17%
ie all of back of neck which is 17%

Trunk

Percentage of Surface affected by eczema
for each body region Assessed for each body region:
0 = None
1= <10%
2 = 10 to <30%
3 = 30 to <50%
4 = 50 to <70%
5 = 70 to <90%
6 = 90 to <100% Trunk : 26 % = 2 Trunk 11% ie about 1/5 of 55% 15% ie about 1/3 of 45% Tip: you can “eyeball” whole area if you like, but tendency will be to overestimate

Upper extremities

Percentage of Surface affected by eczema
for each body region Assessed for each body region:
0 = None
1= <10%
2 = 10 to <30%
3 = 30 to <50%
4 = 50 to <70%
5 = 70 to <90%
6 = 90 to <100% Upper extremities : 24% = 2 Upper extremities 8+8 =16 4+4=8 Tip: If you really can’t work out rough % in your head, just imagine how many times the red area can be copied into the total area to fill it

Lower extremities

Percentage of Surface affected by eczema
for each body region Assessed for each body region:
0 = None
1= <10%
2 = 10 to <30%
3 = 30 to <50%
4 = 50 to <70%
5 = 70 to <90%
6 = 90 to <100% Lower extremities: 8% = 1 Lower extremities 4+4=8
