What is a PASI?
• Psoriasis
• Area
• Severity
• Index
• Objectively quantifies severity of psoriatic lesions and measures body surface area affected by psoriasis

Why PASI?
• Required to qualify for drug reimbursement scheme
• Required to demonstrate response and qualify for continued drug reimbursement
