Background:
Psoriatic disease (PsD) is a chronic, multisystem, inflammatory disorder encompassing psoriasis, psoriatic arthritis (PsA), and their associated comorbidities.
Objective:
The aim of this subanalysis of the global "Psoriasis and Beyond" study was to evaluate patients' experiences of living with PsD in the USA.
Methods:
The study included a cross-sectional, quantitative, 25-min online survey of adults with self-reported, healthcare professional-diagnosed, moderate-to-severe psoriasis, with or without PsA. USA-based patients were recruited through online panels by the Institut de Publique Sondage D'Opinion Secteur and The National Psoriasis Foundation.
Results:
This analysis included 793 US patients with psoriasis; 43% also had PsA. Overall, 75% of patients knew that their disease was systemic, and 65% had heard the term "psoriatic disease." Of patients without diagnosed PsA, 50% screened positive for PsA using the Psoriasis Epidemiology Screening Tool. Psoriasis negatively affected emotional well-being and quality of life (QoL) in the majority of patients (87% and 91%, respectively). Overall, 29% of patients reported that they could not work or study in the week prior to the survey; of these, 98% responded that psoriasis had a very or extremely large impact on their QoL. Mean diagnostic delays of 3.7 and 3.3 years for psoriasis and PsA, respectively, were reported.
Conclusions:
This analysis of USA-based patients with PsD highlights the profound impact of PsD on emotional well-being and QoL and suggests potential underdiagnosis of PsA. There is a need to ensure early PsD diagnosis and to provide holistic treatment, including mental health support.
