📊 EASI Eczema Area Severity Index Calculator Simulator

Scoring Body Region Area Involvement

Placeholder sentence introducing regional area scoring.

• 4: Regions scored (head, arms, trunk, legs)
• 0–6: Area score range (per region scale)
• 6: BSA bands (0,<10,<30,<50,<70,<90,90-100)
• 1.0: Region weights sum (0.1+0.2+0.3+0.4)

Area score banding

Placeholder short paragraph about converting percent affected into a 0-6 band score.

Grading Erythema and Edema/Papulation

Placeholder sentence introducing inflammatory sign grading.

• 0–3: Sign scale (none to severe)
• 2: Signs this stage (erythema, edema/papulation)
• 4: Total signs (per EASI region)
• Visual: Assessment mode (clinician exam)

Inflammatory sign grading

Placeholder short paragraph on grading redness and swelling severity.

Grading Excoriation Severity

Placeholder sentence introducing excoriation grading.

• 0–3: Sign scale (none to severe)
• Scratch damage: Marker (visible skin breaks)
• Yes: Region-specific (scored independently)
• Itch proxy: Clinical relevance (pruritus severity)

Excoriation assessment

Placeholder short paragraph on scoring scratch-related skin damage.

Grading Lichenification Severity

Placeholder sentence introducing lichenification grading.

• 0–3: Sign scale (none to severe)
• Skin thickening: Marker (chronic rubbing sign)
• High: Chronicity (reflects long-standing disease)
• Yes: Region-specific (scored independently)

Lichenification assessment

Placeholder short paragraph on scoring skin thickening severity.

Calculating the Weighted EASI Total

Placeholder sentence introducing the final weighted score.

• 0–72: Score range (full EASI scale)
• 3: Formula parts (signs, area, region weight)
• 6: Severity bands (clear to very severe)
• 4: Regions combined (weighted sum)

Final weighted computation

Placeholder short paragraph on combining sign and area scores into EASI.

Placeholder: EASI = sum of (signs x area score x region weight) across four regions.
