Extent (A) — Mapping Affected Body Surface Area
Placeholder: extent uses a rule-of-nines body map scored zero to one hundred.
- 0–100: Score range (percent body surface)
- Rule of nines: Method (placeholder text)
- A/5: Weight in formula (placeholder text)
- Clinician: Assessor (placeholder text)
How extent is measured
Placeholder: clinician estimates percent skin surface affected by eczema.
Intensity (B) — Six Clinical Signs Scored
Placeholder: six signs each scored zero to three for a max of eighteen.
- 6: Signs scored (placeholder text)
- 0–3: Each sign range (placeholder text)
- 18: Max total B (placeholder text)
- 7B/2: Weight in formula (placeholder text)
The six signs
Placeholder: erythema, edema, oozing, excoriation, lichenification, dryness.
Subjective (C) — Itch and Sleep Loss
Placeholder: patient rates itch and sleep loss on ten-point scales.
- 0–10: Itch scale (placeholder text)
- 0–10: Sleep loss scale (placeholder text)
- 20: Max total C (placeholder text)
- Patient: Reporter (placeholder text)
Why subjective symptoms matter
Placeholder: captures quality-of-life burden objective signs miss.
Combining A, B, and C into One Score
Placeholder: SCORAD = A/5 + 7B/2 + C weights each component.
- A/5+7B/2+C: Formula (placeholder text)
- 83: Objective max (placeholder text)
- 20: Subjective max (placeholder text)
- 103: Total max (placeholder text)
Why these weights
Placeholder: weighting reflects each component's clinical importance.
Total SCORAD — Classifying Disease Severity
Placeholder: total score sorts patients into mild, moderate, severe bands.
- <25: Mild (placeholder text)
- 25–50: Moderate (placeholder text)
- >50: Severe (placeholder text)
- 103: Max possible (placeholder text)
Using the score clinically
Placeholder: guides treatment intensity and tracks response over time.
Placeholder: SCORAD is widely used in eczema trials and clinics.
