To evaluate the prevalence of undiagnosed psoriatic arthritis in patients presenting with plaque psoriasis using the PASE (Psoriatic Arthritis Screening and Evaluation) questionnaire based on a score of ≥ 44 on the questionnaire
Time frame: 14 days
Evaluate the positive predictive value between PASE (Psoriatic Arthritis Screening and Evaluation) score ≥ 44 and rheumatologist-confirmed diagnosis of psoriatic arthritis in a population of tertiary Australian psoriasis patients
Time frame: 14 days
Evaluate the proportion of patients within the enrolled patient population with moderate-to-severe plaque psoriasis (PASI [Psoriasis Area and Severity Index] > 10)
Time frame: 1 day
Evaluate the proportion of patients in a tertiary population with moderate-to-severe psoriasis with respect to treatment history and current treatment
Time frame: 1 day
Describe quality of life (QoL) in a tertiary psoriasis patient population
Time frame: 1 day
Explore the relationship between disease severity and QoL (quality of life) and stratified by the presence or absence of psoriatic arthritis in a tertiary population
Time frame: 14 days
