Evaluation of Plaque Psoriasis Severity
In clinical practice, the physician generally makes a subjective, qualitative assessment of the severity of a patient's plaque psoriasis by combining the following observations/assessments10:
- Body surface area (BSA) involvement
- Symptoms
- Location of psoriasis
- Thickness of plaques
- Presence or absence of psoriatic arthritis
- Subjective assessment of the impact of the disease on the patient's life
Involvement of plaque psoriasis on the hands, feet, face, and genitals should be considered in evaluating the severity of disease.10
