Recommendations

As issued by the authors

  1. Recognise alternative conditions mimicking psoriasis (PsO) (tinea, seborrheic dermatitis, eczema, pityriasis rubra pilaris, syphilis, cutaneous lymphoma) and consider referral to dermatology when skin disease is not responding to therapy

  2. Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) are gold standards in clinical trials but not practical in busy clinical practice; Physician global assessment (PGA), body surface area by handprint method and informal patient-reported outcomes can be useful to document disease burden

  3. A treat-to-target approach using a PGA of clear/almost clear is ideal
