The National Psoriasis Foundation (NPF) developed a score for evaluating a patient with psoriasis. It can be used to evaluate the patient initially and to monitor the patient over time.
Parameters:
(1) assessment of induration in plaque A
(2) assessment of induration in plaque B
(3) body surface area (BSA) involved
(4) physician global assessment, static and defined (based on global assessment of erythema, induration and scaling averaged over all lesions)
(5) patient's global assessment
(6) patient's assessment of itch
