SCORing Atopic Dermatitis - Comprehensive severity assessment tool
SCORAD Assessment
AExtent of Lesions (% body surface area affected)
Estimate the percentage of each body area affected by eczematous lesions using the rule of nines.
Total Extent: 0.0% of body surface area
BIntensity of Clinical Features
Rate each clinical feature from 0 (absent) to 3 (severe) in the most affected areas.
Total Intensity Score: 0/18 points
CSubjective Symptoms
Rate symptoms over the past 3 days/nights using a Visual Analogue Scale (0-10).
Total Subjective Score: 0/20 points
SCORAD Formula
SCORAD = A/5 + 7B/2 + C
A: Extent (0-100%)
B: Intensity (0-18 points)
C: Subjective symptoms (0-20 points)
Severity Scale
Understanding SCORAD
What is SCORAD?
SCORAD (SCORing Atopic Dermatitis) is a standardized clinical assessment tool used to evaluate the severity of atopic dermatitis (eczema). It combines objective clinical signs with subjective patient symptoms to provide a comprehensive severity score ranging from 0 to 103.
Clinical Applications
- •Monitoring treatment response and disease progression
- •Clinical research and drug development studies
- •Standardizing severity assessment between clinicians
- •Guiding treatment intensity decisions
SCORAD Components
A - Extent (0-100%)
Body surface area affected, calculated using the rule of nines with appropriate weighting for different body regions.
B - Intensity (0-18)
Six clinical features: erythema, edema, excoriation, lichenification, oozing/crusting, and dryness, each scored 0-3.
C - Subjective (0-20)
Patient-reported symptoms: itching and sleep loss, each rated 0-10 using visual analogue scales.
Assessment Guidelines
Extent Assessment
- • Use rule of nines for body regions
- • Assess only eczematous lesions
- • Include both active and healing lesions
- • Maximum total extent is 100%
Intensity Scoring
- • Assess most severely affected areas
- • 0 = Absent, 1 = Mild, 2 = Moderate, 3 = Severe
- • Dryness assessed in unaffected areas
- • Representative lesions only
Subjective Symptoms
- • Based on past 3 days/nights
- • Use visual analogue scale 0-10
- • Patient or parent assessment
- • Consider average over time period
Important: SCORAD assessment requires clinical expertise and should be performed by trained healthcare professionals. The tool is most useful for monitoring changes over time rather than making absolute severity judgments.
